Product details
Overview
GBJ2506 from Diodes Incorporated is a 25A standard recovery bridge rectifier in GBJ package, rated for 600V peak repetitive reverse voltage (VRRM), 1.05V max forward voltage at 12.5A, and 350A peak surge current. It features glass-passivated die construction, 2500VRMS case dielectric strength, and is designed for AC/DC power conversion in industrial power supplies and motor drive front-ends.
For engineers reviewing the GBJ2506 datasheet, GBJ2506 pinout, GBJ2506 application, or GBJ2506 equivalent, key selection criteria include VRRM rating for mains isolation, thermal resistance (1.0°C/W junction-to-case), surge capability (350A IFSM), and through-hole mounting compatibility with #6 screw hardware.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic GBJ molded plastic package. Its standard recovery characteristic (trr not specified, consistent with non-fast-recovery classification) supports line-frequency (50/60Hz) rectification without commutation-related switching losses.
Designed for heatsink-mounted operation, it delivers 25A average output current at TJ = +150°C when mounted on a 250mm × 250mm × 20mm aluminum plate. Reverse leakage remains ≤10µA at 25°C and ≤500µA at 125°C under rated VR.
Key Specifications

| VRRM | 600 V - Ensures safe blocking of 424V RMS AC mains with 1.4× safety margin |
| IF(AV) | 25 A - Sustained DC output current with heatsink at 150°C junction temperature |
| VF Max | 1.05 V @ 12.5A - Directly determines conduction loss (13.1W per half-cycle at full load) |
| IFSM | 350 A - Withstands cold-start inrush into capacitive input filters |
| RθJC | 1.0 °C/W - Enables thermal design using standard aluminum heatsinks without forced air |
| IR Max | 10 µA @ 25°C - Low leakage preserves efficiency in high-impedance hold-up circuits |
| VB | 600 V - Confirmed breakdown voltage at 10µA test current, matching VRRM rating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU8K | Same 600V VRRM, 8A IF(AV), TO-220AC package, lower surge (200A IFSM) | Lower current rating requires parallel use for 25A systems; smaller footprint but higher thermal resistance (2.5°C/W) | Select only if space-constrained and thermal design includes forced air cooling |
| ON Semiconductor GBPC2506 | Identical 600V/25A rating, same GBJ package, but 1.1V VF (vs. 1.05V) and 15µA IR (vs. 10µA) | No functional substitution impact; slightly higher conduction loss and leakage in precision low-power standby | Drop-in replacement where Diodes' supply chain constraints exist; verify thermal margin with 0.05V VF delta |
Compared with GBJ2506, the GBU8K requires derating or paralleling for 25A loads and offers inferior surge immunity, while GBPC2506 matches form/fit/function but trades 50mV higher VF and 5µA higher leakage-acceptable for cost-sensitive, non-standby-critical designs.

FAQ
Is GBJ2506 suitable for high-frequency switching applications?
No. GBJ2506 is a standard recovery bridge rectifier with no specified reverse recovery time (trr), indicating it is optimized for 50/60Hz line-frequency operation. Using it in high-frequency SMPS (>20kHz) would cause excessive switching losses and overheating due to slow carrier recombination.
What is the maximum recommended heatsink thermal resistance for GBJ2506 at 25A?
With RθJC = 1.0°C/W and maximum TJ = 150°C, ambient TA = 50°C, and 13.1W conduction loss (1.05V × 12.5A), the allowable RθSA is ≤3.8°C/W. This assumes ideal mounting on a 250mm × 250mm × 20mm aluminum plate as specified in the datasheet.
Does GBJ2506 meet AEC-Q101 for automotive use?
No. The datasheet explicitly states that automotive qualification (AEC-Q100/101/104/200) requires special change control and PPAP capability, and GBJ2506 is not listed as AEC-Q101 qualified. It is intended for industrial and commercial applications unless specifically requalified.
Can GBJ2506 be mounted directly to a PCB without a heatsink?
No. At 25A average current, junction temperature will exceed 150°C without heatsinking. The datasheet specifies IF(AV) = 25A only with a 250mm × 250mm × 20mm aluminum plate heatsink. For low-duty-cycle or intermittent operation below 5A, board copper area may suffice-but thermal simulation is required.
