NOTE: The 1MHz damped oscillatory waveform (3) has an effective pulse width of 4 μs. 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 Application Notes 104 and 120 (found on

Microsemi’s website) 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: 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 on page 1 as also described in Figures 5 and 6 herein.

Also see MicroNotes 127, 130, and 132 on the Microsemi website (Support section) for further information on Transient

Voltage Suppressors with reference to aircraft industry specification RTCA/DO-160E.
