5651 VR Tube

The 5651  (P/N 154-052, 154-0052-00, 154-0288-00) is an 87 V voltage reference tube with a miniature B7G 7-pin base. The 5651WA is a ruggedized version.

Nominal current is 1.5–3.5 mA. The 0G3/85A2 is similar with identical pinout but has a wider current range and slightly lower but tighter voltage specification.

Tek part number: 154-0052-00 (5651), 154-0288-00 (5651WA)
