MMBZ5259BV_R1_00001 Equivalent & Substitute Parts

Part Overview

The MMBZ5259BV_R1_00001 is a surface mount silicon zener diode manufactured by Panjit International Inc., rated at 39 V nominal zener voltage with 200 mW maximum power dissipation. This component is packaged in SOD-523 (SC-79) form factor and is designed for voltage regulation and protection applications in electronic circuits. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility. Substitute components must maintain the same nominal zener voltage, package type, and operating temperature range to ensure functional interchangeability within circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of zener diodes is determined by the following critical parameters:

Primary Matching Criteria:

• Nominal zener voltage (Vz): Must equal 39 V
• Package type: Must be SOD-523 (SC-79)
• Mounting type: Must be Surface Mount
• RoHS compliance: Must maintain ROHS3 status

Secondary Compatibility Factors:

• Operating temperature range: Substitute must cover or exceed the application temperature requirements
• Tolerance: Electrical tolerance of ±5% or better is acceptable
• Power rating: Substitute parts rated at 300 mW provide enhanced margin over the 200 mW requirement
• Impedance and leakage characteristics: Must be within acceptable circuit design parameters

All identified substitute parts maintain 39 V nominal zener voltage, SOD-523 packaging, surface mount configuration, and RoHS3 compliance. Substitute parts from Nexperia USA Inc. and Central Semiconductor Corp provide equivalent or superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

BZX585-B39,115 (Nexperia USA Inc.): This substitute part is qualified to AEC-Q100 automotive standards and carries Automotive grade designation. It provides tighter tolerance (±2% versus ±5%), enhanced power rating (300 mW versus 200 mW), and extended low-temperature operating range (-65°C versus -55°C). All compliance certifications match the original part. This option is suitable for applications requiring automotive qualification or enhanced performance margins.

BZX585-C39,115 (Nexperia USA Inc.): This substitute maintains identical tolerance (±5%) and operating temperature range (-65 to 150°C) to the original part while providing increased power dissipation capability (300 mW). Automotive grade and AEC-Q100 qualification are included. This option provides direct functional equivalence with improved thermal headroom.

CMOZ39V TR PBFREE (Central Semiconductor Corp): This substitute delivers matching tolerance (±5%) and extended operating temperature range (-65 to 150°C). Power rating is increased to 300 mW. All regulatory compliance requirements are met. This option provides cost-effective substitution with enhanced power handling capability.

All substitute parts maintain SOD-523 packaging, surface mount configuration, RoHS3 compliance, and REACH unaffected status. Selection among substitutes depends on application-specific requirements for tolerance, power margin, and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can BZX585-B39,115 be used as a direct replacement for MMBZ5259BV_R1_00001?

A: Yes. Both components share identical 39 V nominal zener voltage, SOD-523 package type, surface mount configuration, and RoHS3 compliance. The BZX585-B39,115 provides superior specifications including tighter tolerance (±2%), higher power rating (300 mW), and automotive qualification. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between BZX585-B39,115 and BZX585-C39,115?

A: The primary difference is tolerance specification. BZX585-B39,115 carries ±2% tolerance, while BZX585-C39,115 carries ±5% tolerance. Both share identical 39 V zener voltage, 300 mW power rating, SOD-523 package, and automotive qualification. Selection depends on circuit tolerance requirements.

Q: Are all substitute parts rated for the same operating temperature range?

A: The original MMBZ5259BV_R1_00001 operates from -55°C to 150°C. All three substitute parts extend the low-temperature limit to -65°C, providing broader operating range. The upper temperature limit of 150°C is maintained across all parts.

Q: Does the increased power rating of substitute parts affect circuit compatibility?

A: No. Higher power ratings (300 mW versus 200 mW) indicate enhanced thermal capability and do not affect circuit operation. The substitute parts remain functionally equivalent and can be used in circuits designed for the original 200 mW part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original MMBZ5259BV_R1_00001.

Q: Can CMOZ39V TR PBFREE be used in automotive applications?

A: CMOZ39V TR PBFREE is not designated as automotive grade and does not carry AEC-Q100 qualification. For automotive applications requiring qualification, BZX585-B39,115 or BZX585-C39,115 are the appropriate selections.

Q: What is the significance of the SOD-523 package designation?

A: SOD-523 (also designated SC-79) is the physical package type that determines board layout, footprint, and assembly compatibility. All listed parts use identical SOD-523 packaging, ensuring mechanical interchangeability on printed circuit boards.
