The company’s hybrid semiconductor solutions are patent pending and will target circuit protection in common household and industrial applications as ideal replacements for surface mount MOVs.
TEMPE, Ariz. – September 13, 2022 – ProTek Devices has introduced hybrid semiconductor technology that is the company’s first ever for circuit protection in common industrial and household applications such as power adapters, household appliances , industrial automation controls, smart meters and other critical applications. New patent-pending technology makes the new devices ideal replacements for high-end surface-mount metal-oxide varistors (MOVs).
ProTek Devices’ new hybrid transient voltage suppression components (TVS component) offer several unique benefits. They offer a more robust product in a small form factor that does not use the wear mechanism present in gas discharge tubes (GDTs) and MOVs. Therefore, the operational life and reliability are significantly extended. The new components, the PHYTVSxxxV3 and PHYTVSxxxV4 series, provide a reliable surge solution when lower blocking voltage is required. Each series is made up of three component offerings.
Both series are compatible with IEC 61000-4-5 (overvoltage). However, the PHYTVSxxxV3 is class LL 2, for 500V 1.2/50 microseconds – Req = 2 ohm, i.e. 250A 8/20 microseconds, and the PHYTVSxxxV4 is class 3, 1kV 1.2/50 microseconds – Req = 2 ohm, or 500A 8/20 microseconds. Both also feature bi-directional operation for 50/60/400Hz AC lines. Additionally, both series are available for SMT reflow soldering, have an operating temperature of -55 to +125 degrees Celsius, and are RoHS and REACH compliant.
The PHYTVSxxxV3 and V4 series also meet and exceed IEC 61000-4-2 (ESD): Level 4 Air plus or minus 15 kV, contact plus or minus 8 kV and IEC 61000-4-4 (EFT): 40 A.
Mechanical details and availability information
Both series come in a DFN-2-KW package. The PHYTVSxxxV3 has an approximate weight of only 2.5 grams and the PHYTVSxxxV3 is only 0.75 grams. The PHYTVSxxxV3 has a form factor compatible with SMT 3225. Other mechanical features include lead-free tin plating for the PHYTVSxxxV3 and lead-free silver plating for the PHYTVSxxxV4. They both have a solder reflow temperature of (260-270 degrees Celsius, 10 seconds. Finally, both series have a flammability rating of UL 94V-0. A datasheet for the PHYTVSxxxV3 is available here and for the PHYTVSxxxV4 is available here.
Both series of hybrid TVS components are available on 12mm tape and reel, conforming to EIA 481, in minimum quantities of 1,000.
