SMMBTA13LT1G Description

Short technical summary and product information.

The SMMBTA13LT1G is an NPN Silicon Darlington amplifier transistor manufactured by On Semiconductor. It is designed for applications requiring high current gain, with a DC current gain (hFE) of 10000 at 100mA and 5V. The device can handle a continuous collector current of up to 300mA and has a collector-emitter voltage rating of 30V.

 

This transistor operates within a wide temperature range of -55°C to 150°C. It is supplied in a compact SOT-23-3 (TO-236) surface-mount package, making it suitable for space-constrained designs. The device is Pb-Free and Halogen Free, adhering to modern environmental standards.

 

Key electrical characteristics include a Vce saturation voltage of 1.5V at 100µA/100mA and a frequency capability of 125MHz. The total device dissipation is rated at 225 mW on an FR-5 board at 25°C.
