Visão Geral

Description

MMBZ5230BLT1G is a 5.1 V Zener diode in the MMBZ family (SOT-23) from ON Semiconductor. It’s a unidirectional Zener rated for about 0.5 W, with a nominal Zener voltage of 5.1 V and tolerance around ±5% (B-series). The “L” indicates a lead-free RoHS-compliant part, and “T1G” denotes tape-and-reel packaging. Typical uses include simple voltage regulation, voltage references, and overvoltage or transient protection in low-current circuits. In operation, it is reverse-biased and clamps the voltage near 5.1 V with relatively low dynamic impedance within its specified current range.

Equivalent

MMBZ5230BLT1G is a 6.2 V, 0.5 W Zener diode in a SOT-23 package (MMBZ series). Common equivalents:
- Diodes Incorporated MMSZ5230BT1G
- Vishay BZX84C6V2
- Nexperia BZX84C6V2
(Voltage and package match; always verify lead configuration in datasheets.)
