Transient Absorption
Zeners
DESCRIPTION:
This series of TAZ (transient absorption zeners) are available in surface
mountable packages to optimize board space. Packaged for use with
surface mount technology automated assembly equipment, these parts
can be placed on printed circuit boards and ceramic substrates to
protect sensitive components from transient voltage damage.
The HSMCJ series, rated for 2000 watts during a one millisecond pulse,
can be used to protect sensitive circuits against transients induced by
lightning and inductive load switching. With a response time of 1 x 10-12
seconds (theoretical), they are also effective against electrostatic
discharge and NEMP.

Note: A TAZ is normally selected according to the reverse "Stand Off
Voltage" (VRM) which should be equal to or greater than the dc or
continuous peak operating voltage level.
