SMCJ64A/TR13 产品概述
一、产品简介
SMCJ64A/TR13 为 Brightking（台湾君耀）出品的单向瞬态抑制二极管（TVS），封装为 SMC (DO-214AB)。器件针对瞬态过压与雷击、浪涌等脉冲能量提供快速钳位保护，适用于直流供电轨和通信接口的过电压保护。典型工作平台为 48V / 57V 类电力和通信系统。
二、电气参数要点
- 极性：单向（适用于从正向到地的浪涌钳位）
- 反向工作电压 Vrwm：64V（建议工作电压不超过此值）
- 击穿电压 VBR：71.1V（在制造商规定的测试电流下测得）
- 钳位电压 Vcl：103V（在峰值脉冲电流 Ipp 条件下）
- 峰值脉冲电流 Ipp：14.6A（对应钳位电压测试）
- 峰值脉冲功率 Ppp：1.5kW（制造商测试脉冲条件下的瞬态功率能力）
- 反向漏电流 Ir：≤1μA（在 Vrwm 条件下，体现低泄漏特性）
这些参数反映在遭受短时高能脉冲时，器件能在限定的钳位电压内安全导流并吸收能量。
三、典型应用场景
- 48V/57V 电力与通信设备防护（如基站供电、交换机、PoE 端口）
- 工业控制、电源模块的输入/输出浪涌保护
- 直流母线、配电系统以及需要高瞬态吸收能力的场合
四、选型与系统设计建议
- 工作电压裕量：选择 Vrwm 明显高于正常直流工作电压，避免常态下触发击穿。
- 能量匹配：根据系统可能遭受的浪涌能量，确认 Ppp 与 Ipp 能满足预期冲击（制造商测试脉冲条件需参考数据手册）。
- 并联与冗余：在更高能量场合可采用并联或在前端加装熔断器/限流元件，避免单器件承受超出额定能量。
- 漏流要求：检验 Ir 是否满足系统静态功耗与待机漏电规范要求。
五、封装与安装建议
SMC (DO-214AB) 为常用表面贴装封装，具有良好热散能力。推荐做法：
- PCB 规划短回流路径与足够铜箔面积以帮助热量分散；在需要时添加过孔连接底层散热平面。
- 焊接按照 SMT 常规工艺进行，避免长时间高温停留导致器件性能退化。
- 布局上尽量靠近被保护节点放置，减少寄生电感以优化钳位响应。
六、包装与订购信息
型号 SMCJ64A/TR13 中带卷代码（TR）用于自动贴片生产线，详细包装数量与标识请参阅厂商出货说明或联系销售确认。
结语：SMCJ64A/TR13 提供了对中高电压直流系统的可靠瞬态保护，低漏电、高钳位能力与 SMC 封装使其在工业与通信领域具有较好兼容性。选型与布局时应结合实际浪涌规范与热管理需求进行验证。

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.
