SMD3216-090N 产品概述
一、产品简介
SMD3216-090N 是东沃（DOWO）推出的一款贴片型两端过压/浪涌保护器件，封装为常用的1206（尺寸 3.2mm × 1.6mm × 1.6mm）。器件以小体积实现较高的脉冲放电能力，适合在有限空间内对数据线、信号线或电源线提供瞬态过电压防护。
二、主要性能参数
- 极数：2（双端/两极结构）
- 直流击穿电压 (Vdc)：90 V（±30%）
- 冲击击穿电压 (Vimp)：700 V
- 脉冲放电电流：500 A（峰值脉冲能力，典型冲击条件下）
- 极间电容：0.3 pF（低电容设计，适合高速信号场合）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 外形尺寸：3.2 mm × 1.6 mm × 1.6 mm（1206 封装）
- 品牌：DOWO（东沃）
注：上述参数应参考实际器件出厂数据表确认，脉冲能力与测试条件（波形、温升、重复频率）密切相关。
三、主要特点
- 小型 1206 封装，便于高密度贴装与自动化生产。
- 高脉冲放电能力（500A 峰值），适合承受瞬态大电流冲击。
- 极间电容低（0.3 pF），对高速信号干扰小，适用于要求带宽的接口防护。
- 宽温度范围，适应多种环境条件。
- 直流击穿电压与冲击击穿电压之间差异，说明对不同试验条件下的耐压表现需按应用场景评估。
四、典型应用场景
- 电源输入端、直流供电保护与浪涌保护。
- 工业控制设备与通信接口的瞬态电压抑制。
- 对电磁瞬态、静电放电或雷击感应类冲击需一定脉冲能力的线路保护。
- 高速信号线或数据总线防护（得益于低极间电容），但应结合信号幅值与器件击穿电压评估兼容性。
五、使用与布局建议
- 尽量靠近被保护端口布置器件，以缩短环路并降低寄生电感。
- 地线或参考地应采用低阻抗回路、短回流路径，避免将噪声引入其他敏感电路。
- 对需连续承受高能量冲击的场合，应配合熔断器、限流电阻或多级保护设计。
- 焊接建议遵循通用1206回流工艺，贴片后避免剧烈热冲击，装配与回流曲线以厂方资料为准。
- 在高可靠性应用（如关键电源、严苛环境）中，建议进行实际浪涌/ESD试验验证。
六、贮存与注意事项
- 存放环境保持干燥、避免潮湿与强腐蚀性气体。
- 装配与测试过程中注意静电防护，防止人为造成击穿或损伤。
- 使用前请参照DOWO提供的详细规格书与质量认证信息，确保器件型号与应用条件匹配。
七、采购与替代
SMD3216-090N 适合在需要兼顾体积、低电容与高脉冲承受能力的场合使用。采购时请确认完整的 Datasheet（测试条件、典型波形、寿命与可靠性数据）与供应商的质量保证。对性能有差异化要求时，可咨询厂商获取针对性推荐或等效型号信息。

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.
