Description

The 1.5SMC540A is one member of the 1.5SMC series.The 1.5SMC series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Features of the 1.5SMC540A are:(1)low profile package with built-in strain relief for surface mounted applications;(2)glass passivated junction;(3)low incremental surge resistance;(4)low inductance;(5)excellent clamping capability;(6)1500W peak pulse power capability with a 10/1000s waveform, repetition rate (duty cycle): 0.01%;(7)very fast response time;(8)plastic package has underwriters laboratory flammability classification 94V-0.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.

The absolute maximum ratings of the 1.5SMC540A can be summarized as:(1)peak power dissipation with a 10/1000s waveform Pppm:1500W;(2)power dissipation on infinite heatsink, TA = 50°C Pm(av):6.5W;(3)peak forward surge current 8.3ms single half sine-wave uni-directional only Ifsm:200A;(4)thermal resistance junction to ambient air Rja:75°C/W;(5)thermal resistance junction to leads RJL:15 °C/W;(6)operating junction and storage temperature range TJ, TSTG:65 to +150 °C.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
