MM5Z11VT1G

MM5Z11VT1G Description

The MM5Z11VT1G from onsemi is a surface-mount Zener diode designed for precision voltage regulation and protection in compact electronic circuits. With a nominal Zener voltage (Vz) of 11V (±5.5% tolerance), it ensures stable performance in low-power applications. The diode features a 500 mW power dissipation rating and a low reverse leakage current of 100 nA at 8V, making it energy-efficient. Packaged in a SOD-523 (SC-79) form factor, it is ideal for space-constrained designs. The device is RoHS-compliant and REACH-unaffected, meeting environmental standards.

MM5Z11VT1G Features

• Low Forward Voltage: 900 mV at 10 mA minimizes power loss.
• High Stability: 20 Ohms maximum impedance (Zzt) ensures consistent performance under load.
• Compact & Reliable: SOD-523 package with MSL 1 (unlimited) moisture sensitivity, suitable for automated assembly.
• Wide Operating Range: Optimized for voltage clamping, regulation, and transient suppression in low-current circuits.
• Obsolete Status: While discontinued, it remains a robust choice for legacy designs or specific BOM requirements.

MM5Z11VT1G Applications

• Voltage Regulation: Precision reference in portable electronics, sensors, and IoT devices.
• Circuit Protection: ESD/transient suppression in communication interfaces (USB, HDMI) and microcontroller I/O lines.
• Power Management: Auxiliary voltage stabilization in battery-powered systems or low-voltage DC/DC converters.
• Automotive & Industrial: Secondary protection in CAN bus, infotainment systems, and control modules (where 11V clamping is critical).

Conclusion of MM5Z11VT1G

The MM5Z11VT1G offers a balance of compact size, low leakage, and reliable voltage regulation, making it a versatile choice for designers needing 11V Zener functionality in miniaturized applications. While marked obsolete, its low impedance and tight tolerance provide advantages over generic alternatives. Ideal for legacy upgrades or niche designs requiring proven performance in a tiny footprint.

(Note: Verify replacement options for new designs due to obsolete status.)
