Philips Semiconductors Product specification
Damper diode BY228
FEATURES
• Glass passivated
• High maximum operating
temperature
• Low leakage current
• Excellent stability
• Available in ammo-pack
• Also available with preformed leads
for easy insertion.
APPLICATIONS
• Damper diode in high frequency
horizontal deflection circuits up to
16 kHz.
DESCRIPTION
Rugged glass package, using a high
temperature alloyed construction.
This package is hermetically sealed
and fatigue free as coefficients of
expansion of all used parts are
matched.
