Feature
Current regulating diodes (CRD hereunder) are diodes that maintain a constant current flow despite voltage fluctuations. CRDs supply constant current over a wide range of voltage from less than 1V to 100V. Constant current is supplied regardless of fluctuations in voltage applied, load resistance changes and ripple voltage. Creating a constant current circuit generally involves multiple components, but with SEMITEC CRDs only one part is required to accomplish the same function.
- Pinch-off current (average): 8.20mA
- Max. rated voltage: 30V
Applications
- Constant current source for LED brightness stabilization
- LED street lights, LED fluorescent lamps, LED light bulbs, LED downlights

- 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
