Product details
Overview
STPS61H100CW from STMicroelectronics is a dual common-cathode Schottky rectifier in TO-247 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 drop of 0.63 V at 125 °C and 30 A - optimized for high-frequency SMPS in telecom and desktop power supplies.
For engineers reviewing the STPS61H100CW datasheet, STPS61H100CW pinout, STPS61H100CW application, or STPS61H100CW equivalent, key selection criteria include junction-to-case thermal resistance (0.9 °C/W per diode), low leakage (≤4 mA at 125 °C), ECOPACK®2 compliance, and dual-diode thermal coupling behavior under simultaneous conduction.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous or interleaved rectification topologies without external parallel wiring. Its low VF and low Rth(j-c) support high-efficiency operation at switching frequencies up to several hundred kHz in continuous conduction mode.
The thermal architecture accounts for mutual heating: when both diodes conduct simultaneously, junction temperature rise of Diode 1 depends on its own power plus 30% of Diode 2's power due to coupling resistance (Rth(c) = 0.3 °C/W), requiring coordinated thermal design rather than isolated derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input stages of 48 V telecom systems and 36–75 V intermediate bus converters without avalanche stress |
| IF(AV) per diode | 30 A at Tc = 150 °C - enables compact heatsink sizing in high-power density DC/DC modules |
| VF(typ) | 0.63 V at 30 A, 125 °C - reduces conduction loss to ~18.9 W per diode versus silicon alternatives (>1.1 V) |
| IR(max) | 4 mA at 125 °C, VR = 100 V - limits standby power loss in always-on telecom power units |
| Rth(j-c) per diode | 0.9 °C/W - allows direct mounting to heatsink with ≤27 °C temperature rise at full 30 A load |
| Tj(max) | +175 °C - extends operational margin in sealed enclosures with limited airflow |
| ECOPACK®2 | RoHS-compliant, halogen-free epoxy - meets IPC-1752A Tier 1 reporting and EU Ecodesign requirements |
Pinout & Package
TO-247 package with three terminals: Anode 1 (pin 1), Cathode (pin 2, common), Anode 2 (pin 3). Mounting via heat-sink plane (backside metal tab); recommended torque 0.8 N·m (max 1.0 N·m).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (A1) | Anode of Diode 1 | Connects to high-side switch node in half-bridge synchronous rectifier or first phase of interleaved output stage |
| Pin 2 (K) | Common cathode | Single low-inductance return path for both diodes; must be routed with minimal loop area to reduce EMI in >100 kHz designs |
| Pin 3 (A2) | Anode of Diode 2 | Connects to second switch node in dual-phase topology or auxiliary rail in multi-output SMPS |
Key Features
| Feature | Design Value |
|---|---|
| High junction temperature capability | Rated for continuous operation up to +175 °C junction - eliminates need for oversized heatsinks in thermally constrained telecom bricks |
| Low thermal resistance | Rth(j-c) = 0.9 °C/W per diode - enables 30 A conduction with <27 °C ΔT over heatsink, improving system efficiency by ~0.8% at full load |
| Controlled leakage–VF trade-off | IR ≤ 4 mA at 125 °C / 100 V while maintaining VF ≤ 0.67 V - balances standby loss and conduction loss in 24/7 powered equipment |
| ECOPACK®2 compliance | Halogen-free, RoHS-compliant molding compound - satisfies IEC 61249-2-21 and JEDEC J-STD-020 reflow requirements without process change |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS60H100CW | Same TO-247 package, but IF(AV) = 2 × 30 A at Tc = 145 °C (not 150 °C); VF = 0.65 V typ at 125 °C | Lower thermal margin - requires larger heatsink or reduced ambient in sealed enclosures | Select when cost sensitivity outweighs 5 °C junction margin and board space permits minor thermal redesign |
| Vishay VS-60CPH10-M3 | TO-247AC package, IF(AV) = 2 × 30 A at Tc = 135 °C, VF = 0.72 V typ at 125 °C, Rth(j-c) = 1.1 °C/W | Higher VF and thermal resistance increase conduction loss by ~14% and require +12 °C higher heatsink temp at same load | Choose only if ST supply chain constraints exist and thermal budget allows 12 °C additional ΔT |
Compared with STPS60H100CW and VS-60CPH10-M3, STPS61H100CW delivers the highest thermal margin (175 °C Tj max) and lowest VF–Rth combination, making it optimal for high-reliability telecom and server power where junction temperature stability directly impacts MTBF.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF(AV) = 30 A per diode at Tc = 150 °C. Exceeding this temperature requires derating per Figure 2; at Tc = 160 °C, maximum IF(AV) drops to ~24 A per diode. Operation beyond 150 °C case temperature is not supported for rated current.
Can STPS61H100CW be used in avalanche mode?
No - this Schottky rectifier is not rated for repetitive avalanche operation. The PARM rating (1900 W at tp = 10 µs) applies only to single-pulse transient suppression; sustained reverse bias above VRRM risks irreversible junction damage due to lack of controlled avalanche breakdown mechanism.
How does thermal coupling affect simultaneous conduction of both diodes?
When both diodes conduct, Diode 1's junction temperature rise equals P₁ × 0.9 + P₂ × 0.3 °C, where P₁ and P₂ are respective powers. This 30% coupling factor means shared heatsinking must account for combined dissipation, not just sum of individual Rth(j-c) values.
Is the TO-247 package lead-free and RoHS-compliant?
Yes - STPS61H100CW carries ECOPACK®2 certification, confirming lead-free terminations, halogen-free epoxy, and full compliance with EU RoHS Directive 2011/65/EU and REACH SVHC requirements as verified in ST's official product documentation.
