Overview
The BYW98-200 is a high-efficiency fast recovery rectifier diode manufactured by STMicroelectronics in the DO-201AD package. It features a repetitive peak reverse voltage (VRRM) of 200 V and an average forward current (IF(AV)) of 3 A at 75°C. The device supports a repetitive peak forward current (IFRM) of 110 A and a non-repetitive surge forward current (IFSM) of 70 A. Key electrical parameters include a maximum forward voltage drop (VF) of 0.85 V, a maximum reverse leakage current (IR) of 0.5 mA at 100°C, and a maximum reverse recovery time (trr) of 35 ns.
Feature Summary
- Designed for low conduction losses and negligible switching losses
- Features low forward and reverse recovery times
- Suitable for switching mode base drive and transistor circuits
Applications
- Switching mode power supplies
- Base drive circuits
- Transistor driver applications
Procurement Notes
Verify the specific ordering code against the required delivery mode, as the standard BYW98-200 is supplied in Ammopack while the BYW98-200RL variant uses Tape and reel packaging. Confirm that the component marking matches the part number exactly. Ensure the DO-201AD package dimensions align with the target PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a fast recovery rectifier with a 200 V blocking capability is required. The device is appropriate for applications demanding low reverse recovery charge and short transition times. Consider the thermal resistance characteristics and the 150 °C maximum junction temperature rating to ensure adequate heat dissipation under the expected operating load conditions.
Part Context
This component belongs to the family of high-efficiency fast recovery rectifiers produced by STMicroelectronics. These devices are engineered to replace standard rectifiers in high-frequency applications where minimizing switching losses is critical. The technology focuses on reducing both conduction and reverse recovery energy to improve overall system efficiency.
Replacement Considerations
Check datasheets for alternative fast recovery rectifiers offering compatible 200 V ratings and similar reverse recovery times. Verify that substitute components fit within the DO-201AD mechanical envelope and meet the same thermal and electrical specifications.
