The SMMBTA56WT3G is a high-performance PNP bipolar junction transistor (BJT) from ON Semiconductor, a leading provider in the electronic components industry. This semiconductor device is designed for general-purpose amplifier and switching applications, offering a blend of reliability and efficiency in a compact SOT-323 package.

Key Features:

• Transistor Polarity: PNP - This means the transistor allows the flow of electrons from its emitter to collector and is primarily used for amplification and switching with a positive polarity signal.
• Collector-Emitter Voltage (VCEO): 80V - This rating indicates the maximum voltage the transistor can withstand across the collector-emitter terminals when the base terminal is open.
• Collector Current (IC): 500 mA - The maximum continuous current that can flow through the collector of the transistor, making it suitable for moderate power applications.
• Power Dissipation (Pd): 225 mW - The maximum power that the transistor can dissipate without exceeding its maximum operating temperature, ensuring stable performance during operation.
• DC Current Gain (hFE): 100 to 250 - This parameter indicates the transistor's ability to amplify the input signal, with a minimum gain of 100, making it an effective choice for amplification purposes.
• Package / Case: SOT-323 - A small and lightweight surface-mount package that allows for high-density mounting and is suitable for automated assembly processes.
• Moisture Sensitivity Level (MSL): 1 - This rating ensures that the device has a low sensitivity to moisture, providing reliability in various environmental conditions.
• RoHS Compliant: Yes - The SMMBTA56WT3G adheres to the Restriction of Hazardous Substances Directive, making it environmentally friendly and safe for use in electronic equipment.
