SMCJ90CA/TR13 产品概述 — Brightking (台湾君耀)
一、产品简介
SMCJ90CA/TR13 为 Brightking（台湾君耀）出品的双向瞬态电压抑制器（TVS），封装为SMC（DO-214AB）。该器件设计用于抑制高能量瞬态过电压，典型参数包括：反向截止电压 Vrwm = 90V、击穿电压（Vbr）≈100V、钳位电压 Vc（在峰值脉冲条件下）约为146V，峰值脉冲功率 Ppp = 1.5kW，峰值脉冲电流 Ipp ≈ 10.3A，反向漏电流 Ir ≈ 1μA。双向极性使其可对称抑制正负方向的瞬态脉冲，适合交流或双向信号线保护。
二、主要特性
- 双向保护，可同时应对正向与反向瞬态。
- 高峰值吸收能力：Ppp 1.5kW，能承受瞬态浪涌冲击。
- 低钳位电压：在额定脉冲能量下 Vc 约为146V，降低被保护电路的应力。
- 低漏电流：Ir ≈1μA，有利于高阻系统的长期稳定性。
- SMC 封装便于自动贴装和可靠散热。
三、典型应用场景
适用于工业电源、开关电源输出、直流母线保护、逆变器及变频器外围、通信基站和配电箱中对90V等级以上瞬态抑制的场合。双向特性也适合对交流电路或双向数据/信号线的防护。
四、设计与选型建议
- 工作电压选择：Vrwm 90V 代表器件在连续工况下的耐受电压，应选择略高于正常工作电压的型号以避免误触发。
- 钳位与余量：考虑负载耐受电压时，以钳位电压146V为参考，确保后端元件能承受瞬时钳位电压。
- 脉冲规范：峰值功率与电流受脉冲波形和持续时间影响，选型时应参照实际浪涌波形（如8/20μs 等标准）并检查厂家曲线。
- 封装与散热：SMC 封装有一定体积散热能力，但在重复脉冲或高能环境中需保证良好PCB铜箔散热与短回流路径。
五、安装与可靠性注意事项
- 尽量将TVS靠近被保护点布局，走线短、粗、直以降低电感。
- 采用合适的焊接工艺，避免因过热影响器件特性。
- 多次重复浪涌会降低寿命，设计中应评估浪涌频率并留足余量或并联冗余保护。
- 对于关键应用建议进行实际浪涌测试并参照制造商的寿命/热阻曲线。
六、包装与订购信息
型号示例：SMCJ90CA/TR13，TR 表示卷带（Tape & Reel）包装，适合自动贴装。订购时请确认完整料号与包装形式，并索取最新版数据手册以获得详细电气曲线和测试条件。
如需更详细的脉冲测试条件、钳位曲线或封装尺寸图，请告知，将提供对应数据表与应用参考。

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.
