Product details
Overview
VS-GBPC3504W from Vishay Semiconductors is a single-phase bridge rectifier with 35 A average forward current, 400 V maximum repetitive peak reverse voltage (VRRM), and glass-passivated diode chips in an electrically insulated, thermally efficient GBPC package. It delivers reliable AC-to-DC conversion in industrial power supplies and instrumentation front-ends where high surge tolerance and low thermal resistance are required.
For engineers reviewing the VS-GBPC3504W datasheet, VS-GBPC3504W pinout, VS-GBPC3504W application, or VS-GBPC3504W equivalent, key selection criteria include its 475 A non-repetitive surge rating at 50 Hz, 1.4 K/W junction-to-case thermal resistance, UL E300359 approval, and wire-lead terminal configuration for through-hole mounting.
Technical Context
The VS-GBPC3504W integrates four glass-passivated silicon diodes in a single-phase full-wave bridge configuration, optimized for resistive, inductive, and capacitive loads. Its electrically insulated plastic case enables direct heatsink mounting without isolation hardware, while the wire-lead (W) variant supports manual soldering or crimp termination.
Thermal performance is defined by RthJC = 1.4 K/W (DC operation) and RthCS = 0.2 K/W (greased interface), enabling sustained 35 A output at TC = 55 °C. The device sustains 475 A IFSM (t = 10 ms, 50 Hz) with I²t = 1130 A²s under no-voltage-reapplied conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-phase bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-GBPC3504A | Same electrical specs but fast-on (push-on) terminals instead of wire leads; RthJC = 1.4 K/W unchanged | Designed for quick-connect terminal blocks in panel-mounted equipment; not suitable for PCB through-hole or hand-soldered assemblies | Select VS-GBPC3504A only when using insulated spade connectors; VS-GBPC3504W remains preferred for manual assembly or crimped wire harnesses. |
| ON Semiconductor GBPC3504W | Identical pinout, package, and core ratings (35 A, 400 V); differs in thermal impedance curve shape and I²t tolerance (1100 A²s vs. 1130 A²s) | Approved for automotive-grade qualification per AEC-Q101; not UL E300359 certified | Choose ON Semi GBPC3504W for automotive body electronics; retain VS-GBPC3504W for UL-certified industrial or consumer systems requiring safety agency validation. |

FAQ
What is the maximum case temperature for continuous operation of the VS-GBPC3504W?
The VS-GBPC3504W supports continuous operation at a maximum case temperature (TC) of 55 °C when delivering its rated 35 A average forward current. This limit is specified in the Major Ratings table and reflects thermal equilibrium under DC conditions with proper heatsinking. Exceeding 55 °C requires derating per the Current Ratings Characteristics curves in the datasheet.
Does the VS-GBPC3504W require an insulating pad when mounted to a metal heatsink?
No, the VS-GBPC3504W does not require an insulating pad because its plastic case provides electrical isolation between the internal diode die and the mounting surface. The datasheet explicitly states "electrically insulated case" and specifies 2700 V RMS isolation voltage, enabling direct metal-to-plastic contact for thermal conduction without compromising safety or functionality.
What is the forward voltage drop of the VS-GBPC3504W at full rated current?
The VS-GBPC3504W has a maximum forward voltage drop (VFM) of 1.1 V at TJ = 25 °C and instantaneous forward current equal to the average forward current (IF(AV)). At 35 A DC output, this results in ≤ 38.5 W total conduction loss across all four diodes, assuming balanced current sharing within the bridge.
Is the VS-GBPC3504W RoHS-compliant and lead-free solder compatible?
Yes, the VS-GBPC3504W is RoHS-compliant and features nickel-plated terminals compatible with lead-free solder alloys including Sn/Ag/Cu (SAC305). The datasheet specifies a recommended solder temperature range of 260 °C to 275 °C, confirming suitability for standard lead-free reflow and hand-soldering processes without terminal degradation.
How does the VS-GBPC3504W differ from the VS-GBPC2504W in practical design use?
The VS-GBPC3504W delivers 35 A average forward current versus 25 A for the VS-GBPC2504W, with identical 400 V VRRM, package outline, and wire-lead configuration. Its lower RthJC (1.4 K/W vs. 1.7 K/W) and higher IFSM (475 A vs. 400 A) allow greater power density and surge margin-making the VS-GBPC3504W preferable for designs approaching 800–1000 W output or subject to frequent cold starts.
