Product details
Overview
VS-GBPC3508W from Vishay Semiconductors is a single-phase bridge rectifier with 35 A average forward current, 800 V maximum repetitive peak reverse voltage (VRRM), and glass-passivated diode chips in an electrically insulated GBPC-W wire-lead package. It delivers reliable AC-to-DC conversion in industrial power supplies and instrumentation front-ends where thermal robustness and UL E300359 compliance are required.
For engineers reviewing the VS-GBPC3508W datasheet, VS-GBPC3508W pinout, VS-GBPC3508W application, or VS-GBPC3508W equivalent, key selection criteria include its 35 A DC output rating at 55 °C case temperature, 500 A non-repetitive surge capability at 60 Hz, and 1.4 K/W junction-to-case thermal resistance - critical for heatsink-limited designs.
Technical Context
This device implements a full-wave single-phase bridge configuration using four glass-passivated silicon diodes integrated into a molded plastic case with electrically insulated baseplate. Its wire-lead (W) termination supports soldering with Pb-free SAC305 alloy at 260–275 °C and enables direct PCB mounting without fast-on terminals.
The VS-GBPC3508W operates across -55 °C to +150 °C junction temperature range and sustains 2700 V RMS isolation between baseplate and terminals. Its forward voltage drop is specified at 1.1 V (TJ = 25 °C, IFM = IF(AV)), with low-level threshold voltage of 0.77 V and high-level slope resistance of 3.867 mΩ at maximum junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO | 35 A average DC output current at TC = 55 °C - defines continuous load capacity under heatsink-limited thermal conditions |
| VRRM | 800 V maximum repetitive peak reverse voltage - sets safe AC input voltage ceiling before breakdown |
| IFSM | 500 A peak non-repetitive surge current at 60 Hz, t = 8.3 ms - determines short-circuit withstand capability |
| RthJC | 1.4 K/W junction-to-case thermal resistance - quantifies heat transfer efficiency to external heatsink |
| VF | 1.1 V maximum forward voltage drop at TJ = 25 °C and rated current - directly impacts conduction loss and thermal design |
| VINS | 2700 V RMS isolation voltage - ensures safety compliance for primary-side mounting on grounded heatsinks |
Pinout & Package
The VS-GBPC3508W uses the GBPC-W package: a compact, electrically insulated molded plastic housing with four 1.0 mm diameter wire leads (AC1, AC2, (+), (−)), 28.55 mm × 17.9 mm footprint, and center-mounting hole (Ø 2.4 mm). Weight is 16 g; mounting torque is 2.0 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC input terminal 1 | One leg of AC input; connects to transformer secondary or line input; shares internal diode anode/cathode node |
| AC2 | AC input terminal 2 | Second leg of AC input; completes full-wave bridge input path; electrically isolated from baseplate |
| (+) | Positive DC output | Anode of output diodes; delivers rectified positive voltage; must be routed with low-inductance trace for stability |
| (−) | Negative DC output / common return | Cathode of output diodes; serves as system ground reference; ties to heatsink only if baseplate isolation is maintained |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated diode chips | Enhanced reliability and moisture resistance vs. epoxy-passivated devices; qualified for industrial environments |
| Electrically insulated case | Enables direct mounting to grounded heatsinks without additional insulation hardware; reduces BOM and assembly cost |
| UL E300359 approval | Validates safety compliance for end-equipment certification in North America; eliminates need for separate isolation testing |

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 |
|---|---|---|---|
| GBPC3508W | Same electrical specs and GBPC-W package; identical Vishay part number without "VS-" prefix - direct manufacturer variant | No functional difference; used interchangeably in Vishay's own reference designs and distributor listings | Select when sourcing from authorized channels requiring exact OEM part marking |
| ON Semiconductor NGBPC3508W | 35 A / 800 V rating; same GBPC-W outline but higher RthJC (1.6 K/W); 450 A IFSM at 60 Hz vs. 500 A | Suitable for lower-power or less thermally constrained designs; not recommended for sustained 35 A operation near TC = 55 °C | Choose for cost-sensitive applications with relaxed thermal margins and legacy ON Semi BOMs |
Compared with VS-GBPC3508W, GBPC3508W offers identical performance and fit, while NGBPC3508W trades 100 A lower surge rating and +0.2 K/W thermal resistance for potential cost advantage - making it viable only where thermal headroom exceeds 10 °C and surge events are infrequent.

FAQ
What is the maximum average forward current rating for VS-GBPC3508W?
The VS-GBPC3508W has a maximum average forward current (IO) of 35 A at a case temperature (TC) of 55 °C. At higher case temperatures, derating applies - e.g., 28 A at TC = 80 °C per Fig. 6 in the datasheet. This rating assumes resistive or inductive loads; for capacitive loads, the limit drops to 28 A at TC = 55 °C. The VS-GBPC3508W must be mounted on a heatsink to sustain this current continuously.
Does VS-GBPC3508W support lead-free soldering processes?
Yes, VS-GBPC3508W supports Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures of 260–275 °C, as confirmed in the "Nickel plated terminals" specification. Its terminals are fully compatible with standard reflow profiles compliant with IPC-J-STD-020, and no special preheat or cooling ramp rates are required beyond those defined for Level 3a moisture sensitivity.
What is the isolation voltage rating of VS-GBPC3508W?
The VS-GBPC3508W provides 2700 V RMS isolation between its baseplate and all terminals (AC1, AC2, (+), (−)) at 50 Hz for 1 second, per the VINS specification. This isolation enables safe mounting to grounded metal chassis or heatsinks without additional insulating hardware, satisfying reinforced insulation requirements in IEC 62368-1 and IEC 61800-5-1 applications.
How does the thermal resistance of VS-GBPC3508W compare to VS-GBPC2508W?
VS-GBPC3508W has a junction-to-case thermal resistance (RthJC) of 1.4 K/W, while VS-GBPC2508W is rated at 1.7 K/W - a 17.6% improvement. This lower RthJC reflects optimized die attachment and internal thermal path design in the 35 A version, allowing higher power dissipation within the same GBPC-W footprint and enabling more compact thermal solutions at equivalent load currents.
Is VS-GBPC3508W certified for use in UL-listed end equipment?
Yes, VS-GBPC3508W carries UL E300359 recognition, confirming compliance with UL 60747-4 for semiconductor devices. This certification permits its use in UL-listed end equipment without requiring additional component-level investigation, streamlining safety approvals for power supplies, motor drives, and industrial controls that incorporate the VS-GBPC3508W.
