Frequently Asked Questions
What are the voltage and current ratings of the STPST3H100AF?
The STPST3H100AF is rated for a maximum reverse voltage of 100 V and a continuous forward current of 3 A. Its maximum forward voltage is 0.755 V at rated current, giving it low conduction losses compared to standard PN junction rectifiers in the same voltage class.
Why is the STPST3H100AF well-suited as a freewheeling diode in switching power supplies?
As a Schottky trench rectifier, the STPST3H100AF features extremely fast reverse recovery and a low forward voltage of 0.755 V, which reduces energy loss during the freewheeling phase in buck converters and motor drive circuits. Its 100 V blocking capability provides adequate margin for 48 V bus and 24 V rail designs.
What PCB footprint does the STPST3H100AF use, and how does it compare to larger SMC packages?
The STPST3H100AF uses a Small Outline Diode Flat Lead (SODF) package, which is smaller than SMC and SMB packages, making it suitable for space-constrained designs. Despite its compact 2-pin surface mount footprint, it handles 3 A continuous current and dissipates heat efficiently through the PCB copper pads.
