Overview
The BY133 is a standard recovery rectifier diode manufactured by Diotec Semiconductor, housed in the DO-41 axial leaded package. It features a maximum average forward current (IFAV) of 1 A and a peak repetitive reverse voltage (VRRM) of 1300 V. The device exhibits a maximum forward voltage (VF) of 1.3 V at 1 A and a typical reverse recovery time (trr) of 1500 ns. Electrical characteristics include a maximum leakage current of 5 µA at 25°C and 50 µA at 100°C when rated at VRRM. Thermal resistance from junction to ambient is less than 45 K/W, while junction-to-terminal resistance is under 15 K/W. Operating temperatures range from -50°C to +175°C.
Feature Summary
- High voltage capability with a 1300 V reverse voltage rating for robust blocking performance
- Standard recovery speed suitable for general-purpose rectification tasks
- Robust thermal management supporting operation up to 175°C junction temperature
- Compliant with RoHS and REACH directives for environmental safety
Applications
- 50/60 Hz mains rectification
- General power supply circuits
- Polarity protection applications
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the received parts match the specified DO-41 package and 1300V rating. Ensure compliance with relevant environmental standards such as RoHS and REACH as documented in the datasheet. Validate storage conditions to maintain the specified temperature range limits before installation.
Selection Notes
Select this component for designs requiring high reverse voltage blocking in a standard axial package. The 1 A current rating and 1500 ns recovery time make it appropriate for low-frequency AC-DC conversion. Consider the thermal resistance values when designing heat dissipation strategies for enclosed environments. Ensure the application does not exceed the maximum surge current ratings during transient events.
Part Context
This part belongs to the BYX series of standard recovery rectifiers produced by Diotec Semiconductor. It is designed for commercial and industrial grade applications requiring reliable performance in standard operating conditions. The DO-41 package provides a cost-effective solution for through-hole mounting in various electronic assemblies.
Replacement Considerations
Consult the official Diotec documentation for verified substitute part numbers within the same series. Cross-referencing electrical parameters such as voltage, current, and recovery time is essential when evaluating alternative components.
