Overview
The Taiwan Semiconductor 1N5818 is a Schottky barrier rectifier featuring a 30 V repetitive peak reverse voltage and a 1 A average forward current. It utilizes a DO-41 axial leaded package for through-hole mounting. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30 A, a peak reverse current of 1 mA, and a maximum forward voltage of 875 mV. The device operates within a temperature range of -65°C to 125°C.
Feature Summary
- Guardring structure provides overvoltage protection
- Extremely fast switching with negligible switching losses
- Low forward voltage drop for high efficiency
- High surge current capability
Applications
- Low voltage high frequency inverters
- Free wheeling applications
- DC-to-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific manufacturer designation on the component marking, as multiple vendors produce this standard part number. Confirm RoHS compliance status if required by project specifications. Ensure the DO-41 package dimensions match the PCB footprint requirements. Check datasheets for variations in thermal resistance or surge ratings between different production batches or suppliers.
Selection Notes
Select this component for low-voltage power conversion where minimal conduction loss is critical. The Schottky technology offers superior switching speed compared to standard PN junction diodes. Verify that the 30 V reverse voltage rating exceeds the circuit's peak inverse voltage. Consider the 1 A current limit when designing for continuous load conditions.
Part Context
This component belongs to the 1N581x series of Schottky barrier rectifiers. The series includes variants with different reverse voltage ratings, such as 20 V and 40 V options. These devices are widely used in general-purpose rectification applications requiring high efficiency and fast recovery characteristics in axial packages.
Replacement Considerations
Cross-reference with other manufacturers' 1N5818 parts for pin-compatible substitution. Verify that alternative sources meet the same 30 V and 1 A specifications. Check for identical DO-41 mechanical dimensions to ensure fitment.
