1A5

Overview

The SMC Diode Solutions 1A5 is a general-purpose rectifier diode designed for through-hole mounting in the R-1 axial package. It features a maximum DC reverse voltage (Vr) of 600 V and an average forward rectified current (Io) of 1 A. The device exhibits a maximum forward voltage drop (Vf) of 1.3 V at 1 A and a low reverse leakage current of 5 µA at 600 V. Operating within a junction temperature range of -55°C to 150°C, it offers a typical reverse recovery time (trr) of 20 ns and a junction capacitance of 15 pF at 4 V and 1 MHz.

Feature Summary

• High voltage blocking capability up to 600 V with 1 A continuous current handling
• Fast switching performance characterized by a 20 ns reverse recovery time
• Robust thermal stability supporting operation up to 150°C junction temperature

Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in inductive load protection
• DC-AC conversion stages in standard electronic equipment

Procurement Notes

Verify the component authenticity against official SMC Diode Solutions documentation before integration. Confirm that the R-1 axial package dimensions match the target PCB layout requirements. Ensure the selected supplier provides traceable manufacturing data consistent with the RoHS3 compliance status specified in the datasheet. Cross-reference the specific lot codes if required for quality assurance protocols.

Selection Notes

Select this component when a 600 V rating is necessary for high-voltage rectification applications requiring 1 A capacity. The fast recovery characteristic makes it suitable for higher frequency switching environments compared to standard slow-recovery diodes. Consider the axial leaded form factor for manual assembly or specific mechanical constraints where surface mount options are unsuitable.
