2N3055AG

2N3055AG Description

The 2N3055AG from onsemi is a high-performance NPN bipolar junction transistor (BJT) designed for robust power amplification and switching applications. Housed in a TO-204 (TO-3) package, it delivers a maximum collector current (Ic) of 15A and a collector-emitter voltage (Vce) rating of 60V, making it suitable for medium-to-high power circuits. With a transition frequency of 6MHz, it balances speed and power efficiency, while its low collector cutoff current (700µA max) ensures minimal leakage in standby modes. The transistor boasts a high DC current gain (hFE ≥ 10 @ 4A, 2V), ensuring reliable amplification even under heavy loads.

2N3055AG Features

• High Power Handling: Supports up to 115W of power dissipation, ideal for demanding applications.
