Description

This surface mount Transient Voltage Suppressor SMCGLCE6.5 (TVS) product family includes a rectifier diode element in series and opposite direction to achieve low capacitance below 100 pF. They are also available as RoHS Compliant with an e3 suffix. The low TVS capacitance may be used for protecting higher frequency applications in inductive switching environments or electrical systems involving secondary lightning effects per IEC61000-4-5 as well as RTCA/DO-160D or ARINC 429 for airborne avionics. SMCGLCE6.5 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 6).
