描述 Description

μClamp? TVS diodes are designed to protect sensitive

electronics from damage or latch-up due to ESD.

They features large cross-sectional area junctions for

conducting high transient currents. These devices

offer desirable characteristics for board level protection

including fast response time, low operating and

clamping voltage, and no device degradation.

The μClamp?2501ZA is constructed using Semtech’s

proprietary EPD TVS process technology. The EPD

process provides low operating voltages with significant

reductions in leakage currents and capacitance over

silicon-avalanche diode processes.

μClamp2501ZA is in a DFN 0.60x0.30x0.25mm 2-Lead

package. Each device will protect one line operating

at 2.5 volts. It gives the designer the flexibility to

protect single lines in applications where arrays are not

practical. The combination of small size and high ESD

surge capability makes them ideal for use in portable

applications such as cellular phones, tablets, and

notebook computers.
