Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMSZ5263B-TP is determined by electrical and mechanical parameter equivalence. The following criteria establish substitution validity:

Electrical Parameters:

• Zener voltage (Nominal): 56 V
• Tolerance: ±5%
• Maximum power dissipation: 500 mW
• Maximum impedance: 150 Ohms
• Reverse leakage current: 100 nA @ 43 V
• Operating temperature range: -55°C to 150°C

Mechanical Parameters:

• Package type: SOD-123 surface mount
• Mounting configuration: Surface mount

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all electrical, mechanical, and compliance specifications are classified as direct substitutes. The MMSZ5263BT1G from onsemi satisfies all substitution criteria.
