E-272 Semitec 2.7mA 100V DO35 Axial Current Regulator Diodes (CRD)

CRDs offers a compact and reliable solution for keeping the current constant. The CRD E series products come in the DO-35 style package with DHD (double heat sink diode) construction. – Hermetically sealed, high reliability package – Suitable for mass production due to lower cost materials – Compact device offered in the DO-35 (300 mW) package 18mA CRD (E-183) With the addition of an 18mA CRD to our product lineup (up from 15mA), it is now possible to supply constant current to 20mA high brightness LEDs for luminance stabilization. SEMITEC’S CRD E series is fully compliant with RoHS DIRECTIVE2011/65/EU.

Applications

・Constant current source for LED brightness stabilization
・LED street lights, LED fluorescent lamps, LED light bulbs, LED downlights
・Constant voltage circuit for supplying constant current to Zener diodes
・Constant current source for proximity sensors and other sensors
・Battery charge / 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
