MCR100-6 产品概述

MCR100-6 是华轩阳电子(HXY MOSFET)推出的一款小功率单向晶闸管(SCR/可控硅),采用 SOT-23 小型封装,适用于低功率脉冲触发与交流/直流开关控制场合。器件具有低门极触发电压与微安级门极触发电流,便于与低电平驱动电路直接配合使用,特别适合对体积和成本敏感的消费类与工业控制应用。

一、主要参数(典型/最大值)

  • 门极触发电压 Vgt:800 mV(典型)
  • 门极触发电流 Igt:60 μA(典型)
  • 保持电流 Ih:5 mA
  • 断态峰值电压 Vdrm:400 V
  • 通态峰值电压 Vtm:1.7 V(在指定测试电流下)
  • 最大通态电流 It:800 mA(峰值/短时)
  • 浪涌电流(单脉冲):8 A
  • 门极平均耗散功率 PG(AV):100 mW(器件平均功耗限制)
  • 封装:SOT-23
  • 型号描述:单向可控硅,5 mA 保持,400 V 反向耐压

二、产品特点

  • 低门极触发:Vgt≈0.8 V,Igt 仅 60 μA,适合低电平微控制器或光耦驱动;
  • 高耐压:400 V 的断态耐压满足普通家电与工业电网控制需求;
  • 小封装:SOT-23 适合高密度 PCB 布局与批量消费类应用;
  • 快速响应:适用于脉冲触发与短时浪涌场合;
  • 低功耗门极:PG(AV)=100 mW,门极耗散低,驱动电路设计简便。

三、典型应用场景

  • 小功率交流相控调光与整流(单相半波控制);
  • 电源启动/软启动电路的触发元件;
  • 过压/过流保护与低成本固态继电器;
  • 家用电器、小功率马达控制与灯光调节;
  • 电池充电与断接控制(需注意功耗限制)。

四、设计与使用注意事项

  • 持续导通功耗限制:SOT-23 包装的平均耗散仅 100 mW。注意 Vtm≈1.7 V 在较大导通电流时会产生显著功耗(P≈Vtm×I),因此 800 mA 很可能为短时或脉冲能力,持续工作应严格按照数据手册进行热额定与降额设计。
  • 门极驱动:虽然 Igt 低,但推荐门极驱动留有余量(例如提供数十微安至数毫安的短脉冲)以保证可靠触发与抗干扰能力。可在门极与触发源之间并联小电阻或 RC 以抑制噪声。
  • dv/dt 抗扰动:高 dv/dt 环境下建议在阳极—阴极串联 RC 抑制网络(阻容吸收电路)和必要的箝位元件,以防误触发。
  • 浪涌与保护:器件单脉冲浪涌能力为 8 A,应用中建议使用限流、熔断或热敏保护避免超出器件极限。
  • ESD 与焊接:门极敏感,生产与装配时应做好静电防护;按照推荐回流曲线进行焊接,避免长时间高温。

五、封装与引脚(典型)

SOT-23 三脚封装——典型引脚排列(不同厂家可能有差异,请以最终数据手册为准):

  • Pin1:Gate(门极)
  • Pin2:Cathode(阴极)
  • Pin3:Anode(阳极)

六、热管理与可靠性建议

  • 在 PCB 设计中增加铜箔面积以扩散热量,必要时在阳极处增加散热铜层;
  • 对连续导通应用,推荐选择更大封装或外部散热措施,避免器件长期在高温或功耗接近 PG(AV) 的工况下工作;
  • 在高温环境下对电流进行降额设计,保证长期可靠性。

七、选型建议

  • 若设计为持续大电流导通(≥几百毫安)或需要高功耗承受,建议改用更大封装或功率型 SCR;
  • 对于需要低触发电流与紧凑空间的控制与脉冲开关场合,MCR100-6 在合适的热管理和浪涌保护下是性价比较高的选择。

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
