C3

HV switch, variable on-time, low coupling capacitance, MOSFET  

● Versatile HV switch with true relay character ● On-time controllable by TTL signal ● Simplified EMC and reduced capacitive losses due to low coupling capacitance ● LC2 technology for highest transient immunity
Application Note I: The switches of the product group C3 are optimized regarding coupling capacitance against the control side and ground. A low coupling capacitance is the key to an efficient operation at high repetition rates. Reduced coupling capacitances are also desirable in view of low noise emission, good EMC behavior, stable operation and high switching speed. Both LC and LC2 switches fulfill these requirements very well. But if it is about highest switching frequencies (> 300 kHz), then the switches of series LC are the preferred choice. The disadvantage of the LC series is their limited transient immunity which makes them relatively sensitive for sparkovers, short circuits, unstable load and unstable input voltage. In opposite to that, the switches of the series LC2 are designed  for moderate switching frequencies (< 300 kHz) under harsh operating conditions. LC2 switches are insensitive for unstable load (e.g. plasma load) and for unstable input voltage. They can resist sparkovers, short circuits and overvoltage transients within their thermal capabilities.

Application Note II:  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 III:  Fast MOSFET 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) MOSFET 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 MOSFET 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 for details.

 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 31-12-LC:  HTS = HV Transistor Switch, 3 = 3 kV,  1 = variable on-time, 12 = 120 Ampere, LC = Low Coupling Capacitance.

Options (1)
 

 
B-CON Beginner's Configuration: The standard switch is equipped with various options to simplify first time experiments for users which are inexperienced with high voltage and high frequency circuit design. The beginner's configuration includes option FH and PT-HV for easy wiring and attachment without printed circuit boards, as well as option LS-C, LP and S-TT for an uncritical EMC behavior. Inexperienced users should also consider the combination with option I-PC or PC to avoid possible difficulties from the high voltage wiring and / or high frequency noise behavior.  (2)
