DDTC144VUA-7

Overview

The DDTC144VUA-7-F is a single NPN pre-biased transistor from Diodes Incorporated, housed in an SOT323 surface-mount package. It integrates built-in biasing resistors with nominal values of R1 = 47 kΩ and R2 = 10 kΩ. The device supports a supply voltage (VCC) of 50 V and a continuous collector current (IC) of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning -55°C to +150°C. The DC current gain (hFE) has a minimum value of 33, and the transition frequency (fT) is typically 250 MHz.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated base and emitter biasing resistors simplify circuit design
Surface mount package optimized for automated assembly processes
Totally lead-free and fully RoHS compliant

Applications

General-purpose switching applications
Driver circuits for logic interfaces
Low-power digital signal buffering

Procurement Notes

Verify the complete part number includes the suffix '-7-F' to ensure correct packaging and compliance specifications. Confirm that the required resistor ratio matches the specific application needs, as other variants within the DDTC144 series offer different resistance values. Ensure the selected component meets all environmental and regulatory standards relevant to the target market.

Selection Notes

Select this component when a single NPN transistor with integrated biasing is required in a compact SOT323 footprint. Verify that the 47kΩ input resistor and 10kΩ emitter resistor configuration aligns with the drive requirements. Consider the 200mW power dissipation limit and thermal resistance characteristics during PCB layout planning.

Part Context

This component belongs to the DDTC (R1≠R2 SERIES) UA family, which provides various combinations of internal biasing resistors. The 'UA' designation specifically indicates the SOT323 package type. Other members of this series include parts with different resistor ratios such as DDTC144WUA or DDTC123JUA, allowing designers to choose based on specific gain and input impedance requirements.

Replacement Considerations

Direct replacements must match the NPN polarity, SOT323 package, and similar electrical characteristics. Check datasheets for equivalent VCEO, IC, and PD ratings. Verify that the replacement part's internal resistor values are compatible with the existing circuit design to avoid performance deviations.
