A new series of AEC-Q101 qualified transient voltage suppressor arrays (TVS arrays), has been introduced by ProTek Devices, for circuit protection in aerospace, automotive, consumer electronics, intelligent control systems and telecommunications applications. The new PAM37SDxxAL/CAL series is available in multiple voltages.

The TVS components are compatible with IEC standards 61000-4-2 (ESD): air ±15kV, contact ±8kV, 61000-4-4 (EFT): 40A, 5/50ns, and with 61000-4-5 (surge): 8/20 micro seconds waveform. They also provide 400W peak pulse power per line (typical = 10/1000 micro seconds), low inductance and first-rate clamping capability.

In addition, the PAM37SDxxAL/CAL series of TVS arrays offer unidirectional and bidirectional configuration options, low leakage current of less than 1 microampere (typical), a fast response time and are also RoHS and REACH compliant.

The PAM37SDxxAL/CAL series is now available in the space-saving molded SOD-123FL package with an approximate weight of just 0.0136 grams. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature (pure-tin - Sn, 100) of 260-270 degrees Celsius.

The components are provided on 12mm tape and reel per EIA standard 481 in quantities starting at 3,000. The new TVS array series also has a flammability rating of UL 94V-0.

Pricing information and purchasing details can be had by contacting any authorised worldwide distributor, representative, or directly with ProTek Devices.
