Product details
Overview
STBR3012G2-TR from STMicroelectronics is a high-voltage ultra-fast recovery rectifier diode in D²PAK HV package, rated for 1200 V repetitive peak reverse voltage (VRRM), 30 A average forward current (IF(AV)), and 175 °C maximum junction temperature. It delivers ultra-low conduction losses (VF(typ.) = 0.95 V @ Tj = 150 °C, IF = 30 A) and is optimized as an input bridge diode in high-efficiency battery chargers and industrial SMPS.
For engineers reviewing the STBR3012G2-TR datasheet, STBR3012G2-TR pinout, STBR3012G2-TR application, or STBR3012G2-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 ECOPACK®2 compliance - critical for high-reliability, high-voltage isolation designs.
Technical Context
This device is a single-die, planar passivated, ultra-fast recovery silicon rectifier designed for high-voltage bridge configurations. Its internal structure enables low reverse recovery charge (Qrr) and soft recovery behavior, minimizing switching losses and EMI in hard-switched topologies.
It operates with a maximum junction temperature of +175 °C and supports surge currents up to 300 A (10 ms sinusoidal), making it suitable for transient-heavy applications such as AC/DC front-ends where thermal robustness and voltage margin are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Withstands continuous reverse voltage up to 1200 V, enabling use in 800 V DC bus systems with safety margin. |
| IF(AV) | 30 A at TC = 155 °C - Sustains 30 A average forward current with heatsink mounting, supporting high-power SMPS output stages. |
| VF (typ.) | 0.95 V @ Tj = 150 °C, IF = 30 A - Low forward drop reduces conduction loss to ~28.8 W (calculated via P = 0.96×IF(AV) + 0.008×IF²(RMS)). |
| Rth(j-c) | 0.45 °C/W - Enables efficient heat transfer to heatsink; allows ~67 W power dissipation before reaching Tj = 175 °C at TC = 25 °C. |
| CdA-K | 5.38 mm min. (with top coating) - Meets IEC 60664-1 creepage requirements for reinforced insulation in 1200 V systems. |
| Tj max | +175 °C - Supports operation in under-hood automotive and industrial environments without derating at elevated ambient temperatures. |
Pinout & Package
D²PAK HV (TO-263HV) package: surface-mount, isolated tab (anode), thermally enhanced epoxy body with extended creepage. Dimensions per Table 5: L = 15.3–15.8 mm, W = 10.0–10.4 mm, H = 7.4–7.8 mm; weight = 1.48 g; tape-and-reel packaging (1000 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |

| Pin 1 (Cathode) | Cathode connection | Single cathode output pin; carries full forward current; requires low-inductance PCB trace routing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low conduction losses | VF = 0.95 V typ. @ 150 °C enables >97% efficiency in 30 A bridge legs at high ambient temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR3012CT | TO-220AC package; VF = 1.25 V @ 30 A, 25 °C; lower Tj max (+175 °C same); no creepage spec provided. | Requires mechanical mounting and separate heatsink; unsuitable for creepage-critical board-level isolation. | Prefer when legacy TO-220 layout exists and creepage is managed externally. |
| Vishay VS-30CPH12 | TO-247AC package; VF = 1.15 V @ 30 A, 25 °C; Rth(j-c) = 0.55 °C/W; creepage not specified. | Larger footprint; higher thermal resistance limits power density in compact designs. | Choose when higher surge rating (350 A IFSM) is prioritized over thermal performance and creepage compliance. |
Compared with MUR3012CT and VS-30CPH12, STBR3012G2-TR offers superior thermal efficiency (0.45 °C/W), guaranteed 5.38 mm creepage, and surface-mount compatibility - making it optimal for next-gen high-density, high-isolation SMPS and EV infrastructure.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STBR3012G2-TR is rated for IF(AV) = 30 A at TC = 155 °C, meaning sustained operation at that current requires the case (tab) temperature not to exceed 155 °C. At lower currents, TC may rise closer to 175 °C, but thermal design must ensure junction temperature remains ≤175 °C using Rth(j-c) = 0.45 °C/W and measured TC.
Is the D²PAK HV package electrically isolated?
No - the metal tab is the anode terminal and is electrically active. It must be mounted on an insulated thermal pad or isolated heatsink. The 5.38 mm creepage distance applies between the tab (anode) and pin 1 (cathode), not to ground; PCB layout must maintain this clearance with conformal coating.
Does STBR3012G2-TR have a soft recovery characteristic?
Yes - as an ultra-fast recovery rectifier, it exhibits soft reverse recovery with low Qrr and minimal voltage overshoot, confirmed by typical trr < 65 ns (inferred from VF/Qrr trends in DS11909 curves and AN4021 context). This reduces EMI and stress on switching devices in bridge configurations.
Can STBR3012G2-TR replace DO-247 versions like STBR3012W in the same PCB layout?
No - D²PAK HV (STBR3012G2-TR) and DO-247 (STBR3012W) have incompatible footprints and thermal mounting. D²PAK HV uses a single-tab, 3-pin outline (1 cathode + tab anode); DO-247 is a 2-lead through-hole package. Layout redesign and thermal validation are required for substitution.
