MAZS1600ML Zener Diode 16V 150mW Equivalent & Substitute Parts

Part Overview

The MAZS1600ML is a surface mount Zener diode manufactured by Panasonic Electronic Components, rated for 16 V nominal Zener voltage with 150 mW maximum power dissipation. This device is packaged in SC-79/SOD-523 (SSMini2-F1) configuration and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts must maintain the core electrical specifications: 16 V Zener voltage, surface mount technology, and SOD-523 package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAZS1600ML is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage - Zener (Nom): Must equal 16 V
• Mounting Type: Must be Surface Mount
• Package / Case: Must be SC-79 or SOD-523 compatible
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

Secondary Compatibility Factors:

• Power - Max: Substitute parts may exceed the original 150 mW rating (higher power capability is acceptable for drop-in replacement)
• Impedance (Max): Substitute parts may have lower impedance values (improved performance characteristic)
• Tolerance: Substitute parts may have tighter tolerance (±2% acceptable for ±3% original)
• Reverse Leakage Current: Substitute parts must not exceed specified leakage at rated voltage

All four substitute parts meet the primary substitution criteria. Differences in power rating, impedance, and tolerance represent enhanced or equivalent electrical performance suitable for direct replacement in the MAZS1600ML application.

Engineering Selection Recommendations

BZT585B16T-7 (Diodes Incorporated) This substitute offers 350 mW power rating with ±2% tolerance and 40 Ohms impedance. Product status is active with RoHS3 compliance and REACH unaffected designation. The increased power capability provides design margin for the original 150 mW application. Packaging is Tape & Reel (TR), suitable for automated assembly.

BZX585-B16,115 (Nexperia USA Inc.) This substitute provides 300 mW power rating with ±2% tolerance and 40 Ohms impedance. Product status is active with AEC-Q101 automotive qualification and RoHS3 compliance. Operating temperature range is -65°C to 150°C. Packaging is Cut Tape (CT) & Digi-Reel®. Automotive grade qualification supports applications requiring automotive-level reliability.

BZX585-C16,115 (NXP USA Inc.) This substitute delivers 300 mW power rating with ±5% tolerance and 40 Ohms impedance. Product status is active with RoHS3 compliance and REACH unaffected status. Operating temperature range is -65°C to 150°C. The ±5% tolerance is wider than the original ±3%, suitable for applications with relaxed tolerance requirements.

BZX84J-B16,115 (NXP Semiconductors) This substitute offers the highest power rating at 550 mW with ±2% tolerance and 20 Ohms impedance (lowest impedance of all substitutes). Product status is active with AEC-Q101 automotive qualification. Package is SOD-323F (SC-90), which differs from the original SOD-523. This substitute requires PCB layout modification due to different package footprint.

Frequently Asked Questions (FAQ)

Q: Can BZX84J-B16,115 be used as a direct replacement for MAZS1600ML?

A: BZX84J-B16,115 maintains the 16 V Zener voltage specification but uses SOD-323F package (SC-90) instead of SOD-523 (SC-79). This requires PCB footprint modification. The electrical specifications are compatible, but physical placement differs. Use only if PCB redesign is feasible.

Q: What is the difference between the three SOD-523 packaged substitutes?

A: BZT585B16T-7, BZX585-B16,115, and BZX585-C16,115 all use SOD-523 packaging and are pin-compatible. Primary differences are power rating (350 mW, 300 mW, 300 mW respectively), tolerance (±2%, ±2%, ±5%), and certifications. BZX585-B16,115 includes automotive qualification; BZX585-C16,115 has wider tolerance.

Q: Is the higher power rating of substitute parts a concern?

A: No. Higher power rating (350 mW or 300 mW versus 150 mW) indicates improved thermal capability and is acceptable for drop-in replacement. The device will not operate at higher power unless the circuit demands it. This provides design margin and reliability improvement.

Q: Which substitute is recommended for automotive applications?

A: BZX585-B16,115 and BZX84J-B16,115 both carry AEC-Q101 automotive qualification. BZX585-B16,115 maintains SOD-523 package compatibility; BZX84J-B16,115 requires package change to SOD-323F.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All recommended substitutes maintain MSL 1 classification, ensuring compatibility with standard manufacturing processes.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences (±2% versus ±3% versus ±5%) affect Zener voltage accuracy. Tighter tolerance (±2%) provides better voltage regulation. Wider tolerance (±5%) is acceptable for applications with relaxed voltage regulation requirements. Verify circuit tolerance requirements before selection.

Q: Are all substitutes RoHS3 compliant?

A: BZT585B16T-7, BZX585-B16,115, and BZX585-C16,115 are explicitly RoHS3 compliant. BZX84J-B16,115 RoHS status is not specified in provided data. Verify RoHS compliance requirements for your application before final selection.
