1 RoHS Description The 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 mm, and feature a wide V DC voltage range of.v to 6V.

The power so developed must be within the specifications shown on the Device Ratings the operating values need to be derated at high temperatures as shown in the diagram above. Because varistors can only dissipate a relatively small amount of average power they are, therefore, not suitable for repetitive applications that involve substantial amounts of average power dissipation. 0 T = Rise Time =. x T T = Decay Time xample μ 8μs = T = Rise Time μs = T = Decay Time Maximum Clamping Voltage for mm arts V8ZA0() - V68ZA0() MAX CLAMING VOLTAG MODL SIZ mm 8 TO 68V N(DC) RATING 90 V68ZA0() V6ZA0() 60 V47ZA0() V39ZA0() 40 V33ZA0() V7ZA0() 30 VZA0() V8ZA0() VZA0() -3 V8ZA0() V360ZA0() - V7ZA0() Figure 3 Figure 4 V8ZA0() - V33ZA0() V330ZA0() V70ZA0() V40ZA0() VZA0() VZA0() V80ZA0() VZA0() VZA0() MAX CLAMING VOLTAG MODL SIZ mm 8 TO 330V N(DC) RATING VZA0() V8ZA0() V7ZA0() V7ZA0() V680ZA0() V6ZA0() V470ZA0() V430ZA0() V390ZA0() V360ZA0() MAX CLAMING VOLTAG MODL SIZ mm 360 TO 7V N(DC) RATING Figure Littelfuse, Inc.
