Substitute Part Grouping Explanation

Substitution of the MMBZ5259BT-7-G is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Zener voltage rating: 39 V nominal
• Power dissipation: 150 mW maximum
• Voltage tolerance: ±5%
• Package type: SOT-523 surface mount
• Impedance (Zzt): 80 Ohms maximum
• Reverse leakage current: 100 nA @ 30 V
• Forward voltage: 900 mV @ 10 mA maximum
• Operating temperature range: -65°C to 150°C

The MMBZ5259BT-7-F is a direct substitute manufactured by Diodes Incorporated with identical electrical specifications and package configuration. This part maintains full compatibility with designs originally specified for the MMBZ5259BT-7-G, with the distinction that MMBZ5259BT-7-F is in active production status.
