Taiwan Semiconductor Corporation M3Z15VC RRG

Overview

M3Z15VC from Taiwan Semiconductor is a surface-mount 15 V ±5% Zener diode in SOD-323F package, rated for 200 mW power dissipation and operating from –55°C to +150°C junction temperature; it provides stable voltage reference in low-power DC/DC converters, LED lighting drivers, and AC/DC adapter feedback loops.

For engineers reviewing the M3Z15VC datasheet, M3Z15VC pinout, M3Z15VC application, or M3Z15VC equivalent, key selection criteria include its 15.0 V nominal zener voltage (min 14.25 V, max 15.75 V), 30 Ω dynamic impedance at 5 mA test current, 0.1 µA leakage at 11 V reverse bias, SOD-323F footprint compatibility, and RoHS/halogen-free compliance for consumer and industrial PCB designs.

Technical Context

The M3Z15VC operates as a single-die, cathode-banded silicon Zener diode optimized for precision voltage regulation in low-current, space-constrained applications. Its breakdown behavior follows standard avalanche mechanism with pulse-tested zener voltage (PW = 10 ms) and exhibits low dynamic impedance (30 Ω) at I_Z = 5 mA.

Designed for surface-mount assembly per J-STD-002, it features matte tin-plated leads, JESD201 Class 1A whisker resistance, and moisture sensitivity level 1 (J-STD-020). Thermal performance is validated across –55°C to +150°C ambient and junction ranges, with power derating linear above 75°C.

FAQ

What is the nominal zener voltage and tolerance of the M3Z15VC?

The M3Z15VC has a nominal zener voltage of 15.0 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 14.25 V and 15.75 V when tested at 5 mA. This specification is verified per the manufacturer's electrical characteristics table and applies under standard test conditions (T_A = 25°C, pulse width = 10 ms). The M3Z15VC maintains this tolerance across its qualified operating temperature range.

What package type does the M3Z15VC use, and what are its key mechanical features?

The M3Z15VC uses the SOD-323F surface-mount package, measuring 1.7 × 1.25 × 0.9 mm, with matte tin-plated gull-wing leads compliant with J-STD-002 solderability standards. It features a cathode band for polarity identification, UL 94 V-0 flammability-rated molding compound, and JESD201 Class 1A whisker resistance. The M3Z15VC is rated moisture sensitivity level 1 per J-STD-020, eliminating pre-reflow baking requirements.

What is the maximum power dissipation and thermal rating of the M3Z15VC?

The M3Z15VC is rated for 200 mW power dissipation at 25°C ambient temperature, with linear derating above 75°C. Its junction temperature range is –55°C to +150°C, and storage temperature range matches this span. These ratings are confirmed in the Absolute Maximum Ratings table and supported by the Fig.7 power derating curve in the official datasheet. The M3Z15VC sustains full 200 mW operation only within the specified ambient limits.

How does the leakage current of the M3Z15VC compare at 11 V reverse bias?

At 11 V reverse bias and T_A = 25°C, the M3Z15VC exhibits a maximum leakage current of 0.1 µA, as specified in the Electrical Characteristics table. This low leakage supports high-impedance voltage divider networks used in precision feedback paths. The M3Z15VC maintains this value across its full operating temperature range, with typical leakage increasing to ~1 µA at 100°C per the Fig.6 leakage curve.

Is the M3Z15VC compliant with RoHS and halogen-free standards?

Yes, the M3Z15VC is RoHS compliant and halogen-free per IEC 61249-2-21. This compliance is explicitly stated in the Features section of the official datasheet and verified through material declarations. The M3Z15VC contains no brominated flame retardants, chlorine, fluorine, iodine, or bromine above threshold limits - making it suitable for export to EU, Japan, and other regulated markets where halogen-free content is mandatory.
