onsemi Small Signal NPN Transistor 500 mA 80 V DC 3-Pin SOT-23 MMBT8099LT1G

The onsemi MMBT8099LT1G is a small signal NPN transistor optimized for applications requiring moderate current handling and reliable switching capability. It supports a maximum DC collector current of 500 mA and a collector-emitter voltage rating of 80 V DC, making it well suited for electronic circuits in industrial, consumer electronics, and automotive domains.

Housed in a compact 3-pin SOT-23 surface mount package, this transistor facilitates high-density PCB designs, especially where space constraints are critical. Its transistor configuration is a single NPN type, providing a minimum DC current gain (hFE) of 75, which ensures good amplification in low power analog switching circuits.

With a maximum power dissipation rating of 225 mW and a transition frequency (ft) of 100 MHz, the MMBT8099LT1G can operate efficiently in high-speed switching and signal processing applications. It maintains stable operation over a wide temperature range from -55°C to 150°C, making it suitable for harsh environmental conditions typically found in industrial and automotive electronics.

Electrical limits include a maximum collector-base voltage of 80 V and an emitter-base voltage of 6 V, ensuring robust switching and protection against voltage spikes. The physical package dimensions are approximately 3.04 mm in length, 1.4 mm in width, and 1.01 mm in height, allowing integration into tight electronic assemblies.

While no specific approvals or automotive standards are certified for this model, its quality and reliability meet the demands of general-purpose bipolar transistor applications. The MMBT8099LT1G is widely used in power management, signal amplification, and electronic switching roles across industrial, laboratory, and commercial electronic devices.
