This document introduces a low profile package device for surface mounted applications, which features built-in strain relief, glass passivated junction, low inductance, and excellent clamping capability. It is lightweight, compact in size, suitable for high temperature soldering, and has good flame retardancy.
The SMCJ Series from WEITRON are 1500 W surface‑mount transient voltage suppressors designed for high‑speed protection in electronic circuits. Key features include a low‑profile JEDEC DO‑214AB package, built‑in strain relief, glass‑passivated junction, low inductance, and excellent clamping capability.
The datasheet lists maximum ratings such as a 5 V to 440 V voltage range, peak pulse power of 1500 W, and a repetition rate of 0.05 %. Mechanical data, dimensions, thermal impedance curves, and typical junction capacitance are also provided to aid designers in layout and reliability calculations.
