Overview
The STMicroelectronics 1N5819RL is a Schottky rectifier with a 40 V repetitive peak reverse voltage and 1 A average forward current. It features a maximum forward voltage of 0.85 V at 1 A and a reverse leakage current of 500 µA at 40 V. The device supports a non-repetitive peak surge current of 25 A and operates within a junction temperature range of -65°C to 150°C. Packaged in the DO-41 axial leaded format, it is designed for low voltage, high frequency applications.
Feature Summary
- Schottky barrier technology providing very small conduction losses and negligible switching losses
- Extremely fast switching capability suitable for high frequency inverters
- Low forward voltage drop characteristics
- Specified avalanche capability
Applications
- Switch Mode Power Supplies
- High frequency DC to DC converters

Procurement Notes
Verify component status as sources indicate this specific part number may be obsolete or inactive. Confirm availability through authorized distributors and check for manufacturer-recommended replacements such as the STPS1L40ZF. Ensure compliance with RoHS3 specifications and validate package details against current procurement requirements before ordering.
Selection Notes
Select this component for low voltage, high frequency rectification tasks requiring fast switching speeds. The DO-41 package suits through-hole mounting needs. Consider the 40 V rating and 1 A current capacity when designing power supply stages. Evaluate thermal management capabilities given the 150°C maximum junction temperature limit for reliable operation in demanding environments.
Part Context
This device belongs to the 1N5819 series of axial power Schottky rectifiers manufactured by STMicroelectronics. It utilizes the standard DO-41 (DO-204AL) axial leaded package. The product is categorized under discrete semiconductor diodes and rectifiers, specifically designed for general-purpose rectification in electronic circuits where low forward voltage and fast recovery are critical performance factors.
Replacement Considerations
Publicly confirmed substitutes include STPS1L40ZF from STMicroelectronics and 1N5818-T from Diodes Incorporated. Verify electrical parameter compatibility and package dimensions before implementation.
