DDTA114EUA-7

Overview

The DDTA114EUA-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT-323 case with molded plastic material. The device integrates built-in biasing resistors where R1 equals R2, nominally 10 kOhms each. Maximum ratings include a supply voltage of -50 V and a power dissipation of 200 mW at 25°C ambient temperature. The DC current gain (hFE) has a minimum value of -30 under specific test conditions. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors with equal nominal values for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Housed in a compact SOT-323 surface mount package

Applications

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

Procurement Notes

Verify the exact ordering suffix against official documentation, as variations such as -7-F or -13-F indicate different reel quantities. Confirm RoHS compliance status and manufacturing date codes to ensure adherence to environmental regulations and material specifications required for the intended assembly process.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required in a SOT-323 footprint. Ensure the application voltage does not exceed the -50 V maximum rating. Consider the thermal resistance of 625 °C/W and derating curves if operating above 25°C ambient temperature to maintain safe junction temperatures.

Part Context

This part belongs to the DDTA1xxEUA series from Diodes Incorporated, which includes various resistor ratio options. The 'EUA' designation specifically refers to the SOT-323 package type. This series serves as a complement to NPN types like the DDTC114EUA, providing matched pairs for complementary circuit designs.
