Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm compliance with halogen-free requirements and AEC-Q101 automotive qualification standards. Ensure that the procurement specifications align with the required voltage ratings and package dimensions defined in the datasheet to prevent integration errors during assembly.

Selection Notes

Select this component when designing circuits requiring robust avalanche energy handling capabilities alongside standard rectification functions. The SMA (DO-214AC) package provides a compact footprint ideal for space-constrained designs. Consider the thermal resistance values and operating temperature limits to ensure adequate heat dissipation under maximum load conditions in the final application environment.

Part Context

This part belongs to the BYG10 series of standard avalanche SMD rectifiers, which includes variants with different voltage ratings such as BYG10D through BYG10Y. The series utilizes the eSMP Series K technology to deliver high reliability in a surface-mount form factor. The HE3 suffix indicates RoHS compliance and AEC-Q101 qualification, distinguishing it from commercial grade alternatives.

Replacement Considerations

Direct substitutes within the same family include BYG10MHM3_A/H, which shares identical electrical characteristics but may differ in material categorization regarding halogen content. Other voltage-rated variants like BYG10K or BYG10J can be considered if the circuit design allows for lower reverse voltage margins.

FAQ

What is the pulse energy rating for the BYG10MHE3_A/H?

The device supports a non-repetitive pulse energy of 20 mJ in avalanche mode when the reverse current is 1 A and the junction temperature is 25 °C.

How is the cathode polarity identified on the component?

Polarity is indicated by a color band located on one end of the package, which denotes the cathode side.

Is the BYG10MHE3_A/H suitable for high-frequency switching applications?

While it features a fast reverse recovery time of 4 μs, it is classified as a standard recovery rectifier intended primarily for general-purpose rectification and freewheeling duties rather than ultra-high-frequency conversion.
