Overview
The Vishay VS-8EWS16SLHM3 is a high-voltage surface mount input rectifier diode rated for 1600 V reverse voltage and 8 A average forward current. It utilizes a standard recovery speed exceeding 500 ns with a maximum forward voltage of 1.1 V at 8 A. The device features a low leakage current of 50 µA at full reverse voltage and operates within a junction temperature range of -40°C to 150°C. Packaged in a TO-252AA (DPAK) case, it meets AEC-Q101 automotive qualification standards.
Feature Summary
- High voltage capability up to 1600 V for robust input rectification
- Automotive grade reliability certified under AEC-Q101 standards
- Surface mount construction in a compact DPAK package for efficient PCB integration
Applications
- Automotive power supply circuits
- High voltage DC-DC converter inputs
- Industrial rectification applications requiring high surge withstand
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging variations. Ensure the component matches the required automotive qualification level if used in safety-critical systems. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring high reverse voltage blocking capabilities in a surface mount form factor. The standard recovery characteristic makes it suitable for general-purpose rectification where fast switching is not critical. Consider the thermal performance of the DPAK package and ensure adequate copper area on the PCB for heat dissipation during continuous 8 A operation.
Part Context
This diode belongs to Vishay's 8EWS16 series of high voltage surface mount rectifiers. The series is designed to replace traditional through-hole packages in modern electronics while maintaining high voltage ratings. It serves as a key component in power management stages where space constraints and high voltage isolation are primary design drivers.
Replacement Considerations
Direct substitutes include other Vishay parts from the 8EWS16 series with compatible pinouts and electrical ratings. Verify that any replacement maintains the same AEC-Q101 certification if automotive compliance is mandatory. Check for equivalent forward voltage and reverse leakage specifications to ensure circuit performance remains unchanged.
