International Rectifier IR - S5V2P – Selenium Diode. 110VDC 250mA, New.

International Rectifier IR - S5V2P – Selenium Diode. 110VDC 250mA, New. The S5V2P is a vintage selenium transient voltage suppressor (diode) manufactured by International Rectifier, designed for circuit protection. It is characterized by its 8mm diameter and 13.5mm length (or approximately 0.380" diameter by 0.620" length, depending on the document) and was used for protecting circuits from voltage surges. Current ratings given are for intermittent operation with a maximum of 30 to 40 operations per second. If the frequency of operation exceeds 40 operations per second, a cell with a larger rating should be used and more information may be required in order to analyze the heating effect produced in the protector. Selenium diodes can be used to clip excess peak de voltages in circuits where some safe maximum peak-voltage amount must be assured. • Type: DC Cartridge Type, Relay and Switch Protector • Working Voltage: 89 VDC to 110 VDC • Maximum Coil Current: 0.25A (250mA) • Manufacturer: Primarily identified in older International Rectifier literature. • Dimensions: Roughly 0.380" Diameter x 0.620" Length. • Application: Voltage surge protection for electrical circuits. Selenium rectifiers rated for roughly 110 VDC at 250 mA were commonly used in vintage electronics (radios, TVs) from the 1950s and 1960s.
