SMBJ85A/TR13 产品概述
一、产品简介
SMBJ85A/TR13 是 Brightking（台湾君耀）推出的一款单向瞬态电压抑制二极管（TVS），针对表面贴装（SMB / DO-214AA）应用而设计。器件采用低外形封装、玻璃钝化结结构，具有优异的浪涌吸收能力与低反向漏电特性，适合对电路板空间和抑制性能有较高要求的场合。
二、主要性能参数
- 极性：单向
- 反向截止电压 Vrwm：85 V
- 击穿电压 VBR：94.4 V（标准测量条件）
- 钳位电压 Vc：137 V（峰值脉冲时）
- 峰值脉冲电流 Ipp：4.4 A
- 峰值脉冲功率 Ppp：600 W
- 反向电流 Ir：1 μA（在指定 Vrwm 下）
- 工作温度范围：-65 ℃ 至 +150 ℃
- 封装：SMB（DO-214AA） 适配标准回流焊工艺
三、产品特性与优势
- 低外形、表贴封装：便于在紧凑型电路板上布局，节省空间并兼容自动化贴装流程。
- 玻璃钝化结：提高器件稳定性与耐久性，降低长期泄漏和漂移。
- 低电感设计：快速响应高频瞬态，适合高速接口和电子开关电路。
- 良好钳位能力：在过压事件中维持较低钳位电压，保护后级元件免受损害。
- 内置应力消除功能：提升对热循环和机械应力的耐受性，增强可靠性。
四、典型应用场景
- I/O 接口保护：USB、串口、以太网等数据线的浪涌与静电防护。
- AC / DC 电源线防护：电源输入端的瞬态抑制与浪涌吸收。
- 工业与通信设备：要求宽温域、长寿命及高可靠性的电源与信号链路。
五、设计与选型建议
- 布局建议：将 TVS 靠近被保护端口或连接器放置，缩短引线长度以降低寄生电感。
- 极性注意：单向 TVS 在电路中需按极性正确连接（阳极接地或电源负端，阴极接保护线上）。
- 热管理：在频繁或高能量浪涌环境，应考虑散热与散流路径，避免长期过载。
- 测试与验证：在最终系统中验证钳位、电流承受能力及对短时重复冲击的稳定性。
六、可靠性与封装信息
SMBJ85A/TR13 提供符合表贴加工的 SMB 封装，适用于回流焊和自动化生产线。宽温工作范围（-65 ℃ 至 +150 ℃）确保在严苛环境下依然保持性能稳定，适合工业级应用。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
