ETC HZS-LLSERIES

HZS-LL Series
Silicon Epitaxial Planar Zener Diode for Hard Knee Low Noise
ADE-208-122A(Z)
Rev. 1
Dec. 1996
Features
• Vz-Iz characteristics are semilogarithmic linear from IZ=1nA to 1mA and have sharper breakdown
knees in a low current region, and also lower VZ temperature coefficients .
• Low dynamic impedance and low noise in the low current region (approximately 1/10 lower than the
current zeners).
• Suitable for 5mm-pitch high speed automatic insertion.
