DESCRIPTION
The SMBJ series are TRANSILTM diodes designed
specifically for protecting sensitive equipment
against transient overvoltages.
Transil diodes provide high overvoltage protection
by clamping action. Their instantaneous response
to transient overvoltages makes them particularly suited to protect voltage sensitive devices
such as MOS Technology and low voltage supplied IC’s.

Note : The curves of the figure 3 are specified for a junction temperature of 25 ⊃C before surge.
The given results may be extrapolated for other junction temperatures by using the following formula :
∆VBR = αT * [Tamb -25] * VBR(25°C)
For intermediate voltages, extrapolate the given results.
