DDTA113ZCA-7-F

Overview

The DDTA113ZCA-7-F is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 surface-mount package. It integrates internal biasing resistors with values of R1 = 1 kΩ and R2 = 10 kΩ. The device supports a maximum supply voltage (VCC) of -50 V and a continuous output current (Iout) of -100 mA. Electrical characteristics include a minimum DC current gain (Gl) of 33 at -10 mA collector current, a typical transition frequency (fT) of 250 MHz, and a power dissipation rating of 200 mW. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated base and emitter biasing resistors simplify circuit design
• Surface-mount SOT23 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 suffixes against official manufacturer documentation before ordering. Confirm that the specific revision of the datasheet matches the production batch requirements. Ensure compliance with RoHS and halogen-free specifications if required by the target application standards.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required in a compact SOT23 footprint. Verify that the 1 kΩ input resistor value aligns with the driving source impedance and desired input current levels. Ensure the -100 mA current limit and 200 mW power dissipation are sufficient for the intended load conditions.

Part Context

This part belongs to the DDTA(R1≠R2) Series CA family of 50V PNP pre-biased transistors. It is the complementary counterpart to the DDTC NPN series. The 'CA' designation indicates specific resistor tolerance and ratio characteristics defined in the datasheet. The '-7-F' suffix denotes reel packaging with 3,000 units per carrier.

Replacement Considerations

Direct substitutes within the same family include DDTA123YCA-7-F and DDTA143ZCA-7-F, provided their respective resistor values match the circuit requirements. Cross-manufacturer equivalents require verification of pinout compatibility and electrical parameter alignment.
