5.0SMDJ90CA 产品概述
一、产品简介
5.0SMDJ90CA 是 Brightking（台湾君耀）推出的一款双向 TVS 二极管，封装为 SMC（DO-214AB），专为高能量脉冲浪涌和静电放电（ESD）保护而设计。器件在直流工作电压（Vrwm）90V 条件下即可提供可靠的过压钳位保护，适合工业供电、通信及防雷防浪涌场合。
二、主要规格
- 极性：双向
- 反向截止电压 Vrwm：90 V
- 击穿电压 V(BR)：约 111 V
- 钳位电压 Vc（Ipp）：146 V
- 峰值脉冲电流 Ipp（10/1000 µs）：34.3 A
- 峰值脉冲功率 Ppp（10/1000 µs）：5 kW
- 反向电流 Ir：约 2 µA（在 Vrwm 条件下）
- 工作温度范围：-55 ℃ ~ +150 ℃
- 防护/测试标准：符合 IEC 61000-4-2（ESD）
- 封装：SMC (DO-214AB)
三、特点与优势
- 大能量吸收能力：10/1000 µs 脉冲下可吸收 5 kW 能量，适合雷击感应和强浪涌场合。
- 低钳位电压：在额定脉冲电流下钳位电压 146 V，可有效限制被保护电路电压应力。
- 双向保护：能够在双向瞬态事件中进行对称钳位，方便用于交流线或需双向防护的直流线路。
- 宽温度性能与低泄漏：-55 ℃ 至 +150 ℃ 工作范围和典型 2 µA 反向泄漏，适合长期可靠运行。
四、典型应用场景
- 工业电源防护（配电模块、稳压电源输入端）
- 通信设备与基站接口保护（防雷及线路异常）
- 太阳能逆变器、光伏汇流箱等光电应用的浪涌抑制
- 高频开关电源、UPS 与电机驱动器的输入/输出防护
五、选型与使用建议
- 若系统工作电压接近或高于 90 V，应确认 Vrwm 与系统最大工作电压匹配，避免长期靠近击穿区工作。
- 布线与封装：将 TVS 靠近被保护器件的输入端或接地端放置，最短且粗的走线可降低感应电感和提升响应速度。
- 散热与寿命：在频繁冲击或高能量环境下应考虑并联或增加散热措施，避免在高温下连续承受脉冲导致性能退化。
- 测试与验证：在实际系统中应做浪涌和 ESD 实测验证，确认钳位电压和泄漏在工作条件下满足需求。
六、可靠性与合规
5.0SMDJ90CA 适配工业级温度与抗扰度要求，经过 IEC 61000-4-2 等电磁兼容测试验证。Brightking 品牌具有成熟的制造与质量控制体系，适合需要长期稳定防护能力的工程应用。
总结：5.0SMDJ90CA 提供大能量、低钳位、双向保护的解决方案，适用于对浪涌和静电抗扰度有较高要求的工业与通信类电路。选择时注意工作电压余量、布板与散热设计，以获得最佳防护效果。

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.
