Product Overview

This high-reliability surface mount Transient Voltage Suppressor (TVS) product family includes a rectifier diode

in series with and in the opposite direction to the primary TVS protection diode. The circuit being protected

sees only the rectifier diode's low 100 pF capacitance. They are available in either a DO-215AB (gull-wing)

or DO-214AB (J-bend) package, and RoHS compliant versions are available. The low capacitance of these TVS

devices allows them to be applied to the protection of high-frequency signal and communication lines in

inductive switching environments or systems exposed to the secondary effects of lightning per IEC61000-4-5,

as well as RTCA/DO-160G or ARINC 429 for airborne avionics. They also protect from ESD and EFT per

IEC61000-4-2 and IEC61000-4-4. If bipolar transient capability is required, two of these low capacitance TVS

devices may be used in parallel and opposite directions (anti-parallel) for complete AC protection (Figure 5-3).
