MAZS360GML Equivalent & Substitute Parts

Part Overview

The MAZS360GML is a 36 V, 150 mW Zener diode manufactured by Panasonic Electronic Components in the SSMini2-F4 surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The part operates with ±3% voltage tolerance and is suitable for voltage regulation and protection applications in surface mount designs.

Substitute Part Grouping Explanation

Substitution of the MAZS360GML is determined by the following critical parameters:

Primary Matching Criteria:

Zener voltage: 36 V nominal
Surface mount technology
Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Factors:

Power dissipation capacity (150 mW minimum required)
Voltage tolerance (±3% to ±5% acceptable)
Impedance characteristics
Reverse leakage current specifications
Package compatibility (SOD-523, SOD-323F, SOD-123F acceptable)

Substitute parts are grouped into three categories based on power rating and package type: low-power equivalents (150–300 mW range), mid-power alternatives (310–375 mW range), and higher-power options (550 mW range). All substitute parts maintain the 36 V zener voltage specification and surface mount configuration required for direct functional replacement.

Engineering Selection Recommendations

Direct Replacement (Same Power Rating): EDZVFHT2R36B is the closest functional equivalent to MAZS360GML. Both parts share identical 36 V zener voltage, 150 mW power rating, and SOD-523 package configuration. EDZVFHT2R36B is manufactured by Rohm Semiconductor, holds active product status, and carries AEC-Q101 automotive qualification. The ±2.5% tolerance is tighter than the original ±3%, providing improved voltage regulation accuracy.

Higher Power Alternatives (SOD-523 Package): BZT585B36T-7 (Diodes Incorporated) and BZX585-B36,115 / BZX585-C36,115 (Nexperia) maintain the SOD-523 package footprint while offering increased power dissipation (300–350 mW). These parts are suitable for applications requiring enhanced thermal performance. BZX585-B36,115 and BZX585-C36,115 carry AEC-Q100 automotive qualification and active product status.

Higher Power Alternatives (SOD-323F Package): BZX84J-B36,115 and BZX84J-C36,115 (Nexperia) provide 550 mW power rating in the larger SOD-323F package. These parts feature AEC-Q101 automotive qualification and are recommended for designs with increased power dissipation requirements or where package size permits larger footprints.

Mid-Power Alternative (SOD-123F Package): BZT52H-C36,115 (Nexperia) offers 375 mW in the SOD-123F package with AEC-Q101 qualification. This part is suitable for applications requiring moderate power increase with a different package footprint.

All substitute parts maintain RoHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status, ensuring regulatory compatibility with the original MAZS360GML specification.

Frequently Asked Questions (FAQ)

Q: Can EDZVFHT2R36B directly replace MAZS360GML without PCB layout changes? A: Yes. EDZVFHT2R36B shares the same SOD-523 package and pinout as MAZS360GML. No PCB modifications are required for direct substitution.

Q: What is the primary reason to select a higher power-rated substitute? A: Higher power-rated zener diodes (300–550 mW) provide improved thermal margin in applications with sustained current flow or elevated ambient temperatures. Selection depends on actual circuit power dissipation requirements.

Q: Are all substitute parts automotive-qualified? A: All listed substitute parts carry either AEC-Q100 or AEC-Q101 automotive qualification. EDZVFHT2R36B, BZT52H-C36,115, BZX84J-B36,115, and BZX84J-C36,115 hold AEC-Q101 qualification. BZX585-B36,115, BZX585-C36,115, and PZU36B,115 hold AEC-Q100 qualification.

Q: What is the difference between ±2%, ±2.5%, ±3%, and ±5% tolerance ratings? A: Tolerance specifies the allowable deviation of the zener voltage from the nominal 36 V specification. Tighter tolerances (±2%, ±2.5%) provide more precise voltage regulation. The original MAZS360GML specifies ±3%. Substitute parts with ±2% or ±2.5% tolerance offer improved accuracy; ±5% tolerance parts are acceptable for less stringent applications.

Q: Can I use a SOD-323F package part in place of a SOD-523 package part? A: SOD-323F and SOD-523 packages have different physical dimensions and pinout configurations. PCB layout modifications are required. Verify footprint compatibility before substitution.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts maintain MSL 1 specification.

Q: Is BZT585B36T-7 a suitable substitute if my circuit requires higher power dissipation? A: Yes. BZT585B36T-7 provides 350 mW power rating compared to the original 150 mW, maintaining the SOD-523 package footprint. This part is active and suitable for applications requiring increased thermal capacity.

Q: What is the impedance (Zzt) parameter, and why does it vary among substitutes? A: Impedance (Zzt) represents the dynamic resistance of the zener diode at specified operating conditions. Lower impedance values (60–90 Ohms) indicate better voltage regulation stability. The original MAZS360GML specifies 250 Ohms; most substitutes offer lower impedance (60–90 Ohms), providing superior regulation performance.
