TIP33CG

TIP33CG Description

The TIP33CG from onsemi is a high-performance NPN bipolar power transistor designed for demanding switching and amplification applications. Packaged in a robust TO-247-3 through-hole format, it offers a collector-emitter breakdown voltage (Vce) of 100V and a maximum collector current (Ic) of 10A, making it suitable for medium-to-high power circuits. With a transition frequency of 3MHz, it balances speed and power efficiency, while its low collector cutoff current (700µA) ensures minimal leakage in standby modes. The device is RoHS3 compliant and REACH unaffected, meeting modern environmental standards.

TIP33CG Features

• High Voltage & Current Handling: Supports 100V Vce and 10A Ic, ideal for power regulation and motor control.
• Low Saturation Voltage: 4V @ 2.5A base current (Ib) and 10A Ic, reducing power losses in switching applications.
• High Power Dissipation: 80W maximum power rating ensures reliability under heavy loads.
• DC Current Gain (hFE): Minimum 20 @ 3A Ic and 4V Vce, providing stable amplification.
• Robust Packaging: TO-247-3 through-hole design enhances thermal management and mechanical durability.
• Environmental Compliance: ROHS3 and REACH certified, with MSL Not Applicable for easier storage and handling.
