Transient Voltage Suppressors suit magnetic environments.
September 21, 2011 -
Designed specifically for MRI machines, Models USBQNM504xx and USBQNM504xxC protect uni-directional and bi-directional lines, respectively. Non-magnetic, halogen-free TVS arrays guard against circuit damage caused by electrostatic discharge, electrical fast transients, and effects of secondary lightning. Offered in quad flat, no-lead, 143-pin metal lead frame, RoHS-compliant suppressors feature peak power rating of 500 W for 8/20 Ásec pulse.

Microsemi Delivers New Voltage Suppression Solutions for Magnetic Environments
Non-ferrous TVS Arrays Designed Specifically for MRI Machines
ALISO VIEJO, Calif., -- Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced two new non-magnetic, 500-watt transient voltage suppressor (TVS) arrays. The new devices were designed specifically for MRI machines to guard against circuit damage caused by electrostatic discharge, electrical fast transients, and the effects of secondary lightning. The USBQNM504xx and USBQNM504xxC TVS arrays are available today, and have already been qualified for use by a major medical equipment manufacturer.
"Our high-performance TVS arrays use non-ferrous metal in their packaging, which makes them ideally suited for operation in MRI machines and other medical devices that operate in powerful magnetic environments," said Simon Wainwright, vice president of Marketing and Business Development for Microsemi's HiRel Group. "This capability adds another layer of protection against damaging voltage spikes that can corrupt data in sensitive medical equipment and render inaccurate results that may negatively impact patient health."
The USBQNM504xx and USBQNM504xxC TVS arrays protect uni- and bi-directional lines, respectively. The new environmentally friendly, halogen-free solutions are offered in a non-ferrous, quad flat no-lead 143-pin metal lead frame. The RoHS-compliant "green" enclosure is also pin-for-pin compatible with SOT-143 packages. Additional features include:
-- Peak power rating of 500 watts for an 8/20 microsecond pulse.
-- Protection against electrostatic discharge (ESD) as defined in IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000-4-4 and effects of secondary lightning
-- Board level protection for sensitive circuitry including TTL, CMOS, DRAMs, SRAMs, HCMOS, HSIC microprocessors, and USB and I/O transceivers.
