Product specification

Controlled avalanche rectifiers

BAS11; BAS12

FEATURES

• Glass passivated

• High maximum operating

temperature

• Low leakage current

• Excellent stability

• Available in ammo-pack.

DESCRIPTION

Rectifier diodes in cavity free

cylindrical SOD91 glass packages,

incorporating Implotec

technology.

(1) Implotec is a trademark of Philips.

These packages are hermetically

sealed and fatigue free as coefficients

of expansion of all used parts are

matched.
