ProTek Devices has uncloaked an asymmetrical line protection transient voltage suppressor array (TVS array) geared for local interconnect network (LIN) BUS protection in industrial applications such as field devices, protocol converters and gateways, and more. According to the company, the circuit protection device is rated at 200W peak pulse power per line. This is for an 8/20 secondary lightning surge, noted ProTek.

The part number is the PESD1LIN and is available in a bidirectional configuration. The PESD1LIN is intended as a replacement for multilayer varistors (MLV 0805) in LIN BUS applications. It protects one power or I/O port and asymmetrical line protection is pin 1 to 2, 15V and pin 2 to 1, 24V. In addition, the TVS array provides a low clamping voltage. The minimum breakdown voltage at 15mA is 17.2V for pin 1 to 2 and 25.5V for pin 2 to 1. It also provides IEC compatibility with standards 61000-4-2 (electrostatic discharge [ESD]): Air - 15kV, contact - 8kV, with 61000-4-4 (electrical fast transients [EFT]): 40A - 5/50ns, and with 61000-4-5 (surge): 24A, 8/20ms - level 2 (line-gnd) and level 3 (line-line).

The flammability rating is UL 94V-0. The part is also RoHS and REACH compliant. Operating and storage temperatures are -55°C to 150°C. The PESD1LIN TVS array is provided in a moulded JEDEC SOD-323 package at about 5mg. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin, 100) 260°C to 270°C.

The PESD1LIN circuit protection component is available in mass quantities and pricing varies by amounts. It is provided in 3,000 minimum quantities via eight 8mm tape and reel, per EIA standard 481. A datasheet for the PESD1LIN can be download from the ProTek Devices website.
