SMCJ22CA/TR13 产品概述

一、产品简介

SMCJ22CA/TR13 是台湾君耀(Brightking)推出的一款双向瞬态电压抑制二极管(TVS),封装为 SMC(DO-214AB)。该器件针对瞬态过电压(如雷击、开关瞬变、电磁脉冲等)提供快速钳位保护,常用于电源线、通讯接口及工业/汽车电子的浪涌防护。典型静态参数:反向截止电压 Vrwm = 22V、击穿电压 VBR = 24.4V、钳位电压 Vc = 35.5V、峰值脉冲电流 Ipp = 42.3A、峰值脉冲功率 Ppp = 1.5kW,工作温度范围 -65℃ 至 +150℃,静态漏电流 Ir = 1µA(典型)。

二、主要特性

  • 双向结构:对正负方向的瞬态电压均能对称钳位,适合交流线路或可能出现双向极性冲击的场合。
  • 高浪涌能量吸收:标称峰值脉冲功率 1.5kW,能承受短时大能量脉冲(在厂方测试条件下)。
  • 有效钳位:在指定峰值冲击电流下钳位电压约 35.5V,可将过高电压限制在器件和后级电路可承受的范围内。
  • 宽温度范围:-65℃~+150℃,适应严苛环境与工业级应用。
  • 低漏电流:在工作电压下漏电低(Ir ≈ 1µA),对静态功耗和精密电路影响小。

三、典型应用场景

  • 24V 类电源总线和工业控制设备的浪涌保护;
  • 工业通讯接口(如 RS-485、CAN 等)与电源线的防雷防突波;
  • 电池管理、逆变器前端以及电源适配器的输入端保护;
  • 需要双向保护的信号线或对地对称瞬变环境。

四、使用建议与设计注意事项

  • 放置位置:尽量靠近被保护器件或电源入口,减少环路电感以提高抑制效果。
  • 接地设计:对于对地钳位型保护,确保接地回路低阻抗、宽铜箔或多点焊接以便快速分流脉冲能量。
  • 热散与PCB 布局:SMC 封装散热通过焊盘传导,建议在焊盘下方或背面增加散热铜箔与过孔,便于热量扩散。
  • 额定选择:Vrwm(22V)应高于正常工作电压,但与系统允许的最高电压保持合理裕量;如系统仅出现单方向过压,可优先考虑单向 TVS 以获得更低钳位。
  • 重复冲击:若产品经常遭受高能脉冲,需评估器件寿命并考虑更高功率等级或外部串联限流器件来分摊能量。

五、封装与可靠性

SMC(DO-214AB)为常见的表面贴装功率封装,适合回流焊工艺。Brightking 品牌在材料与工艺上具备工业级质量控制,器件通常满足焊接温度、热冲击及高低温储存的可靠性测试要求。选型时可向供应商索取详细的规格书(包括测试波形、测试条件、典型曲线和封装尺寸)以便完成可靠性验证与设计准入。

六、选型要点总结

  • 若需保护 24V 类电源或可能出现双向瞬变的应用,SMCJ22CA/TR13 是常用的中高功率 TVS 方案;
  • 确认系统的最大工作电压与浪涌能量分布,确保 Vrwm、Vc 与 Ppp 能满足实际工况;
  • 合理的 PCB 布局与散热设计对器件性能与寿命至关重要。

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
