DESCRIPTION

Transil

diodes

provide

high

overvoltage

protection

by

clamping

action.

Their

instantaneous reponse to transients makes them

praticularly suited to protect voltage sensitive

devices such as MOS Technology and low

voltage supplied IC’s.

MECHANICAL CHARACTERISTICS

.

Body marked with : Logo, Date Code, Type

Code and Cathode Band (for unidirectional

types only).

.

Full compatibility with both gluing and paste

soldering technologies.

.

Excellent on board stability.

.

Tinned copper leads.

.

High temperature resistant resin.
