Product details
Overview
GBPC3504-E4/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier rated for 35 A average forward current, 400 V maximum repetitive peak reverse voltage, and 400 A non-repetitive surge current. It features low thermal resistance (1.4 °C/W), 1.1 V forward voltage at 17.5 A, and 5 μA reverse leakage at 25 °C - designed for high-reliability AC/DC power conversion in industrial power supplies.
For engineers reviewing the GBPC3504-E4/51 datasheet, GBPC3504-E4/51 pinout, GBPC3504-E4/51 application, or GBPC3504-E4/51 equivalent, key selection criteria include RMS isolation voltage (2500 V), UL E54214 recognition, RoHS-compliant commercial-grade construction, and compatibility with snap-on, wire-wrap, or PCB mounting configurations.
Technical Context
This quad-diode bridge rectifier implements full-wave AC-to-DC conversion using four series-connected diodes in a single-package configuration. Its internal layout supports universal mounting via faston lugs or wire leads, with polarity marked by a beveled corner and nickel-plated terminals solderable per J-STD-002.
Thermal performance is optimized for bolt-down heatsink mounting (max 20 in-lbs torque) with silicone thermal compound; junction temperature is rated from –55 °C to +150 °C, and transient thermal impedance is characterized for pulse durations from 0.01 s to 100 s.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBPC3504W-E4/51 | Wire-lead version (GBPC-W package); same electrical specs but no faston lugs | Requires through-hole PCB mounting instead of snap-on or bolt-down heatsink attachment | Select when board-level integration is preferred over discrete heatsink mounting |
| GBU35J | Same 35 A/400 V rating but GBU package (smaller footprint, lower IFSM = 300 A) | Limited surge margin; not rated for 2500 V isolation or UL E54214 recognition | Choose only for space-constrained designs where isolation and surge robustness are secondary |
Compared with GBPC3504W-E4/51 and GBU35J, the GBPC3504-E4/51 uniquely combines UL recognition, 2500 V isolation, and 400 A surge rating in a heatsink-mountable GBPC package - making it the only option qualified for safety-critical industrial mains interfaces requiring reinforced insulation and mechanical mounting flexibility.

FAQ
What is the maximum junction temperature rating for GBPC3504-E4/51?
The GBPC3504-E4/51 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay Document Number 88612. This rating allows sustained operation in high-ambient industrial environments when mounted on a heatsink with appropriate thermal interface material. The device also supports storage down to –55 °C, making GBPC3504-E4/51 suitable for wide-temperature-range deployments.
Does GBPC3504-E4/51 meet UL safety standards?
Yes, GBPC3504-E4/51 carries UL recognition under file number E54214, confirming compliance with UL/CSA 60950-1 and UL 62368-1 for use in end-equipment power supplies. This certification covers flammability (UL 94 V-0), isolation (2500 V RMS), and construction - a key differentiator versus non-certified bridge alternatives. GBPC3504-E4/51 must be used within its published ratings to maintain UL compliance.
What is the forward voltage drop specification for GBPC3504-E4/51 at rated current?
The GBPC3504-E4/51 exhibits a maximum forward voltage drop (VF) of 1.1 V at 17.5 A per diode, measured at TA = 25 °C. This value directly determines conduction losses in the bridge - at full 35 A output, total dissipation is approximately 38.5 W. Thermal design must account for this, especially since VF increases with junction temperature, as confirmed in Figure 5 of the GBPC3504-E4/51 datasheet.
Can GBPC3504-E4/51 be mounted directly to a heatsink?
Yes, GBPC3504-E4/51 is designed for direct bolt-down heatsink mounting using a #10 screw through the central mounting hole (0.220″ diameter). Vishay specifies maximum mounting torque of 20 in-lbs and recommends silicone thermal compound between the case and heatsink surface to achieve the rated 1.4 °C/W junction-to-case thermal resistance. This mechanical interface is integral to GBPC3504-E4/51's thermal performance claims.
What does the "E4/51" suffix indicate in GBPC3504-E4/51?
The "E4" suffix denotes RoHS-compliant, commercial-grade construction with nickel-plated faston lugs, while "/51" specifies the preferred packaging code - 100 units per paper box. This ordering format aligns with Vishay's standard nomenclature for GBPC-series bridges and confirms GBPC3504-E4/51 is supplied in tape-and-reel–compatible retail packaging suitable for manual or semi-automated assembly.
