UL RECOGNITION*
The entire series has
Underwriters Laboratory Recognition
for the classification of protectors (QVGV2) under the UL
standard for safety 497B and File #116110. Many competitors
only have one or two devices recognized or have recognition
in a non-protective category. Some competitors have no
recognition at all. With the UL497B recognition, our parts
successfully passed several tests including Strike Voltage
Breakdown test, Endurance Conditioning, Temperature test,
Dielectric Voltage-Withstand test, Discharge test and several
more.
Whereas, some competitors have only passed a flammabil-
ity test for the package material, we have been recognized for
much more to be included in their Protector category.
*Applies to 1.5KE6.8A, CA thru 1.5KE250A, CA
CLIPPER BIDIRECTIONAL DEVICES
1. Clipper-bidirectional devices are available in the 1.5KEXXA
series and are designated with a “CA” suffix; for example,
1.5KE18CA. Contact your nearest Motorola representative.
2. Clipper-bidirectional part numbers are tested in both direc-
tions to electrical parameters in preceeding table (except for
VF which does not apply).
3. The 1N6267A through 1N6303A series are JEDEC regis-
tered devices and the registration does not include a “CA”
suffix. To order clipper-bidirectional devices one must add
CA to the 1.5KE device title.
Devices listed in bold, italic are Motorola preferred devices.
