1000W Surface Mount Transient Voltage Suppressor
The 1KSMBJ range of surface mount protectors utilizes the
proven glass passivated technology used in many Littelfuse
product portfolios. Rated at 1000 watts (10 x 1000 s 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.
