It has been announced that ProTek Devices has introduced a new circuit protection diode suited for automotive applications, such as Controller Area Network (CAN) bus lines. The new PAM3CAN diode is qualified by the Automotive Electronics Council (AEC).
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.
