DDTA123YCA-7-F

Overview

The DDTA123YCA-7-F is a PNP pre-biased transistor from Diodes Incorporated, housed in an SOT-23 surface-mount package. It integrates internal biasing resistors with nominal values of R1 = 2.2 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 an operating temperature range spanning from -55°C to +150°C. The component features a minimum DC current gain (hFE) of 33 and a transition frequency (fT) of 250 MHz.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. Confirm RoHS compliance status through authorized channels prior to procurement. Ensure that the selected variant matches the required resistor tolerance specifications for the intended application environment.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required. Verify that the 2.2 kΩ input resistance aligns with the driving source capabilities. Check thermal constraints to ensure power dissipation remains within the 200 mW limit under worst-case operating conditions.

Part Context

This part belongs to the DDTA(R1≠R2) Series CA family, which offers various combinations of internal resistors. It serves as the PNP counterpart to the DDTC NPN series. The 'CA' designation indicates the specific resistor ratio and package type used across this product line.

Replacement Considerations

Direct functional substitutes include other DDTA123 variants such as DDTA123JCA or DDTA123ZCA, provided their specific resistor values match the circuit requirements. Cross-reference electrical parameters like hFE and VCEO before substitution.
