BSS138 MOSFET Overview

BSS138 MOSFETBSS138 MOSFET

The BSS138 is a compact N-Channel Mosfet Logic Level. The mosfet has a very low threshold voltage of 0.5V and can therefore be used with any low voltage application circuit and for level shifting applications. Adding to this, the Mosfet also has low on-state resistance and low input capability, which makes it efficient in switching circuits. Due to the compact nature of the mosfet, it is widely used in portable applications such as cell phones and other power management circuits.

The BSS138 is slightly expensive for its specification, so if you're looking for a cheap alternative, check 2N7002. However, with the on-state resistance and the Mosfet threshold voltage, you have to compensate slightly. This mosfet comes in an SMD package and can therefore be used for compact applications. A significant disadvantage of the mosfet is its low drain current; it can provide a continuous current of 200mA and peak currents of up to 1A at maximum threshold voltage. Anything more than that is going to damage the mosfet.


BSS138 MOSFET Applications

  • Low current and Low Voltage switching applications
  • Logic Level Shifters
  • DC-DC converts
  • eMobility applications
  • Application where low on-state resistance is required.
  • Power management applications

BSS138 MOSFET Package

The Mosfet is available in the SOT23 and TO-92 packages, the dimensions of the SOT23 package are shown below. Please refer to the BSS138 data sheet below for additional dimensions.
