SMAJ6.5A 产品概述
一、产品简介
SMAJ6.5A 是 BORN（伯恩半导体）出品的一款单向瞬态电压抑制器（TVS），采用 SMA（DO-214AC）封装，专为瞬态过压和浪涌电流保护设计。器件响应快、能量吸收能力强，适用于要求可靠过压保护的直流电源、通信接口和汽车电子等场合。
二、主要参数
- 极性：单向
- 反向工作电压 Vrwm：6.5 V
- 击穿电压 Vbr（测量条件）：7.98 V
- 钳位电压 Vc（Ipp）：11.2 V
- 峰值脉冲电流 Ipp：35.7 A（10/1000 μs）
- 峰值脉冲功率 Ppp：400 W（10/1000 μs）
- 反向漏电流 Ir：50 μA（在 Vrwm 条件下）
- 封装：SMA (DO-214AC)
- 类型：TVS（瞬态电压抑制器）
三、主要特性
- 单向结构便于在直流系统中实现高效钳位；正向导通电压低、反向截止稳定。
- 在10/1000 μs波形下具有400 W的冲击能量承受能力，能有效吸收雷击和浪涌能量。
- 钳位电压低（11.2 V），在保护被保护电路的同时减少过压应力。
- 低漏电（50 μA）有利于节能并降低静态功耗影响。
四、典型应用
- 直流电源输入保护（例如 12 V 系统）；
- 通信接口与数据线的防护（RS-485、CAN 总线等）；
- 工业控制与测量设备的浪涌保护；
- 汽车电子的瞬态过压防护（对焊接与布局要求严格时适用）。
五、封装与安装建议
- SMA（DO-214AC）封装适合自动贴片和回流焊工艺；焊盘需按厂商推荐尺寸设计，保证散热与机械强度。
- 建议靠近被保护器件或输入端安放，缩短过电流回路，减少寄生感抗。
- 对于高能脉冲环境，可在 PCB 上增加熔断器或阻焊隔离以分担能量并提高可靠性。
六、选型与注意事项
- 确认系统工作电压与 Vrwm（6.5 V）匹配；若工作电压接近 Vrwm，应选更高 Vrwm 器件以避免误触发。
- 注意钳位电压（11.2 V）是否在系统允许范围内，避免对下游器件造成损伤。
- 在高温或长寿命要求场景，关注封装热阻和实际环境温度对 Ipp/Ppp 能力的影响。
- 如需双向保护，请选择相应双向型号；汽车或更苛刻环境下，选用符合相关认证的产品。
本概述将关键电气参数与应用建议结合，便于工程师快速评估 SMAJ6.5A 在具体设计中的适用性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
