Overview
The DDTA114ECA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-23 package. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 10 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with a DC current gain (hFE) minimum of 30. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Integrated dual biasing resistors simplify circuit design by eliminating external components.
- Qualified to AEC-Q101 standards for high reliability in automotive applications.
- Epitaxial planar die construction ensures stable performance across wide temperature ranges.
Applications
- Automotive electronic systems requiring AEC-Q101 qualified components.
- General-purpose switching circuits utilizing pre-biased logic interfaces.
- Driver stages for low-power loads where simplified biasing is required.
Procurement Notes
Verify the specific ordering suffix to confirm compliance status. The '-7-F' suffix indicates standard RoHS compliance and lead-free construction. Confirm that the 'CA' variant matches the required electrical specifications for the target application. Ensure packaging details align with production requirements.
Selection Notes
Select this component when a PNP digital transistor with 10 kΩ internal biasing resistors is needed. Compare against the DDTB series if higher current handling is required. Verify that the SOT-23 footprint fits the PCB layout constraints. Check thermal derating curves if operating near maximum power limits.
Part Context
This part belongs to the DDTA (R1=R2) CA series of pre-biased transistors. It complements the DDTC NPN series for push-pull configurations. The 'CA' designation specifies the SOT-23 case style and resistor tolerance characteristics defined in the datasheet.
Replacement Considerations
The datasheet notes that the DDTA114ECAQ-7-F is Not Recommended for New Design (NRND) and suggests using ADTA114ECAQ as the alternative. Other variants in the series differ only in resistor values or polarity.
