(DO-204AC)
October 2004
FEATURES
■Peak pulse power: 600 W (10/1000 µs )
■Stand-off voltage range 6.8 to 440V
■Unidirectional and Bidirectional types
■Low clamping factor
■Fast response time
■UL recognized
DESCRIPTION
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 5: The curves of the figure 4 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.
