5.0SMDJ75CA 产品概述
一、产品简介
5.0SMDJ75CA 是由 BORN（伯恩半导体）推出的高功率双向瞬态电压抑制器（TVS），封装为 SMC (DO-214AB)，专为承受大能量浪涌和保护敏感电子设备设计。器件属于功率 TVS 类，适合工业电源、通信和汽车周边抗浪涌保护场合。
二、主要特性
- 极性：双向（Bi-directional），可同时抑制正、负向瞬态脉冲。
- 反向截止电压（Vrwm）：75 V（稳态工作电压，器件在此电压下泄漏极小）。
- 击穿电压（VBR）：83.3 V（典型击穿区间起始值）。
- 钳位电压：121 V（在标准冲击条件下对瞬态电压的钳制值）。
- 峰值脉冲电流（Ipp）：41.4 A（对应 10/1000 μs 浪涌波形）。
- 峰值脉冲功率（Ppp）：5000 W @ 10/1000 μs（高能量吸收能力）。
- 反向电流（Ir）：≤1 μA（在 Vrwm 下的漏电流，低静态损耗）。
- 封装：SMC (DO-214AB)，适合表面贴装并具备良好导热与散热能力。
三、典型应用
- 工业电源和逆变器的输入/输出端防护
- 通信基站、电信设备的线路防护
- 车载电子（非直接牵涉到强制汽车认证时）和汽车电源总线的瞬态抑制
- UPS、配电模块及其它需要高能量吸收的场合
四、关键电气参数说明
本器件的 Vrwm=75 V 表示在该工作电压下应作为常态使用；VBR=83.3 V 为其进入雪崩区的典型开始值，钳位电压121 V 表征在规定脉冲（10/1000 μs）条件下对过电压的限制能力。Ppp=5000 W 与 Ipp=41.4 A 表明其能承受较大能量的单次或间歇性浪涌，但需避免连续高频脉冲以防器件过热损坏。
五、安装与使用建议
- PCB 布线应尽量缩短 TVS 引线长度，减小串联感抗，提升抑制效果。
- 采用良好散热设计（底铜铺大焊盘、过孔散热等），以便在吸收大能量时降低结温上升。
- 在长期运行环境中，建议为 Vrwm 留有裕量，避免长期处于临界电压附近。
- 对于关键系统，建议并联适当熔断器或限流元件以保护 TVS 免于重复大能量冲击。
六、选型与可靠性参考
选择 5.0SMDJ75CA 时，应确认系统最大工作电压、可能的浪涌能量及允许的钳位电压。对于需要更低钳位或更高频繁冲击耐受力的场合，可考虑并联或级联保护方案。BORN 的 SMC 封装在机械、热性能上适配工业级应用，但最终可靠性还需结合实际环境测试与寿命验证。

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.
