1N4745ATR Description

Short technical summary and product information.

The 1N4745ATR is a Zener diode manufactured by On Semiconductor, designed for voltage regulation and reference applications. It features a nominal Zener voltage of 16V with a tolerance of ±5%, making it suitable for precise voltage clamping and stabilization.

 

With a power dissipation rating of 1W, this diode can handle moderate power levels in through-hole designs. The maximum impedance (Zzt) is 16Ω, and the reverse leakage current is 5µA at 12.2V, ensuring low standby power loss.

 

The device is housed in a DO-204AL (DO-41) axial-lead package, which is widely used for general-purpose through-hole mounting. It operates over a temperature range of -65°C to 200°C, providing robust performance in harsh environments.
