SMBJ5.0A 产品概述
一、产品简介
SMBJ5.0A 是东沃（DOWO）推出的一款单向瞬态电压抑制二极管（TVS），封装为 SMB（DO‑214AA）。器件以 5V 工作电压为针对目标，专为抑制瞬态过压、浪涌和静电放电（ESD）而设计，适用于各种 5V 电源总线与接口保护。
二、主要电气参数
- 极性：单向
- 反向工作电压 Vrwm：5V
- 击穿电压 VBR(min)：6.4V
- 钳位电压 VC：9.2V（在 IPP = 65.22A 条件下）
- 峰值脉冲电流 Ipp：65.22A
- 峰值脉冲功率 Ppp：600W（10/1000µs 波形）
- 反向漏电流 Ir：800µA（在 Vrwm 条件下）
- 类型：TVS（瞬态抑制二极管）
- 封装：SMB (DO‑214AA)
三、产品特点
- 针对 5V 体系优化的稳健钳位能力，能将高能脉冲限制在安全范围（VC≈9.2V@IPP）。
- 高峰值脉冲功率 600W（10/1000µs），可靠应对工业级浪涌与雷击诱导脉冲。
- SMB 表面贴装封装，便于自动贴装与规模化生产，良好热散特性。
- 单向结构适合直流电源与数据信号线的反向并联保护。
四、应用场景
- 5V 电源总线、USB/串口接口、外围接口保护
- 工业控制设备、通信设备、消费电子接口防护
- 电源模块端口与接地回路的瞬态抑制
五、选型与注意事项
- 适用于需要快速钳位但允许少量漏电流的场合；若系统对漏电流敏感（例如低功耗或ADC参考），请选择漏电流更低的型号或采取隔离措施。
- TVS 为瞬态保护元件，不应作为持续限压器长期承受能量；需保证浪涌发生后系统有足够恢复时间。
- 安装时应缩短引线/走线长度，采用良好地线布局以提升抑制效果并降低寄生感抗。
- 在高能脉冲环境下应考虑器件热耗散与PCB散热设计，必要时并联或在输入端增加串联阻抗以分担能量。
六、封装与可靠性
SMB（DO‑214AA）封装适配常见贴片工艺，便于回流焊和自动化生产。DOWO（东沃）品牌在元件一致性与批次可追溯性方面具备良好供应链支持，可满足批量应用需求。
如需完整的电气特性曲线、封装尺寸或在具体电路中的仿真建议，可提供更详尽的技术资料与应用参考图。

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.
