DDA114EK-7-F

Overview

The DDA114EK-7-F is a dual PNP pre-biased small signal transistor manufactured by Diodes Incorporated. It integrates two independent PNP transistors with built-in bias resistors in a single SOT-26 surface-mount package. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Typical base and emitter resistors are both 10 kOhms, resulting in a resistor ratio of 1. The minimum DC current gain (hFE) is specified at 30. Operating temperatures range from -55 °C to +150 °C, with a maximum power dissipation of 300 mW.

Feature Summary

• Dual configuration integrating two PNP transistors within a compact six-pin SOT-26 package.
• Built-in bias resistors simplify circuit design by reducing component count and board space.
• High thermal stability supports operation across an extended temperature range up to 150 °C.

Applications

• General-purpose switching applications requiring dual PNP logic interfaces.
• Driver circuits for low-power loads where space-constrained dual transistor solutions are needed.
• Signal level shifting or buffering in digital logic systems.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status through official datasheets or environmental reports before integration. Check for any product discontinuance notifications or end-of-life notices, as availability may be restricted. Ensure the supplier provides valid traceability documents matching the Diodes Incorporated part number.

Selection Notes

Select this component when a dual PNP pre-biased solution is required in a SOT-26 footprint. Compare the 10 kOhm typical resistor values against circuit requirements to ensure proper base drive currents. Verify that the 50 V collector-emitter voltage rating exceeds the maximum operating voltage in the target application. Consider the 100 mA continuous current limit for load handling capabilities.

Part Context

This part belongs to the DDA114 series of dual PNP pre-biased transistors from Diodes Incorporated. Variants such as DDA114EH-7 offer similar electrical characteristics but utilize different packages like SOT-563. The DDA114EK-7-F specifically denotes the SOT-26 package configuration with standard 10 kOhm biasing resistors.

Replacement Considerations

Direct pin-compatible alternatives include the DDA114EH-7, which shares identical electrical parameters but uses an SOT-563 package. Other family members like DDTA114EUA-7-F provide single-transistor configurations in smaller packages. Verify package dimensions and pinout compatibility before substitution.
