Taiwan Semiconductor Corporation GBPC25005M

Overview

GBPC25005M from Taiwan Semiconductor is a 25A, 50V glass-passivated quad bridge rectifier in GBPC-M package with integrally molded heatsink, 1.5°C/W junction-to-case thermal resistance, and <5µA reverse leakage at 25°C - used in AC-DC front-end stages of industrial SMPS.

For engineers reviewing the GBPC25005M datasheet, GBPC25005M pinout, GBPC25005M application, or GBPC25005M equivalent, key selection criteria include peak surge current (400A), forward voltage (≤1.1V @ 12.5A), thermal performance, RoHS compliance, and UL recognition (E-326243).

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with cathode and anode terminals brought out to screw-mountable leads. Its GBPC-M package features terminal cathode parallel to anode and matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing.

The device operates across -55°C to +150°C junction temperature range, supports 8.3ms non-repetitive surge currents up to 400A, and delivers stable rectification under high dv/dt conditions due to glass-passivated junctions and low junction capacitance (<100pF @ 1MHz).

FAQ

What is the maximum junction temperature rating for GBPC25005M?

The GBPC25005M has a maximum junction temperature (TJ) rating of +150°C and a minimum of -55°C. This wide operating range allows deployment in industrial enclosures without active cooling. Thermal derating begins above 25°C ambient, and the 1.5°C/W junction-to-case resistance must be leveraged with appropriate heatsinking to maintain safe TJ under full 25A load. GBPC25005M datasheet curves confirm usable current down to 0°C at full rating.

Does GBPC25005M support RoHS and UL compliance?

Yes, GBPC25005M is RoHS compliant and UL Recognized under file #E-326243. The molding compound meets UL 94V-0 flammability standards, and terminals pass JESD 201 Class 1A whisker testing. These certifications are documented in Taiwan Semiconductor's official GBPC series datasheet (Version M2211) and verified on authorized distributor listings. GBPC25005M is suitable for end-equipment requiring North American safety approval.

What is the forward voltage drop of GBPC25005M at rated current?

The forward voltage (VF) of GBPC25005M is guaranteed ≤1.1 V at 12.5 A and 25°C junction temperature, per the manufacturer's electrical specifications. This value reflects per-diode drop; total bridge drop is ~2.2 V under balanced load. At elevated temperatures or higher currents, VF increases slightly - typical curve data shows ~1.15 V at 12.5 A and 125°C. GBPC25005M maintains this performance across its full operating temperature range.

How does the GBPC-M package differ from GBPC-W and standard GBPC?

The GBPC-M package features cathode and anode terminals oriented parallel to each other - optimized for screw-terminal mounting with flat heatsink contact. In contrast, GBPC-W uses wire leads for through-hole PCB insertion, and standard GBPC lacks the molded heatsink geometry. GBPC25005M's GBPC-M variant includes chamfered corners, cathode indicator, and matte tin plating per J-STD-002. Mechanical drawings confirm distinct terminal pitch and mounting hole positions unique to GBPC-M.

What surge current rating does GBPC25005M support?

GBPC25005M supports a non-repetitive peak forward surge current (IFSM) of 400 A for an 8.3 ms single half-sine waveform at 25°C ambient. This rating applies under worst-case conditions - no pre-bias, no heat sinking - and is validated per JEDEC standards. The corresponding I²t rating is 664 A²s, enabling reliable handling of transformer inrush and short-duration line transients. GBPC25005M maintains this surge capability across its full -55°C to +150°C storage temperature range.
