The ZV50S2220452NIR1 from Bourns is a Low Voltage Multilayer Varistor that has been designed to protect sensitive electronic devices against high-voltage surges in the low-voltage region. It has an AC voltage rating of 50 V (RMS), a DC voltage rating of 63 V, and a clamping voltage of 115 V. This varistor has a clamping current of 10 A, a capacitance of 8800 pF and a power rating of up to 0.020 W. This varistor has a short response time and low clamping voltage. It has a peak pulse surge current of 4500 A and a response time of less than 2 ns. It offers low sensitivity to mildly activated fluxes and has a continuous operating temperature of +125 °C. This RoHS-compliant varistor is available in a surface-mount package that measures 5.7 x 5.0 x 3.3 mm and is ideal for suppression of inductive switching or other transient events, a replacement for TVS Zener diodes, electromagnetic compliance of end products and on-board transient voltage protection applications.
