HKTG50N03 N沟道MOSFET产品概述

一、核心参数概览

HKTG50N03是合科泰(Hottech)推出的N沟道增强型MOSFET,核心参数精准匹配低压大电流应用需求,关键指标如下:

  • 耐压能力:漏源击穿电压(Vdss)30V,覆盖12V/24V等主流低压系统;
  • 电流承载:连续漏极电流(Id)50A(25℃),可稳定支撑大负载电流;
  • 导通损耗:导通电阻(RDS(on))9.3mΩ(Vgs=4.5V,Id=20A),低损耗优势显著;
  • 驱动兼容性:阈值电压(Vgs(th))1V,兼容3.3V/5V低栅极驱动;
  • 开关特性:栅极总电荷(Qg)9.8nC(Vgs=10V),输入电容(Ciss)940pF,开关速度快;
  • 可靠性范围:工作温度-55℃~+150℃,满足工业级环境要求;
  • 封装与功耗:PDFN5x6封装,最大耗散功率(Pd)37W(25℃)。

二、关键性能优势

1. 低导通损耗与高电流密度

9.3mΩ的导通电阻在4.5V栅极驱动下即可实现,当负载电流20A时,导通损耗仅约3.7W,大幅降低系统发热。同时50A连续电流在5mm×6mm紧凑封装下,实现了高电流密度,适配高密度PCB设计。

2. 宽栅极驱动兼容性

1V的阈值电压确保3.3V/5V低驱动电压即可稳定导通,无需额外升压电路,简化了驱动电路设计,尤其适合嵌入式系统、电池供电设备等场景。

3. 快速开关特性

低栅极电荷(9.8nC)和输入电容(940pF)优化了开关损耗,可支持kHz级高频应用(如DC-DC同步整流),提升系统效率至95%以上。

4. 工业级可靠性

-55℃~+150℃的宽温范围,覆盖户外、工业控制等恶劣环境;PDFN5x6封装抗振动性能优异,适合高可靠性场景。

三、封装与散热设计

HKTG50N03采用PDFN5x6表面贴装封装,具有以下特点:

  • 紧凑体积:尺寸5mm×6mm×0.8mm,适配空间受限的PCB(如笔记本电脑、小型电源模块);
  • 低散热热阻:封装热阻(Rth(j-a))约10℃/W,37W耗散功率无需额外散热片即可满足多数应用;若负载电流较大,可通过增加PCB铜箔面积优化散热;
  • 抗干扰性:表面贴装减少引线电感,提升高频开关场景的抗干扰能力。

四、典型应用场景

HKTG50N03的参数特性使其广泛适用于低压大电流场景:

  1. 低压DC-DC转换:12V转5V、24V转12V同步整流电路,低损耗提升转换效率;
  2. 电池管理系统(BMS):电池充放电回路开关控制,50A电流满足多串电池组需求;
  3. 小型电机驱动:直流风扇、无刷电机驱动,快速开关提升控制精度;
  4. 负载开关:笔记本、平板电源开关,低导通损耗降低待机功耗;
  5. 工业控制:替代继电器实现无触点开关,宽温适应工业现场环境。

五、应用注意事项

  1. 驱动电压:建议Vgs≥4.5V以保证低导通电阻,避免超过器件最大额定值(参考 datasheet);
  2. 静电防护:MOSFET栅极易受静电损坏,组装需防静电措施(接地工作台、手环);
  3. 散热优化:高负载时需增加PCB铜箔面积,必要时加装小型散热片;
  4. 过流保护:配合过流保护电路,避免瞬间大电流损坏器件。

HKTG50N03凭借低损耗、高电流、宽驱动等优势,成为低压大电流应用的高性价比选择,适配消费电子、工业控制等多领域需求。

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
