Substitute Part Grouping Explanation

Substitution of the ZMM5225B-13 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Zener (Nom): 3 V
• Tolerance: ±5%
• Power - Max: 500 mW
• Impedance (Max): 29 Ohms
• Current - Reverse Leakage @ Vr: 50 µA @ 1 V
• Operating Temperature Range: -65°C to 175°C (TJ)
• Package / Case: DO-213AA
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1N5225BUR-1/TR meets all critical electrical specifications and mechanical requirements. Both components are classified as Zener diodes with identical nominal voltage, power rating, impedance, and temperature operating range. Both are packaged in DO-213AA surface mount configuration and comply with RoHS3 requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1N5225BUR-1/TR manufactured by Microchip Technology is a direct parametric equivalent to the ZMM5225B-13. Both components share identical electrical specifications for Zener voltage, power dissipation, impedance, reverse leakage current, and operating temperature range. Both are packaged in DO-213AA surface mount configuration with MSL 1 rating.

The primary distinction between these components is product status: the ZMM5225B-13 is obsolete, while the 1N5225BUR-1/TR is active. The forward voltage specification of the 1N5225BUR-1/TR (1.1 V @ 200 mA) is lower than the ZMM5225B-13 (1.5 V @ 200 mA), which represents an improvement in forward conduction characteristics and does not compromise circuit compatibility.

The 1N5225BUR-1/TR is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. Selection of this substitute part ensures continued availability and support for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1N5225BUR-1/TR be used as a direct replacement for the ZMM5225B-13?

A: Yes. Both components meet identical specifications for Zener voltage (3 V), power rating (500 mW), impedance (29 Ohms), reverse leakage current (50 µA @ 1 V), and operating temperature range (-65°C to 175°C). Both are packaged in DO-213AA surface mount configuration. The lower forward voltage of the 1N5225BUR-1/TR does not create compatibility issues.

Q: What is the significance of the different product statuses?

A: The ZMM5225B-13 is classified as obsolete, indicating that Vishay General Semiconductor - Diodes Division no longer manufactures this component. The 1N5225BUR-1/TR is active, meaning Microchip Technology continues production and maintains supply availability. For new designs and ongoing production, the active substitute part is the appropriate selection.

Q: Are there packaging differences between these components?

A: Both components use the DO-213AA package for surface mount applications. The ZMM5225B-13 is specified as Mini MELF, while the 1N5225BUR-1/TR is specified as DO-213AA. These designations refer to the same physical package format. The 1N5225BUR-1/TR is supplied in Tape & Reel format, which is standard for automated assembly operations.

Q: How does the forward voltage difference affect circuit performance?

A: The 1N5225BUR-1/TR has a lower maximum forward voltage (1.1 V @ 200 mA) compared to the ZMM5225B-13 (1.5 V @ 200 mA). In forward conduction applications, this represents improved efficiency and reduced power dissipation. This characteristic does not create compatibility issues in voltage regulation or protection circuits.

Q: Are both components RoHS compliant?

A: The ZMM5225B-13 is specified as ROHS3 compliant. RoHS compliance information for the 1N5225BUR-1/TR is not provided in the available specifications. Verification of RoHS status with the supplier is recommended for applications with specific regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both components are rated MSL 1 (Unlimited), indicating unlimited shelf life without moisture control requirements. This simplifies storage and handling procedures for both the original and substitute components.
