Vishay Intertechnology 500 mW Zener diodes save on PCB space

Vishay Intertechnology has introduced the first new series of Zener diodes with 500 mW of power dissipation in the new ultra-compact MicroSMF eSMP series package. Combining 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. 

The Vishay Semiconductors 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 with diodes in similar plastic or glass SMD packages. The devices are optimized for voltage stabilization and reference voltage generation in power supplies and LED lighting.

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.

Samples of the new PLZ Series Zener diodes are available now. Production quantities will be available in Q4 2014.
