MNS1N5819UR-1/TR

Single Diodes Overview

The MNS1N5819UR-1/TR is a Schottky rectifying diode manufactured by Microchip Technology. It features a peak repetitive reverse voltage (Vrrm) of 45 V and a maximum continuous forward current (If) of 1 A. The device is housed in a surface-mount DO-213AB (MELF, LL41) package with two pins. Key electrical parameters include a peak non-repetitive forward surge current (Ifsm) of 25 A, a maximum forward voltage (Vf) of 0.85 V, and a peak reverse current (Ir) of 500 μA. The junction capacitance is specified at 70 pF. The component operates within a temperature range from -65°C to +150°C.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and high switching efficiency.
• Designed for surface-mount assembly using the compact DO-213AB MELF package.
• Capable of handling high surge currents up to 25 A for transient protection.

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Free-wheeling diodes in inductive load switching applications
• Clamping diodes in digital and analog signal processing

Single Diodes Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration when ordering. Confirm that the DO-213AB MELF footprint matches your PCB design constraints. Ensure thermal management strategies account for the 150°C maximum junction temperature rating during operation. Cross-reference datasheets for any recent product change notifications or compliance updates.

Single Diodes Selection Notes

Select this component when a surface-mount Schottky diode with 45 V blocking capability and 1 A continuous current rating is required. The DO-213AB package offers a compact alternative to through-hole options like DO-41. Consider the low forward voltage and fast recovery characteristics for efficiency-critical designs. Verify compatibility with automated pick-and-place equipment due to the small form factor.

Single Diodes Part Context

This part belongs to the 1N5819 series family, adapted for surface-mount technology. While traditional 1N5819 diodes are often available in axial leaded packages, the MNS1N5819UR-1/TR variant provides equivalent electrical performance in a MELF case suitable for modern SMD manufacturing processes. It serves as a direct functional replacement for legacy through-hole versions in space-constrained designs.

Single Diodes Replacement Considerations

Direct equivalents include other 45V 1A Schottky diodes in DO-213AB packages. Verify pinout and thermal resistance specifications when substituting with parts from different manufacturers to ensure circuit reliability.
