Key Features
- 100 V reverse voltage rating with 2 A continuous forward current supports a wide range of switch-mode power supply and freewheeling rectifier designs
- Schottky trench silicon technology achieves a low maximum forward voltage of 0.805 V, minimizing conduction losses in DC-DC converters and output rectifier stages
- Non-repetitive peak forward current capability of 35 A provides robust surge tolerance to protect power circuits during transient load events
Applications
The STPST2H100ZF is used in switch-mode power supply output rectifiers, DC-DC buck and boost converter freewheeling diode positions, and battery charger circuits where 100 V reverse blocking and low 0.805 V forward drop are needed at up to 2 A continuous current. Its flat-lead SOD package suits compact SMT power board designs in consumer electronics, industrial power modules, and LED driver applications.

Frequently Asked Questions
What is the reverse voltage and continuous forward current rating of the STPST2H100ZF?
The STPST2H100ZF is rated for 100 V reverse blocking voltage and 2 A continuous forward current, with a maximum forward voltage drop of 0.805 V at rated current, making it a low-loss Schottky rectifier for power supply output stages and freewheeling diode applications.
How does the STPST2H100ZF's 35 A peak current rating protect power circuits during transients?
The STPST2H100ZF supports a non-repetitive peak forward current of 35 A, which is 17.5 times its 2 A continuous rating, giving it strong surge robustness to survive inrush current events during power-up or load transients in 100 V switch-mode power supply and motor drive freewheeling diode circuits without permanent damage.
What circuit positions in a DC-DC converter benefit most from using the STPST2H100ZF as a freewheeling diode?
The STPST2H100ZF is best placed in the freewheeling (flyback) diode position of boost converters, synchronous buck converters without full synchronous rectification, and flyback SMPS secondary-side rectifiers operating below 100 V, where its 0.805 V forward drop and fast Schottky switching speed reduce both conduction and switching losses compared to a standard PN silicon rectifier diode.
