DDTA114ECAQ-13-F

Overview

The DDTA114ECAQ-13-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT23 case. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 10kΩ. The device is qualified to AEC-Q101 standards for high reliability and is PPAP capable. Electrical characteristics include a supply voltage (VCC) of -50V, a maximum power dissipation (PD) of 200mW, and a DC current gain (hFE) minimum of 30 at VO = -5V and IO = -5mA. The operating temperature range spans from -55°C to +150°C.

Feature Summary

• Integrated equal-value biasing resistors simplify circuit design by reducing component count.
• Qualified to AEC-Q101 automotive standards ensuring high reliability and PPAP capability.
• Utilizes epitaxial planar die construction within a compact SOT23 package.

Applications

• General-purpose switching applications utilizing the integrated bias network.
• Interface circuits for logic-to-load interfacing in surface mount designs.

Procurement Notes

Verify the specific ordering suffix '-13-F' corresponds to the 10,000-unit reel size and 13mm tape width as defined in the manufacturer's ordering information table. Confirm that the 'Q' designation aligns with the required automotive qualification status, noting that this specific part number is listed as Not Recommended for New Design (NRND).

Selection Notes

Select this component when a PNP configuration with matched internal resistors is required for space-constrained PCB layouts. Ensure the application operates within the specified -50V supply limit and 200mW power dissipation constraints. Consider the NRND status when planning long-term production runs.

Part Context

This part belongs to the DDTA (R1=R2) CA series of PNP pre-biased transistors. It shares electrical characteristics with other variants in the series but differs in resistor values and packaging quantities. The 'CA' suffix indicates the specific resistor tolerance and marking code configuration for this product line.

Replacement Considerations

The datasheet explicitly recommends using ADTA114ECAQ as the substitute for this NRND part number. Verify that the replacement maintains the necessary AEC-Q101 qualification and PPAP requirements for your specific application context.
