1N459ATR

Single Diodes Overview

The onsemi 1N459ATR is a small signal switching diode designed for high conductance and low leakage applications. It features a single configuration housed in a DO-35 through-hole package. The device supports a peak repetitive reverse voltage of 200 V and a maximum forward current of 500 mA. It withstands a maximum surge current of 4 A with a forward voltage drop of 1 V at rated current. Reverse leakage current is limited to 25 nA. The component operates within a temperature range from -65 °C to +175 °C.

Single Diodes Feature Summary

• High conductance characteristics for efficient signal switching
• Low leakage performance suitable for precision circuits
• Extended thermal stability up to 175 °C

Single Diodes Applications

• General purpose rectification
• Signal switching circuits
• Clamping and protection applications

Single Diodes Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details, as variations exist between bulk and reel formats. Ensure compliance with RoHS and REACH requirements by checking the latest product compliance statements provided by onsemi before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a through-hole small signal diode with 200 V reverse voltage capability is required. The DO-35 package suits standard PCB layouts. Consider the 175 °C maximum operating temperature for high-thermal environments. Verify that the 500 mA continuous current rating meets the circuit's steady-state demands.

Single Diodes Part Context

This part belongs to the 1N459A series of general-purpose diodes manufactured by onsemi. It shares the same electrical specifications as the non-ATR variant but differs in packaging format. The series is categorized under small signal switching diodes and rectifiers within the broader semiconductor portfolio.

Single Diodes Replacement Considerations

The 1N459 (bulk package) serves as a functional equivalent with identical electrical parameters. Other 1N459A variants may be compatible if package type differences are acceptable.
