FDMS86200-VB 产品概述

一、概述

FDMS86200-VB 是微碧半导体(VBsemi)推出的一款高压单极 N 沟道 MOSFET,采用 Trench 制程,晶圆来源为台积电,封装由长电科技完成(DFN-8,5×6 mm)。器件面向需要同时兼顾高耐压与低导通损耗的中小功率开关场合,适用于轻型电动车、智能家居、医疗设备及 LED 照明等领域。

二、主要参数

  • 类型:N 沟道 MOSFET(单个)
  • 漏源电压 Vdss:150 V
  • 连续漏极电流 Id:53.7 A
  • 导通电阻 RDS(on):15.8 mΩ @ Vgs=10 V;18.8 mΩ @ Vgs=7.5 V
  • 耗散功率 Pd:104 W(器件额定,实际依 PCB 散热而定)
  • 阈值电压 Vgs(th):约 2 ~ 4 V(典型 2 V)
  • 栅极电荷 Qg:22.8 nC @ 7.5 V;31.3 nC @ 10 V
  • 输入电容 Ciss:1.286 nF;输出电容 Coss:327 pF;反向传输电容 Crss:28 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:DFN-8(5×6 mm)

三、关键特性与优势

  • 高耐压与较低 RDS(on):150 V 耐压满足中压边缘应用,10 V 驱动下 15.8 mΩ 的低导通电阻有利于降低导通损耗与发热。
  • Trench 制程优势:改进的沟槽结构带来更低的导通电阻和更优的 SOA(安全工作区)特性。
  • 适应高温工作:器件额定温度上限 150 ℃,适合热环境下的应用,但需配合合适的散热方案。
  • 封装小型化:DFN-8(5×6)利于高密度 PCB 布局,并可通过中央散热垫实现良好热流路径。

四、典型应用场景

  • 轻型电动车驱动与电源管理(中低功率逆变与 DC‑DC 变换)
  • 智能家居电源与电机驱动模块
  • 医疗设备中的高可靠性开关电源与电机驱动
  • LED 恒流驱动与功率级开关控制

五、封装与散热建议

DFN-8(5×6) 封装要求良好的 PCB 散热设计:建议在 PCB 下方设置大面积的接地/电源铺铜并配合过孔(thermal vias)将热量传导至内层或底层散热层。器件额定 Pd 为 104 W,但实际可用耗散能力受 PCB 散热和环境温度限制,应进行热仿真与实测,按需做功率退让。

六、设计与使用建议

  • 驱动电压选择:10 V 驱动下 RDS(on) 最优,但 Qg 较高(31.3 nC @10 V),对驱动器峰值电流和开关损耗影响较大。驱动器需具备足够电流能力与控制栅阻以平衡开关速度与 EMI。
  • 开关损耗与电容:Ciss、Coss 与 Crss 指示了开关时的能量存储与回收特性;在高频应用中,Coss 与 Qg 会显著影响开关损耗,必要时采用软开关拓扑或能量回收电路。
  • 保护与可靠性:考虑体二极管恢复特性与过流保护;在高应力场合加入合适的 TVS、RC 抑制或缓冲网络以抑制电压尖峰。
  • 布局要点:低阻抗的电源回路、最短的漏—源回路路径和紧凑的门极驱动回路可以降低寄生电感,减少振铃与发热。

七、结论

FDMS86200-VB 在 150 V 等级中提供了兼顾低导通阻抗与较高电流能力的解决方案,适合多种中低频率功率开关应用。设计时需重点考虑栅极驱动能量、开关损耗及 PCB 散热布局,以充分发挥该器件在效率与可靠性方面的优势。若需进一步的电气特性曲线、封装图或参考电路,可联系供应商获取完整 Datasheet。

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
