Product Information

Current Regulating Diodes (CRDs)

Current Regulating Diodes (CRDs)

Stockcode:

Where p.c.b. land area is limited, a single robust Semitec CRD can replace multiple components in space-critical applications. This simplifies product assembly and minimises component count and cost.
 
Semitec CRDs are constant current diodes and offer protection, stability and control when driving LED, optocoupler & battery-charging circuits.
 
With a choice of either axial leads or surface mount package styles, our CRDs will help to simplify your circuit design.
 
The S-series surface-mount range offers constant current values from 0.1mA to 18mA, the latest addition being a 22mA rated S-223T.
 
Semitec CRDs operate over a wide voltage range and can also be used as an excellent voltage reference in conjunction with a zener diode.

About us

UK's leading supplier of thermal components, ATC Semitec specialise in the field of thermal controls. Using our extensive product knowledge, we work with our customers to help them design-in and specify the optimum products from our ranges of NTC thermistors, PTC thermistors, temperature sensors, platinum RTD sensors,  thermostats or thermal fuses.  We carry extensive stocks and distribute circuit protection components such as Semifuse polymer PTC fuses, PEPI thermal cut-outs, SEFUSE thermal cut-offs and Semitec constant current diodes.

Based in Northwich, Cheshire we were established more than 25 years ago and are the UK’s leading thermal component supplier.  We only work with quality suppliers who are some of the leading manufacturers in the thermistor and thermostat industries including Semitec, Heraeus, PEPI, Asahi Keiki, EAW Relaistechnik, Fuzetec, NEC Schott, Matsuo Electric, SEKI & Thinking Electronics.  We operate as a one-stop shop for all your thermal protection needs.

Our range of NTC thermistors and temperature sensors provide high accuracy temperature sensing and control for electronic and programmable thermostats. While our PEPI thermostats, Asahi disc thermostats, Sefuse thermal fuses and bimetal thermal cut-outs offer cost-effective control and over-temperature protection.

Products include NTC Thermistors for temperature sensing, thermal control and temperature compensation; Temperature Sensors for accurate and reliable temperature control with IP67 or IP68 ratings; Bimetal Disc Thermostats for cost-effective temperature control and thermal protection; Thermal Fuses for ultimate product safety with over-temperature protection up to 280deg.C; PTC Thermistors for over-temperature protection and self-limiting PTC heaters; Circuit Protection Devices - Inrush limiters, current regulators, metal oxide varistors; Precision Bi-metal Thermostats - Incomparable performance from an electro-mechanical control; PTC Resettable Fuses - Polymer PTC over-current protection of batteries and circuits; Platinum Sensors - Pt100, Pt500 and Pt1000 elements and IP68 rated temperature sensors.

Our thermal components are readily available from stock for next-day delivery. Please visit the ATC Semitec website for more details or preferably call us for friendly expert technical advice.
