SMBJ14CA/TR13 产品概述
一、产品简介
SMBJ14CA/TR13 为台湾 Brightking(君耀) 出品的双向瞬态电压抑制器（TVS），采用SMB（DO‑214AA）封装，专为保护敏感电子电路免受瞬态过压和电涌冲击而设计。器件在工业级温度范围内可靠工作，适合DC/AC线路和数据信号的过压保护应用。
二、主要技术参数
- 钳位电压（Vc）：23.2 V（典型值）
- 额定反向工作电压 Vrwm：14 V
- 击穿电压（Vbr）：15.6 V
- 峰值脉冲功率 Ppp：600 W（脉冲规范按厂商数据表）
- 峰值脉冲电流 Ipp：25.9 A
- 反向电流 Ir：1 μA（在 Vrwm 下）
- 极性：双向（Bi‑directional）
- 工作温度：-65 ℃ ～ +150 ℃
- 封装：SMB (DO‑214AA)
以上参数为器件典型/额定值，具体使用时请参考完整数据手册。
三、主要特性与优势
- 高能量吸收能力：600 W 峰值脉冲功率，能有效吸收短时大幅度电涌，保护下游电路。
- 低反向漏流：在额定工作电压下，反向电流仅 1 μA，有利于低功耗系统的稳定性。
- 宽温度覆盖：-65 ℃ 至 +150 ℃ 的工作温度范围，适合严苛环境与工业级应用。
- 双向保护：适用于交流线路或可能正负翻转的电路，不需外加极性判断电路。
- SMB 封装：体积与散热兼顾，易于在 PCB 上安装与回流焊接。
四、典型应用场景
- 电源线和总线防护（14V 级别汽车电子子系统、工业电源）
- 通信与数据接口防雷击和静电放电（需配合限流元件）
- 继电器、传感器、控制模块的浪涌保护
- 电池管理与充电设备的输入侧防护
五、使用建议与注意事项
- 布局靠近被保护端口：将 TVS 尽量靠近需保护点放置，缩短导线长度以降低寄生感抗。
- 散热考虑：高能量脉冲时器件产生热量，建议在 PCB 上增大铜箔散热区并使用通孔/热过孔改善散热。
- 脉冲规范匹配：Ppp 等参数基于特定脉冲波形测量，实际设计时应参照厂家数据表中脉冲标准（如 10/1000 μs 或 8/20 μs）确认能量承受能力。
- 避免长期承受脉冲：虽能承受短时大能量冲击，不建议器件长期反复工作在额定脉冲极限，必要时采用级联保护或限制电流元件。
- 焊接工艺：遵循 SMB 封装回流焊工艺规范，避免超温或长时间加热以保证可靠性。
六、检索与替代
SMBJ14CA/TR13 适用于需 14V 级稳态防护的设计。选型时可根据钳位电压、脉冲功率与封装尺寸与其他厂商同类产品对比，确保击穿特性与系统安全裕量满足实际工况。
如需完整电气特性曲线、脉冲测试条件及封装尺寸，请参考 Brightking 官方数据手册或联系供应商获取样品与技术支持。

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.
