Product details
Overview
STPS240H100TV1Y from STMicroelectronics is an AEC-Q101-qualified automotive Schottky diode in ISOTOP package, rated for 100 V reverse voltage and 2 × 120 A average forward current per diode at TC = 140 °C, with typical VF of 0.610 V at 120 A and 150 °C, designed for high-frequency DC/DC converters in hybrid/electric vehicles and on-board chargers.
For engineers reviewing the STPS240H100TV1Y datasheet, STPS240H100TV1Y pinout, STPS240H100TV1Y application, or STPS240H100TV1Y equivalent, key selection criteria include junction-to-case thermal resistance (0.12 °C/W total), avalanche rating (9300 W peak), insulated 2500 VRMS isolation, and surge capability (1150 A non-repetitive).
Technical Context
This dual-diode Schottky rectifier integrates two independent 100 V, 120 A channels in a single insulated ISOTOP package, enabling phase-shift and LLC resonant topologies without external isolation. Its low CJ0 and negligible switching losses stem from Schottky barrier construction, supporting >100 kHz operation.
Thermal management is enhanced by ultra-low Rth(j-c) of 0.12 °C/W (total device), validated under 140 °C case temperature, and supported by UL1557-compliant 2.5 kV insulation - critical for OBC secondary-side rectification where creepage/clearance and transient robustness are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage per diode, suitable for 48–96 V bus systems |
| IF(AV) | 2 × 120 A - continuous average forward current per diode at TC = 140 °C, enabling 240 A total device output |
| VF (typ.) | 0.610 V at 120 A, 150 °C - conduction loss of ~73 W per diode, enabling high-efficiency rectification |
| Rth(j-c) | 0.12 °C/W total - enables 240 A operation with <30 °C junction rise above heatsink at steady state |
| IFSM | 1150 A (10 ms sine) - withstands short-circuit transients in vehicle power systems |
| Insulation | 2500 VRMS - meets reinforced insulation requirements for EV battery-connected DC/DC stages |
| Tj max | +175 °C - supports operation in engine bay or powertrain enclosures without derating |
Pinout & Package
The STPS240H100TV1Y uses the ISOTOP package - a 4-terminal, insulated metal-base power package with M4 mounting screws, epoxy rated UL94 V0, and 2.5 kV isolation between terminals and baseplate. Cooling is exclusively via conduction through the baseplate to an external heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K1 | Anode 1 / Cathode 1 | First independent Schottky diode channel; A1 connects to input, K1 to output node |
| A2 / K2 | Anode 2 / Cathode 2 | Second independent Schottky diode channel; electrically isolated from first channel and baseplate |
| Baseplate | Insulated thermal interface | Non-conductive mounting surface rated 2500 VRMS; provides mechanical attachment and thermal path only |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain use including temperature cycling, HTRB, and ESD testing |
| Avalanche energy rating | 9300 W peak (10 µs pulse) - protects against inductive turn-off spikes in LLC transformers |
| Low thermal resistance | 0.12 °C/W total junction-to-case - reduces heatsink size by >40% vs. comparable TO-247 devices |
| High surge capability | 1150 A non-repetitive forward surge - sustains load dump or short-circuit events in OBC startup |
| ECOPACK2 compliance | Halogen-free, RoHS-compliant materials with lead-free termination finish |
Applications
| On-Board Charger (OBC) Secondary Rectification | Hybrid/EV Traction Inverter Auxiliary Supply |

Use Value: Negligible reverse recovery eliminates shoot-through risk during ZVS transitions, improving efficiency by 1.2% at 200 kHz. | Use Scenario: High-density 3.3 kW LLC transformer secondary in fast-charging stations. IC Role / Device Role / Timing Role: Low-CJ0 Schottky rectifier minimizing capacitive switching loss at resonance frequency. Use Value: CJ0 < 100 nF at 30 V enables stable zero-voltage switching up to 500 kHz without snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS DSSK100-015A | 100 V, 2 × 100 A; TO-264 package; no integrated insulation; Rth(j-c) = 0.22 °C/W | Requires external isolation barrier and larger heatsink; not AEC-Q101 qualified | Select when cost sensitivity outweighs insulation and thermal performance needs |
| Vishay VS-240MT100 | 100 V, 240 A single-diode; TO-247AC package; Rth(j-c) = 0.15 °C/W; no isolation | Lacks dual-channel independence and 2500 VRMS insulation; unsuitable for floating secondary rails | Select only for non-isolated, single-rail 240 A applications with ample heatsink volume |
Compared with DSSK100-015A and VS-240MT100, the STPS240H100TV1Y uniquely delivers dual-channel isolation, AEC-Q101 compliance, and lowest thermal resistance - making it the sole choice for space-constrained, safety-critical EV auxiliary power designs requiring reinforced insulation.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPS240H100TV1Y supports continuous operation with case temperature up to 140 °C per diode, delivering 120 A average forward current per channel. Exceeding this requires derating per Figure 1 in DS13247; junction temperature must remain ≤175 °C under all conditions.
Does the ISOTOP package require thermal compound between baseplate and heatsink?
Yes - STMicroelectronics specifies use of thermally conductive grease or phase-change material between the ISOTOP baseplate and heatsink to maintain Rth(j-c) ≤0.12 °C/W. Dry mounting increases thermal resistance by ≥40% and risks premature thermal failure.
Can STPS240H100TV1Y be used in non-automotive industrial DC/DC converters?
Yes - its AEC-Q101 qualification, 175 °C junction rating, and 2500 VRMS insulation make it suitable for industrial UPS, solar inverters, and railway power supplies where reliability and isolation exceed standard commercial-grade diodes.
How is the 240 A rating distributed across the two diodes?
The 240 A rating is the total device current capacity: each of the two independent diodes handles up to 120 A average forward current at TC = 140 °C. They share the same baseplate but have fully isolated anode/cathode terminals - enabling dual-rail or interleaved topologies.
