Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
1. FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint.
2. Thermal Resistance measurement obtained via infrared Scan Method.
**The “T1” suffix refers to an 8 mm, 7 inch reel.
The “T3” suffix refers to an 8 mm, 13 inch reel.

3. The type numbers shown have a standard tolerance of
±5%
on the nominal Zener voltage.
4. Nominal Zener voltage is measured with the device junction in thermal equilibrium at T
L
= 30°C
$1°C.
5. Z
ZT
and Z
ZK
are measured by dividing the AC voltage drop across the device by the ac current applied.
The specified limits are for I
Z(AC)
= 0.1 I
Z(dc)
with the AC frequency = 1 KHz.
