DDTA123YCA-7

Overview

The DDTA123YCA-7 is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It integrates internal biasing resistors with R1 at 2.2 kΩ and R2 at 10 kΩ. The device supports a maximum supply voltage of -50 V and a continuous collector current of -100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 33 and a transition frequency 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

• Epitaxial planar die construction for reliable semiconductor performance
• Integrated biasing resistors eliminate the need for external input components
• Surface-mount SOT-23 package optimized for automated assembly processes
• Fully RoHS compliant and halogen-free green device manufacturing

Applications

• General-purpose switching circuits requiring integrated biasing
• Driver stages for low-power loads in consumer electronics
• Signal inversion applications utilizing built-in resistor networks

Procurement Notes

Verify the specific ordering suffix against official distributor catalogs to ensure correct packaging configuration. Confirm that the component meets required environmental standards such as RoHS compliance before finalizing procurement orders. Cross-reference datasheet revision numbers to guarantee compatibility with existing design specifications.

Selection Notes

Select this component when a PNP logic interface requires simplified circuit topology through integrated biasing. Ensure the application voltage does not exceed the -50 V rating and current demands remain within the -100 mA limit. Verify thermal management requirements align with the 200 mW power dissipation capability in the target enclosure.
