Description
1N5819 DIODE SCHOTTKY AXIAL THL 40V 1A — BOLTON SKU 60652.
About the 1N5819 Schottky Diode, 40
The 1N5819 is an industry-standard Schottky barrier rectifier rated at 40 V repetitive peak reverse voltage and 1.0 A average forward current, supplied in the axial-leaded DO-41 plastic package for through-hole assembly. A Schottky uses a metal-to-silicon junction rather than a conventional PN junction, which gives it two defining characteristics: a lower forward voltage drop than a standard silicon rectifier, specified by Vishay at 0.60 V maximum at 1.0 A, and effectively no stored minority-carrier charge, so reverse recovery is close to instantaneous. Manufacturer datasheets for the part describe guard-ring die construction for transient protection together with high surge capability. Multiple manufacturers produce to this part number, so if a specific source or datasheet revision is required it should be named on the enquiry.

Typical applications
Schottky rectifiers of this rating are used for low-voltage rectification, freewheeling across inductive loads, reverse-polarity protection and output rectification in switch-mode supplies, where the reduced forward drop limits conduction loss. They appear across avionics support equipment, UAV power boards, instrumentation and general electronics repair, and are a common line item for board-level rework and spares kits.
