Product details
Overview
STPS20150CG-TR from STMicroelectronics is a dual-center-tap Schottky rectifier in D²PAK (TO-263) package, rated for 150 V repetitive peak reverse voltage and 2 × 10 A average forward current per diode at TC = 155 °C, with typical forward voltage drop of 0.69 V at 10 A and 25 °C - optimized for high-frequency switch-mode power supplies in server PSUs and telecom rectifiers.
For engineers reviewing the STPS20150CG-TR datasheet, STPS20150CG-TR pinout, STPS20150CG-TR application, or STPS20150CG-TR equivalent, key selection criteria include thermal resistance (Rth(j-c) = 2.2 °C/W per diode), avalanche capability (480 W, tp = 10 µs), insulated package option (TO-220FPAB variant), and ECOPACK®2 compliance for D²PAK delivery format.
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 full-wave bridge or center-tapped transformer topologies. Its low VF and high Tj(max) = 175 °C support high-efficiency, high-power-density DC/DC conversion.
Designed for operation without forced cooling, it leverages low Rth(j-c) = 2.2 °C/W (per diode, D²PAK) and specified surge current IFSM = 180 A (10 ms sine), while maintaining low IR = 5.0 µA at 25 °C and VR = 150 V - critical for standby loss minimization in energy-efficient power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - supports input stages up to 100 V DC bus with safety margin for transient spikes in telecom and industrial SMPS. |
| IF(AV) per diode | 10 A at TC = 155 °C - enables 20 A total device output in center-tap configuration with standard heatsinking. |
| VF(typ) | 0.69 V at IF = 10 A, Tj = 25 °C - reduces conduction loss to ~6.9 W per diode, improving efficiency over silicon diodes by >30%. |
| Tj(max) | 175 °C - allows sustained operation in compact enclosures with ambient temperatures up to 125 °C when derated. |
| Rth(j-c) per diode | 2.2 °C/W - permits 10 A continuous current with ≤22 K temperature rise from junction to case, simplifying thermal design. |
| IFSM | 180 A (10 ms sine) - withstands inrush currents during cold-start in high-capacity power supplies without failure. |
| IR(max) | 5.0 mA at Tj = 125 °C, VR = 150 V - ensures minimal leakage-induced standby power loss in always-on systems. |
Pinout & Package
D²PAK (TO-263) surface-mount package with exposed metal tab for thermal conduction; 3-pin configuration: Pin 1 = Anode 1, Pin 2 = Cathode (common center tap), Pin 3 = Anode 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Connects to transformer secondary winding leg 1 or switching node in half-bridge rectification path. |
| Pin 2 | Common Cathode (Center Tap) | Output node for full-wave rectified DC; requires low-inductance PCB copper pour for thermal and electrical performance. |
| Pin 3 | Anode of Diode 2 | Connects to transformer secondary winding leg 2 or complementary switching node in symmetrical topology. |
Key Features
| Feature | Design Value |
|---|---|
| Avalanche-rated power handling | 480 W (tp = 10 µs, Tj = 125 °C) - enables robustness against voltage transients without external clamping. |
| High-temperature junction rating | 175 °C maximum operating temperature - supports reliability in sealed, fanless, or high-ambient environments. |
| Low forward voltage trade-off | 0.69 V typ. @ 10 A / 25 °C with <5 µA IR @ 25 °C - balances conduction loss and leakage for high-efficiency SMPS. |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant D²PAK packaging - meets environmental requirements for industrial and telecom equipment. |
| Insulated package variant available | TO-220FPAB version offers 2000 VRMS isolation - eliminates need for insulating washers in chassis-grounded designs. |
Applications
| Server Power Supply Rectification | Telecom AC/DC Front-End |
|---|---|

IC Role / Device Role / Timing Role: Output rectifier in high-frequency flyback transformer secondary with center-tapped winding. Use Value: Supports continuous 10 A output with <0.75 V VF at 125 °C, ensuring stable auxiliary rail under full-load thermal stress. | Use Scenario: Isolated gate driver supply in solar string inverters, derived from DC link via flyback or forward converter. IC Role / Device Role / Timing Role: Secondary-side Schottky rectifier delivering isolated 15 V/200 mA bias for IGBT/SiC gate drivers. Use Value: Low IR (<5 µA at 25 °C) prevents standby power drain; 175 °C rating sustains operation during extended outdoor thermal cycling. |
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-20CPH15 | D²PAK package, same 150 V VRRM and 2 × 10 A rating, but VF = 0.82 V typ. @ 10 A - higher conduction loss. | Lacks specified avalanche rating (480 W); not qualified for transient-heavy industrial environments. | Prefer for cost-sensitive, lower-thermal-budget designs where transient immunity is secondary. |
| ON Semiconductor MBR20150CT | TO-220AB package, identical electrical specs, but Rth(j-c) = 2.5 °C/W (vs. 2.2 °C/W) and no ECOPACK®2 certification. | Requires mechanical insulation kit for chassis mounting; unsuitable for halogen-free compliance programs. | Select when through-hole assembly is mandated or when legacy TO-220 footprint compatibility is required. |
Compared with VS-20CPH15 and MBR20150CT, STPS20150CG-TR delivers superior thermal performance (0.3 °C/W lower Rth), guaranteed avalanche ruggedness, and full environmental compliance - making it optimal for next-generation high-reliability, high-efficiency power systems.

FAQ
What is the thermal resistance from junction to case for STPS20150CG-TR?
The junction-to-case thermal resistance (Rth(j-c)) is 2.2 °C/W per diode in the D²PAK package, measured under standard test conditions with the tab mounted to a large copper area. This value assumes conduction cooling only and does not include PCB or heatsink interface resistance.
Does STPS20150CG-TR support center-tapped transformer configurations?
Yes - it is explicitly designed as a dual-center-tap Schottky rectifier with two anodes (Pins 1 and 3) and one shared cathode (Pin 2), enabling direct integration into center-tapped transformer secondary windings for full-wave rectification without external interconnects.
Is STPS20150CG-TR compliant with RoHS and halogen-free standards?
Yes - it is certified ECOPACK®2 compliant, meeting RoHS Directive 2011/65/EU and halogen-free requirements (IEC 61249-2-21), with bromine and chlorine content below 900 ppm each and total halogens <1500 ppm.
What is the maximum surge current rating for STPS20150CG-TR?
The non-repetitive peak forward surge current (IFSM) is 180 A for a 10 ms half-sine wave pulse, verified per IEC 61000-4-5 and JEDEC JESD22-A112 standards, and applies to each diode independently under specified thermal conditions.
