The TPIC5401 is a monolithic gate-protected power DMOS array that consists of four N-channel enhancement-mode DMOS transistors, two of which are configured with a common source. Each transistor features integrated high-current zener diodes (ZCXa and ZCXb) to prevent gate damage in the event that an overstress condition occurs. These zener diodes also provide up to 4000 V of ESD protection when tested using the human-body model of a 100-pF capacitor in series with a 1.5-k resistor. The TPIC5401 is offered in a 16-pin thermally enhanced dual-in-line (NE) package and a 20-pin wide-body surface-mount (DW) package and is characterized for operation over the case temperature range of 40C to 125C.
