The PAM3CAN is designed to protect two automotive CAN bus lines from the damaging effects of electrostatic discharge (ESD) and other electrical fast transients (EFT). In addition to being AEC-qualified, the new ESD diode is compatible with several IEC standards. These include 61000-4-2 (ESD): level four; 61000-4-4 (EFT): 40A, 5/50ns; and with 61000-4-5 (surge): 2.1A, 8/20 micro seconds. The diode offers 150W of peak pulse power per line (typical = 8/20 micro seconds). ESD protection is 15kV. The rated stand-off voltage is 24V.
Operating and storage temperatures for the diode are -55 to +150°C. The PAM3CAN also boasts a low clamping voltage, low capacitance, and low leakage current. It is RoHS and REACH compliant.
The PAM3CAN ESD circuit protection diode is now available and is provided in a molded JEDEC SOT-23 package with an approximate weight of only eight milligrammes. Other key mechanical characteristics include lead free pure tine plating (annealed) and a solder reflow temperature of (pure-tin – Sn, 100) 260 to 270°C. It has a flammability rating of UL 94V-0. It is delivered on eight millimetre tape and reel, per EIA standard 481, in minimum quantities of 3,000.
