FDC6333C 产品概述

一、简介

FDC6333C 是 TECH PUBLIC(台舟电子)推出的一款增强型双MOSFET(N沟道 + P沟道),采用 SOT-23-6 小封装,额定漏源电压 Vdss 为 30V,针对便携电源、充电设备和电源管理系统等要求高效率与小体积的应用进行了优化设计。器件兼顾低导通电阻与快速开关特性,适合在受限空间中实现高效功率转换与控制。

二、主要规格参数

  • 漏源电压(Vdss):30V(N沟道 / P沟道)
  • 连续漏极电流(Id):4A(N) / 3A(P)
  • 导通电阻(RDS(on)):30mΩ @ Vgs=10V(N) / 45mΩ @ Vgs=10V(P)
  • 阈值电压(Vgs(th)):1.6V(N) / 1.5V(P)
  • 总栅极电荷量(Qg):5nC @ Vgs=10V(双通道标称)
  • 输入电容(Ciss):199pF(N) / 210pF(P)
  • 反向传输电容(Crss):23pF(N) / 28pF(P)
  • 输出电容(Coss):35pF(N) / 47pF(P)
  • 工作温度范围:-55℃ ~ +150℃
  • 封装:SOT-23-6

三、主要特性与优势

  • 低导通损耗:N沟道 30mΩ、P沟道 45mΩ(均在 Vgs=10V 时测得),适合低压高电流路径,降低导通功耗,提升效率。
  • 快速开关:较小的总栅极电荷(Qg≈5nC)与适度的 Ciss/Coss,保证较低的开关损耗与较快的开关响应,利于高频率电源设计。
  • 小型封装高集成度:SOT-23-6 一体化 N/P 对,便于占板面积受限的移动设备或模块化电源解决方案。
  • 宽温度适应性:-55℃ 至 +150℃ 的工作温度范围,适用于工业级与消费电子混合应用场景。

四、典型应用场景

  • 移动设备与充电器中的同步整流或高/低侧开关
  • 电池管理与电源路径选择(load switch、reverse blocking)
  • DC-DC 升降压转换器中作为半桥或互补开关使用
  • 电源管理模块、节能照明及其他需紧凑封装的功率开关场合

五、封装与热特性

FDC6333C 采用 SOT-23-6 小封装,方便表贴组装与高密度 PCB 设计。尽管封装体积小,但在布局时应注意热散布:通过在 PCB 下方和附近增加铜箔面积、必要时添加散热过孔,可显著降低结温并提升连续导流能力。

六、使用建议与注意事项

  • 推荐栅极驱动:为发挥最低 RDS(on),建议 Vgs 驱动至 10V;若系统为低压驱动(如 5V),请评估实际 RDS(on) 与热耗。
  • 开关布局:尽量缩短栅极、漏极与源极之间的互连长度,加入门极电阻以抑制振铃并控制上升/下降斜率。
  • 保护与可靠性:注意器件 Vdss 上限为 30V,避免过压状况;在感性负载场合加入合适的续流或吸收网络以防止瞬态破坏。
  • 并联与散热:若需要更大电流,建议在热与电路设计上慎重评估并联方案,确保均流与散热充足。

FDC6333C 凭借小体积、低损耗与快速开关特性,为便携电源与电源管理系统提供高效、稳定的解决方案。根据具体应用场景合理驱动与布局,可显著提升系统能效与可靠性。

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
