Overview
The 1N6676/TR is a small-signal Schottky rectifier manufactured by Microchip Technology. It features a single element silicon construction housed in a hermetically sealed DO-35 (DO-204AH) axial leaded package. The device is rated for a maximum repetitive peak reverse voltage of 30V and an average forward rectified current of 0.2A. It operates within a junction temperature range of -65°C to +125°C, ensuring reliability in demanding environments.
Feature Summary
- Hermetically sealed DO-35 glass passivated package for environmental protection
- Low forward voltage drop characteristic typical of Schottky technology
- High surge current capability for transient load handling
Applications
- DC-DC converter input/output rectification
- Power supply freewheeling diodes
- Reverse polarity protection circuits
Procurement Notes
Verify the specific suffix /TR indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status with the manufacturer as historical data may vary. Ensure the DO-35 axial lead form factor matches the PCB footprint requirements. Validate that the 30V rating meets the circuit's peak inverse voltage demands under all operating conditions.
Selection Notes
Select this component for applications requiring low forward voltage drop and fast switching speeds in a through-hole axial package. Compare against standard PN junction diodes where lower power dissipation is critical. Ensure the 0.2A current rating accommodates the maximum continuous load current plus safety margins. Verify thermal management capabilities for the intended ambient temperature range.
Part Context
This part belongs to Microchip's legacy discrete diode portfolio, originally derived from Microsemi specifications. It serves as a robust solution for general-purpose rectification in industrial and commercial electronics. The DO-35 package provides a standardized mounting profile compatible with automated insertion equipment.
Replacement Considerations
Direct substitutes include other 30V 200mA Schottky diodes in DO-35 packages such as the 1N5819 series equivalents, though electrical characteristics like forward voltage must be compared. Verify pinout compatibility and thermal resistance values before substitution.
