Diodes Incorporated has announced an automotive-grade ESD and surge protector offering better protection than Zener-based and varistor devices provide, while offering the same optical solder-inspection capabilities.
In cars, the protection of CAN and LIN two-wire communications buses from voltage transients is critical to their reliability and safety. The D24V0L1B2LPSQ, a bidirectional ESD protection diode rated with a typical capacitance of 6pF at a reverse voltage of 0V, is ideally suited to this application.
Featuring 0.2Î© dynamic resistance, the diode benefits from sharper triggering than Zener diodes or varistors can offer, resulting in superior protection from fast transients such as ESD strikes.
The D24V0L1B2LPSQ, housed in a tiny DFN1006-S package, is the first of its type to feature sidewall plating, sometimes known as âwettable flanksâ. This means that the package sidewall is tin-plated, allowing a solder fillet to be formed. The solder fillet may be inspected optically, eliminating the need for slow and expensive X-ray inspection during PCB assembly.
The D24V0L1B2LPSQ will withstand air discharges and contact electrostatic discharges of Â±20kV.
