SA5.0CA/B 产品概述
一、概述
SA5.0CA/B 是 Brightking（台湾君耀）推出的双向 TVS 二极管，采用玻璃钝化结工艺，专为瞬态过电压保护设计。器件在 10/1000μs 波形下可承受高达 500W 的峰值脉冲功率（重复率/占空比 0.01%），具有快速响应与优异的钳位能力，适合对 5V 及 ±5V 类信号和电源线路的保护需求。
二、核心性能参数
- 极性：双向
- 反向截止电压 Vrwm：5V
- 击穿电压 VBR（典型）：6.4V
- 钳位电压 Vc（典型）：9.2V
- 峰值脉冲电流 Ipp（10/1000μs）：55.4A
- 峰值脉冲功率 Ppp（10/1000μs）：500W（占空比 0.01%）
- 反向电流 Ir：典型约 600μA（测试条件不同会有差异；在某些高于 10V 的条件下典型 IR <1μA）
- 封装：DO-15（轴向）
三、主要特点
- 玻璃钝化结：提高器件长期稳定性与可靠性，降低漏电流漂移。
- 低增量浪涌电阻：在冲击能量下能保持较低压降，提升被保护线路的安全裕度。
- 出色的钳位能力：在大电流冲击时将电压限制在可接受范围内，保护后级器件。
- 快速响应：对静电放电和快速瞬变具有快速钳位响应。
- 高能量承受：500W 峰值能力适合电源与 I/O 接口的强瞬态保护。
四、典型应用场景
- I/O 接口保护：USB、串口、通信接口等易受浪涌冲击的信号线。
- AC/DC 电源端保护：输出端或辅助电源线路的浪涌抑制。
- 工业控制与消费电子：需在有限空间内实现强瞬态防护的应用。
五、安装与使用建议
- 尽量靠近受保护端口或器件放置 TVS，以减少寄生感抗导致的钳位降低。
- 与串联阻抗（如熔断器、限流电阻）配合使用，可在重复冲击场景下分担能量并提升整体可靠性。
- 在高频或严格漏电要求的场合，注意 Ir 随测试电压和温度的变化，必要时选型时核对具体测试条件。
- DO-15 轴向封装适合穿孔安装，便于机械强度要求高或散热需求的场合。
六、可靠性与选型提示
- 由于峰值能量依赖波形（10/1000μs）与占空比，设计时请按实际浪涌谱进行裕量设计。
- 若系统对静态漏电流要求极低，需关注具体测试条件或考虑其他漏电更低的 TVS 型号。
- Brightking（台湾君耀）提供的 SA5.0CA/B 在工业应用中表现稳定，适合对 5V 系统进行稳健的瞬态过压保护。

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.
