Product details

Overview

STPS80H100CWLY from STMicroelectronics is a dual 40 A, 100 V automotive-grade Schottky rectifier in TO-247 long-lead package, featuring 0.62 V typical forward voltage at 125 °C and 40 A per diode, negligible switching losses, and guaranteed operation up to 175 °C junction temperature - deployed as freewheeling diodes in high-frequency LLC and phase-shift DC/DC converters for electric vehicle powertrains.

For engineers reviewing the STPS80H100CWLY datasheet, STPS80H100CWLY pinout, STPS80H100CWLY application, or STPS80H100CWLY equivalent, key selection criteria include dual-diode thermal coupling, avalanche-rated 2900 W peak power, R_th(j-c) = 0.15 °C/W (total), AEC-Q101 qualification, and ECOPACK2 compliance for EV traction and on-board charger systems.

Technical Context

This dual common-cathode Schottky rectifier integrates two independent 40 A diodes sharing a single case, enabling symmetrical current sharing in interleaved topologies. Its low VF and negligible reverse recovery support >100 kHz switching in resonant converters without snubbers.

Thermal design leverages direct conduction cooling via the TO-247LL metal tab (R_th(j-c) = 0.15 °C/W total), while avalanche capability (P_ARM = 2900 W @ 10 µs) provides robustness against inductive turn-off transients in motor drive and DC/DC stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - supports 48–96 V nominal bus systems with 20 % margin for transient overvoltage in EV architectures
I_F(AV)	2 × 40 A - enables 80 A total average output current with dual-diode parallel conduction and shared thermal path
V_F(typ)	0.62 V @ 40 A, 125 °C - reduces conduction loss to ~25 W per diode at full load, critical for thermal budget in sealed power modules
R_th(j-c)	0.15 °C/W (total) - allows 175 °C max junction temperature with ≤25.5 °C case-to-ambient rise at 80 A continuous
I_FSM	550 A @ 10 ms - withstands short-circuit currents during OCP response in 400 V battery-fed inverters
P_ARM	2900 W @ 10 µs - sustains repetitive avalanche energy in phase-shifted full-bridge primary-side clamp circuits

Pinout & Package

TO-247 long-lead (TO-247LL) package with isolated metal tab for mounting; three terminals: two anodes (A1, A2) and one common cathode (K). Mounting torque: 0.8 N·m (max 1.0 N·m); epoxy meets UL94 V0.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	Input terminal for first diode leg; electrically isolated from A2 but thermally coupled through shared case
A2	Anode 2	Input terminal for second diode leg; enables dual-channel freewheeling or interleaved synchronous rectification
K	Common Cathode	Single output node for both diodes; simplifies PCB layout and reduces parasitic inductance in high-dI/dt paths

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain use including 1000-hr HTOL, temperature cycling, and mechanical shock per JESD22
Negligible switching losses	No reverse recovery charge (Q_rr ≈ 0), eliminating switching loss and EMI in >100 kHz LLC resonant converters
High T_j(max)	175 °C rated junction temperature enables compact heatsink design in space-constrained EV onboard chargers
Low leakage current	≤7 mA @ 125 °C, V_R = V_RRM - maintains efficiency in high-temperature battery compartments
ECOPACK2 compliant	Halogen-free, RoHS-compliant packaging meeting EU Directive 2011/65/EU and automotive material restrictions

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS MBR80100CT	Single 80 A device in TO-220AB; higher R_th(j-c) = 0.5 °C/W; no AEC-Q101 qualification	Limited to industrial/non-automotive DC/DC; unsuitable for EV powertrain due to missing PPAP and thermal derating	Select only for cost-sensitive non-automotive 100 V rectification where AEC-Q101 and 175 °C operation are not required
Vishay VS-80SQ040	Dual 40 A, 40 V rating; lower V_RRM; VF = 0.52 V @ 25 °C but degrades to 0.75 V @ 125 °C	Restricted to 24–48 V systems; insufficient for 96 V+ EV bus rails requiring 100 V V_RRM margin	Consider only for low-voltage hybrid systems where 100 V blocking is unnecessary and lower VF at room temperature is prioritized

Compared with MBR80100CT and VS-80SQ040, STPS80H100CWLY uniquely delivers AEC-Q101 compliance, 100 V blocking with 175 °C operation, and dual-diode thermal coupling - making it the sole qualified solution for automotive 48–96 V DC/DC and OBC applications demanding PPAP traceability and lifetime reliability.

FAQ

What is the maximum continuous junction temperature for STPS80H100CWLY?

The absolute maximum operating junction temperature is +175 °C, validated across the full -40 °C to +175 °C storage range and supported by thermal derating curves in DS13815. This rating enables operation in sealed, high-ambient environments such as EV battery enclosures and power module housings without active cooling.

Is STPS80H100CWLY pin-compatible with other TO-247 Schottky rectifiers?

STPS80H100CWLY uses the standard TO-247 long-lead (TO-247LL) mechanical outline with A1–K–A2 pin assignment. While footprint-compatible with generic TO-247LL parts, its dual-anode/common-cathode configuration differs from single-diode or center-tap variants - PCB layout must allocate separate anode pads and a shared cathode pad.

Does STPS80H100CWLY require a heatsink in automotive applications?

Yes - although R_th(j-c) = 0.15 °C/W enables efficient conduction cooling, sustained 80 A operation at 175 °C junction requires a properly mounted heatsink with thermal interface material. The datasheet specifies 0.8 N·m mounting torque and UL94 V0 epoxy compatibility for direct bolt-down to aluminum or copper baseplates.

How does the avalanche rating impact system-level reliability?

The 2900 W peak avalanche power rating (at 10 µs, T_j = 125 °C) ensures controlled energy dissipation during inductive turn-off events, preventing catastrophic failure in phase-shifted full-bridge and LLC converters. This specification is tested per AEC-Q101 stress conditions and directly supports functional safety requirements for ASIL-B power stages.
