For surface mounted applications in order to optimize  
board space  
·
·
·
·
Low profile package  
Built-in strain relief  
Glass passivated junction  
Low incremental surge resistance  
·
600W peak pulse power capability with a 10/1000μs  
Waveform, repetition rate (duty cycle): 0.01%  
Excellent clamping capability  
Fast response time: typically less than 1.0ps from 0 Volts to  
V (BR) for unidirectional and 5.0ns for bidirectional types
