• Zener Voltage (Nominal): 7.5 V
• Voltage Tolerance: ±2%
• Maximum Power Dissipation: 500 mW
• Maximum Impedance: 6 Ohms
• Reverse Leakage Current @ 6 V: 3 µA
• Operating Temperature Range: -50°C to 150°C
• Package / Case: SOD-123
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all of these electrical and mechanical specifications are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the MMSZ5236A_R1_00001 be used as a direct replacement for the AMMSZ5236A-HF?

A: Yes. Both components meet identical electrical and mechanical specifications, including zener voltage, power rating, impedance, leakage current, temperature range, and package configuration. Direct substitution is supported by parametric equivalence.

Q: Are there differences in RoHS compliance between these parts?

A: No. Both the AMMSZ5236A-HF and MMSZ5236A_R1_00001 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the significance of the SOD-123 package for substitution?

A: SOD-123 is the specified surface mount package for both parts. This package designation ensures mechanical and thermal compatibility on PCB layouts designed for either component. No package conversion is required.

Q: Do these parts have different operating temperature ranges?

A: No. Both components operate across the identical temperature range of -50°C to 150°C (TJ).

Q: Is the forward voltage specification identical between these parts?

A: The AMMSZ5236A-HF specifies a maximum forward voltage of 900 mV @ 10 mA. This parameter is not provided for the MMSZ5236A_R1_00001 in the available data. Verification against the MMSZ5236A_R1_00001 datasheet is required if forward voltage characteristics are critical to circuit design.

Q: What is the impedance specification and why does it matter?

A: Both parts specify a maximum impedance (Zzt) of 6 Ohms. Impedance affects the dynamic response of the zener diode during transient conditions and is a key parameter for voltage regulation applications.

Q: Are there inventory considerations for selecting between these parts?

A: The MMSZ5236A_R1_00001 has 6376 units in stock compared to 921 units for the AMMSZ5236A-HF. Availability may influence component selection based on project lead time requirements.
