Product details
Overview
STPS10150CT from STMicroelectronics is a dual-center-tab high-voltage Schottky rectifier in TO-220AB package, rated for 150 V repetitive peak reverse voltage, 5 A average forward current per diode (10 A total), and 175 °C maximum junction temperature. It delivers low forward voltage drop (0.69 V typ. at 125 °C, 5 A) and low leakage current (2.0 µA max. at 25 °C), optimized for high-frequency switched-mode power supplies in industrial AC/DC adapters and server PSUs.
For engineers reviewing the STPS10150CT datasheet, STPS10150CT pinout, STPS10150CT application, or STPS10150CT equivalent, key selection criteria include its dual-diode thermal coupling behavior, insulated case rating (2000 VRMS), avalanche energy capability (220 W at 10 µs), and package-specific thermal resistance (4 °C/W j-c per diode in TO-220AB).
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 150 V/5 A diodes sharing a thermally coupled case. Its low VF–IR trade-off enables high-efficiency operation in continuous conduction mode (CCM) PFC stages and secondary-side synchronous rectification where junction temperature stability up to 175 °C is critical.
The device supports avalanche-rated operation (PARM = 220 W, tp = 10 µs, Tj = 125 °C) and features an insulated TO-220AB package with 2000 VRMS isolation-enabling direct mounting to grounded heatsinks without additional insulation hardware in isolated DC/DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Withstands 150 V repetitive reverse voltage without breakdown; suitable for 110–120 VAC input rectification with margin. |
| IF(AV) per diode | 5 A - Sustains 5 A average forward current per diode at Tc = 155 °C; total device rating is 10 A with shared thermal path. |
| VF (typ) | 0.69 V at 125 °C, 5 A - Enables <1.5 W conduction loss per diode in high-efficiency SMPS designs. |
| IR (max) | 2.0 µA at 25 °C, VR = VRRM - Minimizes standby power loss in no-load or light-load conditions. |
| Rth(j-c) per diode | 4 °C/W - Allows precise thermal modeling when mounted on heatsink; total device Rth(j-c) = 2.4 °C/W (parallel path). |
| Tj(max) | 175 °C - Supports operation in high-ambient environments (e.g., enclosed server PSUs) without derating below full current. |
| PARM | 220 W at tp = 10 µs, Tj = 125 °C - Provides robust transient surge handling during output short-circuit events. |
Pinout & Package
STPS10150CT uses the TO-220AB package with three terminals: two anodes (A1, A2) and one common cathode (K). The metal tab is electrically connected to the cathode and provides mechanical mounting and thermal conduction. Insulation rating is 2000 VRMS between tab and leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first Schottky diode; connects to AC input or switching node in dual-phase rectifier. |
| A2 | Anode 2 | Input terminal for second Schottky diode; enables interleaved or redundant rectification paths. |
| K (Tab) | Common Cathode | Shared output node; electrically tied to metal tab-requires insulating washer if mounted to grounded heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | Rated for continuous operation up to 175 °C junction temperature-reduces need for oversized heatsinks in compact power modules. |
| Low VF–IR trade-off | 0.69 V VF (typ) at 125 °C + 2.0 µA IR (max) at 25 °C-balances efficiency and leakage in high-frequency, high-temperature operation. |
| Avalanche energy rating | 220 W repetitive avalanche power (tp = 10 µs)-protects against inductive switching transients in flyback or LLC resonant converters. |
| Insulated TO-220AB package | 2000 VRMS isolation between tab and leads-eliminates need for mica washers in isolated topologies like offline flyback PSUs. |
Applications
| Server AC/DC Power Supply | Industrial Motor Drive Front-End |
|---|---|
Use Scenario: High-density 1U server PSU with active PFC and LLC resonant DC/DC stage. IC Role / Device Role / Timing Role: Dual-diode common-cathode Schottky rectifier used in bridgeless PFC input stage and secondary-side synchronous rectification.

IC Role / Device Role / Timing Role: Dual-anode configuration enables parallel OR-ing paths with shared cathode output to load. Use Value: Low IR (<2 µA at 25 °C) prevents reverse-current backfeed during module switchover, preserving system uptime. | Use Scenario: X-ray generator high-voltage DC supply requiring low EMI and zero recovery noise. IC Role / Device Role / Timing Role: Output rectifier in resonant high-voltage transformer secondary winding. Use Value: Zero reverse recovery charge eliminates switching spikes that interfere with sensitive analog signal chains in imaging detectors. |
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 | Same VRRM (150 V), IF(AV) = 5 A per diode, but TO-220AC package (non-insulated tab); Rth(j-c) = 5.5 °C/W per diode. | Lacks 2000 VRMS insulation-requires external isolation for grounded heatsink mounting. | Select when cost sensitivity outweighs insulation requirement and thermal margin allows higher Rth. |
| ON Semiconductor MBR10150CT | Identical ratings (150 V, 5 A × 2), TO-220AB package, but no specified avalanche rating; IR = 3.0 µA max (vs. 2.0 µA). | No PARM specification-unsuitable for designs requiring validated avalanche surge immunity. | Prefer for non-safety-critical consumer PSUs where avalanche validation is not mandated by standards. |
Compared with VS-10BQ015 and MBR10150CT, STPS10150CT uniquely combines certified 2000 VRMS insulation, 220 W avalanche rating, and tighter IR spec-making it the only choice for UL/IEC-compliant industrial and medical power systems requiring both isolation and transient robustness.

FAQ
What is the thermal coupling behavior between the two diodes in STPS10150CT?
The two diodes share a common thermal path through the TO-220AB case. When operated simultaneously, junction temperature rise of Diode 1 depends on both its own power dissipation and Diode 2's dissipation via Rth(c) = 0.7 °C/W coupling. This requires joint thermal modeling using ΔTj(diode1) = P1 × 4 + P2 × 0.7 (°C/W), per datasheet Equation in Section 2.
Can STPS10150CT be used in place of a single 10 A Schottky diode?
No-it is a dual 5 A device with shared cathode, not a single 10 A diode. Its total IF(AV) rating of 10 A assumes both diodes conduct equally and share thermal load. Using only one anode de-rates the device to 5 A IF(AV) at Tc = 155 °C, and violates the thermal design basis stated in Table 2.
Is the metal tab electrically isolated from the leads in STPS10150CT?
Yes-the TO-220AB package is insulated: the metal tab (cathode) is isolated from all leads with 2000 VRMS withstand voltage (sine wave, 1 min). This allows direct mounting to grounded heatsinks without additional insulation, unlike standard TO-220AC variants.
Does STPS10150CT meet RoHS and REACH requirements?
Yes-STPS10150CT is ECOPACK®2 compliant, meeting EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free termination and halogen-free molding compound are confirmed in ST's official compliance documentation (DocID7754 Rev 7, Section 2).
