-24V Pass Element G825

Summary: This document is a 1969 schematic diagram from the Digital Equipment Corporation for the "-24V Pass Element G825" circuit. The circuit utilizes two parallel transistors (DEC3790-1) to regulate or pass power from a -30V source to various output points. It includes a 50μF, 50V capacitor for filtering and specified 5W, 5% resistors. The diagram also includes a transistor conversion chart noting that the DEC3790 corresponds to the 2N3790 industry standard.
