Overview
The onsemi GBPC3508W is a single-phase glass passivated bridge rectifier designed for high-current applications. It features an average forward current (If) of 35A and a maximum repetitive peak reverse voltage (Vrrm) of 800V. The device utilizes a GBPC package with four pins, supporting through-hole mounting. Key electrical parameters include a peak forward voltage (Vf) of 1.1V at rated current and a peak non-repetitive forward surge current (Ifsm) of 400A. The component operates within a temperature range of -55°C to +150°C junction temperature.
Feature Summary
- Glass passivated die construction ensures stable performance and low reverse leakage current.
- Integrally molded heatsink design facilitates efficient thermal dissipation for high-power operations.
- Terminals are solderable in accordance with MIL-STD-202, method 208 standards.
Applications
- General purpose power supply circuits requiring robust rectification.
- Industrial equipment power modules.
- Military and aerospace electronic systems.
Procurement Notes
Verify the specific manufacturer source, as the GBPC3508W designation is utilized by multiple vendors including Diodes Incorporated and Panjit. Confirm that the received component matches the onsemi datasheet specifications regarding pinout and thermal resistance. Ensure compliance with required environmental certifications such as RoHS before integration into final assemblies.
Selection Notes
Select this component when an 800V blocking capability is required alongside a continuous 35A load. The GBPC package offers a balance between current handling and physical footprint. Consider the 1.1V forward voltage drop for efficiency calculations in low-voltage output stages. Verify thermal management requirements given the 83.3W power dissipation rating.
Part Context
This part belongs to the GBPC35 series of bridge rectifiers from onsemi. The series provides various voltage ratings from 50V to 1000V while maintaining a consistent 35A current capacity. The 'W' suffix typically denotes specific packaging or lead-free processing variations within the product line.
Replacement Considerations
Direct substitutes with identical electrical characteristics include VS-GBPC3508W from Vishay. Other manufacturers such as Diodes Incorporated also produce equivalent parts under the same model number. Ensure mechanical dimensions and terminal configurations match during replacement.
