Product Description
This SF24 super fast recovery diode page is for compact boards that need 2A, 400V class fast rectification in a DO-15 axial package. You can compare SF24 by reverse voltage, current, recovery behavior, surge rating, forward drop, lead pitch, body length and operating temperature. It is useful in LED drivers, small chargers, auxiliary supplies and converter boards where DO-201AD packages take too much space. Lian Tuo helps you confirm whether SF24 gives enough current and voltage margin before sampling. That keeps the SF24 choice tied to compact DO-15 boards.

Fit Speed Into Less Space
An SF24 super fast recovery diode is useful when the circuit needs fast recovery but cannot spare space for a DO-201AD body. The DO-15 package suits slimmer boards. Check load current, lead pitch and temperature so the compact package stays realistic. It also helps avoid using a larger body than the board needs.
Check The 2A Duty
SF24 should be selected when 2A class current is enough for the application. A board with repeated surge or higher continuous current may need a larger package. The SF24 super fast recovery diode should be reviewed against real duty before replacement approval. That keeps the SF24 choice tied to compact DO-15 boards.
Use 400V With Care
The 400V class should match the circuit peak reverse stress and switching spikes. An SF24 super fast recovery diode can be a good compact choice, but only when the voltage margin fits the waveform. Nearby SF voltage classes can be compared if needed. It also helps avoid using a larger body than the board needs.
Keep Repair Stock Consistent
Service teams often mix 2A and 3A SF series parts because names look similar. Lian Tuo can compare SF24 super fast recovery diode package, current class and voltage rating so repair stock does not create hidden changes. That keeps the SF24 choice tied to compact DO-15 boards. It also helps avoid using a larger body than the board needs.
Vertical Product Applications
Compact LED Drivers
Use an SF24 super fast recovery diode in compact LED drivers when DO-15 body size and fast recovery fit the board. The selected part should match output current, voltage margin and housing temperature. It also helps avoid using a larger body than the board needs. That keeps the SF24 choice tied to compact DO-15 boards.
Small Charger Circuits
Small charger circuits can use SF24 when 2A current class and faster turn-off are enough. You should check startup surge, board airflow and lead spacing before approving samples. That keeps the SF24 choice tied to compact DO-15 boards. It also helps avoid using a larger body than the board needs.
Auxiliary Supply Repair
Auxiliary supply repairs need package-compatible replacements. An SF24 super fast recovery diode should be checked against old body size, marking and circuit waveform before it enters service stock. It also helps avoid using a larger body than the board needs. That keeps the SF24 choice tied to compact DO-15 boards.
FAQ
What is SF24 super fast recovery diode used for?
It is used in 2A, 400V class fast rectifier positions where a compact DO-15 axial package is preferred. Typical uses include LED drivers, chargers and auxiliary supplies. It also helps avoid using a larger body than the board needs. That keeps the SF24 choice tied to compact DO-15 boards.
Can SF24 replace SF34?
Only if the circuit current and package needs fit the 2A DO-15 class. SF34 is larger and commonly 3A class, so the substitution should be reviewed carefully. That keeps the SF24 choice tied to compact DO-15 boards. It also helps avoid using a larger body than the board needs.
What data helps quote SF24?
Send voltage, current, recovery need, package, surge condition, old marking and quantity. A board photo helps confirm DO-15 body length and lead pitch. It also helps avoid using a larger body than the board needs. That keeps the SF24 choice tied to compact DO-15 boards.
Is SF24 suitable for SMPS circuits?
It can be suitable in selected SMPS or auxiliary converter positions when recovery speed, voltage, current and temperature fit the waveform. High-stress nodes should be reviewed. That keeps the SF24 choice tied to compact DO-15 boards. It also helps avoid using a larger body than the board needs.
Can a standard DO-15 diode replace SF24?
Only in low-speed positions where recovery speed is not important. If the circuit needs super-fast behavior, a standard recovery replacement may increase heat or noise. It also helps avoid using a larger body than the board needs. That keeps the SF24 choice tied to compact DO-15 boards.
When should I choose SF26 instead?
Choose SF26 or another higher-voltage SF model when the 400V class does not leave enough reverse-voltage margin for your circuit spikes or tolerance. That keeps the SF24 choice tied to compact DO-15 boards. It also helps avoid using a larger body than the board needs.
Can Lian Tuo support SF24 equivalents?
Yes. We can compare SF24, nearby SF series and 2A super fast recovery diode equivalents by voltage, package, recovery and current duty. It also helps avoid using a larger body than the board needs. That keeps the SF24 choice tied to compact DO-15 boards.
