Littelfuse SA22A

The SA Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

• 500N peak pulse capability at 10/1000μs waveform, repetition rate (duty cycles): 0.01%
• V @ T = V @25°C x (1+αT x (T - 25)) (αT:Temperature Coeffcient, typical value is 0.1% )
• Glass passivated chip junction in DO - 15 Package
• Fast response time: typically less than 1.0ps from 0 Volts to BV min
• Excellent clamping capability
• Typical failure mode is short from over - specifed voltage or current
• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
• IEC - 61000 - 4 - 2 ESD 30kV(Air), 30kV (Contact)
• ESD protection of data lines in accordance with IEC 61000 - 4 - 2
• EFT protection of data lines in accordance with IEC 61000 - 4 - 4
• Low incremental surge resistance
• Typical |R less than 1μΔ when VBR max>13V
• High temperature to refow soldering guaranteed: 260°C/40sec / 0.375"(9.5mm) lead length, 5 lbs., (2.3kg) tension
• Plastic package is fammability rated V - 0 per Underwriters Laboratories
• Matte tin lead–free plated
• Halogen free and RoHS compliant
• Pb - free E3 means 2nd level interconnect is Pbfree and the terminal finish material is tin(Sn) (IPC/ JEDEC J - STD - 609A.01)

• TVS devices are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuits used in telecom, computer, industrial and consumer electronic applications.
