Overview
The BYWB29-100HE3_A/P is an ultrafast rectifier from the Vishay BYWB29 series, housed in a D2PAK (TO-263AB) surface-mount package. It features a glass passivated pellet chip junction and supports a maximum repetitive peak reverse voltage of 100 V with a maximum average forward rectified current of 8.0 A at a case temperature of 105 °C. The device exhibits a typical instantaneous forward voltage of 0.8 V at 8.0 A and 150 °C, alongside a maximum reverse recovery time of 25 ns. It withstands a peak forward surge current of 100 A and operates within a junction temperature range of -65 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 rectifier of switching mode power supplies
- Inverters
- Freewheeling diodes
- DC/DC converters
- Power switching applications
Procurement Notes
Verify that the specific ordering code matches the required package type and qualification level. Confirm whether the suffix indicates standard commercial grade or automotive-grade AEC-Q101 compliance. Ensure the component meets the necessary RoHS and halogen-free requirements for your assembly process. Cross-reference the datasheet revision date to confirm the accuracy of the electrical parameters before finalizing procurement.
Selection Notes
Select this component when a single ultrafast rectifier in a D2PAK package is required for high-frequency power conversion. The 100 V rating suits low-voltage output stages in SMPS and DC/DC converters. Consider the thermal resistance and derating curves if operating near the maximum current limit. Verify that the 25 ns reverse recovery time aligns with the switching frequency of the target circuit to minimize losses.
Part Context
This part belongs to the Vishay BYW29/BYWB29 series of ultrafast rectifiers, available in both through-hole TO-220AC and surface-mount D2PAK packages. The series offers various voltage ratings ranging from 50 V to 200 V. The BYWB29 variant specifically denotes the surface-mount configuration, providing a compact solution for modern PCB designs requiring high current handling and fast switching characteristics.
Replacement Considerations
Direct substitutes include other parts from the BYW29/BYWB29 family with matching voltage and current ratings, such as BYWB29-50 or BYWB29-150, provided the reverse voltage requirements are met. Ensure any replacement maintains the D2PAK footprint and similar thermal and electrical performance characteristics.
