Product Detail

Product: TO-220 high voltage diode.
Packages: single, dual.
Focus: heat management.
Use case: power boards.

Product Description

This TO-220 high voltage diode page is for power boards that need a tab-mounted package with stronger heat handling than axial parts. You can compare MUR, FES, dual common-cathode and fast high-voltage TO-220 devices by reverse voltage, current, recovery behavior, pinout, tab connection, insulation pad needs and heat-sink contact. TO-220 packages are used in converters, chargers, inverters and industrial supplies where the diode must fit both the circuit and mechanical assembly. Lian Tuo helps you review pinout and thermal details before sampling. That keeps the tab-mounted choice tied to thermal reality.

Use The Tab Properly

A TO-220 high voltage diode gives the circuit a better heat path only when the tab is mounted correctly. Heat-sink contact, screw pressure, insulation pad and airflow all matter. Share the mounting method so the diode can be selected with real thermal behavior in mind. It also helps avoid a pinout problem after samples arrive.

Check Pinout Before Sampling

TO-220 diode packages can be single, dual common-cathode, dual common-anode or other configurations. A TO-220 high voltage diode replacement should match pinout and tab connection before voltage and current are approved. Wrong pinout can make a good diode unusable. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Match Recovery To Power Stage

MUR, FES and similar power families serve different switching and rectifier needs. A TO-220 high voltage diode should be reviewed by recovery speed, current waveform and heat generation. Power package size does not remove the need for waveform matching. It also helps avoid a pinout problem after samples arrive. That keeps the tab-mounted choice tied to thermal reality.

Plan Mechanical Clearance

Power boards have limits around height, screw access and insulation distance. Lian Tuo can compare TO-220 high voltage diode drawings, tab style and package options before samples so the part fits the heat sink and the circuit. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Vertical Product Applications

Power Supply Rectifiers

Use a TO-220 high voltage diode in power supply rectifier positions when current and heat exceed axial package comfort. The selected model should match pinout, recovery speed and heat-sink mounting. It also helps avoid a pinout problem after samples arrive. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Inverter Clamp Paths

Inverter clamp paths may need tab-mounted fast diodes that handle high-voltage spikes and switching stress. A TO-220 high voltage diode can fit when recovery, current and thermal contact are reviewed together. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Battery Charger Boards

Battery charger boards often need rectifier diodes that run warm for long periods. A TO-220 high voltage diode provides a heat-managed path when screw mounting and insulation requirements are planned early. It also helps avoid a pinout problem after samples arrive. That keeps the tab-mounted choice tied to thermal reality.

FAQ

How do I choose a TO-220 high voltage diode?

Start with voltage, current, recovery speed, pinout, tab connection, heat-sink condition and insulation needs. TO-220 selection is a thermal and mechanical decision as much as an electrical one. It also helps avoid a pinout problem after samples arrive. That keeps the tab-mounted choice tied to thermal reality.

What is a dual TO-220 diode?

It places two diode chips in one package, often common-cathode or common-anode. Pinout must be checked carefully because a dual part cannot replace every single diode layout. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Does the TO-220 tab need insulation?

It depends on the tab electrical connection and the heat sink. If the tab is live and the heat sink is shared or grounded, an insulation pad and bushing may be required. It also helps avoid a pinout problem after samples arrive.

What data helps quote TO-220 HV diodes?

Send voltage, current, recovery need, pinout, tab type, heat-sink method, old marking and quantity. A board or heat-sink photo helps confirm mechanical clearance. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Can TO-220 replace DO-201AD?

Only if the board and mechanical assembly can support the tab-mounted package. TO-220 may improve heat handling, but it changes pinout, height, mounting and insulation needs. It also helps avoid a pinout problem after samples arrive. That keeps the tab-mounted choice tied to thermal reality.

When should I use MUR-type parts?

Use MUR-type directions when ultrafast recovery and power-package thermal handling are needed. Confirm exact voltage, current, package and pinout before approving them as equivalents. That keeps the tab-mounted choice tied to thermal reality. It also helps avoid a pinout problem after samples arrive.

Can Lian Tuo support TO-220 equivalents?

Yes. We can compare MUR, FES, dual and single TO-220 high voltage diode options by voltage, recovery, pinout, tab style and mounting needs. It also helps avoid a pinout problem after samples arrive. That keeps the tab-mounted choice tied to thermal reality.
