Applications
- Switching mode base drive circuits
- Transistor circuits
- Free wheeling diodes in power supplies
- General power switching applications
Procurement Notes
Verify the specific ordering suffix to confirm the delivery mode. The standard BYT03-400 designation corresponds to the Ammopack delivery mode containing 600 units per base quantity. The BYT03-400RL variant indicates Tape & Reel packaging with a base quantity of 1900 units. Ensure the required package configuration matches the intended manufacturing process before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring fast recovery characteristics and low switching losses. The 400 V reverse voltage rating suits applications operating within this potential range. Consider the thermal resistance parameters and lead length requirements for adequate heat dissipation in the target environment.
Part Context
This component belongs to the BYT03 series of high-efficiency ultrafast diodes manufactured by STMicroelectronics. These devices are engineered using advanced planar technology to provide superior performance in high-frequency switching environments compared to standard rectifiers.
Replacement Considerations
Direct substitutes include the SMBYT03-400 from Zibo Seno Electronic En, which shares similar specifications as a surface mount ultrafast diode.
