2N3904 产品概述
一、核心特性
GOODWORK(固得沃克) 2N3904 是一颗通用型 NPN 晶体管，适合小信号放大、开关和振荡等应用。器件以 SOT-23 封装提供，单片数量为1只，工作温度范围宽 (-55℃ ~ +150℃)，具有良好的频率响应与线性特性，便于表面贴装于现代电子设备。
二、主要电气参数
- 晶体管类型：NPN
- 集电极电流 Ic：200 mA（最大）
- 集射极击穿电压 Vceo：40 V
- 耗散功率 Pd（封装限制）：200 mW
- 直流电流增益 hFE：100（典型）
- 特征频率 fT：300 MHz
- 集电极截止电流 Icbo：100 nA
- 集射极饱和电压 VCE(sat)：300 mV（在规定偏流下）
- 射基极击穿电压 Vebo：6 V
三、典型应用场景
- 小信号放大器：用于音频前级、传感器信号调理与低功率放大器。
- 开关电路：适合驱动小负载、逻辑接口和指示灯控制。
- 振荡与高频电路：300 MHz 的 fT 允许在较高频段用于振荡器或射频前端的低噪声放大。
- 通用原型与教学：因参数均衡，常作为实验与教学参考器件。
四、封装与热管理
SOT-23 封装易于表贴并节省空间，但热阻较大，Pd 受限为 200 mW，须在 PCB 设计时注意散热：
- 增加散热铜箔面积并连接到地平面；
- 避免长时间在最大 Ic 与高 Vce 条件下工作；
- 在高频或连续开关工况下考虑更大安全裕量。
五、设计与使用注意事项
- 在开关应用中留意 VCE(sat) ≈ 300 mV，配合驱动电流选择基极限流电阻；
- hFE 为典型 100，低电压或高温度下会变化，设计偏置时留有余量；
- Icbo 为 100 nA，适合做低泄漏应用但在高温下漏电会增大；
- Vebo=6 V，应避免基极对发射极施加过高反偏电压。
六、测试与可靠性
GOODWORK 提供符合工业级温度 (-55℃~+150℃) 的可靠性指标，建议在开发阶段进行温度循环、ESD 与长期老化测试，验证在目标应用中的稳定性。
七、采购与替代建议
该器件适用于需要 SOT-23 小封装和中等电流能力的场景。若需更高耗散或更大电流，可选封装更大或强化散热的型号；如需更高增益或更低 VCE(sat)，可选专用开关/放大晶体管系列。购买时请确认品牌 GOODWORK(固得沃克) 与封装 SOT-23，以保证参数一致性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
