BSS131 产品概述

一、产品简介

BSS131 是一颗高压小信号 N 通道场效应管,封装为 SOT-23,适合在对电压耐受要求较高但电流较小的场合使用。本型号由 HXY MOSFET(华轩阳电子)提供,器件在 240V 漏源耐压条件下,具备较小的输入电容与适中的门极电荷,便于实现快速开关。

二、主要参数速览

  • 类型:N 沟道 MOSFET(单只)
  • 漏源电压 Vdss:240 V
  • 连续漏极电流 Id:100 mA
  • 导通电阻 RDS(on):14 Ω @ Vgs = 10 V,Id = 0.1 A
  • 功耗 Pd:360 mW
  • 阈值电压 Vgs(th):1.8 V(典型)
  • 总门极电荷 Qg:3.1 nC @ 10 V
  • 输入电容 Ciss:77 pF @ 25 V
  • 反向传输电容 Crss:4.2 pF @ 25 V
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-23

三、性能特点与优势

  • 高耐压设计(240V),适合交流整流后高电压侧的小功率开关场合。
  • 低输入电容(Ciss 77 pF)与中等门极电荷(3.1 nC),便于快速驱动且对驱动功率要求较低。
  • 在 10 V 门极驱动时可获得标称的 RDS(on),适合使用专用驱动或较高电平逻辑驱动场合。
  • SOT-23 小封装,适合体积受限的 PCB 布局与批量自动贴装。

四、典型应用场景

  • 小电流高压开关:例如高压偏置切换、仪表高压通断控制。
  • 启动/保护电路:开机限流、软启动控制、反向保护等。
  • 驱动与隔离:作为电位差大但电流要求不高的隔离开关或电平转换器件。
  • 消费类与便携设备内部高压电路中的开关元件。

五、设计与使用建议

  • 驱动电压:为了达到资料所示的导通电阻,建议门极驱动到 10 V;若仅由 5 V 驱动,请核查在低 Vgs 下的 RDS(on) 与功耗是否满足要求。
  • 热管理:器件功耗 Pd 为 360 mW,SOT-23 封装热阻较大,长时间工作时需注意 PCB 散热、增加铜箔面积或使用热孔过孔以降低结温。
  • 驱动与保护:建议在门极串联小电阻以抑制振荡,必要时并联 TVS 或 RC 抑制器以应对感性负载产生的尖峰电压。
  • 布局:尽量缩短高电流回路的走线与门极驱动回路,减小寄生电感与电容对开关性能的影响。
  • 最大 Vgs:本文档未给出 Vgs 最大额定值,设计时请参考器件完整数据手册并确保不超过其最大门源电压。

六、选型与替代考虑

BSS131 更适合“高压、低电流、小功耗”的应用;若系统需要更低的导通损耗或更大持续电流,应选择 RDS(on) 更小、Pd 更高且封装散热能力更强的器件(例如 SOT-223、SO-8 等封装的高压 MOSFET)。在选择替代器件时,重点核对 Vdss、RDS(on)(在同一 Vgs 下)、Qg 及 Ciss 等参数以保证兼容性。

七、包装与采购信息

  • 单位:1 只(SOT-23 封装)
  • 品牌:HXY MOSFET(华轩阳电子)
    采购时请确认器件批次与完整原厂数据手册,校核寄生参数、极限值与测试条件以满足实际应用需求。

总结:BSS131 以其高耐压、小输入容与中等门极电荷的特点,适合多种需要高电压耐受但电流不大的电子开关场合。设计时应重视门极驱动与散热管理,以发挥器件最佳性能。

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
