PNP Transistor 8550 (Pack of 10 pcs)

The 8550 is a PNP bipolar junction transistor (BJT) commonly used in electronic circuits for switching and amplification purposes. It’s often found in applications like audio amplification, switching circuits, and as part of H-Bridge motor drivers.

Key Specifications:

• Type: PNP BJT
• Collector-Emitter Voltage (Vce): -40V (max)
• Collector Current (Ic): -1A (max)
• Power Dissipation (P): 40W (typical with proper cooling)
• Gain (hFE): 40–320 (depends on the model and operating conditions)
• Package: Typically in TO-220 or TO-92 for easy mounting.

Working Principle: Since it’s a PNP transistor:

• Current Flow: The current flows from the emitter (E) to the collector (C) when the base (B) is at a lower potential than the emitter.
• Turn-On Condition: The transistor conducts when the base-emitter voltage (V_BE) is negative (typically around -0.7V for silicon BJTs).
