SMAJ36A 单向TVS静电浪涌保护器产品概述

SMAJ36A是固得沃克(GOODWORK)推出的一款单向瞬态抑制二极管(TVS),核心用于电子电路的静电放电(ESD)和瞬态浪涌防护,采用SMA(DO-214AC)贴片封装,体积紧凑、性能稳定,适配多种中低压应用场景。

一、产品核心功能与定位

作为TVS器件,SMAJ36A的核心作用是快速响应电路瞬态过压:当电路因静电、雷击、开关切换等产生浪涌时,它能在ns级时间内从高阻态转为低阻态,将过电压钳位在安全范围,避免后端敏感元器件(如MCU、传感器、通信芯片)被击穿损坏。

该产品为单向TVS,仅对反向浪涌(阴极→阳极方向)起保护作用,正向呈普通二极管特性,适合需要单向防护的电路设计。

二、关键电气参数解析

SMAJ36A的参数经过优化,匹配中低压电路防护需求,核心参数及意义如下:

  • 反向截止电压(Vrwm):36V:正常工作时反向承受的最大电压(不导通),要求被保护电路工作电压需低于此值(如12V/24V电路),避免TVS长期导通影响电路。
  • 击穿电压(Vbr):40V:反向电压超此值时,TVS开始击穿进入钳位状态,是“截止→保护”的过渡点。
  • 钳位电压(Vc):58.1V:浪涌到来时,TVS导通后将电路电压稳定在该值(远低于敏感器件击穿电压),是防护效果的核心指标。
  • 峰值脉冲电流(Ipp):6.9A:10/1000μs标准浪涌波形下,TVS能承受的最大峰值电流,适配中等强度浪涌冲击。
  • 峰值脉冲功率(Ppp):400W:浪涌峰值功率(Vc×Ipp),体现器件浪涌耐受能力。
  • 反向漏电流(Ir):5μA:反向截止时漏电流极小,不影响电路正常工作,反映器件绝缘性能。
  • 工作结温范围:-55℃~+150℃:宽温设计,适配工业级、汽车级等恶劣环境(如低温户外、高温机箱)。

三、封装与物理特性

SMAJ36A采用SMA(DO-214AC)贴片封装,具备以下优势:

  • 体积小巧:尺寸约2.5mm(长)×5.0mm(宽)×1.0mm(高),适合高密度PCB设计(如小型工业模块、便携设备);
  • 表面贴装:便于自动化焊接,生产效率高,焊接可靠性好;
  • 引脚兼容:符合SMA标准布局,可直接替换同封装TVS器件,降低设计成本。

四、典型应用场景

结合参数特性,SMAJ36A适用于以下场景:

  1. 工业控制电路:PLC数字I/O接口、传感器信号端口(12V/24V工作电压),现场易出现静电或开关浪涌;
  2. 汽车电子:车载低压控制电路(车身控制器、传感器模块),宽温设计匹配汽车级需求;
  3. 通信设备:12V/24V电源端口、RS485/RS232接口,防止雷击或静电干扰;
  4. 消费电子:中压充电电路(快充适配器输出端)、智能家居控制接口;
  5. 医疗设备:高可靠性信号/电源端口(监护仪传感器接口),宽温适配不同工作环境。

五、应用注意事项

  1. 并联安装:需并联在被保护电路两端(电源-地、信号-地),尽量靠近端口放置,减少引线电感(避免钳位电压升高);
  2. 电压匹配:被保护电路工作电压需低于36V(Vrwm),若接近36V需预留余量;
  3. 焊接规范:焊接温度≤260℃,时间≤3秒,避免热损伤;
  4. 浪涌评估:若浪涌强度超400W峰值功率,可串联限流电阻或并联多个器件提升耐受能力。

SMAJ36A凭借稳定防护性能、紧凑封装和宽温特性,成为中低压电路静电浪涌防护的高性价比选择,覆盖工业、汽车及消费电子等多领域。

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
