The diode protect the CAN bus lines from the damaging effects of electrostatic discharge (ESD) and other electrical fast transients (EFT). In addition to being AEC-qualified, the ESD diode is compatible with several IEC standards. These include 61000-4-2 (ESD): level 4; 61000-4-4 (EFT): 40 A, 5/50 ns; and with 61000-4-5 (surge): 2,1 A, 8/20 µs. The component offers 150-W peak pulse power per line (typical = 8/20 µs). ESD protection is 15 kV and the rated stand-off voltage is 24 V.

Operating and storage temperatures for the diode are -55 °C to 150 °C. The component also boasts a low clamping voltage, low capacitance, and low leakage current. It is provided in a molded Jedec SOT-23 package with an approximate weight of 8 mg. Other key mechanical characteristics include lead-free pure-tine plating (annealed) and a solder reflow temperature 260 °C to 270 °C. It has a flammability rating of UL 94V-0. It is delivered on 8-mm tape and reel.

In business more than 25 years, Protek is a privately held company. It offers circuit protection devices. This includes overvoltage protection components and overcurrent protection components. Other products include transient voltage suppressors (TVS array), avalanche breakdown diodes, steering diode TVS arrays, PPTC devices, and electronic SMD chip.
