ACE01508U

Low Capacitance Bidirectional Single Line TVS Protection Diode

VER 1.3

Description

The ACE01508U TVS protection diode is designed to replace multilayer varistors (MLVs) in portable

applications such as cell phones, notebook computers, and PDA’s. The device features large

cross-sectional area junctions for conducting high transient currents, offer desirable electrical

characteristics for board level protection, such as fast response time, lower operating voltage, lower

clamping voltage and no device degradation when compared to MLVs. The ACE01508U TVS protection

diode protects sensitive semiconductor components from damage or upset due to electrostatic discharge

(ESD) and other voltage induced transient events. The ACE01508U is available in DFN2 1.0×0.6

package with working voltages of 5 volt. It gives designer the flexibility to protect bidirectional single line in

applications where arrays are not practical. Additionally, it may be “sprinkled” around the board in

applications where board space is at a premium. It may be used to meet the ESD immunity requirements

of IEC 61000-4-2, ±30kV air, ±30kV contact discharge.
