Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S360M0L is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - Zener (Nom): 36 V (exact match required)
• Mounting Type: Surface Mount
• Package / Case: SC-79, SOD-523 (physical compatibility)
• RoHS Compliance: Required for regulatory alignment

Secondary Compatibility Parameters:

• Power - Max: 150 mW or greater (equal or higher rating acceptable)
• Tolerance: ±2.5% or tighter (equal or tighter tolerance acceptable)
• Impedance (Max): 250 Ohms or lower (equal or lower impedance acceptable)
• Current - Reverse Leakage @ Vr: 50 nA or lower (equal or lower leakage acceptable)

Substitute parts meeting these criteria maintain functional equivalence within the electrical and mechanical constraints of the original design. Parts with higher power ratings, tighter tolerances, or lower impedance values provide equal or superior performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

EDZVFHT2R36B (Rohm Semiconductor)

This substitute provides the closest electrical match to the DZ2S360M0L. It maintains identical voltage (36 V), power rating (150 mW), and tolerance (±2.5%) specifications. The part is actively produced and carries ROHS3 compliance with AEC-Q101 automotive qualification. The EMD2 package is mechanically compatible with the original SC-79/SOD-523 footprint. Impedance is slightly higher at 300 Ohms versus 250 Ohms, and reverse leakage is marginally higher at 100 nA versus 50 nA, both within acceptable operational margins for most applications.

EDZVT2R36B (Rohm Semiconductor)

This alternative offers the same 36 V, 150 mW specifications with marginally relaxed tolerance (±3%). Active product status and ROHS3 compliance ensure supply continuity. The EMD2 package maintains mechanical compatibility. Operating temperature range extends to -55°C to 150°C, providing broader environmental coverage than the original part. Impedance and leakage characteristics are identical to EDZVFHT2R36B.

BZX585-C36,115 (Nexperia USA Inc.)

This substitute provides higher power dissipation capability (300 mW) with lower impedance (90 Ohms), delivering superior performance margins. Active product status and automotive-grade AEC-Q100 qualification ensure reliability. Tolerance is relaxed to ±5%, and reverse leakage remains at 50 nA. The SOD-523 package is directly compatible. This option is suitable for applications requiring enhanced thermal performance or lower output impedance.

SZMM5Z36VT1G (onsemi)

This part offers the highest power rating (500 mW) and lowest impedance (90 Ohms) among available substitutes, providing maximum performance headroom. Active production status and AEC-Q101 automotive qualification ensure supply and reliability. Tolerance is ±6%, and reverse leakage matches the original at 50 nA. The SOD-523 package is compatible. This option is appropriate for applications with elevated power dissipation requirements or demanding impedance specifications.

Frequently Asked Questions (FAQ)

Q: Can the DZ2S360M0L be directly replaced with any of these substitute parts?

A: All four substitute parts are electrically and mechanically compatible with the DZ2S360M0L. Each maintains the 36 V zener voltage and surface mount SOD-523 package configuration. Selection depends on specific application requirements regarding power dissipation, tolerance, and impedance characteristics.

Q: What is the significance of the power rating difference between the main part and substitutes?

A: The DZ2S360M0L is rated at 150 mW. Substitute parts with equal or higher power ratings (BZX585-C36,115 at 300 mW, SZMM5Z36VT1G at 500 mW) provide additional thermal margin and can dissipate higher power levels without exceeding junction temperature limits. Parts with equal 150 mW ratings (EDZVFHT2R36B, EDZVT2R36B) maintain the original thermal design point.

Q: How do tolerance differences affect circuit performance?

A: The DZ2S360M0L specifies ±2.5% tolerance. EDZVFHT2R36B matches this tolerance exactly. EDZVT2R36B offers ±3%, BZX585-C36,115 offers ±5%, and SZMM5Z36VT1G offers ±6%. Tighter tolerance ensures more precise voltage regulation. Applications requiring strict voltage accuracy should prioritize EDZVFHT2R36B or EDZVT2R36B.

Q: What does impedance (Zzt) represent, and why does it vary among substitutes?

A: Impedance (Zzt) characterizes the dynamic resistance of the zener diode at the specified test current. Lower impedance values (90 Ohms in BZX585-C36,115 and SZMM5Z36VT1G) result in better voltage regulation and lower output ripple. Higher impedance values (250-300 Ohms) are acceptable in applications with less stringent regulation requirements. The original part specifies 250 Ohms.

Q: Are all substitute parts RoHS compliant?

A: Yes. The DZ2S360M0L is RoHS Compliant. All four substitute parts carry ROHS3 Compliant status, ensuring compliance with current environmental and regulatory requirements.

Q: What is the difference between AEC-Q100 and AEC-Q101 qualifications?

A: Both are automotive-grade qualifications. AEC-Q100 applies to discrete semiconductors including diodes. AEC-Q101 is a specific qualification for discrete semiconductors. BZX585-C36,115 carries AEC-Q100 qualification. EDZVFHT2R36B and SZMM5Z36VT1G carry AEC-Q101 qualification. Both qualifications indicate automotive-grade reliability and testing standards.

Q: Can I use a substitute with higher power rating in place of the original?

A: Yes. A substitute with equal or higher power rating is functionally compatible. Higher power ratings provide additional thermal margin and do not degrade circuit performance. The physical package remains identical (SOD-523), ensuring PCB footprint compatibility.

Q: How does reverse leakage current affect circuit operation?

A: Reverse leakage current represents the small current flowing through the zener diode when reverse-biased below the zener voltage. The DZ2S360M0L specifies 50 nA @ 27 V. EDZVFHT2R36B and EDZVT2R36B specify 100 nA @ 27 V, which is marginally higher but acceptable for most applications. Lower leakage is preferable in high-impedance circuits or precision applications.

Q: Are the EMD2 and SSMini2-F5-B packages physically interchangeable?

A: Both packages conform to the SC-79 and SOD-523 standard footprints. The EMD2 designation (used by Rohm) and SSMini2-F5-B designation (used by Panasonic) represent manufacturer-specific package identifiers for the same industry-standard form factor. PCB footprints are compatible.

Q: Which substitute should I select for a new design?

A: For applications matching the original 150 mW specification with tight tolerance requirements, EDZVFHT2R36B is the optimal choice due to matching power rating and ±2.5% tolerance. For applications requiring enhanced performance margins, SZMM5Z36VT1G provides the highest power rating and lowest impedance. For cost-optimized designs with relaxed tolerance requirements, BZX585-C36,115 offers active production status and automotive qualification.
