Product Description

onsemi 1N4746ATR Zener Diode is a reliable general purpose semiconductor component engineered for voltage regulation and protection in electronic circuits. This diode features a nominal Zener voltage of 18 volts with a tight tolerance of ±5%, allowing stable voltage reference in various power supply and signal conditioning circuits.

The device supports a maximum power dissipation of 1 watt, enabling sustained operation under typical electrical loads without thermal failure. The two-pin DO-41 package facilitates through hole mounting, providing robust mechanical and electrical connections in printed circuit board assemblies.

Its maximum reverse leakage current is limited to 5 microamperes, ensuring minimal leakage when reverse biased. The maximum Zener impedance of 20 ohms contributes to smooth voltage stabilization at the rated current of 14 mA.

Designed for a wide ambient temperature range from -65°C to 200°C, the 1N4746ATR is suitable for demanding industrial, laboratory, and commercial electronics applications requiring reliable voltage references or transient voltage suppression.

Single diode configuration with two-pin DO-41 package ensures easy PCB integration. Nominal Zener voltage of 18 V with ±5% tolerance for precise regulation. 1 W power dissipation supports stable operation in low power circuits.

Wide operating temperature range from -65°C to 200°C for harsh environments. Low reverse leakage current and moderate Zener impedance for efficiency. Compact physical dimensions allow space-efficient circuit layouts. General purpose Zener diode suitable for voltage regulation and protection.

Applications include industrial electronics, power supply regulation, signal conditioning, and laboratory instrumentation where stable voltage references are critical.
