Overview
The BY255 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features an average forward current rating of 3 A and a maximum repetitive peak reverse voltage of 1300 V. The device exhibits a forward voltage drop below 1.1 V at 3 A and a typical reverse recovery time of 1500 ns. Thermal resistance from junction to ambient is less than 25 K/W, while junction-to-lead resistance is under 10 K/W. Operating temperatures range from -50°C to +150°C for the junction and -50°C to +175°C for storage.
Feature Summary
- High voltage capability with a 1300 V reverse voltage rating
- Standard recovery speed suitable for general-purpose applications
- Robust surge current handling up to 110 A at 60 Hz
- Low thermal resistance for efficient heat dissipation
Applications
- General purpose rectification in power supplies
- Free wheeling diodes in inductive load circuits
- AC/DC conversion stages requiring high voltage isolation
Procurement Notes
Verify the specific package type and marking code against the official Diotec datasheet before ordering. Confirm that the required operating temperature range aligns with the specified junction limits. Ensure design margins account for the derating curves provided for ambient temperatures above 25°C. Check for any automotive grade variants if higher reliability standards are necessary for the target application environment.
Selection Notes
Select this component when a 3 A current capacity and 1300 V blocking voltage are required. Consider the 1500 ns reverse recovery time for switching frequency limitations. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance. Compare against alternative series like BY1600 or BY2000 if higher voltage ratings are needed.
Part Context
This part belongs to the BY251 through BY255 series of standard recovery rectifier diodes produced by Diotec Semiconductor. The series offers varying voltage ratings while maintaining a consistent 3 A forward current capability. These devices are designed for commercial and industrial applications requiring reliable rectification performance.
Replacement Considerations
Equivalent parts include Vishay BY255GP-E3/54 and generic equivalents meeting the 3A/1300V specification. Verify pinout compatibility and thermal characteristics when substituting.
