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 0.2Ω 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 ‘wettable flanks’. 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 ±20kV.
