Overview
The BY127MGP-E3/54 is a miniature glass-passivated junction rectifier manufactured by Vishay General Semiconductor. It features a Superectifier structure for high reliability and cavity-free construction. The device provides a maximum repetitive peak reverse voltage of 1250 V and supports a maximum average forward rectified current of 1.75 A at an ambient temperature of 55 °C with specified lead lengths. Peak forward surge capability reaches 50 A under standard test conditions.
Feature Summary
- Superectifier structure designed for high reliability applications
- Cavity-free glass-passivated junction construction
- Low leakage current performance below 1 μA
- High forward surge current capability
Applications
- High voltage rectification in power supplies
- Inverter circuits
- Converter systems
- Freewheeling diodes for consumer electronics
- Automotive electronic applications
Procurement Notes
Verify the specific ordering suffix to confirm environmental compliance status. The E3 suffix indicates RoHS compliance for commercial grade products, while the HE3 suffix denotes AEC-Q101 qualification for automotive standards. Confirm package availability matches project requirements, as options include paper tape and reel or ammo pack configurations.
Selection Notes
Select this component when high voltage blocking capabilities are required alongside moderate continuous current ratings. The DO-204AC (DO-15) package facilitates through-hole mounting. Ensure thermal management aligns with the specified operating junction temperature range of -65 °C to +175 °C for the intended application environment.
Part Context
This part belongs to the BY127 series of miniature glass-passivated junction rectifiers from Vishay. These components utilize a Superectifier structure to enhance reliability compared to standard junction designs. The product line includes variants with different qualification levels, such as commercial and automotive grades, sharing similar electrical characteristics but differing in testing standards.
Replacement Considerations
Direct substitutes must match the 1250 V reverse voltage rating and 1.75 A average forward current capacity. Verify that alternative components support the DO-204AC package and meet the same thermal resistance specifications. Automotive replacements require AEC-Q101 qualification.
