Product details
Overview
STPS30150CW from STMicroelectronics is a dual-center-tap high-voltage Schottky rectifier in TO-247 package, rated for 150 V repetitive reverse voltage and 15 A average forward current per diode (30 A total device), with typical forward voltage drop of 0.69 V at 125 °C and 15 A, low leakage (8.0 mA at 125 °C), and avalanche-rated power of 750 W - designed for primary-side rectification in high-frequency switch-mode power supplies.
For engineers reviewing the STPS30150CW datasheet, STPS30150CW pinout, STPS30150CW application, or STPS30150CW equivalent, key selection criteria include thermal resistance (Rth(j-c) = 0.8 °C/W), insulated mounting capability, avalanche ruggedness, and dual-diode center-tap configuration for synchronous or center-tapped transformer topologies.
Technical Context
This dual Schottky rectifier integrates two anti-parallel-connected anodes sharing a common cathode terminal, enabling center-tapped transformer secondary rectification without external wiring. Its low Qrr and absence of minority-carrier storage minimize switching losses in 100–500 kHz SMPS designs.
The TO-247 package provides low junction-to-case thermal resistance (0.8 °C/W) and mechanical robustness for high-power conduction, while the specified avalanche capability (750 W, 10 µs pulse) supports transient energy absorption during inductive turn-off events in flyback or forward converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum reverse blocking voltage per diode; enables use in 12 V–48 V output systems with ≥2× safety margin against reflected spikes. |
| IF(AV) | 15 A per diode / 30 A total - Continuous DC current handling at TC = 150 °C; supports >300 W output in well-heatsinked 200–300 kHz LLC or forward converters. |
| VF (typ) | 0.69 V @ 15 A, 125 °C - Low conduction loss reduces power dissipation to ~10.4 W per diode at full load, easing thermal design. |
| Rth(j-c) | 0.8 °C/W - Junction-to-case thermal resistance for TO-247; allows ≤120 °C junction rise with 100 W dissipation under forced convection. |
| IR (max) | 8.0 mA @ 125 °C - Reverse leakage remains low at elevated temperature, preventing excessive standby loss in offline adapters. |
| PARM | 750 W @ 10 µs - Avalanche energy rating ensures survivability during MOSFET turn-off overshoot in non-clamped topologies. |
Pinout & Package
STPS30150CW uses the TO-247 package: isolated metal tab (cathode common), three leads - two anodes (A1, A2) and one shared cathode (K). Mounting hole accepts M3 screw (torque: 0.55 N·m recommended, 1.0 N·m max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Connects to one end of center-tapped transformer secondary; conducts during first half-cycle. |
| A2 | Anode 2 | Connects to opposite end of center-tapped secondary; conducts during second half-cycle. |
| K | Common Cathode | Output node for full-wave rectified DC; electrically tied to heatsink via isolated tab (2000 VRMS isolation not applicable - TO-247 is non-insulated). |
Key Features
| Feature | Design Value |
|---|---|
| Dual center-tap Schottky topology | Eliminates need for external diode pairing and interconnects; reduces layout parasitics and improves current sharing accuracy. |
| 175 °C maximum junction temperature | Enables operation in high-ambient environments (e.g., enclosed industrial PSUs) without derating below 150 °C case temperature. |
| Avalanche-rated (750 W, 10 µs) | Withstands unclamped inductive switching transients without failure - critical for flyback and resonant converter reliability. |
| Low Rth(j-c) = 0.8 °C/W (TO-247) | Supports >200 W continuous conduction with standard extruded aluminum heatsinks and thermal interface material. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements for industrial and telecom equipment compliance. |

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 | Same VRRM (150 V), higher IF(AV) (18 A/diode), but Rth(j-c) = 1.0 °C/W (TO-247); VF = 0.72 V @ 125 °C. | Higher current headroom but 25% higher thermal resistance limits peak power density in space-constrained modules. | Select when >18 A per diode is required and thermal margin permits higher junction rise. |
| ON Semiconductor MBR30150CT | Identical VRRM/IF(AV), but TO-220AB package (Rth(j-c) = 1.6 °C/W); VF = 0.82 V @ 125 °C; no avalanche rating. | Limited to <150 W continuous operation; unsuitable for unclamped topologies requiring avalanche ruggedness. | Select only for cost-sensitive, lower-power (<120 W), non-avalanche-critical applications with ample heatsinking. |
Compared with VS-30CPH015 and MBR30150CT, STPS30150CW uniquely balances low thermal resistance (0.8 °C/W), verified avalanche capability (750 W), and tight VF distribution (0.69 V typ.), making it optimal for high-density, high-reliability 200–400 W SMPS where thermal and transient robustness are co-critical.

FAQ
Is STPS30150CW suitable for synchronous rectification?
No - STPS30150CW is a passive Schottky rectifier, not a synchronous rectifier IC. It replaces MOSFET-based synchronous rectifiers in center-tapped topologies where gate drive complexity or cost must be minimized. Its zero reverse recovery enables clean switching but lacks active control circuitry.
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature for continuous IF(AV) = 30 A operation is 150 °C, as specified in Table 2. Exceeding this requires proportional current derating per Figure 2; at 120 °C case, maximum IF(AV) drops to 22 A per device.
Does the TO-247 package provide electrical isolation between tab and leads?
No - unlike TO-220FPAB, the TO-247 package used in STPS30150CW has a conductive metal tab electrically connected to the cathode (K) terminal. Isolation must be achieved externally using insulating washers or pads if mounting to a grounded heatsink.
Can STPS30150CW replace STPS30150CT in existing designs?
Yes, with thermal and mechanical validation: both share identical electrical specs, but STPS30150CW (TO-247) offers 47% lower Rth(j-c) than STPS30150CT (TO-220AB). PCB footprint, mounting torque (1.0 N·m max), and heatsink interface must be requalified for the larger TO-247 outline and higher power density.
