MMBZ5232BLT1G

MMBZ5232BLT1G is ON Semiconductor’s MMBZ family Zener diode in an SMD package. It provides a fixed Zener voltage for low‑power voltage regulation and over‑voltage protection in compact circuits (approx. 0.5 W rating). The “5232” designation encodes the nominal Zener voltage (the exact value is specified in the datasheet). The “LT1G” suffix indicates Tape‑and‑Reel packaging with lead‑free finish. Typical uses include reference generation, voltage clamping in regulator circuits, and protection against transients. It is operated in reverse bias with a current limited by a resistor and must stay within the recommended IZ and thermal limits. For exact voltage, current, tolerance, and thermal characteristics, consult the ON Semiconductor MMBZ5232BLT1G datasheet.
