NOTES:
(1) For bi-directional devices add “C” for ±10% and “CA” for ±5% tolerance of VBR
(2) VBR measured after IT applied for 300µs square wave pulse
(3) For bipolar devices with VR=10 Volts or under, the IT limit is doubled
APPLICATION NOTES
A 1500W (SMC) device is normally selected when the threat of transients is from lightning induced transients, conducted via external leads or I/O lines. It is also used to
protect against switching transients induced by large coils or industrial motors. Source impedance at component level in a system is usually high enough to limit the current
within the peak pulse current (IPP) rating of this series. In an overstress condition, the failure mode is a short circuit.
RECOMMENDED PAD SIZES
The pad dimensions should be 0.010” (0.25mm) longer than the contact size, in the lead axis. This allows a solder fillet to form, see figure below. Contact factory for
soldering methods
