M3Z43VC Zener Diode Equivalent & Substitute Parts

Part Overview

The M3Z43VC is an active surface mount Zener diode manufactured by Taiwan Semiconductor Corporation, rated at 43 V nominal with 200 mW power dissipation and ±5% tolerance. This component is designed for voltage regulation and protection applications in electronic circuits. The part is ROHS3 compliant and REACH unaffected, confirming its suitability for current manufacturing standards.

Substitute parts are identified based on matching electrical specifications and mechanical compatibility. Alternative packaging configurations may be required to accommodate different procurement channels or assembly processes while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M3Z43VC is determined by equivalence across the following critical parameters:

• Voltage - Zener (Nom): 43 V
• Tolerance: ±5%
• Power - Max: 200 mW
• Impedance (Max): 90 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 32 V
• Operating Temperature Range: -55°C to 150°C
• Package / Case: SC-90, SOD-323F
• Mounting Type: Surface Mount

Parts meeting these specifications are electrically and mechanically interchangeable. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect component performance and reflect only procurement and handling variations.

Parameter Comparison

Engineering Selection Recommendations

Both M3Z43VC and M3Z43VC RRG are active products from Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. Selection between these parts is based on packaging and procurement requirements rather than performance differences.

The M3Z43VC in Tape & Reel format is suitable for high-volume automated assembly operations. The M3Z43VC RRG in Cut Tape & Digi-Reel format accommodates lower-volume production runs and alternative handling systems.

Both variants maintain ROHS3 compliance and REACH unaffected status, confirming regulatory alignment for current manufacturing environments. The identical operating temperature range (-55°C to 150°C) and electrical parameters ensure direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can M3Z43VC and M3Z43VC RRG be used interchangeably in the same circuit?

A: Yes. Both parts are electrically identical with matching voltage, power, impedance, and temperature specifications. They differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel), which does not affect electrical performance.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging is optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel packaging accommodates lower-volume production and alternative handling equipment. The physical component remains identical.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both M3Z43VC and M3Z43VC RRG are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: What are the critical parameters for substitution?

A: Zener voltage (43 V), tolerance (±5%), maximum power (200 mW), impedance (90 Ohms maximum), reverse leakage current (100 nA @ 32 V), operating temperature range (-55°C to 150°C), and package type (SOD-323F) must all match for direct substitution.

Q: Can these parts be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures up to 150°C (TJ), suitable for applications requiring extended thermal performance within this range.

Q: Is there a difference in reverse leakage characteristics between the two parts?

A: No. Both parts specify identical reverse leakage current of 100 nA @ 32 V, ensuring equivalent performance in voltage regulation and protection circuits.
