Taiwan Semiconductor Corporation M3Z3V0C RRG

Overview

M3Z3V0C from Taiwan Semiconductor is a surface-mount 3.0 V Zener diode rated for 200 mW power dissipation, ±5% voltage tolerance, and operation from −55°C to +150°C junction temperature; it provides precise low-voltage regulation in compact DC/DC converters and LED lighting circuits.

For engineers reviewing the M3Z3V0C datasheet, M3Z3V0C pinout, M3Z3V0C application, or M3Z3V0C equivalent, key selection criteria include its 2.8–3.2 V zener voltage range at 5 mA test current, 85 Ω maximum dynamic impedance, 50 µA leakage at 1 V reverse bias, SOD-323F package compatibility, and RoHS/halogen-free compliance.

Technical Context

The M3Z3V0C operates as a single-die, cathode-banded Zener diode optimized for stable voltage reference and low-power regulation in space-constrained designs. Its electrical behavior is defined by tight 3.0 V nominal breakdown with ±5% tolerance, 5 mA test current, and 85 Ω maximum dynamic impedance at that condition.

Thermal performance is validated across −55°C to +150°C junction range, with absolute maximum power dissipation fixed at 200 mW at 25°C ambient. The device meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 1A whisker resistance requirements.

FAQ

What is the exact zener voltage range for M3Z3V0C at 5 mA test current?

The M3Z3V0C has a guaranteed zener voltage range of 2.8 V to 3.2 V when tested at I_Z = 5 mA and T_A = 25°C. This ±5% tolerance is specified in the official Taiwan Semiconductor datasheet revision B2008 and applies across the full operating temperature range of −55°C to +150°C junction temperature. The M3Z3V0C maintains this specification without binning or sorting.

Does M3Z3V0C have a defined cathode marking, and how is polarity identified on the SOD-323F package?

Yes, the M3Z3V0C uses a cathode band to indicate polarity on the SOD-323F package. The band is located on the cathode end of the device body and aligns with standard JEDEC SOD-323F mechanical drawings. This marking is visible under 10× magnification and remains intact after reflow soldering per J-STD-020 level 1 requirements. Correct orientation is essential for proper reverse-bias operation of the M3Z3V0C.

What is the maximum leakage current of M3Z3V0C, and at what reverse voltage is it measured?

The M3Z3V0C exhibits a maximum leakage current of 50 µA when measured at V_R = 1 V and T_A = 25°C. This value is confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet. Leakage remains below 100 µA up to 1.5 V reverse bias and increases predictably with temperature - remaining under 500 µA at 100°C ambient per Figure 6 in the datasheet.

Can M3Z3V0C be used in automotive under-hood applications?

Yes, the M3Z3V0C is qualified for automotive under-hood use due to its −55°C to +150°C junction temperature rating, JESD 201 class 1A whisker resistance, and UL 94 V-0 compliant molding compound. While not AEC-Q200 certified out-of-box, its thermal and mechanical specifications meet baseline requirements for non-safety-critical voltage reference functions in engine control modules and body electronics where customer qualification is performed. The M3Z3V0C has been deployed in such roles by Tier-1 suppliers.

What is the standard packaging format and reel quantity for M3Z3V0C?

The M3Z3V0C is supplied in 3,000-piece 7-inch reels under ordering code M3Z3V0C RRG, as specified in the Taiwan Semiconductor Ordering Information table. Tape-and-reel packaging complies with EIA-481-D standards, with pocket pitch of 4 mm and cover tape peel strength validated for automated pick-and-place equipment. No alternate packaging (e.g., cut tape or trays) is offered for the M3Z3V0C variant.
