ProTek Devices’ DFN-2KW package for hybrid solid-state circuit protection devices

They offer a more robust product in a small form factor that does not use a wear mechanism found in gas discharge tubes and MOVs.

ProTek Devices has introduced a hybrid semiconductor technology that is the company’s first for circuit protection in common industrial and household applications such as power supplies, home appliances, industrial automation controls, smart meters and other critical applications. The new patent-pending technology makes the new devices the ideal replacement for high-end surface mount metal oxide varistors (MOV).

ProTek Devices’ latest hybrid surge protection (TVS) devices have several unique advantages. They offer a more robust product in a small form factor that does not use a wear mechanism found in gas discharge tubes (GDTs) and MOVs. Therefore, the service life and reliability is significantly increased. The new PHYTVSxxxV3 and PHYTVSxxxV4 series devices offer a reliable overvoltage solution when a lower clamping voltage is required. Each series consists of three component offerings.

Both series are compatible with the IEC standard 61000-4-5 (Surge). However, the PHYTVSxxxV3 is LL Class 2, for 500V 1.2/50 microseconds – Req = 2 ohms or 250A 8/20 microseconds, and the PHYTVSxxxV4 is Class 3, 1 kV 1.2/50 microseconds – Req = 2 ohms or 500 A 8/ 20 microseconds. Both also feature bi-directional operation for 50/60/400 Hz AC power lines. In addition, 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 meets and exceeds 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 weighs only 0.75 grams. The PHYTVSxxxV3 has a form factor compatible with SMT 3225. Other mechanical properties include a lead-free matte tin plating for the PHYTVSxxxV3 and a lead-free silver plating for the PHYTVSxxxV4. Both have a solder reflow temperature of (260-270 degrees Celsius, 10 seconds). Finally, both series have a UL 94V-0 flammability rating. A data sheet 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 in minimum quantities of 1,000 per EIA Standard 481.
