DDTA114ECA-7

Overview

The DDTA114ECA-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction in a SOT23 package. The device integrates built-in biasing resistors where R1 equals R2, with a nominal resistance of 10 kΩ. Key electrical parameters include a maximum supply voltage (VCC) 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 gain (hFE) has a minimum value of 30, and the transition frequency (fT) is typically 250 MHz. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual biasing resistors with equal nominal values for simplified circuit design
• Constructed using epitaxial planar die technology for reliability
• Qualified to AEC-Q101 standards for high-reliability automotive applications
• Compliant with RoHS directives and free from halogen and antimony

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• General-purpose switching applications utilizing single PNP configuration
• Interface circuits replacing discrete resistor-transistor networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm status and packaging details. The datasheet lists the -7-F variant as active; ensure the requested part number matches the exact suffix required for your manufacturing process. Confirm compliance requirements such as PPAP capability if intended for automotive assembly lines. Check for any product change notifications that may affect lead times or material composition before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with matched internal resistors is required. The 10 kΩ resistor value suits standard logic interface levels. Ensure the application voltage does not exceed the -50 V collector-emitter rating. Consider the thermal resistance of 625 °C/W when designing PCB layouts, as power dissipation is limited to 200 mW. Verify that the SOT23 package dimensions fit the available board space constraints.

Part Context

This component belongs to the DDTA series of PNP pre-biased transistors from Diodes Incorporated. It is part of the R1=R2 subgroup, distinguishing it from ratios like 1:10 or 1:100 found in other variants. The series offers complementary NPN types under the DDTC designation. This specific model provides a standardized 10 kΩ resistance configuration suitable for general-purpose digital switching tasks.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Designers should evaluate other DDTA series members with similar resistance values or consult manufacturer cross-reference guides for electrically equivalent parts.
