BA159DGP-E3/54

Overview

The BA159DGP-E3/54 is a glass-passivated standard recovery rectifier manufactured by Vishay General Semiconductor. It features a single diode configuration housed in a DO-204AL (DO-41) axial through-hole package. The device supports a maximum average forward current of 1 A and a peak repetitive reverse voltage of 800 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 20 A, a typical reverse leakage current of 5 µA at rated voltage, and a peak reverse recovery time of 500 ns. The junction temperature range extends from -65°C to +175°C.

Feature Summary

• Glass passivation provides stable performance and environmental protection for the silicon junction.
• Superectifier structure ensures cavity-free reliability and high forward surge capability.
• Standard recovery characteristics are optimized for general-purpose rectification applications.

Applications

• High voltage rectification in power supplies
• Inverter and converter circuits
• Freewheeling diode implementations

Procurement Notes

Verify the specific suffix E3/54 against official Vishay documentation to confirm RoHS compliance and reel packaging specifications. Ensure the 800V rating aligns with circuit requirements rather than assuming generic 1kV ratings common in the BA159 series. Confirm availability status as distribution data may vary.

Selection Notes

Select this component when an 800V blocking voltage is required alongside a 1A continuous current capacity. The 500ns recovery time distinguishes it from faster switching variants or slower high-voltage types. Verify that the DO-204AL package fits the mechanical constraints of the target assembly.

Part Context

This part belongs to the Vishay BA159 series of glass-passivated rectifiers. While sharing the same physical footprint and current rating as other BA159 variants, the DGP designation specifically indicates an 800V reverse voltage rating, differentiating it from the 1000V BA159 and 600V BA158 models within the same product family.

Replacement Considerations

BA159-E3/54 offers identical mechanical and current specifications but provides a higher 1000V reverse voltage rating. BA158-E3/54 shares the 1A current rating but operates at a lower 600V reverse voltage. Cross-reference datasheets to ensure voltage margins are maintained during substitution.
