Overview
The BY228-15TAP is a standard avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a maximum average forward current of 3 A and a maximum repetitive peak reverse voltage of 1200 V. The device utilizes a hermetically sealed SOD-64 package with plated axial leads. Electrical characteristics include a maximum forward voltage of 1.5 V at 5 A, a maximum reverse current of 25 µA at 1200 V, and a total reverse recovery time of 20 µs. The junction temperature rating reaches 140 °C.
Feature Summary
- Hermetically sealed glass passivated junction
- Standard avalanche capability for energy dissipation
- Sintered glass case construction
Applications
- High voltage rectification
- Efficiency diode in horizontal deflection circuits
Procurement Notes
Verify the specific ordering code BY228-15TAP to confirm the ammopack packaging configuration containing 2500 units per pack. Ensure the required minimum order quantity aligns with the manufacturer's specified 12 packs. Confirm that the SOD-64 through-hole package meets the mechanical constraints of the target printed circuit board layout before finalizing procurement.
Selection Notes
Select this component when a high-voltage rectifier with avalanche capability is required. The 1200 V rating distinguishes it from the 1000 V BY228-13 variant. Consider the 20 µs reverse recovery time for switching applications. Verify thermal management requirements against the 70 K/W junction-to-ambient thermal resistance specification for the chosen mounting position.
Part Context
This part belongs to the BY228 series of standard avalanche sinterglass diodes produced by Vishay Semiconductors. The series includes variants differentiated primarily by their reverse voltage ratings, specifically the 1000 V BY228-13 and the 1200 V BY228-15. All models share the same physical SOD-64 package and general electrical structure.
Replacement Considerations
The BY228-13 serves as a lower voltage alternative within the same series. Cross-referencing requires verifying that the application voltage does not exceed the 1000 V rating of the BY228-13.
