Product details
Overview
GBPC2506W from Taiwan Semiconductor is a 25A, 600V standard bridge rectifier in GBPC-W wire-structure package, featuring glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and <5µA reverse leakage at 25°C. It delivers high surge current capability (400A IFSM) for AC/DC conversion in industrial power supplies.
For engineers reviewing the GBPC2506W datasheet, GBPC2506W pinout, GBPC2506W application, or GBPC2506W equivalent, key selection criteria include rated forward current (25A), peak reverse voltage (600V), thermal performance (RθJC = 1.5°C/W), and GBPC-W mechanical configuration with integrated heatsink.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single molded package with wire-structure (GBPC-W) terminals optimized for heatsink mounting. Its glass-passivated junction ensures stable reverse characteristics and low IR (<5 µA) across temperature.
The device operates over -55°C to +150°C junction range and supports 8.3ms half-sine surge currents up to 400A. Thermal design is enabled by direct case-to-heatsink conduction via its integrally molded heatsink and low RθJC of 1.5°C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 25 A continuous - supports medium-power SMPS output stages without forced air cooling |
| Peak Reverse Voltage (VRRM) | 600 V - compatible with 400VAC input lines after rectification with safety margin |
| Surge Current (IFSM) | 400 A (8.3ms) - withstands inrush during cold-start of industrial AC-DC converters |
| Junction-to-Case Thermal Resistance | 1.5 °C/W - enables efficient heat transfer to external heatsink, limiting ΔT to 37.5°C at full load |
| Reverse Leakage (IR) | <5 µA @ 25°C - minimizes standby power loss in offline power supplies |
| Max Junction Temperature | +150 °C - allows operation in enclosed, high-ambient industrial enclosures |
Pinout & Package
GBPC2506W uses the GBPC-W package: a quad-bridge rectifier in an integrally molded plastic case with wire-structure terminals (not PCB pins), designed for bolt-down heatsink mounting. Cathode and anode terminals are accessible on opposite sides of the base for low-inductance AC/DC routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Two independent AC inputs accepting full-wave bridge configuration; symmetric layout simplifies transformer secondary routing |
| + (Anode) | DC Positive Output | Common anode node delivering rectified positive DC; marked with cathode indicator symbol on case |
| – (Cathode) | DC Negative Output | Common cathode node - electrically tied to heatsink mounting surface; requires insulated mounting if heatsink is grounded |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable IR <5 µA and long-term reliability under humid or thermally cycled conditions |
| Integrally molded heatsink | Reduces thermal resistance to 1.5°C/W, eliminating need for separate heatsink hardware in many 25A applications |
| UL Recognized (E-326243) | Validates flammability (UL 94V-0), terminal solderability (J-STD-002), and whisker resistance (JESD201 Class 1A) |
| Wire-structure (GBPC-W) terminals | Supports high-torque (20 in-lbs max) mechanical attachment to heatsinks while maintaining low contact resistance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC2506 | Same 25A/600V rating, GBPC package but with terminal-cathode parallel to anode (GBPC-M style); RθJC = 1.6°C/W | Requires different heatsink hole pattern; slightly higher thermal resistance limits high-ambient use | Prefer when existing PCB layout uses GBPC-M footprint and no redesign is possible |
| ON Semiconductor GBPC2506W | Identical GBPC-W mechanical form, same 25A/600V specs, but IR spec is ≤10 µA (vs. ≤5 µA for TSC) | Acceptable where reverse leakage margin is relaxed; identical mounting and thermal interface | Choose when dual-sourcing is required and ≤10 µA IR meets system standby loss budget |
Compared with GBPC2506W, Vishay GBPC2506 offers mechanical compatibility with GBPC-M layouts but trades 0.1°C/W higher thermal resistance, while ON Semiconductor GBPC2506W matches the wire-structure form factor exactly but specifies looser reverse leakage-both require validation against thermal and leakage thresholds in final design.

FAQ
What is the maximum junction temperature rating for GBPC2506W?
The GBPC2506W has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial cabinets or near heat-generating components. Derating curves confirm usable forward current down to ~12A at 125°C case temperature. Always maintain thermal interface integrity between GBPC2506W's heatsink surface and mounted heatsink to achieve this rating.
Does GBPC2506W have UL recognition?
Yes, GBPC2506W is UL Recognized under File #E-326243. This covers compliance with UL 94V-0 flammability, J-STD-002 solderability of matte tin-plated leads, and JESD201 Class 1A whisker resistance. UL recognition applies specifically to the GBPC-W package variant and supports safety certification of end equipment using GBPC2506W in primary-side rectification circuits.
What is the forward voltage drop of GBPC2506W at rated current?
At 25°C junction temperature and 12.5A forward current per diode (half-bridge leg), GBPC2506W exhibits a typical forward voltage drop of ≤1.1V per diode, resulting in ~2.2V total bridge drop at full 25A DC output. This value is measured under pulsed conditions (PW = 0.3ms) and remains stable due to glass-passivated junction technology. Actual drop increases with temperature and current, as shown in Fig.4 of the datasheet.
How is polarity marked on the GBPC2506W case?
GBPC2506W uses a cathode indicator: a molded "+" symbol adjacent to the common anode terminal and a channeled corner marking the cathode side. The marking diagram on page 5 confirms "CATHODE INDICATOR" on the heatsink side opposite the AC terminals. Polarity must be verified visually before mounting, as incorrect orientation causes immediate failure under AC input.
What is the mounting torque specification for GBPC2506W?
The recommended maximum mounting torque for GBPC2506W is 20 in-lbs (2.26 N·m). This applies to the screw securing the device to its heatsink through the central mounting hole. Exceeding this torque risks cracking the molded GBPC-W case or deforming internal wire bonds. Use a calibrated torque driver and flat, clean heatsink surfaces to ensure uniform pressure and optimal thermal contact for the specified RθJC of 1.5°C/W.
