SA5.0(C)A - SA170(C)A
Features
• Glass passivated junction. • 500W Peak Pulse Power capability on
10/1000 µs waveform.
• Excellent clamping capability. • Low incremental surge resistance. • Fast response time; typically less
than 1.0 ps from 0 volts to BV for unidirectional and 5.0 ns for bidirectional.
• Typical IR less than 1.0 µA above 10V.
