ACDBA140-HF

Single Diodes Overview

The ACDBA140-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface mount applications. It features a DO-214AC (SMA) package and operates as a single diode configuration. Key electrical parameters include a maximum repetitive reverse voltage (VRRM) of 40 V and an average forward current (IF) of 1 A. The device exhibits a low forward voltage drop (VF) of 500 mV at rated current and a maximum reverse leakage current (IR) of 500 uA. It supports a forward surge current (IFSM) of 9 A and functions within a temperature range of -55 C to +150 C junction temperature.

Single Diodes Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Comchip Technology or authorized distributors before procurement. Confirm that the DO-214AC package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal design constraints. Cross-reference the part number ACDBA140-HF with official manufacturer catalogs to avoid counterfeit components.

Single Diodes Selection Notes

Select this component when a compact SMA package is required for 40V, 1A Schottky rectification. It is suitable for designs prioritizing low forward voltage loss and high thermal stability. Consider the 500 uA reverse leakage specification for sensitive circuitry. Evaluate the 9 A surge rating against potential inrush currents in the target application environment.

Single Diodes Part Context

This part belongs to Comchip Technology's automotive-grade Schottky diode series. It complements other variants like the ACDBQC140L-HF (DFN1006/SOD-923F) and CDBHD140L-HF (Bridge Rectifier). The ACDBA140-HF specifically targets space-constrained surface mount designs requiring robust performance in automotive and industrial power management systems.

Single Diodes Replacement Considerations

Direct substitutes may include other 40V 1A SMA Schottky diodes from manufacturers such as Vishay or Diodes Inc., provided pinout and thermal characteristics are compatible. Verify equivalent VF and IR specs. No specific public substitute part numbers are confirmed in the source data.
