SMAJ58A/TR13 产品概述
一、产品简介
SMAJ58A/TR13 为台湾君耀（Brightking）出品的单向瞬态抑制二极管（TVS），封装为SMA（DO-214AC）。该器件专为中高电压直流系统和电源线上抗浪涌保护设计，能在雷击、开关瞬态和感性负载释放等事件中钳位电压，保护下游元件免受过压损坏。
二、主要电气参数
- 类型：单向 TVS 二极管
- 反向工作电压（Vrwm）：58 V
- 击穿电压（Vbr）：71.2 V（测试条件标注）
- 钳位电压（Vc，Ipp 条件下）：93.6 V
- 峰值脉冲电流（Ipp）：4.3 A（10/1000 µs 波形）
- 峰值脉冲功率（Ppp）：400 W
- 反向漏电流（Ir）：1 µA（在 Vrwm 条件下）
- 工作温度范围：-65 ℃ 至 +150 ℃
三、核心特点
- 高效能钳位：在典型浪涌条件下将电压限制在可接受范围内，避免过压损害敏感器件。
- 低漏电流：1 µA 等级的反向电流适合对待机功耗敏感的电源系统。
- 宽温度适应性：-65 ℃ 至 +150 ℃ 的工作范围适用工业和汽车级环境（需确认具体应用认证）。
- SMA 小型封装：便于线性板级安装和自动化回流焊作业，节省空间。
四、典型应用场景
- 直流电源轨（48 V 或接近 58 V 系统的保护）
- 通信设备电源保护（基站、交换设备）
- 工业控制器、驱动电路的浪涌防护
- 逆变器或电池管理系统的局部保护电路
五、选型与布局建议
- 确认系统额定电压：Vrwm（58 V）应高于电路正常工作电压且留有裕量。
- 浪涌能量评估：10/1000 µs 波形下 Ipp=4.3 A，Ppp=400 W，适用于中等强度浪涌；若系统可能承受更大雷击或传导能量，应选用额定更高的TVS或并联器件并配合熔断器/浪涌抑制器。
- 布局：尽量将 TVS 靠近需保护的输入端或连接器，走线短且宽以减少串联电感；底层回流焊点保证良好热散和机械固定。
- 热管理：在频繁或高能量冲击场合，考虑热量积累与热循环，必要时增加散热措施或选择功率更高的器件。
六、可靠性与环境适应性
器件适合严苛温度环境，封装和材料设计兼顾可靠性。建议在设计阶段参考厂商提供的冲击、湿热、热循环与焊接耐受性测试报告以满足特定行业认证（如需要汽车级 AEC-Q101 认证，请向厂商确认型号是否通过）。
七、封装与订购信息
- 封装：SMA（DO-214AC），适用于自动贴片与回流焊工艺。
- 品牌：Brightking（台湾君耀），型号：SMAJ58A/TR13。
- 订购时请确认封装带卷规格、最低订购量与交期，若用于高可靠性项目，建议索取完整数据手册与测试报告作为设计依据。
如需该型号的典型浪涌波形测试曲线、绝缘与耐压测试条件或与其他保护方案的并联/串联设计示例，我可进一步提供参考电路与布局图。

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.
