ProTek Devices’ TVS array provides circuit protection

The new PSM36A can deliver circuit protection in IO-link sensor transceiver interfaces, 2-wire sensors, and 3-wire DC proximity switches, amongst other industrial or sensor applications. Circuit protection includes defence from electrostatic discharge (ESD), tertiary lightning, and switching transients.

The TVS array is compatible with several IEC standards. These include 61000-4-2 (ESD): air plus or minus 30kV, contact plus or minus 30kV, with 61000-4-4 (EFT): 40A, 5/50ns, and with IEC 61000-4-5 (surge): Class 2, 1kV, Req = 42 Ohms. It features 2400 watts peak pulse power per line (typical = 8/20 microseconds) and a low clamping voltage of less than 60V @ 40Apk 8/20 microseconds surge.

It also provides for unidirectional configuration and has a low leakage of 200nA at 36V. As a lead-free component, it is essentially a green device. It also is RoHS and REACH compliant.

Mechanical details and availability information

ProTek Devices’ PSM36A is now available, provided in a moulded JEDEC SOT-23 package with an approximate weight of just eight milligrams. It has lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin – Sn, 100) of 260-270 degrees Celsius. It also has a flammability rating of UL 94V-0. The operating and storage temperature is -55 to 150 degrees Celsius. It is available via 8mm tape and reel, per EIA standard 481, in quantities from 3,000. Customers, distributors and other partners can view the product data sheet for more information.
