Demonstrating fixed output currents of 20 mA and 25 mA, respectively, Supertex’s CL520 and CL525 linear constant-current 2-terminal SSLDs demonstrate a dropout of 1 V. The RoHS-compliant devices are appropriate for general lighting applications employing single or multiple LEDs, such as decorative lighting and low-voltage signage or channel lighting. Both components offer temperature-compensated output currents to maintain consistent LED brightness regardless of temperature, maximum ratings of 90 V, and transient withstanding without any additional transient protection circuitry when used as recommended. CL520 and CL525 are available in TO-92 (CL520N3-G, CL525N3-G) and D-PAK (CL520K4-G, CL525K4-G) packages. Pricing starts at $0.33 (TO-92) and $0.47 (D-PAK) each in 1,000 quantities.
