BSZ130N03LSGATMA1 产品概述

一、概述

BSZ130N03LSGATMA1 为 Infineon OptiMOS™ 系列的 N 沟功率 MOSFET,封装为 PG‑TSDSON‑8(8‑PowerTDFN),以卷带(TR)形式供应。器件额定漏源电压为 30V,25°C 时连续漏极电流为 10A(环境温度 Ta)或 35A(基板/壳温 Tc),适配中低压开关电源与负载开关应用。器件处于有源状态,适合表面贴装自动化生产。

二、主要电气参数

  • Vdss:30V,适合 12V/24V 系统的开关与整流场景。
  • Id(25°C):10A(Ta),35A(Tc)。
  • Rds(on):在 Vgs=10V、Id=20A 条件下最大值 13 mΩ;器件在 Vgs=4.5V 下也有导通特性(适用于较低驱动电压场合),但 Rds(on) 会相应增加。
  • Vgs(th):最大 2.2V(测试电流 250µA)。
  • Vgs 最大额定:±20V。
  • 栅极电荷 Qg(最大):13 nC @ 10V,属于中等栅电荷量级。
  • 输入电容 Ciss(最大):970 pF @ 15V。
  • 功率耗散:2.1 W(Ta),25 W(Tc)。
  • 工作结温 TJ:-55°C ~ 150°C。

三、性能特点与开关行为

该器件在 Vgs=10V 下具有极低的导通电阻与较高的电流承载能力,适合要求低导通损耗的同步整流及高效 DC-DC 设计。13 nC 的总栅电荷意味着驱动器需提供中等能量以实现快速切换:例如在 1 MHz 开关频率下,平均栅驱动电流约为 Qg·f ≈ 13 mA。Ciss≈970 pF 对开关边沿与 EMI 有一定影响,需在驱动与布局上做好抑制措施。

四、典型应用

  • 同步整流与点对点(Point‑of‑Load)转换器
  • 高效 DC‑DC降压模块(SMPS)
  • 电源分配开关与负载断开保护
  • 电池管理与便携设备电源路径控制
  • 小型电机驱动与逆变前端开关

五、封装与散热设计要点

TSDSON‑8(PowerTDFN)为低剖面 SMD 封装,需依靠 PCB 铜箔及焊盘为主的散热路径。设计时建议:

  • 在 PCB 底部/内层布置大面积散热铜箔并连接焊盘热通孔(via)以提高 Tc 能力;
  • 保证关键电流回路宽短,减小寄生电感;
  • 按 Infineon 的回流焊曲线进行焊接,避免超出材料温度限制;
  • 基于 Pd(Ta/Tc)差异进行热耗散与电流能力的设计与降额。

六、驱动与 PCB 布局建议

  • 为控制开关振铃与电磁干扰,可在栅极串联小阻(常见 2–20 Ω)并在栅源间并联 RC 或 TVS 做过冲保护;
  • 确保驱动信号幅值不超过 ±20V,Vgs 在 ±12V 范围通常更安全;
  • 电源旁路电容应尽可能靠近 MOSFET 的供电引脚与器件放置,以减少环路面积;
  • 对高频开关应用,考虑在源端实现短回流路径和必要的夹位二极管或 RC 缓冲以降低 dv/dt 引起的问题。

七、选型提示与结论

BSZ130N03LSGATMA1 在 30V 等级中提供了低 Rds(on) 与良好热性能的折衷,适合需要在有限 PCB 面积上实现高效率开关的场合。选型时关注驱动电压(4.5V vs 10V 的导通电阻差异)、实际工作电流与散热条件;若目标为更低导通损耗,可在保证散热的前提下以 Vgs=10V 驱动以发挥最低 Rds(on) 性能。总体而言,该器件在中低压功率管理与同步整流领域具有较高的应用价值。

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.
