Overview
The Microchip Technology 1N459/TR is a general-purpose rectifier diode housed in the DO-35 (DO-204AH) axial through-hole package. It features a maximum DC reverse voltage of 200 V and an average forward current rating of 150 mA. The device exhibits a maximum forward voltage drop of 1 V at 100 mA and a low leakage current of 1 uA at rated reverse voltage. It operates within a junction temperature range of -65°C to +150°C and is supplied in tape and reel packaging.
Feature Summary
- Hermetically sealed construction with metallurgically bonded junctions for reliability
- Double plug design ensuring robust mechanical integrity
- Tightened forward voltage specification for consistent performance
Applications
- Signal processing circuits
- Computer logic interfaces
- General purpose rectification
Procurement Notes
Verify the manufacturer designation carefully, as the 1N459 series is produced by multiple vendors including onsemi and National Semiconductor. Confirm that the specific suffix matches the required JEDEC registration and electrical tolerances. Ensure the tape and reel quantity aligns with production requirements before finalizing the order.
Selection Notes
Select this component when hermetic sealing and high reliability are required for through-hole applications. The 1N459/TR offers a balance of 200 V blocking capability and moderate current handling. Compare leakage current specifications against alternative manufacturers if strict low-power standby conditions apply.
Part Context
This part belongs to the JEDEC registered 1N457A through 1N459A series of high conductance, low leakage diodes. These components utilize double plug construction and are designed for demanding environments requiring hermetic sealing. The series is widely recognized for use in critical signal and computer diode applications.
Replacement Considerations
The 1N459A is the standard JEDEC equivalent. Verify pinout compatibility and thermal characteristics when substituting with parts from other manufacturers such as onsemi or Texas Instruments.
