C2655 transistor

Description

The C2655 is a medium-power NPN silicon transistor designed for both linear amplification and switching applications. It offers low saturation voltage, relatively fast switching characteristics, and moderate current capability, making it suitable for audio stages and general-purpose power control circuits.

Features

1. Low saturation voltage: VCE (sat) = 0.5 V (max) (IC = 1 A)

2. High collector power dissipation: PC = 900 mW

3. High-speed switching: tstg = 1.0 μs (typ.)

4. Complementary to 2SA1020.

Absolute maximum ratings ( Ta=25°C )

1. Collector to Base Voltage: Vcbo = 50 V

2. Collector to Emitter Voltage: Vceo = 50 V

3. Emitter to Base Voltage: Vebo = 5 V

4. Collector Current: Ic = 2A

5. Total Dissipation : Pc = 900 mW

6. Junction Temperature: Tj = 150°C

7. Storage Temperature: Tsg = -55 ~ +150°C

Design Notes (Critical Points)

Ensure adequate base drive for full saturation
Thermal dissipation is a major limitation (900mW max)
Use heat sinking or PCB copper area if operating near limits
Include flyback diode when driving inductive loads
Avoid operation near maximum ratings for reliability

Advantages vs MOSFET

Simpler drive requirements (no gate charge considerations)
Better linear behavior for analog amplification

Typical Applications

Audio power amplifier stages (driver/output stage)
Push-pull amplifier circuits
Relay drivers and inductive load switching
General-purpose power switching
Motor control (low power)

Alternative / Equivalent Products

2SC2655 (standard naming variant)
BD139 (higher power capability)
2N2222 (lower current applications)
2SC1815 (signal-level use)
