S6X8ES SCR晶闸管 Littelfuse

S6X8ES  Thyristors

EV Series 0.8 Amp Sensitive SCRs

SCR Sen SCR 600V .8A 200uA

Description S6X8ES

New device series offers high static dv/dt and lower turn off (tq ) sensitive SCR with its small die planar construction design. It is specifically designed for GFCI (Ground Fault Circuit Interrupter) and Gas Ignition applications. All SCRs junctions are glass-passivated to ensure long term reliability and parametric stability.

Features S6X8ES

• RoHS compliant and Halogen-Free

• Thru-hole and surface mount packages

• Surge current capability > 10Amps

• Blocking voltage ( VDRM / VRRM ) capability - up to 800V

• High dv/dt noise immunity

• Improved turn-off time (tq ) < 25 μsec

• Sensitive gate for direct microprocessor interface

Applications  S6X8ES

The SxX8xSx EV series is specifically designed for GFCI (Ground Fault Circuit Interrupter) and gas ignition applications.

Design Considerations

Careful selection of the correct device for the application’s

operating parameters and environment will go a long way

toward extending the operating life of the Thyristor. Good

design practice should limit the maximum continuous

current through the main terminals to 75% of the device

rating. Other ways to ensure long life for a power discrete

semiconductor are proper heat sinking and selection of

voltage ratings for worst case conditions. Overheating,

overvoltage (including dv/dt), and surge currents are

the main killers of semiconductors. Correct mounting,

soldering, and forming of the leads also help protect

against component damage.
