SMDJ160CA 瞬态抑制二极管(TVS)产品概述

SMDJ160CA是东沃(DOWO)推出的一款双向瞬态抑制二极管(TVS),采用DO-214AB贴片封装,专为中高压电路的瞬态过压防护设计,具备宽温适应、高脉冲功率承受能力等特点,可有效抑制雷击、静电放电(ESD)、开关浪涌等瞬态干扰,保护后端敏感电子器件。

一、产品核心定位与封装特性

作为双向TVS管,SMDJ160CA无需区分正负极即可实现双向过压保护,简化电路设计;采用DO-214AB(SMA)贴片封装,尺寸紧凑(典型尺寸约3.0×1.5×1.1mm),适配高密度PCB布局,同时支持回流焊、波峰焊等标准贴片工艺,适合自动化生产。

二、关键电气参数详解

SMDJ160CA的电气参数针对中高压防护场景优化,核心参数及意义如下:

  1. 极性与工作电压:双向极性,反向截止电压(Vrwm)160V,即正常工作时可承受的最大反向电压,确保电路在160V以下稳定运行;
  2. 击穿与钳位特性:反向击穿电压178V(过压触发阈值),过压时快速导通,将电压钳位至259V,远低于多数后端器件的耐压极限(如MOS管、IC的300V以上耐压);
  3. 脉冲耐受能力:10/1000μs波形下,峰值脉冲功率(Ppp)达3kW,对应峰值脉冲电流(Ipp)11.58A,可有效吸收常见工业/车载场景的瞬态浪涌;
  4. 漏电流与温度范围:Vrwm下反向漏电流仅2μA,不影响电路正常功耗;工作温度覆盖-55℃~+150℃,符合工业级、车载级宽温要求。

三、典型应用场景

结合参数特性,SMDJ160CA适用于以下场景:

  1. 工业自动化设备:PLC输入输出接口、传感器模块的过压防护,应对现场开关浪涌、雷击干扰;
  2. 电力电子领域:开关电源、逆变器、UPS的AC/DC侧防护,抑制电源瞬态尖峰;
  3. 车载电子系统:车载充电器、电机控制器、CAN总线接口,适配-40℃~+85℃的车载环境;
  4. 通信设备:基站射频模块、光传输设备的电源与信号线路防护,抵御静电与浪涌;
  5. 高端消费电子:大功率电源适配器、户外照明设备的瞬态防护,提升产品可靠性。

四、选型与使用注意事项

  1. 参数匹配原则:
    • Vrwm需大于电路正常工作电压(如120V工作电路选160V足够);
    • 钳位电压需低于后端器件最大耐压(259V适配300V耐压的MOS管/IC);
  2. 安装与焊接:DO-214AB封装需注意焊接温度(回流焊260℃/10s、波峰焊240℃/5s),避免虚焊或过热损坏;
  3. 并联扩容:若需更大脉冲电流,可并联多个SMDJ160CA(双向管无需考虑极性),但需保证各器件参数一致性;
  4. 降额使用:在高温或高脉冲频率场景,建议适当降额(如Vrwm降额至150V以下),延长使用寿命。

SMDJ160CA凭借双向防护、高功率耐受、宽温适配等优势,成为中高压电路瞬态防护的高性价比选择,可满足工业、车载、通信等多领域的可靠性要求。

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.

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
