ProTek Devices has just announced a “new family of high-powered surface mount transient voltage suppressors (TVS) for high-voltage spike circuit protection applications that include relay drives, motors (start/stop), module lightning protection and for secondary lightning protection. The SM10KW33A and SM10KW36A TVS components provide 8,500 watts of peak pulse power dissipation for a 10/1000 micro second waveform.”
Benefits of these TVS include: lower cost, lower profile, light-weight of 2.5 grams, high voltage spoke circuit protection, ability to operate in a temperature ranges from are -55 to 150 degrees Celsius, lead-free silver plating, and a UL 94V-0 flammability rating.
“The SM10KW33A has a rated stand-off voltage of 33 volts while the SM10KW36A’s is 36 volts. Also, the SM10KW33A has a minimum breakdown voltage of 36.8 volts while the SM10KW36A’s is 40.0 volts. Maximum clamping voltage for the SM10KW33A is 56.6 volts at 150.0 amps while the SM10KW36A is 60.7 volts at 140.0 amps. These TVS components are IEC compatible with standards 61000-4-5 (surge): 48A, 8/20 micro seconds – L3 (line-ground), L4 (line-line), and L1 (power). They feature a unidirectional configuration and easy mounting to a printed circuit board. They are also RoHS and REACH compliant.”
