Key Features
- 100 V reverse voltage with 5 A average forward current rating for medium-power rectification in switch-mode power supplies
- Ultra-low forward voltage drop of 0.68 V max reduces conduction losses and improves efficiency in free-wheeling diode applications
- Non-repetitive peak forward current of 75 A provides high surge tolerance for inrush protection in motor drive and inverter circuits
Applications
The STPST5H100AF is optimized as a free-wheeling diode in DC-DC converters, synchronous rectifiers, and H-bridge motor drive circuits operating up to 100 V. Its low forward voltage drop of 0.68 V minimizes conduction losses in PFC stages, boost converters, and UPS systems where efficiency is critical. The compact flat-lead SMD package enables dense power stage layouts in industrial power supplies and battery chargers.

Frequently Asked Questions
What is the forward voltage drop of the STPST5H100AF and how does it compare to standard PN junction diodes in free-wheeling applications?
The STPST5H100AF has a maximum forward voltage drop of 0.68 V at 5 A, significantly lower than standard silicon PN junction diodes which typically drop 0.9 V to 1.1 V under similar conditions. This 30-40% reduction in conduction loss translates directly to higher efficiency in free-wheeling diode positions within boost converters and motor H-bridges operating at 100 V.
What surge current capability does the STPST5H100AF offer for motor drive inrush protection?
The STPST5H100AF is rated for a non-repetitive peak forward current of 75 A, which is 15 times its 5 A continuous rating. This high surge tolerance allows the diode to safely conduct motor startup inrush currents and capacitive charging pulses without thermal runaway, making it suitable for 24 V to 100 V motor drive and inverter free-wheeling positions.
When should an engineer choose the STPST5H100AF over a standard silicon rectifier in a 100 V power supply design?
The STPST5H100AF is preferred over standard silicon rectifiers when power supply efficiency above 90% is required, since its 0.68 V forward voltage is roughly half the 1.0 V drop of conventional diodes at 5 A. The Schottky trench construction also provides faster switching recovery compared to PN diodes, reducing switching losses in designs operating at frequencies above 100 kHz.
