MAX30034CUA+

The MAX30034CUA+ is a defibrillation/surge/ESD protector in 8 pin µMAX package. This patent pending protection device is intended to (with the help of external, energy rated resistors) absorb repetitive defibrillation and other high energy pulses to protect sensitive electronic circuitry in ECG and other medical/industrial equipment. The device can withstand over 100,000 defib pulses without failure. It is intended to replace the gas discharge tubes and transient absorbers in applications where its significant reduction in size is beneficial and its lower, well defined on-voltage can offer higher degrees of protection to sensitive electronics. The MAX30034 uses a combination of a rugged integrated circuit process and high speed circuitry to ensure very fast turn-on times with trigger voltages low enough to not require secondary clamping circuitry. A low hold current of approximately 175mA ensures protection is maintained for the entire length of the high-energy transient event.
