Key Parameters

Substitute Part Grouping Explanation

Substitution of the M3Z15VC is determined by the following critical parameters:

Electrical Matching Criteria:

• Voltage - Zener (Nominal): 15 V
• Power - Maximum: 200 mW
• Impedance (Maximum): 30 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 11 V
• Operating Temperature Range: -55°C to 150°C

Mechanical Compatibility:

• Package / Case: SC-90, SOD-323F
• Mounting Type: Surface Mount

Tolerance Consideration: The M3Z15VC specifies ±5% tolerance. Substitute parts with ±2% tolerance (tighter tolerance) are electrically compatible and provide improved performance margin. Substitute parts with ±5% tolerance provide direct equivalence.

All identified substitute parts match the electrical specifications and package requirements of the M3Z15VC. Differences in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer): M3Z15VC RRG is manufactured by Taiwan Semiconductor Corporation and provides identical electrical specifications and package compatibility. This part differs only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Selection between M3Z15VC and M3Z15VC RRG is determined by supply chain requirements and packaging handling preferences.

Cross-Manufacturer Equivalents (Panjit International Inc.): The BZT52 series parts from Panjit International Inc. provide full electrical and mechanical compatibility. All BZT52 variants listed are ROHS3 compliant and REACH unaffected, matching the compliance profile of the M3Z15VC.

Tolerance Variants:

• BZT52-B15S-AU_R1_000A1 and BZT52-B15S_R1_00001 specify ±2% tolerance, providing tighter voltage regulation compared to the M3Z15VC ±5% specification.
• BZT52-C15S-AU_R1_000A1 and BZT52-C15S_R1_00001 specify ±5% tolerance, matching the M3Z15VC tolerance specification.

Automotive Grade Consideration: BZT52-B15S-AU_R1_000A1 and BZT52-C15S-AU_R1_000A1 carry automotive grade designation with AEC-Q101 qualification. These parts are suitable for applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can BZT52 series parts directly replace M3Z15VC in existing designs?

A: Yes. All BZT52 series parts listed match the M3Z15VC in voltage rating (15 V), power dissipation (200 mW), impedance (30 Ohms), reverse leakage current (100 nA @ 11 V), operating temperature range (-55°C to 150°C), and package type (SOD-323F). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between ±2% and ±5% tolerance variants?

A: Tolerance specifies the allowable deviation of the Zener voltage from the nominal 15 V rating. ±2% tolerance (BZT52-B series) restricts voltage variation to 14.7 V to 15.3 V, while ±5% tolerance (M3Z15VC and BZT52-C series) allows 14.25 V to 15.75 V. Applications requiring tighter voltage regulation benefit from ±2% tolerance parts. Applications with broader voltage acceptance use ±5% tolerance parts.

Q: Are packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) significant?

A: Packaging format affects supply chain logistics and handling but does not impact electrical or mechanical performance. Tape & Reel (TR) format is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® format provides flexibility for lower-volume or mixed-component orders. Selection is based on procurement and assembly process requirements.

Q: What does AEC-Q101 qualification indicate?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts carrying this qualification (BZT52-B15S-AU_R1_000A1 and BZT52-C15S-AU_R1_000A1) have undergone additional reliability testing and are approved for automotive applications. Non-automotive-qualified parts (M3Z15VC and standard BZT52 variants) are suitable for consumer and industrial applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed, including M3Z15VC, M3Z15VC RRG, and all BZT52 variants, are ROHS3 compliant and REACH unaffected. Compliance status is consistent across all equivalent and substitute parts.

Q: What inventory levels are available for each part?

A: Inventory availability varies by part number and supplier. M3Z15VC has 961 units in stock. M3Z15VC RRG has 4033 units. BZT52-B15S_R1_00001 has the highest inventory at 28303 units. Inventory levels should be confirmed with the supplier for procurement planning.
