Bourns Announces New Transient Voltage Suppressor Diodes for Surge and ESD Protection Applications

Riverside, Calif., March 24, 2010 Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced the introduction of four new ESD/EFT/Surge Protection series products designed to meet the space-constrained needs of portable communications, computing and video applications. The new transient voltage suppressor (TVS) diodes offer optimal protection for surge and ESD threats and are available in industry standard SMT package size formats. The new RoHS compliant* diodes comply with IEC 61000-4-2 ESD (Min. Level 4), IEC 61000-4-4 EFT, and IEC 61000-4-5 Surge industry standards. Bourns® chip diodes provide ease of manufacturability with standard pick and place equipment and the flat configuration minimizes roll away.

“Bourns designed its new series of discrete TVS diode products in response to growing customer demand for smaller components in a broad range of telecom, consumer, industrial, medical, audio and instrumentation applications,” said Ian Doyle, ESD protection product manager for Bourns. “Our new TVS diodes provide a good circuit protection solution for these applications while also meeting the highest industry standards.”

The new transient voltage suppressor diodes offer a choice of working peak reverse voltage from 5 Volts (V) up to 170 V and breakdown voltage up to 200 V. Below are additional details regarding the Bourns TVS diodes.
