Leadless MOSFET Cuts Footprint And Thermal Resistance

Claiming a PCB footprint 50% smaller than industry standard SOT23 devices and a thermal resistance 40% lower than comparable MOSFETs, the ZXMN2F34MA leadless MOSFET measures 2 mm x 2 mm in a DFN322 package with an off-board height of 0.85 mm. Rated at 20V, its low thermal resistance promises cooler operation and higher power density. At typical gate source voltages of 4.5V and 2.5V, the respective on-resistance values are 60 m? and 120 m?. Additionally, a low reverse recovery charge reduces switching losses and EMI problems. Price for the ZXMN2F34MA is $0.10 each/10,000. ZETEX INC., Hauppauge, NY. (631) 360-2222.
