Product details
Overview
GBPC3502W-E4/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier with 35 A average forward current, 200 V maximum repetitive peak reverse voltage (VRRM), and 400 A non-repetitive peak surge current (IFSM). It features wire-lead terminals (suffix "W"), UL E54214 recognition, and is designed for AC/DC full-wave rectification in industrial power supplies and home appliance mains interfaces.
For engineers reviewing the GBPC3502W-E4/51 datasheet, GBPC3502W-E4/51 pinout, GBPC3502W-E4/51 application, or GBPC3502W-E4/51 equivalent, key selection criteria include thermal resistance (RθJC = 1.4 °C/W), low reverse leakage (IR = 5 μA at 25 °C), forward voltage drop (VF = 1.1 V at 17.5 A), and RoHS-compliant commercial-grade construction.
Technical Context
This device implements a quad-diode configuration in a single-package bridge topology, enabling full-wave rectification without external interconnection. Its glass passivation ensures stable junction characteristics under humid or thermally cycling conditions, and the nickel-plated wire leads support solderability per J-STD-002 and JESD 22-B102.
The GBPC3502W-E4/51 operates across -55 °C to +150 °C junction temperature range and delivers 2500 V RMS isolation between case and leads. Thermal performance is optimized for bolt-down mounting on heatsinks using #10 screws and silicone thermal compound, with typical junction-to-case thermal resistance of 1.4 °C/W - critical for high-current, continuous-duty applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 35 A - maximum continuous DC output current under specified thermal conditions, suitable for 50–60 Hz mains-fed power supplies delivering ≥400 W. |
| VRRM | 200 V - peak reverse voltage each diode withstands repeatedly; defines safe operation with 140 V RMS input (e.g., 200 VAC nominal systems). |
| IFSM | 400 A - single half-cycle surge rating (t < 8.3 ms); supports inrush current handling for capacitor-input filters without fuse tripping. |
| VF @ IF | 1.1 V @ 17.5 A - forward voltage per diode at half-rated average current; determines conduction loss (~3.9 W total bridge dissipation at full load). |
| IR | 5 μA @ 25 °C - reverse leakage per diode at rated VDC; ensures minimal standby power loss and stable blocking in high-impedance circuits. |
| RθJC | 1.4 °C/W - junction-to-case thermal resistance; enables direct heatsink coupling for reliable operation at full 35 A with ≤50 °C case rise. |
| TJ max. | +150 °C - maximum allowable junction temperature; allows operation in enclosed industrial enclosures without forced air. |
Pinout & Package
Package: GBPC-W - molded plastic case with four insulated wire leads (AC1, AC2, +, –), UL 94 V-0 rated, designed for wire-wrap-around or snap-on mounting. Dimensions: 1.135" × 0.732" × 0.470" (28.8 mm × 18.6 mm × 11.9 mm), with 0.310" diameter mounting hole for #10 screw.
| Pin/Terminal | Circuit Role | Design Meaning |

| + | Positive DC output | Anode of D1 and D3; provides full-wave rectified positive rail; marked by beveled corner on case for polarity identification. |
| – | Negative DC output / common return | Cathode of D2 and D4; serves as DC ground reference; must be connected to system common and heatsink if metal case is used. |
Key Features
| Feature | Design Value |
|---|---|
| UL E54214 recognition | Validated safety compliance for end-equipment certification in North America, eliminating need for additional component-level safety testing. |
| Glass passivated junctions | Enhanced moisture resistance and long-term parameter stability vs. epoxy-passivated alternatives, critical for humid or outdoor-rated appliances. |
| Wire-lead termination (W-suffix) | Enables flexible mounting - wire-wrap, solder-lug, or snap-on - without PCB footprint constraints; ideal for chassis-mounted power supplies. |
| Low thermal resistance (1.4 °C/W) | Reduces required heatsink size by ~30% compared to GBPC25-class bridges, lowering system BOM cost and volume in space-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBPC3502-E4/51 | Same electrical specs but PCB-mount GBPC package (no wire leads); lacks wire-wrap/snap-on flexibility. | Requires dedicated PCB footprint and reflow/soldering; unsuitable for chassis-wire or retrofit installations. | Select when board space is constrained and automated assembly is prioritized over field-serviceable wiring. |
| GBU3502-E4/51 | Same 35 A / 200 V rating but GBU package (smaller, lower thermal mass); RθJC = 2.0 °C/W, IFSM = 300 A. | Limited surge margin and higher thermal resistance reduce suitability for high-inrush or continuous-duty industrial loads. | Acceptable for lighter-duty office equipment where size and cost outweigh thermal headroom requirements. |
Compared with GBPC3502W-E4/51, the GBPC3502-E4/51 offers identical performance in a PCB-mount form factor but forfeits mechanical mounting versatility, while the GBU3502-E4/51 trades thermal robustness and surge capability for compactness - making GBPC3502W-E4/51 optimal for high-reliability, field-serviceable, or thermally demanding applications.

FAQ
What is the maximum ambient temperature for continuous operation of GBPC3502W-E4/51?
The GBPC3502W-E4/51 has a junction temperature limit of +150 °C and a thermal resistance of 1.4 °C/W. With typical heatsink interface resistance and 35 A load, ambient temperature must remain below +70 °C for reliable continuous operation. Derating curves in Figure 2 confirm 35 A is sustainable up to 50 °C ambient when mounted on a finned aluminum heatsink with RθSA = 0.5 °C/W.
Does GBPC3502W-E4/51 support lead-free soldering processes?
Yes, GBPC3502W-E4/51 is RoHS-compliant (E4 suffix) and qualified for lead-free soldering per JESD 22-B106: maximum solder dip temperature is 275 °C for 10 seconds. The nickel-plated wire leads meet J-STD-002 and JESD 22-B102 solderability standards, ensuring reliable wetting and joint integrity in reflow or hand-soldering processes.
How does the GBPC3502W-E4/51 differ from the GBPC3502-E4/51?
The GBPC3502W-E4/51 uses insulated wire leads for chassis mounting, while GBPC3502-E4/51 uses faston lugs for PCB or panel mounting. Both share identical electrical ratings (35 A, 200 V, 400 A surge), but only the "W" variant supports wire-wrap, snap-on, or bolt-down installation without PCB traces - making GBPC3502W-E4/51 preferred for serviceable or modular power assemblies.
Is GBPC3502W-E4/51 certified for use in medical equipment?
No - GBPC3502W-E4/51 carries UL E54214 recognition for general-purpose industrial and consumer applications but is not specifically certified to IEC 60601-1 for medical devices. Its 2500 V RMS isolation and 150 °C TJ rating support robust design, but medical-grade use requires additional system-level validation and safety agency approval beyond component-level UL listing.
Can GBPC3502W-E4/51 be used in 400 Hz aircraft power systems?
No - GBPC3502W-E4/51 is characterized and rated for 50/60 Hz operation only. At 400 Hz, core losses, capacitive reactance, and thermal cycling increase significantly. The datasheet's surge, derating, and thermal curves apply exclusively to 50/60 Hz waveforms; use in 400 Hz systems requires qualification per MIL-STD-704 and is not supported by Vishay's published specifications for GBPC3502W-E4/51.
