BYW29-200HE3/45

Overview

The BYW29-200HE3/45 is an ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated pellet chip junction and is housed in a TO-220AC package with two terminals. The device supports a maximum repetitive peak reverse voltage of 200 V, a maximum average forward rectified current of 8.0 A at a case temperature of 105 °C, and a peak forward surge current of 100 A. Its electrical characteristics include a maximum instantaneous forward voltage of 1.3 V at 20 A and 25 °C, a maximum DC reverse current of 10 μA at 25 °C, and a maximum reverse recovery time of 25 ns. The operating and storage temperature range spans from -65 to +150 °C.

Procurement Notes

Verify the specific ordering code against official Vishay documentation to ensure compliance with RoHS standards and correct package type. Confirm that the component meets the required thermal resistance and mounting torque specifications for your application. Check for any recent product change notifications or end-of-life announcements directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring fast recovery times and low switching losses in high-frequency environments. Ensure the thermal management system can maintain the case temperature within limits to support the rated 8.0 A average forward current. Verify that the 200 V reverse voltage rating provides adequate margin for the peak inverse voltages present in the target circuit topology.

Part Context

This part belongs to the BYW29 series of ultrafast rectifiers offered by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 200 V. These components are designed for use in power switching applications where high efficiency and rapid recovery characteristics are critical for performance.

Replacement Considerations

Direct substitutes may include other Vishay parts within the BYW29 series with matching voltage ratings, such as BYW29-150 or BYW29-100, provided the reverse voltage requirements align. Cross-manufacturer replacements must be evaluated for equivalent ultrafast recovery times, forward voltage drops, and thermal characteristics.
