Overview
The BA159-E3/54 is a single silicon junction switching diode manufactured by Vishay General Semiconductor. It features a DO-204AL axial leaded package designed for through-hole mounting. The device supports a maximum average forward current of 1 A and a peak repetitive reverse voltage of 1 kV. Key electrical characteristics include a maximum forward voltage of 1.3 V, a peak non-repetitive forward surge current of 20 A, and a peak reverse recovery time of 500 ns. It operates within a junction temperature range of -65°C to 175°C.
Feature Summary
- High voltage blocking capability with 1 kV reverse voltage rating
- Robust thermal performance supporting operation up to 175°C
- Fast recovery characteristics suitable for switching applications
Applications
- General purpose rectification in power supplies
- Free-wheeling diodes in inductive load circuits
- Protection against voltage spikes in electronic systems
Procurement Notes
Verify the specific suffix E3/54 to confirm RoHS compliance and standard tape-and-reel packaging configuration. Ensure the ordering part number matches the required 1 kV rating, as other variants in the BA159 series may offer different voltage levels or packaging options. Cross-reference the manufacturer datasheet for exact mechanical dimensions and handling instructions before finalizing procurement.
Selection Notes
Select this component when a high-voltage, fast-recovery diode is required for through-hole assembly. The 1 kV rating distinguishes it from lower voltage counterparts like the BA158 (600 V) or BA157 (400 V). Consider the 500 ns recovery time for frequency requirements and ensure the DO-204AL footprint fits the PCB layout constraints.
Part Context
This part belongs to the Vishay BA15x series of glass-passivated silicon switching diodes. The series offers various voltage ratings including 400 V, 600 V, and 1 kV. The BA159 specifically targets the 1 kV segment, providing a standardized solution for high-voltage rectification needs in industrial and consumer electronics.
Replacement Considerations
Direct substitutes within the same family include BA159GP-E3/54 (glass passivated) and BA159DGP-E3/54 (800 V variant, verify voltage compatibility). Other manufacturers' 1 A, 1 kV DO-204AL diodes may serve as functional equivalents if electrical parameters match.
