The 2DA1774R-7-F is a high-performance PNP bipolar junction transistor (BJT) designed and manufactured by Diodes Incorporated, a leading company in the semiconductor market. This discrete semiconductor product is engineered to deliver efficient current control and amplification in a variety of electronic applications.

Key Features

• Transistor Polarity: PNP - This indicates that the transistor uses holes as its charge carriers, making it suitable for use in the negative side of the circuit or as a switch in high-side configurations.
• Collector-Emitter Voltage (VCEO): 45V - The maximum voltage that can be applied across the collector-emitter terminals without causing breakdown.
• Collector Current (IC): 150mA - The maximum continuous current that can flow through the collector of the transistor.
• Power Dissipation (Pd): 300mW - The amount of power the transistor can dissipate without exceeding its maximum operating temperature.
• DC Current Gain (hFE): 120 to 270 - A measure of the transistor's amplification capability, indicating the ratio of the output current to the input current in the active region.
• Operating Temperature Range: -55°C to +150°C - Ensures reliable performance across a wide range of environmental conditions.
• Mounting Type: Surface Mount - Designed for placement directly onto the surface of printed circuit boards (PCBs), saving space and allowing for automated assembly processes.
• Package / Case: SOT-23-3 - A small and popular package for transistors, providing a good balance between performance and compactness.
