1N5819W

Overview

The 1N5819W is a Schottky barrier rectifier manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It features an average forward current of 1 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes a metal silicon junction with majority carrier conduction to achieve low power loss and high efficiency. Key electrical characteristics include a low forward voltage drop, high surge capability, and negligible switching losses. Packaged in DO-204AL (DO-41), it operates within a temperature range of -65 °C to +125 °C.

Feature Summary

Metal silicon junction construction enabling majority carrier conduction for minimal power loss
Guardring design providing protection against overvoltage conditions
Extremely fast switching speeds suitable for high frequency applications

Applications

Low voltage, high frequency inverters
Free wheeling diode circuits
Polarity protection systems
Switch mode power supplies

Procurement Notes

Verify the specific manufacturer designation as Shenzhen Slkormicro Semicon Co., Ltd. differs from common industry sources listing STMicroelectronics or onsemi. Confirm RoHS compliance status and package dimensions against the official datasheet before integration. Ensure the component meets all environmental and electrical specifications required for the target application.

Selection Notes

Select this component for designs requiring efficient rectification at low voltages and high frequencies. The DO-41 axial package facilitates through-hole mounting. Consider the 40 V reverse voltage rating and 1 A current capacity when sizing the circuit. Evaluate thermal management requirements given the operating temperature limits and forward voltage characteristics.

Part Context

This part belongs to the standard 1N58xx series of Schottky barrier rectifiers. These devices are widely recognized for their superior performance compared to standard silicon rectifiers in terms of speed and forward voltage drop. The 1N5819 variant specifically targets 40 V applications within this family.
