US1MH

Single Diodes Overview

The US1MH is a general-purpose switching diode manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage (Vrrm) of 1000 V and a maximum average forward rectified current (If) of 1 A. The device utilizes a DO-214AC (SMA) surface-mount package with two pins. Key electrical characteristics include a peak non-repetitive forward surge current (Ifsm) of 30 A, a maximum forward voltage (Vf) of 1 V, and a peak reverse current (Ir) of 5 μA. The typical peak reverse recovery time (trr) is specified as 75 ns, with an operating temperature range from -55°C to +150°C.

Single Diodes Feature Summary

• High-efficiency standard recovery rectifier design for general-purpose applications
• Robust 1000 V reverse voltage rating suitable for high-voltage circuits
• Surface-mount construction in a compact DO-214AC package

Single Diodes Applications

• General-purpose rectification in power supplies
• Freewheeling diodes in inductive load circuits
• Protection against voltage spikes in electronic systems

Single Diodes Procurement Notes

Verify the specific datasheet version for the US1MH to confirm the exact reverse recovery time specification, as sources indicate variations between 50 ns and 75 ns. Ensure the DO-214AC package dimensions match your PCB footprint requirements. Confirm that the 1000 V rating aligns with your circuit's peak inverse voltage demands before finalizing procurement.

Single Diodes Selection Notes

Select the US1MH when a high-voltage (1000 V), single-phase rectifier is required in a surface-mount format. It is appropriate for designs needing a 1 A continuous current capability with moderate switching speeds. Consider this component for space-constrained boards where through-hole alternatives are not feasible, ensuring the thermal management supports the 150°C junction temperature limit.

Single Diodes Part Context

The US1MH belongs to the US1X series of fast recovery rectifiers produced by Taiwan Semiconductor. This series is designed for general-purpose switching applications requiring reliable performance in compact packages. The DO-214AC form factor allows for automated assembly, making it suitable for high-volume manufacturing environments where board space is limited.

Single Diodes Replacement Considerations

Direct substitutes may include other 1000 V, 1 A SMA-packaged diodes such as the 1N4007 equivalent in SMD form or parts from the BYV series. Verify pinout compatibility and ensure the replacement meets the same 75 ns recovery time and 30 A surge current specifications.
