STMicroelectronics STPS10H60SFY

Overview

STPS10H60SFY from STMicroelectronics is an AEC-Q101-qualified automotive power Schottky rectifier in PSMC (TO-277A) package, rated for 10 A average forward current, 60 V repetitive peak reverse voltage, and 175 °C maximum junction temperature. It delivers low typical forward voltage (0.53 V at 10 A, 125 °C), negligible switching losses, and avalanche capability-used in DC/DC converters and reverse polarity protection circuits.

For engineers reviewing the STPS10H60SFY datasheet, STPS10H60SFY pinout, STPS10H60SFY application, or STPS10H60SFY equivalent, key selection criteria include its wettable flanks for automated optical inspection, -40 °C to +175 °C VRRM guarantee, 2.4 °C/W junction-to-case thermal resistance, and ECOPACK®2 compliance for automotive-grade reliability.

Technical Context

This Schottky rectifier uses a planar metal-silicon junction optimized for low conduction loss and high-temperature operation. Its static characteristics are specified across -40 °C to +175 °C, with reverse leakage limited to 10 mA at 125 °C and VR = VRRM, and forward voltage tightly controlled (0.515–0.58 V at 5 A, 125 °C).

The device features avalanche-rated capability (145 W, 10 µs pulse, Tj = 125 °C) and thermal design support via documented Rth(j-c) = 2.4 °C/W and derating curves for junction-to-ambient resistance versus copper area-enabling robust thermal management in compact automotive power stages.

Key Specifications

FAQ

Is STPS10H60SFY suitable for synchronous rectification?

No. STPS10H60SFY is a passive Schottky rectifier-not a MOSFET-based synchronous rectifier IC. It lacks gate drive interface, control logic, or integrated drivers. Its role is strictly uncontrolled freewheeling or polarity protection; synchronous replacement requires active switching devices like ST's STL12DN6LF7.

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

The datasheet specifies IF(AV) = 10 A at Tc = 140 °C with duty cycle δ = 0.5. At Tc > 140 °C, derating is required per Figure 1. For continuous DC operation (δ = 1), maximum sustainable case temperature is approximately 115 °C to maintain 10 A average current within safe SOA limits.

Does STPS10H60SFY require a heatsink in typical automotive applications?

Yes-when operating near rated 10 A current, especially at elevated ambient temperatures. With Rth(j-c) = 2.4 °C/W and typical conduction loss ~5.3 W at 10 A/125 °C, a minimum 25 cm² copper pour (per Figure 7) or bolted heatsink is required to hold Tj ≤ 175 °C under worst-case 85 °C ambient conditions.

Can STPS10H60SFY replace a standard silicon PN diode in an existing design?

Yes-with verification of reverse voltage margin and layout thermal capacity. Its 60 V VRRM matches many 100 V Si diodes' practical blocking capability, but lower VF reduces heat generation. However, higher IR at elevated temperature must be checked in reverse-biased standby modes to avoid leakage-induced power loss.
