The ST1NK80ZT4 MOSFET is a N-channel SuperMESH power MOSFET manufactured by STMicroelectronics. It has an 800V drain-to-source breakdown voltage and a 13ohm on-resistance max RDS(ON). Its continuous drain current is 1A and it has a gate-threshold voltage of 2.2V max. This part is recommended for audio, telecom and portable applications. Its integrated Zener diode provides an effective protection for the drain-source junction against electrostatic discharge (ESD). It has a higher power handling capability and lower gate charge than its conventional counterparts.
