Diode Arrays Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm compliance requirements. The HM3 suffix indicates halogen-free, RoHS-compliant materials and AEC-Q101 qualification. Confirm that the P suffix corresponds to the tube delivery mode containing 50 units per tube as specified in the manufacturer's ordering information section.

Diode Arrays Selection Notes

Select this component when low forward voltage drop is critical for efficiency in high-current applications. The TMBS technology offers superior performance compared to standard Schottky rectifiers. Ensure the operating environment accommodates the wide thermal range up to 175 °C. Verify that the 45 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.
