SMBJ30CA 产品概述

一、产品简介

SMBJ30CA 是 RUILON(瑞隆源)推出的一款双向瞬态电压抑制器(TVS),封装为 DO-214AA(SMB)。器件专为针对雷击、静电放电(ESD)、快速瞬态脉冲(EFT)等过电压事件提供稳健的浪涌保护,适用于工业控制、电源接口和通信设备等需要30V等级防护的线路。

二、主要电气参数

  • 极性:双向(双向对称钳位,适合交流或正负突波)
  • 反向截止电压 Vrwm:30V(建议工作电压不超过此值)
  • 击穿电压 Vbr:38.3V(典型)
  • 钳位电压 Vc:48.4V(对应脉冲测试条件)
  • 峰值脉冲电流 Ipp:12.4A(10/1000 μs 波形)
  • 峰值脉冲功率 Ppp:600W(10/1000 μs 波形)
  • 反向电流 Ir:1 μA(在 Vrwm 下)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 符合标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)

三、性能亮点

  • 高能量吸收能力:在 10/1000 μs 波形下可承受 600W 峰值功率和 12.4A 峰值电流,适合电源和远端雷击防护。
  • 低漏电流:典型反向电流仅 1 μA,有利于电源效率与待机功耗控制。
  • 宽工作温度和可靠封装:-55℃~+150℃ 的耐温能力和 SMB 封装适合恶劣环境应用。
  • 符合 IEC ESD/EFT 测试,提升系统抗干扰能力与可靠性。

四、典型应用场景

  • 24V/30V 工业总线和电源接口防护(PLC、驱动模块、传感器供电)
  • 通信端口、以太网供电边缘保护(配合其他保护元件)
  • 电源输入端、逆变器和电源适配器的浪涌保护
  • 需要双向防护的交流或双极性信号线路

五、选型与使用建议

  • 选型时应保证 Vrwm 大于或等于系统最大连续工作电压,且留有一定裕量以避免误触发。对于有反复冲击的场合,建议并联多只器件或选用更高能量等级的 TVS。
  • 布板布局建议:TVS 与受保护端尽量靠近,走线尽量短且宽,使用足够的焊盘和散热铜箔,必要时增加过孔以提高热耗散。
  • 由于为双向类型,无极性安装限制,但仍需注意正确定向放置及与其他保护器件的协同(例如慢熔断器、共模电感)。

六、可靠性与安装注意

  • 建议采用推荐的回流焊工艺,避免超出器件最高温度限制。
  • 在高冲击环境中,考虑机械固定与减震措施以延长可靠寿命。
  • 对于关键系统,建议在设计阶段进行实际浪涌/ESD 仿真与实验验证,确保系统整体防护满足要求。

SMBJ30CA 以其稳定的钳位性能、较高的能量吸收能力与宽温域特性,为 30V 级别的工业和通信场景提供经济且可靠的瞬态过压保护方案。若需更多器件参数(如结电容、典型 I-V 曲线或封装尺寸图),可进一步索取器件数据手册。

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
