SYMBOLS AND DEFINITIONS
Symbol
Definition
VWM
Standoff voltage: Applied reverse voltage to assure a nonconductive condition
V(BR)
Breakdown voltage: The breakdown voltage of the device will exhibit at 25°C
Maximum clamping voltage: The maximum peak voltage appearing across the TVS when subjected to the peak pulse
VC
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
IPP
Peak pulse current: The peak current during the impulse
PPP
Peak pulse power: The pulse power as determined by the product of VC & IPP
ID
Standby current: The current at the standoff voltage (VWM)
I(BR)
Breakdown current: The current used for measuring breakdown voltage (V(BR))
