DDTC144VUA-7-F

Overview

The DDTC144VUA-7-F is a single NPN pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT323 surface-mount package. It features built-in biasing resistors with nominal values of R1 = 47 kΩ and R2 = 10 kΩ. The device supports a maximum supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 33 at VOUT = 5 V and IOUT = 5 mA, and a typical gain-bandwidth product (fT) of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55 °C to +150 °C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Surface mount package optimized for automated assembly

Applications

• General-purpose switching applications
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the complete part number including the suffix '-7-F' to ensure correct packaging configuration. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation before procurement. Check for specific automotive qualification requirements if the application demands AEC-Q100 standards or PPAP capability.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is required. Ensure the 47 kΩ input resistor value aligns with the driving source impedance. Verify that the 100 mA output current rating meets the load requirements and that the SOT323 package dimensions fit the PCB layout constraints.

Part Context

This component belongs to the DDTC144 series of pre-biased transistors from Diodes Incorporated. It shares the same package and general electrical characteristics as other variants in the UA series, distinguished primarily by its specific internal resistor ratio. The 'V' designation indicates the 47 kΩ/10 kΩ resistor combination.

Replacement Considerations

Direct substitutes within the same family include DDTC144WUA-7-F, which offers different resistor values (47 kΩ/22 kΩ). Cross-manufacturer equivalents such as MUN2213T1G may be considered but require verification of pinout compatibility and electrical parameter alignment.
