Product details
Overview
STBR3012G2Y-TR from STMicroelectronics is an AEC-Q101-qualified automotive high-voltage silicon rectifier diode in D²PAK HV package, rated for 30 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, delivering ultra-low conduction losses (VF typ. 0.95 V at 30 A, 150 °C) and guaranteed VRRM across -40 to +175 °C.
For engineers reviewing the STBR3012G2Y-TR datasheet, STBR3012G2Y-TR pinout, STBR3012G2Y-TR application, or STBR3012G2Y-TR equivalent, key selection criteria include its 5.38 mm minimum creepage distance (anode-to-cathode, with top coating), 0.45 °C/W junction-to-case thermal resistance, and DO-247/D²PAK HV package compatibility for high-reliability EV power systems.
Technical Context
This diode employs planar passivated silicon technology optimized for high-voltage rectification in automotive battery charging systems. Its design ensures stable reverse leakage (<100 µA at 150 °C, VR = VRRM) and low forward voltage drop across wide temperature and current ranges - critical for minimizing conduction losses in unidirectional AC/DC conversion stages.
The D²PAK HV package provides enhanced creepage (5.38 mm min. anode-to-cathode with coating) and thermal performance (Rth(j-c) = 0.45 °C/W), enabling reliable operation under high ambient temperatures and transient surge conditions (IFSM = 300 A, tp = 10 ms sinusoidal).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3012W | DO-247 package, same 30 A / 1200 V rating, but VF = 1.15 V (typ.) at 30 A / 150 °C; Rth(j-c) = 0.55 °C/W | Larger footprint; lower thermal performance limits power density in space-constrained OBCs | Prefer when mechanical mounting requires stud-type package or legacy DO-247 board layout reuse |
| IXYS MBR30120CT | TO-220AB package, dual common-cathode, VF = 1.2 V (typ.) at 30 A / 125 °C; no AEC-Q101 qualification | Not automotive-qualified; lacks creepage certification for 800 V systems | Suitable only for industrial/non-automotive 1200 V rectification where qualification and insulation are not mandated |
Compared with STTH3012W and MBR30120CT, STBR3012G2Y-TR delivers superior thermal performance (0.45 vs. 0.55 °C/W), tighter VF tolerance, and certified AEC-Q101 reliability - making it the only option qualified for ASIL-B OBC front-end use in production EVs.

FAQ
Is STBR3012G2Y-TR pin-compatible with STBR3012-Y?
Yes - both share identical D²PAK HV pinout (A-K1-K2) and mechanical footprint. STBR3012G2Y-TR is the tape-and-reel variant of STBR3012-Y, differing only in packaging format and reel quantity (1000 pcs/reel vs. tube). Electrical and thermal specifications are identical.
What is the recommended PCB copper area for thermal performance?
Per DS11897 Figure 8, a minimum 30 cm² of 35 µm-thick copper on FR4 under the tab reduces Rth(j-a) to ~12 °C/W. For production OBCs, ST recommends ≥40 cm² with internal planes and thermal vias to sustain 30 A continuous current at Tc ≤ 105 °C.
Does this diode require snubber circuits in bridge applications?
Snubbers are not mandatory due to low reverse recovery charge (Qrr not specified, but typical for soft-recovery 1200 V Si diodes is < 1.2 µC). However, ST recommends RC snubbers across each diode in high-dI/dt OBC applications (>50 A/µs) to suppress voltage overshoot during commutation.
Can STBR3012G2Y-TR be used in synchronous rectification topologies?
No - it is a standard PN junction silicon rectifier, not a MOSFET-based synchronous device. It lacks gate control and cannot be actively switched. Its role is strictly unidirectional conduction with inherent reverse recovery; synchronous rectification requires controllable FETs with driver circuitry.
