Taiwan Semiconductor Corporation M3Z5V1C RRG

Overview

M3Z5V1C from Taiwan Semiconductor is a surface-mount 5.1 V ±5% Zener diode in SOD-323F package, rated for 200 mW power dissipation and operating across –55°C to +150°C junction temperature range; it delivers stable voltage reference or low-voltage regulation in compact DC/DC converters and LED lighting drivers.

For engineers reviewing the M3Z5V1C datasheet, M3Z5V1C pinout, M3Z5V1C application, or M3Z5V1C equivalent, key selection criteria include its 5.1 V nominal zener voltage (4.8–5.4 V), 50 Ω dynamic impedance at 5 mA test current, 2 µA leakage at 1.5 V reverse bias, 150°C max junction temperature, and SOD-323F package compatibility with high-density PCB layouts.

Technical Context

The M3Z5V1C operates as a single-die, silicon planar Zener diode optimized for precision voltage clamping and reference functions in low-power analog and power management circuits. Its design targets stable reverse breakdown behavior under DC and low-frequency transient conditions, with specified zener impedance measured at 5 mA and leakage current validated at 1.5 V.

It features a cathode band polarity indicator, matte tin-plated solderable terminals compliant with J-STD-002, and meets JESD201 Class 1A whisker resistance and UL 94 V-0 flammability requirements - all within a 3.4 mg SOD-323F outline.

FAQ

What is the nominal zener voltage and tolerance of the M3Z5V1C?

The M3Z5V1C has a nominal zener voltage of 5.1 V with a tolerance of ±5%, meaning its actual breakdown voltage falls between 4.8 V and 5.4 V when tested at 5 mA. This specification is verified per the manufacturer's electrical characteristics table and applies under standard 25°C ambient conditions. The M3Z5V1C maintains this voltage range across its full operating temperature span, supporting stable reference performance in real-world designs.

What is the maximum power dissipation rating for the M3Z5V1C?

The M3Z5V1C is rated for 200 mW maximum power dissipation at 25°C ambient temperature. Derating is required above 25°C per the published power dissipation vs. ambient temperature curve, reaching zero dissipation at 150°C. This rating reflects the device's thermal limits in the SOD-323F package and must be observed to prevent junction overheating. The M3Z5V1C's 150°C maximum junction temperature supports reliable operation in thermally demanding environments.

Does the M3Z5V1C meet RoHS and halogen-free requirements?

Yes, the M3Z5V1C is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. These environmental qualifications are explicitly stated in the product documentation and verified through material declarations. The M3Z5V1C uses lead-free matte tin plating on its terminals and complies with J-STD-002 solderability standards. These attributes make the M3Z5V1C suitable for global commercial and industrial electronics manufacturing.

What is the leakage current specification for the M3Z5V1C at 1.5 V reverse bias?

The M3Z5V1C exhibits a maximum leakage current of 2 µA at 1.5 V reverse bias voltage, as specified in the electrical characteristics table. This value is measured at 25°C and represents worst-case off-state conduction, critical for low-power and battery-operated systems. The M3Z5V1C's low leakage contributes directly to reduced standby power loss and improved accuracy in high-impedance reference networks where even nanoamp-level currents affect performance.

What package type does the M3Z5V1C use, and what are its key mechanical features?

The M3Z5V1C uses the SOD-323F surface-mount package - measuring 1.7 mm × 1.25 mm × 0.9 mm with a 3.4 mg typical weight. Key mechanical features include UL 94 V-0 rated molding compound, JESD201 Class 1A whisker resistance, and cathode polarity indicated by a visible band. The M3Z5V1C's SOD-323F footprint enables high-density PCB layouts while maintaining compatibility with standard reflow profiles defined in J-STD-020.
