DDC144EU-7-F

Overview

The DDC144EU-7-F is an NPN pre-biased small signal dual surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrates built-in biasing resistors within a compact SOT363 package. The device operates with a supply voltage of up to 50 V and supports a continuous collector current of 30 mA, with a peak DC collector current rating of 100 mA. Power dissipation is rated at 200 mW, and the transition frequency reaches 250 MHz. Each internal transistor includes two 47 kOhm input resistors (R1 and R2). The component functions reliably across an operating temperature range from -55°C to +150°C.

Procurement Notes

Verify the active status and ordering suffixes against official Diodes Incorporated documentation before procurement. Confirm that the SOT363 package dimensions and marking codes match project requirements. Ensure compliance with environmental directives such as RoHS and REACH if applicable to the target market. Review the datasheet for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a minimal footprint. The 47 kOhm resistor values are suitable for standard logic interface levels. Consider the thermal resistance and power derating curves for high-temperature environments. Verify that the 30 mA continuous current rating meets the load requirements of the specific application circuit.
