Overview
The DDTC123YCA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 10 kΩ. The device operates within a supply voltage (VCC) range up to 50 V and supports a continuous collector current (IO) of 100 mA. Power dissipation is rated at 200 mW, with a thermal resistance (RθJA) of 625 °C/W. The component functions across an operating and storage temperature range of -55°C to +150°C. It utilizes an SOT-23 package and meets AEC-Q101 standards for high reliability.
Feature Summary
- Epitaxial planar die construction
- Built-in biasing resistors (R1 ≠ R2)
- Qualified to AEC-Q101 standards for high reliability
- Totally lead-free and fully RoHS compliant
Applications
- Inverter circuits without external input resistors
- Switching applications requiring integrated biasing
- Automotive electronics due to AEC-Q101 qualification
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the 3,000-unit reel size and standard marking code 'N05'. Confirm compliance requirements such as RoHS and halogen-free status against project specifications. Ensure the application environment remains within the specified -55°C to +150°C temperature range. Check for any end-of-life notices or alternative sourcing options if long-term availability is required.
Selection Notes
Select this component when an NPN digital transistor with a 2.2 kΩ base resistor and 10 kΩ emitter-base resistor is required. It is suitable for designs needing a single-supply configuration with integrated biasing to simplify circuit layout. Consider the 100 mA output current limit and 50 V breakdown voltage for load compatibility. Verify that the SOT-23 package dimensions fit the PCB footprint constraints.
Part Context
This part belongs to the DDTC (R1≠R2 Series) CA family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor, offering complementary PNP types in the DDTA series. The 'CA' designation indicates the specific resistor ratio and packaging type. It is distinct from other variants like DDTC123JCA which feature different resistor values.
Replacement Considerations
DDTC123JCA-7-F: Features different resistor values (R1=2.2kΩ, R2=47kΩ).
