BZT52 Series
SILICON PLANAR ZENER DIODES
Standard Zener voltage tolerance is ±20%. Add
suffix “A” for ±10% tolerance and suffix “B” for
±5% tolerance, Other tolerance, non standard
and higher Zener voltages are upon request.

The Zener Impedance is derived from the 60 Hz AC voltage which results when an AC current having an RMS value equal to 10% of the
Zener Current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
.Zener Impedance is measured at two points to insure a sharp knee on the
breakdown curve and to eliminate unstable units.
2)
3)
Measured under thermal equilibrium and DC test conditions.
Tested with pulses tp = 20 ms.
