DA228KFHT146

Diode Arrays Overview

The DA228KFHT146 is a general-purpose diode array manufactured by Rohm Semiconductor, designed for surface-mount applications. It features one pair of serially connected diodes housed in an SMD3 package, specifically TO-236-3, SC-59, or SOT-23-3. The device supports a maximum DC reverse voltage (Vr) of 80 V and an average rectified forward current (Io) of 100 mA per diode. At a forward current of 100 mA, the typical forward voltage (Vf) is 1.2 V. Reverse leakage current is specified at 100 nA when measured at 80 V. The component operates within a junction temperature range up to 150°C and holds AEC-Q101 automotive qualification.

Diode Arrays Feature Summary

• Features a single pair of serially connected diodes integrated into a compact surface-mount package.
• Qualified for automotive applications under the AEC-Q101 standard.
• Provides low reverse leakage current characteristics suitable for signal switching.

Diode Arrays Applications

• Automotive electronic circuits requiring small-signal switching
• General-purpose rectification in consumer electronics
• Signal processing interfaces in industrial control systems

Diode Arrays Procurement Notes

Verify the specific ordering suffix and tape specification against the official datasheet before procurement. Confirm that the SMD3 package variant matches the PCB footprint requirements. Ensure compliance with RoHS3 directives if required by the target assembly process. Check the supply status as components may be subject to production lifecycle changes.

Diode Arrays Selection Notes

Select this component when a dual-diode configuration with serial connection is required in a minimal footprint. The 80 V reverse voltage rating suits low-voltage signal paths. Consider the 100 mA current limit for appropriate load matching. The AEC-Q101 qualification makes it suitable for environments demanding higher reliability standards compared to standard commercial grade parts.

Diode Arrays Part Context

This part belongs to the DA228 series of diode arrays from Rohm Semiconductor. It is distinct from single diode models like the DA228KT146 by integrating two diodes in one package. The SMD3 packaging allows for automated surface-mount assembly, reducing board space compared to through-hole alternatives. It serves as a discrete solution for logic isolation or signal routing in compact designs.
