J500 SERIES CURRENT REGULATING DIODES

Category: Diodes, Electronics, Linear Integrated Systems Inc

Overview

The J500 Series Current Regulating Diodes are precision devices presented by Linear Integrated Systems aiming to offer consistent current regulation across a wide spectrum, specifically between 0.192 to 5.6mA. These diodes are designed to replace Siliconix/Vishay J500 series and claim a strong foundation of “Twenty-Five Years Of Quality Through Innovation.”

Absolute Maximum Ratings

The diodes’ durability under various conditions is quantified through its maximum ratings at a standard temperature of 25°C (unless otherwise stated). The maximum storage and junction operating temperatures range from -55 to 150°C. The maximum power dissipation is marked at 350mW, with a continuous power. The datasheet outlines a forward current allowance of 20mA and a reverse current of 50mA. Furthermore, the peak operating voltage (Pov) can reach up to 50V.

Common Electrical Characteristics

The diodes exhibit a peak operating voltage (Pov) of 50V, assuming the current is 1/1/F(max). With a reverse voltage (Vr) of 0.8V at In=1mA and a forward capacitance (Cf) of 2.2pF under the conditions of Vf=25V and a frequency of 1MHz, these diodes maintain stability in operation.

Specific Electrical Characteristics

Characteristics such as forward current (IF), dynamic impedance (Zd), knee limiting voltages (VL), and impedance (Zk) are delineated with specific minimum, typical, and maximum values across a range of conditions. For instance, the dynamic impedance at 25°C when Vf equals 6V typically lies at values between 0.19Ω to 4.2Ω, depending on the part number. Notably, the IF ranges given are from a minimum of 0.192mA to a maximum of 5.6mA across the series from part numbers J500 to J511.

Part Variations

The datasheet details a series of part numbers (J500 to J511) each attributed with unique electrical characteristics pertaining to forward current (IF), dynamic impedance, and other critical parameters, providing a wide selection to accommodate various circuitry requirements.
