SMAJ36A 产品概述

一、概述

SMAJ36A 是 BORN(伯恩半导体)推出的一款单向瞬态电压抑制二极管(TVS),采用 DO-214AC(SMA)封装,专为保护对瞬态过电压敏感的直流电源和信号线设计。该器件在承受工业脉冲或雷击类瞬态时能快速夹紧电压,保护下游器件免受过压损坏。

二、主要参数

  • 类型:TVS,单向(极性单向)
  • 反向截止电压(Vrwm):36 V
  • 击穿电压(Vbr):40 V(典型/标称)
  • 钳位电压(Vcl):58.1 V(在标称峰值脉冲电流下)
  • 峰值脉冲电流(Ipp):6.9 A
  • 峰值脉冲功率(Ppp):400 W(基于 10/1000 µs 波形)
  • 反向电流(Ir):1 µA(在 Vrwm 条件下)
  • 封装:DO-214AC(SMA)
  • 品牌:BORN(伯恩半导体)

三、特性与优势

  • 响应速度快:TVS 器件在纳秒级响应,能在瞬态上升初期迅速导通,钳位系统电压。
  • 高能量吸收:在 10/1000 µs 波形下可承受 400 W 峰值功率,适合处理较长时间的脉冲能量(例如工业浪涌)。
  • 低漏电流:在标称 Vrwm 下漏电小(约 1 µA),对待机功耗影响微小,适用于对待机电流敏感的应用。
  • 紧凑封装:DO-214AC(SMA)体积小,易于表面贴装,便于自动化生产与替换。

四、典型应用

  • 汽车与商用车 24V/36V 电源保护(如电控单元、传感器供电线)
  • 工业控制设备和动力总线防护(PLC、驱动器、继电器线圈)
  • 通信与电源模块的输入端浪涌保护
  • 充电设备、逆变器及其他对瞬态过压敏感的直流供电场景

五、选型与设计注意

  • 匹配 Vrwm:选择 Vrwm(36 V)应高于系统正常工作电压且保有余量,例如在 24 V 系统或 36 V 总线中使用,但不宜在高于 Vrwm 的连续电压下长期工作。
  • 钳位电压与下游器件承受能力:钳位电压 58.1 V 表示在峰值脉冲条件下夹紧电压,设计时需确保被保护器件能承受该短时电压。
  • 脉冲规格与可靠性:Ppp=400 W 为单次或短时脉冲能力,若需承受重复脉冲,应参考厂商重复脉冲曲线并做热耗散评估。
  • 热与版图管理:在高能量吸收场合推荐在器件周围留出足够铜箔和热流路径,必要时采用热过孔,缩短导线以降低电感。
  • 单向器件注意极性:接线时保证 TVS 的极性正确(正极连接电源正端/被保护节点),否则无法发挥保护作用或造成短路。

六、封装与可靠性、订购信息

  • DO-214AC(SMA)封装便于手工焊接和贴片,适配常见 PCB 布局与夹持工具。
  • BORN(伯恩半导体)提供的 SMAJ36A 适用于批量自动化装配,建议在采购时确认生产批次与封装标识以保证一致性。
  • 订购时可按型号 SMAJ36A(BORN)/SMAJ36A-BORN 查询库存与技术资料,必要时与供应商确认器件在特定温度与测试条件下的具体参数。

总结:SMAJ36A 是一款面向中等电压直流系统的单向 TVS,具有快速响应、较高能量吸收能力和低漏电流等优点,适合用于 24V/36V 等工业、汽车和通信电源的浪涌保护。设计时需重点考虑钳位电压、脉冲能量和热管理以确保长期可靠运行。

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
