Frequently Asked Questions
What are the key voltage and current ratings of the STPST5H100SF Schottky rectifier?
The STPST5H100SF is rated for a 100 V reverse voltage and a 5 A forward current, with a maximum forward voltage of 0.68 V at rated current. These specifications make it suitable for medium-power rectification and freewheeling diode roles in switch-mode power supplies operating up to 100 V DC bus.
How does the TO-277A package of the STPST5H100SF benefit compact power supply PCB designs?
The TO-277A is a 3-pin surface mount package with a small footprint, enabling high-power-density PCB layouts. It supports direct SMT mounting for automated assembly, reduces parasitic inductance compared to leaded packages, and delivers improved thermal performance for 5 A continuous operation in limited board space.
In which power conversion topologies is the STPST5H100SF typically used as a freewheeling diode?
The STPST5H100SF is used as a freewheeling diode in flyback, buck-boost, and boost converters operating at up to 100 V, where its 5 A rating and 0.68 V low forward drop minimize energy loss during switching transitions. Motor drives and battery chargers also rely on this part to clamp inductive kickback and protect switching transistors.
What is the lead time for STPST5H100SF, and are alternatives available for shorter delivery?
The STPST5H100SF has a factory lead time of approximately 19 weeks when ordered directly from STMicroelectronics. For shorter delivery, distributors may carry stock, and comparable 100 V / 5 A single Schottky rectifiers in TO-277A packages from other STMicro series or similar manufacturers can serve as drop-in alternatives during supply constraints.
