BSS138LT1G Description

Short technical summary and product information.

The BSS138LT1G from On Semiconductor is an N-Channel power MOSFET designed for low-voltage applications. It offers a maximum drain-source voltage of 50V and a continuous drain current of 200mA at 25°C ambient temperature. The device features a low gate threshold voltage ranging from 0.85V to 1.5V, making it suitable for logic-level drive circuits. The maximum on-resistance is 3.5Ω at VGS=5V and ID=200mA.

 

Housed in a compact SOT-23-3 (TO-236) surface mount package, the BSS138LT1G saves board space and is supplied on tape and reel with 3000 units per reel. The device can dissipate up to 225mW and operates over a junction temperature range of -55°C to 150°C. The thermal resistance from junction to ambient is 556°C/W.

 

This MOSFET is RoHS3 compliant, Pb-Free, and Halogen Free, meeting current environmental standards. Typical applications include DC-DC converters, power management in portable and battery-powered products such as computers, printers, PCMCIA cards, cellular and cordless telephones. The low threshold voltage makes it ideal for low-voltage and battery-operated designs.
