DDTA114ECAQ-7-F

Overview

The DDTA114ECAQ-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT23 package. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 10 kΩ. The device is qualified to AEC-Q101 standards for high reliability and is PPAP capable. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V, a continuous collector current of -100 mA, and a power dissipation of 200 mW. The DC current gain (hFE) has a minimum value of 30, and the transition frequency (fT) is typically 250 MHz.

Feature Summary

• Integrated equal-value biasing resistors simplify circuit design by reducing component count.
• Qualified to AEC-Q101 automotive standards with PPAP capability for high-reliability applications.
• Utilizes epitaxial planar die construction for robust performance.
• Compliant with RoHS directives and manufactured as a halogen- and antimony-free green device.

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components.
• General-purpose switching applications utilizing single NPN/PNP configurations.
• Driver circuits for relays, solenoids, or LEDs where integrated biasing is beneficial.

Procurement Notes

Verify that the specific ordering suffix matches the required packaging quantity and reel size. Confirm compliance with RoHS and lead-free requirements if mandated by the project specifications. Ensure the component status is acceptable for new designs, noting that some variants may carry Not Recommended for New Design (NRND) status.

Selection Notes

Select this part when a PNP digital transistor with matched internal resistors is needed. Verify that the 10 kΩ resistor value aligns with the drive source capabilities. Check that the -50 V voltage rating and -100 mA current limits exceed the application's peak requirements. Consider the SOT23 package dimensions for PCB layout constraints.

Part Context

This component belongs to the DDTA(R1=R2)CA series of pre-biased transistors. It serves as the PNP counterpart to the DDTC(NPN) series. The 'Q' suffix indicates automotive qualification under AEC-Q101 standards. It is electrically equivalent to standard commercial versions but meets stricter automotive reliability criteria.

Replacement Considerations

The datasheet explicitly recommends using ADTA114ECAQ as a replacement for NRND automotive variants. Standard commercial equivalents like DDTA114ECA-7-F are electrically identical but lack automotive qualification. Verify package compatibility and pinout alignment before substitution.
