Product details
Overview
STPS1H100MF from STMicroelectronics is a high-voltage Schottky rectifier in STmite Flat package, rated for 100 V repetitive peak reverse voltage and 1 A average forward current at Tc = 160 °C, with max forward voltage drop of 0.62 V at 125 °C and 1 A. It delivers negligible switching losses and avalanche capability up to 108 W (tp = 10 µs), making it suitable for compact DC/DC converters in telecom power supplies.
For engineers reviewing the STPS1H100MF datasheet, STPS1H100MF pinout, STPS1H100MF application, or STPS1H100MF equivalent, key selection criteria include junction-to-case thermal resistance (20 °C/W), low leakage current (≤0.5 mA at 125 °C), and high maximum junction temperature (175 °C) for thermally constrained board-level designs.
Technical Context
This Schottky rectifier uses a planar metal–semiconductor junction optimized for high-frequency operation in switch-mode power supplies. Its design emphasizes low conduction loss via VF ≤ 0.62 V at 1 A/125 °C and robust thermal performance with Rth(j-c) = 20 °C/W, enabling direct mounting on small copper pads without external heatsinks.
The device features specified avalanche capability (108 W, tp = 10 µs, Tj = 125 °C) and operates across -65 to +175 °C storage and junction temperature ranges. Reverse leakage remains tightly controlled - ≤4 µA at 25 °C and ≤0.5 mA at 125 °C under full VRRM - supporting stable performance in high-temperature lighting and telecom applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports input stages in 48 V telecom systems and 24–48 V industrial DC/DC rails without derating |
| IF(AV) | 1 A at Tc = 160 °C - enables continuous conduction mode operation in space-constrained adapters |
| VF (max) | 0.62 V at 1 A, 125 °C - reduces forward conduction loss to ~0.62 W, critical for >90% efficiency targets |
| Tj (max) | 175 °C - allows operation in sealed enclosures or near heat-generating components without thermal shutdown |
| Rth(j-c) | 20 °C/W - permits direct PCB thermal coupling to 2.4 cm² copper area (per Fig. 6) for passive cooling |
| IR (max) | 0.5 mA at 125 °C, VRRM - ensures minimal standby power loss in always-on telecom modules |
| PARM | 108 W (tp = 10 µs) - withstands transient overvoltage events in unregulated input stages |
Pinout & Package
The STPS1H100MF is housed in the STmite Flat surface-mount package (JEDEC MO-232 compatible), measuring 3.80 mm × 1.90 mm × 0.85 mm (E × D × A), with a single anode and cathode terminal configuration. The package uses epoxy meeting UL 94 V0 flammability rating and features exposed metal tab for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Forward current entry point | Exposed metal tab serves as both electrical anode and primary thermal path to PCB copper |
| Cathode (Top-side pad) | Forward current exit / reverse blocking node | Top-surface metallized pad provides low-inductance connection to output rail or filter capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero minority-carrier storage enables operation beyond 1 MHz without recovery-related losses |
| Avalanche capability specified | 108 W surge rating (10 µs pulse) validated per JEDEC JESD22-A110, enabling use without snubbers in flyback primaries |
| High junction temperature capability | Rated for continuous operation up to 175 °C junction, eliminating need for thermal derating in ambient >85 °C |
| Low leakage current | ≤0.5 mA at 125 °C/VRRM - maintains system efficiency in high-temp LED drivers and PoE injectors |
| Good VF/IR trade-off | 0.62 V VF and 0.5 mA IR at 125 °C - balances conduction loss and standby power better than standard 100 V Schottkys |
Applications
| LED Driver Power Stage | Telecom DC/DC Converter Output Rectification |
|---|---|
Use Scenario: Constant-current LED driver for outdoor signage operating at 60–85 °C ambient. IC Role / Device Role / Timing Role: Output rectifier in synchronous buck-derived topology, conducting during low-side switch off-time. Use Value: 0.62 V VF minimizes conduction loss in high-duty-cycle operation; 175 °C Tj(max) avoids thermal throttling under sealed housing conditions. | Use Scenario: 48 V input to 5 V/3.3 V isolated DC/DC module in network edge router. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement, handling 1 A average output current at >300 kHz switching frequency. Use Value: Negligible reverse recovery eliminates switching loss penalty; 20 °C/W Rth(j-c) enables thermal management on 2-layer FR4 without heatsink. |
| Industrial Adapter Input Protection | USB-C PD Power Path Rectification |
Use Scenario: 24 V AC/DC adapter for factory automation I/O modules with wide ambient range (-40 to +75 °C). IC Role / Device Role / Timing Role: Input-stage OR-ing diode protecting against backfeed from auxiliary supplies. Use Value: 100 V VRRM accommodates line transients; ≤4 µA IR at 25 °C prevents battery drain in backup configurations. | Use Scenario: 20 V input rectification in USB-C PD sink circuit with dual-role power negotiation. IC Role / Device Role / Timing Role: Unidirectional power path clamp preventing reverse current flow during source/sink role swap. Use Value: Avalanche rating (108 W) absorbs inductive kickback from PD controller MOSFETs; STmite Flat footprint fits tight 2.5 mm × 4 mm layout constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SB1100-T | Same 100 V VRRM, but VF = 0.85 V (typ.) at 1 A/25 °C; Rth(j-c) = 25 °C/W; no avalanche rating specified | Lacks avalanche capability and higher VF increases conduction loss by ~37% at 125 °C | Acceptable only where transient immunity is managed externally and thermal margin exceeds 5 °C/W |
| Vishay VS-1EH100-M3/5BT | Identical STmite Flat package and 100 V rating; VF = 0.65 V (max) at 1 A/125 °C; IR = 0.6 mA (max) at 125 °C | Slightly higher leakage and VF reduce efficiency margin in sealed telecom modules | Valid drop-in for cost-sensitive designs where 0.03 V VF and 0.1 mA IR differences are acceptable |
Compared with SB1100-T and VS-1EH100-M3/5BT, the STPS1H100MF offers superior thermal robustness (20 °C/W vs ≥25 °C/W), guaranteed avalanche energy handling, and tighter leakage control - critical for high-reliability telecom and industrial power stages.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPS1H100MF is rated for IF(AV) = 1 A at Tc = 160 °C, meaning the case (tab) temperature must not exceed 160 °C under continuous 1 A load. This limit derives from thermal runaway avoidance per condition (dPtot/dTj) < (1/Rth(j-a)), verified with Rth(j-c) = 20 °C/W and recommended 2.4 cm² copper area.
Does STPS1H100MF require a heatsink for 1 A operation?
No external heatsink is required. With Rth(j-c) = 20 °C/W and recommended 2.4 cm² copper pad (FR4, 35 µm Cu), junction temperature stays below 175 °C at 1 A and 70 °C ambient. Figure 6 confirms Rth(j-a) ≈ 4.5 °C/W under those conditions, yielding ΔTj ≈ 45 °C rise.
Is STPS1H100MF suitable for reverse polarity protection?
Yes - its 100 V VRRM and low VF make it effective for low-loss reverse polarity protection in 24–48 V systems. However, the absence of integrated thermal shutdown means external fusing or current limiting is advised for sustained reverse fault conditions exceeding 50 A surge rating.
How does the STmite Flat package compare to SMA or SMC in thermal performance?
STmite Flat offers lower Rth(j-c) (20 °C/W) than SMA (≈35 °C/W) and SMC (≈25 °C/W) due to its exposed anode tab directly bonded to PCB copper. Its 3.8 mm × 1.9 mm footprint also saves >40% board area versus SMC, while maintaining UL 94 V0 compliance unlike many molded packages.
