PV Series -
Low & Medium Voltage Plastic-Encapsulated Varistors
*RoHS Directive 2015/863, Mar 31, 2015 and Annex.
Specifications are subject to change without notice.
Users should verify actual device performance in their specific applications.
The products described herein and this document are subject to specific legal disclaimers as set forth on the last page of this document, and at www.bourns.com/docs/legal/disclaimer.pdf.
General Information
The PV series of low and medium voltage plastic-encapsulated varistors is designed
to protect electronic equipment against voltage surges in the low and medium voltage
region. They offer direct SMD equivalents to leaded disc varistors of 5 and 7 mm sizes.
The thermoplastic encapsulation is non-ammable and UL 94 V-0 rated. Contacts are
made of tinned copper sheet.
PV series varistors are designed for surface mounting and are available in two model
sizes.
These transient voltage suppressors cover an operating voltage V
rms
from 11 V to
300 V, featuring maximum surge currents from 100 A to 1200 A.
