BSS138LT3G 产品概述

概览

BSS138LT3G 是一种高性能、低功耗的 N 通道 MOSFET（场效应管），由安森美（ON Semiconductor）制造。该器件专为需要较高开关速度和良好电流控制的应用场景设计，广泛应用于智能手机、平板电脑、便携式设备、以及其他需要节能高效性能的电子产品。其采用 SOT-23-3（TO-236）封装，适合表面贴装技术（SMT），便于大规模生产和集成。

关键电气参数

  1. 漏源电压 (Vdss): BSS138LT3G 具有最大 50V 的漏源电压，适用于多种电源管理和信号开关应用。高漏源电压确保在各种工作条件下的可靠性。

  2. 连续漏极电流 (Id): 器件可以承受最大 200mA 的连续漏极电流（在 25°C 时），确保其在高负荷条件下依旧稳定工作。

  3. 导通电阻 (Rds On): 在 Vgs 为 5V 的条件下，BSS138LT3G 的最大导通电阻为 3.5Ω，这在一定程度上降低了功率损耗，提高了效率。

  4. 阈值电压 (Vgs(th)): 最大阈值电压为 1.5V@1mA，有利于在低电压信号下实现快速开关，从而提升设计灵活性。

  5. 输入电容 (Ciss): 在 25V 下，其输入电容的最大值为 50pF，这使得器件在高频应用中具有良好的性能，能够快速响应输入信号。

  6. 功率耗散 (Pd): 在 25°C 的环境下，BSS138LT3G 的最大功率耗散达 225mW，适合在要求较小功率损耗的应用场景中使用。

工作条件与特性

BSS138LT3G 的工作温度范围广，能够在 -55°C 至 +150°C 的环境中稳定运行。这使得该 MOSFET 在极端环境下的電子应用中表现出色，如汽车电子、航空航天设备和工业控制系统。

该器件采用表面贴装型设计，使其在电路板的空间利用上达到最优化，非常适合现代小型化、高密度布局的趋势。此外，封装选用 SOT-23-3（TO-236）形式，使设备的散热效率和生产效率达到较高水平。

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
