JMSH1004BC 产品概述

一、主要参数

JMSH1004BC 是 JJW(捷捷微)推出的一款 100V N 沟道功率 MOSFET,封装为 TO-220。典型电气参数如下:Vdss = 100V,连续漏极电流 Id = 139A,导通电阻 RDS(on) = 3.5mΩ(Vgs = 10V),耗散功率 Pd = 156W,阈值电压 Vgs(th) = 2.7V。栅极总电荷 Qg = 57nC(@10V),输入电容 Ciss = 3.433nF,输出电容 Coss = 905pF,反向传输电容 Crss = 13pF。

二、关键特性

  • 超低 RDS(on):在 Vgs=10V 时仅 3.5mΩ,适合低导通损耗、高电流场合。
  • 低栅极电荷:Qg = 57nC,有利于减小栅极驱动能耗与开关损耗。按 E = Qg·Vgs/2 估算,10V 驱动时单次开关能量约 285nJ,若在 100kHz 切换则栅极功耗约 28.5mW。
  • 低 Miller 电容:Crss = 13pF,有助于降低米勒效应,改善开关过渡特性。
  • 100% UIS(单脉冲感应短路)与 100% Rg 测试:出厂保证单脉冲鲁棒性和栅阻一致性,提升可靠性与可复制性。
  • 环保工艺:无铅镀层、无卤并符合 RoHS 要求。

三、典型应用场景

适用于计算设备与消费电子的电源管理、工业 4.0 与通信设备的高效开关电源、以及电动工具、电动车(包括电动自行车)、机器人等领域的电机驱动与逆变器。低导通阻抗配合较高的电流能力,使其在同步整流、主开关和电机桥臂场合表现优秀。

四、驱动与热设计建议

  • 驱动电压:为达成标称 RDS(on),建议采用 10–12V 门极驱动;Vgs(th)=2.7V 表明器件在低电压下开始导通,但非严格的“5V 逻辑电平全导通”器件。
  • 驱动能力:若期望快速开关(例如 100ns 阶),所需驱动电流约 I = Qg / t ≈ 0.57A;若追求更快(20ns),则需 ~2.85A 驱动能力。根据系统切换速度与 EMI 要求,建议串联合适的门极电阻(典型 2–22Ω),以平衡开关损耗和振铃/EMI。
  • 热管理:TO-220 封装在无散热片时热阻限制较大,Pd=156W 为器件在理想散热条件下的最大耗散能力。实际应用中应配合合适散热片或 PCB 散热设计,并参考器件数据表中的 RθJA/RθJC 与 SOA 曲线进行功耗与温度评估。
  • 并联使用:低 RDS(on) 有利于并联以获取更高电流,但必须做好电流均分(小的源电阻或平衡电阻、同一温度环境、光滑的 PCB 路径)以避免热跑。

五、可靠性与封装说明

JMSH1004BC 在生产检验时执行 100% UIS 和 Rg 测试,确保器件对感性负载单脉冲事件具有良好抗性且栅极电阻一致性好。TO-220 封装便于外部散热与安装,适合中高功率场合。出于可靠性和焊接工艺考量,请参照 JJW 的器件数据手册检查最大结温、焊接工艺及封装机械尺寸。

总结:JMSH1004BC 以其极低的导通电阻和合理的开关特性,在电源管理与电机驱动等高功率应用中具有竞争力。针对具体系统,请结合实际开关频率、驱动能力与热设计进行详细的损耗与热仿真,以发挥器件最佳性能。

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
