Overview
The Vishay 1N5818/54 is a Schottky Barrier Rectifier in the DO-204AL (DO-41) axial package. It features a maximum repetitive peak reverse voltage of 30 V and a maximum average forward rectified current of 1.0 A. The device exhibits a maximum instantaneous forward voltage of 0.550 V at 1.0 A DC and 0.875 V at 3.1 A DC. Maximum non-repetitive peak reverse voltage is 36 V, with a peak forward surge current capability of 25 A. Operating junction temperature ranges from -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 frequency operation suitable for inverters
Applications
- Low voltage high frequency inverters
- Freewheeling diodes
- DC-to-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix /54 against the manufacturer's official documentation to confirm the delivery mode and base quantity. Confirm RoHS compliance status as indicated by the E3 designation in related part numbers. Ensure the component matches the required electrical ratings for the target application before procurement.
Selection Notes
Select this component when a 30 V reverse voltage rating and 1 A continuous current are required. Consider the low forward voltage drop for thermal management in power applications. Verify that the DO-204AL package fits the board layout constraints. Check if higher voltage variants like the 1N5819 are needed for increased headroom.
Part Context
This part belongs to the Vishay 1N5817 through 1N5819 series of Schottky Barrier Rectifiers. The series shares identical mechanical dimensions and general characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings of 20 V, 30 V, and 40 V respectively.
Replacement Considerations
Cross-reference with other manufacturers' 1N5818 equivalents. Verify pinout compatibility and thermal resistance values. Ensure the substitute meets the same 30 V reverse voltage and 1 A forward current specifications.
FAQ
What is the maximum non-repetitive peak reverse voltage?
The maximum non-repetitive peak reverse voltage is 36 V.
What is the typical junction capacitance?
The typical junction capacitance is 110 pF at 4.0 V and 1.0 MHz.
