Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition. (See Note 1 above.)
Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25
Maximum Clamping Voltage: The maximum peak voltage appearing across the TVS when subjected to the
peak pulse current in a one millisecond time interval. The peak pulse voltage is the combination of voltage rise
due to both the series resistance and thermal rise and positive temperature coefficient (
Peak Pulse Current: The peak current during the impulse (See Figure 2)
Peak Pulse Power: The pulse power as determined by the product of V
Standby Current: The current at the standoff voltage (V
Breakdown Current: The current used for measuring Breakdown Voltage (V
