Package : TO-247 Type

Manufacturer: Multicomp


TIP3055 datasheet



Silicon Power NPN Transistor is designed for use in general purpose power amplifier and switching applications.


• Power Dissipation-PD= 90W at TC= 25°C.

• DC Current Gain hFE = 20 ~ 100 at IC= 4.0A.

• VCE(sat) = 1.1V (Maximum) at IC= 4.0A, IB= 400mA.

Advantages Vs Disadvantages


1. High gain and low saturation voltage: High current gain and low saturation voltage, which makes it suitable for use in high-power amplifiers and switching circuits.

2. Robust and durable: The TO-247 package provides mechanical strength and better heat dissipation, making it suitable for use in harsh environments.


1. Heat dissipation: Generate a significant amount of heat during operation, which may require additional cooling measures.

2. Limited voltage and current ratings: limits its use in high-power applications.

3. Low-frequency response: It is not suitable for use in high-frequency circuits as it has a low frequency response.

Absolute maximum ratings ( Ta=25°C )

1. Collector to Base Voltage: Vcbo = 100 V

2. Collector to Emitter Voltage: Vceo = 60 V

3. Emitter to Base Voltage: Vebo = 7 V

4. Collector Current: Ic = 15 A

5. Collector Dissipation: Pc = 90 W

6. Junction Temperature: Tj = 150°C

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