DESCRIPTION
The 1.5KE series of high current uni/bi-directional transient suppressors are designed for A.C. line protection and high power DC bus clamping applications. These devices offer uni/bi-directional port protection from 6.8 volts to 600 volts. They provide a clamping voltage lower than the avalanche voltage. Therefore, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level. They can also be connected in series and/or parallel to create very high capacity protection solutions.
FEATURES
- Low incremental surge resistance.
- Excellent clamping capability.
- Color band denoted cathode except bidirectional.
- Typical IR less than 1μA above 11V.
- High temperature wave soldering: 265℃/10s at terminals.
- Plastic package has underwriters laboratory flammability 94V-0.
- 1500W peak pulse power capability at 10×1000μs waveform.
- Fast response time: typically less than 1.0ps from 0V to VBR min.
