SMAJ36A TVS二极管产品概述

一、产品核心定位与典型应用场景

SMAJ36A是一款单向瞬态抑制二极管(TVS),核心功能是为电子电路提供静电放电(ESD)和浪涌过压保护,避免敏感元器件(如MCU、传感器、接口芯片等)因过压冲击损坏。其典型应用覆盖三大领域:

  1. 消费电子:手机、平板、笔记本电脑的USB接口、充电端口保护,防止静电(8kV接触放电)或电源波动击穿内部电路;
  2. 工业控制:PLC、传感器模块的信号/电源线路保护,适应工业现场的宽温(-55℃~150℃)与电磁干扰环境;
  3. 通信设备:路由器、交换机的以太网接口、电源输入保护,抵御雷击浪涌与电快速瞬变脉冲(EFT)。

二、关键电气参数深度解析

SMAJ36A的参数设计精准匹配中压电路的保护需求,核心参数及实际意义如下:

  • 反向截止电压(Vrwm=36V):正常工作时可承受的最大反向电压(不导通),需与电路正常工作电压(如30V以内)匹配,避免误触发;
  • 击穿电压(Vbr=44.2V):反向电压超过此值时,器件快速导通(ns级响应),将过压钳位至安全范围;
  • 钳位电压(Vc=58.1V):10/1000μs脉冲波形下的实际钳位电压,需低于被保护器件的最大耐压(如MCU耐压60V),确保核心电路安全;
  • 峰值脉冲电流(Ipp=6.9A):对应波形下的最大浪涌电流容量,可应对常见静电与小功率浪涌;
  • 低反向漏电流(Ir=5μA):正常工作时漏电流极小,不影响电路功耗与信号完整性;
  • 宽温范围(-55℃~+150℃):覆盖工业高温、低温环境(如汽车发动机舱、北方户外设备),可靠性稳定。

三、封装形式与工艺优势

SMAJ36A采用SMA(DO-214AC)表面贴装封装,具备三大实用优势:

  1. 小体积高密度:封装尺寸约2.7×1.6mm,适合手机、可穿戴设备等小型化PCB设计,节省布局空间;
  2. 自动化适配:表面贴装工艺兼容回流焊(260℃高温)、波峰焊,便于批量生产,降低制造成本;
  3. 环保与可靠性:符合RoHS无铅要求,封装机械强度高,长期工作无失效风险。

四、品牌与品质保障

SMAJ36A由国内半导体厂商Slkor(萨科微) 生产,该品牌专注功率器件与保护器件研发10余年,产品具备:

  • 认证背书:部分批次符合AEC-Q101汽车级标准(适配汽车电子场景),通过ISO9001质量管理体系认证;
  • 工艺成熟:采用先进的芯片制造与封装技术,参数一致性好,批量供货稳定;
  • 应用验证:已广泛应用于国内多家消费电子、工业企业,市场反馈可靠性高。

五、选型与应用注意事项

使用SMAJ36A需注意以下细节,确保保护效果:

  1. 极性匹配:单向TVS需注意极性(阴极接电源正/信号正,阳极接地),反向连接会失去保护作用;
  2. 电压匹配:Vrwm需高于电路最大工作电压(如电路电压≤35V可选36V),钳位电压需低于被保护器件耐压;
  3. 脉冲功率验证:若电路可能遭遇大功率浪涌(如雷击),需结合并联TVS或串联保险丝增强防护;
  4. 环境适配:-55℃~150℃宽温满足大部分场景,若温度超过需选用更高温规格器件。

总结

SMAJ36A是一款高性价比单向TVS管,参数精准、封装紧凑、可靠性强,可有效解决电子设备的静电与浪涌防护问题,适合消费电子、工业、通信等多领域批量应用。

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
