The 7665A is a rugged hydrogen thyratron designed for use in compact military and civil radars. It has a ceramic envelope with a mounting flange and flying lead connections.

It features low jitter and low anode delay time and is suitable for use at high pulse repetition rates; it can switch peak powers up to 3 MW. The tube will operate over an ambient temperature range of 755 to +130 8C. A hydrogen reservoir is incorporated.

This tube of the 7665A was designed to comply with, and is electrically tested to, MIL-E-1/1485D.
