DDTA114EUA-7-F

Overview

The DDTA114EUA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 10 kΩ and R2 = 10 kΩ, resulting in a resistance ratio of 1. The device operates within a supply voltage range up to -50 V and supports a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. Packaged in a SOT-323 (SC-70) case, it offers a gain-bandwidth product of 250 MHz.

Feature Summary

• Integrates dual biasing resistors (R1 and R2) for simplified circuit design
• Utilizes epitaxial planar die construction for reliability
• Compliant with RoHS standards and lead-free plating specifications

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and reel specifications. Ensure that the component meets environmental compliance requirements such as RoHS and halogen-free status if mandated by the project constraints. Cross-reference the date code marking format to validate manufacturing timeline and material composition consistency.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter resistors is required. The SOT-323 package minimizes board space compared to through-hole alternatives. Verify that the -100 mA collector current rating aligns with the load requirements and that the thermal resistance characteristics are sufficient for the intended ambient temperature conditions.

Part Context

This part belongs to the DDTA1xxEUA series, which includes variants with different resistor values ranging from 2.2 kΩ to 100 kΩ. All members share the same SOT-323 footprint and electrical characteristics regarding voltage and current ratings, differing primarily in the internal resistor network configuration.

Replacement Considerations

Compatible substitutes include other PNP pre-biased transistors in the SOT-323 package with matching 10 kΩ/10 kΩ resistor ratios. Verify pinout compatibility and ensure equivalent DC current gain and saturation voltage parameters before implementation.
