Product details
Overview
STPS10H100CFP from STMicroelectronics is a dual high-voltage Schottky barrier rectifier in TO-220FPAB package, rated for 100 V repetitive peak reverse voltage, 5 A average forward current per diode at Tc = 160°C, and maximum junction temperature of 175°C. It delivers low forward voltage drop (0.61 V max at 125°C, 5 A), low leakage (<4.5 mA at 125°C), and avalanche-rated power (7200 W at 1 µs) - optimized for compact, high-frequency DC/DC converters in confined thermal environments.
For engineers reviewing the STPS10H100CFP datasheet, STPS10H100CFP pinout, STPS10H100CFP application, or STPS10H100CFP equivalent, key selection criteria include thermal resistance (Rth(j–c) = 4.5 °C/W per diode), surge capability (180 A IFSM), dual-diode configuration with isolated cathodes, and TO-220FPAB's insulated tab for simplified heatsinking without mounting hardware isolation.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V/5 A diodes in a single TO-220FPAB package with electrically isolated metal tab. Its low VF and negligible reverse recovery charge enable high-efficiency operation in 100–500 kHz SMPS topologies where conduction loss minimization is critical.
The device features specified avalanche energy handling (7200 W at 1 µs, 25°C), validated thermal derating curves up to 175°C junction, and low dV/dt sensitivity (10,000 V/µs), supporting robust operation in fast-switching flyback and synchronous rectification auxiliary rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input rectification in 48 V bus-derived DC/DC stages with 2× safety margin |
| IF(AV) per diode | 5 A at Tc = 160°C - enables 10 A total output current with shared thermal path in dual-rail designs |
| VF (max) | 0.61 V at 5 A, 125°C - reduces conduction loss to ~3.05 W per diode at full load |
| Rth(j–c) per diode | 4.5 °C/W - requires ≥12 cm² copper pour on FR4 for ≤60°C rise at 5 A continuous |
| IFSM | 180 A (10 ms sinusoidal) - withstands inrush into bulk capacitors without failure |
| Tj(max) | 175°C - allows operation in sealed enclosures or near hot components without derating |
| IRRM | 1 A at 1 kHz, 2 µs square - ensures stable blocking under high-frequency transient stress |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10BQ100-M3 | Same VRRM (100 V), but single-diode TO-220AC; Rth(j–c) = 3.0 °C/W; no avalanche rating specified | Requires two devices for dual-rail use; lower thermal resistance benefits higher-power single outputs | Select when needing higher single-diode current (10 A avg) and board space permits dual placement |
| ON Semiconductor MBR10100CT | Identical dual common-cathode TO-220AB package; VF = 0.75 V max (25°C); Tj(max) = 150°C; no avalanche spec | Lacks insulated tab - requires insulator kit; lower max junction temp limits high-ambient use | Prefer for cost-sensitive consumer adapters where ambient stays below 60°C and isolation hardware is acceptable |
Compared with VS-10BQ100-M3 and MBR10100CT, STPS10H100CFP uniquely combines insulated-tab packaging, 175°C junction rating, and guaranteed avalanche energy - making it the only option qualified for thermally aggressive, safety-critical industrial and automotive auxiliary supplies without design compromises.

FAQ
What is the thermal resistance from junction to case for each diode in STPS10H100CFP?
The junction-to-case thermal resistance per diode is 4.5 °C/W, measured with the device mounted on a standard heatsink per JEDEC JESD51-14. This value applies when both diodes operate simultaneously; total dissipation must account for coupling via the shared case, adding 2.5 °C/W for cross-heating effects between diodes.
Can STPS10H100CFP replace a single-diode TO-220 rectifier in an existing design?
Yes, but only if the circuit uses a common-cathode configuration and does not require electrical isolation between anodes. STPS10H100CFP contains two independent anodes (A1, A2) and one shared cathode (K). To use one diode, leave the unused anode unconnected; do not short it. The insulated tab allows direct heatsink mounting without additional isolation hardware.
Does STPS10H100CFP support synchronous rectification control?
No - STPS10H100CFP is a passive Schottky rectifier with no gate or control terminals. It operates autonomously based on forward bias conditions. For synchronous rectification, discrete MOSFETs with external gate drivers (e.g., ST's SRK1001 controller + STD80N10F7 MOSFETs) are required; this device serves as a high-efficiency alternative where control complexity must be avoided.
What is the maximum allowable surge current for STPS10H100CFP at 125°C junction temperature?
At Tj = 125°C, the non-repetitive surge forward current (IFSM) remains 180 A for 10 ms sinusoidal waveform, as specified in the datasheet. Derating is not applied to IFSM with temperature - the 180 A rating holds across the full −65°C to +175°C storage range, verified per IEC 61000-4-5 surge test methodology.
