Vishay's PLZ Series Zener diodes with 500 mW of power dissipation in the new ultra-compact MicroSMF eSMP® series package combine extremely tight voltage tolerances with low-leakage current and excellent stability. The PLZ series is designed to withstand ESD pulses of 8000 V (human body model), save PCB space, and increase pick-and-place speed for assembly lines.

These devices offer 500 mW power dissipation with voltage tolerances of ±2.5% in a symmetrical class SOD-323 flat lead package. With their compact footprints and low profiles of <0.6 mm, PLZ series devices save significant PCB space when compared to diodes in similar plastic or glass SMD packages.

PLZ series diodes feature a planar structure to guarantee high performance, ruggedness, and reliability characteristics. The devices provide a moisture sensitivity level (MSL) of 1 per J-STD-020, LF maximum peak of +260°C; meet the JESD 201 Class 2 whisker test; and are RoHS-compliant, halogen-free, and Vishay GREEN. Ideal for automated placement, the diodes support wave and reflow soldering and allow for automated optical inspection (AOI) systems.

The devices are optimized for voltage stabilization and reference voltage generation in power supplies and LED lighting.
