BSS138 Description

Short technical summary and product information.

The Calogic LLC BSS138 is a versatile N-Channel MOSFET suitable for a wide range of electronic switching and amplification tasks. It offers a drain-source voltage (VDS) of up to 50V and can handle a continuous drain current (ID) of 300mA at a gate-source voltage (VGS) of 10V. The MOSFET exhibits a low on-resistance, with RDS(ON) typically less than 2.5Ω at VGS=10V and ID=500mA, and less than 3.5Ω at VGS=2.5V and ID=500mA. This makes it efficient for power management and signal switching circuits.

Key electrical characteristics include a gate threshold voltage (VGS(th)) ranging from 0.7V to 1.5V, and a forward transconductance (gFS) of 100mS. The device also has input capacitance (Ciss) of 50pF, output capacitance (Coss) of 25pF, and reverse transfer capacitance (Crss) of 8pF. It is rated for an ESD protection of 1.5KV HBM.

The BSS138 is housed in a compact SOT-23 surface-mount package, making it ideal for space-constrained designs. Its operating temperature range is from -55°C to 150°C, ensuring reliability in various environmental conditions. The thermal resistance junction-to-ambient is 417℃/W.
