BZX784C6V2-TP Equivalent & Substitute Parts

Part Overview

The BZX784C6V2-TP is a Zener diode rated at 6.2 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 BZX784C6V2-TP is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage (Vz) must be 6.2 V nominal
• Reverse leakage current must not exceed 3 µA @ 4 V
• Impedance (Zzt) must not exceed 10 Ohms
• Forward voltage (Vf) must not exceed 900 mV @ 10 mA

Mechanical and Environmental Criteria:

• Surface mount mounting type required
• Operating temperature range must encompass or exceed -55°C ~ 150°C
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

Package Considerations:

• Primary package is SOD-723; alternative packages (SOD-523) are acceptable if electrical parameters remain within specification and board layout permits physical substitution

The CMOZ6V2 TR PBFREE meets all electrical equivalence criteria and environmental requirements, with the exception of package form factor (SOD-523 vs. SOD-723).

Parameter Comparison

Engineering Selection Recommendations

The CMOZ6V2 TR PBFREE is an active substitute for the obsolete BZX784C6V2-TP. Selection of this substitute is supported by the following factors:

Electrical Compatibility: All critical electrical parameters match or exceed the original specification. The CMOZ6V2 TR PBFREE provides identical zener voltage, impedance, reverse leakage current, and forward voltage characteristics. The tighter tolerance (±5% vs. ±6.45%) represents an improvement in voltage regulation accuracy.

Power Rating Enhancement: The substitute part provides 300 mW maximum power dissipation compared to 150 mW in the original part. This increased rating provides additional design margin and thermal headroom in applications where the original part was thermally constrained.

Environmental and Compliance Status: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. The substitute part supports an extended lower operating temperature limit (-65°C vs. -55°C), broadening the usable temperature range.

Product Status: The substitute part is active and maintains current production status, ensuring long-term availability and supply chain continuity.

Package Consideration: The primary difference is package form factor (SOD-523 vs. SOD-723). Physical board layout verification is required to confirm that the SOD-523 package footprint is compatible with the existing PCB design. If package substitution is not feasible, alternative sources or custom layout modifications may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the CMOZ6V2 TR PBFREE directly replace the BZX784C6V2-TP without circuit modification?

A: Electrical substitution is direct. The zener voltage, impedance, leakage current, and forward voltage are identical. No circuit modification is required from an electrical standpoint. However, physical board layout must accommodate the SOD-523 package footprint, which differs from SOD-723.

Q: What is the significance of the power rating difference (150 mW vs. 300 mW)?

A: The substitute part has twice the maximum power dissipation rating. This provides additional thermal margin and allows operation in applications with higher power dissipation requirements. Existing designs operating within the 150 mW limit will function without modification.

Q: Are there any tolerance differences that affect circuit performance?

A: The CMOZ6V2 TR PBFREE has a tighter tolerance (±5%) compared to the original part (±6.45%). This results in more precise zener voltage regulation and reduced voltage variation across production batches. This is a performance improvement for voltage reference and protection applications.

Q: What does the "TR PBFREE" designation indicate?

A: "TR" indicates Tape & Reel packaging format for automated assembly. "PBFREE" indicates lead-free (Pb-free) construction, consistent with RoHS3 compliance requirements.

Q: Is the extended temperature range (-65°C vs. -55°C) significant for my application?

A: The substitute part supports operation at 10°C lower minimum temperature. If your application operates at or near -55°C, the extended range provides additional margin. For applications within the original -55°C ~ 150°C range, this difference is not functionally significant.

Q: What is the primary limitation when substituting this part?

A: The package form factor change from SOD-723 to SOD-523 is the primary consideration. PCB footprint compatibility must be verified. If the existing PCB layout cannot accommodate SOD-523 dimensions, alternative sourcing or board redesign is required.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the BZX784C6V2-TP and CMOZ6V2 TR PBFREE are RoHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating.
