The HCPL-3120 comprises a GaAsP LED whereas the HCPL­­J312 and the HCNW3120 include an AlGaAs LED. The LED is optically coupled to an built-in circuit with an influence output stage. These optocouplers are ideally fitted to driving energy IGBTs and MOSFETs utilized in motor management inverter functions.

The excessive working voltage vary of the output stage gives the drive voltages required by gate-controlled units. The voltage and present equipped by these optocouplers make them ideally fitted to straight driving IGBTs with scores as much as 1200 V/100 A. For IGBTs with larger scores, the HCPL-3120 collection can be utilized to drive a discrete energy stage which drives the IGBT gate.

The HCNW3120 has the very best insulation voltage of VIORM=1414Vpeak within the IEC/EN/DIN EN 60747-5-2. The HCPL-J312 has an insulation voltage of VIORM=891Vpeak and the VIORM=630Vpeak can also be accessible with the HCPL-3120 (Option060)

The HCNR200/201 high-linearity analog optocoupler consists of a high-performance AlGaAs LED that illumi  nates two carefully matched photodiodes. The enter pho todiode can be utilized to observe, and subsequently stabilize, the sunshine output of the LED.

Because of this, the non-linearity and drift traits of the LED might be nearly elimi nated. The output photodiode produces a photocurrent that’s linearly associated to the sunshine output of the LED. The shut matching of the photodiodes and superior de signal of the package deal make sure the excessive linearity and steady achieve traits of the optocoupler.

The HCNR200/201 can be utilized to isolate analog indicators in all kinds of functions that require good stabil ity, linearity, bandwidth and low value.

The HCNR200/201 could be very versatile and, by acceptable design of the appli cation circuit, is able to working in many various modes, together with: unipolar/bipolar, ac/dc and inverting/ non-inverting. The HCNR200/201 is a wonderful answer for a lot of analog isolation issues.
