Product Detail

Product: SR3100 Schottky diode.
Rating: 3A, 100V.
Package: DO-201AD.
Use case: output rails.

Product Description

This SR3100 Schottky diode page is for low-loss output rails that need 3A current and 100V reverse-voltage class in a DO-201AD package. You can compare SR3100 by forward drop, reverse-voltage margin, hot leakage, surge rating, ripple current, body size and thermal behavior. It fits SMPS outputs, adapters, chargers and DC/DC boards where 40V Schottky parts may not leave enough spike margin. Lian Tuo helps you check the waveform before selecting samples. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Use More Voltage Headroom

An SR3100 Schottky diode is useful when a 40V Schottky is too close to the reverse-voltage spikes. The 100V class gives more headroom for SMPS outputs and adapter rails while keeping low forward drop benefits. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin.

Check Leakage At Heat

Higher-voltage Schottky parts still need leakage review at real temperature. An SR3100 Schottky diode should be checked in warm enclosures or standby paths so the extra voltage margin does not hide reverse-current problems. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Keep The 3A Package Honest

The DO-201AD body gives useful leaded assembly space, but it does not guarantee low temperature. SR3100 selection should include ripple current, copper area, airflow and lead mounting before your team approves it for production. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin.

Compare With 40V Parts

If the board originally used 1N5822 or SR240, moving to SR3100 can add voltage margin. The tradeoff may include forward drop and leakage changes. Lian Tuo can compare the options against your actual waveform. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Plan Current Upgrades

When SR3100 current margin is not enough, SR5100 may become the next comparison. Your replacement path should check package, current, voltage and heat together, so a stronger model does not create a mechanical or thermal surprise. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin.

Vertical Product Applications

SMPS Output Rails

Use an SR3100 Schottky diode in SMPS output rails when low forward drop is needed but 40V parts do not leave enough reverse margin. Review ringing, ripple current and package temperature before approval. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin.

Adapter Secondary Rectifiers

Adapter secondary rectifiers can use SR3100 when the output waveform needs 100V headroom. The selected diode should balance low VF, hot leakage and board heat inside the adapter housing. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin.

Charger Power Outputs

Charger power outputs may need SR3100 when current is around 3A and voltage spikes are higher than expected. You should verify thermal rise and reverse margin before moving to bulk purchasing. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Schottky Replacement Lists

Replacement lists often group SR240, 1N5822, SR3100 and SR5100 together. Lian Tuo can separate them by current, voltage and package so your substitute follows the board stress. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin.

FAQ

What is an SR3100 Schottky diode used for?

An SR3100 Schottky diode is used in 3A, 100V low-loss rectifier and blocking paths. It fits SMPS outputs, adapters, chargers and DC/DC boards that need more reverse-voltage margin than 40V Schottky parts. It also avoids treating every 3A Schottky as equal.

How is SR3100 different from 1N5822?

Both are commonly 3A DO-201AD Schottky directions, but SR3100 provides 100V reverse-voltage class while 1N5822 is a 40V direction. Voltage margin is the main difference. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Can SR3100 replace SR240?

Sometimes, if the larger current and package behavior fit the board. SR3100 adds 3A current and 100V margin, but forward drop, leakage and body size should be checked before replacing SR240. It also avoids treating every 3A Schottky as equal.

What data helps quote SR3100?

Send output voltage, current, package, old marking, quantity and application. For SMPS outputs, include ringing or peak reverse-voltage estimates so the 100V margin can be checked. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Why choose 100V Schottky instead of 40V?

Choose 100V when spikes, ringing or design tolerance make 40V too close to the limit. The extra voltage headroom can improve reliability, but leakage and forward drop should still be compared. It also avoids treating every 3A Schottky as equal.

When should I choose SR5100 instead?

Choose SR5100 when the board needs 5A current in a similar 100V Schottky direction. Current, surge, package heat and space should be reviewed before moving from SR3100 to SR5100. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.

Can Lian Tuo support SR3100 equivalents?

Yes. Lian Tuo can compare SR3100, 1N5822, SR240, SR5100 and SMD Schottky alternatives by current, voltage, package, leakage and application stress. It also avoids treating every 3A Schottky as equal. That keeps SR3100 tied to 100V waveform margin. It also avoids treating every 3A Schottky as equal.
