SYMBOLS & DEFINITIONS

Symbol

Definition

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

Peak Pulse Current: The peak current during the impulse (See Figure 2)
