Product details
Overview
STBR3012L2Y-TR from STMicroelectronics is an AEC-Q101-qualified automotive high-voltage bridge rectifier diode in HU3PAK package, rated for 30 A average forward current, 1200 V repetitive peak reverse voltage, and 175 °C maximum junction temperature. Its ultra-low conduction losses (VF = 0.95 V typ. at 30 A, 150 °C) and low reverse leakage (<100 µA at 150 °C, VR = VRRM) make it suitable for on-board charger input bridges.
For engineers reviewing the STBR3012L2Y-TR datasheet, STBR3012L2Y-TR pinout, STBR3012L2Y-TR application, or STBR3012L2Y-TR equivalent, key selection criteria include thermal resistance (Rth(j-c) = 0.45 °C/W), surge capability (IFSM = 300 A, 10 ms), and ECOPACK2 compliance for automotive power conversion systems.
Technical Context
This device is a single-die, dual-anode common-cathode configuration optimized for full-wave bridge rectification in high-reliability automotive charging systems. It delivers stable reverse blocking up to 1200 V across -40 to +175 °C and maintains low VF drift with temperature due to its silicon design and optimized metallization.
The HU3PAK package enables direct copper-clad PCB mounting with low thermal impedance and supports high-current routing via three exposed source terminals (pins A, A, A) and two cathode terminals (pins K, K). Its rugged construction ensures mechanical robustness under thermal cycling and vibration stress typical of EV on-board chargers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 30 A - continuous DC output current capability at TC = 150 °C, enabling compact OBC designs without forced air cooling |
| VRRM | 1200 V - guaranteed reverse blocking voltage over full automotive temperature range (-40 to +175 °C) |
| VF (typ.) | 0.95 V @ 30 A, 150 °C - low conduction loss reduces power dissipation and improves system efficiency |
| Rth(j-c) | 0.45 °C/W - enables efficient heat transfer to heatsink or PCB copper, supporting >45 W power handling |
| IFSM | 300 A @ 10 ms sinusoidal - withstands inrush surges during AC line connection in OBC startup |
| Tj max | +175 °C - allows operation in high-ambient under-hood environments without derating |
| IR (max) | 100 µA @ 150 °C, VR = VRRM - minimal leakage preserves efficiency in high-voltage standby modes |
Pinout & Package
HU3PAK is a surface-mount, thermally enhanced power package with integrated copper clip and exposed metal pads for low-inductance, high-current connections. It features a dual-anode/common-cathode internal configuration, with three anode terminals and two cathode terminals arranged for symmetrical current sharing in bridge layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A (Pin 1, 2, 3) | Anode | Three parallel anode connections reduce series resistance and improve current sharing in bridge configurations |
| K (Pin 4, 5) | Cathode | Dual cathode terminals support balanced current distribution and lower thermal gradient across die |
| NC (Pin 6, 7) | No Connect | Unused internal terminals - electrically isolated and not bonded; must remain unconnected |

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 MBR30120CT | TO-220AC package, higher Rth(j-c) = 1.2 °C/W, VF = 1.1 V @ 30 A, 25 °C | Lacks AEC-Q101 qualification; intended for industrial, not automotive use | Select only for non-automotive, cost-sensitive designs where thermal margin permits larger heatsink |
| Vishay VS-30CPH12-M3 | TO-247AC package, VF = 0.98 V @ 30 A, 150 °C, but Tj max = +175 °C not guaranteed over full temp range | Not PPAP-capable; limited documentation for automotive process validation | Consider only if HU3PAK footprint compatibility is not required and PPAP submission is unnecessary |
Compared with MBR30120CT and VS-30CPH12-M3, STBR3012L2Y-TR uniquely combines AEC-Q101 qualification, PPAP readiness, and HU3PAK's low thermal resistance-making it the only option qualified for production automotive OBCs requiring zero-defect reliability and thermal density.

FAQ
Is STBR3012L2Y-TR suitable for synchronous rectification?
No. STBR3012L2Y-TR is a standard PN junction rectifier diode-not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. Its design targets passive rectification where simplicity, ruggedness, and high-voltage blocking are prioritized over ultra-low VF at light loads.
What is the recommended PCB footprint for HU3PAK mounting?
The official recommended footprint is defined in Figure 9 of DS14601: 19.00 mm × 14.70 mm pad area with six 1.27 mm pitch anode/cathode pads and seven 0.90 mm pitch thermal vias. Thermal relief and copper pour under the package backside are mandatory to achieve the specified 0.45 °C/W Rth(j-c).
Does STBR3012L2Y-TR support paralleling for higher current?
Yes-its dual-anode/common-cathode structure and matched VF characteristics across terminals enable current sharing when multiple devices are paralleled. However, external balancing resistors or matched trace lengths are required to ensure equal dynamic current division during transients.
Can this diode replace older STTH3012TV in existing designs?
Yes, with caveats: STBR3012L2Y-TR offers identical voltage/current ratings and improved thermal resistance (0.45 vs. 0.65 °C/W), but uses HU3PAK instead of TO-247. Mechanical redesign of the PCB footprint and thermal interface is required; electrical behavior is functionally equivalent and validated for automotive OBC use cases.
