Tektronix 80A09 26 GHz ESD Protection Device

Manufacturer: Tektronix
Model Number: 80A09
The Tektronix 80A09 is a DC-coupled voltage limiter that is used to protect sensitive electrical sampling module inputs from damage due to electric overload stress (EOS) and electrostatic discharge (ESD). Voltages greater than ± 2 V can damage the high-performance samplers (such as the 80E03 or 80E04) used in 8000 series sampling oscilloscopes. The 80A09 dramatically reduces the likelihood that such voltages will reach the sensitive high bandwidth sampling diodes in the electrical sampling module, ensuring that module measurement performance is not degraded.
