概述

Description

MMBZ5226BLT1G is a 0.5 W, unidirectional Zener diode from ON Semiconductor. It provides a fixed regulation/clamping voltage of about 3.9 V (nominal Vz) when reverse-biased. The “LT1G” suffix indicates Tape & Reel packaging (RoHS-compliant). Typical regulation uses IZ T ≈ 5 mA to establish Vz, with higher currents increasing dissipation. Common applications: simple voltage regulation, overvoltage protection on low-power rails, reference points, and transient suppression in compact circuits. It’s a two-terminal device; the cathode is the end with the band on the package.

Features

Here are the key features of MMBZ5226BLT1G:
- Unidirectional Zener diode in a small SOT-23 package (surface-mount)
- Zener voltage: 2.6 V (MMBZ5226B family)
- Power rating: up to 0.5 W (Ptot) with appropriate derating
- Tight voltage tolerance (typical ±5%)
- Low reverse leakage and good zener impedance for regulation
- Wide operating temperature range: -55°C to +125°C
- RoHS-compliant, lead-free (BLT1G packaging is tape-and-reel)
- Suitable for voltage regulation, reference, and overvoltage protection in compact circuits

Package

SOD-123 surface-mount package (lead-free).

Pinout

- Pin count: 3 pins (SOT-23 package)
- Function: Unidirectional Zener diode (voltage regulator/clamp). It provides a fixed reverse breakdown voltage for voltage regulation or protection. Two pins are the Zener’s anode and cathode; the third pin is not connected (NC).

Manufacturer

- Manufacturer: ON Semiconductor (ON Semi)
- What kind of company: An American multinational semiconductor manufacturer that designs and produces discrete devices, integrated circuits, and other semiconductor components for automotive, industrial, communications, and consumer electronics.

Application

MMBZ5226BLT1G is a fixed zener diode (SOT-23) used for low‑power regulation and protection. Typical applications:
- Shunt regulator for low-current supplies and simple reference voltages
- Precision voltage reference for comparators, ADCs, and sensors
- Over‑voltage/transient protection and voltage clamping on supply or signal lines
- Signal conditioning (clipping, level shifting, peak detection) in analog circuits
These cover general non‑regulatory and reference/protection roles in compact circuits.
