DDTA114YE-7-F

Overview

The DDTA114YE-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates internal biasing resistors with nominal values of R1 = 10 kΩ and R2 = 47 kΩ. The device operates within a supply voltage range up to -50 V and supports a continuous collector current of -100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 68 at -10 mA, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW in the SOT-523 package. It functions across an operating temperature range from -55°C to +150°C.

Feature Summary

• Integrates two distinct biasing resistors (R1 ≠ R2) for simplified circuit design
• Qualified to AEC-Q101 standards for high reliability applications
• Utilizes epitaxial planar die construction for robust performance
• Compliant with RoHS directives and halogen/antimony-free green specifications

Applications

• Switching circuits requiring integrated base biasing
• Driver stages for low-power loads
• General-purpose digital logic interfacing

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm compliance with specific environmental regulations such as RoHS 3 and REACH requirements relevant to the target market. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines per J-STD-020 to prevent package damage during soldering processes.

Selection Notes

Select this variant when a PNP configuration with unequal biasing resistors (10kΩ input, 47kΩ emitter) is required. Compare against the DDTA114YUA-7-F if a different SOT-323 package or identical resistor ratios are needed. Verify that the 150 mW power dissipation limit in the SOT-523 case meets thermal constraints compared to higher power variants.

Part Context

This component belongs to the DDTA(R1≠R2 Series)E family, which provides various combinations of internal resistors for PNP transistors. It serves as a compact solution replacing discrete resistor networks, reducing board space and assembly steps. The 'E' suffix denotes the specific resistor ratio configuration within the broader DDTA product line.

Replacement Considerations

DDTA114YUA-7-F: Different package (SOT-323 vs SOT-523), same electrical parameters.
