C4

HV switch, variable on-time, low on-resistance, SiC & Trench FET  

Extremely low on-resistance by SILICON CARBIDE FET (SiC)* or Trench FET technology Versatile HV switch with true relay character On-time controllable by TTL signal  Low dynamic switching losses and extremely low turn-on losses Ideal for industrial power applications Robust regarding overload and voltage reversal Excellent dv/dt immunity against HV transients

 

* The newly introduced SiC products are partly not available in larger quantities before December 2016. Please consult BEHLKE for more information.  

Application Note I:  BEHLKE solid-state switches have extreme rise and fall times. If your application does not require the full switching speed we suggest you the use of the speed limiting option S-TT (rise & fall times slower by approx. 50%) in combination with the input low pass filter option LP. The speed limiting options help to minimize the high frequency difficulties typical for fast high voltage pulse circuits  (e.g. self oscillating, self re-triggering, ringing etc.) and simplify the EMC design in general.

Application Note II:  Fast solid-state switches are relatively sensitive for reverse currents from unclamped inductive load or from excessive wiring inductance. Reverse currents may turn-on the slow intrinsic (parasitic) FET diodes in an undefined way and can lead to a catastrophic switch failure especially during the turn-off phase in combination with high turn-off currents. Therefore it is recommended to combine FET switches always with a fast free-wheeling diode network (fast serial blocking diode + parallel fast free-wheeling diode), when inductive load or highly inductive wiring is connected to the switch. This protective diode network can be installed externally by means of single diodes of the series BEHLKE FDA. It can also be integrated into the switching module as option I-FWDN. Please read the general instructions carefully.

 Export Restrictions: Fast solid-state switches with a maximum peak current equal or higher than 500 Amperes are export restricted according to the United States law as well as the German law (dual use regulation). These goods must not be exported to third countries without a valid export permit of the US or German export authorities. An enduser statement may be required. Please consult BEHLKE.

Product Code: The model number contains coded information about voltage, current and turn-on behavior.  The first digits stand for the voltage in kV, the last digit before the dash indicates the turn-on behavior (0 = fixed on-time, 1 = variable on-time). The digits after the dash indicate the current  in Amperes x10. Special features are coded by the letters after a second dash. Example HTS 051-120-B:  HTS = HV Transistor Switch, 05 = 0.5 kV,  1 = variable on-time, 120 = 1200 Ampere, B = Low On-Resistance Trench FET  

Silicon Carbide (SiC) switches in LC2 technology. Robust and transient proof. Very low turn-on losses and in many cases no need for extra cooling measures thanks to extremely low on-resistance. Please scroll down for the options list.
