DDTA113ZUA-7-F

Overview

The DDTA113ZUA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction in a SOT-323 package with built-in biasing resistors R1 and R2, where R1 is nominally 1 kΩ and R2 is nominally 10 kΩ. The device supports a supply voltage of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with a junction-to-ambient thermal resistance of 625 °C/W. The gain-bandwidth product is 250 MHz, and the operating temperature range spans from -55°C to +150°C.

Feature Summary

• Integrates internal biasing resistors (R1≠R2) to simplify circuit design
• Utilizes epitaxial planar die construction for reliability
• Available in a compact SOT-323 surface mount case

Applications

• General-purpose switching applications
• Driver circuits requiring integrated biasing
• Low-power digital logic interfacing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and date code markings against the latest datasheet specifications. Ensure storage conditions adhere to moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component for designs requiring a PNP pre-biased transistor with specific 1kΩ/10kΩ resistor ratios. Compare electrical characteristics such as DC current gain and saturation voltage against alternative NPN counterparts like the DDTC series if polarity requirements differ.

Part Context

This part belongs to the DDTA (R1≠R2 Series) UA family of pre-biased transistors. It serves as the PNP complement to the DDTC series NPN devices. The 'UA' suffix indicates the SOT-323 package type, while the '7-F' suffix denotes tape and reel packaging compliant with lead-free manufacturing standards.

Replacement Considerations

Direct substitutes within the same family include other DDTA variants with different resistor values but identical SOT-323 packaging. For NPN polarity requirements, the corresponding DDTC series devices are available.
