Key Features
- Automotive-qualified 60 V dual 2x3 A Schottky rectifier with 175°C max junction temperature for under-hood reliability
- 0.50 V typical (0.74 V max) forward voltage minimizes conduction losses in high-current rectification
- Common-cathode dual configuration enables compact full-wave or center-tap rectifier circuits
- Freewheeling diode function protects inductive loads in motor drivers and relay switching circuits
- AEC-Q101 compatible construction supporting automotive power supply and drive module designs
Applications
The STPS660CSFY is used in automotive power management modules, DC-DC converters, and motor drive circuits where a high-temperature Schottky rectifier with low forward voltage is required for efficient power conversion. Its common-cathode dual configuration makes it ideal for synchronous rectification in boost or SEPIC converters in 12 V automotive electrical systems. The device also serves as a freewheeling diode in relay drivers and brush-motor H-bridges, where fast reverse recovery and low forward drop reduce switching losses and component stress.

Frequently Asked Questions
What is the forward voltage of STPS660CSFY and how does it compare to standard silicon rectifiers?
The STPS660CSFY has a typical forward voltage of 0.50 V and a maximum of 0.74 V at rated current, significantly lower than standard silicon PN rectifiers which typically exhibit 0.8 V to 1.1 V forward drop. This 300 mV to 600 mV reduction translates directly into lower conduction losses in automotive rectifier stages operating at 3 A per element.
Why is the 175°C maximum junction temperature important for automotive under-hood applications?
Under-hood automotive environments can see ambient temperatures of 105°C to 125°C during engine operation. A 175°C maximum junction temperature allows the STPS660CSFY to sustain rated 2x3 A current even with elevated ambient temperatures and modest PCB thermal resistance, without derating the current below useful operating levels in motor control modules or alternator rectifiers.
How does the common-cathode dual configuration of STPS660CSFY benefit rectifier circuit design?
The common-cathode configuration places both Schottky anodes in a single package with a shared cathode output, enabling a center-tap full-wave rectifier using just this one device. This reduces the component count from 2 separate diodes to 1 IC, saves PCB area, and simplifies the thermal management since both 3 A elements share a common case thermal path, reducing junction-to-ambient resistance by approximately 40% versus two discrete diodes.
For how long is STPS660CSFY expected to remain in production and what lead time should buyers plan for?
The STPS660CSFY was introduced in October 2020 and carries a YTEOL of approximately 6.22 years from introduction, suggesting availability through the mid-2020s. Factory lead time is 15 weeks, which is longer than typical commodity components, so automotive Tier 1 suppliers and contract manufacturers should maintain safety stock of at least 20 weeks of demand to buffer against supply disruptions.
