Product details
Overview
GBPC3510 from Diodes Incorporated is a 35A glass-passivated single-phase bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 17.5A per diode, and 400A non-repetitive surge rating - used in industrial AC/DC power supplies, motor drive front-ends, and welding equipment input stages.
For engineers reviewing the GBPC3510 datasheet, GBPC3510 pinout, GBPC3510 application, or GBPC3510 equivalent, key selection criteria include thermal resistance (1.2°C/W junction-to-case), case isolation voltage (1500V), mounting torque limit (8.0 in-lbs), and UL recognition (E94661) for safety-critical power conversion designs.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single molded plastic package with internal heatsink and metal base for direct PCB mounting via #10 screw. It operates across –65°C to +150°C and supports resistive/inductive loads without derating, but requires 20% current reduction for capacitive loads.
The device uses glass-passivated die construction to minimize reverse leakage (5.0mA @ 25°C, 500mA @ 125°C) and delivers low power loss via 1.1V VFM at rated half-current. Total capacitance is 300pF per element at 1MHz and 4V reverse bias.
Key Specifications

|---|---|
| VRRM | 1000 V - Maximum peak reverse voltage each diode withstands without breakdown |
| IO @ TC=50°C | 35 A - Average DC output current with case temperature held at 50°C on heatsink |
| VFM @ IF=17.5A | 1.1 V - Forward voltage drop per diode at half-rated current, defining conduction loss |
| IFSM | 400 A - Peak non-repetitive surge current tolerance for 8.3ms half-sine wave |
| RθJC | 1.2 °C/W - Thermal resistance from junction to case, critical for heatsink sizing |
| Isolation Voltage | 1500 V - Dielectric strength between case and terminals, enabling safe chassis mounting |
| CT @ 1MHz | 300 pF - Total junction capacitance per diode, affecting high-frequency EMI and snubber design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU35J | Same 35A/1000V rating, but TO-247 package with isolated tab; RθJC = 1.5°C/W | Requires insulated mounting hardware; less suited for direct-chassis mounting | Select when board-level isolation or higher creepage/clearance is required |
| ON Semiconductor GBPC3510 | Identical specs and pinout; same GBPC package; RoHS-compliant with alternate marking | No functional difference; qualified for alternate sourcing in dual-supplier programs | Use for supply chain diversification without redesign or requalification |
Compared with GBU35J, GBPC3510 offers lower thermal resistance and integrated heatsink mounting, while ON Semiconductor's GBPC3510 provides identical form-fit-function for BOM flexibility without performance trade-offs.

FAQ
What is the maximum recommended mounting torque for GBPC3510?
The datasheet specifies a maximum mounting torque of 8.0 inch-pounds for the #10 screw used to secure the GBPC3510's metal base to the heatsink. Exceeding this value risks cracking the molded plastic case or deforming the internal heatsink interface, compromising thermal performance and mechanical integrity.
Does GBPC3510 require derating for capacitive loads?
Yes - the datasheet explicitly states that average output current must be derated by 20% when the rectifier feeds a capacitive load. This accounts for higher peak currents and increased thermal stress caused by capacitor charging transients, which differ from steady-state resistive or inductive loading behavior.
What is the meaning of the "W" suffix in GBPC3510W?
The "W" suffix denotes wire lead termination instead of standard faston terminals. GBPC3510W uses tinned copper wire leads (silver-plated) compatible with through-hole soldering or crimping, whereas GBPC3510 uses stamped faston lugs for quick-connect terminals - both share identical electrical and thermal specifications.
Is GBPC3510 certified for use in safety-critical systems?
Yes - it is UL Recognized under Component Index File E94661, confirming compliance with UL 60747-4 for semiconductor devices. However, Diodes Incorporated explicitly prohibits use in life support systems without written approval, per their Life Support Notice in the datasheet.
