Overview
The 1N5817WS is a Schottky rectifier manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes a WS (SOD-123) surface-mount package with two pins. Key electrical parameters include a maximum DC reverse leakage current of 1 mA at the rated voltage and a maximum forward voltage drop of 450 mV at 1 A. The component operates within a junction temperature range of -65°C to +125°C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Surface-mount SOD-123 (WS) package design
- High efficiency switching capability
Applications
- DC-DC converter freewheeling diodes
- Power supply output rectification
- Reverse polarity protection circuits
Procurement Notes
Verify the manufacturer designation on the component marking, as the 1N5817WS part number is widely used across multiple semiconductor producers. Confirm that the specific batch corresponds to Shenzhen Slkormicro Semicon Co., Ltd. specifications rather than other vendors offering identical electrical ratings in the same package. Ensure compliance with required environmental standards before integration.
Selection Notes
Select this component when a surface-mount Schottky rectifier is required for low-voltage, high-efficiency applications. The 20 V rating suits low-voltage power rails where minimizing conduction loss is critical. Compare thermal resistance values against available alternatives to ensure adequate heat dissipation within the compact SOD-123 footprint for the intended load conditions.
Part Context
This component belongs to the standard 1N58xx series of Schottky rectifiers, adapted for surface-mount technology. While traditional versions utilize axial DO-41 packages, the WS variant provides a compact alternative suitable for automated PCB assembly. It serves as a direct functional equivalent to through-hole counterparts in modern miniaturized electronic designs requiring robust rectification.
Replacement Considerations
Direct substitutes include the 1N5817W from Vishay or STPS1L20 from STMicroelectronics. Verify pinout compatibility and thermal characteristics when replacing components from different manufacturers to ensure circuit performance remains within specified limits.
