1.  Non-repetitive current pulse, per Pulse Waveform graph and derated above TA = 25 °C per Pulse Derating Curve.
2.  Thermal Resistance Junction to Lead.
3.  8.3 ms Single Half-Sine Wave duty cycle = 4 pulses maximum per minute (unidirectional units only).
4.  Single Phase, Half Wave, 60 Hz, resistive or inductive load. For capacitive load, derate current by 20 %.

The markets of portable communications, computing and video equipment are challenging the semiconductor industry to develop 
increasingly smaller electronic components. 

Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection applications, in compact chip package DO-214AC (SMA) 
size format. The Transient Voltage Suppressor series offers a choice of Working Peak Reverse Voltage from 5 V up to 495 V and Breakdown 
Voltage up to 550 V. Typical fast response times are less than 1.0 ns for unidirectional devices and less than 5.0 ns for bidirectional devices 
from 0 V to Minimum Breakdown Voltage.
