MMBTA92LT3G

MMBTA92LT3G Description

The MMBTA92LT3G from onsemi is a high-voltage PNP bipolar junction transistor (BJT) designed for surface-mount applications. Packaged in a compact SOT-23-3 form factor, it offers a robust 300V collector-emitter breakdown voltage (V_CEO) and a 500mA continuous collector current (I_C), making it suitable for demanding switching and amplification tasks. With a 50MHz transition frequency (f_T), it balances speed and power efficiency, while its low V_CE(sat) of 500mV (at 2mA I_B, 20mA I_C) ensures minimal power loss in saturated operation. Compliant with ROHS3 and REACH standards, it meets stringent environmental and safety requirements.
