JA101Q Transistor PNP 50V 100mA  500mW TO-92 Original Philips

The JA101Q is a PNP type bipolar junction transistor (BJT) designed for general-purpose low-power switching and amplification tasks. Manufactured originally by Philips, it comes in a compact TO-92 plastic package and is suitable for signal processing, small-signal amplification, and low-current switching applications. 

Key Features:

• Type: PNP Bipolar Transistor
• Maximum Collector-Emitter Voltage (Vceo): 50V
• Maximum Collector Current (Ic): 100mA
• Maximum Power Dissipation (Ptot): 500mW (0.5W)
• DC Current Gain (hFE): Typically 100 - 300 (depending on operating conditions)
• Package Type: TO-92
• Operating Temperature Range: -65°C ~ +150°C
• Transition Frequency (ft): Around 150 MHz (typical) 

Applications:

• General-purpose amplification
• Low-power switching circuits
• Signal processing in audio or RF circuits
• Driver stages for small loads 

Notes:

• Since it's a PNP transistor, current flows from emitter to collector (when base is more negative than emitter).
• It is especially suitable for compact, low-power, and high-frequency applications.
