DDTA114EE-7-F

Overview

The DDTA114EE-7-F is a single PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT523 surface-mount package. It integrates two equal biasing resistors (R1 = R2) with a nominal value of 10 kΩ each. The device features a supply voltage rating of 50 V and supports a maximum continuous collector current of -100 mA. Electrical characteristics include a minimum DC current gain (hFE) of -30 at a collector current of -5 mA, and a transition frequency (fT) of 250 MHz. Thermal performance specifies a power dissipation of 150 mW and a junction-to-ambient thermal resistance of 833 °C/W. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual biasing resistors with equal nominal values to simplify circuit design
• Utilizes epitaxial planar die construction for high reliability
• Compliant with RoHS directives and halogen-free manufacturing standards

Applications

• General-purpose switching applications requiring integrated base drive
• Driver circuits for low-power loads or logic level translation
• Automotive electronics systems meeting specific quality control requirements

Procurement Notes

Verify the ordering suffix against official manufacturer documentation to confirm packaging specifications. Confirm that the requested quantity aligns with standard reel sizes. Ensure compliance with relevant environmental regulations such as RoHS and REACH before finalizing procurement orders.

Selection Notes

Select this component when a single PNP transistor with integrated 10 kΩ biasing resistors is required. Verify that the SOT523 package dimensions fit the available PCB space. Ensure the operating voltage does not exceed the 50 V limit and that thermal constraints are managed within the specified power dissipation ratings.

Part Context

This part belongs to the DDTA114EE series of pre-biased transistors from Diodes Incorporated. It shares the same electrical topology as other members of the EE family but differs in resistor values. The device is designed for compact surface-mount applications where board space is limited and simplified biasing networks are preferred over discrete resistor configurations.

Replacement Considerations

Direct replacements must match the SOT523 package, PNP polarity, and 10 kΩ internal resistor configuration. Verify that alternative components meet the 50 V supply voltage and -100 mA current requirements. Check thermal resistance and gain specifications to ensure equivalent performance in the target application.
