Microsemi Corp. / The diode experts SCOTTSDALE, AZ For more information call: (602) 941-6300 SANTA ANA, CA Features ECONOMICAL SERIES AVAILABLE IN BOTH UNIDIRECTIONAL AND BIDIRECTIONAL CONSTRUCTION 6.8 TO 400 VOLTS AVAILABLE 400 WATTS PEAK PULSE POWER DISSIPATION * QUICK RESPONSE Maximum Ratings Peak Pulse Power Dissipation at 25C: 400 Watts Steady State Power Dissipation: 1.0 Watt at T, = +75C at 3/8" Lead Length telamping (0 volts to Vigay Min.): Unidirectional < 1 x 10 -12 seconds; Bidirectional <5 x 10 9 seconds. Operating and Storage Temperature: -65 to +175C Application This TAZ is an economical molded product frequently used for automotive applications to protect voltage sensitive components from destruction or partial degradation. The response time for unipolar clamping action is virtually instantaneous (1 x 10-12 seconds). They have a peak pulse power rating of 400 watts for 1 ms as depicted in Figures 1 and 2. Microsemi also offers various other TAZ devices to meet higher and lower power demands and special applications.
