SZMMSZ52xT1G Automotive Zener Voltage Regulators

onsemi SZMMSZ52xT1G Automotive Zener Voltage Regulators are robust, surface-mount devices designed to provide precise voltage regulation and overvoltage protection in automotive and industrial applications. Packaged in a compact SOD-123 format, these Zener diodes offer a wide breakdown voltage range from 2.4V to 110V, making the components suitable for a variety of circuit protection and voltage reference tasks. The onsemi SZMMSZ52xT1G regulators are qualified to AEC-Q101 standards, ensuring high reliability under harsh environmental conditions, including extended temperature ranges from -55°C to +150°C. With features such as low leakage current and sharp breakdown characteristics, the SZMMSZ52xT1G series is ideal for use in electronic control units (ECUs), sensor interfaces, infotainment systems, and battery management circuits, where stable and predictable voltage regulation is critical.
