BYG23T-M3/TR3

Overview

The BYG23T-M3/TR3 is a high voltage ultrafast avalanche SMD rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated pellet chip junction in an SMA (DO-214AC) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 1300 V, a maximum DC forward current of 1.0 A, and a peak forward surge current of 18 A. The device exhibits an ultra-fast reverse recovery time of 75 ns and a typical junction capacitance of 9.0 pF at 4.0 V and 1 MHz. It operates within a temperature range of -55 °C to +150 °C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the delivery mode and base quantity. The TR3 suffix indicates a 13-inch diameter plastic tape and reel with a base quantity of 7500 units. Confirm compliance requirements such as RoHS and halogen-free status, which are standard for the M3 series. Ensure the component meets the required moisture sensitivity level and thermal specifications for the intended assembly process.

Selection Notes

Select this component for designs requiring high voltage isolation up to 1300 V and fast switching speeds. The 1.0 A average forward current rating suits moderate power applications. Consider the thermal resistance characteristics when designing heat dissipation strategies. The SMA package offers a compact footprint for surface mount technology. Validate the avalanche energy rating if the application involves inductive load switching.

Part Context

This part belongs to the BYG23T series of high voltage ultrafast avalanche SMD rectifiers from Vishay. The series is designed for demanding power electronics environments where rapid switching and high voltage blocking are critical. The M3 suffix denotes a halogen-free, RoHS-compliant version that also passes JESD 201 class 2 whisker tests. The product line emphasizes reliability through glass passivation and robust mechanical construction.

Replacement Considerations

Direct substitutes must match the 1300 V reverse voltage, 1.0 A forward current, and SMA package. Verify that alternative components offer comparable reverse recovery times and avalanche ratings. Check for identical pinout configurations and thermal performance characteristics to ensure seamless integration without circuit redesign.
