Overview
The BY448GPHE3/54 is a silicon rectifier diode manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage rating of 1650 V. The device utilizes a glass-passivated junction structure for enhanced reliability and low leakage current. It is housed in a DO-204AC (DO-15) axial leaded package, suitable for through-hole mounting applications requiring high-voltage rectification capabilities.
Feature Summary
- Glass-passivated junction construction for high reliability
- Low leakage current characteristics
- High forward surge capability
Applications
- High voltage power supply circuits
- Industrial rectification systems
- General purpose high voltage applications
Procurement Notes
Verify the exact suffix designation against official Vishay documentation to ensure correct voltage rating and packaging specifications. Confirm RoHS compliance status and environmental directives alignment prior to integration. Check for end-of-life notices or last-time-buy dates associated with this specific part number variant.
Selection Notes
Select this component when designing circuits requiring a 1650 V reverse voltage blocking capability with a 1.5 A continuous current rating. Ensure the thermal management design accommodates the forward voltage drop at rated load. Verify that the axial leaded package fits the available PCB footprint and mechanical constraints of the assembly.
Part Context
This part belongs to the BY series of fast recovery rectifiers from Vishay. These devices are characterized by their glass passivation which protects the junction against mechanical stress and moisture. The GP suffix typically indicates general-purpose performance within the lineup, while the HE3 denotes Halogen-free and RoHS compliant manufacturing processes.
Replacement Considerations
Direct substitutes must match the 1650 V reverse voltage and 1.5 A forward current ratings. Compatible alternatives include other glass-passivated axial rectifiers from Vishay such as the BYV series or equivalent parts from other manufacturers offering identical electrical parameters and DO-15 package dimensions.
