2SC5200 is a high-power NPN bipolar junction transistor (BJT), widely used in audio amplifier output stages and other high-current switching applications. It is the complementary NPN pair to the 2SA1943 PNP transistor you asked about earlier.

📌 Key Specifications

• Type: NPN silicon BJT

• Package: TO-3P / TO-3PL (large through-hole power package)

• Collector–Emitter Voltage (Vᴄᴇo): 230 V typical (datasheet)

• Collector Current (Iᴄ): 15 A continuous, ~20 A pulse

• Power Dissipation (Pᴄ): 150 W (with proper heatsinking)

• DC Current Gain (hFE): 55–160 typical

• Transition Frequency (fT): ~30 MHz

• Operating Junction Temperature: –55 °C to +150 °C

📍 Typical Applications

• Audio power amplifier output stages — often in class AB designs

• Complementary push-pull stages (paired with 2SA1943)

• High-current switching and power circuits

• Power electronics where high voltage and high current are required

⚡ Notes

• Requires heatsinking due to high power dissipation

• Works in high-fidelity amplifier designs, industrial power drivers, and other high-current applications

• Often available as original Toshiba or equivalents/clones like TTA5200
