Metal-Oxide Varistors (MOVs) Axial Lead / Application Specific Varistors > MA Series MA Varistor Series RoHS Description The MA Series of transient surge suppressors are axial lead Metal Oxide Varistors (MOVs) for use in a wide variety of board level industrial and commercial electronic equipment. They are intended to protect components and signal/data lines from low energy transients where the small axial lead package is required. The MA Series is offered with standard ('S' suffix) or tightened ('B' suffix) clamping voltage. See MA Series Device Ratings and Specifications Table for part number and brand information.

CURRENT, AND POWER Should transients occur inENERGY rapid succession, the DERATING average power CURVE dissipation required is simply the energy (watt-seconds) per pulse times the number of pulses per second. The power so developed must be within the specifications shown on the Device Ratings and Specifications table for the specific device. Furthermore, the operating values need to be derated at high temperatures as shown 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.

SURGE CURRENT RATING CURVES FOR V120MA SERIES - V430MA SERIES NOTE: If pulse ratings are exceeded, a shift of VN(DC) (at specified current) of more than +/-10% could result. This type of shift, which normally results in a decrease of VN(DC), may result in the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection. MAXIMUM PEAK VOLT MAXIMUM PEAK VOLT Axial Lead / Application Specific Varistors > MA Series 80 100 60 V47MA2A/S V39MA2A/S V33MA1A/S V27MA1A/S V22MA1A/S V18MA1A/S 40 30 20 10 -2 Maximum Clamping Voltage 200 150 100 80 60 40 200 150 100 80 60 40 30 30 20 10 -2 10 -1 20 10 -2 2,000 Figure 5 V47MA2A/S V47MA2A/S V39MA2A/S V39MA2A/S V33MA1A/S V33MA1A/S V27MA1A/S V27MA1A/S V22MA1A/S V22MA1A/S V18MA1A/S V18MA1A/S 10 -1 10 0 10 1 10 2 10 0 PEAK AMPERES 10 1 10 2 (A) PEAK AMPERES (A) 1,500 1,000 800 600 400 200 30 100 20 10 -2 10 -3 -1 10 100 10 -2 Figure 6 V56MA2B V47MA2B V39MA2B V33MA1B V180MA1A V27MA1B V150MA1A V180MA1A V22MA1B V120MA1A/S V150MA1A V18MA1B V120MA1A/S 10 -1 -1 10 0 10 1 10 -2 10 10 0 1 10 1 10 2 0 10 10 10 2 PEAK AMPERES (A) PEAK AMPERES (A) PEAK AMPERES (A) 600 100 90 400 80 70 60 50 200 40 30 100 2010 -2 10 -3 10 2 Figure 7 100 90 80 70 60 50 40 V56MA2B V47MA2B V56MA2B V39MA2B V47MA2B V39MA2B V33MA1B V27MA1B V33MA1B 30 V180MA1A V22MA1B V27MA1B V150MA1A V18MA1B V22MA1B V120MA1A/S V18MA1B 20 -3 0 10 -2 10 0 10 -1 1010 1010 10 1 10 2 10 2 -1 1 -2 -1 0 10 10PEAK AMPERES 10 PEAK(A) 10 1 10 2 10 3 AMPERES (A) PEAK AMPERES (A) 3,000 MAXIMUM PEAK VOLTS (V) 800 V100MA4B V82MA3B V68MA3B 2,000 1,000 900 800 700 600 500 400 300 1,000 900 800 700 600 500 400 300 200 100 10 -3 10 -2 Figure 8 10 -2 10 -1 10 0 10 1 1 10 -1 10 0 PEAK 10AMPERES 10 2(A) PEAK AMPERES (A) 10 3 10 2 10 3 FIGURE 5.
