Taiwan Semiconductor Corporation M3Z6V2C RRG

Overview

M3Z6V2C from Taiwan Semiconductor is a surface-mount Zener diode with a nominal zener voltage of 6.2 V, ±5% tolerance, 200 mW power rating, and 10 Ω dynamic impedance at 5 mA test current; it serves as a precision voltage reference or low-power voltage stabilizer in DC/DC converters and lighting circuits.

For engineers reviewing the M3Z6V2C datasheet, M3Z6V2C pinout, M3Z6V2C application, or M3Z6V2C equivalent, key selection criteria include zener voltage accuracy (5.89–6.51 V), low dynamic impedance (10 Ω @ 5 mA), SOD-323F package compatibility, and leakage current ≤1 µA at 3 V reverse bias.

Technical Context

The M3Z6V2C operates as a single-die, cathode-banded Zener diode optimized for stable voltage regulation in low-current, space-constrained applications. Its design supports operation across –55°C to +150°C junction temperature range and meets J-STD-020 moisture sensitivity level 1.

Electrical behavior is defined by tight zener voltage tolerance (±5%), low dynamic impedance (10 Ω), and controlled leakage (≤1 µA @ VR = 3 V). It uses matte tin-plated leads compliant with J-STD-002 solderability and passes JESD 201 Class 1A whisker testing.

FAQ

What is the exact zener voltage range for M3Z6V2C at 25°C?

The M3Z6V2C has a guaranteed zener voltage range of 5.89 V to 6.51 V at test current I_Z = 5 mA and ambient temperature 25°C. This ±5% tolerance is specified per the official Taiwan Semiconductor datasheet revision B2008 and applies to every unit shipped. The M3Z6V2C achieves this tight regulation using process-controlled silicon doping and laser-trimmed junction characteristics.

What is the maximum power dissipation of M3Z6V2C and how does it affect thermal design?

The M3Z6V2C has an absolute maximum power dissipation of 200 mW at 25°C ambient. Derating is required above 25°C - typically linear to zero at 150°C junction temperature. In practice, this means PCB copper area and airflow must limit junction temperature rise to ensure long-term reliability. The M3Z6V2C's SOD-323F package has low thermal resistance, enabling use in compact layouts without forced cooling.

Does M3Z6V2C meet RoHS and halogen-free compliance standards?

Yes, the M3Z6V2C is fully RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor certifies that all materials, plating (matte tin), molding compound, and internal die attach meet these environmental specifications. This compliance is verified through third-party material declarations and is documented in the M3Z6V2C product change notices and substance data sheets.

What is the leakage current specification for M3Z6V2C and at what reverse voltage is it measured?

The M3Z6V2C exhibits a maximum leakage current of 1 µA when reverse biased at 3 V (V_R = 3 V), per the official electrical specifications table. This low leakage supports energy-efficient designs, especially in battery-backed circuits or high-impedance voltage dividers. The value is measured at 25°C and remains ≤10 µA up to 150°C junction temperature.

Is M3Z6V2C suitable for use in automotive applications?

The M3Z6V2C is qualified for operation across –55°C to +150°C junction temperature and meets JESD 201 Class 1A whisker resistance, making it technically suitable for under-hood automotive modules. However, Taiwan Semiconductor explicitly states these devices are "not designed for use in medical, life-saving, or life-sustaining applications" - users must perform full AEC-Q101 qualification testing if deploying the M3Z6V2C in automotive safety-critical systems.
