MMBZ27VALT1G

Overview

The MMBZ27VALT1G is a dual monolithic silicon Zener transient voltage suppressor in an SOT-23 package. It features a common anode configuration with two unidirectional channels. Key electrical parameters include a maximum working peak reverse voltage (VRWM) of 22 V, a breakdown voltage (VBR) range of 25.65 V to 28.35 V at a test current of 1 mA, and a maximum clamping voltage (VC) of 40 V at a peak pulse current (IPP) of 1 A. The device handles a peak power dissipation of 40 W for a 1.0 ms pulse and has a maximum reverse leakage current of 50 nA at VRWM.

Feature Summary

Dual junction common anode design protects two separate lines using one package
SOT-23 package allows flexible configurations for board space optimization
ESD protection rated at IEC61000-4-2 Level 4, ±30 kV contact discharge

Applications

Computer interface protection
Microprocessor I/O protection
Keyboard terminal protection

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The standard T1 suffix indicates availability in an 8 mm tape and reel format containing 3,000 units per reel. Confirm RoHS compliance and Pb-free status requirements prior to procurement to ensure alignment with manufacturing standards.

Selection Notes

Select this component for applications requiring transient overvoltage protection on multiple lines within a compact footprint. Ensure the operating voltage does not exceed the 22 V working peak reverse voltage. Verify that the expected ESD events fall within the specified clamping voltage limits to protect downstream sensitive circuitry effectively.

Part Context

This part belongs to the MMBZxxxALT1G series of Zener diodes designed for transient voltage suppression. The series offers a standard Zener breakdown voltage range from 5.6 V to 47 V. These devices are intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, and medical equipment.
