Diodes Incorporated has announced an automotive-quality graded ESD and surge protector offering improved protection, greater reliability and easier inspection during manufacturing compared to Zener-based and varistor devices. Protecting CAN and LIN two-wire communications busses in automobiles from voltage transients is critical to their reliability and safety. The D24V0L1B2LPSQ is a low-capacitance, 15pF device with 0.2Ω dynamic resistance that provides sharper triggering than Zener diodes or varistors to provide a superior protection solution.
The DFN1006-S-packaged automotive-grade component (AECQ101-qualified, supported by PPAP traceability) is also 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 can then be optically inspected, eliminating the need for slow and expensive X-ray inspection during PCB assembly. Furthermore, the DFN1006-S package footprint is compatible with that of the SOD923 package.
With a rated standoff voltage of 24V, the D24V0L1B2LPSQ will withstand air discharge and contact electrostatic discharges of up to 30kV, far exceeding the requirements of the IEC61000-4-2 standard. The D24V0L1B2LPSQ ESD and surge protector is priced at $0.1USD each in quantities of 3k.
