Multilayer Varistors offer operating temperature up to 150°C.
Press Release Summary:
RoHS compliant SMD multilayer varsitors feature low capacitance for response time of less than 2 nsec. With operating voltages ranging from 3-170 Vdc, and from 2-130 Vac, ZVY series is suited for industrial and high-temperature controls for ESD, switching, and inductive transient protection on circuit boards and ICs. AVY series is designed for standard automotive voltages of 12, 24, and 42 V, and is characterized for 5 min at Vjump and for 10X load dump energy.

Stackpole Electronics, Inc. Introduces the ZVY / AVY Series High-Temperature Automotive and Low-Voltage SMD Varistors
The industry's highest temperature rating capability for any multilayer varistor...
RALEIGH, N.C. (September 5, 2006)- Stackpole Electronics, Inc., though its strategic alliance with KEKO Varicon, introduces the ZVY and AVY series SMD multilayer varistors designed for maximum operating temperatures up to 150°C. Most multilayer varistors are only rated for operation up to 85°C, and recently there have been increasing numbers of varistors designed for operation up to 125°C. However, automotive and industrial control market trends have driven the need for low-voltage transient protection for temperatures above 125°C. The RoHS-compliant ZVY and AVY series fulfill this emerging market trend.
"We have recently seen an increase in demand for transient voltage protection devices at temperatures above 125°C, especially in Europe," says Kory Schroeder, Product Engineering Manager at Stackpole. "And in the United States, the automotive industry required varistor protection at these elevated temperatures for some time, but technology was not able to meet those needs until now."
The ZVY series is a SMD varistor that is an extension of the ZV series low-voltage SMD multilayer varistors. It is available in sizes 0603, 0805, 1206, 1210, 1812 and 2220. Operating voltages range from 3VDC to 170VDC, and from 2VAC to 130VAC. The ZVY series features low capacitance for a fast response time of less than two nanoseconds. This product has a wide range of current and energy handling capabilities and can be customized for special current, energy or capacitance requirements. The ZVY varistors are well suited for industrial and high-temperature controls for ESD, switching and inductive transient protection on circuit boards and ICs.
The AVY series is a SMD varistor that is an extension of the AV series of automotive multilayer SMD varistors. This product is similar to the ZV series but designed specifically for the standard automotive voltages of 12V, 24V and 42V. It is available in sizes 0805, 1206, 1210, 1812, 2220 and 3225, and is characterized for five minutes at Vjump and for 10X load dump energy (WLD), which are critical for the automotive industry. The AVY series has low capacitance for fast response time of less than two nanoseconds. It has a broad range of current and energy handling capabilities, and is customizable to fit any special requirements for current, energy or capacitance. The AVY varistor is ideal for all automotive transient protection needs, and offers more layout flexibility for the design engineer since it uses less space than silicon TVS diodes.
Pricing depends on size and voltage, and typically ranges from $0.15 to $0.50 for 10,000 pieces and greater. Lead times are currently eight to 10 weeks.

KEKO VARICON continues the tradition of ceramic electronic components started by Iskra Group 45 years ago. KEKO VARICON headquartered in Zuzemberk, Slovenia, has produced over-voltage protection devices for 10 years. Its name was derived from "VARistor" and "CONdensator," the old term for a capacitor. Today, KEKO VARICON is a leading supplier of over-voltage protection devices to many of the top electronics companies throughout the world. KEKO VARICON and SEI have formed a strategic alliance to jointly promote the sale of KEKO's products throughout North America.
