TClamp1202P
Low Capacitance TClamp®
Surge Protection for 12V Interfaces
Description
TClamp®1202P provides dedicated surge and ESD
protection for RS-485 and other 12V lines in industrial
applications. It features high surge current capability
of 100A (tp=8/20s) and low clamping voltage making
them ideal for use in harsh transient environments.
This device is designed to replace mulitple discrete
components by integrating low capacitance, surgerated
compensation diodes with a high power transient
voltage suppressor (TVS). Capacitance is limited to
12pF maximum to ensure correct signal transmission
on high-speed lines. Each TClamp1202P may be used
to protect up to two lines. A voltage bus operating up
to 12V can also be optionally protected.
The TClamp1202P is in a 5-pin SLP2020P5 package,
measuring 2.0 x 2.0mm with a nominal height of
0.60mm. The ow- through package design simplies
PCB layout.
