1 ZA Varistor Series RoHS Agency Approvals Agency Approval Agency ile Number Description The ZA Series of transient voltage surge suppressors are radial leaded varistors (MOVs) designed for use in the protection of low and medium-voltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity. These devices are available in five model sizes: mm, 7mm, mm, 4mm and 0mm, and feature a wide V D voltage range of.v to 6V. See ZA Series Device Ratings and Specifications Table for part number and brand information. eatures UL449 except parts V8ZAxx and VZAxx -006 I 6- I 6- I 9- (Annex Q) for 4mm (V0 to V80) and 0mm(V0 to V80) only -006 I 6- I 6- I 9- (Annex Q) for 4mm (V0 to V80) and 0mm(V0 to V80) only / Lead free, Halogen- ree and RoHS compliant ide operating voltage range V M(A)RMS 4V to 4V D voltage ratings.v to 6V No derating up to 8º ambient Additional Information model sizes available:, 7,, 4, and 0mm Radial lead package for hard-wired or printed circuit board designs Available in tape and reel or bulk pack Standard lead form options Datasheet Resources Samples Absolute Maximum Ratings or ratings of individual members of a series, see Device Ratings and Specifications chart ontinuous ZA Series Units Steady State Applied Voltage: A Voltage Range (V M(A)RMS ) 4 to 4 V D Voltage Range (V M(D) ). to 6 V Transients: eak ulse urrent (I TM ) or 8/0µs urrent ave (See igure ) to 6 A Single ulse nergy Range (Note ) or /00µs urrent ave ( TM ) 0. to J Operating Ambient Temperature Range (T A ) - to +8 º Storage Temperature Range (T STG ) - to + º Temperature oefficient (a V ) of lamping Voltage (V ) at Specified Test urrent <0.0 %/º Hi-ot ncapsulation (OATING Isolation Voltage apability) (Dielectric must withstand indicated D voltage for one minute per MIL STD 0, Method ) V OATING Insulation Resistance 00 MΩ AUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device.
