Taiwan Semiconductor Corporation GBPC25005

Overview

GBPC25005 from Taiwan Semiconductor is a 25A, 50V standard bridge rectifier in GBPC package with quad configuration, glass-passivated junctions, 1.1V max forward voltage at 12.5A, and <5µA reverse current at rated voltage - used in AC-DC converters and switching mode power supplies.

For engineers reviewing the GBPC25005 datasheet, GBPC25005 pinout, GBPC25005 application, or GBPC25005 equivalent, key selection factors include peak repetitive reverse voltage (50V), average forward current (25A), thermal resistance (1.5°C/W), surge rating (300A @ 8.3ms), and UL recognition (E-326243).

Technical Context

This device integrates four diodes in a single-phase full-wave bridge configuration with a molded heatsink for low thermal resistance. Its glass-passivated junction ensures stable reverse leakage (<5µA) and high reliability under thermal cycling.

The GBPC25005 operates across –55°C to +150°C junction temperature range and supports high surge capability (300A IFSM) without fusing up to 373 A²s, making it suitable for transient-heavy industrial AC input stages.

Key Specifications

Pinout & Package

GBPC25005 uses the GBPC through-hole package with integral heatsink and four terminals: two AC inputs (A1, A2), one DC+ (cathode), and one DC– (anode). Polarity is marked on case with cathode indicator.

FAQ

What is the maximum junction temperature rating for GBPC25005?

The GBPC25005 has a maximum junction temperature (TJ) rating of +150°C, allowing continuous operation in high-ambient environments such as enclosed power supplies or industrial control cabinets. This rating is validated across its full current and voltage operating range and supports derating curves shown in the datasheet Figure 1. The device must be mounted to a heatsink or PCB copper area capable of maintaining TJ ≤ 150°C under worst-case load conditions. GBPC25005 maintains specified electrical parameters up to this limit.

Does GBPC25005 have UL recognition and what is the file number?

Yes, GBPC25005 is UL Recognized under file number E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for use in information technology and audio/video equipment. This recognition covers flammability (UL 94V-0 molding compound), terminal construction, and dielectric strength. The UL mark applies to the GBPC package variant and is documented in Taiwan Semiconductor's certification records. GBPC25005 may be used in end products requiring UL listing without additional component-level investigation.

What is the forward voltage specification for GBPC25005 and under what test conditions?

The GBPC25005 has a maximum forward voltage (VF) of 1.1 V per diode, measured at IF = 12.5 A and TJ = 25°C using a 0.3 ms pulse width. This value reflects conduction loss under typical half-load conditions and scales predictably with current and temperature. At higher junction temperatures (e.g., 125°C), VF decreases slightly (~2 mV/°C), while at lower temperatures it increases. GBPC25005's VF directly determines power dissipation (P = VF × IF) in the bridge during operation.

Is GBPC25005 compatible with lead-free reflow soldering processes?

Yes, GBPC25005 features matte tin-plated leads qualified per J-STD-002 for solderability and compliant with JEDEC J-STD-020 moisture sensitivity level (MSL) 1 - unlimited floor life at ≤30°C/85% RH. It withstands peak reflow temperatures up to 260°C for 10 seconds, meeting IPC/JEDEC standards for lead-free assembly. The GBPC package's thermal mass requires adequate preheat and soak time to avoid thermal shock. GBPC25005 is fully compatible with standard SMT reflow profiles when mounted on appropriately sized copper pads.

What mechanical mounting torque is recommended for GBPC25005?

The recommended maximum mounting torque for GBPC25005 is 20 in-lbs (2.26 N·m) when securing the integral heatsink to an external metal chassis or heatsink. Exceeding this torque risks cracking the molded epoxy body or deforming the leadframe, compromising mechanical integrity and thermal performance. Mounting hardware must align with the 5.59 mm diameter mounting holes specified in the GBPC outline drawing (HQ2SD07-GBPC-054 REV A). GBPC25005's thermal path relies on uniform pressure across the heatsink base, so consistent torque application is essential.
