Product details
Overview
GBPC3508-E4/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier rated for 35 A average forward current, 800 V maximum repetitive peak reverse voltage, and 400 A non-repetitive surge current. It features low thermal resistance (1.4 °C/W), typical forward voltage of 1.1 V at 17.5 A, and operates up to 150 °C junction temperature - used in industrial AC/DC power supplies requiring robust full-wave rectification.
For engineers reviewing the GBPC3508-E4/51 datasheet, GBPC3508-E4/51 pinout, GBPC3508-E4/51 application, or GBPC3508-E4/51 equivalent, key selection criteria include RMS isolation voltage (2500 V), reverse leakage (5 μA at 25 °C), quad-diode configuration, UL E54214 recognition, and compatibility with snap-on/wire-wrap/PCB mounting.
Technical Context
This device integrates four silicon diodes in a single-phase full-bridge configuration, enabling AC-to-DC conversion without external interconnection. Its glass passivation ensures stable reverse characteristics and high reliability under thermal cycling and humid conditions.
The GBPC3508-E4/51 uses a GBPC package with nickel-plated faston lugs, supports bolt-down heatsinking (max 20 in-lbs torque), and meets UL 94 V-0 flammability rating. Thermal performance is optimized for use with aluminum finned heatsinks (e.g., 6 × 2.2 × 2.2 inch) and requires silicone thermal compound for rated power dissipation.

|---|---|---|---|
| GBPC3508W-E4/51 | Wire-lead termination instead of faston lugs; 13.8 g weight vs. 15.79 g; same electrical specs | Designed for through-hole PCB or wire-wrap assembly rather than snap-on panel mounting | Select when board-level integration or manual wiring is preferred over chassis-mount faston connections |
| GBPC2508-E4/51 | Lower IF(AV) = 25 A; same VRRM = 800 V; IFSM = 300 A; RθJC = 1.9 °C/W | Suitable for lower-power designs where thermal headroom or cost optimization is prioritized | Choose when average load current remains ≤25 A and heatsink capacity is limited |
Compared with GBPC3508-E4/51, the GBPC3508W-E4/51 offers identical electrical performance but different mechanical interface, while GBPC2508-E4/51 trades 10 A current capacity and higher thermal resistance for cost and footprint reduction - both require layout review for mounting and thermal path changes.

FAQ
What is the maximum operating temperature for GBPC3508-E4/51?
The GBPC3508-E4/51 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay's thermal characterization curves and test conditions. This rating applies under proper heatsinking - for example, with a 6 × 2.2 × 2.2 inch aluminum finned plate and silicone thermal compound. Operation beyond this limit risks irreversible parametric shift or failure. Derating is required above 25 °C ambient per Fig. 2 in the datasheet. The GBPC3508-E4/51 must not be operated at TJ > 150 °C in any condition.
Does GBPC3508-E4/51 support PCB mounting?
Yes, GBPC3508-E4/51 supports PCB mounting via its universal 3-way terminals - including direct PCB insertion using the faston lugs as through-hole or surface-mount compatible features. The GBPC package outline shows 0.220-inch (5.59 mm) diameter mounting holes aligned for #10 screws, and the terminals are nickel-plated for J-STD-002 solderability. For PCB use, ensure adequate copper pour and thermal vias beneath the case to manage 1.4 °C/W junction-to-case resistance. GBPC3508-E4/51 is not a surface-mount-only part but accommodates mixed-mount strategies.
What is the reverse leakage current specification for GBPC3508-E4/51?
The GBPC3508-E4/51 specifies a maximum reverse DC current (IR) of 5.0 μA per diode at 25 °C and rated DC blocking voltage (800 V), per Vishay Document Number 88612. At elevated temperature (125 °C), IR rises to 500 μA - a design-critical parameter for low-power standby circuits. This value is measured under steady-state DC bias and reflects intrinsic silicon behavior, not package-related leakage. The GBPC3508-E4/51 achieves this performance via glass passivation, which stabilizes surface states and suppresses surface conduction paths.
Is GBPC3508-E4/51 RoHS-compliant?
Yes, GBPC3508-E4/51 is RoHS-compliant, as indicated by the "E4" suffix in its part number per Vishay's material categorization policy (Document 99912). It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and complies with EU Directive 2011/65/EU. The molding compound meets UL 94 V-0, and terminals are nickel-plated on faston lugs. GBPC3508-E4/51 is designated commercial grade and qualifies for use in consumer and industrial products requiring environmental compliance.
What is the isolation voltage rating of GBPC3508-E4/51?
The GBPC3508-E4/51 provides 2500 V RMS isolation voltage from case to leads, tested per industry-standard dielectric withstand requirements. This rating ensures safe separation between the high-voltage AC input circuitry and the grounded metal chassis or heatsink, satisfying basic insulation requirements in Class I appliances and industrial controls. The isolation is structural - achieved via creepage/clearance distances and UL 94 V-0 mold compound - and is independent of external potting or conformal coating. GBPC3508-E4/51 maintains this rating throughout its full operating temperature range (-55 °C to +150 °C).
