STMicroelectronics STPS16H100CG

Overview

STPS16H100CG from STMicroelectronics is a dual-center-tap high-voltage Schottky rectifier in D²PAK package, rated for 100 V repetitive reverse voltage and 16 A total average forward current (8 A per diode), with typical forward voltage drop of 0.59 V at 125 °C and 8 A. It delivers negligible switching losses and avalanche capability up to 625 W, designed for high-frequency DC-DC converters in industrial power adapters.

For engineers reviewing the STPS16H100CG datasheet, STPS16H100CG pinout, STPS16H100CG application, or STPS16H100CG equivalent, this device supports thermal design with validated junction-to-case resistance (1.6 °C/W per diode), low leakage (<3.6 µA at 25 °C), and ECOPACK®2-compliant packaging for regulated environments.

Technical Context

This dual-diode Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap configuration), enabling synchronous rectification in half-bridge or center-tapped transformer topologies. Its low VF–IR trade-off targets efficiency-critical 100 kHz–1 MHz SMPS designs where conduction loss dominates.

Thermal management is defined by separate junction-to-case (1.6 °C/W per diode) and coupling (0.6 °C/W) resistances - critical when both diodes operate simultaneously. Avalanche rating (625 W, 10 µs pulse, Tj = 125 °C) enables robustness against inductive turn-off transients without external snubbers.

Key Specifications

Pinout & Package

The STPS16H100CG uses the D²PAK (TO-263-3L) surface-mount package with exposed metal tab for thermal conduction. Pin assignment is verified per ST's official package drawing (DocID8734 Rev 3, Fig.9): three terminals - two anodes (A1, A2) and one shared cathode (K).

FAQ

What is the thermal resistance from junction to case for each diode in STPS16H100CG?

The junction-to-case thermal resistance is 1.6 °C/W per diode, measured with the device mounted on a standard heatsink. When both diodes conduct simultaneously, the total thermal path includes coupling resistance (0.6 °C/W), resulting in a combined thermal impedance that must be calculated using ST's provided formula: ΔTj(diode 1) = P(diode1) × 1.6 + P(diode 2) × 0.6.

Does STPS16H100CG support center-tapped transformer configurations?

Yes - STPS16H100CG is explicitly designed as a dual-center-tap Schottky rectifier with two independent anodes (A1, A2) and one common cathode (K). This configuration directly supports center-tapped forward, push-pull, and half-bridge secondary rectification topologies without external interconnection.

Is STPS16H100CG compliant with RoHS and halogen-free requirements?

Yes - STPS16H100CG is ECOPACK®2 certified, meeting RoHS Directive 2011/65/EU and IEC 61249-2-21 for halogen-free materials. The epoxy mold compound achieves UL 94 V0 flammability rating, and all plating and terminations comply with JEDEC J-STD-609 Class 1 moisture sensitivity level.

What is the maximum surge current rating for STPS16H100CG?

The non-repetitive surge forward current (IFSM) is 200 A for a 10 ms sinusoidal pulse at 25 °C. This rating applies per diode and assumes proper thermal mounting; repeated surges require adherence to the thermal derating curve in Figure 3 of the datasheet (DocID8734 Rev 3) to avoid junction overheating.
