P6KE12CA-E3 TVS Diode PBS-26B 2A 250V Push Button Green It's a 680k ohm resistorThe P6KE TVS series is made to safeguard delicate equipment from electrostatic discharges in accordance with IEC 61000 4 2, MIL STD 883 Method 3015, and electrical stress in accordance with IEC 61000 4 4 and 5. For surges under 600 W 10 1000 s, they are employed. With low leakage current and high junction temperature needed to guarantee dependability and stability over time, this planar technology makes it compatible with high end equipment and SMPS.
