Fast Diodes Sorting by Shape:

Code designation

Example

DF 261 - 250 - 16 - M4 - N
1 2   3   4   5   7
Column  1  means DF = Stud Fast diode
Column  2  means Design version
Column  3  represents Average forward current, A
Column  4  represents Polarity:
  • X = Cathode to Stud;
  • no symbol = Anode to Stud;
Column  5  means Voltage code
Column  6  represents Group of reverse recovery time
Column  7  represents Ambient conditions: N=Normal; T=Tropical;
DF 123 - 320 - 12 - K4 - N
1 2   3   4   5   6
Column  1  means DF = Disc Fast diode
Column  2  means Design version
Column  3  represents Average forward current, A
Column  4  means Voltage code
Column  5  represents Group of reverse recovery time
Column  6  represents Ambient conditions: N=Normal; T=Tropical;
