1N4758A Description

Short technical summary and product information.

The 1N4758A is a 56V Zener diode from On Semiconductor, designed for voltage regulation and reference applications. With a nominal Zener voltage of 56V and a tolerance of ±5%, it provides a stable reference voltage. The diode can dissipate up to 1W of power, making it suitable for moderate power applications. It features a maximum impedance of 110Ω at the Zener test current. The reverse leakage current is 5µA at 42.6V reverse voltage. The device operates over a wide temperature range from -65°C to 200°C. The 1N4758A is housed in a DO-204AL/DO-41 axial-lead package, suitable for through-hole mounting. This part is RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited).
