SMBJ16CA 产品概述

一、产品简介

SMBJ16CA 是台湾迪嘉(TWGMC)出品的一款双向瞬态电压抑制器(TVS),采用SMB表面贴装封装,专为瞬态过压、雷击与电快速瞬变(EFT)等冲击保护设计。器件在工业级与汽车级工作温度下仍能保持稳定工作,适合对抗脉冲能量需求较高的场合。

二、主要性能参数

  • 类型:双向 TVS 二极管(SMBJ 封装)
  • 反向工作电压 Vrwm:16 V
  • 击穿电压(典型):19.7 V
  • 钳位电压(典型):26 V
  • 峰值脉冲功率 Ppp:600 W(10/1000 µs 波形)
  • 峰值脉冲电流 Ipp:23.1 A(对应 10/1000 µs)
  • 结电容 Cj:390 pF(典型)
  • 反向漏电流 Ir:1 µA(在 Vrwm 条件下典型)
  • 工作温度范围:-65 ℃ ~ +150 ℃
  • 极性:双向
  • 封装:SMB(表面贴装)

三、关键特性与优势

  • 高能量吸收能力:600 W(10/1000 µs)能有效吸收来自雷击或工业脉冲的瞬态能量,Ipp 23.1 A 满足中高能量冲击需求。
  • 宽温度范围:-65 ~ +150 ℃,适应严苛的环境温度波动,可靠性高。
  • 低漏电流与较小结电容:Ir 仅 1 µA,有助于降低静态功耗;390 pF 的结电容适合多数电源与信号线保护,但对极高频信号需评估影响。
  • 双向结构:可用于交流或差分线路的双向瞬态抑制,无需额外极性判断,布线更灵活。
  • SMB 封装:易于自动化贴装,散热与机械强度兼顾,适合批量生产的 SMT 工艺。

四、典型应用场景

  • 工业电源保护:控制柜、工控电源、变频器等对雷击或开关瞬变敏感的电源线路。
  • 通信与数据接口:用于模块电源侧或耐冲击要求的差分/对称信号保护(需评估结电容对信号带宽的影响)。
  • 汽车电子(非直接车身关键安全回路):凭借宽温特性,可用于车载电子系统、通讯模块与车载充电设备的瞬态抑制。
  • 消费与电力设备:UPS、路由器、电源适配器等突发过压防护。

五、选型与使用注意事项

  • 根据系统的最大连续工作电压选取 Vrwm(此器件为 16 V),若供电电压接近或超过 Vrwm,应改选更高 Vrwm 型号。
  • 钳位电压为瞬态时的电压限制值,选择时需确保下游元件能承受该钳位电压(本型号约 26 V)。
  • 对高速差分信号在线路保护时,须评估 390 pF 的结电容对信号完整性的影响,必要时考虑更低电容的型号或布置在非信号路径。
  • 布局建议:器件与被保护节点间走线尽量短、宽,减小串联感抗;并配合合适的接地回流路径以提高抑制效率。焊接工艺按SMB封装的回流曲线执行,避免超温或过久预热。

六、封装与可靠性

SMB 封装适合自动贴片与回流焊,机械强度与散热性能平衡良好。TWGMC 品牌管控下料质与一致性可靠,建议在批量应用前做环境应力筛选(如热循环、浪涌耐受测试)以验证在目标系统中的长期稳定性。

如需进一步的典型浪涌曲线、钳位电压随电流的具体数据或封装尺寸图纸,可提供以便完成电路保护方案验证与 PCB 布局优化。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
