SMCJ24CA-AT/TR13 产品概述
一、产品简介
SMCJ24CA-AT/TR13 是台湾君耀（Brightking）出品的一款双向瞬态电压抑制器（TVS），封装为 SMC（DO-214AB）。器件专为抑制浪涌与瞬态过电压设计，在工业电源、通讯接口和车辆电子等应用中可提供可靠的过电压保护。
二、主要电气参数
- 极性：双向
- 反向截止电压 Vrwm：24 V
- 击穿电压 Vbr（典型）：26.7 V
- 钳位电压 Vc（在额定脉冲条件下）：38.9 V
- 峰值脉冲电流 Ipp：38.6 A
- 峰值脉冲功率 Ppp：1.5 kW
- 反向漏电流 Ir：1 μA（典型）
- 工作温度范围：-55 ℃ ~ +150 ℃
以上参数表明该器件在承受短时高能量脉冲时能将电压钳位于安全范围内，同时在静态条件下保持极低的漏电流。
三、典型应用场景
- 24 V 工业电源总线防护与瞬态抑制
- 继电器线圈、伺服驱动及逆变器的输入保护
- 通信接口、RS-485、CAN 总线等差分信号线的浪涌防护（双向结构适合正负摆幅抑制）
- 电池系统、充电回路及电机控制回路的浪涌防护
四、布局与散热建议
- 器件应尽量靠近受保护端口或接地节点放置，以缩短走线长度，降低寄生电感带来的钳位升高。
- SMC 封装具有较大的焊盘和散热能力，建议在焊盘处使用铜箔过孔或散热铺铜以提高能量分散能力。
- 对高能量脉冲应用，确保 PCB 有足够的绝缘间距和爬电距离，避免表面放电或击穿。
五、选型与可靠性注意事项
- 钳位电压 38.9 V 意味着被保护电路需能承受该水平的短时电压；对更敏感器件应考虑级联保护或更低钳位值的方案。
- 峰值脉冲电流 38.6 A 与峰值功率 1.5 kW 为器件在厂方指定脉冲测试条件下的能力上限，持续或重复超额冲击会缩短寿命或导致失效。
- 双向器件在交流及双极性脉冲场合具有优势，若保护单极直流线路可考虑单向型以降低静态钳位。
- 存储与焊接应遵循厂家湿敏等级与回流曲线，避免过热或潮湿引起性能退化。
六、包装与订购信息
- 封装：SMC (DO-214AB)，适合自動化贴装与手工焊接。
- 型号后缀 /TR13 常用于卷带包装（Tape & Reel），便于 SMT 生产线直接上料。
- 选型时请参考厂商完整数据手册以获取详细脉冲测试波形、典型特性曲线及机械尺寸信息，并按应用环境余量选择合适型号。
如需电气特性曲线、典型钳位随电流变化图或 PCB 布局示意图，可提供更详细的工程支持资料与参考建议。

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.
