BSS138W-7-F-ES 产品概述

一、产品简介

BSS138W-7-F-ES 是 ElecSuper(静芯微)推出的一款小功率 N 沟道场效应管(MOSFET),采用紧凑型 SOT-323 封装,适用于空间受限的消费电子和便携设备电路。该器件旨在提供低电压驱动下的可靠开关性能,适合开关、保护与电平移位等应用场景。

二、主要技术参数

  • 类型:N 沟道 MOSFET(单个)
  • 漏源耐压 Vdss:60 V
  • 连续漏极电流 Id:360 mA
  • 导通电阻 RDS(on):1.5 Ω @ VGS = 10 V;1.6 Ω @ VGS = 4.5 V
  • 阈值电压 VGS(th):1 V @ ID = 250 μA
  • 总栅极电荷 Qg:650 pC @ VGS = 4.5 V
  • 输入电容 Ciss:25 pF;输出电容 Coss:9.7 pF;反向传输电容 Crss:2.2 pF
  • 最大耗散功率 Pd:236 mW
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-323(超小型)

三、特性与优势

  • 小尺寸封装:SOT-323 提供极佳的板级密度,适用于手机、可穿戴设备、蓝牙模组等对空间敏感的设计。
  • 宽电压余量:60 V 漏源耐压满足多数中低压电源管理和保护电路需求。
  • 低门限与可靠开通:VGS(th) 约 1 V,便于在较低门极驱动下实现控制;在 4.5 V / 10 V 驱动下有稳定的 RDS(on) 表现。
  • 低寄生电容:Ciss、Coss 与 Crss 数值较小,有利于降低开关损耗与改善开关速度(注意 Qg 相对值)。
  • 容许较宽工作温度:-55 ℃ 至 +150 ℃,适合多环境应用。

四、典型应用

  • 低侧电源开关与负载开关
  • 电平移位与信号开关(尤其是空间受限场合)
  • 便携式电池供电设备的电源管理
  • 接口电路保护与小信号开关
  • 作为电压检测/控制电路中的开关元件

五、封装与热设计

SOT-323 封装体积小,热阻相对较高。最大耗散功率 Pd 为 236 mW(在规定测试条件下),实际应用中应注意功耗与结温上升:

  • 在连续导通或高频开关场合,应限制器件的平均功耗或采用热沉与 PCB 铜箔散热(扩大 GND 或散热垫面积)。
  • 在高占空比和高电流应用中建议选用更低 RDS(on) 或更大封装的 MOSFET 以避免过热。

六、选型与使用建议

  • 若电流接近器件额定值(360 mA)或应用长期导通,建议评估结温并适当降额使用。
  • 由于 Qg(650 pC @4.5 V)对驱动能力有一定要求,若追求快速开关,需确保驱动源能够提供足够的瞬时电流或采用驱动器件降低开关损耗。
  • 对于要求极低导通损耗的场合,应考虑 RDS(on) 更小的替代型号;本器件更适合小电流开关与信号级控制。
  • 布局上应尽量缩短源极与地的回流路径,增大散热铜箔面积以优化热性能。

七、可靠性与焊接注意事项

ElecSuper(静芯微)系列产品通常通过常规电气与可靠性测试(建议在采购时确认具体检测报告)。SOT-323 为表贴型封装,推荐遵循厂商的回流焊温度曲线与 ESD 防护措施(MOSFET 为静电敏感器件),储存与搬运时避免潮湿与静电损伤。

总结:BSS138W-7-F-ES 是一款面向空间受限、低至中等电流开关应用的 N 沟道 MOSFET,具有 60 V 耐压与小型封装优势。在合理的热设计与合适的驱动条件下,可用于多种便携与接口级电路中。若有更高开关速度或更低导通损耗的需求,可在选型阶段与器件供应方进一步确认替代型号与测试数据。

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
