BSS138 N-Channel Logic Level Enhancement Mode …

1 2005 Semiconductor Components Industries, LLC. September-2017, Rev. 3 Publication Order Number: BSS138 /DBSS138 N-Channel Logic Level Enhancement Mode field effect TransistorGeneral Description These N-Channel Enhancement mode field effect transistors are produced using ON Semicondcutor s proprietary, high cell density, DMOS technology. These products have been designed to minimize on-state resistance while provide rugged, reliable, and fast switching products are particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and other switching applications.

6 R JA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. R JC is guaranteed by design while R CA is determined by the user's board design. a) 350 C/W when mounted on a minimum Scale 1 : 1 on letter size paper 2.
