Description

The IXZ4DF18N50 is a CMOS high speed high current gate driver and ZMOS MOSFET combination

specifically designed Class D and E HF RF applications at up to 40MHz, as well as other applications. The

IXZ4DF18N50 in pulse mode can provide 95A of peak current while producing voltage rise and fall times of less

than 4ns, and minimum pulse widths of 8ns. The input of the driver is fully immune to latch up over the entire

operating range. Designed with small internal delays, the IXZ4DF18N50 is suitable for higher power operation

where combiners are used. Its features and wide safety margin in operating voltage and power make the

IXZ4DF18N50 unmatched in performance and value.

The IXZ4DF18N50 is packaged in DEI's low inductance RF package incorporating DEI's RF layout techniques

to minimize stray lead inductances for optimum switching performance. The IXZ4DF18N50 is a surface-

mountable device.
