Overview
The DDTC114ECAQ-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors where R1 equals R2, with a nominal resistance of 10 kOhms each. The device is housed in a SOT-23 package and operates within a temperature range of -55°C to +150°C. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. It has a transition frequency of 250 MHz and meets AEC-Q101 automotive standards.
Feature Summary
- Epitaxial planar die construction for high reliability
- Built-in biasing resistors with equal values (R1 = R2)
- Qualified to AEC-Q101 standards for automotive applications
- Totally lead-free and fully RoHS compliant
Applications
- Automotive digital switching circuits
- General-purpose logic level translation
- High-reliability embedded control systems
Procurement Notes
Verify the component status before procurement as this specific part number is marked NRND (Not Recommended for New Design). Confirm that the ordering suffix 'Q' correctly denotes the AEC-Q101 qualified automotive variant. Ensure compatibility with existing PCB layouts designed for the SOT-23 footprint. Check for updated replacement recommendations from the manufacturer.
Selection Notes
Select this component when an NPN digital transistor with matched internal biasing resistors is required. The 10 kOhm resistor value suits standard logic interface applications. Verify that the 100 mA collector current and 50 V voltage ratings meet the circuit requirements. Consider the thermal characteristics and power dissipation limits for the intended operating environment.
Part Context
This component belongs to the DDTC (R1=R2 Series) CA family of NPN pre-biased transistors. It shares the same electrical and thermal characteristics as standard non-automotive versions but includes additional qualification for automotive use. The series offers various resistor values to accommodate different input drive requirements while maintaining a compact surface-mount form factor.
Replacement Considerations
The datasheet explicitly recommends using ADTC114ECAQ as the replacement for this NRND part number. Verify that the substitute maintains identical pinout, electrical parameters, and automotive qualification status.
