Littelfuse SM15-02HTG, Dual-Element Bi-Directional TVS Diode Array, 400W, 3-Pin SOT-23

The two-channel, general-purpose SM Series TVS Diode Array protects sensitive equipment from damage due to electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges. It can absorb repetitive ESD strikes without performance degradation and safely dissipate up to 24A of 8/20μs induced surge current with very low clamping voltages. SM Series TVS Diode Arrays are available in five voltage options: 5V, 12V, 15V, 24V, 36V

Very low dynamic resistance (RDYN): SM05: 0.19Ω, SM12: 0.25Ω, SM15: 0.30Ω, SM24: 0.50Ω, SM36: 0.65Ω
Robust surge protection: Peak pulse power: 400W (tP=8/20μs)
Enhanced ESD capability
Greatly reduces clamping voltages, ensuring modern ICs survive industry-defined electrical threats, such as ESD and lightning-induced surges
25% higher power handling capability than similar solutions offers more design margin to electrical threats as defined by industry standards
2-3 times higher ESD withstand capability than similar solutions, ensuring maximum reliability of equipment in the field
Ports (RS-232, RS-485, RS-422, RS-423, DC power)
A wide range of electronic equipment (industrial equipment, test and medical equipment, point-of-sale terminals, motor controls, security and alarm systems, keyboard, printer, microprocessor inputs)
