Substitute Part Grouping Explanation

Substitute parts for the BZX79-B68,113 are identified based on electrical equivalence and mechanical compatibility. The substitution criteria are strictly limited to the following parameters:

  • Voltage - Zener (Nom) (Vz): 68 V
  • Tolerance: ±2%
  • Power - Max: 400 mW
  • Impedance (Max) (Zzt): 240 Ohms
  • Current - Reverse Leakage @ Vr: 50 nA @ 47.6 V
  • Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
  • Operating Temperature: -65°C ~ 200°C
  • Mounting Type: Through Hole
  • Package / Case: DO-204AH, DO-35, Axial
  • RoHS Status: ROHS3 Compliant
  • Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are electrically and mechanically interchangeable. Packaging format differences (Tape & Reel versus Cut Tape) do not affect functional equivalence.
