FEATURES:
ECONOMICAL SERIES
AVAILABLE IN BOTH UNIDIRECTIONAL AND BI-DIRECTIONAL CONSTRUCTION
5.0 TO 170 STAND-OFF VOLTAGE AVAILABLE
500 WATTS PEAK PULSE POWER DISSIPATION
QUICK RESPONSE
DESCRIPTION:
This Transient Voltage Suppressor is an economical, molded, commercial product
used to protect voltage sensitive components from destruction or partial degradation.
The response time of their clamping action is virtually instantaneous (1 x 10-12
seconds) and they have a peak pulse power rating of 500 watts for 1 ms as depicted in
Figure 1 and 2. Microsemi also offers a great variety of other Transient Voltage
Suppressor's to meet higher and lower power demands and special applications.
MAXIMUM RATINGS:
Peak Pulse Power Dissipation at 25°C: 500 Watts
Steady State Power Dissipation: 2.5 Watts at TL = +75°C
3/8" Lead Length
tclamping (0 volts to BV Min.):
Unidirectional <1x10-12 Seconds: Bi-directional <5x10-9 Seconds.
Operating and Storage Temperature: -55° to +175°C
