Product details

TVS diode for high-energy transient clamping

It clamps transients at 18.2V maximum while standing off 9.9V reverse voltage, making it a fit for 12V nominal rail protection in industrial and automotive environments. With a minimum breakdown voltage of 12.35V, the device triggers before the 18.2V clamp, ensuring the protected load sees minimal overvoltage during a surge event.

Peak pulse current and clamping performance

The 82.4A peak pulse current rating (10/1000µs) defines the surge capacity for direct lightning strikes or inductive kickback from motors and solenoids. At 1500W peak power, this TVS can absorb repetitive pulses as long as the junction temperature stays within the -55°C to 175°C limit. The 18.2V clamping voltage at Ipp ensures that downstream semiconductors rated for 20V or higher survive the clamped transient without secondary protection.

Active production – no obsolescence risk

No end-of-life notice or successor has been issued, so this part remains a safe choice for new designs and ongoing production.
