STMicroelectronics STPS10H60SF

Overview

STPS10H60SF from STMicroelectronics is a 60 V, 10 A average forward current Schottky barrier rectifier in PSMC (TO-277A) package, optimized for high-frequency DC/DC converters and reverse battery protection. It delivers low forward voltage drop (0.60 V typ. at 5 A, 25 °C), supports 175 °C maximum junction temperature, and features wettable flanks for automated optical inspection.

For engineers reviewing the STPS10H60SF datasheet, STPS10H60SF pinout, STPS10H60SF application, or STPS10H60SF equivalent, key selection criteria include conduction loss modeling (P = 0.49 × IF(AV) + 0.018 × IF²(RMS)), avalanche power rating (145 W at 10 µs), thermal resistance (Rth(j-c) = 2.4 °C/W), and leakage performance (≤10 mA at 125 °C, VR = VRRM).

Technical Context

This Schottky rectifier uses a planar silicon structure with metal–semiconductor junction to minimize forward voltage and switching losses. Its low VF and fast recovery enable high-efficiency operation in compact 1.1 mm profile adapters and battery chargers where thermal management is constrained.

The device is rated for repetitive peak reverse voltage of 60 V and surge non-repetitive forward current up to 210 A (10 ms sinusoidal). Its avalanche capability (145 W, 10 µs pulse) and Tj(max) = 175 °C support robust operation under transient overloads and elevated ambient conditions.

FAQ

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

The datasheet specifies IF(AV) = 10 A at Tc = 140 °C. Operation above this case temperature requires derating per Figure 1. At Tc = 150 °C, average current drops to ~8.5 A; at 160 °C, it falls to ~6.5 A. Thermal design must maintain Tc ≤ 140 °C under worst-case load and ambient conditions.

Does STPS10H60SF support synchronous rectification drive?

No. STPS10H60SF is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It operates unidirectionally with fixed anode–cathode polarity and does not accept gate signals or timing inputs.

How is the avalanche rating validated in system-level testing?

The 145 W avalanche power rating is measured under controlled 10 µs pulses at Tj = 125 °C (Table 1). System validation requires replicating worst-case inductive energy dump (e.g., transformer leakage in flyback) using pulse generators and verifying no parameter shift after 1000+ cycles per JEDEC JESD22-A106.

Can STPS10H60SF replace a standard PN junction diode in existing designs?

Yes-if reverse voltage stays ≤60 V and layout accommodates the PSMC footprint. Benefits include lower VF (reducing conduction loss by ~30–40%), faster switching (no reverse recovery), and higher Tj tolerance. However, reverse leakage is higher than PN diodes, so verify standby current impact in battery-critical applications.
