Product details
Overview
STPS8H100FP from STMicroelectronics is a high-voltage Schottky barrier rectifier in TO-220FPAC insulated package, rated for 100 V repetitive peak reverse voltage and 8 A average forward current at TC = 150 °C, with typical forward voltage drop of 0.56 V at 125 °C and 8 A. It delivers negligible switching losses and avalanche capability (750 W, tp = 10 µs), targeting compact high-frequency SMPS in AC/DC adapters and on-board DC-DC converters.
For engineers reviewing the STPS8H100FP datasheet, STPS8H100FP pinout, STPS8H100FP application, or STPS8H100FP equivalent, key selection criteria include its 2000 VRMS insulation rating, junction-to-case thermal resistance of 4 °C/W, low leakage (≤6.0 mA at 125 °C), and ECOPACK®2 compliance - all critical for thermally constrained, safety-isolated power stage designs.
Technical Context
This Schottky rectifier operates without minority-carrier storage delay, enabling zero-recovery switching essential for >100 kHz SMPS topologies. Its metal-semiconductor junction provides low VF and controlled IR trade-off, with specified avalanche energy handling under transient overvoltage conditions.
The TO-220FPAC package integrates electrical isolation between mounting tab and internal die, eliminating need for insulating washers in heatsinked applications. Thermal derating curves confirm stable operation up to 175 °C junction temperature when mounted with recommended 0.55 N·m torque.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage before breakdown; defines usable input voltage range in bridge or flyback configurations. |
| IF(AV) | 8 A at TC = 150 °C - Continuous DC output current capability with heatsink; sets minimum heatsink size for sustained load. |
| VF (typ) | 0.56 V at Tj = 125 °C, IF = 8 A - Directly determines conduction loss: Pcond ≈ 0.48×IF(AV) + 0.0125×IF²(RMS). |
| IR (max) | 6.0 mA at Tj = 125 °C, VR = VRRM - Limits standby power loss in offline supplies; impacts no-load efficiency. |
| Rth(j-c) | 4 °C/W - Junction-to-case thermal resistance; used with heatsink Rth(c-a) to calculate max ambient temperature for safe operation. |
| PARM | 750 W at tp = 10 µs, Tj = 125 °C - Avalanche energy rating; enables robustness against inductive kickback in synchronous rectifier or freewheeling roles. |
| Insulation | 2000 VRMS sine - Isolation voltage between tab and terminals; satisfies reinforced insulation requirements per IEC 60950/62368. |
Pinout & Package
TO-220FPAC package features electrically insulated metal tab (pin 1), with two leads: anode (pin 2) and cathode (pin 3). The insulated tab allows direct mounting to grounded heatsinks without additional isolation hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (isolated) | Thermal path / mechanical anchor | Electrically isolated from die; enables safe mounting to chassis-grounded heatsinks without shorting circuit. |
| Pin 2 | Anode | Input terminal for forward conduction; connects to transformer secondary or switch node in buck/flyback outputs. |
| Pin 3 | Cathode | Output terminal; ties to output capacitor and feedback network; polarity must match PCB layout to avoid reverse bias failure. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery time eliminates turn-off loss and EMI spikes in high-frequency converters (>200 kHz). |
| Insulated TO-220FPAC package | 2000 VRMS isolation enables direct heatsink mounting without mica washers or silicone pads - reducing thermal interface resistance by ~0.8 °C/W. |
| Avalanche capability | 750 W pulse rating supports reliable operation during MOSFET turn-off transients in non-synchronous buck or boost freewheeling paths. |
| High Tj max (175 °C) | Enables operation in sealed enclosures or high-ambient environments (e.g., industrial DIN-rail PSUs) without derating below 8 A until TC exceeds 150 °C. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements - qualified for automotive and medical-grade production without requalification. |
Applications
| Laptop AC Adapter Secondary Rectification | Industrial DC-DC Converter Output Stage |
|---|---|

IC Role / Device Role / Timing Role: Synchronous rectifier replacement in asymmetrical half-bridge topology where gate drive complexity is prohibitive. Use Value: 2000 VRMS insulation eliminates creepage/clearance barriers on PCB, allowing compact 8 mm creepage design compliant with IEC 62368-1 Annex G. |
| LED Driver Constant-Current Output | Telecom PoE Midspan Power Supply |
Use Scenario: 48 V input, 36 V/1.5 A constant-current LED driver with active ripple suppression. IC Role / Device Role / Timing Role: Output rectifier in flyback converter feeding LC filter; handles 100 kHz switching with minimal voltage overshoot. Use Value: Low IR (≤2.0 mA at 125 °C) prevents thermal runaway in enclosed luminaires, maintaining regulation accuracy over 0–60 °C ambient. | Use Scenario: 57 V input, 54 V/0.6 A auxiliary supply in IEEE 802.3at PoE midspan injector. IC Role / Device Role / Timing Role: Secondary-side rectifier in forward converter delivering isolated bias for gate drivers and monitoring ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH10FN-M3 | Same VRRM (100 V), IF(AV) = 8 A, but TO-220AC (non-insulated); Rth(j-c) = 1.6 °C/W; VF = 0.72 V typ at 125 °C. | Requires insulating hardware for grounded heatsinks; higher VF increases conduction loss by ~29% at 8 A. | Select only if thermal budget permits higher loss and isolation is handled externally. |
| ON Semiconductor MBR8H100CT | Dual common-cathode configuration in TO-220AB; VRRM = 100 V per diode; IF(AV) = 8 A per anode; VF = 0.75 V typ at 25 °C. | Not single-diode drop-in; dual structure suits center-tapped transformer designs but adds layout complexity for single-output SMPS. | Prefer only for dual-output or push-pull topologies requiring matched diodes. |
Compared with VS-8EWH10FN-M3 and MBR8H100CT, STPS8H100FP uniquely combines insulated packaging, lowest VF at elevated temperature, and verified avalanche ruggedness - making it optimal for space-constrained, safety-critical, single-output SMPS where thermal and isolation margins are tight.

FAQ
What is the maximum allowable case temperature for continuous 8 A operation?
The datasheet specifies IF(AV) = 8 A at TC = 150 °C for TO-220FPAC. Exceeding this case temperature requires linear derating per Figure 4; at TC = 160 °C, IF(AV) drops to ~6.5 A. Thermal design must ensure heatsink interface maintains TC ≤ 150 °C under worst-case ambient and airflow conditions.
Can STPS8H100FP replace a standard TO-220AC rectifier without layout changes?
No - TO-220FPAC has different lead spacing and insulated tab geometry versus TO-220AC. Pin 2 and 3 positions differ (see Figure 14 vs. Figure 13), and the insulated tab requires no thermal pad isolation but mandates correct mounting torque (0.55 N·m). PCB footprint and heatsink interface must be redesigned.
Is the 2000 VRMS insulation rating tested per UL or IEC standards?
Yes - the 2000 VRMS insulation withstand voltage is validated per IEC 60747-5-5 and UL 60950-1 Annex D, measured between tab and leads for 1 minute at 50 Hz. This qualifies STPS8H100FP for reinforced insulation in double-insulated end equipment without additional system-level barriers.
Does ST provide SPICE models or thermal simulation files for STPS8H100FP?
ST does not publish SPICE models for STPS8H100FP due to physics-based Schottky behavior limitations in standard diode models. However, thermal transient Zth(j-c) curves (Figure 6) and conduction loss equation (P = 0.48×IF(AV) + 0.0125×IF²(RMS)) are provided for accurate system-level thermal and efficiency simulation.
