DCX144EU-7

Overview

The DCX144EU-7 is a complementary pre-biased transistor array manufactured by Diodes Incorporated, featuring one NPN and one PNP bipolar junction transistor within a single SOT363 surface-mount package. The device integrates internal bias resistors with nominal values of 47 kΩ for both the base (R1) and emitter (R2). It supports a supply voltage of 50 V and handles a continuous collector current of 100 mA per element. Key electrical characteristics include a minimum DC current gain of 68 at 5 mA and 5 V, a peak output current of 100 mA, and a transition frequency of 250 MHz. The component operates across a temperature range from -55°C to +150°C with a total power dissipation rating of 200 mW.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation before procurement. The provided datasheet lists the DCX144EUQ-7-F variant as active, while other suffixes may carry different statuses such as NRND. Confirm that the specific part number matches the required automotive qualification or standard industrial grade specifications defined in the ordering information table.

Selection Notes

Select this component when a complementary pair of pre-biased transistors is required in a minimal footprint. Ensure the application voltage does not exceed the 50 V supply limit and that the thermal environment allows for 200 mW dissipation without exceeding the maximum junction temperature. Verify that the 47 kΩ internal resistor values align with the intended input drive currents and logic thresholds.

Part Context

This component belongs to the DCX(XXXX)U series of 50V complementary pre-biased transistors. The series offers various resistor combinations to suit different logic families and drive requirements. The DCX144EU specifically denotes the 47 kΩ / 47 kΩ resistor configuration within the SOT363 package family.

Replacement Considerations

For automotive applications requiring AEC-Q101 qualification, consider the DCX144EUQ-7-F variant. For non-automotive designs, verify availability of the DCX144EU-7-F variant which shares identical electrical characteristics but may differ in manufacturing site or packaging details.
