Product details
Overview
STPS5H100AFY from STMicroelectronics is an automotive-grade high-voltage Schottky rectifier in SOD128Flat package, rated for 100 V repetitive peak reverse voltage and 5 A average forward current, with typical forward voltage drop of 0.51 V at 125 °C and 2.5 A, designed for DC-DC converters and high-frequency SMPS in engine control units and ADAS power supplies.
For engineers reviewing the STPS5H100AFY datasheet, STPS5H100AFY pinout, STPS5H100AFY application, or STPS5H100AFY equivalent, key selection criteria include junction temperature capability up to +175 °C, low leakage current (≤4 mA at 125 °C), avalanche-rated power (300 W at 10 µs), thermal resistance junction-to-lead (16 °C/W), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This Schottky rectifier uses a planar silicon structure optimized for high-voltage operation while maintaining low forward conduction loss and negligible switching losses. Its design enables stable performance across -40 to +175 °C junction temperature range, with reverse leakage tightly controlled (≤4 mA at 125 °C) and avalanche energy capability validated per AEC-Q101 stress conditions.
The SOD128Flat package provides low thermal resistance (Rth(j-l) = 16 °C/W) and supports high-current board-level thermal management via copper surface area under each lead. The device meets ECOPACK® environmental compliance with lead-free finish and UL94 V0 epoxy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage, guaranteed over full -40 to +175 °C operating range |
| IF(AV) | 5 A - average forward current at TL = 115 °C with 50% duty cycle square pulse, defining continuous power handling |
| VF(typ) | 0.51 V @ 2.5 A, 125 °C - low conduction loss enabling high-efficiency 12 V/24 V automotive DC-DC stages |
| Tj(max) | +175 °C - extended junction temperature rating allowing placement near hot engine compartments without derating |
| IR | ≤4 mA @ 125 °C, 100 V - low leakage preserves system standby power budget in always-on vehicle modules |
| PARM | 300 W @ 10 µs - avalanche energy rating supporting transient surge immunity in load-dump scenarios |
| Rth(j-l) | 16 °C/W - thermal resistance from junction to lead, enabling direct PCB copper heatsinking without external heatsink |
Pinout & Package
SOD128Flat is a surface-mount, dual-leaded flat plastic package with exposed cathode and anode terminals. It features low-profile geometry (max height 1.03 mm), UL94 V0 epoxy, and lead-free termination compliant with ECOPACK® standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to input rail (e.g., battery or boost stage output); requires adequate copper pour for thermal dissipation |
| Cathode (K) | Forward current exit point / common reference | Connected to ground or output node; serves as primary thermal path to PCB copper due to exposed metal pad |
Key Features

|---|---|
| Negligible switching losses | Enables >95% efficiency in 200–500 kHz automotive DC-DC converters without reverse recovery penalty |
| Avalanche specification | Rated for 300 W single-pulse avalanche energy at 10 µs, supporting ISO 7637-2 load-dump transient robustness |
| AEC-Q101 qualified | Validated for automotive under-hood applications including ECU, body control modules, and infotainment power rails |
| Low leakage at high temperature | ≤4 mA at 125 °C ensures minimal standby current drain in always-on vehicle subsystems |
| ECOPACK® compliant | Lead-free, halogen-free, RoHS-compliant construction with UL94 V0 flammability rating |
Applications
| Engine Control Unit (ECU) Power Supply | ADAS Camera Module DC-DC Converter |
|---|---|

IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier in secondary-side synchronous buck converter. Use Value: Low VF (0.51 V) and high Tj(max) (+175 °C) reduce conduction loss and eliminate thermal derating, extending ECU lifetime. | Use Scenario: Providing isolated 5 V supply for image sensor and ISP in front-facing ADAS cameras mounted behind windshield. IC Role / Device Role / Timing Role: Output rectifier in flyback or forward converter operating at 300 kHz switching frequency. Use Value: Negligible reverse recovery and low leakage (<4 mA at 125 °C) prevent noise coupling into analog imaging chain and preserve low-power sleep mode. |

Use Scenario: Generating 12 V auxiliary rail from 48 V mild-hybrid bus for display backlighting and audio amplifiers. IC Role / Device Role / Timing Role: Secondary-side rectifier in high-frequency LLC resonant converter. Use Value: Avalanche rating (300 W) withstands 12 V bus transients during start-stop cycling; SOD128Flat footprint enables compact layout. | Use Scenario: Converting 12 V battery to regulated 5 V for EPS microcontroller and motor gate drivers in steering column assembly. IC Role / Device Role / Timing Role: Output rectifier in compact buck-derived isolated supply. Use Value: Rth(j-l) = 16 °C/W allows direct thermal coupling to EPS housing, eliminating need for discrete heatsink in space-constrained module. |
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 |
|---|---|---|---|
| ON Semiconductor NSS10100CTG | 100 V, 10 A dual common-cathode; higher IF(AV), larger TO-252 package, no AEC-Q101 certification | Requires board space for TO-252; not qualified for automotive safety-critical modules | Select when higher current (10 A) is needed and AEC-Q101 is not required |
| Vishay VS-5EY100-M3 | 100 V, 5 A; same SOD128 package; VF = 0.62 V @ 2.5 A, 125 °C; no avalanche rating or PPAP support | Lacks avalanche energy spec and PPAP documentation, limiting use in load-dump-prone systems | Select for cost-sensitive non-safety automotive or industrial DC-DC where avalanche immunity is not mandated |
Compared with NSS10100CTG and VS-5EY100-M3, STPS5H100AFY uniquely combines AEC-Q101 qualification, 300 W avalanche rating, and 0.51 V low-VF performance in the compact SOD128Flat package-making it the only option qualified for safety-critical, thermally constrained automotive power conversion.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The STPS5H100AFY has a maximum operating junction temperature of +175 °C, verified per AEC-Q101 stress testing. Continuous operation at this temperature requires adherence to the thermal design condition (dPtot/dTj) < (1/Rth(j-a)) to prevent thermal runaway, typically achieved using ≥4 cm² of 35 µm copper per lead on FR4 PCB.
Does STPS5H100AFY support PPAP documentation for automotive production?
Yes, STPS5H100AFY is PPAP-capable per the official ST datasheet (DocID029453 Rev 2). ST provides full PPAP Level 3 documentation-including part submission warrant, design records, process flow diagrams, control plans, and measurement system analysis-upon request for qualified automotive customers.
How does the avalanche rating translate to real-world circuit protection?
The 300 W avalanche rating at 10 µs corresponds to withstanding a 100 V, 3 A transient for 10 µs without failure. This directly supports compliance with ISO 7637-2 Pulse 5a (load dump), where peak energy can reach ~200–250 W in typical 12 V harness configurations, providing margin against clamping diode failure.
Is the SOD128Flat package compatible with standard reflow profiles?
Yes, STPS5H100AFY's SOD128Flat package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for 30 seconds. Its UL94 V0 epoxy and lead-free terminations ensure compatibility with standard Class 3 automotive PCB assembly processes without delamination or solder joint reliability issues.
