SMBJ60A 产品概述

一、主要参数与特性

SMBJ60A 是 BORN(伯恩半导体)出品的一款单向 TVS(瞬态抑制二极管),封装为 SMB(DO-214AA)。主要电气参数如下:

  • 极性:单向
  • 反向截止电压 (Vrwm):60 V
  • 击穿电压 (Vbr):66.7 V
  • 钳位电压 (Vcl @ Ipp):96.8 V
  • 峰值脉冲电流 (Ipp):6.2 A
  • 峰值脉冲功率 (Ppp):600 W(10/1000 μs 波形)
  • 反向漏电流 (Ir):1 μA(在 Vrwm 条件下)

该器件针对工业级瞬态浪涌和脉冲能量设计,能在 10/1000 μs 波形下吸收高达 600 W 的电能脉冲,钳位电压与峰值电流配合良好,适合对高能量短时过电压进行保护。

二、工作原理与电气行为

SMBJ60A 在正常工作电压下呈高阻态,反向漏电流极小(约 1 μA),不会影响电路正常运行。当出现超过击穿电压的瞬态过压时,二极管进入雪崩导通状态,将瞬态能量钳位并引入地回路,从而保护后级器件。单向器件在正向瞬态时表现为低阻钳位,负向瞬态则由器件的正向二极管特性限制,应避免在交替电压系统中直接替代双向器件。

三、典型应用场景

  • 工业电源和控制设备的浪涌保护(直流 24V / 48V / 60V 级别)
  • 通信设备与基站的电源输入防护
  • 电机驱动与继电器驱动电路的瞬态抑制
  • 汽车电子(非直接替代 ISO/汽车级规范前需核对温度与冲击要求)
  • 电力监控、安防与仪器仪表的输入保护

四、封装与安装要点

SMB(DO-214AA)封装利于表面贴装与自动化生产,推荐 PCB 布局要点:

  • 尽量缩短器件到被保护节点的导线长度,减少回路感抗
  • 器件底部与铜箔保持良好热连接,必要时在焊盘周围增加散热铜箔和过孔
  • 对于高能脉冲环境,布置旁路电容和滤波器协同工作以降低残压

五、选型与使用建议

  • 将 Vrwm 作为稳态工作电压的上限,实际系统工作电压应低于 60 V;若系统稳态电压接近 Vrwm,应选更高 Vrwm 等级器件以保证可靠性。
  • 峰值脉冲功率 600 W 为单次脉冲能力,不可作为连续功耗指标。若有重复脉冲或高频冲击,应按热累积和平均功率进行降额设计。
  • 单向 TVS 适用于直流系统或需要单向钳位的场合;交流或双向瞬态需选择相应双向型号。

六、注意事项与可靠性

  • 环境温度、焊接温度和机械应力都会影响长期可靠性,建议按厂家推荐的回流曲线和机械应力限制操作。
  • 对关键应用建议进行实际系统级脉冲测试(10/1000 μs 或 IEC 标准波形)以验证钳位效果与热稳定性。
  • 选用 BORN(伯恩) SMBJ60A 时,应确认供货批次与技术规格一致,并在重要项目中保留测试与样件验证记录。

SMBJ60A 以其 60 V 的工作界限、接近 100 V 的钳位能力和 600 W 的单脉冲吸收能力,适合用于中高电压直流系统的瞬态保护,是工业与通信等领域抑制浪涌、保护敏感器件的实用选择。

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
