Vishay Introduces Telefunken TLZ Series Zener Diodes

August 29, 2001 by Jeff Shepard

Vishay Intertechnology Inc. (Malvern, PA) introduced the Telefunken TLZ Series of zener diodes, which are offered in compact MiniMELF (SOD-80) housings. They give designers 130 options for constant voltage-control applications in a surface-mount glass package, enabling high-density board layouts and simplifying high-speed assembly.

The devices boast of power handling capabilities up to 500mW at zener voltages from 2.4V to 56V and reverse currents from 5mA to 20mA. A sharp reverse characteristic helps ensure a stable reverse voltage, even at low current levels. This also promotes efficient use of power in dc/dc converters, computer motherboards, power supplies, consumer products and communications systems.

The Zener diodes are offered in 30 overlapping voltage groups. Within each group, from three to six devices are offered with more narrowly specified reverse voltages. The glass MiniMELF package measures only 3.5mm x 1.5mm. The devices are specified for 175 degrees C maximum junction temperature.
