NettetTwo tolerance series: ±2 % and approximately ±5 %. Wide working voltage range: nominal 2.4 V to 75 V (E24 range) Small plastic package suitable for surface-mounted design. Low differential resistance. Qualified according to AEC-Q101 and recommended for use in automotive applications. Nettet1Davide • 6 yr. ago. The 2 MOSFETs are connected in "anti-series". It takes two MOSFETs to form a bi-directional switch, one to control current in one direction, the other one for the other direction. If you had only one MOSFET, you would get a uni-directional switch: you could only be able to control current in one direction.
