ST1J

Single Diodes Overview

The Diotec Semiconductor ST1J is a standard recovery rectifier diode designed for surface-mount applications. It features a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage rating of 600 V. The device utilizes an SMAF (DO-221AC) package, offering a low-profile form factor suitable for compact circuit designs. Electrical characteristics include a maximum forward voltage of less than 1.1 V at 1 A and a typical reverse recovery time of approximately 1500 ns. The component supports a junction temperature range from -50°C to +150°C and can withstand surge currents up to 30 A.

Single Diodes Feature Summary

• Standard recovery rectification with low forward voltage drop
• Low profile SMAF surface-mount packaging
• High thermal stability with extended junction temperature range

Single Diodes Applications

• 50/60 Hz mains rectification
• General-purpose power supplies
• Circuit polarity protection

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. Standard commercial grade parts lack automotive qualifications. Suffixes such as -Q or -AQ indicate AEC-Q101 compliance or qualification respectively. Confirm that the required variant matches the intended reliability standards before finalizing procurement orders.

Single Diodes Selection Notes

Select the ST1J for circuits requiring 600 V blocking capability in a compact surface-mount footprint. Ensure the design accommodates the typical 1500 ns reverse recovery time, which distinguishes it from ultrafast variants. Verify thermal management requirements against the specified thermal resistance values for the target operating environment.

Single Diodes Part Context

The ST1J belongs to the ST1A through ST1M series of standard recovery SMD rectifiers manufactured by Diotec Semiconductor. This family provides various voltage ratings from 50 V to 1000 V within the same SMAF package outline. The series is engineered for general commercial and industrial applications requiring reliable single-phase rectification.
