WSD30L68DN33 产品概述

WSD30L68DN33 是 WINSOK(微硕)推出的一款高性能沟槽 P 沟道 MOSFET,封装为 DFN-8 (3×3),针对高密度电源与同步降压转换器等场景进行了优化。器件同时满足 RoHS 与绿色产品要求,并通过 100% 全功能可靠性检验。

一、主要规格概览

  • 类型:P 沟道 MOSFET
  • 漏源电压(Vdss):30 V
  • 连续漏极电流(Id):68 A
  • 导通电阻(RDS(on)):5.8 mΩ(在 10 V 驱动电压下典型测定)
  • 栅极电荷量(Qg):60 nC(@10 V)
  • 输入电容(Ciss):3.415 nF
  • 输出电容(Coss):245 pF
  • 反向传输电容(Crss/Crss):131 pF
  • 功率耗散(Pd):69 W
  • 阈值电压(Vgs(th)):约 1.3 V
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 包装:DFN-8 (3×3)

二、产品亮点

  • 低导通电阻与高电流能力:5.8 mΩ 的低 RDS(on) 与 68 A 的连续电流能力,可在高电流、低压差条件下显著降低导通损耗。
  • 平衡的开关特性:60 nC 的总栅极电荷在保证低导通损耗的同时,兼顾了开关损耗与驱动能耗之间的平衡,适合中高频开关应用。
  • 完整电容参数指示:Ciss/Coss/Crss 数据完整,便于工程师进行开关损耗、Miller 效应与电压应力评估。
  • 可靠性与环保:符合 RoHS、绿色产品标准,且经过 100% 全功能可靠性认证,适合工业与消费级长期供货需求。

三、典型应用场景

  • 同步降压转换器(尤其在需要 P 沟道特性的高边开关方案中)
  • 电源管理开关(负载开关、反向保护、理想二极管替代)
  • 电池供电系统与便携设备电源路径控制
  • 工业控制与汽车电子(符合温度与可靠性要求的前提下)

四、工程建议与注意事项

  • 驱动电压:器件参数 RDS(on) 与 Qg 均以 10 V 驱动条件标注,实际应用中请按目标电路的最大 Vgs 范围设定驱动策略;P 沟道在开启时需将栅极相对于源极施加足够负向电压。
  • 热管理:虽然额定 Pd 为 69 W,但 DFN-8 小封装对 PCB 散热依赖较大。建议使用大面积散热铜箔、过孔热通和底部焊盘以保证热阻最低化。
  • 开关设计:较大的 Ciss 与中等 Qg 意味着在高频应用中需关注驱动器能力与开关损耗,必要时优化死区时间与采用合适的驱动电路以减少开关交越损耗。
  • 抗干扰与保护:在高速切换场景下注意 Miller 效应(Crss)引发的误触发,必要时增加栅极电阻、RC 缓冲或驱动器带 Miller 抑制功能;同时建议电路中加入适当的浪涌与过流保护。

五、封装与可靠性

DFN-8 (3×3) 封装有利于器件在高密度板级设计中的布局,适合对体积与散热有双重要求的应用。微硕对器件进行了全面的可靠性测试,适合工业级长期供应和可靠性敏感场合。

总结:WSD30L68DN33 在低导通损耗、高电流能力与完整电容参数之间取得了良好平衡,适合需要紧凑封装与良好开关性能的电源管理与高边开关应用。对热设计与驱动策略的合理优化能够最大化其性能优势。

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
