HV switch, variable on-time, push-pull, MOSFET  

HV push-pull switch in halfbridge configuration  ● Two switching paths for fast rise and fall time Safe operation due to passive switching path locking No cross-over current Ideal for precise HV square wave pulses into capacitive load No working resistor required No necessity for large HV input energy storage capacitors
CAUTION:  Fast push-pull switches (half bridges) are very sensitive for reverse currents from inductive load or from increased wiring inductance. Reverse currents may turn-on the intrinsic (parasitic) MOSFET diodes in an undefined way. This can lead to a short circuit within the bridge switching paths with the further result of a catastrophic failure. Please always make sure that no current swings back into the output of switch. This should be verified by oscilloscope measurements at max. 10% of the actual operating voltage. Please connect always sufficient buffer capacitors (preferably ceramic types) directly to the HV inputs and use sufficient series damping resistors in case of long output wiring. Inductive load on MOSFET switches requires always a fast free-wheeling diode network (serial blocking diode + parallel free-wheeling diode). 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.

Technical Note: 
BEHLKE push-pull 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. These options help to minimize the high frequency difficulties typical for fast high voltage pulse circuits  (e.g. self oscillating or self re-triggering) and simplify the EMC design in general. 

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 31-03-HB-C:  HTS = HV Transistor Switch, 3 = 3 kV,  1 = variable on-time, 03 = 30 Ampere, HB = Half Bridge, C = Compact Series.

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)
