Product details
Overview
GBPC2504W from Taiwan Semiconductor is a 25A, 400V glass-passivated quad bridge rectifier in GBPC-W wire-structure package, featuring 1.1V max forward voltage at 12.5A, <5µA reverse leakage at 25°C, and 1.5°C/W junction-to-case thermal resistance - used in high-efficiency AC/DC converters and switching mode power supplies.
For engineers reviewing the GBPC2504W datasheet, GBPC2504W pinout, GBPC2504W application, or GBPC2504W equivalent, key selection criteria include peak repetitive reverse voltage (400V), average forward current (25A), surge capability (400A IFSM), thermal performance (RθJC = 1.5°C/W), and GBPC-W mechanical mounting configuration.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability under transient stress. Its GBPC-W package uses wire-structured terminals and an integrally molded heatsink to achieve low thermal resistance (1.5°C/W) and high surge current handling (400A, 8.3ms half-sine).
The GBPC2504W operates across –55°C to +150°C junction temperature range and meets UL 94V-0 flammability and JESD201 Class 1A whisker requirements. It delivers stable reverse blocking up to 400V VRRM with typical IR <0.2µA and forward conduction characterized at 12.5A DC load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage the device blocks without breakdown |
| IF(AV) | 25 A - continuous average forward current rating at case temperature ≤75°C |
| IFSM | 400 A - non-repetitive peak surge current (8.3ms half-sine) the device withstands |
| VF | ≤1.1 V - maximum forward voltage drop per diode at 12.5A, 25°C, defining conduction loss |
| IR | ≤5 µA - maximum reverse leakage current per diode at rated VR and 25°C |
| RθJC | 1.5 °C/W - thermal resistance from junction to case, critical for heatsink sizing |
| TJ(max) | +150 °C - maximum allowable junction temperature for reliable long-term operation |
Pinout & Package
GBPC2504W uses the GBPC-W package: a molded plastic case with wire-structured terminals, integrally formed heatsink, matte tin-plated leads, and cathode polarity marked on the case. Mounting torque must not exceed 20 in-lbs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Two alternating current input pins - connected to secondary winding of transformer or AC line input |
| + (Anode) | DC Positive Output | Full-wave rectified positive DC output node - connects to bulk capacitor or downstream regulator |
| – (Cathode) | DC Negative Output | Full-wave rectified negative DC output node - common return path for DC load |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable reverse blocking and improved moisture/contamination resistance vs. epoxy-passivated devices |
| Integrally molded heatsink | Reduces thermal resistance to 1.5°C/W, enabling higher power density without external heatsink in moderate-load designs |
| Low IR (<5 µA) | Minimizes standby power loss in offline SMPS and improves efficiency at light loads |
| High IFSM (400 A) | Withstands inrush surges from cold-start capacitors and transformer magnetizing currents without failure |
| UL Recognized (E-326243) | Validates safety compliance for end-equipment certification in commercial and industrial power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC2504 | Same 25A/400V rating and GBPC package, but GBPC (not GBPC-W) with parallel-terminal cathode; RθJC = 1.6°C/W | No wire-structure mounting - requires different PCB footprint and screw-mount orientation | Choose when legacy GBPC layout exists and heatsink interface matches parallel-terminal geometry |
| ON Semiconductor GBPC2504W | Identical electrical specs and GBPC-W mechanical form; minor differences in marking and JEDEC qualification scope | Drop-in compatible in all mechanical and electrical respects per datasheet cross-reference | Preferred for dual-sourcing where Taiwan Semiconductor supply continuity is constrained |
Compared with GBPC2504W, the Vishay GBPC2504 requires PCB layout revision due to terminal orientation, while ON Semiconductor GBPC2504W offers true mechanical and electrical equivalence - making it suitable for second-source qualification without redesign.

FAQ
What is the maximum junction temperature rating for GBPC2504W?
The GBPC2504W has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the Taiwan Semiconductor datasheet M2211. This allows operation in high-ambient environments when paired with appropriate heatsinking. The device also supports storage from –55°C to +150°C. Thermal design must maintain TJ ≤150°C under worst-case load and ambient conditions to ensure reliability of GBPC2504W.
Does GBPC2504W meet RoHS and UL requirements?
Yes, GBPC2504W is RoHS compliant and UL Recognized under File #E-326243. The molding compound meets UL 94V-0 flammability rating, and terminals pass JESD201 Class 1A whisker testing. These certifications are confirmed in the mechanical data and ordering information sections of the official Taiwan Semiconductor datasheet M2211 for GBPC2504W.
What is the forward voltage specification for GBPC2504W at rated current?
Per the electrical specifications table in the Taiwan Semiconductor datasheet, GBPC2504W exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 12.5 A and TJ = 25°C. This value is measured under pulsed conditions (PW = 0.3 ms) and defines conduction loss in the rectifier stage of GBPC2504W-based power supplies.
How does the GBPC-W package differ from GBPC-M or standard GBPC?
The GBPC-W package features wire-structured terminals, whereas GBPC-M has cathode terminals parallel to anode, and standard GBPC uses orthogonal lead geometry. GBPC2504W's wire-structure enables flexible mounting orientation and direct bolt-down heatsink contact. Dimensions, marking layout, and mechanical tolerancing are defined separately in drawing HQ2SD07-GBPCW-056 REV A for GBPC2504W.
What is the peak forward surge current rating for GBPC2504W?
The GBPC2504W is rated for a non-repetitive peak forward surge current (IFSM) of 400 A under an 8.3 ms single half-sine wave condition, as specified in the absolute maximum ratings table. This rating ensures robustness against inrush currents during power-up and fault transients in AC/DC converter applications using GBPC2504W.
