Substitute Part Grouping Explanation

Substitute parts for the BZX79-B13,113 are classified as parametric equivalents based on identical electrical and mechanical specifications. Substitution is valid when all of the following criteria are met:

• Voltage - Zener (Nom): 13 V
• Tolerance: ±2%
• Power - Max: 400 mW
• Impedance (Max): 30 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 8 V
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 10 mA
• Operating Temperature Range: -65°C to 200°C
• Mounting Type: Through Hole
• Package / Case: DO-204AH, DO-35, Axial

The substitute parts BZX79-B13,133 and BZX79-B13,143 meet all specified parameters and are therefore electrically and mechanically interchangeable with the main part number.
