FEATURES:FEATURES:
• UNIDIRECTIONAL AND BIDIRECTIONAL SURFACE MOUNT TAZ
• 2000 WATTS PEAK POWER
• VOLTAGE RANGE: 5.0 TO 170 VOLTS
• LOW INDUCTANCE
• FOR SURFACE MOUNTING
DESCRIPTION: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.
MAXIMUM RATINGS:MAXIMUM RATINGS:
2000 watts if Peak Power dissipation (10 x 1000µµs)
Clamping (0 volts to V(BR) min): less than 1 x 10-12 seconds
(theoretical)
Forward surge rating: 200 Amps, 1/120 sec @ 25°°C (Excluding
Bidirectional)
Operating and Storage Temperature: -55°° to +150°°C
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.

Microsemi Corporation's HSMCJ Series (2000W) surface mountable packages are designed specifically for
transient voltage suppression. The wide leads assure a large surface contact for good heat dissipation, and a low
resistance path for surge current flow to ground. These high speed transient voltage suppressors can be used to
effectively protect sensitive components such as integrated circuits and MOS devices.
