DESCRIPTION

APPEARANCE

Microsemi’s 100 kW Transient Voltage Suppressors (TVSs) are designed

for aircraft applications requiring high power transient protection with a

comparatively small axial-leaded package size. This includes various

threats such as “Waveform 4” at 6.4/69 µs per RTCA/DO-160E Section 22.

It is also available with screening in accordance with MIL-PRF-19500 or

avionics screening as described in the Features section herein. It may also

be optionally acquired with RoHS Compliant (annealed matte-Tin finish)

with an e3 suffix added to the part number. Microsemi also offers a broad

spectrum of other TVSs to meet your needs.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

NOTE: This P_PPversus

time graph allows the

designer to use these parts

over a broad power

spectrum using the

guidelines illustrated in

App Note 104 on

Microsemi’s website.

Aircraft transients are

described with exponential

decaying waveforms. For

suppression of square-

wave impulses, derate

power and current to 66%

of that for exponential

decay shown in Figure 1.

INSTALLATION

TVS devices used across power lines are

subject to relatively high magnitude surge

currents and are more prone to adverse

parasitic inductance effects in the mounting

leads. Minimizing the shunt path of the lead

inductance and their V= -Ldi/dt effects will

optimize the TVS effectiveness. Examples

of optimum installation and poor installation

are illustrated in figures 3 through figure 6.

FIGURE 3

FIGURE 5

Figure

illustrates minimal parasitic

inductance with attachment at end of device.

Inductive voltage drop is across input leads.

Virtually no “overshoot” voltage results as

illustrated with figure 4.

The loss of

effectiveness in protection caused by

excessive parasitic inductance is illustrated

in figures 5 and 6. Also see MicroNote 111

for further information on “Parasitic Lead

Inductance in TVS”.
