MICROCHIP LC64

This hermetically sealed Transient Voltage Suppressor (TVS) product family includes a rectifier diode element in series and in the opposite direction. This allows it to present a very low (<100 pF) capacitance to the system it is protecting. The low capacitance of these devices makes them particularly useful for protecting lines carrying high frequency signals. They are also useful in protecting from the secondary effects of lightning in airborne avionics per IEC61000 - 4 - 5, RTCA/DO - 160G, and ARINC 429. If bidirectional 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.

• Unidirectional low - capacitance TVS series for flexible thru - hole mounting.
• For bidirectional applications, use two in anti - parallel.
• Suppresses transients up to 1500 watts @ 10/1,000 μs.
• 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. RoHS compliant versions available.

• Protection from switching transients and induced RFI.
• Low capacitance for data line protection up to 1 MHz. Protection for fast data rate lines in aircraft up to: - RTCA/DO - 160G Level 5 Waveform 4 and Level 2 Waveform 5A (up to bit rates of 100 kb/s)
• ESD & EFT protection per IEC 61000 - 4 - 2 and - 4 - 4.
