Diode Arrays Procurement Notes

Verify the End-of-Life status before procurement as the CMUSH2-4 series has been transitioned to Life (EOL) by Central Semiconductor Corp. Confirm availability through authorized distributors or submit inquiries via the manufacturer's portal for potential alternate sourcing. Ensure the PBFREE suffix matches environmental compliance requirements for the target assembly process.

Diode Arrays Selection Notes

Select this component for designs requiring a compact dual-diode solution in the SOT-523 footprint. The series configuration is suitable for applications needing isolated voltage handling or specific biasing arrangements. Evaluate the 200 mA continuous current limit and 40 V reverse voltage rating against circuit demands. Consider the low junction capacitance for high-frequency signal integrity.
