Key Parameters

Substitute Part Grouping Explanation

Substitution of the DZ2S110M0L is determined by the following critical parameters:

Primary Matching Criteria:

• Zener voltage: 11 V nominal
• Package compatibility: SC-79 or SOD-523 surface mount packages
• Mounting type: Surface mount
• Moisture sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Factors:

• Power dissipation rating: Equal to or greater than 150 mW
• Zener voltage tolerance: ±2.5% or tighter
• Impedance (Zzt): 30 Ohms or lower
• Reverse leakage current: 50 nA @ 8 V or lower

Substitute parts meeting these criteria are functionally equivalent for direct replacement in applications where the original part specifications are required. Parts with higher power ratings or improved electrical characteristics remain compatible provided they maintain the same zener voltage and package form factor.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Equivalent Performance):

EDZVT2R11B (Rohm Semiconductor) and EDZVFHT2R11B (Rohm Semiconductor) are the closest functional equivalents to the DZ2S110M0L. Both maintain identical 150 mW power rating, 30 Ohms maximum impedance, and 11 V zener voltage. EDZVT2R11B offers ±2% tolerance with active product status and extended operating temperature range (-55°C to 150°C). EDZVFHT2R11B provides automotive-grade qualification (AEC-Q101) with ±2.09% tolerance and 150°C maximum junction temperature rating.

Higher Power Alternatives (Enhanced Capability):

BZT585B11T-7 (Diodes Incorporated) and BZX585-C11,135 (Nexperia USA Inc.) provide increased power dissipation capacity at 350 mW and 300 mW respectively, while maintaining 11 V zener voltage and SOD-523 package compatibility. BZT585B11T-7 features superior impedance (10 Ohms) and tighter tolerance (±2%). BZX585-C11,135 includes automotive qualification (AEC-Q100) and is suitable for automotive applications requiring higher reliability standards.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating. EDZVFHT2R11B and BZX585-C11,135 carry automotive-grade qualifications (AEC-Q101 and AEC-Q100 respectively) for applications requiring automotive reliability standards. EDZVT2R11B and BZT585B11T-7 are suitable for general industrial and consumer applications with active product status ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can BZT585B11T-7 replace DZ2S110M0L in all applications?

A: BZT585B11T-7 is electrically compatible as a direct replacement. The higher 350 mW power rating provides enhanced thermal margin. The lower 10 Ohms impedance improves voltage regulation performance compared to the original 30 Ohms specification. Package compatibility (SOD-523) is confirmed. Verify application thermal requirements do not depend on the original 150 mW power limitation.

Q: What is the difference between EDZVT2R11B and EDZVFHT2R11B?

A: Both parts share identical electrical specifications (11 V, 150 mW, 30 Ohms impedance, ±2% and ±2.09% tolerance respectively). EDZVFHT2R11B includes automotive-grade qualification (AEC-Q101) with maximum junction temperature of 150°C. EDZVT2R11B provides wider operating temperature range (-55°C to 150°C) without automotive qualification. Selection depends on application requirements for automotive compliance.

Q: Is BZX585-C11,135 suitable for automotive applications?

A: Yes. BZX585-C11,135 carries AEC-Q100 automotive qualification and is designated as automotive-grade. The part maintains 11 V zener voltage, SOD-523 package compatibility, and MSL 1 rating. The ±5% tolerance is wider than the original DZ2S110M0L specification; verify application voltage regulation requirements accommodate this tolerance.

Q: Why do some substitutes have higher reverse leakage current?

A: BZX585-C11,135 specifies 100 µA reverse leakage at 8 V, significantly higher than the original 50 nA specification. This characteristic is inherent to the device design and manufacturing process. Applications sensitive to reverse leakage current (such as precision analog circuits) should select alternatives with lower leakage specifications: EDZVT2R11B, EDZVFHT2R11B, or BZT585B11T-7 (all 100 nA or lower).

Q: Are all substitute parts available in the same package?

A: All substitute parts use SC-79 or SOD-523 package designations, confirming physical and electrical compatibility. Supplier device packages vary: BZT585B11T-7 and BZX585-C11,135 use SOD-523 tape and reel packaging; EDZVFHT2R11B and EDZVT2R11B use EMD2 supplier package. PCB footprints remain compatible across all alternatives.

Q: What is the inventory status of substitute parts?

A: EDZVT2R11B (Rohm) has the highest inventory at 21,400 pieces. BZT585B11T-7 (Diodes Incorporated) has 18,500 pieces. BZX585-C11,135 (Nexperia) has 10,883 pieces. EDZVFHT2R11B (Rohm) has 8,543 pieces. All parts are listed as active products with new original stock available.
