- Silicon Schottky junction for fast switching and minimal reverse recovery charge
- Lead-free (Pb-free) construction meeting RoHS environmental compliance
Applications
The STPS660CB is commonly used in switch-mode power supply output stages as a dual Schottky output rectifier, reducing conduction losses thanks to its low 0.59 V forward voltage drop at 3 A. In DC-DC converters for industrial and consumer electronics, its common-cathode configuration simplifies both full-wave rectification and load-OR redundancy circuits with fewer external components. The D-PAK package provides a robust surface-mount footprint with good thermal dissipation, making it suitable for buck converter synchronous rectification and flyback secondary rectification in compact power designs.

Frequently Asked Questions
What forward voltage drop does the STPS660CB exhibit at its rated 3 A current?
The STPS660CB has a maximum forward voltage of 0.59 V at 3 A per element, significantly lower than a standard silicon PN diode at about 0.7 V, reducing rectification losses in 60 V power supply designs by roughly 15% per stage.
Why is the common-cathode configuration of the STPS660CB useful in power supply designs?
The common-cathode arrangement connects both anodes to separate inputs and shares one cathode output, enabling full-wave center-tap rectification or power supply OR-ing from 2 sources with a single 3-pin D-PAK component instead of 2 separate diodes.
In what thermal conditions can the STPS660CB operate reliably?
The STPS660CB is rated for junction temperatures up to +150°C and storage temperatures from -65°C to +175°C; the exposed D-PAK pad allows heat spreading to the PCB copper, maintaining 3 A continuous operation in ambient temperatures up to +85°C with adequate copper area.
How does the STPS660CB compare to a standard silicon rectifier for flyback converter secondary circuits?
Compared to a standard 1N540x silicon diode, the STPS660CB offers lower forward voltage (0.59 V vs. ~1 V) and virtually no reverse recovery time, reducing switching losses at 100 kHz+ frequencies and improving overall flyback converter efficiency by 2 to 5 percentage points.
