Overview
The GBU4K-T is a single-phase bridge rectifier manufactured by Diotec Semiconductor, housed in the GBU package. It features a maximum average forward rectified current of 4 A and a peak repetitive reverse voltage of 800 V. The device utilizes silicon planar technology with glass passivation for junction protection. Key electrical parameters include a maximum non-repetitive peak forward surge current of 150 A at 60 Hz, a maximum DC blocking voltage of 800 V, and a maximum RMS voltage of 560 V. The component supports a wide operating junction temperature range from -55°C to +175°C.
Feature Summary
- Glass passivated junctions provide mechanical strength and resistance to moisture-induced corrosion.
- High thermal performance capability allows operation up to a maximum junction temperature of 175°C.
- Molded plastic case ensures compliance with UL flammability classification 94V-0 standards.
Applications
- AC-DC power supply circuits
- Battery chargers
- Inverter circuits
Procurement Notes
Verify the specific ordering code suffix against official Diotec Semiconductor documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and REACH SVHC declarations directly through authorized distributors or manufacturer datasheets prior to procurement.
Selection Notes
Select this component when an 800 V reverse voltage rating and 4 A continuous current capacity are required within a GBU surface-mount or through-hole form factor. Ensure the application's thermal management strategy accommodates the specified junction temperature limits and power dissipation characteristics under expected load conditions.
Part Context
This part belongs to the GBU series of single-phase bridge rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings and current capacities within the same standardized package outline, facilitating design flexibility while maintaining consistent mounting dimensions and thermal profiles across different product selections.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains identical pinout configuration, voltage ratings, and current capabilities to guarantee functional compatibility without circuit modification.
