Product details
Overview
M3Z56VC RRG from Taiwan Semiconductor is a surface-mount 56 V ±5% tolerance Zener diode in SOD-323F package, rated for 200 mW power dissipation and operating across –55°C to +150°C junction temperature range; used for precision voltage reference and low-power stabilization in DC/DC converters and lighting circuits.
For engineers reviewing the M3Z56VC RRG datasheet, M3Z56VC RRG pinout, M3Z56VC RRG application, or M3Z56VC RRG equivalent, key selection criteria include zener voltage tolerance (±5%), dynamic impedance (135 Ω at 2.5 mA), leakage current (0.1 µA at 42 V), and moisture sensitivity level (MSL 1), all critical for stable biasing and compact board-level regulation.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 56 V reference with tight 5% tolerance (53.2–58.8 V). Its 200 mW power rating and 150°C max junction temperature support reliable operation in thermally constrained SMT designs.
Designed for single-die configuration in SOD-323F, it features matte tin-plated leads compliant with J-STD-002 solderability, polarity indicated by cathode band, and meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 53.2–58.8 V (±5% tolerance at IZ = 2.5 mA; enables precise voltage clamping in 56 V rail references) |
| Power Dissipation (PD) | 200 mW (limits continuous current to ~3.6 mA at 56 V; suitable for low-power bias and sensing) |
| Dynamic Impedance (ZZT) | 135 Ω (measured at IZ = 2.5 mA; determines regulation stiffness under load variation) |
| Leakage Current (IR) | 0.1 µA at 42 V (ensures minimal error current in high-impedance reference nodes) |
| Junction Temperature Range | –55°C to +150°C (supports operation in automotive under-hood and industrial ambient environments) |
| Package | SOD-323F (2-pin, 1.7 × 1.25 × 0.9 mm; compatible with standard 0805 reflow profiles and automated placement) |
Pinout & Package
SOD-323F is a two-terminal surface-mount package with cathode indicated by a band on the body; terminals are anode and cathode, with no internal connections beyond the single Zener junction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node | Connected to circuit common when used in reverse-biased Zener configuration |
| Cathode | Reverse breakdown terminal / Output reference node | Provides stable 56 V output relative to anode; marked by visible band on package |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Ensures predictable clamping within 2.8 V window at 56 V, reducing need for post-layout trimming |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking, simplifying manufacturing logistics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B56,115 (Nexperia) | Same 56 V ±5%, SOD-323 package, but 300 mW rating and higher leakage (0.5 µA @ 42 V) | Higher power handling supports transient surges; higher leakage may affect ultra-low-power references | Prefer for surge-prone adapter inputs where margin matters more than standby current |
| MMBZ5255B-7-F (Diodes Inc.) | 56 V ±5%, SOT-23 package (larger footprint), 350 mW rating, 100 Ω ZZT at 20 mA | Requires PCB layout change; lower impedance benefits dynamic regulation but increases quiescent current | Choose when tighter dynamic regulation is needed and SOT-23 placement is acceptable |
Compared with M3Z56VC RRG, the BZX384-B56 offers higher surge capability at the cost of leakage, while MMBZ5255B-7-F delivers lower impedance but demands larger board area - both require evaluation against thermal, space, and leakage constraints in final design.

FAQ
What is the zener voltage tolerance of M3Z56VC RRG?
The M3Z56VC RRG has a zener voltage tolerance of ±5%, meaning its nominal 56 V breakdown occurs between 53.2 V and 58.8 V when tested at 2.5 mA. This tolerance is confirmed in the Electrical Specifications table of the official Taiwan Semiconductor datasheet (Version B2008) and applies directly to the M3Z56VC RRG marking code "56".
What package type does M3Z56VC RRG use?
M3Z56VC RRG uses the SOD-323F surface-mount package - a 2-pin, gull-wing leaded outline measuring 1.7 × 1.25 × 0.9 mm, with matte tin-plated leads and cathode polarity indicated by a band. This is explicitly stated in the Mechanical Data and Ordering Information sections of the Taiwan Semiconductor datasheet.
What is the maximum power dissipation rating for M3Z56VC RRG?
M3Z56VC RRG is rated for 200 mW maximum power dissipation at 25°C ambient, derating linearly above 25°C per the Power Dissipation curve in the datasheet. At 100°C ambient, usable power drops to approximately 100 mW - a critical constraint for thermal design in enclosed lighting or adapter modules.
Is M3Z56VC RRG RoHS and halogen-free compliant?
Yes, M3Z56VC RRG is RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the Features section of the Taiwan Semiconductor datasheet. The molding compound also meets UL 94 V-0 flammability rating, supporting safety certification in end equipment.
What is the leakage current specification for M3Z56VC RRG?
M3Z56VC RRG specifies a maximum leakage current of 0.1 µA at 42 V (75% of nominal VZ), measured at 25°C. This value is listed in the Electrical Specifications table and reflects its suitability for high-impedance reference nodes where leakage-induced error must be minimized.
