概要
Description
SZBZX84B18LT1G is a surface‑mount Zener diode from the BZX84B family. It has a nominal Zener voltage of 18 V and is a low‑power device (about 0.5 W rating). The “B” variant indicates a tolerance of roughly ±5%. The suffix LT1G marks RoHS/compliant, lead‑free packaging. Typical uses include voltage regulation, clamping/protection, and simple reference roles in compact power supplies and signaling circuits. It’s designed for SMD assembly and is suitable where a stable 18 V clamp/reference is required in small electronics.
Equivalent
SZBZX84B18LT1G is the 18V Zener diode in the BZX84B18 family (SOT-23, 0.5W). Equivalents are the standard BZX84B18LT1G parts from major vendors, e.g., Vishay BZX84B18LT1G, and BZX84B18LT1G from Nexperia/ON Semiconductor/Diodes Inc. Any supplier offering the BZX84B18 in SOT-23 (lead-free) is an equivalent.
