Overview
The BYT03-400RL is an ultrafast diode utilizing planar technology, designed for switching mode base drive and transistor circuits. It features a 400 V repetitive peak reverse voltage and a 3 A average forward current rating at 55°C. The device operates with a maximum junction temperature of 150°C and exhibits low conduction losses alongside negligible switching losses. Its axial DO-201AD package supports applications requiring fast recovery characteristics.
Feature Summary
- Ultrafast recovery performance with minimal switching losses
- Low forward and reverse recovery times for high efficiency
- Planar technology construction ensuring ruggedness
Applications
- Switching mode base drive circuits
- Transistor circuits
- Free wheeling diodes in power supplies
- General power switching applications
Procurement Notes
Verify the specific ordering code BYT03-400RL to confirm tape and reel packaging containing 1900 units per base quantity. Ensure the component meets the required thermal resistance specifications for your heatsink configuration. Confirm that the application does not involve life support devices without express written approval from STMicroelectronics.
Selection Notes
Select this component when low conduction losses and fast switching speeds are critical. The 400V rating suits medium-voltage rectification tasks. Consider the 3A continuous current capability and the 60A surge rating for transient handling. Evaluate thermal management requirements based on the specified junction-to-ambient resistance values.
Part Context
This part belongs to the BYT03 series of high-efficiency ultrafast diodes manufactured by STMicroelectronics. The series utilizes advanced planar technology to achieve superior switching performance compared to standard rectifiers. The RL suffix specifically denotes the tape and reel delivery format, distinguishing it from the standard ammpack version.
Replacement Considerations
Direct substitutes must match the 400V reverse voltage, 3A forward current, and ultrafast recovery characteristics within the DO-201AD package. Verify equivalent dynamic electrical parameters such as reverse recovery time and peak reverse recovery current before integration.
