SMBJ36CA 产品概述

一、产品简介

SMBJ36CA 是扬杰(YANGJIE)推出的一款双向瞬态电压抑制器(TVS),封装为 SMB(DO-214AA)。该器件用于吸收瞬态过电压与浪涌能量,保护敏感电子电路免受雷击、开关瞬变或电源浪涌的损害。器件为双向,适用于交流或双向脉冲环境。

二、主要电气参数

  • 反向截止电压(Vrwm):36 V(器件在工作状态下的最高稳态电压)
  • 击穿电压(Vbr)典型值:44.2 V(击穿区起始)
  • 钳位电压(Vc)典型值:58.1 V(在峰值脉冲电流下的钳位电压)
  • 峰值脉冲功率(Ppp):600 W(基准波形 10/1000 μs)
  • 峰值脉冲电流(Ipp):10.3 A(对应 Ppp 条件下的电流)
  • 反向漏电流(Ir):5 μA(在 Vrwm 条件下的漏电)
  • 极性:双向(Bidirectional)

三、典型应用场景

  • 工业电源与配电系统(36 V 级别保护)
  • 电机控制、驱动器接口与传感器线路防护
  • 通信与数据端口防雷、防浪涌保护
  • 电池管理与充放电回路过压保护(双向浪涌)
  • 需要吸收大能量脉冲(10/1000 μs 波形)的场景

四、优势与特性

  • 高能量吸收:600 W(10/1000μs)适合较长持续时间的浪涌能量吸收。
  • 低静态漏电:5 μA 的漏电有利于低功耗系统。
  • 明确的钳位特性:58.1 V 的钳位电压可在保护电压范围内限制瞬态幅值。
  • SMB 封装,便于自动贴装与散热管理。

五、选型与使用建议

  • 工作电压选择:Vrwm(36 V)应高于系统正常工作电压,推荐在实际最大工作电压之上留有裕量。
  • 考虑钳位:确保 58.1 V 的钳位电压不会超过被保护器件可以承受的最大耐压。
  • 多次冲击与热耗散:600 W 为单次峰值指标,重复或连续浪涌时应考虑热量累积和器件热击穿,必要时并联或选用更高能量级产品。
  • 布局:TVS 尽量靠近被保护引脚放置,走线短且宽以降低寄生电阻和电感,焊盘金属量充足以利散热。
  • 双向注意:适用于无固定极性的线路,若用于直流单极场合可优先考虑单向TVS以获得更低的钳位电压。

六、封装与可靠性

SMB(DO-214AA)封装适合自动贴片生产,具有良好机械强度和散热能力。焊接后应避免过度热循环,储存与使用环境建议遵循厂商温度和湿度规范,以保证长期可靠性。

七、结论

SMBJ36CA 是一款面向 36 V 等级线路的高能量双向 TVS,适合工业、通信与电源防护等场景。选型时需综合考虑系统最大工作电压、被保护器件耐压和热管理策略,以确保最佳保护效果与长期稳定性。若需更高重复能量能力或更低钳位,请参考厂商的同系列其他型号或并联配置方案。

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
