Product Description


High Temperature Chip Multilayer Surface Mount Zinc Metal Oxide Varistor 07D561K ZOV Disk SMD


General Description Of The Zinc Metal Oxide Varistor


Multilayer varistors are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear voltage-current characteristics (bi-directional) similar to back- to-back zener diodes. They have the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. The increasing use of electronics technologies in all areas require reliable protection against transient voltages that could damage the electronics circuitry as well as EMI/RFI attenuation to prevent signal distortion and to meet regulatory requirements. AMPFORT components help achieve both functions with single component.

500-2000A Multilayer Chip Varistor Surface Mount Zinc Metal Oxide for Alarms 2

Highly Recommended:
1. In the drawing board, it is recommended that the A solder joint be used as the L line, the B solder joint

as the N line, and the copper skin connected to the B solder joint is routed around the pressure-sensitive

chip circle (the entire diameter D should be regarded as belonging to the A solder joint.

2. For the sake of safety arcing, the circular edge of the chip should be at least 2.5mm away from any other

conductive device, as shown in the figure above (in order to prevent mutual displacement with other devices

during patching, if the space allows, please reserve the larger the interval is. Okay.)
3. The use of varistors in DC circuits has unfavorable factors. It is not recommended to use varistors in

rectified DC circuits. Please consider carefully or contact our company at 18128566098 (sales1@ampfort.net),

thank you!

For different voltage application environments, we recommend the following pressure sensitive

combinations to provide overvoltage, surge and lightning stroke protection for ACLED. 

Working Voltage
Forestage Varistor Parameter Back-end Varistor Parameter Remarks
110VAC±20% 270VDC±10% / In view of the insufficient voltage withstand capability of the IC, the two-stage varistor can be upgraded to 4KV lightning protection. The user can choose the varistor size according to the requirements of the anti-surge level.
220-230VAC±20% 510VDC±10% 470VDC±10%
240VAC±20% 560VDC±10% 510VDC±10% The combination is recommended for users in Indian and Brazil.

Since pressure sensitive resistor is easy to degrade under the environment with strong voltage fluctuation,

it is required to select the combination with high pressure sensitive voltage value as much as possible

under the premise that withstand voltage of IC (MOS tube) +lamp bead on lamp board is pretty high

and that voltage has a large fluctuation area; besides, it is necessary to select pressure sensitive
resistor with large circulation and volume as far as possible, without exceeding cost limit.

The picture above shows the approximate trend of the reflow oven temperature curve on the market. Our

SMD pressure sensor uses the silver electrode of the ceramic body as one of the welding electrodes.

Please pay attention to setting the oven temperature and time (if the highest temperature is 260°C,

please Note that the time is 3-8S, if it exceeds 30S, the protection effect of the varistor will be affected).
