GBU407-K

Overview

The GBU407-K is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a maximum repetitive peak reverse voltage (VRRM) of 1000 V and an average forward current (IF) of 4 A. The device supports a surge peak forward current (IFSM) of 150 A for 8.3 ms half-sine-wave pulses. Electrical characteristics include a maximum forward voltage of 1.1 V at 4 A and 25°C, with a maximum reverse current of 500 µA at 125°C. The component operates within a junction temperature range of -55°C to +150°C and utilizes a GBU plastic package.

Feature Summary

• High case dielectric strength rated at 1500 VRMS for enhanced insulation safety
• UL Recognized File # E-326243 certification ensuring compliance with safety standards
• RoHS compliant and halogen-free construction according to IEC 61249-2-21 specifications

Applications

• Switching mode power supply (SMPS)
• Power adapters
• Lighting applications

Procurement Notes

Verify the specific ordering code GBU407-K against official Taiwan Semiconductor documentation to confirm the 1000V rating. Ensure that the procurement channel provides original manufacturer packaging, as the standard packing format is specified as tubes containing 20 units per tube. Cross-reference the date code and factory code markings on the physical components to validate authenticity and traceability.

Selection Notes

Select the GBU407-K when circuit designs require a 1000 V blocking voltage capability combined with a 4 A continuous current rating. This component is suitable for PCB mounting where high case dielectric strength is necessary. Consider the thermal resistance parameters for heat dissipation planning in enclosed environments. Verify that the operating temperature range aligns with the system's environmental constraints.

Part Context

This component belongs to the GBU404-K through GBU407-K series from Taiwan Semiconductor. The series covers voltage ratings from 400 V to 1000 V while maintaining a consistent 4 A current capacity. The GBU407-K represents the highest voltage variant in this specific lineup, sharing identical mechanical dimensions and electrical performance profiles regarding current handling and thermal characteristics with its lower-voltage counterparts.

Replacement Considerations

Compatible substitutes within the same series include GBU404-K, GBU405-K, and GBU406-K, provided the application voltage does not exceed their respective ratings. Other manufacturers offering equivalent GBU package bridge rectifiers with matching 4 A and 1000 V specifications may also serve as alternatives if pinout compatibility is confirmed.
