DESCRIPTION
The SMAJ series are TRANSIL TM diodes de-signed specifically for protecting sensitive equip-ment against transient overvoltages. The SMA package allows save spacing on high density printed circuit boards.
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 2: Absolute Maximum Rating (T amb = 25°C)Table 3: Thermal Resistances
