DDTA144WUA-7

Overview

The DDTA144WUA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-323 package. It features built-in biasing resistors with nominal values of R1 = 47 kΩ and R2 = 22 kΩ. The device supports a maximum 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 from -55°C to +150°C. The DC current gain (hFE) has a minimum value of 56.

Feature Summary

Epitaxial planar die construction for reliable performance
Integrated unequal biasing resistors simplify circuit design
Lead-free plating with RoHS compliance

Applications

General-purpose switching applications
Driver circuits for logic interfaces
Inverter configurations

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance before finalizing procurement specifications.

Selection Notes

Select this component when a PNP digital transistor with a 47 kΩ base resistor and 22 kΩ emitter resistor is required. Ensure the application operates within the specified -50 V supply limit and 200 mW power dissipation constraints.

Part Context

This part belongs to the DDTA144 series of pre-biased transistors. It serves as the PNP counterpart to the DDTC144WUA NPN type, providing complementary functionality within the same surface mount footprint.
