Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX84C36TS-7-F is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Zener voltage (nominal): 36 V
• Configuration: 3 independent channels
• Package type: SOT-363 (6-TSSOP)
• Power dissipation: 200 mW per element
• Operating temperature range: -65°C to 150°C
• Mounting type: Surface mount

Allowable Variation Parameters:

• Tolerance: ±6% (main part) to ±5% (substitute) — tighter tolerance is acceptable
• Impedance (maximum): 90 Ohms (main part) to 70 Ohms (substitute) — lower impedance is acceptable
• Reverse leakage current: 100 nA @ 25.2 V (main part) to 100 nA @ 27 V (substitute) — equivalent specification at different reference voltage

Compliance Requirements:

• ROHS3 compliance maintained
• MSL rating: 1 (Unlimited)
• REACH unaffected status

The MMBZ5258BTS-7-F meets all mandatory criteria and demonstrates improved electrical characteristics in tolerance and impedance, making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The MMBZ5258BTS-7-F is the direct functional equivalent for the obsolete BZX84C36TS-7-F. Selection of the substitute part is based on the following engineering factors:

Product Status: The BZX84C36TS-7-F is classified as obsolete, creating supply chain risk for ongoing production and new designs. The MMBZ5258BTS-7-F maintains active product status with Diodes Incorporated, ensuring long-term availability and manufacturing continuity.

Electrical Equivalence: Both parts share identical nominal zener voltage (36 V), power dissipation (200 mW), configuration (3 independent channels), and operating temperature range (-65°C to 150°C). The substitute exhibits improved tolerance specification (±5% versus ±6%) and lower maximum impedance (70 Ohms versus 90 Ohms), both of which represent enhanced electrical performance without introducing incompatibility.

Mechanical and Packaging Compatibility: Both parts utilize the SOT-363 (6-TSSOP) surface mount package, enabling direct PCB footprint compatibility without layout modifications.

Regulatory Compliance: Both parts maintain ROHS3 compliance, unlimited MSL rating, and REACH unaffected status, satisfying current environmental and regulatory requirements.

Packaging Format: The BZX84C36TS-7-F is supplied in standard packaging, while the MMBZ5258BTS-7-F is supplied in Tape & Reel (TR) format. This difference does not affect electrical or mechanical compatibility and reflects standard manufacturing practices for active products.

Frequently Asked Questions (FAQ)

Q: Can the MMBZ5258BTS-7-F be used as a direct replacement for the BZX84C36TS-7-F in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 36 V nominal zener voltage, 200 mW power dissipation, 3 independent configuration, and SOT-363 package. The substitute exhibits improved tolerance and impedance specifications, which do not introduce incompatibility.

Q: What is the significance of the tolerance difference (±6% versus ±5%)?

A: The MMBZ5258BTS-7-F provides tighter tolerance specification, meaning zener voltage will remain closer to the 36 V nominal value across the specified operating range. This represents improved performance and does not create compatibility issues with designs specified for ±6% tolerance.

Q: Does the lower impedance of the MMBZ5258BTS-7-F (70 Ohms versus 90 Ohms) affect circuit operation?

A: Lower impedance is a favorable characteristic that does not introduce incompatibility. It indicates improved voltage regulation performance and lower dynamic resistance, which benefits circuit stability.

Q: Are the package dimensions identical between both parts?

A: Yes. Both parts use the 6-TSSOP (SOT-363) package, which specifies identical physical dimensions, pin configuration, and PCB footprint. No layout modifications are required.

Q: Why is the BZX84C36TS-7-F classified as obsolete?

A: Obsolescence reflects the manufacturer's decision to discontinue production in favor of active alternatives such as the MMBZ5258BTS-7-F. The MMBZ5258 series represents the current production line for this functional category.

Q: What is the difference between standard packaging and Tape & Reel (TR) format?

A: Tape & Reel format is the standard supply method for high-volume surface mount production, providing components on continuous carrier tape suitable for automated assembly equipment. Standard packaging typically refers to alternative formats. This difference does not affect electrical or mechanical performance.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the BZX84C36TS-7-F and MMBZ5258BTS-7-F are ROHS3 compliant and carry unlimited MSL rating, satisfying current environmental and moisture sensitivity requirements.

Q: Can the MMBZ5258BTS-7-F be used in new designs?

A: Yes. The MMBZ5258BTS-7-F is classified as active product status, making it the appropriate choice for new designs requiring a 36 V, 200 mW, 3-channel zener diode array in SOT-363 package.
