Frequently Asked Questions
What are the key electrical ratings of the STPS15L45CB rectifier?
The STPS15L45CB is rated for a 45 V maximum reverse voltage and a 15 A average output current across both Schottky elements. The maximum forward voltage drop is 0.64 V at rated current, which is significantly lower than standard PN junction diodes, reducing power dissipation in the rectifier stage.
How does the common-cathode dual configuration benefit full-bridge power converter designs?
The common-cathode arrangement of the two Schottky elements in the STPS15L45CB allows both anodes to be driven independently while sharing a single heatsink pad connected to the cathode. This reduces PCB trace complexity in full-bridge rectifiers and freewheeling circuits by at least 2 external connections, and both elements fit within the TO-252AA footprint.
For which switching frequencies is the STPS15L45CB suitable as a freewheeling diode?
As a Schottky rectifier, the STPS15L45CB has negligible reverse recovery time compared to standard fast-recovery diodes, making it suitable for switching frequencies from 100 kHz up to several hundred kHz in buck, boost, and flyback converter topologies operating at 45 V or below.
