Taiwan Semiconductor Corporation GBPC5004M

Overview

GBPC5004M from Taiwan Semiconductor is a 50A, 400V glass-passivated quad bridge rectifier in GBPC40-M package with integral heatsink, 1.5°C/W junction-to-case thermal resistance, and 400A peak surge current capability-used in high-efficiency AC-DC converters and SMPS front-end rectification.

For engineers reviewing the GBPC5004M datasheet, GBPC5004M pinout, GBPC5004M application, or GBPC5004M equivalent, key selection criteria include rated forward current (50A), repetitive peak reverse voltage (400V), thermal performance (R_θJC = 1.5°C/W), mounting flexibility (snap-on/wrap-around/solder/PCB), and UL recognition (E-326243).

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with cathode-parallel-to-anode terminal orientation (GBPC40-M variant). It operates across -55°C to +150°C junction temperature range and supports 8.3ms half-sine surge currents up to 400A.

Thermal design is enabled by its integrally molded heatsink and low R_θJC of 1.5°C/W. The device uses matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker testing, with UL 94V-0 mold compound.

FAQ

What is the maximum junction temperature rating for GBPC5004M?

The GBPC5004M has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This wide operating range allows reliable use in environments such as enclosed industrial enclosures or outdoor telecom cabinets. The device's 1.5°C/W thermal resistance enables effective heat transfer to an external heatsink, helping maintain safe junction temperatures even at full 50A load under typical ambient conditions.

Does GBPC5004M require a heatsink for operation at rated current?

Yes-GBPC5004M must be mounted to an external heatsink when operating continuously at or near its 50A rated forward current. Its integrally molded heatsink reduces thermal interface resistance but does not eliminate the need for a thermally coupled external heatsink. Derating curves show that at 25°C ambient, sustained 50A operation requires case temperature ≤80°C, achievable only with adequate heatsinking per the 1.5°C/W R_θJC specification.

What does the "M" suffix indicate in GBPC5004M?

The "M" suffix in GBPC5004M denotes the GBPC40-M package variant, which features cathode-terminal orientation parallel to the anode terminal-distinct from the standard GBPC40 (non-M) variant where cathode is perpendicular. This orientation enables specific PCB layouts and mechanical mounting configurations, including wrap-around busbar connections. The "M" version also includes chamfered corners and a cathode indicator marking per TSC's mechanical drawings.

Is GBPC5004M RoHS compliant and lead-free?

Yes-GBPC5004M is RoHS compliant and lead-free per EU Directive 2011/65/EU. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94V-0 flammability standards. The device also passes JESD 201 Class 1A whisker testing, confirming robustness against tin whisker growth in long-life applications.

Can GBPC5004M replace GBPC4004M in an existing design?

No-GBPC5004M (50A) is not a direct replacement for GBPC4004M (40A) without validation. While both share identical voltage rating (400V), package (GBPC40-M), and pinout, the higher current rating increases thermal mass and alters forward voltage behavior under load. Layout, heatsink sizing, and surge protection must be re-evaluated. GBPC5004M may be used only after confirming that traces, fusing, and thermal margins accommodate the 25% higher continuous current capability of the GBPC5004M.
