Product details
Overview
GBPC4008M from Taiwan Semiconductor is a 40A, 800V standard bridge rectifier in GBPC40-M package with integral heatsink, glass-passivated junctions, and 400A peak surge capability-used in AC-DC conversion stages of industrial SMPS and motor drive front-ends.
For engineers reviewing the GBPC4008M datasheet, GBPC4008M pinout, GBPC4008M application, or GBPC4008M equivalent, key selection factors include its 1.5°C/W junction-to-case thermal resistance, 1.1V max forward voltage at 20A, 10µA max reverse leakage per diode, UL Recognized status (E-326243), and RoHS-compliant matte tin-plated terminals.
Technical Context
This quad-configuration bridge rectifier integrates four silicon diodes in a single molded package with cathode parallel to anode terminal orientation (GBPC40-M variant). It operates across -55°C to +150°C junction temperature range and supports universal mounting: snap-on, wrap-around, solder, or PCB.
Thermal performance is defined by RθJC = 1.5°C/W, enabling high-power dissipation without external heatsink in moderate-duty cycles. Electrical behavior follows standard silicon PN-junction characteristics-forward conduction with 1.1V drop at rated current, and reverse blocking up to 800V repetitive peak voltage (VRRM).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC408 | Same 40A/800V rating, but GBPC40 (not GBPC40-M) package: cathode perpendicular to anode; RθJC = 1.7°C/W | Requires different mechanical layout due to terminal orientation; slightly higher thermal resistance limits high-duty-cycle use | Acceptable where board space allows reorientation and thermal margin ≥ 0.2°C/W is available |
| ON Semiconductor GBU4J | Lower current rating (4A), smaller GBU package, no integral heatsink; VRRM = 600V | Not suitable for 40A continuous loads; intended for low-power auxiliary supplies, not main DC bus | Only viable for prototyping or low-power subsystems-not a functional replacement for GBPC4008M |
Compared with GBPC4008M, Vishay GBPC408 offers identical electrical ratings but requires mechanical redesign due to terminal geometry and has inferior thermal performance, while ON Semi GBU4J is underspecified for current, voltage, and thermal demands-making GBPC4008M the only production-ready option for 40A/800V industrial rectification.

FAQ
What is the maximum junction temperature rating for GBPC4008M?
The GBPC4008M has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating applies across the full operating range and defines the upper thermal limit before irreversible degradation occurs. Derating curves in the datasheet specify reduced current capacity above 75°C case temperature. GBPC4008M must be mounted with appropriate thermal interface to maintain TJ ≤ 150°C under worst-case load conditions.
Does GBPC4008M have UL recognition and what is the file number?
Yes, GBPC4008M is UL Recognized under file # E-326243, as confirmed in the Taiwan Semiconductor GBPC40/50 Series datasheet (Version G2211). This recognition covers the GBPC40-M package variant and validates compliance with UL 60950-1 and UL 62368-1 for end-equipment safety certification. The UL mark appears on product marking diagrams and packaging documentation for GBPC4008M units.
What is the forward voltage drop specification for GBPC4008M at rated current?
The GBPC4008M has a maximum forward voltage (VF) of 1.1 V per diode at IF = 20 A and TJ = 25°C, as specified in the Electrical Specifications table. This value reflects worst-case conduction loss under pulsed test conditions (PW = 0.3 ms). At full 40A average current and elevated temperature, actual VF increases-designers should reference the Typical Forward Characteristics curve (Figure 4) for accurate thermal modeling of GBPC4008M.
How is the polarity marked on the GBPC4008M package?
GBPC4008M uses a channeled corner and "–" symbol as the cathode indicator, located adjacent to the negative DC output terminal on the molded case. The marking diagram in the datasheet (Page 4) confirms this orientation for the GBPC40-M variant. Polarity is also reinforced by physical terminal layout: the "+" and "–" terminals are labeled on the heatsink surface, and AC terminals are symmetrically placed opposite the DC outputs. Always verify polarity with a multimeter before PCB integration.
What mounting methods are supported by GBPC4008M?
GBPC4008M supports four mechanical mounting options: snap-on (to chassis or heatsink clips), wrap-around (terminal bent around mounting post), solder (direct lead soldering), and PCB mounting (through-hole insertion with pad clearance per outline drawing). All methods are validated per Mechanical Data section, with maximum mounting torque limited to 20 in-lbs. The GBPC40-M variant's terminal geometry-cathode parallel to anode-is optimized for consistent alignment across all four methods.
