NOTE: The 1MHz damped oscillatory waveform (3) has an effective pulse width of 4
s. Equivalent peak pulse power at each of
the pulse widths represented in RTCA/DO-160E for waveforms 3, 4 and 5A (above) have been determined referencing Figure 1
herein as well as MicroNotes 104 and 120 (found on www.microsemi.com) and are listed below.

* Multiply by the conversion factor shown with reference to the maximum rated IPP in the Electrical Characteristics Table on page 2.
NOTE 1:
High current fast rise-time transients of 250 ns or less can more than triple the VC from parasitic inductance effects
(V= -Ldi/dt) compared to the clamping voltage shown in the initial Electrical Characteristics as also described in
Figures 5 and 6 herein
NOTE 2:
Also see MicroNotes 127, 130, and 132 on www.microsemi.com for further information on Transient Voltage
Suppressors with reference to aircraft industry specification RTCA/DO-160E.
