Product details

Overview

GBPC3504M from Taiwan Semiconductor is a 35A, 400V glass-passivated single-phase bridge rectifier in GBPC-M package with integral heatsink, 1.5°C/W junction-to-case thermal resistance, and <5µA reverse leakage at rated voltage - used in industrial AC-DC converters and SMPS front-end rectification stages.

For engineers reviewing the GBPC3504M datasheet, GBPC3504M pinout, GBPC3504M application, or GBPC3504M equivalent, key selection criteria include peak repetitive reverse voltage (400V), average forward current (35A), surge capability (400A @ 8.3ms), thermal performance (R_θJC = 1.5°C/W), and GBPC-M terminal orientation for heatsink mounting.

Technical Context

This quad-diode bridge integrates four silicon junctions in a single molded package with glass passivation for stable reverse blocking and low IR. Its GBPC-M configuration positions the cathode terminal parallel to the anode for optimized mechanical mounting on heatsinks.

The device operates across –55°C to +150°C junction temperature range and delivers 1.1V typical forward voltage per diode at rated current, enabling high-efficiency rectification in continuous conduction mode power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse voltage the bridge withstands without breakdown during AC line cycling.
I_F(AV)	35 A - Continuous average forward current rating under specified thermal conditions (T_C = 100°C).
I_FSM	400 A - Peak non-repetitive surge current tolerance for 8.3 ms half-sine waveform, critical for inrush handling.
R_θJC	1.5 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting with predictable temperature rise.
V_F (per diode)	1.1 V max - Forward voltage drop at 17.5 A and 25°C, directly impacting conduction loss and efficiency.
I_R	<5 µA - Reverse leakage current per diode at rated V_RRM, ensuring low standby power loss.
T_J max	+150 °C - Maximum allowable junction temperature, defining upper thermal operating limit.

Pinout & Package

GBPC3504M uses the GBPC-M molded package with integral heatsink and matte tin-plated leads. The terminal layout features cathode and anode terminals oriented parallel for direct bolt-down mounting to external heatsinks.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay GBPC3504	Same GBPC package, identical 35A/400V ratings, but GBPC3504 uses GBPC-W (wire-lead) instead of GBPC-M terminal orientation.	Requires different heatsink interface design due to perpendicular terminal layout; not mechanically interchangeable.	Select GBPC3504M when direct bolt-down heatsink mounting with parallel terminals is required.
ON Semiconductor GBU35J	Higher V_RRM (600 V), same I_F(AV) (35 A), but GBU package lacks integral heatsink and has higher R_θJC (2.5°C/W).	Suitable where higher voltage margin is needed but thermal management requires external heatsink design.	Choose GBPC3504M when integrated heatsink and lower thermal resistance are critical for compact designs.

Compared with GBPC3504 and GBU35J, GBPC3504M offers superior thermal performance (1.5°C/W vs. ≥2.5°C/W) and mechanical compatibility with bolt-down heatsinks - making it optimal for space-constrained, high-power-density AC-DC converters requiring long-term thermal stability.

FAQ

What is the maximum junction temperature rating for GBPC3504M?

The GBPC3504M has a maximum junction temperature (T_J) of +150°C, verified per TSC's Absolute Maximum Ratings table. This rating allows sustained operation in high-ambient environments when mounted on an adequately sized heatsink. Thermal derating curves in the datasheet define safe current limits above 100°C case temperature. GBPC3504M must not exceed this limit to maintain reliability and avoid parametric shift.

Does GBPC3504M have UL recognition?

Yes, GBPC3504M is UL Recognized under File # E-326243, confirming compliance with UL 60747-1 for discrete semiconductors. This applies to the entire GBPC15/25/35 series including GBPC3504M and supports end-product safety certification in North America. The recognition covers flammability (UL 94V-0), construction, and electrical safety testing per applicable standards.

What does the "M" suffix indicate in GBPC3504M?

The "M" suffix in GBPC3504M denotes the GBPC-M package variant, where the cathode and anode terminals are oriented parallel to each other for direct bolt-down mounting to a heatsink. This differs from GBPC-W (wire leads) and standard GBPC (perpendicular terminals). The M variant is specified in TSC's Ordering Information table and confirmed in Package Outline Dimension drawing HQ2SD07-GBPCM-055 REV A.

What is the forward voltage drop of GBPC3504M at rated current?

GBPC3504M exhibits a maximum forward voltage drop of 1.1 V per diode at I_F = 17.5 A and T_J = 25°C, as specified in the Electrical Specifications table. Since the bridge contains two series diodes conducting per half-cycle, total conduction loss is approximately 2.2 V at full load. This value is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating effects.

Is GBPC3504M RoHS compliant and lead-free?

Yes, GBPC3504M is RoHS compliant and lead-free, as explicitly stated in the Features section and confirmed in the Mechanical Data table. It meets JESD201 Class 1A whisker requirements and uses matte tin-plated leads solderable per J-STD-002. No lead or other RoHS-restricted substances exceed threshold limits, and the molding compound complies with UL 94V-0 flammability rating.
