Product details
Overview
M3Z4V7C RRG from Taiwan Semiconductor is a 200 mW, 4.7 V ±5% tolerance Zener diode in SOD-323F package, designed for precision voltage regulation and reference in low-power DC/DC converters, lighting circuits, and adapter power supplies.
For engineers reviewing the M3Z4V7C RRG datasheet, M3Z4V7C RRG pinout, M3Z4V7C RRG application, or M3Z4V7C RRG equivalent, key selection criteria include zener voltage (4.4–5.0 V), dynamic impedance (70 Ω max at 5 mA), leakage current (2 µA max at 1 V), junction temperature range (−55 to +150 °C), and RoHS/halogen-free compliance.
Technical Context
The M3Z4V7C RRG operates as a single-die, surface-mount Zener diode with sharp reverse breakdown at nominal 4.7 V. Its 70 Ω maximum dynamic impedance at 5 mA test current ensures stable regulation under moderate load transients.
Designed for ambient temperatures up to +150 °C, it maintains specified leakage current ≤2 µA at 1 V reverse bias and supports pulse testing per 10 ms duration. The SOD-323F package enables high-density PCB layouts while meeting J-STD-020 Level 1 moisture sensitivity and JESD 201 Class 1A whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B4V7,115 (Nexperia) | Same 4.7 V nominal, ±5% tolerance, but 300 mW rating and SOD-323 package (not SOD-323F); 90 Ω ZZT max | Higher power handling allows higher current regulation; slightly larger footprint may affect layout density | Select if >200 mW dissipation is required; verify pad compatibility with SOD-323 vs. SOD-323F land pattern |
| MMBZ5225BS-7-F (Diodes Inc.) | 4.6–4.8 V range, ±5%, 225 mW, SOT-23 package; 15 Ω ZZT max - lower impedance but different form factor | Lower dynamic impedance improves regulation fidelity; SOT-23 requires different stencil and placement setup | Prefer where tighter regulation is critical and SOT-23 assembly infrastructure exists |
Compared with BZX384-B4V7,115 and MMBZ5225BS-7-F, the M3Z4V7C RRG offers optimized balance of low-profile SOD-323F packaging, industry-standard 200 mW rating, and 70 Ω impedance - making it ideal for cost-sensitive, space-constrained applications where exact 4.7 V reference stability is prioritized over ultra-low ZZT or extended power headroom.

FAQ
What is the nominal zener voltage and tolerance of M3Z4V7C RRG?
The M3Z4V7C RRG has a nominal zener voltage of 4.7 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 4.4 V and 5.0 V when tested at 5 mA. This specification is verified per the Taiwan Semiconductor datasheet Version B2008 and applies under standard conditions (TA = 25 °C). The M3Z4V7C RRG maintains this tolerance across its qualified operating temperature range.
What package type does M3Z4V7C RRG use, and what are its key mechanical features?
M3Z4V7C RRG uses the SOD-323F surface-mount package - measuring 1.7 × 1.25 × 0.9 mm with matte tin-plated leads and a visible cathode band. It meets UL 94 V-0 flammability, J-STD-020 Level 1 moisture sensitivity, and JESD 201 Class 1A whisker resistance. The M3Z4V7C RRG's lightweight 3.4 mg construction supports high-speed pick-and-place assembly without lead deformation.
What is the maximum dynamic impedance of M3Z4V7C RRG, and why does it matter in circuit design?
The M3Z4V7C RRG has a maximum dynamic impedance (ZZT) of 70 Ω at 5 mA test current. This value directly impacts regulation accuracy: lower ZZT means less output voltage shift under varying load currents. In practice, the M3Z4V7C RRG's 70 Ω rating ensures stable 4.7 V reference performance in feedback networks and low-noise biasing applications where tight voltage control is essential.
How does the leakage current specification of M3Z4V7C RRG affect low-power designs?
M3Z4V7C RRG specifies a maximum leakage current of 2 µA at 1 V reverse bias (VR). This ultra-low leakage minimizes parasitic current draw in battery-powered or energy-harvesting systems - for example, preserving runtime in always-on sensor nodes or backup power rails. The M3Z4V7C RRG's leakage remains within this limit across its full −55 to +150 °C operating range, ensuring consistent low-power behavior.
Is M3Z4V7C RRG compliant with environmental regulations such as RoHS and halogen-free standards?
Yes, M3Z4V7C RRG is RoHS compliant and halogen-free per IEC 61249-2-21. These certifications are confirmed in the official Taiwan Semiconductor datasheet (Version B2008) and verified through material declarations. The M3Z4V7C RRG contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and its molding compound and plating meet strict halogen content thresholds - supporting global market access and sustainable manufacturing requirements.
