SMAJ6.5CA 产品概述
一、产品概述
SMAJ6.5CA 是扬杰（YANGJIE）出品的双向瞬态抑制二极管（TVS），封装为 DO-214AC（SMA）。该器件针对瞬态过电压和浪涌脉冲提供有效钳位保护，适用于电源轨、通讯接口及工业控制等对瞬态抑制有严格要求的场景。
二、主要参数
- 极性：双向（Bidirectional）
- 反向截止电压 Vrwm：6.5 V
- 击穿电压 Vbr：7.98 V（典型）
- 钳位电压 Vc：11.2 V（在指定峰值脉冲条件下）
- 峰值脉冲电流 Ipp：35.71 A
- 峰值脉冲功率 Ppp：400 W（10/1000 µs 波形）
- 反向漏电流 Ir：500 µA（在 Vrwm 条件下）
- 类型：TVS，型号 SMAJ6.5CA
三、性能与特点
- 双向结构可在正负极性瞬态下均提供对称钳位，适合交流或双向干扰场合。
- 400 W（10/1000 µs）高能量吸收能力，能够承受雷击残压及电网切换引起的长冲击脉冲。
- 钳位电压 11.2 V 在 35.71 A 峰值电流下实现对设备的有效保护，兼顾保护性能与前端电路兼容性。
- 漏电流较低（500 µA），利于在低功耗或精密电路中使用。
四、典型应用
- 5 V / 6 V 电源轨保护（如单片机、嵌入式板卡）
- 串口/总线接口防护（RS-232、RS-485、CAN 等）
- 工业控制设备、电源适配器、逆变器输入及输出端防护
- 通讯基站、终端设备的瞬态浪涌防护
五、选型与使用建议
- 若保护对象为 5 V 系统，SMAJ6.5CA 的 Vrwm = 6.5 V 提供较好的工作安全裕度；如系统电压更高，应选择更高 Vrwm 的型号。
- 注意钳位电压对被保护器件承受能力的影响，复杂系统应在实验条件下验证钳位电压与残压。
- PCB 布局应尽量缩短 TVS 与被保护线之间的走线，使用充足的焊盘和散热铜箔以提升能量吸收后散热性能。
- 考虑漏电流对待机功耗的影响，需在低功耗设计中评估 500 µA 的影响。
六、封装与可靠性
DO-214AC（SMA）封装便于自动贴装与回流焊接；封装尺寸适中，便于在空间有限的应用中使用。建议在生产和存储过程中遵循厂家推荐的湿敏等级和回流焊工艺，以保证长期可靠性。对于关键场合，建议对样片进行 IEC/EN 浪涌、ESD（如 IEC 61000-4-2）等实测验证，确保系统整体防护效果。

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.
