DDTA144WCA-7

Overview

The DDTA144WCA-7 is a single PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 surface-mount package. It integrates built-in biasing resistors with typical 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 (Iout) of -100 mA. Electrical characteristics include a minimum DC current gain (Gl) of 56 at -10 mA output and a transition frequency (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 logic interfaces
Power management control stages

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the component meets all required environmental standards, including RoHS compliance and halogen-free specifications. Ensure the selected packaging format aligns with manufacturing requirements. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a PNP configuration with integrated base and emitter resistors is required. The 47 kΩ input resistor value suits applications needing moderate drive currents. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Consider the SOT23 package dimensions for PCB layout constraints.

Part Context

This component belongs to the DDTA (R1≠R2 SERIES) CA family of 50V PNP pre-biased transistors. It is designed as a complementary counterpart to the DDTC NPN series. The 'CA' designation indicates specific packaging and material attributes defined by Diodes Incorporated for this product line.

Replacement Considerations

Direct substitutes within the same series include DDTA144VCA-7-F (47kΩ/10kΩ). Other compatible parts may exist within the broader DDTA family, but resistor ratios must be verified. Always consult the latest datasheet for pin compatibility and electrical parameter matching.
