5KP22V TVS Diode Uni-directional 35.5V 141A
The 5KP22V is a high-energy transient voltage suppressor (TVS) from the 5KP series, designed to absorb large surge pulses and clamp transient overvoltages on power lines and high-power DC buses. It is part of a 5,000 W class of suppressors in the R-6/P600 molded package, offered in uni- and bi-directional versions. The device is engineered to protect systems from lightning-induced surges and switching transients by conducting the transient current to ground and keeping the clamped voltage well below destructive levels.
Mechanically the part is a robust, glass-passivated chip junction in a JEDEC R-6/P600 molded plastic package, suitable for heavy duty transient events. Its construction yields low dynamic impedance so the clamping voltage rises minimally as surge current increases; this lets the device limit the peak voltage seen by protected circuitry. The datasheet also specifies high-temperature solder endurance and reflow parameters for board assembly.
Electrically the 5KP22V is specified with a 22 V stand-off (VR) and a tightly controlled breakdown/clamp behavior at specified test currents. It supports connection in series/parallel to scale capacity, and is rated for very high single-pulse energy (5000 W peak power on a 10×1000 μs waveform) while providing fast response (<1.0 μs). These traits make it suitable for industrial and utility environments where occasional extremely large surges must be dissipated without damaging downstream components.
Features:
- Low zener/ dynamic impedance for effective clamping.
- Excellent clamping capability (5000 W peak pulse power, 10×1000 μs).
- JEDEC R-6 / P-600 molded plastic package with glass-passivated junction.
- Uni- and bi-directional versions available.
- Fast response time (typically <1.0 μs).
- Rated for high forward surge and robust soldering (high-temperature reflow capable).
