SMT100 PDF datasheet
Refer to http://www.chinaicmart.com/series-SMT/SMT100.html
The electrical characteristics of a SMT100 device are similar to that
of a self-gated Triac, but the SMT100 is a two terminal device with no
gate. The gate function is achieved by an internal current controlled
mechanism.
Like the T.V.S. diodes, the SMT100 has a standoff voltage (Vrm) which
should be equal to or greater than the operating voltage of the system
to be protected. At this voltage (Vrm) the current consumption of the
SMT100 is negligible and will not affect the protected system.
When a transient occurs, the voltage across the SMT100 will increase
until the breakdown voltage (Vbr) is reached. At this point the device
will operate in a similar way to a T.V.S.device and is in avalanche
mode. |
