Product details
Overview
GBPC2506W from Diodes Incorporated is a 25A glass passivated single-phase bridge rectifier with 600V peak repetitive reverse voltage (VRRM), 1.1V forward voltage per element at 12.5A, 300A non-repetitive surge rating, and metal-base heatsink for thermal management - used in AC/DC power supplies for industrial motor drives.
For engineers reviewing the GBPC2506W datasheet, GBPC2506W pinout, GBPC2506W application, or GBPC2506W equivalent, key selection criteria include VRRM derating for capacitive loads, case temperature–dependent current derating, thermal resistance (1.3°C/W junction-to-case), and UL recognition (E94661) for safety-critical power conversion.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions to suppress surface leakage and enhance reliability under humid or high-voltage stress conditions. Its internal metal base provides direct thermal conduction to an external heatsink, enabling sustained 25A average output at TC = 60°C when mounted on a 220 × 220 × 50 mm aluminum plate.
The GBPC2506W operates with fixed polarity: two AC input terminals, one positive DC output (+), and one negative DC output (–). It exhibits 300 pF typical total capacitance per element at 1 MHz and 4V reverse bias, limiting high-frequency noise coupling in switching power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum peak reverse voltage each diode withstands without breakdown; defines maximum AC input RMS voltage (420 V) before derating. |
| IO @ TC=60°C | 25 A - Average DC output current sustainable with case temperature held at 60°C using external heatsink. |
| VFM @ IF=12.5A | 1.1 V - Forward voltage drop per diode leg at half-rated current; determines conduction loss (2.2 V total bridge drop at 12.5A). |
| IFSM (8.3ms) | 300 A - Peak surge current tolerance for one half-sine cycle; supports inrush current handling in transformer-fed supplies. |
| RθJC | 1.3 °C/W - Junction-to-case thermal resistance with heatsink mounting; enables thermal design using measured case temperature. |
| IR @ 25°C | 5.0 µA - Reverse leakage per diode at rated DC blocking voltage; low leakage preserves efficiency in high-impedance hold-up circuits. |
| Isolation Voltage | 1500 V - Dielectric strength between case and terminals; satisfies reinforced insulation requirements for Class I equipment. |
Pinout & Package
Package: GBPC-W - Molded plastic case with internally mounted metal heatsink base, wire leads (no Faston terminals), UL 94V-0 flammability rating, and #10 screw mounting hole (5.08–5.59 mm diameter).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 / AC2 | AC Input Terminals | Two symmetrical inputs accepting single-phase AC; interchangeable; define bridge input node pair. |
| (+) | Positive DC Output | Anode of common-cathode pair; connects to bulk capacitor positive rail or downstream regulator input. |
| (–) | Negative DC Output | Cathode of common-anode pair; serves as system ground reference or return path for DC load current. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Reduces surface leakage current and improves long-term stability under humidity and high-voltage bias. |
| Metal base integrated into package | Enables direct mechanical and thermal attachment to heatsink without additional thermal interface material. |
| UL Recognized Component (E94661) | Validates isolation, flammability, and construction compliance for end-equipment safety certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBJ2506 | Same VRRM (600 V), IO (25 A), and RθJC (1.3°C/W); uses GBJ package with insulated plastic base instead of metal base. | No direct case-to-heatsink thermal path; requires thermal pad or paste; lower mounting torque tolerance (5.5 in-lb vs. 8.0 in-lb). | Select when board-level thermal management allows insulated mounting and space constraints favor smaller footprint. |
| KBPC2506 | Same electrical specs but epoxy-molded package (no metal base); higher RθJC (1.8°C/W); no UL recognition. | Limited to lower ambient temperatures or forced-air cooling; not acceptable for UL-certified end equipment. | Select only for cost-sensitive, non-safety-certified consumer applications with adequate airflow. |
Compared with GBJ2506 and KBPC2506, GBPC2506W offers superior thermal performance via direct metal-base heatsinking and certified safety isolation - critical for industrial and medical power supplies where thermal margin and regulatory compliance are non-negotiable.

FAQ
What is the maximum allowable mounting torque for GBPC2506W?
The maximum mounting torque for GBPC2506W is 8.0 inch-pounds when securing the #10 screw through its integrated metal base. Exceeding this value risks cracking the molded plastic case or deforming the internal heatsink interface, compromising thermal performance and mechanical integrity.
Can GBPC2506W be used with capacitive loads without derating?
No - the datasheet explicitly requires a 20% current derating for capacitive loads due to elevated peak charging currents that increase thermal stress beyond resistive or inductive load conditions. At full 25 A rating, capacitive operation must be limited to 20 A average output current to maintain safe junction temperature.
Is GBPC2506W compliant with RoHS and REACH regulations?
Yes - GBPC2506W carries lead-free finish and is RoHS compliant per EU Directive 2002/95/EC, with documented exemptions for high-temperature solder and glass components (Annex Notes 5 and 7). It also meets REACH SVHC thresholds, with full declaration available in Diodes' material compliance reports.
Does GBPC2506W require external snubber circuitry?
Not inherently - its 300 pF typical junction capacitance and glass-passivated structure provide inherent suppression of voltage transients. However, snubbers may still be needed in high-dI/dt applications (e.g., SCR-controlled phase-angle dimming) to limit dv/dt-induced false triggering in downstream thyristor circuits.
