Overview
The Central Semiconductor Corp 1N5819 TR PBFREE is a Schottky barrier rectifier diode designed for surface-mount applications. It features a maximum continuous forward current of 1 A and a repetitive peak reverse voltage of 40 V. The device utilizes a DO-201AD (DO-41) axial leaded package, providing low forward voltage drop and high switching efficiency. Key electrical parameters include a maximum non-repetitive peak forward surge current of 35 A and a maximum DC reverse leakage current of 10 mA at rated voltage. It operates within a junction temperature range of -65°C to +175°C.
Feature Summary
- Schottky barrier construction for low forward voltage drop and minimal power loss
- High thermal stability with extended operating junction temperature range
- Lead-free packaging compliant with RoHS directives
Applications
- General-purpose rectification in low-voltage power supplies
- Free-wheeling diodes in inductive load circuits
- Clamping diodes in protection circuits
Procurement Notes
Verify the specific suffix 'TR' against the manufacturer's official datasheet for the 1N5819 series. Standard 1N5819 devices are typically axial leaded; confirm if this variant denotes a specific tape-and-reel processing method or if it represents a standard bulk/box shipment designation. Ensure the component matches the DO-201AD physical dimensions and terminal configuration required by the design.
Selection Notes
Select this component for designs requiring robust reverse blocking capability up to 40 V with moderate current handling. The Schottky technology offers superior speed compared to standard PN junction rectifiers, making it suitable for higher frequency applications where efficiency is critical. Verify that the package style aligns with the PCB footprint and assembly process capabilities.
Part Context
This part belongs to the widely recognized 1N58xx series of Schottky rectifiers manufactured by Central Semiconductor Corp. These devices are established components in discrete semiconductor catalogs, known for reliability in consumer electronics and industrial control systems. The 'PBFREE' designation indicates compliance with environmental standards regarding restricted hazardous substances.
Replacement Considerations
Direct replacements include the STMicroelectronics 1N5819 and Vishay VS-1N5819TR-M3. When substituting, verify that the alternative maintains the same DO-201AD package outline and meets the 1 A / 40 V rating requirements.
