Input Transient Voltage Protection  
Fuse and Reverse Polarity Protection  
In many applications transient voltages on the converter input  
are always possible. These may be caused for example by  
short circuits between Vi+ and Vi–, where the network  
inductance may generate high energy pulses.  
The suppressor diode on the input also protects against  
reverse polarity input voltage. An external fast fuse is required  
to limit this reverse current; see table below.  
In order to protect the converter, a transient voltage sup-  
pressor diode is fitted at the input; see table below.

If transients generating currents above the peak pulse current  
IPP are possible, an external limiting network such as the circuit  
shown in figure 8 is recommended. It provides compliance with  
transients according to IEC/EN 61000-4-5, level 2. The comp  
onents are specified in table 5.  
If 40IMX4 converters should withstand 150 V transients  
according to 19Pfl1, the same external circuitry with similar  
components as shown in figure 8 can be used.
