1.5KE6.8

DESCRIPTION APPEARANCE

The Transient Voltage Suppressor (TVS) series for 1N5908 & 1N6267-1N6303A

are JEDEC registered selections for unidirectional devices. The popular series of

1.5KE6.8-1.5KE400CA offers similar voltages with an extended voltage range

and also provides bidirectional options with a C or CA suffix. All have the same

high Peak Pulse Power rating of 1500 W and extremely fast response time. They

can protect from secondary lightning effects per IEC61000-4-5 and class levels

described herein as well as inductive switching environments and induced RF

protection. Since their response time is virtually instantaneous, they can also

protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

NOTES: 1. Normal selection criteria for TVS devices is by rated stand-off voltage (VWM) and should be equal or greater than dc or continuous peak

operating voltage.

2. TVS devices are tested to maximum peak pulse current (IPP) with clamping voltage monitored. This surge capability is one of the most

significant electrical characteristics of the device and should be considered as part of customer quality inspections.

3. For Bidirectional part number add C or CA as suffix (e.e., 1.5KE33C or 1.5KE33CA). For Bidirectional types having VWM of 8 volts and

under, the ID leakage current is doubled. 1N62XX or 1N5908 not available as Bidirectional. For Bipolar capacitance will be .5 that shown in

Fig. 2 for zero bias.

4. For unidirectional, the forward voltage (VF) is 3.5 volts maximum at 100 Amps peak for 8.3 ms half-sine wave.
