Product details
Overview
STPS200170TV1Y from STMicroelectronics is a dual 100 A, 170 V high-voltage Schottky rectifier in ISOTOP package, designed for secondary-side rectification in high-frequency DC/DC converters used in hybrid and electric vehicles. It features 0.63 V typical forward voltage at 150 °C, 2500 VRMS insulation rating, and AEC-Q101 qualification for automotive under-hood operation.
For engineers reviewing the STPS200170TV1Y datasheet, STPS200170TV1Y pinout, STPS200170TV1Y application, or STPS200170TV1Y equivalent, key selection criteria include junction-to-case thermal resistance (0.4 °C/W per diode), avalanche power rating (7200 W), leakage current (≤100 mA at 125 °C), and insulated package compliance with UL1557.
Technical Context
This device integrates two independent Schottky diodes in a single insulated ISOTOP housing, enabling dual-channel high-current rectification without external isolation. Its low VF–IR trade-off supports efficient operation up to 175 °C junction temperature while maintaining negligible switching losses in LLC and phase-shift resonant topologies.
The 2500 VRMS reinforced insulation between die and heatsink allows direct mounting on conductive chassis in automotive traction inverters and onboard chargers. Avalanche rating and PPAP capability confirm suitability for safety-critical power conversion stages where transient overvoltage resilience and production traceability are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per diode | 100 A at TC = 140 °C - supports continuous high-current output in dual-phase DC/DC converters |
| VRRM | 170 V - enables use in 48 V–96 V battery-derived systems with margin against transients |
| VF (typ.) | 0.63 V at IF = 100 A, Tj = 150 °C - reduces conduction loss by ~30% vs. comparable Si fast recovery diodes |
| IR (max) | 100 mA at VR = VRRM, Tj = 125 °C - limits standby power loss in always-on vehicle subsystems |
| Rth(j-c) per diode | 0.4 °C/W - enables thermal design with standard aluminum heatsinks without forced air |
| Insulation rating | 2500 VRMS sine - satisfies reinforced isolation requirements for functional safety in ASIL-B/C systems |
| Tj (max) | +175 °C - permits operation adjacent to IGBT modules in powertrain inverters |
Pinout & Package
ISOTOP package: insulated metal base with four M4 mounting screws, epoxy body rated UL94 V0, 12.0 × 8.0 × 38.0 mm footprint. Designed for direct heatsink mounting with 1.3 N·m torque and 45 mm² contact area per screw.

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-200CT170 | Same 170 V VRRM and 2×100 A rating but non-insulated TO-247 package; Rth(j-c) = 0.55 °C/W per diode | Requires external isolation barrier for chassis-mounting; unsuitable for ASIL-B systems without redesign | Select when cost priority outweighs insulation and thermal performance; verify creepage/clearance compliance separately |
| IXYS DSSK100-017A | 170 V, 2×100 A, insulated SOT-227B package; higher VF (0.72 V typ. at 150 °C); UL1557 certified at 1500 VRMS only | Limited to lower-power auxiliary supplies due to reduced insulation margin and higher conduction loss | Prefer for legacy industrial designs where 1500 VRMS meets safety requirements and thermal budget allows 0.09 V higher VF |
Compared with VS-200CT170 and DSSK100-017A, STPS200170TV1Y delivers superior thermal resistance (0.4 vs. ≥0.55 °C/W), full 2500 VRMS isolation, and lower forward drop-making it the only option qualified for ASIL-C-relevant secondary rectification in next-gen EV power electronics.

FAQ
What is the maximum allowable case temperature for continuous operation?
The device supports continuous operation with case temperature up to 140 °C per diode, as specified in the average forward current derating curve (Figure 1). At this temperature, each diode delivers 100 A average current with δ = 0.5 square wave duty cycle. Exceeding 140 °C requires derating per the published IF(AV) vs. TC curve.
Can STPS200170TV1Y be mounted directly to a conductive vehicle chassis?
Yes-the ISOTOP package provides 2500 VRMS reinforced insulation between the internal dies and the metal base, allowing direct mounting to grounded chassis without additional isolation hardware. Mounting must follow ST's recommended 1.3 ±0.2 N·m torque and use supplied M4 screws to maintain insulation integrity and thermal performance.
How does its avalanche rating compare to standard fast recovery diodes?
STPS200170TV1Y is rated for 7200 W peak avalanche power at 10 µs pulse width and 125 °C junction temperature-significantly exceeding typical Si FRDs (typically <1000 W). This enables reliable operation during short-circuit events or transformer saturation without catastrophic failure, a critical requirement in automotive traction systems.
Is the cathode connection internally commoned between both diodes?
Yes-pinout documentation confirms K1 and K2 are internally shorted to form a single common cathode terminal. This configuration supports dual-anode, single-output rectification essential for center-tapped or interleaved transformer topologies without external wiring.
