DDTA114YCA-7-F

Overview

The DDTA114YCA-7-F is a single PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 surface-mount package. It integrates internal biasing resistors with values of R1 = 10 kΩ and R2 = 47 kΩ. The device supports a maximum supply voltage (VCC) of -50 V and a continuous collector current (IC) of -100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 68 and a transition frequency (fT) of 250 MHz. Thermal performance allows for a power dissipation of 200 mW and operation within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design and reduce component count.
• Utilizes epitaxial planar die construction for reliable semiconductor performance.
• Designed for automated assembly using a compact surface-mount SOT23 package.

Applications

• General-purpose switching applications requiring integrated base drive.
• Driver circuits for logic interfaces or low-power loads.
• Complementary configurations utilizing the corresponding NPN DDTC series.

Procurement Notes

Verify the specific ordering suffix '-7-F' against official manufacturer documentation to confirm packaging details and compliance status. Ensure that the required resistor ratio matches the application needs, as this part number corresponds to a fixed 10kΩ/47kΩ configuration. Confirm RoHS and halogen-free status requirements align with project specifications before finalizing procurement.

Selection Notes

Select this component when a PNP digital transistor with a 10kΩ base resistor and 47kΩ emitter resistor is required. Verify that the -50V supply rating and -100mA current capacity meet the load requirements. Consider the SOT23 package dimensions for PCB layout constraints and ensure thermal management accommodates the 200mW power dissipation limit under operating conditions.

Part Context

This component belongs to the DDTA(R1≠R2) Series CA family from Diodes Incorporated. It represents a specific variant within the broader lineup of pre-biased transistors, distinguished by its unique internal resistor network. The 'CA' designation indicates the SOT23 package style, differentiating it from other packages like SOT-323 or SOT-523 found in related product codes.

Replacement Considerations

Direct functional substitutes within the same series include DDTA114WCA-7-F, which shares the same package but features different internal resistor values (10kΩ/4.7kΩ). Other variants such as DDTA123YCA-7-F or DDTA143ZCA-7-F offer alternative resistance ratios while maintaining identical electrical ratings and package form factors.
