PROTECTION PRODUCTS - MicroClampTM
Description
The µClampTM series of TVS arrays are designed to protect
sensitive electronics from damage or latch-up due to ESD.
It is designed to replace multilayer varistors (MLVs) in por-
table applications such as cell phones, notebook comput-
ers, and PDAs. It features large cross-sectional area junc-
tions for conducting high transient currents. It offers
superior electrical characteristics such as lower clamp-
ing voltage and no device degradation when compared
to MLVs. They offer desirable characteristics for board
level protection including fast response time, low oper-
ating and clamping voltage, and no device degradation.
The µClampTM1201H is in a 2-pin, RoHS compliant,
SOD-523 package. The leads are finished with lead-
free matte tin. Each device will protect one line oper-
ating at 12 volts. It gives the designer the flexibility to
protect single lines in applications where arrays are not
practical. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2, Level 4 (15kV air, 8kV
contact discharge). The combination of small size and
high ESD surge capability makes them ideal for use in
portable applications such as cellular phones, digital
cameras, and MP3 players.
