SMBJ5.0A 产品概述
一、产品简介
SMBJ5.0A（品牌：GOODWORK/固得沃克）为单向瞬态电压抑制器（TVS/ESD），封装为SMB（DO-214AA）。专为抑制静电放电和浪涌电流设计，可在瞬态冲击下保护敏感电子元件和接口电路。
二、主要电气参数
- 反向工作电压 Vrwm：5V
- 击穿电压（典型）Vbr：6.4V
- 钳位电压 Vc（在指定Ipp下）：9.2V
- 峰值脉冲功率 Ppp（10/1000µs或常用10/1000µs请参照厂商数据）：600W
- 峰值脉冲电流 Ipp：65.2A
- 反向漏电流 Ir：800µA（在 Vrwm 条件下典型值）
- 极性：单向
- 工作结温范围 Tj：-55℃ ~ +150℃
三、关键特点
- 高能量吸收能力：600W 峰值脉冲功率配合 65.2A 峰值电流，能有效衰减大电流浪涌。
- 低钳位电压：典型 9.2V 钳位电压，可在保护电路同时降低对被保护器件的应力。
- 宽温度范围：-55℃～+150℃，适用于工业级环境。
- SMB 封装：便于自动贴装与波峰/回流焊接，适合 PCB 边缘和接口保护。
四、典型应用
- 电源线、数据总线、接口（USB、RS-485、CAN、Ethernet）防护
- 工业控制设备、通信基站、汽车电子辅助保护（非高可靠安全关键主电源）
- 消费类电子及测量仪器的输入端浪涌抑制
五、封装与热特性
SMB（DO-214AA）封装具备较好散热路径，推荐在 PCB 设计时靠近被保护线路布置热通道和充足铜箔面积，以利热量传导和提高寿命。
六、选型与使用建议
- 若系统工作电压接近 5V，SMBJ5.0A 为合适选择；若保护电压需求更低或更高，请参考相邻标称型号。
- 注意峰值脉冲波形（10/1000µs 或 8/20µs）对能量吸收能力的影响，按实际浪涌源选择。
- 对长期漏电流敏感的电路需评估 800µA 的影响，必要时选择漏电更低的型号。
七、存储与可靠性注意事项
- 避免潮湿环境，按厂家建议进行干燥箱存储与回流前烘干处理。
- 元器件应按 JEDEC/IPC 推荐的焊接曲线回流，避免过高峰值温度和超时焊接。
如需原厂数据手册（完整浪涌曲线、典型特性图与封装机械尺寸），建议联系 GOODWORK 获取详细规格书以完成最终设计验证。

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.
