Taiwan Semiconductor Corporation GBPC40005M

Overview

GBPC40005M from Taiwan Semiconductor is a 40A, 50V glass-passivated single-phase bridge rectifier in GBPC40-M package with integral heatsink, rated for 400A non-repetitive surge current and 150°C max junction temperature, used in AC-DC conversion stages of industrial power supplies.

For engineers reviewing the GBPC40005M datasheet, GBPC40005M pinout, GBPC40005M application, or GBPC40005M equivalent, key selection criteria include peak reverse voltage (50 V), forward current rating (40 A), thermal resistance (1.5 °C/W), mounting compatibility (snap-on/wrap-around/solder/PCB), and UL recognition (E-326243).

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single quad configuration with common cathode and anode terminals, enabling full-wave AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable reverse leakage (<10 µA at 25°C) and high reliability under thermal cycling.

The GBPC40-M mechanical variant features cathode terminals parallel to anode terminals, matte tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound. Thermal performance is optimized via integrally molded heatsink yielding 1.5 °C/W junction-to-case resistance.

FAQ

What is the peak repetitive reverse voltage rating of GBPC40005M?

The GBPC40005M has a peak repetitive reverse voltage (VRRM) rating of 50 V. This value defines the maximum AC voltage the device can block during each half-cycle without entering avalanche breakdown. It is verified per Taiwan Semiconductor's G2211 specification sheet and applies under standard test conditions (TA = 25°C). The "005" suffix in GBPC40005M explicitly denotes the 50 V rating within the GBPC40 family.

Does GBPC40005M require a heatsink for 40 A continuous operation?

Yes, GBPC40005M requires a heatsink for sustained 40 A operation. Its junction-to-case thermal resistance is 1.5 °C/W, meaning even with ideal case-to-heatsink contact, self-heating exceeds safe limits without external heat dissipation. The integrally molded heatsink enables direct mounting, but system-level thermal design-including heatsink size, airflow, and ambient temperature-must be validated using the derating curve in Figure 1 of the GBPC40, 50 series datasheet.

Is GBPC40005M RoHS compliant and lead-free?

Yes, GBPC40005M is RoHS compliant and lead-free. The product documentation confirms compliance with Directive 2011/65/EU, and the matte tin-plated leads meet J-STD-002 solderability requirements. No lead or other restricted substances exceed EU-mandated thresholds, and the molding compound satisfies UL 94V-0 flammability standards-critical for environmentally regulated industrial deployments.

What does the "M" suffix in GBPC40005M indicate?

The "M" suffix in GBPC40005M specifies the GBPC40-M mechanical variant, where cathode terminals are oriented parallel to anode terminals-distinct from the standard GBPC40 orientation. This configuration simplifies PCB layout and mechanical mounting in space-constrained designs. The "M" also denotes tray packaging (50 units per tray) and adherence to JESD 201 Class 1A whisker testing for long-term solder joint reliability.

Can GBPC40005M replace GBPC4005 in a design?

GBPC40005M is functionally identical to GBPC4005 in electrical specifications (both 40 A / 50 V), but differs mechanically: GBPC40005M uses the GBPC40-M terminal orientation (cathode parallel to anode), while GBPC4005 uses standard GBPC40 layout. PCB footprint and mounting hardware must be verified for compatibility. No electrical redesign is needed, but mechanical fit and torque limits (20 in-lbs max) must be confirmed per the G2211 datasheet.
