MMBZ5V6A（SHIKUES）TVS稳压管 产品概述
一、产品简介
MMBZ5V6A 是 SHIKUES（时科）出品的一款单向 TVS（瞬态电压抑制）稳压管，采用双芯片结构，封装为 SOT-23。器件专为抑制瞬态过压、吸收浪涌脉冲能量而设计，适用于对电源线和信号线的过压保护，尤其适配 3V 级别系统和敏感电子模块。
二、主要参数
- 钳位电压（Vc，在指定击穿电流下）：8V
- 击穿电压（Vbr）：5.6V
- 反向截止电压（Vrwm / 工作电压）：3V
- 峰值脉冲功率（Ppp）：24W
- 峰值脉冲电流（Ipp）：3A（对应 Ppp/ Ipp = 8V 钳位）
- 反向漏电流（Ir）：≤5μA
- 极性：单向
- 工作温度范围：-55℃ ~ +150℃
- 封装：SOT-23（小型化，易于表贴）
三、工作原理与器件特性
该器件在正常工作电压（Vrwm=3V）下处于高阻断状态，漏电流小（Ir≤5μA），不会影响电路操作。当瞬态冲击使电压超过器件击穿点（约5.6V）时，器件进入导通并将能量吸收到钳位电压（约8V），从而保护下游元件免受过压损伤。双芯片结构降低动态电阻，提高瞬态吸收能力与热分散性能，有利于提升可靠性与重复冲击寿命。
四、典型应用场景
- 3.0～3.6V 电源总线瞬态保护（如 3.3V 单片机、模块电源）
- 通讯接口保护（UART、CAN、RS-485 等差分或单端总线）
- 汽车电子及工业控制中的浪涌抑制（工作温度宽，支持高温环境）
- USB、HDMI 等外部接口的输入端防护（需根据接口电平选型）
五、封装与布局建议
SOT-23 小型封装便于高密度 PCB 布局。建议：
- TVS 与被保护节点尽量靠近布置，走线短而粗，减小串联感抗和电阻。
- 为提高能量耗散，器件底部敷铜适当扩大散热区并通过数条过孔接地。
- 焊接按无铅工艺推荐的回流曲线进行，避免过热影响器件可靠性。
六、选型与使用注意事项
- Vrwm=3V 表明适合 3V 级别保护场景，若系统工作电压高于 Vrwm，器件将频繁触发不可用。
- Ppp 与 Ipp 为典型脉冲能力指标，实际浪涌能量应参考标准脉冲波形（如 10/1000μs 或 8/20μs）并留安全裕量。
- 需要更高能量承受能力时，可采用并联或选择更大功率规格器件，注意并联时需匹配特性避免一分流不均。
- 单向器件需正确极性连接：阳极接地（或电源负），阴极朝被保护电路，以确保正常工作。
MMBZ5V6A 以其小封装、低漏电、较高瞬态吸收能力和宽温度范围，适合对体积和可靠性有要求的工业、汽车及消费电子保护设计。购买或设计前，请结合实际脉冲波形、系统工作电压和热环境做最终验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
