Overview
The BY550-50 is a standard recovery rectifier diode manufactured by Diotec Semiconductor, designed for general-purpose applications. It features an average forward current rating of 5 A and a maximum repetitive peak reverse voltage of 50 V. The device exhibits a typical junction-to-ambient thermal resistance of 25 K/W and operates within a junction temperature range of -50°C to +175°C. Key electrical characteristics include a forward voltage below 1.0 V at 5 A, a leakage current under 5 µA at rated voltage, and a typical reverse recovery time of 1500 ns.
Feature Summary
- Standard recovery rectifier technology with low forward voltage drop
- High surge current capability for half-sine wave pulses
- Wide operating junction temperature range up to 175°C
Applications
- General purpose rectification in power supplies
- Bridge rectifier circuits
- Free-wheeling diodes in inductive load switching
Procurement Notes
Verify the specific part number suffix against official Diotec documentation to confirm exact voltage ratings and package variants. Ensure compliance with RoHS and halogen-free requirements as stated in the datasheet. Confirm lead availability and production timelines directly with authorized distributors or the manufacturer prior to ordering.
Selection Notes
Select this component for circuits requiring robust 5 A continuous current handling with fast standard recovery characteristics. Evaluate thermal management needs based on the 25 K/W junction-to-ambient resistance. Consider the 1500 ns reverse recovery time for switching frequency limitations in the target application design.
Part Context
This component belongs to the BY550 series of standard recovery rectifiers from Diotec Semiconductor. The series covers various voltage ratings from 50 V to 2000 V, all sharing the same DO-201 axial leaded package and 5 A current rating family specifications.
Replacement Considerations
Check for equivalent parts in the BY550 series with matching voltage ratings. Verify that any substitute maintains the 5 A current rating and similar reverse recovery time specifications.
