SZMM3ZxT1G Automotive Zener Voltage Regulators

onsemi SZMM3ZxT1G Automotive Zener Voltage Regulators are compact, high-reliability devices designed for voltage regulation and protection in automotive electronic systems. Packaged in a space-saving SOD-323 format, these onsemi regulators offer Zener breakdown voltages ranging from 2.4V to 75V, making the devices versatile for a wide range of applications. SZMM3ZxT1G regulators are AEC-Q101 qualified, ensuring dependable performance under harsh automotive conditions, including high temperatures and electrical stress. A robust design and broad voltage range make these zener voltage regulators ideal for safeguarding sensitive components and maintaining stable operation in modern automotive environments. Typical uses include voltage clamping, surge protection, and reference voltage generation in systems such as engine control units (ECUs), infotainment electronics, sensors, and power management circuits. The onsemi SZMM3ZxT1G is also well-suited for applications such as cellular phones, handheld portables, and high-density PC boards.
