Product details
Overview
GBPC1504M from Taiwan Semiconductor is a 15A, 400V glass-passivated quad bridge rectifier in GBPC-M package, featuring 1.5°C/W junction-to-case thermal resistance and <5μA reverse leakage at rated voltage, used in AC-DC converters and switching mode power supplies.
For engineers reviewing the GBPC1504M datasheet, GBPC1504M pinout, GBPC1504M application, or GBPC1504M equivalent, key selection factors include peak repetitive reverse voltage (400V), average forward current (15A), surge capability (300A @ 8.3ms), thermal performance, and GBPC-M terminal orientation for heatsink mounting.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single molded GBPC-M package with cathode terminals parallel to anode leads, enabling compact AC input stage rectification. Its glass-passivated junction ensures stable reverse characteristics and low IR across temperature.
Designed for high-reliability industrial power conversion, it supports continuous operation up to 150°C junction temperature and delivers 373 A²s fusing rating under short-duration surges, meeting UL 94V-0 flammability and JESD201 Class 1A whisker requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1504 | Same 15A/400V rating but GBU package (lower thermal resistance: 1.2°C/W); no integral heatsink | Requires external heatsink; better suited for forced-air or compact board-level cooling | Choose GBU1504 when board space allows discrete heatsink mounting and lower RθJC is prioritized |
| KBP1504 | 15A/400V in KBP package; higher RθJC (2.0°C/W); lead-free, RoHS-compliant | Limited thermal performance; suitable for lower-duty-cycle or ambient-cooled applications | Choose KBP1504 where cost sensitivity outweighs thermal headroom and no bolt-down heatsink is used |
Compared with GBPC1504M, GBU1504 offers superior thermal dissipation but lacks integrated heatsink mounting, while KBP1504 trades thermal capability for lower cost and simpler assembly-GBPC1504M uniquely balances bolt-down heatsinking, UL recognition, and 1.5°C/W RθJC in a single package.

FAQ
What is the maximum junction temperature rating for GBPC1504M?
The GBPC1504M has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows continuous operation in high-ambient environments such as enclosed industrial power supplies. Derating curves confirm usable current down to 0A at 150°C case temperature. GBPC1504M must be mounted to a heatsink to maintain TJ within limits under full load.
Does GBPC1504M have UL recognition?
Yes, GBPC1504M is UL Recognized under File #E-326243, as documented in the Taiwan Semiconductor GBPC15/25/35 Series datasheet. This applies to the entire GBPC-M variant family, confirming compliance with UL 60950-1 and UL 62368-1 for end-equipment safety certification. The molding compound also meets UL 94V-0 flammability requirements.
What does the "M" suffix indicate in GBPC1504M?
The "M" suffix in GBPC1504M denotes the GBPC-M package variant, where cathode terminals are oriented parallel to anode leads-enabling direct bolt-down mounting to a heatsink. This differs from GBPC-W (wire structure) and standard GBPC (no orientation specification). Mechanical drawings confirm the M variant's terminal alignment and heatsink interface geometry.
What is the forward voltage drop of GBPC1504M at rated current?
GBPC1504M exhibits a maximum forward voltage (VF) of 1.1 V per diode at IF = 7.5 A and TJ = 25°C, as specified in the electrical characteristics table. At full 15A average current and elevated temperature, VF increases slightly due to thermal effects, but remains within design margins for typical SMPS efficiency targets. Pulse testing conditions (0.3ms PW) ensure repeatability.
Is GBPC1504M RoHS compliant and lead-free?
Yes, GBPC1504M is RoHS compliant and features matte tin-plated leads that meet J-STD-002 solderability requirements. It also passes JESD201 Class 1A whisker testing, confirming long-term reliability in lead-free assembly processes. Taiwan Semiconductor confirms full compliance in the product revision history and ordering information section of the GBPC series datasheet.
