Product details
Overview
M3Z2V0C from Taiwan Semiconductor is a 200mW surface-mount Zener diode with a nominal zener voltage of 2.0V (±5% tolerance), designed for low-voltage stabilization and precision voltage reference in space-constrained DC/DC converters and lighting circuits. It features a SOD-323F package, 150°C maximum junction temperature, and 100Ω dynamic impedance at 5mA test current.
For engineers reviewing the M3Z2V0C datasheet, M3Z2V0C pinout, M3Z2V0C application, or M3Z2V0C equivalent, key selection criteria include its 2.0V zener voltage tolerance, 200mW power rating, SOD-323F thermal and mechanical footprint, and leakage current of ≤120µA at 1V reverse bias - all critical for low-power voltage regulation in portable and automotive auxiliary systems.
Technical Context
The M3Z2V0C operates as a single-die, cathode-banded Zener diode optimized for stable reverse-breakdown conduction at 2.0V. Its 100Ω dynamic impedance at IZ = 5mA and 600Ω at IZK = 1mA ensures predictable regulation under light and near-knee load conditions.
Rated for -55°C to +150°C junction temperature and moisture sensitivity level 1 (J-STD-020), it supports reflow-compatible assembly without baking. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 1A whisker resistance requirements.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 1.9–2.1 V at IZ = 5 mA; enables precise 2.0V reference with ±5% tolerance for low-voltage rail clamping |
| Power Dissipation (PD) | 200 mW; limits continuous current to ~100 mA at 2V, suitable for signal-level and biasing applications |
| Dynamic Impedance (ZZT) | 100 Ω at IZ = 5 mA; ensures minimal output voltage shift under small load variations |
| Leakage Current (IR) | ≤120 µA at VR = 1 V; maintains low quiescent loss in always-on reference paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V0,115 (Nexperia) | Same 2.0V ±5%, SOD-323 package, but 300mW rating and higher 150Ω ZZT | Higher power handling suits intermittent surge clamping; less stable at microamp bias currents | Select when transient energy absorption >200mW is required; verify thermal layout for sustained dissipation |
| MMBZ5221BS-7-F (Diodes Inc.) | 2.0V ±5%, SOT-23 package (larger footprint), 350mW rating, 110Ω ZZT | SOT-23 requires different pad layout; better thermal mass for pulsed loads but incompatible with dense SOD-323 layouts | Choose only if board redesign accommodates 2.9 × 1.3 mm footprint and higher assembly cost is acceptable |
Compared with BZX384-B2V0 and MMBZ5221BS-7-F, the M3Z2V0C offers optimal balance of size, leakage (≤120µA), and impedance (100Ω) for space-constrained, low-quiescent reference designs - especially where SOD-323F's MSL Level 1 and whisker resistance are mandatory.

FAQ
What is the exact zener voltage range and tolerance for M3Z2V0C?
The M3Z2V0C has a nominal zener voltage of 2.0V with a guaranteed range of 1.9V to 2.1V at IZ = 5 mA, corresponding to a ±5% tolerance per the official Taiwan Semiconductor datasheet revision B2008. This tolerance is tested and binned during production, and applies strictly under DC conditions with pulse testing per PW = 10ms.
Does M3Z2V0C support lead-free reflow soldering without moisture preconditioning?
Yes, the M3Z2V0C is rated MSL Level 1 per J-STD-020, meaning it can undergo standard Pb-free reflow (peak 260°C) without prior baking or dry-pack handling. Its SOD-323F molding compound and matte tin plating are fully qualified for IPC-J-STD-020-compliant assembly processes used in high-volume manufacturing.
What is the maximum reverse leakage current for M3Z2V0C, and at what voltage is it specified?
The M3Z2V0C exhibits a maximum reverse leakage current of 120 µA at VR = 1 V and TA = 25°C. This value is confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet and is critical for low-power reference applications where standby current must remain below 200 µA.
Can M3Z2V0C be used as a substitute for older through-hole 2.0V Zeners like 1N5221B?
No - the M3Z2V0C is not a drop-in replacement for 1N5221B due to fundamental differences in package (SOD-323F vs. DO-35), thermal resistance, and power derating curves. While both provide ~2.0V regulation, the M3Z2V0C's 200mW rating and surface-mount geometry require PCB redesign and thermal validation; it is intended for new compact designs, not legacy upgrades.
Is M3Z2V0C compliant with automotive AEC-Q101 qualification standards?
No - the M3Z2V0C is not AEC-Q101 qualified. Taiwan Semiconductor does not list AEC-Q101 test reports for this part. It is rated for industrial and commercial use with a -55°C to +150°C junction temperature range, but automotive-grade qualification requires additional stress testing and lot traceability not included in its current specification.
