CDSH3-4448C-G

Diode Arrays Overview

The CDSH3-4448C-G is a general-purpose switching diode array manufactured by Comchip Technology in an SOT-523 surface-mount package. It features two independent diodes configured with a common cathode. The device supports a maximum repetitive peak reverse voltage of 80V and an average forward rectified current of 250mA. Key electrical specifications include a maximum non-repetitive peak forward surge current of 2A, a maximum DC forward voltage of 1.25V at 250mA, and a typical reverse leakage current of 25µA at 80V. The component operates within a junction temperature range of -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance when sourcing. Confirm the package type matches the required footprint for PCB layout. Ensure the selected distributor provides valid traceability documentation. Cross-reference the datasheet revision date to confirm parameter stability. Validate that the ordering code corresponds exactly to the dual common-cathode variant rather than single-diode alternatives.

Diode Arrays Selection Notes

Select this component when a compact dual-diode solution is required for low-voltage switching tasks. The 80V rating suits low-power signal lines but may be insufficient for higher voltage industrial environments. Consider the 250mA current limit for load requirements. The SOT-523 form factor is ideal for dense consumer electronics where board space is constrained compared to larger packages like SOD-323.

Diode Arrays Part Context

This part belongs to Comchip Technology's series of small-signal switching diodes. It serves as a dual-diode alternative to single-unit devices, reducing component count in designs requiring isolation or steering functions. The family typically includes variants with different voltage ratings and package options to accommodate diverse application constraints.

Diode Arrays Replacement Considerations

Public confirmed substitutes include MMBD4448HTC-TP from Micro Commercial Components. Verify pinout compatibility and thermal characteristics before substitution. Ensure the replacement part meets the same 80V reverse voltage and 250mA current specifications.
