STMicroelectronics STPS10200SF

Overview

STPS10200SF from STMicroelectronics is a 10 A, 200 V Schottky power rectifier in PSMC (TO-277A) package, designed for high-efficiency secondary-side rectification and freewheeling in LED lighting, telecom standby, and server auxiliary supplies. It delivers 0.660 V typical forward voltage at 10 A/125 °C, supports 175 °C maximum junction temperature, and features wettable flanks for automated optical inspection.

For engineers reviewing the STPS10200SF datasheet, STPS10200SF pinout, STPS10200SF application, or STPS10200SF equivalent, key selection criteria include conduction loss optimization (P = 0.60 × IF(AV) + 0.013 × IF²(RMS)), thermal resistance (Rth(j-c) = 0.84 °C/W), reverse leakage (<4 mA at 125 °C), and compatibility with compact, low-profile PCB layouts requiring <1.1 mm height.

Technical Context

This Schottky diode operates without minority-carrier storage, enabling zero reverse recovery time and eliminating switching losses in high-frequency DC/DC converters. Its metal–semiconductor junction enables low VF and high Tj capability, while the PSMC package's copper-tab construction ensures efficient conduction cooling.

The device is rated for 210 A non-repetitive surge current (10 ms sine), supports continuous operation up to 160 °C case temperature at full 10 A average current, and exhibits <6 µA reverse leakage at 25 °C - critical for maintaining efficiency in low-power standby rails.

Key Specifications

Pinout & Package

STPS10200SF uses the PSMC (TO-277A) surface-mount package: flat, low-profile (1.1 mm typical height), with exposed copper thermal pad on the bottom side and wettable flank edges for AOI. The package has two terminals: anode and cathode, mounted on a single-sided PCB layout with thermal relief to internal ground or power planes.

FAQ

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

The datasheet specifies IF(AV) = 10 A at Tc = 160 °C under δ = 0.5 square wave conditions. Operation above this case temperature requires current derating per Figure 1. At Tc = 175 °C, the device supports approximately 7.5 A average current. Thermal design must ensure the tab remains below 160 °C under worst-case ambient and airflow conditions.

Does STPS10200SF require a heatsink for 10 A operation?

No dedicated heatsink is required if the PSMC package's copper tab is soldered to ≥4 cm² of 70 µm-thick FR4 copper (per Figure 6). With that layout, Rth(j-a) drops to ~4.5 °C/W, allowing 10 A operation at 25 °C ambient with ~30 °C temperature rise. Smaller copper areas necessitate derating or forced air.

Can STPS10200SF replace a standard PN-junction rectifier in an existing design?

Yes - as a direct drop-in replacement in most cases due to identical PSMC footprint and pinout. However, its lower VF reduces forward conduction loss but increases reverse leakage (up to 4 mA at 125 °C), which may affect light-load efficiency in ultra-low-power standby rails.

Is STPS10200SF suitable for reverse battery protection in automotive applications?

Yes - when configured cathode-to-battery-anode, it blocks reverse current up to 200 V. Its 175 °C Tj rating supports under-hood environments, and 210 A IFSM handles jump-start surges. However, transient voltage suppression beyond 200 V still requires external TVS devices per ISO 7637-2.
