Description

The MMBTA92LT1G is a high-voltage PNP bipolar junction transistor (BJT) from onsemi, designed for switching and linear amplification applications requiring substantial voltage capability in a compact surface-mount package. Housed in the industry-standard SOT-23, this device offers a collector-emitter voltage (VCEO) of 300V and continuous collector current of 500mA. It features low saturation voltage and fast switching characteristics, making it suitable for high-voltage signal processing, telecom circuits, and industrial controls. The MMBTA92LT1G is the PNP complement to the popular MMBTA42LT1G NPN transistor. With its small footprint, high voltage rating, and lead-free (RoHS-compliant) construction, it is ideal for space-constrained designs where through-hole TO-92 parts are impractical.
