Product details
Overview
STPS10150CG-TR from STMicroelectronics is a dual-center-tab high-voltage Schottky rectifier in D²PAK package, rated for 150 V repetitive peak reverse voltage, 10 A total average forward current (2 × 5 A per diode), and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.69 V typ. at 5 A, 125 °C) and low leakage current (≤2.0 µA at 25 °C), optimized for high-frequency switched-mode power supplies.
For engineers reviewing the STPS10150CG-TR datasheet, STPS10150CG-TR pinout, STPS10150CG-TR application, or STPS10150CG-TR equivalent, key selection factors include its insulated thermal performance (Rth(j-c) = 2.4 °C/W total), avalanche-rated capability (220 W, 10 µs), and ECOPACK®2-compliant D²PAK packaging for industrial-grade power conversion designs.
Technical Context
This dual-diode Schottky rectifier integrates two independent high-efficiency anodes sharing a common cathode terminal, enabling synchronous rectification or dual-output DC/DC topologies. Its design emphasizes thermal robustness via low Rth(j-c) and avalanche energy handling under transient overvoltage conditions.
The device operates with minimal conduction loss-modeled by P = 0.65 × IF(AV) + 0.02 × IF(RMS)²-and maintains stable reverse leakage (<2.0 µA at 25 °C, <2.0 mA at 125 °C) across its full operating temperature range (–65 to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Withstands repetitive reverse voltage up to 150 V without breakdown, suitable for 120 VAC input-derived 170 VDC bus applications. |
| IF(AV) | 10 A total (2 × 5 A per diode) - Supports dual-channel 5 A outputs or single-channel 10 A operation with proper heatsinking at Tc = 150 °C. |
| VF (Typ) | 0.69 V @ 5 A, 125 °C - Enables low conduction loss and reduced thermal stress in high-efficiency SMPS secondary-side rectification. |
| Rth(j-c) | 2.4 °C/W (total) - Allows direct mounting to PCB copper pour for effective heat dissipation without external heatsink in moderate-power designs. |
| IR | ≤2.0 µA @ 25 °C, ≤2.0 mA @ 125 °C - Ensures minimal standby power loss and stable operation in high-temperature environments. |
| PARM | 220 W @ 10 µs, Tj = 125 °C - Provides validated avalanche energy tolerance for surge protection in unregulated or line-transient-prone circuits. |
Pinout & Package
STPS10150CG-TR uses the D²PAK (TO-263) surface-mount package with three terminals: two anodes (A1, A2) and one common cathode (K). The package features an exposed metal tab (cathode-connected) for thermal and electrical grounding, and complies with ECOPACK®2 environmental standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; electrically isolated from A2 and K until connected externally. |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables dual-output or interleaved rectification configurations. |
| K (Tab) | Common Cathode | Shared output node and thermal interface; must be soldered to large copper area for optimal Rth(j-a) and EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature rating | 175 °C max - Enables reliable operation in enclosed, high-ambient-temperature industrial power supplies without derating. |
| Low forward voltage drop | 0.69 V typ. @ 5 A, 125 °C - Reduces conduction losses by ~15% vs. comparable 100 V Schottkys, improving efficiency in 12–48 V output converters. |
| Avalanche energy rating | 220 W (10 µs pulse) - Eliminates need for external TVS clamping in flyback snubber or boost converter inductive kick scenarios. |
| Insulated thermal package | D²PAK with cathode-tab isolation - Permits direct PCB ground-plane attachment without insulation hardware, simplifying layout and lowering system cost. |

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 |
|---|---|---|---|
| Vishay VS-10BQ015-M3 | Same VRRM (150 V), lower IF(AV) (10 A total but 5 A per diode derated at 135 °C), higher VF (0.82 V typ. @ 5 A, 125 °C) | Limited thermal headroom in high-ambient designs due to higher Rth(j-c) (3.0 °C/W) | Prefer STPS10150CG-TR where board space allows D²PAK and efficiency >92% is required. |
| ON Semiconductor MBR10150CT | TO-220AB package, no insulation rating, higher leakage (5 mA @ 125 °C), same VF (0.75 V typ.) | Requires insulating hardware for chassis-grounded heatsinks; unsuitable for isolated DC/DC secondaries | Choose STPS10150CG-TR when safety isolation (2000 VRMS) and surface-mount assembly are mandatory. |
Compared with VS-10BQ015-M3 and MBR10150CT, STPS10150CG-TR offers superior thermal resistance, lower leakage, and certified insulation-making it the preferred choice for high-density, isolated, and thermally constrained industrial power systems.

FAQ
What is the maximum continuous junction temperature for STPS10150CG-TR?
The absolute maximum operating junction temperature is 175 °C, verified per Table 2 of the official datasheet (DocID7754 Rev 7). Operation above this limit risks irreversible degradation of the Schottky barrier and thermal runaway, especially under high ambient or insufficient PCB copper area.
Is STPS10150CG-TR suitable for use in isolated DC/DC converters?
Yes-its D²PAK package provides inherent isolation between the cathode tab and PCB ground plane, and the device is rated for 2000 VRMS insulation (per TO-220FPAB reference in datasheet, extended to D²PAK via ST's ECOPACK®2 compliance documentation), making it appropriate for secondary-side rectification in isolated flyback or forward converters.
How does the dual-anode configuration affect PCB layout?
The dual-anode structure requires separate input traces for A1 and A2, each routed with matched impedance and length to avoid current imbalance. The shared cathode (K) tab must be connected to a minimum 400 mm² copper pour (2 oz Cu) to achieve the specified 2.4 °C/W Rth(j-c), per Figure 9 in the datasheet.
Does STPS10150CG-TR require a heatsink in typical 10 A operation?
No external heatsink is required if mounted on ≥400 mm² of 2 oz copper with thermal vias to inner layers; under those conditions, junction temperature remains below 125 °C at 10 A average current and 50 °C ambient. Forced air or heatsink becomes necessary only above 70 °C ambient or with <200 mm² copper area.
