Product details
Overview
STPS60150CT from STMicroelectronics is a dual-center-tab Schottky rectifier in TO-220AB package, rated for 2 × 30 A average forward current per diode and 150 V repetitive peak reverse voltage, with typical forward voltage of 0.72 V at 125 °C and 30 A - optimized for high-frequency SMPS and telecom power supplies.
For engineers reviewing the STPS60150CT datasheet, STPS60150CT pinout, STPS60150CT application, or STPS60150CT equivalent, key selection criteria include junction-to-case thermal resistance (1.0 °C/W per diode), avalanche power rating (1245 W), low leakage (<10 mA at 125 °C), dual-diode thermal coupling behavior, and ECOPACK®2 compliance for industrial-grade reliability.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 150 V/30 A diodes sharing a thermally coupled center tab, enabling simultaneous conduction with predictable thermal interaction modeled by ΔTj(diode1) = P₁×Rth(j-c) + P₂×Rth(c). Its low VF and fast recovery support high-efficiency DC/DC conversion above 100 kHz.
The device operates up to 175 °C junction temperature, features 0.4 °C/W inter-diode coupling resistance, and delivers 270 A non-repetitive surge capability under 10 ms sinusoidal stress - critical for transient-tolerant telecom front-end rectification and server PSU hold-up stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - supports input rectification in 48 V telecom systems with 20 % safety margin against line transients |
| IF(AV) per diode | 30 A at TC = 145 °C - enables compact heatsink design for dual-rail 60 A output in space-constrained PSUs |
| VF(typ.) | 0.72 V at 30 A, 125 °C - reduces conduction loss to ~21.6 W per diode vs. silicon diodes (>1.1 V) |
| Rth(j-c) per diode | 1.0 °C/W - allows direct mounting to heatsink without thermal interface degradation beyond 150 W dissipation |
| IR(max) | 10 mA at 125 °C, VR = 150 V - ensures minimal standby loss in always-on telecom power modules |
| PARM | 1245 W at tp = 10 µs - withstands lightning-induced surges without avalanche failure in AC-DC front ends |
Pinout & Package
TO-220AB package with center-tab cathode configuration: pins are anode1 (lead 1), anode2 (lead 2), and common cathode (center tab, electrically connected to metal tab). Mounting torque: 0.55 N·m (recommended), max 0.70 N·m. Epoxy meets UL 94 V0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 | Anode of Diode 1 | Input terminal for first rectifier path; isolated from other leads except via PCB trace |
| Lead 2 | Anode of Diode 2 | Independent input for second rectifier path; enables dual-output or phase-split configurations |
| Center Tab | Common Cathode | Electrically and thermally tied to both diodes' cathodes; must be mounted to heatsink for thermal and electrical reference |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | Tj(max) = 175 °C - extends lifetime in sealed telecom enclosures with limited airflow |
| Low thermal resistance | Rth(j-c) = 1.0 °C/W per diode - enables >90 % of rated current with standard TO-220 heatsinks |
| Avalanche-rated operation | 1245 W peak avalanche power - eliminates need for external clamping in inductive load switching |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant materials - satisfies EU environmental mandates for telecom infrastructure |
Applications
| Telecom AC-DC Front End | Server PSU Secondary Side |
|---|---|
Use Scenario: Rectifying 48 V DC input in telecom shelf power modules with high ambient temperature and strict efficiency targets. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier handling parallel 30 A paths with shared cathode thermal management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-60CPH15 | Same TO-220AB package, 60 A total IF(AV), but single-diode structure; VF = 0.82 V @ 30 A, 125 °C | Lacks dual-anode isolation; requires external cathode splitting for dual-rail use | Select when single-output topology suffices and higher VF is acceptable for cost savings |
| ON Semiconductor MUR1520CT | Ultrafast silicon rectifier, 150 V/15 A per diode, VF = 1.15 V, no avalanche rating | Higher conduction loss, lower surge tolerance, unsuitable for high-frequency SMPS above 50 kHz | Only consider for legacy designs where Schottky thermal sensitivity is unacceptable |
Compared with VS-60CPH15 and MUR1520CT, STPS60150CT uniquely combines dual-anode isolation, 0.72 V VF, 1245 W avalanche rating, and 175 °C operation - making it the only option for thermally coupled, high-reliability telecom rectification requiring simultaneous dual-path conduction.

FAQ
What is the maximum continuous forward current per diode at 135 °C case temperature?
The STPS60150CT supports 30 A average forward current per diode at TC = 145 °C. At TC = 135 °C, derating is not required - the device maintains full 30 A per diode rating due to its 175 °C maximum junction temperature and 1.0 °C/W thermal resistance, enabling robust operation in thermally constrained telecom modules.
Can the center tab be left electrically floating during PCB layout?
No. The center tab is the common cathode and must be electrically connected to the system ground or output rail. Leaving it floating creates undefined bias conditions, risks thermal runaway due to uncontrolled heat dissipation, and violates the device's thermal model - which assumes tab-to-heatsink conduction for Rth(j-c) validation.
How does the inter-diode thermal coupling affect parallel operation?
Thermal coupling via Rth(c) = 0.4 °C/W means power dissipated in Diode 2 raises Diode 1's junction temperature by P₂ × 0.4 °C. This necessitates derating both diodes collectively when used simultaneously - e.g., 25 A each instead of 30 A - to maintain Tj ≤ 175 °C, especially in natural-convection environments.
Is STPS60150CT suitable for synchronous rectification circuits?
No. STPS60150CT is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It lacks gate drive logic, timing control, or adaptive dead-time management. It functions as a freewheeling or output rectifier only - synchronous rectification requires active gate-controlled devices like ST's SRK1001 or discrete N-channel MOSFETs with external drivers.
