Overview
The BY500-800-E3/73 is a silicon rectifier diode from the Vishay General Semiconductor BY500 series, housed in a DO-201AD plastic package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current rating of 5.0 A. The device exhibits a soft recovery characteristic with a typical reverse recovery time of 200 ns and a maximum instantaneous forward voltage of 1.35 V at rated current. It supports a peak forward surge current of 200 A and operates within a junction temperature range of -50 °C to +125 °C.
Feature Summary
- Soft recovery fast switching design for high efficiency
- Low leakage current and low forward voltage drop
- High forward surge capability
- Matte tin plated leads solderable per J-STD-002
Applications
- Medium frequency rectification in switching mode power supplies
- Inverter and converter circuits
- TV scanning circuits
- Ultrasonic systems
- Speed controlled DC motors
Procurement Notes
Verify that the specific ordering suffix /73 corresponds to the ammo pack delivery mode as documented in the official Vishay datasheet. Confirm RoHS compliance status associated with the E3 suffix. Ensure technical parameters match application requirements before procurement. Validate component authenticity through authorized channels.
Selection Notes
Select this component for applications requiring high voltage blocking capability up to 800 V combined with moderate current handling. The soft recovery profile minimizes electromagnetic interference during switching transitions. Consider thermal management constraints given the 22 °C/W thermal resistance. Verify lead length requirements for heatsinking compatibility.
Part Context
This part belongs to the BY500 series of soft recovery fast-switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 100 V to 800 V. All members share identical current ratings and package dimensions, differing primarily in their breakdown voltage specifications.
Replacement Considerations
Direct substitutes include other BY500 series variants such as BY500-600 or BY500-400 if lower voltage ratings are acceptable. Cross-brand replacements must match the 5 A current rating, 800 V reverse voltage, DO-201AD package, and soft recovery characteristics.
