HITACHI HZ2LL

HZ-LL Series
Silicon Epitaxial Planar Zener Diode for Hard Knee Low Noise
ADE-208-119A(Z)
Rev 1
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).
