GBL203H

Overview

The GBL203H is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a 2 A average forward current and a 200 V repetitive peak reverse voltage rating. The device utilizes a glass passivated chip junction within a GBL through-hole package, ensuring high case dielectric strength. Electrical specifications include a maximum forward voltage of 1 V at 2 A and a typical reverse leakage current of 5 µA at rated voltage. It supports a surge peak forward current of 60 A and operates within a junction temperature range of -55°C to +150°C. The component is AEC-Q101 qualified.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High case dielectric strength suitable for PCB mounting
• Halogen-free construction compliant with IEC 61249-2-21

Applications

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

Procurement Notes

Verify the specific ordering code matches the required voltage rating and qualification level. Confirm that the 'H' suffix indicates AEC-Q101 automotive qualification as defined in the datasheet. Ensure the package type corresponds to the GBL form factor for proper board layout integration. Check RoHS compliance status against project requirements before finalizing procurement orders.

Selection Notes

Select this component when a 200 V blocking capability is required for AC-to-DC conversion circuits. The GBL package facilitates automated through-hole assembly processes. Consider the thermal resistance values for heat dissipation planning in enclosed environments. Verify that the 60 A surge current rating meets the inrush requirements of the target power supply design.

Part Context

This part belongs to the GBL201–GBL207 series of 2 A bridge rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 1000 V, with the GBL203H specifically designated for 200 V applications. The 'H' suffix distinguishes it as an AEC-Q101 qualified variant, differentiating it from the standard GBL203 version.

Replacement Considerations

The GBL203 is a parameter-equivalent alternative within the same manufacturer's lineup. Substitutions from other vendors must match the 2 A current, 200 V voltage, and GBL package dimensions.
