Overview
The Central Semiconductor Corp 1N5819 BK TIN/LEAD is a 40 V, 1 A axial Power Schottky Rectifier. Packaged in DO-41, it is designed for low voltage, high frequency inverters, free wheeling, polarity protection, and small battery chargers. Key electrical characteristics include very small conduction losses, negligible switching losses, extremely fast switching speeds, and a low forward voltage drop. The device also features specified avalanche capability.
Feature Summary
- Schottky barrier construction with Guard Ring die design for transient protection
- Plastic material with UL flammability classification rating 94V-0
- High surge current capability combined with low forward voltage drop
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 tin/lead lead finish against current RoHS compliance requirements if restricted substances are mandated for the target application. Confirm that the DO-41 axial package dimensions match the PCB footprint constraints. Ensure the 40 V reverse voltage rating provides sufficient margin for the peak inverse voltage present in the circuit design.
Selection Notes
Select this component when low forward voltage drop and fast switching are critical for efficiency in power conversion stages. The DO-41 through-hole package is suitable for designs requiring robust mechanical mounting. Verify that the 1 A continuous current rating meets the load requirements without exceeding thermal limits.
Part Context
This part belongs to the 1N5817-1N5819 series of 1.0A Schottky Barrier Rectifiers manufactured by Central Semiconductor Corp. These devices utilize silicon technology and are housed in plastic DO-41 packages. The series is engineered for applications demanding high efficiency and reliability in rectification tasks.
Replacement Considerations
Cross-reference with other manufacturers offering 1N5819 equivalents in DO-41 packages. Verify matching specifications for 40 V reverse voltage, 1 A forward current, and similar forward voltage drops before substitution.
