What does ZD stand for?

Some of the critical specifications of the LuxGuard CM1771 include: back-to-back zener diode configuration for bi-directional ESD protection; safely dissipates ESD strikes of at least 6 kV, Human Body Model, 100 volt breakdown voltage (typical), top pad composition: Gold; and compact flip chip package.

It uses a zener diode that divides the gate of a rectifier, which are silicon controlled latches of any high voltage.

Key features include the following: -- 4, 6, or 8 channels of high-speed ESD protection in a single integrated device -- Integral zener diode clamp to suppress supply rail transients -- +/-15KV contact,+/-15KV air ESD protection per channel (IEC 61000-4-2 standard) -- Low loading capacitance-6pF typical -- Low supply current (less than 10 uA) for low power applications -- Clamping voltage less than 15V (Vp + 10V) with no higher trigger voltages -- Sub-nanosecond response times An important feature is these devices do not exhibit device degradation under repetitive ESD strikes that fall within their specification and can survive more than 1000 ESD events without degradation.

The Major Product Segments Analyzed are Small Signal Diode, Transient Protection Diode, Zener Diode, and Radio Frequency & Microwave Diode.

Additionally, they have built-in Zener diodes that protect the LCD controller and the I/O ports against damage from ESD of up to 15kV rated to meet IEC61000-4-2 standard level 4 ESD requirements.

SSI's Zener diodes provide engineers yet another choice to optimize their power supply designs, as they offer both quality and value," said Paul Buckley, Senior VP, Sales and Supplier Management, Newark.

com) is a leading manufacturer of power semiconductors, featuring a comprehensive range of rectifiers, bridge rectifiers, switching diodes, Zener diodes, and Transient Voltage Suppressors (TVS).

A unique feature is the way it instructs how to handle Zener diodes in power supplies and opamps in switching circuits, describing stabilization of voltage and the laws governing change behaviour.
