ESD9DXXC

ESD9DXXC Series BI-Directional TVS for ESD Protection P b Lead(Pb)-Free General Description: The ESD9DXXC Series is designed to protect voltage sensitive components from ESD and transient voltage events. Excellent clamping capability, low leakage, and fast response time, make these parts ideal for ESD protection on designs where board space is at a premium. Because of its small size, it is suited for use in cellular phones, MP3 players, digital cameras and many other portable applications where board space is at a premium.

Pulse Waveform Fig2.Power Derating Curve Application Note Electrostatic discharge (ESD) is a major cause of failure in electronic systems. Transient Voltage Suppressors (TVS) are an ideal choice for ESD protection. They are capable of clamping the incoming transient to a low enough level such that damage to the protected semiconductor is prevented. Surface mount TVS offers the best choice for minimal lead inductance. They serve as parallel protection elements, connected between the signal lines to ground. As the transient rises above the operating voltage of the device, the TVS becomes a low impedance path diverting the transient current to ground. The ESD9DXXC Series is the ideal board evel protection of ESD sensitive semiconductor components. The tiny SOD-923 package allows design flexibility in the design of high density boards where the space saving is at a premium. This enables to shorten the routing and contributes to hardening against ESD. WEITRON http://www.weitron.com.tw 3/3 Rev.A 11-Aug-09
