Overview
The BYW74-L36 is a silicon planar ultra-fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration housed in an SOD-64 surface-mount package designed for through-hole mounting compatibility. The component supports a continuous forward current of 4.0 A and withstands a repetitive peak reverse voltage of 200 V. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current, a low reverse leakage current of 10 µA, and a fast recovery time of 35 ns. It handles a maximum surge current of 70 A and operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Ultra-fast recovery performance with a 35 ns switching speed suitable for high-frequency applications
- High thermal stability allowing operation up to a junction temperature of +175 °C
- Robust surge current handling capability of 70 A for transient protection
- Low forward voltage drop of 1.1 V to minimize conduction losses
Applications
- High-frequency power supply rectification
- Free-wheeling diodes in DC-DC converters
- Snubber circuits in switching mode power supplies
- General purpose rectification in industrial electronics
Procurement Notes
Verify the specific suffix '-L36' against the official Vishay datasheet to confirm packaging details and compliance status. Ensure the ordering part number matches the required SOD-64 package type. Confirm RoHS compliance requirements with the manufacturer's latest documentation before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring fast switching speeds and high reliability in compact form factors. The SOD-64 package offers space efficiency while maintaining high current capabilities. Consider the 200 V reverse voltage rating when designing for mains-derived or intermediate bus voltages. Evaluate thermal management needs given the 175 °C maximum junction temperature rating.
Part Context
The BYW74 series represents Vishay's line of silicon planar ultra-fast recovery rectifiers. These devices are engineered for high-efficiency power conversion applications where rapid switching and low reverse recovery charge are critical. The BYW74-L36 variant specifically denotes the 200 V rating within this family, utilizing advanced silicon technology to achieve superior performance compared to standard recovery diodes.
Replacement Considerations
Consult Vishay's official cross-reference guides for verified substitutes. Potential alternatives may include other ultra-fast recovery rectifiers from Vishay or competitors with matching 4 A current, 200 V voltage, and SOD-64 package constraints. Verify pinout compatibility and thermal characteristics before substitution.
