1N647/TR

Overview

The 1N647/TR is a general-purpose rectifier diode manufactured by Microchip Technology. It utilizes a DO-204AH (DO-35) axial leaded package for through-hole mounting. The device features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 400 mA. It operates within a temperature range of -55°C to +175°C and is supplied in tape and reel packaging.

Feature Summary

High thermal stability with extended operating temperature limits
Robust construction suitable for clipping and steering applications
Standard axial leaded form factor for reliable through-hole integration

Applications

General purpose rectification in power supply circuits
Signal clipping and waveform shaping
Current steering in electronic control systems

Procurement Notes

Verify the specific suffix against official Microchip documentation, as variants such as 1N647-1 or 1N647-1E3 exist with distinct specifications. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the ordering part number matches the required voltage and current ratings for the target application circuit design.

Selection Notes

Select this component when a standard recovery diode with 400 V blocking capability is required. The DO-35 package offers a compact solution for space-constrained through-hole designs. Evaluate the 400 mA current rating against peak load requirements to ensure adequate margin for thermal management and long-term reliability in the intended operational environment.

Part Context

This component belongs to the legacy 1N series rectifier family, now produced under Microchip Technology following industry consolidations. It serves as a high-performance alternative to smaller signal diodes where higher current handling is necessary. The product maintains compatibility with traditional through-hole manufacturing processes while offering improved thermal characteristics over basic equivalents.
