Taiwan Semiconductor Corporation GBPC1501M

Overview

GBPC1501M from Taiwan Semiconductor is a 15A, 100V glass-passivated single-phase bridge rectifier in GBPC-M package with integral 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 power supplies.

For engineers reviewing the GBPC1501M datasheet, GBPC1501M pinout, GBPC1501M application, or GBPC1501M equivalent, key selection criteria include peak repetitive reverse voltage (100V), average forward current (15A), surge capability (300A @ 8.3ms), thermal performance, and cathode-terminal orientation in GBPC-M configuration.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single quad configuration with glass-passivated junctions for enhanced reliability under thermal cycling and humidity stress. Its GBPC-M mechanical variant features cathode terminals parallel to anode terminals and a molded UL 94V-0 compound housing.

Designed for high-efficiency linear and switching power conversion, it supports continuous conduction mode operation up to 150°C junction temperature and delivers low forward voltage drop (≤1.1V @ 7.5A) with minimal thermal resistance (1.5°C/W) enabling direct heatsink mounting without additional insulation.

FAQ

What is the maximum junction temperature rating for GBPC1501M?

The GBPC1501M has a maximum junction temperature (TJ max) of +150°C, allowing reliable operation in high-ambient-temperature environments such as enclosed industrial control cabinets or outdoor lighting fixtures. This rating is validated per TSC's absolute maximum ratings table and supports continuous operation up to rated current when thermal resistance limits are observed. GBPC1501M must be mounted to a heatsink capable of maintaining case temperature within safe limits.

Does GBPC1501M have UL recognition?

Yes, GBPC1501M is UL Recognized under File # E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for use in end-equipment safety certification. This applies to the entire GBPC15, 25, 35 series including the GBPC1501M variant, and covers flammability (UL 94V-0), terminal plating (J-STD-002), and whisker resistance (JESD201 Class 1A).

What does the "M" suffix indicate in GBPC1501M?

The "M" suffix in GBPC1501M denotes the GBPC-M mechanical configuration: a molded package with cathode terminals oriented parallel to anode terminals, distinct from GBPC-W (wire structure) and standard GBPC (no suffix). This configuration enables specific PCB layout compatibility and direct heatsink mounting per TSC mechanical drawing HQ2SD07-GBPCM-055 REV A.

What is the forward voltage drop of GBPC1501M at rated current?

At IF = 7.5A and TJ = 25°C, GBPC1501M exhibits a maximum forward voltage drop (VF) of 1.1 V per diode - resulting in ~2.2 V total bridge drop under typical half-cycle conduction. This value is measured under pulsed conditions (PW = 0.3ms) and remains stable across operating temperature due to glass-passivated junction design.

Is GBPC1501M RoHS compliant?

Yes, GBPC1501M is RoHS compliant per EU Directive 2011/65/EU, as confirmed in TSC's official documentation for the GBPC15, 25, 35 series. The molding compound, lead finish (matte tin), and internal construction contain no restricted substances above threshold limits, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly.
