ADTC124ECAQ-7

ADTC124ECAQ-7 is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated. It integrates built-in bias resistors (R1 = R2 = 22 kΩ) which reduces component count and simplifies circuit design. The transistor is rated for a collector-emitter breakdown voltage of 50 V and a collector current of 100 mA. Power dissipation is 310 mW with a transition frequency of 250 MHz, making it suitable for switching and amplification applications.

The device is qualified to AEC-Q101 standards for automotive applications and is fully RoHS3 compliant. It is also lead-free and halogen-free, meeting modern environmental requirements. The operating temperature range is -55°C to +150°C, and the thermal resistance from junction to ambient is 403 °C/W. The input voltage range is -10 V to +40 V, and the output current is 30 mA.

The ADTC124ECAQ-7 is housed in a SOT-23 package with a gull-wing lead style and matte tin plated leads. It is available in tape and reel packaging with a standard quantity of 3,000 pieces per reel (7-inch reel, 8 mm tape width). The package is moisture sensitivity level 1 (MSL 1) per J-STD-020, allowing unlimited floor life.

This transistor is ideal for space-constrained designs where bias resistors are needed. The built-in resistors eliminate the need for external components, improving reliability and reducing board space. It is commonly used in automotive electronics, consumer devices, and industrial control systems.
