DDTA144ECAQ-13-F

Overview

The DDTA144ECAQ-13-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 47 kΩ and R2 = 47 kΩ, resulting in a resistance ratio of 1. The device is housed in an SOT-23 package and supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. It has a power dissipation rating of 200 mW at +25°C ambient temperature and operates within a temperature range of -55°C to +150°C. The component is qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• Epitaxial planar die construction with integrated base and emitter biasing resistors
• Qualified to AEC-Q101 standards for high reliability and PPAP capable
• Totally lead-free and fully RoHS compliant with halogen and antimony free green device characteristics

Applications

• Automotive electronic circuits requiring AEC-Q101 qualification
• General purpose switching applications utilizing the pre-biased configuration
• Surface mount assembly processes compatible with SOT-23 packaging

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance status and packaging details. The datasheet indicates that the DDTA144ECAQ-13-F part number is listed as Not Recommended for New Design (NRND). Confirm availability and potential obsolescence risks before finalizing procurement plans. Ensure all regulatory requirements such as RoHS and PPAP are met for the intended application environment.

Selection Notes

Select this component when a PNP pre-biased transistor with 47 kΩ internal resistors is required for space-constrained designs. The SOT-23 package offers a compact footprint suitable for automated surface mount assembly. Consider the NRND status when designing new products; evaluate alternative active parts or the recommended ADTA144ECAQ series if long-term supply stability is a priority. Verify thermal performance under actual operating conditions given the 200 mW dissipation limit.

Part Context

This component belongs to the DDTA (R1 = R2 Series) CA family from Diodes Incorporated, which provides complementary NPN types in the DDTC series. The DDTA144 variant specifically denotes the 47 kΩ resistor configuration within this lineup. The 'Q' suffix typically indicates automotive qualification, while the '-13-F' suffix relates to tape and reel packaging specifications for higher volume manufacturing.

Replacement Considerations

The datasheet explicitly recommends using the ADTA144ECAQ part instead of the DDTA144ECAQ-13-F due to its NRND status. Electrically and thermally, automotive and standard products are identical unless specified otherwise. Verify pinout compatibility and electrical parameters when transitioning to the ADTA series or other equivalent pre-biased transistors.
