HER103G-K

Single Diodes Overview

The HER103G-K is a high-efficiency fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a single die configuration housed in the DO-204AL (DO-41) through-hole package. The device supports an average forward current of 1 A and offers a repetitive peak reverse voltage rating of 200 V. Key electrical specifications include a maximum forward voltage of 1.0 V at 1 A, a surge peak forward current capability of 30 A, and a typical reverse recovery time of 50 ns. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Glass passivated chip junction for enhanced reliability
• High current capability with low forward voltage drop
• Halogen-free construction compliant with IEC 61249-2-21
• Pure tin plated leads solderable per J-STD-002

Single Diodes Applications

• DC to DC converter circuits
• Switching mode power supplies and inverters
• Freewheeling diode applications

Single Diodes Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The standard tape and reel packaging contains 5,000 units, while the A0G ammo box variant holds 3,000 units. Confirm that the requested part number matches the exact voltage rating required for the target application circuit design.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating is required alongside a 1 A continuous forward current capacity. The 50 ns reverse recovery time makes it suitable for general-purpose high-frequency switching applications. Ensure the thermal management design accounts for the specified junction-to-ambient thermal resistance values under expected load conditions.

Single Diodes Part Context

This component belongs to the HER1xG-K series, which encompasses devices ranging from 50 V to 1000 V reverse voltage ratings. All members of this family share identical mechanical dimensions and electrical characteristics except for their specific voltage breakdown limits. The 'K' suffix denotes the specific packaging configuration provided by the manufacturer.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-41 packaged fast recovery rectifiers rated at 1 A and 200 V. Verify that substitute parts meet or exceed the 50 ns reverse recovery time and 1.0 V forward voltage specifications to maintain circuit performance integrity.
