Overview
The BYWB29-150-E3/45 is an ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated pellet chip junction and operates in the TO-263AB (D2PAK) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 150 V, a maximum average forward rectified current of 8.0 A at TC = 105 °C, and a peak forward surge current of 100 A. The device exhibits an ultrafast recovery time of 25 ns and a typical junction capacitance of 45 pF. It supports an operating temperature range from -65 °C to +150 °C.
Feature Summary
- Ultrafast recovery time for high efficiency and low switching losses
- Glass passivated pellet chip junction for reliability
- High forward surge capability
- Low forward voltage drop
Applications
- High frequency rectification in switching mode power supplies
- Inverters
- Freewheeling diodes
- DC/DC converters
- Other power switching applications
Procurement Notes
Verify the specific ordering code against the manufacturer's official documentation to ensure correct package type and compliance status. Confirm that the E3 suffix indicates RoHS compliance and commercial grade material categorization. Check for any regional technical support contacts if integration issues arise during procurement or assembly phases.
Selection Notes
Select this component when designing circuits requiring fast recovery characteristics and high surge current handling within a D2PAK footprint. Ensure thermal management strategies account for the specified case temperature ratings. Validate that the 150 V reverse voltage rating aligns with the peak inverse voltage requirements of the target application circuit.
Part Context
This part belongs to the BYW29/BYWB29 series of ultrafast rectifiers offered by Vishay. The series includes variants with different voltage ratings ranging from 50 V to 200 V. The BYWB29 designation specifically denotes the surface-mount D2PAK (TO-263AB) package configuration, distinguishing it from the through-hole TO-220AC versions.
Replacement Considerations
Direct substitutes within the same series include BYWB29-50, BYWB29-100, and BYWB29-200, which share identical package and current specifications but differ in reverse voltage ratings.
