Product details
Overview
STPS3060CW from STMicroelectronics is a high-voltage dual Schottky rectifier in TO-247 package, designed for medium-voltage, high-frequency switchmode power supplies. It delivers 30 A RMS forward current per diode, 60 V repetitive peak reverse voltage, and 0.75 V max forward voltage at 15 A/125°C - enabling low conduction loss in DC-DC converters and AC-DC front-ends.
For engineers reviewing the STPS3060CW datasheet, STPS3060CW pinout, STPS3060CW application, or STPS3060CW equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (1.5 °C/W per diode), surge current capability (200 A non-repetitive), and low-noise switching performance in PFC and synchronous rectification stages.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 60 V / 30 A diodes sharing a single TO-247 heatsinkable case. Its negligible switching losses stem from zero minority-carrier storage and low junction capacitance (≈40 pF at 30 V), making it suitable for >100 kHz operation in resonant LLC and active clamp flyback topologies.
The device features a critical dV/dt rating of 1000 V/µs and avalanche-rated reverse surge capability (1 A repetitive, 1 A non-repetitive), supporting robust operation under transient overvoltage conditions without external snubbers in industrial SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum blocking voltage per diode; defines usable input range in 48 V–54 V bus applications |
| IF(RMS) | 30 A per diode - supports continuous output currents up to 30 A in parallel-diode configurations |
| VF (max) | 0.75 V at 15 A / 125°C - enables <1.2 W conduction loss per diode at full rated load |
| IFS M | 200 A (tp = 10 ms) - withstands short-duration overload events in UPS and motor drive DC links |
| Rth(j-c) | 1.5 °C/W per diode - allows direct mounting to heatsink with predictable thermal rise under 45 W dissipation |
| CJ | ≈40 pF at VR = 30 V - minimizes capacitive switching noise and EMI in high-dV/dt gate-drive circuits |
| dV/dt | 1000 V/µs - ensures stable reverse recovery without false turn-on in fast-switching half-bridge legs |
Pinout & Package
TO-247 package with three terminals: Cathode (shared, tab-connected), Anode 1, and Anode 2. The metal tab is electrically connected to the common cathode and serves as primary thermal path. Mounting torque: 0.8 N·m recommended (max 1.0 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Case) | Common Cathode | Electrically and thermally tied to both diodes' cathodes; requires insulating washer if mounted to grounded heatsink |
| Lead 1 | Anode 1 | Independent anode for first Schottky diode; used in dual-output or interleaved converter phases |
| Lead 2 | Anode 2 | Independent anode for second Schottky diode; enables shared cathode topology for reduced layout parasitics |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode configuration | Reduces PCB trace inductance and enables compact dual-phase rectification without external node tying |
| Low VF temperature coefficient | VF drops from 0.85 V (25°C) to 0.65 V (125°C) at 15 A - improves efficiency under thermal stress |
| High dV/dt immunity | 1000 V/µs rating prevents spurious conduction during fast voltage transients in SiC/GaN-based converters |
| Avalanche-rated reverse surge | Withstands 1 A non-repetitive reverse current (100 µs) - eliminates need for external TVS in cost-sensitive industrial PSUs |
| UL94-V0 epoxy package | Meets flammability requirements for enclosed power systems without additional potting or shielding |
Applications
| Server PSU Rectification | Industrial DC-DC Converter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 48 V input, 12 V/30 A output server power supply modules. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier replacing MOSFETs in OR-ing and freewheeling paths; operates at 300–500 kHz.

IC Role / Device Role / Timing Role: High-reliability dual-diode rectifier handling 30 A RMS input ripple current with minimal EMI generation. Use Value: 40 pF junction capacitance limits high-frequency ringing, easing EMC filter design and reducing snubber losses. |
| Solar Microinverter DC Link | Telecom Rectifier Module |
Use Scenario: DC link clamping and freewheeling in 600 V-class solar microinverters using interleaved boost stages. IC Role / Device Role / Timing Role: Dual-diode configured as back-to-back clamp pair across split-rail DC bus; handles bidirectional surge energy.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H60CG | Same TO-247 package, but uses hyperfast silicon process; VF ≈ 0.95 V at 15 A/125°C | Higher forward drop increases conduction loss; preferred only where higher VRRM (100 V) is required | Select when system requires >60 V blocking margin or legacy silicon compatibility |
| Vishay VS-30CPH06-M3 | TO-247 package, dual common-cathode, VF = 0.72 V at 15 A/125°C, but Rth(j-c) = 1.8 °C/W | Higher thermal resistance limits power density; less suitable for space-constrained 30 A designs | Select when lower VF priority outweighs thermal derating needs, e.g., forced-air cooled systems |
Compared with STPS3060CW, STPS30H60CG trades lower switching noise for higher conduction loss, while VS-30CPH06-M3 offers marginally lower VF but sacrifices thermal performance - making STPS3060CW optimal for thermally constrained, high-frequency 60 V rectification.

FAQ
Is the STPS3060CW RoHS compliant?
Yes, STPS3060CW is RoHS compliant and lead-free per EU Directive 2011/65/EU. The TO-247 package uses matte tin-plated leads and UL94-V0 epoxy, with no exemptions applied. Full compliance documentation is available upon request for qualifying orders.
Can STPS3060CW be used in parallel with another unit for higher current?
No - STPS3060CW is not characterized for parallel operation due to thermal coupling between diodes in the shared TO-247 case. For >30 A applications, use separate discrete Schottky diodes with individual thermal paths or select a higher-current single-die part.
What is the maximum allowable case temperature during continuous operation?
The maximum case temperature is limited by junction temperature: Tj(max) = 150°C. With Rth(j-c) = 1.5 °C/W per diode and 30 A RMS, case temperature must remain ≤105°C to maintain safe margin, assuming worst-case thermal interface resistance and ambient conditions.
Does the common cathode require isolation from the heatsink?
Yes - the metal tab (cathode) is electrically active. When mounting to a grounded heatsink, a UL-certified insulating washer and shoulder washer must be used to prevent short-circuiting. Thermal paste must be non-conductive and applied only to the isolated surface.
