BSS138-TP-ES 产品概述

一、产品简介

BSS138-TP-ES 是静芯微(ElecSuper)出品的一款小功率 N 沟增强型 MOSFET,采用 SOT-23 封装,面向低功耗开关和信号级电平控制场景。器件额定 Vdss=60V、连续漏极电流 Id=400mA,适用于需要较高耐压但电流不大的应用。器件工作温度范围宽,-55℃ 至 +150℃,适合多种工业与消费类电子环境。

二、主要参数

  • 类型:N 沟道 MOSFET(增强型)
  • 漏源电压 Vdss:60V
  • 连续漏极电流 Id:400mA
  • 导通电阻 RDS(on):1.5Ω @ Vgs=10V
  • 耗散功率 Pd:417mW(环境与 PCB 散热相关需查阅实际降额曲线)
  • 阈值电压 Vgs(th):1V @ Id=250µA
  • 栅极电荷量 Qg:650pC @ Vgs=4.5V
  • 输入电容 Ciss:25pF;反向传输电容 Crss:2.2pF;输出电容 Coss:9.7pF
  • 工作温度:-55℃ ~ +150℃
  • 封装:SOT-23;单只包装,数量:1

三、性能特点

  • 高耐压:60V 额定耐压使其在 24V/36V 及更高工况中仍有余量,适合车载辅助电路与中低压开关。
  • 逻辑门控兼容:阈值电压约 1V,易被低电平驱动检测到,但标称 RDS(on) 测试为 Vgs=10V 条件下,若使用低电压驱动(如 3.3V/5V),导通电阻会显著增大。
  • 小尺寸封装:SOT-23 占板面积小,便于高密度 PCB 布局。
  • 开关特性提示:标称栅极电荷量较大(Qg=650pC),在高频开关时需要注意驱动能力与开关损耗;Ciss、Coss 与 Crss 的典型值有助于评估驱动与稳定性。

四、典型应用

  • 低电流开关与功率管理:小型继电器或继电器驱动、负载断电控制。
  • 电平移位与接口保护:作为电平换挡或上拉/下拉开关元件。
  • 便携式与消费电子:电源路径控制、待机电源切换。
  • 工业控制与传感器前端:在耐压与散热满足时用于信号隔离或驱动小负载。

五、封装与引脚定义

  • 封装:SOT-23(小型三引脚)
  • 常见引脚排列(请参考最终器件数据手册以校准):
    • 引脚1:G(栅极)
    • 引脚2:D(漏极)
    • 引脚3:S(源极)
  • PCB 布局建议:尽量加大漏极与源极附近的铜箔,利于散热并降低接触电阻。

六、热与可靠性建议

  • 耗散功率 Pd=417mW 为器件在参考环境与焊盘条件下的额定值,实际使用中应随环境温度上升按热阻曲线降额。SOT-23 封装散热有限,高占空比或持续导通时建议扩大铜箔散热或降低载流。
  • ESD 防护:栅极对静电敏感,建议在生产与装配过程中做好静电防护,必要时在 PCB 上增加 RC 缓冲或 TVS 保护。

七、选型与使用注意事项

  • 若电路需在较低 Vgs(3.3V 或 5V)驱动并承载较大电流,需评估实际 RDS(on) 增大带来的功耗与发热,必要时选择低 RDS(on) 的逻辑级 MOSFET。
  • 高频开关场合需注意 Qg 较大带来的驱动损耗,可能要求专用栅极驱动器或缓冲级。
  • 在设计前请参考 ElecSuper(静芯微)官方完整数据手册获取详细电气特性曲线、降额图和典型应用电路,以确保最终应用的可靠性与性能。

总体来看,BSS138-TP-ES 为一款耐压高、封装小巧的 N 沟道 MOSFET,适合耐压优先且电流需求不大的开关与控制场景。正确的栅极驱动和 PCB 散热设计是发挥其性能的关键。

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
