Product details
Overview
GBPC4001M from Taiwan Semiconductor is a 40A, 100V glass-passivated single-phase 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 AC-DC front-end stages of industrial switching mode power supplies.
For engineers reviewing the GBPC4001M datasheet, GBPC4001M pinout, GBPC4001M application, or GBPC4001M equivalent, key selection criteria include repetitive peak reverse voltage (100 V), average forward current (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. 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-enabling direct heatsink mounting with ≤20 in-lbs torque and supporting high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 40 A - continuous DC output current capability at case temperature ≤75°C |
| VRRM | 100 V - maximum non-repetitive reverse voltage the device blocks without breakdown |
| IFSM | 400 A - withstands 8.3 ms half-sine surge, critical for inrush protection in SMPS input stages |
| RθJC | 1.5 °C/W - enables efficient heat transfer to external heatsink, limiting junction rise to 60°C at 40A |
| VF per diode | 1.1 V max at 20A, 25°C - determines conduction loss (≈88 W total for full-wave rectification at 40A) |
| TJ max | +150°C - defines upper operating limit for junction temperature under derated conditions |
Pinout & Package
Package: GBPC40-M - molded plastic case with integral heatsink, 29.0 × 28.5 mm footprint, cathode terminals parallel to anode terminals, chamfered corner cathode indicator, and four mounting holes (Ø5.59 mm). Weight: 17.3 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same 40 A / 100 V rating, but GBU package lacks integral heatsink (RθJC = 2.5°C/W); lead-free, RoHS-compliant | Requires external heatsink for >25 A continuous operation; less suitable for space-constrained SMPS | Select GBPC4001M when integrated thermal management and mounting flexibility are required |
| KBU4B (Comchip) | 40 A / 100 V, KBU package with heatsink tab; slightly higher VF (1.15 V max); UL recognized (E316172) | Similar mechanical mounting but different terminal orientation; lower surge rating (350 A vs. 400 A) | Choose GBPC4001M for higher surge immunity and tighter thermal performance in high-reliability AC-DC converters |
Compared with GBU4K and KBU4B, GBPC4001M delivers superior thermal performance (1.5°C/W), higher surge tolerance (400 A), and universal mounting-making it optimal for compact, high-efficiency industrial power supplies where heatsink real estate and inrush robustness are constrained.

FAQ
What is the maximum junction temperature rating for GBPC4001M?
The GBPC4001M has a maximum junction temperature (TJ max) of +150°C. This rating allows sustained operation in high-ambient environments such as enclosed industrial power supplies or outdoor LED drivers. Derating curves in the datasheet define allowable forward current versus case temperature, with full 40 A rated only below 75°C case temperature. Exceeding TJ max risks irreversible parametric shift or thermal runaway.
Does GBPC4001M support direct heatsink mounting?
Yes, GBPC4001M supports direct heatsink mounting via its integral heatsink structure and four Ø5.59 mm mounting holes. The datasheet specifies a maximum mounting torque of 20 in-lbs and confirms compatibility with standard heatsink interface materials. Its RθJC of 1.5°C/W is measured under this mounting condition, making it suitable for thermally demanding applications without additional thermal interface layers.
What does the "M" suffix indicate in GBPC4001M?
The "M" suffix in GBPC4001M denotes the GBPC40-M mechanical variant, where cathode terminals are oriented parallel to anode terminals-distinct from the standard GBPC40 version with perpendicular orientation. This layout optimizes PCB routing in high-density power boards and aligns with specific heatsink footprints. The "01" in the part number indicates 100 V VRRM rating per the ordering code convention.
Is GBPC4001M RoHS compliant and lead-free?
Yes, GBPC4001M is RoHS compliant and manufactured with lead-free terminations. The matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94V-0 flammability standards. Taiwan Semiconductor's documentation confirms full compliance with Directive 2011/65/EU and subsequent amendments, including exemption 7a for lead in high-melting-temperature type solders.
How is polarity marked on the GBPC4001M package?
Polarity on GBPC4001M is indicated by a chamfered corner adjacent to the cathode (−) terminal and standardized marking: "+" symbol near the positive output terminal and "−" symbol near the negative output terminal. The AC input terminals are labeled "AC" on the body. These markings conform to IEC 60747-2 and are visible without magnification, supporting automated optical inspection and manual assembly verification.
