BSC050NE2LSATMA1 产品概述

一、器件简介

BSC050NE2LSATMA1 是英飞凌(Infineon)出品的一款 N 沟道功率 MOSFET,适用于 12V 级电源与高速开关应用。主要电气参数包括:漏源电压 Vdss = 25V,连续漏极电流 Id = 49A,导通电阻 RDS(on) = 5mΩ(Vgs = 10V),耗散功率 Pd = 28W。门极阈值 Vgs(th) = 2V(250µA),总栅极电荷 Qg = 10.4nC(Vgs = 10V),输入电容 Ciss ≈ 1.011nF,反向传输电容 Crss ≈ 35pF,输出电容 Coss ≈ 426pF。工作结温范围 -55℃ 到 +150℃,封装为 TDSON-8。

二、性能亮点

  • 低导通电阻(5mΩ@10V),在导通状态下损耗小,适合高电流路径;
  • 较高的连续漏极电流(49A),能满足短时大电流要求;
  • 适度的栅极电荷(10.4nC),在保持低导通电阻的同时,开关损耗可控;
  • 宽工作温度与较高的功率耗散(28W),适合苛刻环境与紧凑版面散热设计;
  • TDSON-8 小型封装,有利于轻量化与高密度 PCB 布局。

三、典型应用场景

  • 同步整流与降压 DC-DC 转换器(尤其 12V 输入、低压输出场合);
  • 电源管理开关、负载开关与逆变前端开关;
  • 电机驱动与电池保护电路(需配合热设计与 SOA 校核);
  • 通信设备与消费电子的功率级控制。

四、驱动与开关设计要点

  • 推荐驱动电压 10V 以达到标称 RDS(on);若采用逻辑电平驱动需核对 RDS(on) 随 Vgs 的上升;
  • Qg = 10.4nC,对应的驱动能量与驱动电路尺寸需按开关频率评估:开关损耗近似与 Qg × Vdrive × fs 成正比;
  • Crss(35pF)对 Miller 效应影响有限,但在快速边沿下仍需注意布局与回流路径,减少寄生电感以避免过冲与振铃。

五、热管理与封装注意

  • 虽然 Pd = 28W,但 TDSON-8 封装的热阻需通过 PCB 铜箔与过孔扩散散热;建议在功率层使用大面积散热铺铜并优化回流路径;
  • 注意 RDS(on) 随结温上升而增加,长时高电流工作需留裕量并评估结温;最大结温 150℃,工作时尽量控制在安全余量内;
  • 焊接与回流按厂方推荐工艺进行,避免过高温度与机械应力影响可靠性。

六、选型与应用建议

  • 若目标为 12V 系统中低压高电流开关或同步整流,BSC050NE2LSATMA1 为性价比较高的选择;若需更低 RDS(on) 或更低 Qg,可在英飞凌系列中比较同电压等级的其他型号;
  • 在驱动器设计中权衡导通损耗与开关损耗,合理选择驱动电压与开关频率,并做好 PCB 热与寄生抑制设计;
  • 对于感性负载,需核对器件的峰值耐受能力与单脉冲能量(SOA、avalanche)以确保可靠性。

总结:BSC050NE2LSATMA1 以低 RDS(on)、较高电流承载能力与适中栅极电荷为特点,适合 12V 级电源转换与高密度功率设计;成功应用依赖于合理的驱动、布局与散热设计。

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
