2SC1815 产品概述
一、主要参数
2SC1815 是一款由 GOODWORK(固得沃克) 推出的低功耗 NPN 小信号三极管，封装为 SOT-23，适合表面贴装应用。主要电气参数包括：集电极电流 Ic = 150 mA，集—射极击穿电压 Vceo = 50 V，耗散功率 Pd = 200 mW，直流电流增益 hFE = 400（测量条件 2 mA，6 V），特征频率 fT = 80 MHz，集电极截止电流 Icbo = 100 nA，饱和电压 VCE(sat) ≈ 250 mV，允许结温范围 Tj = -55 ℃ ~ +150 ℃。
二、主要特性
该器件具有以下显著特性：
- 高增益：在低电流工作点（2 mA）下 hFE 高达 400，便于实现小电流驱动及增益匹配。
- 中等频率响应：fT = 80 MHz，适用于音频到中频带宽的放大与开关应用。
- 低饱和压降：VCE(sat) 约 250 mV，可降低开关损耗，提高效率。
- 低漏电：Icbo 典型值 100 nA，有利于低功耗与高阻态稳定性。
- SOT-23 封装便于自动贴装及空间受限电路设计。
三、典型应用
- 小信号放大：前置放大、音频放大、信号放大器。
- 开关电路：低电流驱动开关、逻辑接口电平转换。
- 通信与振荡电路：中频放大、振荡器与本振缓冲（受 fT 限制）。
- 便携设备与传感器：要求低功耗、高增益的小型化电路。
四、封装与引脚说明
SOT-23 的紧凑封装适配自动贴装生产。引脚排列请参照厂方封装图纸，常见引脚定义为：B（基极）、C（集电极）、E（发射极）。在电路设计时，应注意引脚热阻与散热路径，尽量通过 PCB 铜箔扩展散热以满足 Pd=200 mW 的功耗散热要求。
五、设计与使用建议
- 工作点设定：若需维持高 hFE，应在 1–5 mA 区间选择偏流，并校正温度漂移。
- 散热管理：SOT-23 封装散热受限，连续耗散接近标称 Pd 时建议增加 PCB 散热面积或采用短脉冲工作模式。
- ESD 与可靠性：在贴装与测试环节注意静电防护，工作环境避免超出标定结温范围，焊接时遵循厂方的温度曲线以保证长期可靠性。
- 替代与匹配：在需更高功率或更高频率时，可选用功率或高 fT 器件；在电路调试阶段可根据增益和偏流替换相近型号以优化性能。
综上，GOODWORK 2SC1815（SOT-23）凭借高增益、低饱和压和小型封装，适合便携与空间受限的低功耗放大与开关电路，是小信号设计中的实用元件。

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.
