The SZMMBZ18VALT1G is a dual monolithic Zener TVS diode designed for transient overvoltage protection. It features a common anode configuration with two unidirectional channels and one bidirectional channel, allowing protection of two separate lines in a single SOT-23-3 package. Key electrical specifications include a maximum clamping voltage of 25 V, peak pulse current of 1.6 A, and peak pulse power of 40 W at 1.0 ms. The device has a nominal breakdown voltage of 18 V.
This TVS diode is rated for ESD protection up to 30 kV contact discharge per IEC 61000-4-2 Level 4, and meets Class 3B (16 kV) HBM and Class C (400 V) MM standards. It is designed for automotive applications, indicated by the SZ prefix, and is AEC-Q101 qualified and PPAP capable. The part is Pb-free and RoHS compliant, with a flammability rating of UL 94 V-0.
The device is surface-mount in a SOT-23-3 (TO-236) package, suitable for high-density board assembly. It can withstand a maximum soldering temperature of 260°C for 10 seconds. Standard packaging is on 7-inch reels of 3,000 units (T1 suffix) or 13-inch reels of 10,000 units (T3 suffix).
