DDTA113TCA-7-F

Overview

The DDTA113TCA-7-F is a PNP pre-biased small-signal transistor manufactured by Diodes Incorporated. It utilizes epitaxial planar die construction and integrates a single built-in biasing resistor (R1) with a nominal value of 1 kΩ. The device is housed in an SOT23 surface-mount package, weighing approximately 0.008 grams. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (PD) of 200 mW at +25°C ambient temperature. The DC current transfer ratio (hFE) ranges from 100 to 600 under standard test conditions.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated R1-only biasing resistor simplifies circuit design
• Totally lead-free and fully RoHS compliant
• Halogen and antimony-free green device

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the component status remains active and matches the required packaging quantity. Ensure compliance with applicable environmental directives such as RoHS 2 and RoHS 3 during the purchasing process.

Selection Notes

Select this component when a PNP configuration with a 1 kΩ base resistor is required. Verify that the -50 V voltage rating and -100 mA current capacity meet the application's maximum operating limits. Consider the SOT23 package dimensions for PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the DDTA (R1-ONLY SERIES) CA family from Diodes Incorporated. It serves as the PNP counterpart to the DDTC NPN series. The product line offers various resistance values within the same SOT23 footprint to support diverse logic interface needs.

Replacement Considerations

Direct substitutes within the same series include DDTA123TCA-7-F, DDTA143TCA-7-F, and other variants listed in the ordering information table. Cross-manufacturer replacements require verification of pinout compatibility and electrical parameter equivalence.
