Frequently Asked Questions
What breakdown voltage range does the ESDCAN04-2BLY provide?
The ESDCAN04-2BLY has a breakdown voltage ranging from 27.5V minimum to 30.7V maximum, with a 29.1V nominal value, and clamps transients to a maximum of 43V to protect CAN bus transceivers from voltage spikes.
How is the ESDCAN04-2BLY configured to protect a CAN bus pair?
This TVS diode uses a common-anode, 2-element, 2-channel silicon configuration housed in a 3-pin SOT23-3L package, allowing a single device to protect both CAN_H and CAN_L lines simultaneously on a 12V bus.
Why should buyers plan early when ordering the ESDCAN04-2BLY?
STMicroelectronics currently quotes a standard factory lead time of roughly 53 weeks for the ESDCAN04-2BLY, so procurement teams sourcing this 2-channel automotive TVS diode should place orders well ahead of production ramp to avoid shortages.
