Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM5Z36VT1G are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Package, Voltage, Power Rating): Parts that maintain the 36 V nominal voltage, 500 mW power rating, and SOD-523 package form factor. These substitutes differ primarily in tolerance specification and manufacturer qualification level. The SZMM5Z36VT1G is a direct equivalent with automotive-grade qualification (AEC-Q101).

Compatible Substitutes (Same Voltage, Different Power Rating or Package): Parts that maintain the 36 V nominal voltage but differ in maximum power dissipation or package type. These substitutes are suitable when circuit design permits lower power ratings or when alternative package geometries are acceptable. Substitution is valid when the application power requirement does not exceed the substitute part's maximum rating and when the package footprint is compatible with the PCB design.

Key Parameters Determining Substitution:

• Voltage - Zener (Nominal): Must equal 36 V
• Operating Temperature Range: Must encompass or match -65°C to 150°C
• Reverse Leakage Current: Must not exceed 50 nA @ 25.2 V or 27 V
• RoHS and REACH Compliance: Must maintain ROHS3 Compliant status
• Mounting Type: Must be Surface Mount

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: The SZMM5Z36VT1G is the primary direct equivalent to MM5Z36VT1G. Both parts maintain identical 36 V nominal voltage, 500 mW power rating, and SOD-523 package configuration. The SZMM5Z36VT1G carries automotive-grade qualification (AEC-Q101) and is suitable for applications requiring enhanced reliability standards. Tolerance specification differs at ±6% versus ±5.6%, which is acceptable for most voltage regulation circuits.

Compatible Substitute Selection for Reduced Power Applications: When circuit design permits lower power dissipation, the following substitutes are valid:

• BZX585-B36,115 and BZX585-C36,115 (300 mW, SOD-523 package): Suitable for low-power applications. Both carry automotive qualification (AEC-Q100). Maintain identical package footprint to MM5Z36VT1G.
• PZU36B,115 (310 mW, SOD-323F package): Automotive-qualified (AEC-Q100). Requires PCB layout modification due to different package geometry.
• CZRU52C36 (150 mW, 0603/SOD-523F package): Lowest power option. Operating temperature range limited to -55°C to 125°C. Suitable only for applications within this temperature window.

Compatible Substitute Selection for Higher Power Applications:

• BZX84J-B36,115 and BZX84J-C36,115 (550 mW, SOD-323F package): Exceed MM5Z36VT1G power rating. Both carry automotive qualification (AEC-Q101). Require PCB layout modification due to SOD-323F package geometry.

Automotive and Compliance Considerations: All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the original part specification. Automotive-qualified parts (AEC-Q100 or AEC-Q101) are available across multiple power ratings and package options, supporting design requirements for automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can SZMM5Z36VT1G replace MM5Z36VT1G in all applications? A: Yes. SZMM5Z36VT1G is a direct equivalent with identical electrical ratings (36 V, 500 mW) and package (SOD-523). The tolerance difference (±6% versus ±5.6%) and automotive qualification (AEC-Q101) make it suitable for all applications where MM5Z36VT1G is specified.

Q: What is the primary difference between MM5Z36VT1G and SZMM5Z36VT1G? A: SZMM5Z36VT1G carries automotive-grade qualification (AEC-Q101) and has a slightly wider tolerance specification (±6% versus ±5.6%). Electrical performance and package form factor are identical.

Q: Can I use BZX585-C36,115 instead of MM5Z36VT1G? A: BZX585-C36,115 is a compatible substitute only if circuit design permits 300 mW power dissipation instead of 500 mW. Both parts share the same 36 V nominal voltage, SOD-523 package, and -65°C to 150°C operating temperature range. Verify that the application power requirement does not exceed 300 mW.

Q: What is the impact of using a lower power-rated substitute? A: Lower power-rated substitutes (300 mW, 310 mW, or 150 mW) are valid only when the circuit's actual power dissipation requirement is within the substitute part's maximum rating. Exceeding the power rating will result in component failure or degraded performance.

Q: Can I use BZX84J-B36,115 in place of MM5Z36VT1G? A: BZX84J-B36,115 is electrically compatible (36 V, 550 mW, -65°C to 150°C) but uses a different package (SOD-323F versus SOD-523). PCB layout modification is required. The higher power rating (550 mW) is acceptable for applications designed for 500 mW or lower.

Q: Are all substitute parts RoHS and REACH compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the original MM5Z36VT1G specification.

Q: What is the significance of AEC-Q100 versus AEC-Q101 qualification? A: Both AEC-Q100 and AEC-Q101 are automotive reliability qualifications. AEC-Q101 applies to discrete semiconductors including Zener diodes. Parts carrying either qualification are suitable for automotive applications. The original MM5Z36VT1G carries no specific automotive qualification, while several substitutes (SZMM5Z36VT1G, BZX585 series, BZX84J series, PZU36B,115) carry AEC-Q100 or AEC-Q101 certification.

Q: Can CZRU52C36 be used in high-temperature applications? A: No. CZRU52C36 has an operating temperature range of -55°C to 125°C, which is narrower than MM5Z36VT1G (-65°C to 150°C). It is not suitable for applications requiring operation above 125°C or below -55°C.

Q: What package considerations apply when selecting a substitute? A: MM5Z36VT1G uses SOD-523 package. Direct substitutes maintaining SOD-523 (SZMM5Z36VT1G, BZX585 series, EDZVFHT2R36B) require no PCB layout changes. Substitutes using SOD-323F (BZX84J series, PZU36B,115) or 0603 (CZRU52C36) require PCB footprint modification and re-layout validation.

Q: Is impedance (Zzt) a critical parameter for substitution? A: Impedance affects voltage regulation stability and transient response. MM5Z36VT1G specifies 90 Ω maximum impedance. Substitutes with different impedance values (60 Ω or 300 Ω) may exhibit different dynamic performance. Verify impedance compatibility with circuit design requirements before substitution.
