STMicroelectronics STPS10M60SF

Overview

STPS10M60SF from STMicroelectronics is a 60 V, 10 A average forward current Schottky barrier rectifier in PSMC (TO-277A) package, featuring 0.53 V typical forward voltage at 10 A and 125 °C, 175 °C maximum junction temperature, and avalanche capability for robust reverse-battery protection in compact DC/DC converters.

For engineers reviewing the STPS10M60SF datasheet, STPS10M60SF pinout, STPS10M60SF application, or STPS10M60SF equivalent, key selection criteria include low-profile thermal performance (2 °C/W R_th(j-c)), wettable flanks for automated optical inspection, and conduction loss modeling via P = 0.38 × I_F(AV) + 0.022 × I_F(RMS)².

Technical Context

This Schottky rectifier uses a planar metal-silicon junction optimized for high-frequency switching (e.g., >100 kHz DC/DC topologies), with low Q_rr and negligible reverse recovery charge-enabling reduced EMI and higher efficiency than fast recovery diodes. Its 175 °C T_j(max) rating supports operation in thermally constrained spaces like notebook adapters.

The PSMC (TO-277A) package delivers 2 °C/W junction-to-case thermal resistance and enables direct PCB copper pad conduction cooling. Avalanche energy rating of 258 W (10 µs pulse, 125 °C) provides transient overvoltage resilience without external snubbers in battery protection circuits.

Key Specifications

Pinout & Package

STPS10M60SF is housed in the PSMC (TO-277A) surface-mount package: ultra-low profile (1.1 mm typ.), wettable flanks, epoxy UL94-V0 rated, with thermal pad on cathode side for conduction cooling.

FAQ

What is the maximum allowable case temperature for continuous 10 A operation?

The datasheet specifies I_F(AV) = 10 A at T_c = 145 °C under δ = 0.5 square pulse conditions. Operation above this case temperature requires derating per Figure 1; at 155 °C case, average current drops to ~8.5 A. Thermal design must ensure copper pad and airflow keep T_c ≤145 °C for full-rated performance.

Does STPS10M60SF require a heatsink for 10 A operation?

No discrete heatsink is required. The PSMC package achieves 2 °C/W R_th(j-c) when soldered to ≥4 cm² of 35 µm copper on FR4. For 10 A at 125 °C junction, case temperature stays ≤145 °C with that copper area-enabling fully passive thermal management in most adapter and charger layouts.

Is STPS10M60SF suitable for reverse battery protection in automotive applications?

Yes-it supports reverse polarity up to –60 V and features 258 W avalanche capability at 125 °C, meeting ISO 7637-2 pulse 1 and pulse 4a requirements when properly mounted. However, its 175 °C T_j(max) exceeds AEC-Q101 temperature limits; qualification for automotive use requires system-level validation per OEM stress profiles.

How does the wettable flank design impact assembly yield?

The 0.23 mm vertical flank height and defined solder meniscus geometry enable 100% automated optical inspection (AOI) of solder joint quality on standard SMT lines. This eliminates manual visual checks and reduces field failure risk in high-volume consumer power supplies where solder voiding or insufficient wetting could cause thermal runaway.
