Key Features
- 100 V reverse voltage and 15 A forward current rating in a compact D2PAK surface mount package
- Ultra-low forward voltage of 0.74 V (max) achieved through advanced Schottky Trench technology, reducing conduction losses
- Optimized as a freewheeling diode for switching power supplies, motor drives, and DC-DC converters
Applications
The STPST15H100SB-TR is well-suited for use as a freewheeling diode in synchronous buck and boost DC-DC converters operating up to 100 V, where its low 0.74 V forward voltage reduces power dissipation at 15 A loads. It is also used in motor drive circuits, PFC boost stages, and industrial power supplies where efficient rectification and fast recovery are critical. The D2PAK through-hole-like thermal pad enables excellent heat dissipation in high-current applications without requiring additional heatsinking.

Frequently Asked Questions
What are the key electrical ratings of the STPST15H100SB-TR?
The STPST15H100SB-TR is rated for a 100 V reverse blocking voltage and a 15 A average forward current, with a maximum forward voltage drop of 0.74 V at rated current. These ratings make it suitable for medium-power freewheeling and rectification stages in switch-mode power supplies.
How does the Schottky Trench structure of STPST15H100SB-TR compare to standard planar Schottky diodes?
The trench gate structure reduces on-state resistance and forward voltage compared to conventional planar Schottky diodes, achieving VF as low as 0.74 V at 15 A. This translates to measurably lower conduction losses in continuous current mode DC-DC converters running at switching frequencies above 100 kHz.
For which converter topologies is the STPST15H100SB-TR best suited as a freewheeling element?
The STPST15H100SB-TR is optimized as a free-wheeling diode in non-isolated buck, boost, and buck-boost topologies operating up to 100 V with output currents up to 15 A. The D2PAK package's exposed drain pad also helps manage junction temperatures below 150°C in continuous conduction mode.
What package does the STPST15H100SB-TR use and how does it affect PCB thermal management?
The D2PAK (TO-263) surface mount package provides a large exposed copper pad on the bottom, enabling direct thermal coupling to a PCB copper pour or heatsink slug. This allows the device to dissipate sufficient power at 15 A without an external clip heatsink when a 2-oz copper plane of at least 6 cm² is used.
