DESCRIPTION
The popular Transient Voltage Suppressor series of M1.5KE6.8 – M1.5KE400CA with its various upscreening options offer an extended voltage range and provides a wide variety of commercial, high reliability, RoHS and bidirectional options. All have the same high peak pulse power rating of 1500 W and extremely fast response time. They can protect from secondary effects of lightning per IEC61000-4-5 and the class levels as shown below as well as voltage transients from inductive switching and RFI. Since their response time is virtually instantaneous, they also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

FEATURES
• High reliability devices with fabrication and assembly lot traceability
• Economical plastic encapsulated TVS series for thru-hole mounting
• 3σ lot norm screening performed on standby current (ID)
• 100% surge tested devices suppress transients up to 1500 watts @ 10/1000 µs (see figure 1)
• Enhanced reliability screening available in reference to MIL-PRF-19500. Refer to Hirel NonHermetic Product Portfolio for more details on the screening options. (See part nomenclature for all options.)
• Enhanced reliability source controlled devices have wafer fabrication and assembly lot traceability
• Moisture classification is “Level 1” with no dry pack required per IPC/JEDEC J-STD-020B
• RoHS compliant versions available
