Product details
Overview
STPS60H100CT from STMicroelectronics is a dual common-cathode Schottky rectifier in TO-220AB package, rated for 100 V repetitive peak reverse voltage and 2 × 30 A average forward current per diode at Tc = 150 °C, with typical forward voltage of 0.67 V at 125 °C and 30 A - optimized for high-frequency SMPS in telecom and desktop power supplies.
For engineers reviewing the STPS60H100CT datasheet, STPS60H100CT pinout, STPS60H100CT application, or STPS60H100CT equivalent, key selection criteria include low thermal resistance (Rth(j–c) = 1.0 °C/W per diode), avalanche capability (1300 W, tp = 10 µs), ECOPACK®2 compliance, and verified performance up to 175 °C junction temperature.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous rectification or dual-channel output in DC/DC converters. Its low VF and fast switching minimize conduction and recovery losses, while the TO-220AB package provides direct heatsink mounting for efficient thermal management.
The diode pair supports parallel operation with coupled thermal behavior: junction temperature rise of Diode 1 depends on both its own power dissipation and Diode 2's via coupling resistance (Rth(c) = 0.4 °C/W), requiring coordinated layout and heatsinking for balanced thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage per diode; defines safe operating range in 48 V telecom and 12/24 V industrial DC/DC outputs. |
| IF(AV) per diode | 30 A at Tc = 150 °C - continuous forward current rating per diode under heatsink-cooled conditions; enables 60 A total device output with shared cathode. |
| VF(typ) | 0.67 V at 30 A, 125 °C - low conduction loss reduces power dissipation by ~20% vs. comparable 0.84 V diodes at same current and temperature. |
| Rth(j–c) per diode | 1.0 °C/W - thermal resistance from junction to case; allows direct calculation of junction temperature rise under known power load and heatsink interface. |
| IFS M | 300 A (tp = 10 ms) - non-repetitive surge current capability; sustains short-term overload transients without failure in server PSU inrush scenarios. |
| Tj(max) | +175 °C - maximum junction temperature; supports operation in sealed enclosures or high-ambient environments without derating below full current. |
| IR(max) | 10 mA at 125 °C, VR = VRRM - low leakage preserves efficiency in standby mode and reduces thermal runaway risk in parallel configurations. |
Pinout & Package
Package: TO-220AB - insulated plastic case with metal tab (cathode-connected), designed for mechanical mounting to heatsinks using 0.55 N·m torque; UL 94 V0 epoxy, 1.95 g unit weight, tube packaging (50 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab / Pin 1 | Common Cathode | Electrically connected to metal tab; must be isolated from heatsink unless referenced to system ground; primary thermal path to heatsink. |
| Pin 2 | Anode 1 | Input terminal for first diode; used for main output rectification or auxiliary rail generation. |
| Pin 3 | Anode 2 | Input terminal for second diode; enables dual-output or phase-interleaved converter topologies without external cathode tie. |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | Rated for continuous operation up to +175 °C junction temperature - eliminates need for oversized heatsinks in compact, sealed power modules. |
| Low thermal resistance | Rth(j–c) = 1.0 °C/W per diode - enables >90% of rated current utilization with standard TO-220 heatsinks at 60 °C ambient. |
| Avalanche energy rating | 1300 W peak avalanche power (tp = 10 µs, Tj = 125 °C) - withstands inductive turn-off spikes in synchronous buck converters without snubber circuits. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements - qualified for automotive and industrial applications requiring strict environmental certification. |
| Low leakage current | Max 10 mA IR at 125 °C and full VRRM - minimizes standby power loss and improves reliability in high-temperature backup power systems. |
Applications

IC Role / Device Role / Timing Role: Dual-anode configuration supports redundant +12 V rails or split-load distribution across two transformer secondaries. Use Value: Avalanche rating (1300 W) absorbs transformer leakage energy during MOSFET turn-off, eliminating need for clamp diodes and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-60CPH10 | Same TO-220AB package, 100 V VRRM, but single-diode; IF(AV) = 60 A (single anode), VF = 0.72 V @ 30 A, 125 °C. | Lacks common-cathode dual configuration - requires external cathode tie for dual-rail use, increasing layout complexity and parasitic inductance. | Select when only one high-current rail is needed and board space permits discrete cathode routing. |
| ON Semiconductor MBR60100CT | TO-220AB, 100 V, 2 × 30 A, VF = 0.82 V @ 30 A, 25 °C; Rth(j–c) = 1.2 °C/W; no specified avalanche rating. | Higher VF increases conduction loss by ~4.5 W per diode at full load; lacks documented avalanche capability for spike suppression. | Select where cost sensitivity outweighs efficiency and robustness requirements in non-critical consumer power supplies. |
Compared with VS-60CPH10 and MBR60100CT, STPS60H100CT uniquely combines dual common-cathode integration, lowest VF (0.67 V), best thermal resistance (1.0 °C/W), and certified avalanche energy - making it optimal for high-density, high-reliability telecom and server power designs.

FAQ
Is STPS60H100CT suitable for synchronous rectification in LLC resonant converters?
Yes - its low VF (0.67 V typ. at 30 A, 125 °C), fast recovery (Schottky), and 175 °C Tj(max) make it suitable for secondary-side synchronous rectification in LLC converters operating up to 500 kHz. The common-cathode configuration simplifies gate drive referencing and reduces layout parasitics versus discrete diodes.
What is the recommended heatsink interface for STPS60H100CT in TO-220AB package?
Mount the metal tab directly to a heatsink using thermal interface material (TIM) and torque the M3 screw to 0.55 N·m (max 0.70 N·m). Ensure electrical isolation if the cathode is not at system ground; use UL 94 V0-compliant insulating washers and TIM with thermal conductivity ≥1.5 W/m·K for optimal Rth(j–a) performance.
Does STPS60H100CT require snubber circuits in high-dI/dt applications?
No - its 1300 W avalanche rating (tp = 10 µs, Tj = 125 °C) allows it to absorb inductive turn-off energy without external snubbers in typical buck or flyback topologies. However, layout optimization (short traces, minimized loop area) remains critical to avoid voltage overshoot beyond VRRM.
How does thermal coupling affect derating when both diodes operate simultaneously?
When both diodes conduct, junction temperature rise of Diode 1 equals P₁ × 1.0 °C/W + P₂ × 0.4 °C/W due to thermal coupling (Rth(c) = 0.4 °C/W). Therefore, simultaneous full-load operation (30 A each) raises Tj by ~42 °C above case temperature - requiring derating or enhanced heatsinking to stay within 175 °C limit.
