CDBT-54C-HF

Diode Arrays Overview

The CDBT-54C-HF is a dual Schottky barrier rectifier from Comchip Technology, housed in an SOT-23-3 (SC-59) surface-mount package. It features two independent diodes configured as a common cathode pair. The device supports a maximum repetitive peak reverse voltage of 30 V and a forward current of 200 mA. Constructed with silicon epitaxial planar chips and metal-silicon junctions, it offers low forward voltage drop and high surge capability. The component operates within a temperature range of -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific suffix 'C' indicates the common cathode dual configuration distinct from single diode variants like CDBT-54-HF. Confirm RoHS compliance status and lead-free termination specifications against the latest manufacturer datasheet. Ensure the ordering part number matches the required dual-diode topology for the intended circuit design.

Diode Arrays Selection Notes

Select this component when space-constrained designs require dual Schottky rectification in an SOT-23 footprint. Consider the 200 mA forward current limit and 30 V reverse voltage rating for suitability. Evaluate thermal management requirements given the small package size and operating temperature range up to 150°C.

Diode Arrays Part Context

This part belongs to Comchip's CDBT series of small signal Schottky diodes. It complements single-diode versions and other package options within the manufacturer's discrete semiconductor portfolio. The series emphasizes low profile and high reliability for surface-mount assembly processes.

Diode Arrays Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other manufacturers offering SOT-23 dual Schottky diodes with matching 30V/200mA ratings if substitution is necessary.
