THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT

ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000

Notes

(1) The products are certified according to cULus (E332800), and VDE/IEC (40002622). See Agency Approval section for certificate download

(2) The sinusoidal voltage is assumed as the normal operating condition. If a non-sinusoidal voltage is present, type selection should be based on

multiplying the peak voltage by a factor of 0.707.

(3) The voltage measured at 1 mA meets the requirements of IEC 61051.

The tolerance on the voltage at 1 mA is ± 10 %.

(4) High energy surges are generally of longer duration. The maximum energy for one pulse of 10 x 1000 μs is given as a reference for longer

duration pulses. This pulse can be characterized by peak current (Ip) and pulse width t2 (virtual time of half Ip value, following IEC 60060-2,

section 6 ). If Vp is the clamping voltage corresponding to Ip, the energy absorbed in the varistor is determined by the formula:

where K is dependent on the value of t2 when the value of t1 is between 8 μs and 10 μs (see Peak Current as a Function of Pulse Width

drawing)

(5) A current wave of 8 x 20 μs is used as a standard for pulse current and clamping voltage ratings. The maximum non-repetitive transient current

is given for one pulse applied during the life of the component.

(6) For composition of the SAP part number:

Replace “x” by

B for bulk type

Replace “y” by S

for straight leads

T for tape and reel

F

for straight leads with flange (bulk only)

A for tape and ammopack

G

for straight leads with flange and H0 = 16 mm (tape and reel/ammo)

H

for straight leads with flange and H0 = 18.25 mm (tape and reel/ammo)

K

for kinked leads (bulk only)

L

for kinked leads with H0 = 16 mm (tape and reel/ammo)

M for kinked leads with H0 = 18.25 mm (tape and reel/ammo)

(7) All varistors are UL 1449 edition 4 recognized as SPD type 5 (component level) for operating temperatures up to 85 °C. The varistors may be

used in other SPD types as 2, 3, or 4 depending on the indicated IN nominal discharge current ratings. The final acceptance of the component

is dependent upon its installation and use in complete equipment submitted to underwriters laboratories Inc.
