LC80A/TR [Microchip]

This hermetically sealed Transient Voltage Suppressor (TVS) product family includes a rectifier diode element in series and opposite direction to achieve low capacitance performance below 100 pF (see Figure 2). The low level of 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. With virtually instantaneous response, 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 in opposite directions (anti-parallel) for complete ac protection as shown in Figure 4

Unidirectional low-capacitance TVS series for flexible thru-hole mounting.

• For bidirectional applications, use two in anti-parallel (see Figure 4).
• Suppresses transients up to 1500 watts @ 10/1000 µs (see Figure 1).
• Clamps transients in less than 100 pico seconds (theoretical for unidirectional).*
• Working voltage (VWM) range 6.5 V to 170 V.
• 5% and 10% tolerance versions available.
• Hermetic sealed DO-13 metal package.
• Screening options available in reference to MIL-PRF-19500. (See Part Nomenclature for all available options.)
• RoHS compliant versions available.
