SMAJ100A/TR13 — 100V 单向 TVS 二极管 产品概述
一、产品简介
SMAJ100A/TR13 是台湾君耀（Brightking）出品的一款单向瞬态电压抑制（TVS）二极管，封装为SMA（DO-214AC）。器件为单向结构，适用于对直流或单向脉冲线路的浪涌与静电放电（ESD）保护。其标称反向截止电压（Vrwm）为100V，击穿电压（Vbr）约111V，能够在过压瞬态时迅速钳位，保护后端敏感电路不受高压冲击。
二、关键电气参数
- 极性：单向
- 反向截止电压 Vrwm：100V
- 击穿电压 Vbr：111V（典型）
- 钳位电压 Vc：162V（峰值钳位）
- 峰值脉冲电流 Ipp：2.5A（器件承受的最大瞬时脉冲电流）
- 峰值脉冲功率 Ppp：400W（在标准测试条件下的峰值耗散能力）
- 反向漏电流 Ir：1 μA（在 Vrwm 条件下的典型漏电）
- 工作温度范围：-65℃至 +150℃
以上参数表明该器件在100V工况下具有较低的漏电、较高的钳制能力，适合中高电压直流系统的瞬态防护。
三、典型应用场景
- 工业电源与配电系统的浪涌保护，特别是直流总线或高压供电线路；
- 通信基站、电源模块和逆变器等设备的输入端防护；
- 继电器驱动、马达控制器等需要承受开关瞬态的电路；
- 需要在高温或严苛环境下可靠工作的嵌入式系统与测控设备。
四、选型与使用建议
- 若工作电压长期接近100V，应确认器件在该电压下的漏电与温漂是否满足系统要求；1 μA 的反向电流适合对漏电敏感的应用，但在高温下应复核规格表；
- 钳位电压162V表示在峰值脉冲作用下被保护点仍可能出现较高电压，应评估后级元件承受能力；若后端器件耐压低于钳位值，应考虑并联更大功率或更低钳位的TVS；
- 安装时注意SMA封装的焊盘尺寸与热散逸路径，良好的铜箔与散热设计有助于提高脉冲承受能力与长期可靠性；
- 单向产品在正向瞬态下导通，请按极性正确焊接（通常有标识极性端）。
五、可靠性与环境适应
SMA 封装（DO-214AC）具备机械强度与可焊性优势，器件的工作温度范围宽（-65℃~+150℃），适合高低温环境。对于要求长期稳定性的系统，应关注瞬态能量分布、重复浪涌次数以及器件的热管理。出于库存与供应管理考虑，可参考 Brightking 的包装与出货规格（TR13 表示托盘或卷带包装方式），便于生产线贴装。
六、结论
SMAJ100A/TR13 是一款针对100V 直流或高电压瞬态防护设计的单向 TVS，具备较低漏电、高钳位能力和较宽工作温度范围。其 400W 峰值脉冲功率与 2.5A 峰值脉冲电流使其适合工业与电源防护场景。选型时应综合评估系统工作电压、钳位容忍度与热散逸条件，确保在实际浪涌事件中提供有效保护。若需要更详细的典型波形、测试条件或封装图，请咨询供应商获取完整规格书。

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.
