Product details
Overview
GBPC2506M from Taiwan Semiconductor is a 25A, 600V standard bridge rectifier in GBPC-M package with quad configuration, glass-passivated junctions, and integral heatsink for low thermal resistance (1.5°C/W); used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC2506M datasheet, GBPC2506M pinout, GBPC2506M application, or GBPC2506M equivalent, key selection factors include peak reverse voltage (600V), 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 diodes in a single-phase full-wave bridge configuration with cathode terminal parallel to anode (GBPC-M variant), enabling direct AC input rectification into pulsating DC output. Its glass-passivated junction ensures stable reverse leakage (<5µA at rated VR) and high reliability under thermal cycling.
The molded GBPC-M package features a heatsink structure optimized for mechanical mounting and thermal conduction, supporting continuous operation up to 150°C junction temperature while maintaining UL 94V-0 flammability rating and JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the bridge withstands without breakdown |
| IF(AV) | 25 A - average forward current per diode path under specified thermal conditions |
| IFSM | 400 A - non-repetitive peak surge current for 8.3ms half-sine, critical for inrush handling |
| RθJC | 1.5 °C/W - junction-to-case thermal resistance, determines heatsink sizing requirement |
| IR | <5 µA - maximum reverse leakage per diode at rated VR and 25°C, impacts standby loss |
| TJ(max) | +150 °C - maximum allowable junction temperature, defines upper thermal operating limit |
Pinout & Package
GBPC2506M uses the GBPC-M package: a molded, heatsink-integrated quad bridge with terminals arranged so the cathode lead runs parallel to the anode lead. Dimensions are 29.0 × 17.6 × 24.6 mm (L×W×H), with four mounting holes (Ø5.59 mm) and cathode polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Two alternating current inputs accepting full-wave AC source; electrically symmetrical |
| + | DC Output Anode | Positive DC output node; connects to bulk capacitor positive rail in SMPS front-end |
| – | DC Output Cathode | Negative DC output node; referenced to system ground or return path in isolated converters |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables <5 µA reverse leakage and long-term stability under humidity/temperature stress |
| Integral heatsink structure | Reduces RθJC to 1.5°C/W, allowing 25A operation with minimal external heatsinking |
| 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 tin whisker risk (JESD201 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 |
|---|---|---|---|
| GBPC2506 | Same electrical specs but GBPC (non-M) package: cathode perpendicular to anode; higher RθJC (1.8°C/W) | Requires larger heatsink or forced air for same 25A load; less suitable for space-constrained layouts | Select GBPC2506M when board space is limited and thermal performance must be maximized with minimal heatsink area |
| GBU25J | 25A/600V GBU package; lower IFSM (350A vs. 400A); RθJC = 2.0°C/W; no integral heatsink | Needs external heatsink mounting; not UL-recognized; lacks JESD201 whisker testing | Choose GBPC2506M for certified, high-surge, low-maintenance designs where reliability and safety approvals are mandatory |

FAQ
What is the peak reverse voltage rating of GBPC2506M?
The GBPC2506M has a repetitive peak reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2211). It defines the maximum instantaneous reverse voltage the device can block across its AC terminals without breakdown, making GBPC2506M suitable for 230VAC mains-derived applications with safety margin.
Does GBPC2506M have UL recognition?
Yes, GBPC2506M is UL Recognized under File # E-326243. This certification applies to the entire GBPC15/25/35 series, including the GBPC-M variant. UL recognition confirms compliance with UL 60747-4 for semiconductor devices and supports end-product safety approvals in North America and other regions accepting UL standards.
What is the thermal resistance from junction to case for GBPC2506M?
The junction-to-case thermal resistance (RθJC) of GBPC2506M is 1.5°C/W, as specified in the Thermal Performance section of the Taiwan Semiconductor datasheet. This low value results from the integral heatsink structure in the GBPC-M package and directly determines the required heatsink size for maintaining TJ ≤ 150°C at 25A continuous load.
How is polarity marked on the GBPC2506M case?
GBPC2506M uses a cathode indicator: a channeled corner and "+" marking adjacent to the positive DC output terminal. The cathode (–) terminal is also marked with a "–" symbol on the molded case, consistent with the GBPC-M outline drawing (HQ2SD07-GBPCM-055 REV A). Polarity is further confirmed by the marking code "YWWF" format on the body, where orientation follows standard bridge rectifier conventions.
Is GBPC2506M RoHS compliant and lead-free?
Yes, GBPC2506M is RoHS compliant and lead-free. The datasheet explicitly states "RoHS Compliant" in the FEATURES section and specifies matte tin-plated leads meeting J-STD-002 solderability requirements. All materials-including molding compound (UL 94V-0 rated) and internal metallization-are fully compliant with Directive 2011/65/EU and its amendments.
