* * * * * 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
SA5.0 thru SA170A
DESCRIPTION:
This Transient Voltage Suppressor is an economical, molded, commercial product used to protect voltage sensitive components from destruction or partial degradation. -12 The response time of their clamping action is virtually instantaneous (1 x 10 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.
