概述

Description

MMBZ5245BLT1G is a fixed Zener diode from ON Semiconductor’s MMBZ series. It is a low-power (about 0.5 W) surface-mount Zener used for voltage regulation, clamping, and voltage references in small‑signal and power-supply circuits. The device comes in the MMBZ family package with the LT1G suffix indicating RoHS-compliant packaging (tape/rail). The “5245” in the part name denotes its nominal Zener voltage, but the exact value, tolerance, and current ratings are specified in the datasheet. Typical uses include stabilizing microcontroller rails, protecting inputs from overvoltage, and providing simple reference voltages in portable/compact designs. For precise electrical parameters (Vz, Iz, leakage, dynamic impedance, temperature range), consult the MMBZ5245BLT1G datasheet.
