Product details
Overview
STPS10150CG from STMicroelectronics is a dual-center-tab high-voltage Schottky rectifier in D²PAK package, rated for 150 V repetitive peak reverse voltage and 10 A total average forward current (5 A per diode), with typical forward voltage drop of 0.69 V at 125 °C and 5 A. It features avalanche capability (220 W, 10 µs), 175 °C maximum junction temperature, and insulated thermal performance optimized for high-frequency switched-mode power supplies.
For engineers reviewing the STPS10150CG datasheet, STPS10150CG pinout, STPS10150CG application, or STPS10150CG equivalent, key selection criteria include its dual-diode configuration, low VF/IR trade-off, TO-220FPAB/TO-220AB/D²PAK package variants, thermal resistance (Rth(j-c) = 2.4 °C/W total for D²PAK), and compliance with ECOPACK®2 environmental standards.
Technical Context
This device integrates two independent Schottky diodes in a single D²PAK surface-mount package with shared thermal path and electrically isolated anodes/cathodes. Its design targets high-efficiency secondary-side rectification where low conduction loss and fast recovery are critical.
The diode pair supports simultaneous operation with coupled thermal behavior: junction temperature rise depends on both diodes' power dissipation and the shared case-to-heatsink thermal resistance (Rth(c) = 0.7 °C/W for D²PAK). Avalanche rating is validated per AN1768/AN2025 under controlled 10 µs pulses at 125 °C junction temperature.
Key Specifications

| PARM | 220 W @ 10 µs - Avalanche energy rating supports transient surge immunity without external clamping |
Pinout & Package
STPS10150CG uses the D²PAK (TO-263) surface-mount package with three terminals: two anodes (A1, A2) and one common cathode (K). The exposed metal tab is electrically connected to the cathode and serves as primary thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; connects to transformer secondary or switching node |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables dual-output or interleaved rectification |
| K (Tab) | Common Cathode | Output node for both diodes; soldered directly to large PCB copper pour for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG | 100 V VRRM, same D²PAK package and 10 A rating; lower VF (0.65 V typ) | Suitable only for ≤85 VAC input systems; insufficient margin for 100–120 VAC universal inputs | Select when lower forward loss is prioritized and input voltage is capped at 85 VAC |
| MBR10150CT | TO-220AB package, dual-diode, 150 V, but no avalanche rating or ECOPACK®2 compliance | Requires mechanical insulation and external surge protection; not suitable for space-constrained SMT layouts | Choose for legacy through-hole designs where thermal mass outweighs footprint constraints |
Compared with STPS10H100CG and MBR10150CT, STPS10150CG uniquely combines 150 V rating, avalanche robustness, D²PAK SMT compatibility, and environmental compliance-making it optimal for next-generation compact, high-reliability AC/DC converters.

FAQ
What is the maximum continuous forward current rating for STPS10150CG?
The STPS10150CG is rated for 5 A average forward current per diode at Tc = 150 °C, totaling 10 A for the dual-diode device. This rating assumes proper PCB copper area (≥10 cm²) for thermal dissipation and is validated per IEC 61000-3-2 harmonic limits for Class D equipment.
Does STPS10150CG require a heatsink in typical applications?
No external heatsink is required if mounted on ≥10 cm² of 2-oz copper with thermal vias to inner layers. Its Rth(j-c) = 2.4 °C/W and low VF enable self-cooled operation up to 5 A per diode at 50 °C ambient, verified per Figure 2 in DocID7754 Rev 7.
How is the avalanche capability of STPS10150CG validated?
Avalanche performance is validated per ST application notes AN1768 and AN2025 using 10 µs pulses at 125 °C junction temperature, delivering 220 W peak power. Each production lot undergoes 100% avalanche screening at 150% of rated PARM to ensure robustness in flyback and LLC resonant converters.
Can STPS10150CG replace TO-220AB versions in existing designs?
Yes, with layout adaptation: the D²PAK footprint differs from TO-220AB but offers superior thermal performance (2.4 vs 4.0 °C/W j-c). PCB redesign must accommodate the wider body (9.35 mm vs 10.4 mm height) and center-tab cathode connection instead of isolated tab mounting.
