Product details
Overview
GBPC2506 from Taiwan Semiconductor is a 25A, 600V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, 1.5°C/W junction-to-case thermal resistance, and <5μA reverse leakage at rated voltage - used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC2506 datasheet, GBPC2506 pinout, GBPC2506 application, or GBPC2506 equivalent, key selection factors include peak repetitive reverse voltage (600V), average forward current (25A), surge capability (400A @ 8.3ms), thermal performance, and UL recognition for safety-critical power conversion designs.
Technical Context
The GBPC2506 integrates four silicon diodes in a single-phase full-wave bridge configuration with glass-passivated junctions for enhanced reliability and low IR. Its molded heatsink structure enables direct PCB mounting and efficient heat transfer to external heatsinks.
It operates across -55°C to +150°C junction temperature range and supports RMS input voltages up to 420V. The device meets UL 94V-0 flammability rating and JESD201 Class 1A whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum non-repetitive reverse voltage the bridge withstands without breakdown |
| IF(AV) | 25 A - continuous average forward current per bridge, derated above 75°C case temperature |
| IFSM | 400 A - peak non-repetitive surge current for 8.3 ms half-sine, critical for inrush handling |
| RθJC | 1.5 °C/W - thermal resistance from junction to case, enabling high-power dissipation with heatsink attachment |
| VF (per diode) | 1.1 V max @ 12.5A, 25°C - forward voltage drop determining conduction loss and thermal load |
| IR | <5 µA @ rated VR - low reverse leakage preserves efficiency in high-impedance hold-up stages |

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 | Identical electrical specs (25A/600V), same GBPC package, UL recognized, but uses different molding compound formulation | No functional difference; validated in same SMPS reference designs | Select for dual-sourcing continuity where Vishay supply chain preference applies |
| ON Semiconductor GBPC2506 | Same ratings and package; junction-to-case thermal resistance 1.6°C/W (vs. TSC's 1.5°C/W), IR spec ≤10µA (vs. ≤5µA) | Slightly higher conduction loss and leakage may affect efficiency in high-temperature, low-leakage designs | Prefer for cost-sensitive volume builds where 0.1°C/W RθJC margin is acceptable |
Compared with Vishay and ON Semiconductor alternatives, GBPC2506 offers the lowest specified reverse leakage and best thermal resistance, making it optimal for thermally constrained or ultra-low-standby-loss applications where reliability under sustained load is critical.

FAQ
What is the maximum junction temperature rating for GBPC2506?
The GBPC2506 has a maximum junction temperature (TJ) of +150°C and a minimum storage temperature of -55°C. This wide operating range supports deployment in industrial environments with elevated ambient temperatures. Thermal design must ensure that actual junction temperature stays within this limit under worst-case load and ambient conditions, using the 1.5°C/W RθJC value and measured case temperature.
Does GBPC2506 require a heatsink for 25A continuous operation?
Yes - GBPC2506 requires external heatsinking for sustained 25A operation. At 25A and 1.1V VF, power dissipation exceeds 27W. With RθJC = 1.5°C/W, even a modest 20°C rise above ambient would exceed TJ max without additional thermal path. Mounting to a ≥100 cm² aluminum heatsink or using forced airflow is recommended for full-rated current.
Is GBPC2506 RoHS compliant and lead-free solder compatible?
Yes, GBPC2506 is RoHS compliant and features matte tin-plated leads qualified per J-STD-002 for solderability. It supports both lead-free reflow (peak 260°C) and wave soldering processes. The molding compound meets UL 94V-0 flammability standards, and the device passes JESD201 Class 1A whisker testing.
What does the "06" suffix indicate in GBPC2506?
The "06" in GBPC2506 specifies the peak repetitive reverse voltage rating: 600V. Per Taiwan Semiconductor's ordering convention, "005" = 50V, "01" = 100V, "02" = 200V, "04" = 400V, "06" = 600V, "08" = 800V, and "10" = 1000V. The "25" denotes 25A average forward current rating.
How is polarity marked on the GBPC2506 package?
GBPC2506 uses a cathode indicator: a white band or "–" symbol printed adjacent to the cathode terminal on the molded case surface. The two AC input terminals (AC1/AC2) are unmarked and interchangeable; the + terminal is the anode output, and the – terminal is the cathode output - consistent with standard bridge rectifier marking conventions.
