概述

Description

MMBZ5230BLT1G is a small-signal Zener diode from ON Semiconductor’s MMBZ family. It provides a fixed breakdown voltage for regulation or clamping in compact, low-power circuits. It is a RoHS-compliant, surface-mount device rated around 0.5 W, suitable for reference generation, overvoltage protection, and transient clamping in DC supplies and logic circuits. The “5230” code identifies the voltage variant within the MMBZ5230B family; the exact zener voltage (Vz), tolerance, and other parameters are specified in the datasheet for this variant. The LT1G suffix indicates the lead-free, tape-and-reel packaging. For precise Vz, Izt, Zzt, Ir, and Ptot values, consult the MMBZ5230BLT1G datasheet.

Features

- Type: Unidirectional Zener diode for voltage regulation and overvoltage protection
- Zener voltage: 3.0 V nominal (±5%)
- Power rating: 0.5 W (500 mW)
- Temperature range: -55°C to 125°C
- Packaging: Small SMD with Tape & Reel LT1G variant (robust, surface-mount)
- RoHS-compliant (and suitable for compact, high-density layouts)
- Applications: voltage reference/ regulator, clamping, transient suppression in compact circuits

Package

SOD-123FL surface-mount package (lead-free); the T1G suffix indicates Tape‑and‑Reel packaging.

Pinout

- Pin count: 2 terminals (anode and cathode).
- Function: Zener diode with a nominal 3.0 V breakdown, used for voltage regulation/clamping in low-power circuits (SOD-123 package, RoHS T1G).

Manufacturer

- Manufacturer: ON Semiconductor (ON Semiconductor Corporation).
- What kind of company: A global American semiconductor manufacturer that designs and sells integrated circuits, discrete devices, and power-management solutions for automotive, industrial, communications, and consumer electronics.

Application

MMBZ5230BLT1G is a 3.0 V Zener diode used for:
- Shunt voltage regulation in low‑power circuits
- Precision reference for ADC/DAC and comparators
- Overvoltage protection by clamping inputs/rails
- Signal clipping and transient suppression on interfaces and sensors
- Basic ESD/surge protection in consumer electronics where a fixed reference is suitable
