MMBT3904,215 产品概述

一、概述

MMBT3904,215 是一款高性能 NPN 型三极管，封装采用表面贴装型 (SMD) 的 TO-236AB (SOT-23)，适用于小型化电子设备的设计与应用。其最大集电极电流 (Ic) 为 200mA，具有良好的工作温度范围 (TJ) 最高可达 150°C，特别适合在有限空间内提供可靠的出色性能。

二、基本参数

  1. 电压和电流特性:

    • 最大集电极电压 (Vceo)：40V，这使得 MMBT3904,215 可在较高电压条件下应用，适合多种电源配置。
    • 最大集电极电流 (Ic)：200mA，能够在较高负载条件下稳定工作。
    • 集电极截止电流 (ICBO)：50nA (最大值)，表明在关断状态下漏电流非常小，增强了其在低功耗应用中的表现。

  2. 功率和频率:

    • 最大功率耗散为 250mW，确保在适当的散热条件下，三极管能持续稳定工作。
    • 跃迁频率可达 300MHz，适合高速开关应用，与低功耗设计的需求相吻合。

  3. 增益特性:

    • DC 电流增益 (hFE) 最小值为 100 @ 10mA，1V，显示出其在小信号放大方面的优越性。这个增益值使得 MMBT3904 能够有效提高输入信号的幅度，使其在信号处理应用中极具价值。
    • 不同 Ib、Ic 时的 Vce 饱和压降最大值为 300mV (在 5mA 和 50mA 的测试条件下)，工艺优化，确保三极管在高效率工作时表现出较低的压降，这对电源管理至关重要。

三、应用场景

MMBT3904,215 在消费电子、通信设备及工业控制等领域有广泛应用。常见的应用包括：

  1. 开关控制: 可用于开关电源的控制电路或负载驱动电路，适配 LED 驱动、电机控制等。

  2. 信号放大: 在无线通信设备、音频设备等应用中，MMBT3904 能够作为小信号放大器，提高信号强度。

  3. 电流放大: 适合于需要电流放大的缓冲级，提供输入信号的高增益处理。

  4. 小型化产品设计: 由于其小巧的 TO-236 封装，MMBT3904 是诸多手持设备、可穿戴设备中的首选部件，充分满足现代产品对轻薄化和高性能的要求。

四、总结

总的来说，MMBT3904,215 是一款功能强大的 NPN 三极管，具备了优良的电气性能与广泛的应用范围。其高集电极电流、低能耗设计和高频响应特性，使其成为现代电子设计中不可或缺的重要元件。无论是在信号放大、开关控制，还是在新型消费电子及智能制造设备中，MMBT3904 都展示出了其独特的价值，为工程师们的设计提供了强而有力的支持。选择 MMBT3904,215，必将使您的产品在性能与效率上达到更高的标准。

Sourcing availability signal

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
