Bourns ZV and ZVHT SMD Low-Voltage Varistors are designed to replace larger surface-mount TVS Zener Diodes in many applications. Two types are available: ZV (Low Voltage) and ZVHT (Low Voltage, High Temperature). The varistors protect sensitive electronic devices against high-voltage surges in the low-voltage region. The series offers excellent transient energy absorption due to improved energy volume distribution and power dissipation. The components cover a wide DC operating voltage range from 3V to 170V. The varistors also exhibit independent suppression characteristics, enabling stable protection over a wide temperature range of -55°C to +125°C (ZV) and -55°C to +150°C (ZVHT). Bourns ZV and ZVHT applications include the protection of integrated circuits and other components at the circuit board level.
