BSS138-TP 产品概述

概述

BSS138-TP 是一款高性能的 N 沟道金属氧化物半导体场效应管(MOSFET),专为低功耗电路设计。其典型参数包括最大漏源电压为 50V 和连续漏极电流 220mA,使其适合于多种低功耗应用场景。该器件采用 SOT-23 封装,体积小巧,非常适合于需要高密度布局的现代电子产品中。

主要特性

  • 工作电压与电流: BSS138-TP 的漏源电压 (Vdss) 达到 50V,足够用于多种中等电压的应用。同时,最大连续漏极电流为 220mA(在 25°C 时),能够应对一般负载需求。

  • 阈值电压: 栅源极阈值电压 (Vgs(th)) 为 1.5V @ 1mA,表明该 MOSFET 可在较低的栅电压下开始导通,适合驱动各种低压电路,特别是在逻辑电平信号下表现良好。

  • 导通电阻: 在驱动电压为 10V 时,最大漏源导通电阻 (Rds(on)) 达到 3.5Ω @ 220mA。这一低导通电阻有效降低了功率损耗并增加了效率,对于需要高效能传输的应用,尤其重要。

  • 功率耗散: BSS138-TP 的最大功率耗散为 350mW(在 25°C 环境下)。合理的功率耗散能力使得该器件能在更高负载和温度环境下安全运行。

  • 工作温度范围: 该元件的工作温度范围广,支持 -55°C 到 150°C 的温度范围,能够适应极端环境。在高温或低温的工业应用中表现优秀。

  • 封装与安装类型: BSS138-TP 采用 SOT-23 表面贴装封装,满足现代电子产品对空间紧凑和高集成度的要求。该封装设计支持自动化生产线,有助于提高生产效率。

应用领域

BSS138-TP 可广泛应用于以下领域:

  1. 开关电源:基于其快速开关特性,能够用于开关电路中的开关管。
  2. 信号调节:适用于模拟和数字信号处理电路,之所以如此,是因为其较低的输入电容(Ciss,最大值为 60pF @ 25V)能够确保快速响应。
  3. LED 驱动:能够作为 LED 照明电路的开关元件,提供高效且稳定的电源管理。
  4. 低功耗微控制器接口:适合微控制器的 GPIO 引脚驱动,能够通过较低的栅电压控制较大的负载。
  5. 电池管理系统:在电池管理中用于连接和断开电池,以延长电池使用寿命。

设计注意事项

在使用 BSS138-TP 时,设计师应注意以下几点:

  • 对于功率损耗和散热,应根据实际使用环境评估 MOSFET 的工作条件,以避免超温。
  • 在实际电路设计中,确保驱动电压 (Vgs) 切合使用场合,以实现最佳的电流控制和开关性能。
  • 由于其导通电阻与工作温度有关,需避免长期在高温环境下运行,以保障期望的电气性能。

总结

总体而言,BSS138-TP 是一款可靠且高效的 N 沟道 MOSFET,适合多种低功耗应用。凭借其良好的电气特性和可靠性,BSS138-TP 成为设计师在选择开关元件时的理想选择。无论是在消费电子、工业控制还是汽车电子中,BSS138-TP 能得到良好的应用表现。

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
