SZMM3Z2V7T1G

SZMM3Z2V7T1G Description

The SZMM3Z2V7T1G from onsemi is a high-performance 2.7V Zener diode designed for precision voltage regulation and protection in automotive and industrial applications. Packaged in a compact SOD-323 surface-mount form factor, this diode delivers a 300 mW power dissipation with a tight ±5% tolerance on its nominal Zener voltage (Vz). It features a low forward voltage (Vf) of 900 mV @ 10 mA and a minimal reverse leakage current of 20 µA @ 1 V, ensuring efficient operation in low-power circuits. Compliant with ROHS3 and REACH standards, it meets stringent automotive-grade (AEC-Q101 qualified) requirements, making it ideal for harsh environments.

SZMM3Z2V7T1G Features

• Automotive-Grade Reliability: Qualified for AEC-Q101, ensuring robustness in temperature extremes and vibration-prone environments.
• Low Impedance: 100 Ω maximum Zzt ensures stable voltage clamping under dynamic load conditions.
• Precision Voltage Regulation: ±5% tolerance on 2.7V Zener voltage for consistent performance.
• Compact & Efficient: SOD-323 package (1.7mm x 1.25mm) saves board space while offering 300 mW power handling.
• Low Leakage: 20 µA @ 1 V reverse current minimizes power loss in standby modes.
• Wide Compliance: ROHS3, REACH Unaffected, and EAR99 classified for global supply chain flexibility.

SZMM3Z2V7T1G Applications

• Voltage Clamping: Protects sensitive ICs (e.g., MCUs, sensors) from transient spikes in automotive ECUs (Engine Control Units) and infotainment systems.
• Voltage Reference: Provides stable biasing for ADCs, DACs, and power management ICs in industrial control systems.
• Power Supply Regulation: Used in LDO bypass circuits and low-current voltage regulators for portable electronics.
• ESD Protection: Safeguards USB ports, HDMI interfaces, and CAN bus lines against electrostatic discharge.
