Product details
Overview
GBPC3506 from Diodes Incorporated is a 35A glass passivated single-phase bridge rectifier with 600V peak repetitive reverse voltage (VRRM), 400A non-repetitive surge current rating (IFSM), and 1.1V forward voltage per element at 17.5A - used in AC/DC power supplies for industrial motor drives, UPS systems, and welding equipment.
For engineers reviewing the GBPC3506 datasheet, GBPC3506 pinout, GBPC3506 application, or GBPC3506 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 derating behavior under capacitive loads (20% current reduction).
Technical Context
This 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.
Each diode leg exhibits 300pF typical junction capacitance at 1MHz/4V reverse bias and 5.0mA peak reverse leakage at 25°C - critical for EMI-sensitive switching power supply front-ends where low IR and CT reduce conduction loss and high-frequency noise coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum peak reverse voltage each diode withstands without breakdown; defines safe AC input range up to 420V RMS. |
| IO @ TC=50°C | 35 A - average DC output current deliverable when case temperature is held at 50°C using heatsink; sets continuous power handling. |
| IFSM (8.3ms) | 400 A - surge current tolerance during line transients or startup; enables robust operation in motor-start or capacitor-charging circuits. |
| VFM @ IF=17.5A | 1.1 V - forward voltage drop per diode at half-rated current; determines conduction loss (≈3.9W total for full-wave rectification). |
| RθJC | 1.2 °C/W - thermal resistance from junction to case; requires minimum heatsink interface area and mounting pressure to maintain Tj ≤150°C. |
| IR @ VR=600V | 5.0 mA - reverse leakage at rated blocking voltage and 25°C; impacts standby power loss and voltage hold-up in high-impedance circuits. |
| Isolation Voltage | 1500 V - dielectric strength between case and terminals; satisfies reinforced insulation requirements for Class I mains-connected equipment. |
Pinout & Package
GBPC3506 uses the standard GBPC through-hole package: 4-terminal configuration with two AC inputs (A1, A2), one positive DC output (+), and one negative DC output (–). Mounting is via central #10 screw hole (5.08–5.59mm diameter) on metal baseplate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / A2 | AC Input Terminals | Accept full-wave AC input; symmetrical layout allows either terminal as live or neutral entry point. |
| (+) | Positive DC Output | Common anode node of two series-connected diodes; connects to bulk capacitor positive rail. |
| (–) | Negative DC Output | Common cathode node of two series-connected diodes; serves as system ground reference or return path. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Enables stable reverse characteristics and long-term reliability under humidity and thermal cycling stress. |
| Metal base with internal heatsink | Provides low-thermal-resistance path to external heatsink; eliminates need for separate mounting hardware beyond screw. |
| UL Recognized Component (E94661) | Validates compliance with UL 60950-1/IEC 62368-1 for end-equipment safety certification. |
| Lead-free, RoHS-compliant finish | Meets EU Directive 2011/65/EU with exemptions for high-temp solder; compatible with lead-free reflow and wave processes. |
| 1500V case-to-terminal isolation | Supports double-insulation design in medical and industrial AC-input power supplies without additional barriers. |
Applications
| Industrial Motor Drives | Uninterruptible Power Supplies (UPS) |
|---|---|
Use Scenario: Rectifying 3-phase or split-phase AC input before DC bus filtering and inverter stage. IC Role / Device Role / Timing Role: Primary AC/DC conversion device; handles continuous 35A load and absorbs line surges up to 400A. Use Value: Low 1.1V VFM minimizes heat generation at high current, while 1.2°C/W RθJC enables compact heatsink integration. | Use Scenario: Converting utility AC to DC for battery charging and inverter input during normal operation. IC Role / Device Role / Timing Role: Front-end rectifier in offline SMPS topology; must sustain surge currents during generator switchover events. Use Value: 400A IFSM rating ensures survival during 10-cycle line faults; 1500V isolation meets UPS safety standards. |
| Welding Equipment Power Supplies | AC-DC Industrial Lighting Ballasts |
Use Scenario: High-current DC source for arc initiation and maintenance in stick/TIG welders. IC Role / Device Role / Timing Role: Bulk rectifier feeding large electrolytic banks; subjected to repeated short-duration overloads. Use Value: Glass passivation prevents parameter drift under repeated thermal shock; metal base dissipates transient energy efficiently. | Use Scenario: Rectifying 230V AC mains to feed high-frequency inverters driving HID or LED lamps. IC Role / Device Role / Timing Role: Input-stage bridge in electronic ballast; operates continuously at elevated ambient temperatures. Use Value: –65°C to +150°C operating range ensures stability in enclosed, thermally constrained fixtures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU35J | Same 35A/600V rating but TO-247 package; higher RθJC (1.5°C/W); no integrated heatsink base. | Requires external heatsink and insulating hardware; less suitable for direct-mount chassis designs. | Prefer GBPC3506 when mechanical integration, isolation, or thermal simplicity is prioritized. |
| ON Semiconductor GBPC3506 | Identical electrical specs and pinout; differs only in branding and packaging documentation (no functional difference). | No application impact; fully interchangeable in BOMs and layouts. | Select based on distributor availability and traceability requirements; both meet same JEDEC and UL standards. |
Compared with GBU35J, GBPC3506 offers lower thermal resistance and built-in isolation, reducing system-level heatsinking complexity; versus ON's identical part, it provides equivalent performance with Diodes Incorporated's supply chain continuity and lifecycle management.

FAQ
What is the maximum allowable mounting torque for GBPC3506?
The maximum mounting torque for GBPC3506 is 8.0 inch-pounds. Exceeding this value risks cracking the molded plastic case or deforming the internal metal baseplate, which compromises thermal contact and mechanical integrity. Use a calibrated torque screwdriver and verify flatness of the mounting surface before installation.
Does GBPC3506 require derating for capacitive loads?
Yes - for capacitive loads, the average output current must be derated by 20% from the rated 35A. This accounts for high inrush currents that increase junction temperature beyond steady-state limits. Derating ensures reliable operation and avoids premature failure due to thermal runaway during capacitor charging cycles.
Can GBPC3506 be used in surface-mount designs?
No - GBPC3506 is a through-hole device designed for screw-mounting to a heatsink or chassis. Its GBPC package lacks SMT-compatible terminations or thermal pad geometry. For surface-mount alternatives, consider Diodes Incorporated's GBJ series or Vishay's KBU series with appropriate footprint and thermal vias.
What is the moisture sensitivity level (MSL) of GBPC3506?
GBPC3506 has a moisture sensitivity level of MSL 1 per J-STD-020C, meaning it is not sensitive to moisture and does not require dry-packaging or floor-life controls prior to assembly. This simplifies inventory handling and eliminates bake-out steps during PCB manufacturing.
