BZX784C5V1-TP Equivalent & Substitute Parts

Part Overview

The BZX784C5V1-TP is a Zener diode rated at 5.1 V nominal voltage with 150 mW maximum power dissipation in a surface mount SOD-723 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX784C5V1-TP is determined by the following critical parameters:

Electrical Compatibility:

• Zener voltage must match at 5.1 V nominal
• Impedance (Zzt) must be within acceptable limits at 60 Ohms maximum
• Reverse leakage current must not exceed 2 µA @ 2 V
• Forward voltage drop must not exceed 900 mV @ 10 mA

Thermal & Environmental Compatibility:

• Operating temperature range must encompass the application requirements
• RoHS3 compliance must be maintained
• Moisture sensitivity level must be compatible with assembly processes

Mechanical Compatibility:

• Surface mount mounting type is required
• Package footprint must be compatible with PCB design constraints

The CMOZ5V1 TR PBFREE meets these substitution criteria while offering enhanced specifications in power rating and temperature range, with active product status and higher inventory availability.

Engineering Selection Recommendations

The CMOZ5V1 TR PBFREE is a direct functional substitute for the BZX784C5V1-TP based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical nominal Zener voltage (5.1 V), impedance (60 Ohms maximum), reverse leakage current (2 µA @ 2 V), and forward voltage characteristics (900 mV @ 10 mA). The CMOZ5V1 TR PBFREE provides tighter voltage tolerance (±5% versus ±5.88%), which represents an improvement in specification consistency.

Power Rating Enhancement: The CMOZ5V1 TR PBFREE offers 300 mW maximum power dissipation compared to 150 mW in the original part. This increased rating provides additional thermal margin in applications without requiring circuit redesign.

Temperature Range Extension: The substitute part extends the lower operating temperature limit to -65°C, providing broader environmental compatibility while maintaining the same upper limit of 150°C.

Product Status & Compliance: The CMOZ5V1 TR PBFREE maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory alignment.

Package Consideration: The substitute uses SOD-523 package versus SOD-723. PCB layout verification is required to confirm footprint compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the CMOZ5V1 TR PBFREE directly replace the BZX784C5V1-TP in existing designs?

A: Electrical substitution is valid based on matching Zener voltage (5.1 V), impedance (60 Ohms), leakage current (2 µA @ 2 V), and forward voltage characteristics (900 mV @ 10 mA). PCB layout verification is required due to package differences (SOD-523 versus SOD-723).

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), power rating (150 mW versus 300 mW), voltage tolerance (±5.88% versus ±5%), operating temperature lower limit (-55°C versus -65°C), and package type (SOD-723 versus SOD-523).

Q: Does the higher power rating of the CMOZ5V1 TR PBFREE affect circuit performance?

A: No. The increased power rating (300 mW versus 150 mW) provides additional thermal margin without altering electrical performance. The component will operate identically in circuits designed for the original 150 mW specification.

Q: Are there compliance or regulatory differences between these parts?

A: Both components are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). No regulatory differences exist between the two parts.

Q: What must be verified before implementing the CMOZ5V1 TR PBFREE as a substitute?

A: PCB footprint compatibility must be confirmed due to package differences. The SOD-523 package dimensions differ from SOD-723. Verify that the PCB layout accommodates the substitute package geometry and that assembly equipment supports the new package type.

Q: Is the tighter voltage tolerance of the CMOZ5V1 TR PBFREE beneficial?

A: Yes. The ±5% tolerance specification is tighter than the original ±5.88%, providing improved voltage consistency across production batches and temperature variations.
