Product details
Overview
GBPC2502 from Taiwan Semiconductor is a 25A, 200V standard single-phase bridge rectifier in GBPC package with quad diode configuration, glass-passivated junctions, and integrally molded heatsink for low thermal resistance (1.5°C/W); used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC2502 datasheet, GBPC2502 pinout, GBPC2502 application, or GBPC2502 equivalent, key selection factors include peak reverse voltage (200V), average forward current (25A), surge capability (400A), thermal resistance (1.5°C/W), and RoHS-compliant matte tin-plated leads.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with common cathode and anode terminals. Its glass-passivated junction ensures stable reverse leakage (<5µA at rated VR) and high reliability under thermal cycling.
The GBPC2502 uses a thermally optimized GBPC package with integral heatsink, enabling direct mounting to external heat sinks. It supports 8.3ms non-repetitive surge currents up to 400A and operates across -55°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the device blocks without breakdown |
| IF(AV) | 25 A - Continuous average forward current per device at 150°C case temperature |
| IFSM | 400 A - Peak non-repetitive forward surge current (8.3ms half-sine wave) |
| RθJC | 1.5 °C/W - Thermal resistance from junction to case, critical for heatsink sizing |
| VF @ IF | 1.1 V max @ 12.5A - Forward voltage drop per diode, determines conduction loss |
| IR @ VRRM | 5 µA max @ 25°C - Reverse leakage current per diode, affects standby power loss |
| TJ max | +150°C - Maximum allowable junction temperature for reliable long-term operation |
Pinout & Package
GBPC2502 is housed in the standard GBPC through-hole package with integral heatsink, 4-pin configuration (AC1, AC2, +, –), and cathode indicator marking. Dimensions: 29.0 × 19.1 × 17.6 mm (L×W×H), weight ≈16.95g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC input terminal 1 | One of two alternating current inputs to full-wave bridge; symmetrical with AC2 |
| AC2 | AC input terminal 2 | Second AC input; completes bridge input path with AC1 |
| + | DC output anode | Positive DC output node; connects to load/anode-side filtering |
| – | DC output cathode | Negative DC output node; marked with cathode symbol; reference ground return |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables <5µA reverse leakage and improved humidity/contamination resistance vs. epoxy-passivated alternatives |
| Integrally molded heatsink | Reduces RθJC to 1.5°C/W, allowing higher continuous current without external heatsink at moderate ambient |
| UL Recognized (E-326243) | Validates safety compliance for end-equipment certification in commercial/industrial power supplies |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and eliminates whisker growth risk (JESD 201 Class 1A) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC2502-E4/51 | Identical electrical specs (25A, 200V), same GBPC package, but lead finish is SnPb (non-RoHS) | Not suitable for RoHS-compliant production; requires exemption documentation | Select only if legacy SnPb assembly is mandated and compliance waivers are approved |
| ON Semiconductor GBPC2502 | Same ratings and package; datasheet specifies slightly higher typical VF (1.15V) and lower IFSM (375A) | Marginally reduced surge robustness; may require derating in high-line transient environments | Acceptable for cost-sensitive designs where 25A/200V performance is primary and surge margin is secondary |
Compared with GBPC2502, the Vishay part offers identical performance but lacks RoHS compliance, while the ON Semiconductor variant trades minor surge margin for broader second-source availability-both require verification of thermal interface and mounting torque (≤20 in-lbs) in final layout.

FAQ
What is the maximum junction temperature rating for GBPC2502?
The GBPC2502 has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version M2211). This rating allows sustained operation in high-ambient environments when paired with appropriate heatsinking. Exceeding this limit risks irreversible degradation of the glass-passivated junction. The GBPC2502 must be mounted with ≤20 in-lbs torque to maintain thermal contact integrity.
Does GBPC2502 meet RoHS requirements?
Yes, GBPC2502 is RoHS compliant, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version M2211). Its matte tin-plated leads conform to J-STD-002 solderability standards and pass JESD 201 Class 1A whisker testing. The molding compound meets UL 94V-0 flammability requirements, supporting environmentally regulated end-product certifications.
What is the forward voltage drop specification for GBPC2502?
The GBPC2502 has a maximum forward voltage (VF) of 1.1 V per diode at IF = 12.5 A and TJ = 25°C, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value reflects worst-case conduction loss under pulsed test conditions (PW = 0.3 ms). At higher temperatures or continuous DC, VF decreases slightly due to negative temperature coefficient.
How is polarity marked on the GBPC2502 package?
The GBPC2502 uses a standardized cathode indicator: a white band or molded cathode symbol ("–") adjacent to the cathode terminal (– pin) on the package body, located near the chamfered corner. The marking diagram in the datasheet (Page 4) confirms this orientation, with "AC", "+", and "–" labels aligned to respective pins. Polarity must be verified before PCB layout to prevent reverse connection.
What is the thermal resistance from junction to case for GBPC2502?
The junction-to-case thermal resistance (RθJC) of GBPC2502 is 1.5°C/W, as specified in the Thermal Performance table of the Taiwan Semiconductor datasheet (Version M2211). This low value results from the integrally molded heatsink structure and enables efficient heat transfer to external heatsinks or chassis mounts. Proper mounting pressure and thermal interface material are essential to achieve this rating in practice.
