high-current zener diodes (Z_CXa and Z_CXb) 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-kΩ
resistor.
The TPIC1321L is offered in a 24-pin wide-body surface-mount (DW) package and is characterized for
operation over the case temperature of − 40°C to 125°C.
