1KSMBJ series
1000W SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR
The 1KSMBJ range of surface mount protectors utilises the proven glass passivated technology used in
many of Littelfuse products portfolio. Rated at 1000 watts (10 x 1000 µs double exponential
waveform), the 1KSMBJ bridges the gap left by traditional types rated at 600 watts and 1500 watts,
suiting many applications where both power handling and size are paramount. The extremely fast
turn-on time, (less than one pico second), coupled with the low clamping factor and low on-state
impedance make this range ideal for the protection of today’s circuits. Our specially selected range of
voltages has been chosen to fulfill optimum protection for use in automotive and telecom
applications.
