Product details
Overview
STBR6012WY from STMicroelectronics is an AEC-Q101-qualified ultra-low-loss automotive high-voltage silicon rectifier diode in DO-247 package, rated for 60 A average forward current, 1200 V repetitive peak reverse voltage, and 175 °C maximum junction temperature. It serves as a robust input bridge diode in on-board chargers (OBC), delivering low conduction loss (VF typ. 0.95 V at 150 °C) and stable reverse blocking across -40 to +175 °C.
For engineers reviewing the STBR6012WY datasheet, STBR6012WY pinout, STBR6012WY application, or STBR6012WY equivalent, key selection criteria include its guaranteed VRRM over full automotive temperature range, ultra-low reverse leakage (<250 µA at 150 °C), thermal resistance (Rth(j-c) = 0.45 °C/W), surge capability (500 A IFSM), and ECOPACK®2 compliance for sustainable sourcing.
Technical Context
This device is a single-die, planar passivated silicon power rectifier optimized for high-efficiency AC/DC conversion in harsh automotive environments. Its design ensures stable VF drift with temperature, minimal IR increase at elevated Tj, and repeatable surge performance under sinusoidal 10 ms pulses up to 500 A.
The DO-247 package enables direct case-to-heatsink conduction cooling with 0.8 N·m recommended mounting torque. Thermal impedance modeling supports accurate transient power loss estimation using the provided conduction loss equation: P = 0.96 × IF(AV) + 0.004 × IF²(RMS).
Key Specifications

| VF (typ.) | 0.95 V @ 60 A, 150 °C - Enables low conduction loss in high-power OBC front-end rectification |
| Rth(j-c) | 0.45 °C/W - Supports efficient heat transfer to heatsink; enables compact thermal design in space-constrained OBC modules |
| IFSM | 500 A @ 10 ms sine - Withstands inrush surges during AC line connection without degradation |
| IR (max) | 250 µA @ 1200 V, 150 °C - Ensures minimal standby power loss and system efficiency retention at high ambient temperatures |
| Tj max | +175 °C - Meets under-hood automotive reliability requirements and enables derating flexibility |
Pinout & Package
STBR6012WY is a two-terminal discrete diode in DO-247 package: anode and cathode are accessed via the metal case (cathode) and central lead (anode), per standard DO-247 configuration. The package uses epoxy meeting UL94 V0, with case cooling by conduction and 0.8 N·m recommended mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead) | Forward current entry point | Connected to AC input phase; must withstand 500 A surge and sustain 60 A continuous conduction |
| Cathode (case) | Forward current exit / thermal path | Electrically and thermally tied to heatsink; provides primary thermal dissipation path (Rth(j-c) = 0.45 °C/W) |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage automotive rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MBR60120CT | TO-247 package, 1200 V VRRM, VF = 1.15 V @ 60 A, 25 °C; no AEC-Q101 qualification | Rated for industrial, not automotive-grade reliability or PPAP support | Use only where AEC-Q101 and PPAP are not required; higher VF increases conduction loss by ~21% at 150 °C |
| Vishay VS-60CPH12 | TO-247AC package, 1200 V VRRM, VF = 1.08 V @ 60 A, 25 °C; AEC-Q101 qualified but no ECOPACK®2 claim | Lacks halogen-free certification and full automotive traceability documentation | Acceptable for automotive use where ECOPACK®2 compliance is not mandated by Tier-1 procurement policy |
Compared with MBR60120CT and VS-60CPH12, STBR6012WY uniquely combines AEC-Q101 qualification, ECOPACK®2 compliance, and the lowest VF (0.95 V) at 150 °C - making it the only option fully aligned with OEM OBC BOM requirements for next-generation 800 V platforms.

FAQ
What is the mounting torque specification for STBR6012WY?
The DO-247 package specifies a recommended mounting torque of 0.8 N·m and a maximum torque of 1.0 N·m. Exceeding 1.0 N·m risks mechanical damage to the case seal or internal bond wires. Proper torque ensures optimal thermal contact between the cathode case and heatsink while maintaining hermetic integrity under thermal cycling.
Does STBR6012WY support paralleling for higher current?
Yes - STBR6012WY's positive VF temperature coefficient enables natural current sharing when paralleled. However, layout symmetry, matched thermal paths, and individual gate resistors (if used with active control) are required. Derating to 50–55 A per device is advised for sustained operation above 135 °C case temperature.
Is STBR6012WY pin-compatible with STBR6012-Y?
Yes - STBR6012WY and STBR6012-Y share identical DO-247 mechanical footprint, terminal configuration, and electrical specifications. The "WY" suffix denotes a specific wafer lot and assembly flow compliant with additional traceability requirements for certain Tier-1 programs; functionally and physically interchangeable.
How is reverse recovery handled in STBR6012WY?
STBR6012WY is a standard silicon PN junction rectifier with no soft-recovery or controlled Qrr optimization. Its reverse recovery is not specified in the datasheet; it is intended for line-frequency (50/60 Hz) and low-frequency (<1 kHz) rectification only. For high-frequency switching, a fast-recovery or SiC Schottky alternative is required.
