Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMSZ5265B-TP is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

• Zener Voltage (Nominal): 62 V
• Tolerance: ±5%
• Maximum Power Dissipation: 500 mW
• Impedance (Maximum): 185 Ohms
• Reverse Leakage Current: 100 nA @ 47 V
• Operating Temperature Range: -55°C to 150°C
• Package Type: SOD-123 surface mount
• Compliance Standards: RoHS3, REACH Unaffected

Substitute parts must match all electrical specifications and physical packaging requirements to ensure functional equivalence in circuit applications. The MMSZ5265BT1G from onsemi meets all specified parameters and is therefore a direct substitute.
