Technical Specifications

The LMBT2907ADW1T1G transistor features a relatively high current gain (hFE), enabling efficient amplification in various circuit configurations. The saturation voltage (VCE(sat)) is generally low, which minimizes power loss when used as a switch. The transition frequency (fT) is typically in the MHz range, making it suitable for high-frequency applications. The operating temperature range usually spans from -55°C to +150°C. The datasheet also provides crucial parameters such as base-emitter saturation voltage (VBE(sat)), collector cutoff current (ICBO), and emitter cutoff current (IEBO). The SOT-363 package ensures efficient heat dissipation for its size.

The matched characteristics of the dual transistors make it an excellent choice for applications requiring symmetrical performance, such as differential amplifiers and current mirrors. The robust design and high current handling capability further enhance its reliability in demanding applications. The high hFE value allows this part to be controlled by low current microcontroller pins, reducing the need for additional current amplification hardware.
