SMAJ64CA/TR13 产品概述
一、产品简介
SMAJ64CA/TR13 是 Brightking（台湾君耀）出品的一款双向瞬态电压抑制器（TVS），封装为 SMA（DO-214AC）。器件专为抑制瞬态过压、保护电源与敏感器件而设计，适用于需要双向保护的直流母线与交流瞬态场合。
二、主要参数（典型/额定）
- 极性：双向（无极性方向，双向钳位）
- 反向截止电压 Vrwm：64 V
- 钳位电压 Vc：103 V（在峰值脉冲电流条件下的典型值）
- 峰值脉冲电流 Ipp：3.9 A
- 峰值脉冲功率 Ppp：400 W
- 击穿电压 Vbr：71.1 V（标称）
- 反向电流 Ir：≤1 μA（在 Vrwm 条件下典型）
- 工作温度：-65 ℃ ～ +150 ℃
- 封装：SMA（DO-214AC）
- 类型：TVS，型号 SMAJ64CA/TR13
三、特点与优势
- 双向保护：针对正负极性瞬态电压均能快速钳位，适合交流或双向直流抑制场合。
- 高能量吸收能力：400 W 峰值脉冲功率与 3.9 A 峰值脉冲电流，能在短时浪涌中有效吸收能量，保护后端电路。
- 低漏电流：在工作电压下反向电流≤1 μA，有利于低功耗系统长期稳定工作。
- 宽温度范围：-65～150 ℃ 适应极端环境与工业级应用。
四、典型应用
- 48 V 直流母线与 PoE、通信设备的浪涌保护（64 V 工作电压适配 48 V 系统）
- 工业控制、电源输入端抑制浪涌与浪费脉冲
- 逆变器、储能与充电设备输入侧瞬态保护
- 需要双向钳位的信号与小功率电源保护场合
五、封装与安装注意
- SMA（DO-214AC）为表面贴装封装，适合自动贴装与回流焊工艺。
- 双向器件无极性标识，安装方向不影响工作，但应确保焊点可靠、散热良好。
- 建议遵循厂商回流焊温度曲线与时长，避免长时间高温导致器件退化。
- 在高能量冲击应用中，配合熔断器或限流元件使用以减小重复冲击对器件的累积损伤。
六、可靠性与使用建议
- 避免长期在接近 Vrwm 或高温下工作以减小漏电与热应力。
- 对于频繁或高能量的浪涌，应考虑并联更高能量等级 TVS 或在前端增加串联阻抗以分担能量。
- 在设计 PCB 布局时，尽量缩短 TVS 至保护点的回路长度，降低寄生电感以提高钳位效率。
SMAJ64CA/TR13 提供稳定的双向浪涌抑制性能，适合各类工业与通信系统的输入保护需求。如需器件样片、详细电气曲线或封装尺寸图，请联系 Brightking（台湾君耀）或其授权分销商获取原厂资料与应用指南。

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.
