Description
■ ISO10605 - C = 150 pF, R = 330
– 30 kV (air discharge)
The ESDCAN24-2BLY is a dual-line Transil
specifically designed for the protection of the
automotive CAN bus lines against electrostatic
discharge (ESD).
– 30 kV (contact discharge)
■ ISO10605 - C = 330 pF, R = 330
– 30 kV (air discharge)
– 30 kV (contact discharge)
■ ISO7637-2:
– Pulse 3a: V = -150 V
s
– Pulse 3b: V = +100 V
s
Application
Automotive controller area network (CAN) bus
lines where electrostatic discharge and other
transients must be suppressed.
