ONSEMI 1N4743A Zener Voltage Regulator The ONSEMI 1N4743A is a high-reliability zener diode specifically engineered for voltage stabilization applications. Its key features include a very sharp reverse characteristic, ensuring precise voltage regulation, and a low reverse current level, minimizing power consumption. The device is characterized by a Vz-tolerance of ±5%, indicating a consistent and predictable breakdown voltage. It is commonly used in power supplies, voltage regulators, and other circuits where a stable voltage is required. The 1N4743A is packaged in a standard glass case (JEDEC DO-41) and operates within a temperature range of -55°C to +150°C.
