QH8MB5 (New)
40V 4.5A/5.0A, Dual Nch+Pch, TSMT8, Power MOSFET

QH8MB5 is Nch + Pch dual MOSFET which supports 40V withstand voltage. This is designed for 24V input equipments such as factory automation equipments, and motors mounted on base stations (cooling fans). It contains ROHM's ultra-low on-resistance Nch / Pch MOSFETs in one package. By combining the optimum Nch + Pch, you can reduce the design efforts. It also contributes to lower power consumption of equipment.
