The 1N4738A is a single Zener diode from On Semiconductor designed for voltage regulation applications. It provides a nominal Zener voltage of 8.2V with a tolerance of ±5%, ensuring precise voltage clamping. The device is rated for a power dissipation of 1W, making it suitable for low to moderate power regulation tasks in a variety of circuits. The Zener impedance (Zzt) is 4.5Ω, contributing to stable voltage regulation under varying current conditions.
This Zener diode is packaged in a DO-204AL (DO-41) axial leaded package, which supports through-hole mounting on printed circuit boards. It offers a wide operating temperature range from -65°C to 200°C, enabling reliable performance in extreme environments. The reverse leakage current is specified at 10µA at 6V, indicating low leakage under reverse bias conditions.
Typical applications include voltage clamping, overvoltage protection, and reference voltage generation in power supplies and analog circuits. The DO-41 package provides robust mechanical strength and ease of handling in both prototyping and production environments. The 1N4738A is a standard part in the popular 1N47xxA Zener series, offering a well-documented and widely available solution for voltage regulation needs.
