Diode Arrays Procurement Notes

Verify the specific ordering suffix to confirm packaging quantity and reel diameter specifications. Confirm whether the HM3 suffix variant is required for automotive grade compliance versus the standard M3 commercial grade designation. Ensure the selected component matches the intended thermal management requirements for the target application environment.

Diode Arrays Selection Notes

Select this component when a 200 V blocking capability is required alongside ultrafast switching speeds. The TO-277A package offers a compact footprint suitable for space-constrained designs. Consider the thermal resistance characteristics and derating curves to ensure reliable operation under expected load conditions and ambient temperatures.

Diode Arrays Part Context

This part belongs to the eSMP series of high current density surface mount ultrafast rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, such as the UH4PBC for 100 V and UH4PCC for 150 V, sharing identical physical dimensions and electrical characteristics except for the reverse voltage rating.

Diode Arrays Replacement Considerations

Direct parameter-equivalent replacements include the UH4PBC or UH4PCC from the same manufacturer family, provided the lower voltage ratings are acceptable for the circuit design. Verify pinout compatibility and thermal performance before substituting.
