What is MOSFET N-CH 30V 14A/35A 8PQFN

The metal oxide semiconductor field effect transistor (MOSFET) N-CH 30V 14A/35A 8PQFN is a type of semiconductor used as a switch in electronic circuits. N-CH indicates that the device is able to manage negative charges because the “N” speaks for the polarity of the device, which is N-Channel. The designation “30V” in the product’s name implies that the MOSFET’s operating voltage range is up to 30 volts from drain to source.

Maximum drain currents of 14A (when the device runs at a defined temperature) and 35A (when the device operates at its rated temperature) are indicated by the 14A and 35A values, respectively (when the device is in a pulsed state). The “8PQFN” in the product’s name indicates a surface-mount package with eight pins in a quad-flat configuration and no leads.

This MOSFET kind finds widespread use as low-side switches in power-over-line DC/DC converters, secondary-side synchronous rectifiers, and ORing FET/load switches, among many other places. These MOSFETs have low on-state resistance (rDS(on)) and great switching performance; they were made specifically to reduce power conversion losses. They are safe for the environment because of their sturdy packaging and conformity with the RoHS directive on restricting the use of certain hazardous materials.

The electrical parameters of the MOSFET N-CH 30V 14A/35A 8PQFN include a threshold voltage of 1.0-3.0 volts and a static drain-to-source on resistance of 5.5-11.0 milliOhms, both of which vary with gate-to-source voltage and drain current. Additionally, the input capacitance of the device ranges from 1195-1590 pF, and the forward transconductance is 72 Siemens. Between 18 and 26 nC of gate charge are needed to switch on the device; however, this varies widely with gate voltage and drain current. This device utilizes a drain-source diode with forward voltage characteristics of 0.8–1.2 volts and a reverse recovery time of 27–44 ns.

The N-CH 30V 14A/35A 8PQFN MOSFET, in general, is a high-performance power MOSFET that can be used in various power conversion settings. Its excellent efficiency and low on-state resistance make it a practical and trustworthy choice for power management in a wide range of electronic devices.
