MMBZ18VALT1G是UMW友台半导体推出的一款双路单向瞬态抑制二极管(TVS),核心作用是快速抑制电子电路中的瞬态过压(如静电放电、浪涌脉冲),将电压钳位在安全范围,保护后级敏感元件(如MCU、传感器、接口芯片)免受损坏。该器件采用紧凑的SOT-23贴片封装,主打小尺寸、双路防护、低功耗,适配空间受限的小型化应用场景,是消费电子、工业微模块等领域的高性价比防护方案。
该器件的关键参数明确了其防护能力与工作边界,核心指标及实际意义如下:
MMBZ18VALT1G采用SOT-23贴片封装,尺寸紧凑(典型规格:2.9mm×1.6mm×1.1mm),适配自动化贴装生产线,同时满足小型电子设备的空间需求。
器件为双路集成设计,可同时为两路独立电路(如双路数据线、双路电源输入)提供防护,减少PCB上的器件数量,简化电路布局(无需使用两个单路TVS管),进一步降低设计成本与空间占用。
该器件符合IEC 61000-4-2静电放电防护标准,可应对±8kV(接触放电)、±15kV(空气放电)等常见静电冲击,同时具备对浪涌脉冲的抑制能力,可靠性覆盖工业级与消费级设备的防护要求。
其击穿电压一致性好(典型偏差±5%)、漏电流稳定,长期工作下防护性能无明显衰减,可有效降低设备的静电/浪涌故障率。
基于小封装、双路防护、低功耗的特点,MMBZ18VALT1G广泛应用于以下领域:
综上,MMBZ18VALT1G以紧凑封装、双路防护、低功耗为核心优势,是小型化电子设备过压防护的实用选择,可有效提升设备的抗干扰能力与可靠性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
