DDTC115TKA-7-F

Overview

The DDTC115TKA-7-F is an NPN pre-biased small signal surface mount transistor from the DDTC (R1-only series) by Diodes Incorporated. It features epitaxial planar die construction with a built-in biasing resistor R1 of 100 kOhms nominal value. The device operates within a collector-emitter voltage range up to 50 V and supports a continuous collector current of 100 mA, with a power dissipation rating of 200 mW at 25°C ambient temperature. It utilizes the SC-59 package and offers a DC current transfer ratio (hFE) ranging from 100 to 600 under standard test conditions.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated single biasing resistor simplifies circuit design
• Lead-free and RoHS compliant manufacturing process

Applications

• General-purpose switching applications
