Overview
The Comchip Technology 1N5819-G is a single silicon Schottky barrier rectifier housed in the DO-41 through-hole package. It supports a maximum average forward current of 1 A and a repetitive peak reverse voltage of 40 V. The device exhibits a typical forward voltage drop of 600 mV at rated current and handles a non-repetitive surge current of 25 A. Operating temperatures range from -55 °C to +150 °C junction temperature, with a specified reverse leakage current of 1 mA.
Feature Summary
- Utilizes Schottky barrier technology for low forward voltage drop and fast switching characteristics
- Designed for high efficiency with negligible switching losses and small conduction losses
- Features avalanche capability specification for enhanced reliability under transient conditions
Applications
- Switch Mode Power Supplies (SMPS)
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling diodes
- Polarity protection circuits
Procurement Notes
Verify the specific suffix 'G' against the manufacturer's datasheet to confirm compliance with RoHS directives and material composition requirements. Ensure the DO-41 axial lead package matches the target PCB footprint and mounting constraints. Confirm that the 1 A current rating and 40 V breakdown voltage align with the circuit design specifications before finalizing procurement orders.
Selection Notes
Select this component when low forward voltage drop and high switching speed are critical for system efficiency. The DO-41 package suits through-hole assembly processes requiring robust mechanical stability. Verify thermal management capabilities given the 150 °C maximum junction temperature rating. Consider the 1 mA reverse leakage current impact on sensitive low-power applications compared to alternatives with lower leakage specifications.
Part Context
This part belongs to the standard 1N5819 series of axial power Schottky rectifiers. While generic 1N5819 devices are widely available from various manufacturers, the Comchip Technology variant specifies particular electrical tolerances and packaging standards. The 'G' suffix typically denotes specific manufacturing or environmental compliance attributes distinct from the base model number.
Replacement Considerations
Generic 1N5819 equivalents from other manufacturers may serve as substitutes if electrical parameters match exactly. Verify package compatibility and pinout alignment. Check for differences in reverse leakage current and forward voltage tolerance which may affect circuit performance. Ensure replacement parts meet the same thermal and voltage ratings.
