Product details
Overview
STPS30150CFP from STMicroelectronics is a dual-center-tap high-voltage Schottky rectifier in insulated TO-220FPAB package, rated for 150 V reverse voltage, 15 A average forward current per diode (30 A per device), and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.69 V typ. at 125 °C, 15 A) and low leakage current (8.0 mA max at 125 °C, VRRM), optimized for high-frequency switch-mode power supplies in industrial AC/DC adapters and server PSUs.
For engineers reviewing the STPS30150CFP datasheet, STPS30150CFP pinout, STPS30150CFP application, or STPS30150CFP equivalent, key selection criteria include thermal resistance (Rth(j-c) = 4 °C/W per diode), insulating capability (2000 VRMS), avalanche rating (750 W, 10 µs), and dual-diode center-tap configuration for synchronous rectification and full-wave bridge replacement.
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode paths sharing a common cathode terminal (center-tap topology), enabling full-wave rectification without external interconnection. Its silicon Schottky barrier design eliminates minority-carrier storage delay, supporting switching frequencies beyond 500 kHz.
The TO-220FPAB package provides reinforced insulation (2000 VRMS) between mounting tab and internal die, allowing direct heatsink attachment without isolation hardware. Thermal coupling between diodes is characterized by Rth(c) = 2.6 °C/W, enabling accurate junction temperature estimation under simultaneous conduction.
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 designs. |
| IF(AV) | 15 A per diode / 30 A per device - Continuous DC output current capability at TC = 120 °C (per diode) or 90 °C (device); determines heatsink sizing. |
| VF (typ) | 0.69 V at Tj = 125 °C, IF = 15 A - Low conduction loss enables >94% efficiency in 12 V/24 V secondary-side rectification. |
| IR (max) | 8.0 mA at Tj = 125 °C, VR = VRRM - Low leakage preserves light-load efficiency and reduces standby power in energy-compliant designs. |
| Rth(j-c) | 4 °C/W per diode - Junction-to-case thermal resistance in TO-220FPAB; used with heatsink Rth(c-a) to calculate total thermal path. |
| PARM | 750 W at tp = 10 µs, Tj = 125 °C - Avalanche energy rating supports robustness against transient overvoltage events in unregulated flyback outputs. |
Pinout & Package
STPS30150CFP uses the insulated TO-220FPAB package (2000 VRMS isolation), with three terminals: two anodes (A1, A2) and one common cathode (K). The metal tab is electrically isolated from the die and serves solely as a thermal interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first half-cycle in center-tapped transformer secondary; connects to transformer winding end 1. |
| A2 | Anode 2 | Input terminal for second half-cycle; connects to transformer winding end 2 - opposite polarity to A1 relative to K. |
| K | Common Cathode | Output node for full-wave rectified DC; carries combined current of both diodes; must be routed with low-inductance PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Insulated TO-220FPAB package | 2000 VRMS isolation enables direct mounting to grounded heatsinks without mica washers or silicone pads - reducing thermal resistance and assembly cost. |
| High Tj operation | 175 °C maximum junction temperature allows sustained operation in compact, high-power-density enclosures with limited airflow. |
| Avalanche-rated structure | 750 W peak avalanche power (10 µs) ensures reliable clamping during output short-circuit or transformer reset overshoot in flyback converters. |
| Low VF / IR trade-off | 0.69 V forward drop at 125 °C with only 8.0 mA leakage balances conduction loss and standby dissipation better than standard Schottky alternatives. |
Applications
| Server Power Supply Rectification | Industrial AC/DC Adapter Output Stage |
|---|---|
|
Use Scenario: Secondary-side rectification in 80 PLUS Titanium-certified 1 kW server PSUs using active clamp flyback or LLC resonant topologies. IC Role / Device Role / Timing Role: Dual-center-tap Schottky rectifier replacing discrete diode pairs; conducts during positive half-cycles of transformer secondary voltage referenced to common cathode. Use Value: 0.69 V typical VF at 125 °C reduces conduction loss by ~18% vs. legacy 0.85 V Schottkys, directly improving full-load efficiency and thermal margin. |
Use Scenario: Output rectification in 24 V/30 A industrial DIN-rail power supplies operating continuously at 60 °C ambient. IC Role / Device Role / Timing Role: Center-tapped full-wave rectifier converting transformer secondary AC into regulated DC; handles 30 A continuous output with shared thermal path. Use Value: 4 °C/W Rth(j-c) per diode and 2.6 °C/W coupling enable precise thermal modeling for derating - critical for 24/7 reliability certification. |
| Telecom Brick DC/DC Converter | LED Driver Secondary Side |
|
Use Scenario: Isolated 48 V input, 12 V/40 A output telecom brick with tight size constraints and forced-air cooling. IC Role / Device Role / Timing Role: High-frequency synchronous rectifier alternative; operates at 300–500 kHz with negligible reverse recovery charge. Use Value: Zero Qrr eliminates switching loss associated with BJT/MOSFET synchronous gate drive complexity - simplifying control loop design. |
Use Scenario: Constant-current LED driver for high-bay lighting, requiring low EMI and high efficiency at partial load. IC Role / Device Role / Timing Role: Full-wave rectifier in quasi-resonant flyback output stage; supplies DC bus to constant-current buck regulator. Use Value: 8.0 mA max IR at 125 °C minimizes no-load power draw, helping meet IEC 62301 standby < 0.5 W requirements. |
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-30CPH07-M3 | 70 V VRRM, 30 A total IF(AV), TO-247 package, no insulation (Rth(j-c) = 0.8 °C/W) | Limited to ≤48 V systems; requires isolated mounting hardware for grounded heatsinks | Select when higher current density and lower thermal resistance are prioritized over voltage rating and insulation. |
| ON Semiconductor MBR30H150CT | 150 V VRRM, 30 A total IF(AV), TO-220AB (non-insulated), Rth(j-c) = 1.6 °C/W per diode | Requires insulating kit for heatsink mounting; higher forward drop (0.82 V typ. at 125 °C) | Choose for cost-sensitive industrial designs where isolation can be added externally and 0.13 V higher VF is acceptable. |
Compared with VS-30CPH07-M3 and MBR30H150CT, STPS30150CFP uniquely combines 150 V rating, 2000 VRMS insulation, and sub-0.7 V forward drop - making it the only option qualified for insulated, high-efficiency, high-voltage secondary-side rectification without added BOM components.

FAQ
What is the mounting torque specification for the STPS30150CFP TO-220FPAB package?
The recommended mounting torque for STPS30150CFP's TO-220FPAB package is 0.55 N·m, with a maximum allowable torque of 0.7 N·m. Exceeding this limit risks cracking the molded epoxy body or compromising internal wire bonds. Torque must be applied evenly using a calibrated torque screwdriver on the single mounting hole.
Can STPS30150CFP replace a standard TO-220AB dual Schottky in an existing design?
Yes, but only if the original design uses a non-insulated TO-220AB part and the heatsink is electrically isolated. STPS30150CFP's TO-220FPAB has identical footprint and pinout but adds 2000 VRMS insulation - eliminating need for mica/silicone isolators. Thermal resistance is higher (4 °C/W vs. 1.6 °C/W), so heatsink performance must be re-verified.
How is the 30 A device rating achieved with only 15 A per diode?
The 30 A rating applies when both diodes conduct alternately in a center-tapped full-wave configuration - each diode carries the full load current for half the cycle, resulting in equal RMS and average current distribution. This is validated at TC = 90 °C case temperature, not junction temperature, per Table 2 in the datasheet.
Does STPS30150CFP support paralleling for higher current?
No - STPS30150CFP is not characterized for parallel operation. Its forward voltage temperature coefficient is not tightly matched between diodes, risking current imbalance. For >30 A applications, ST recommends using multiple STPS30150CFP units in separate transformer secondary windings or selecting higher-rated alternatives like STPS40L150C in D²PAK.
