TYPICAL APPLICATIONS

3D Models

Use in sensitive electronics protection against voltage

transients induced by inductive load switching and lighting

on ICs, MOSFET, signal lines of sensor units for consumer,

computer, industrial, automotive, and telecommunication.

Package

(“_X” denotes revision code e.g. A, B, ...)

Terminals: matte tin plated leads, solderable per

J-STD-002 and JESD 22-B102

APPLICATION NOTES

M3 and HM3 suffix meet JESD 201 class 2 whisker test

• Respect thermal resistance (PCB layout) - as the

temperature coefficient also contributes to the clamping

voltage

Polarity: color band denotes cathode end

• Select minimum breakdown voltage, so you get

acceptable power dissipation and PCB tie point

temperature

• Devices with higher breakdown voltage will have a shorter

conduction time and will dissipate less power

• Clamping voltage is influenced by internal resistance -

design approximation is 7 V per 100 mA slope

• Keep temperature of TVS lower than TOPSwitch^®as a

recommendation

• Maximum current is determined by the maximum T_Jand

can be higher than 300 mA

• Contact supplier for different clamping voltage/

current arrangements

• Minimum breakdown voltage can be customized for other

applications. Contact supplier

• TOPSwitch is
