Features
Description
The SMBJ series are TRANSIL™ diodes
designed specifically for protecting sensitive
equipment against transient overvoltages.
Transil diodes provide high overvoltage protection
by clamping action. Their instantaneous response
to transient overvoltages makes them particularly
suited to protect voltage sensitive devices such as
MOS Technology and low voltage supplied IC’s.
Table 1.
1. For a surge greater than the maximum values, the diode will fail in short-circuit.
