DESCRIPTION

· Current Regulating Diodes (CRDs) maintain a constant current flow despite voltage fluctuations.

· CRDs supply constant current over a wide range of voltages from less than 1V to 100V.

· SEMITEC CRDs simplify circuit design by requiring only one component to achieve constant current.

FEATURES

· Wide operating voltage range: less than 1V to 100V.

· Stable current output regardless of voltage fluctuations, load resistance changes, and ripple voltage.

· Available in both leaded (E series) and SMD (S series) types.

· Rated power: 300 mW for E series, 500 mW for S series.

· Operating temperature range: -30 to 150°C for E series, -40 to 150°C for S series.

· Junction temperature: up to 150°C.

· Various packing methods including axial taping and SMD reel taping.

APPLICATIONS

· Constant current source for LED brightness stabilization in LED street lights, fluorescent lamps, light bulbs, and downlights.

· Constant voltage circuit for supplying current to Zener diodes.

· Constant current source for proximity sensors and other sensors.

· Battery charge and discharge circuits.

· Electrolytic capacitor aging equipment.

· Constant current test equipment for various semiconductor devices.

· Telecommunications line interface.

· Earth leakage circuit breakers.

· Current source for piezoelectric actuators.

· Stabilized power supply circuits.
