Overview
The Central Semiconductor Corp 1N5818 TR PBFREE is an axial power Schottky rectifier designed for switch mode power supplies and high-frequency DC to DC converters. Packaged in a DO-41 housing, this device operates with a maximum average forward current of 1 A and a maximum repetitive peak reverse voltage of 30 V. It features very small conduction losses, negligible switching losses, extremely fast switching speeds, and a low forward voltage drop. The component also specifies avalanche capability.
Feature Summary
- Extremely fast switching characteristics
- Low forward voltage drop
- Avalanche capability specified
Applications
- Switch Mode Power Supplies
- High frequency DC to DC converters
- Low voltage high frequency inverters
- Free wheeling applications
- Polarity protection circuits
- Small battery chargers
Procurement Notes
Verify the specific manufacturer source for the 'TR' suffix designation, as standard datasheets for the 1N5818 series typically list it without tape-and-reel identifiers. Confirm RoHS compliance status directly with the supplier documentation. Ensure the DO-41 axial package matches the required PCB footprint. Validate that the 1 A current rating and 30 V reverse voltage meet the circuit design requirements before finalizing procurement.
Selection Notes
Select this component when low forward voltage drop and fast switching are critical for efficiency in power conversion circuits. The DO-41 axial package is suitable for through-hole mounting applications requiring robust mechanical stability. Consider the specified avalanche capability if the circuit may experience transient overvoltage conditions. Ensure the thermal management strategy supports the power dissipation limits inherent to the 1 A continuous current rating.
Part Context
The 1N5818 is a widely recognized silicon Schottky barrier rectifier. Central Semiconductor offers this part as a discrete semiconductor component. The device belongs to the general class of signal diodes and rectifiers used for converting AC to DC or protecting circuits from reverse polarity. Its axial leaded construction distinguishes it from surface-mount alternatives in the same voltage and current category.
Replacement Considerations
Equivalent parts include the 1N5818-T manufactured by DiodesZetex. Other generic replacements within the 1N5818 series from various manufacturers may be compatible provided they adhere to the same DO-41 package dimensions and electrical specifications.
