Product details
Overview
STPS30150CG from STMicroelectronics is a dual-center-tap high-voltage Schottky rectifier in D²PAK (TO-263) package, rated for 150 V reverse voltage and 2 × 15 A average forward current per diode at TC = 120 °C. It delivers low forward voltage drop (0.69 V typ. at 15 A, 125 °C), low leakage (8.0 mA max at 125 °C), and avalanche-rated power (750 W, 10 µs pulse), optimized for high-frequency switch-mode power supplies in industrial AC/DC adapters and server PSUs.
For engineers reviewing the STPS30150CG datasheet, STPS30150CG pinout, STPS30150CG application, or STPS30150CG equivalent, key selection criteria include thermal resistance junction-to-case (0.85 °C/W total), insulated package compliance (ECOPACK®2), dual-diode center-tap configuration, and conduction loss model (P = 0.64 × IF(AV) + 0.0073 × IF²(RMS)).
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap topology), enabling synchronous rectification in full-wave bridge or center-tapped transformer configurations. Its low VF and high Tj(max) = 175 °C support high-efficiency, high-power-density designs where thermal management is constrained.
The device features specified avalanche capability (PARM = 750 W, tp = 10 µs), validated under controlled transient conditions, and exhibits Rth(j-c) = 0.85 °C/W (total device) in D²PAK - critical for predicting junction temperature rise under continuous conduction mode operation in 100–500 kHz SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per diode; defines usable input voltage range in offline SMPS. |
| IF(AV) per diode | 15 A at TC = 120 °C - Continuous DC current handling per diode path; sets minimum heatsink sizing for 30 A total output. |
| VF (typ) | 0.69 V at IF = 15 A, Tj = 125 °C - Low conduction loss enables >94% efficiency in 12 V/30 A secondary-side rectification. |
| IR (max) | 8.0 mA at VR = 150 V, Tj = 125 °C - Low leakage preserves efficiency at elevated ambient temperatures in enclosed enclosures. |
| Rth(j-c) total | 0.85 °C/W - Thermal resistance from junction to case (both diodes); determines ΔTj rise under 30 A load with known heatsink interface. |
| Tj(max) | +175 °C - Maximum operating junction temperature; allows derated operation up to 155 °C ambient with proper thermal design. |
| PARM | 750 W at tp = 10 µs, Tj = 125 °C - Avalanche energy rating supports robustness against inductive switching transients in flyback or LLC resonant converters. |
Pinout & Package
STPS30150CG is housed in a surface-mount D²PAK (TO-263) package with three terminals: two anodes (A1, A2) and one shared cathode (K). The package features a copper-exposed tab for direct thermal mounting to PCB copper pour or heatsink, and complies with ECOPACK®2 environmental standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input connection for first half-cycle rectification; tied to transformer secondary winding end 1. |
| A2 | Anode of Diode 2 | Input connection for second half-cycle rectification; tied to transformer secondary winding end 2. |
| K | Common Cathode | Output node for full-wave rectified DC; connects to output capacitor and load return path. |
Key Features
| Feature | Design Value |
|---|---|

| Avalanche-rated power | 750 W (10 µs pulse) - Provides built-in transient overvoltage protection during MOSFET turn-off spikes in hard-switched topologies. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant epoxy; meets UL 94 V0 flammability rating for safety-critical power systems. |
| Thermal performance | Rth(j-c) = 0.85 °C/W (total) - Enables compact thermal design with ≥100 cm² 35 µm Cu on FR4 for ≤50 °C ΔTj rise at full load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-center-tap Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH015-M3 | Same VRRM (150 V), higher IF(AV) = 30 A/device, but Rth(j-c) = 1.2 °C/W (D²PAK); VF = 0.75 V @ 15 A, 125 °C. | Better current rating but higher conduction loss and worse thermal resistance; requires larger PCB copper area. | Select when peak current surges exceed 30 A and thermal margin permits higher ΔTj. |
| ON Semiconductor MBR30150CT | VRRM = 150 V, IF(AV) = 15 A/diode, but TO-220AB package (Rth(j-c) = 1.6 °C/W per diode); no avalanche rating specified. | Through-hole mounting only; lacks transient robustness for high-dV/dt SMPS; lower thermal performance. | Select only for legacy through-hole designs where board rework is prohibitive and surge immunity is not required. |
Compared with VS-30CPH015-M3 and MBR30150CT, STPS30150CG uniquely combines low VF (0.69 V), low Rth(j-c) (0.85 °C/W total), and certified avalanche capability - making it optimal for thermally constrained, high-reliability SMPS where both efficiency and transient robustness are mandatory.

FAQ
Is STPS30150CG suitable for synchronous rectification in LLC resonant converters?
Yes. Its 150 V VRRM, 0.69 V VF at 125 °C, and fast intrinsic recovery make it suitable for secondary-side synchronous rectification in LLC converters up to 500 kHz. The dual-center-tap configuration simplifies gate drive routing, and its 175 °C Tj(max) supports operation under high RMS current stress typical in resonant topologies.
What is the maximum recommended PCB copper area for thermal management of STPS30150CG in D²PAK?
For continuous 30 A operation at 60 °C ambient, ST recommends ≥100 cm² of 35 µm copper on the component side, directly connected to the exposed tab. Figure 9 in the datasheet shows Rth(j-a) drops from ~25 °C/W (no copper) to ~12 °C/W with 100 cm², enabling safe junction temperatures below 150 °C.
Does STPS30150CG require external snubbers in high-dV/dt applications?
No external snubber is required for typical SMPS operation due to its specified avalanche capability (750 W, 10 µs). However, for dV/dt exceeding 500 V/µs or repetitive unclamped inductive switching, a small RC snubber (e.g., 100 Ω + 100 pF) across each anode-to-cathode improves long-term reliability.
Can STPS30150CG be paralleled with another unit for higher current capacity?
Paralleling is not recommended. The device lacks matched VF characteristics between units, leading to current imbalance. For >30 A applications, use a single higher-rated part (e.g., STPS40150CW) or redesign with interleaved phases - both ensure balanced thermal and electrical loading without derating penalties.
