Overview
The DDTC114YCAQ-7-F is an NPN pre-biased small signal surface mount transistor from the DDTC (R1≠R2) CA series by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 47 kΩ. The device is qualified to AEC-Q101 standards for high reliability and automotive applications. 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 in an SOT-23 package. The DC current gain (hFE) has a minimum value of 68 at VO = 5V and IO = 5mA.
Feature Summary
- Integrated unequal biasing resistors (R1 ≠ R2) simplify circuit design by reducing component count.
- Qualified to AEC-Q101 standards for high reliability and PPAP capable for automotive use.
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green device construction.
Applications
- Automotive electronic systems requiring high reliability components.
- General-purpose switching applications utilizing pre-biased transistor configurations.
- Digital logic interface circuits where external biasing resistors are omitted.
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the 3,000-unit reel size on 7-inch tape with 8mm pitch. Confirm that the 'Q' designation indicates AEC-Q101 qualification and PPAP capability. Ensure the requested quantity matches the standard packaging unit to avoid partial reel handling issues.
Selection Notes
Select this part when an NPN digital transistor with a 10kΩ base resistor and 47kΩ emitter resistor is required. Compare against the non-automotive DDTC114YCA-7-F if AEC-Q101 qualification is not necessary. Verify that the 100mA collector current and 50V voltage ratings meet the application's load requirements.
Part Context
This component belongs to the DDTC114 family of pre-biased transistors. It shares the same electrical characteristics as other variants in the series but differs in internal resistor ratios and packaging options. The 'CA' suffix denotes the specific resistor configuration within the R1≠R2 product line.
Replacement Considerations
The DDTC114YCA-7-F is the standard commercial version with identical electrical specifications. Other Diodes Incorporated parts in the DDTC114 series may be used if different resistor ratios are acceptable.
FAQ
