YJL2302B 产品概述
一、产品简介
YJL2302B 是扬杰（YANGJIE）出品的一款小封装 N 沟道场效应管（MOSFET），封装为 SOT-23-3L，单只器件适用于低压、低功耗开关和功率管理场景。器件额定漏源耐压为 20V，连续漏极电流 3A，器件功耗 Pd 为 700mW，适合便携式和空间受限的电路设计。
二、主要性能参数
- 类型：N 沟道 MOSFET（单只）
- 漏源电压 Vdss：20V
- 连续漏极电流 Id：3A（需注意散热限制）
- 导通电阻 RDS(on)：80mΩ @ Vgs=2.5V，I=2A
- 阈值电压 Vgs(th)：780mV
- 总栅极电荷 Qg：2.9nC @ Vgs=4.5V
- 输入电容 Ciss：280pF @ 10V；输出电容 Coss：46pF；反向传输电容 Crss：29pF @ 10V
- 封装：SOT-23-3L
- 品牌：YANGJIE（扬杰）
三、器件特点与优势
- 低导通电阻：在仅 2.5V 栅压下 RDS(on)=80mΩ，适合 1S 电池或低压逻辑直接驱动的负载开关。
- 低栅极电荷：Qg=2.9nC（4.5V）使其在开关频率不太高的 PWM 或 DC-DC 变换器中具有较低驱动能耗和较快开关速度。
- 紧凑封装：SOT-23 体积小，便于高密度 PCB 布局和空间受限应用。
四、典型应用场景
- 电池供电设备的高侧/低侧开关（需注意耐压）
- 便携式充电管理与电源路径切换
- 低压 DC-DC 降压转换器输出开关或同步整流（取决于系统热设计）
- 反向电流防护、负载开关、音频/传感器电源开断
五、使用建议与热管理
- 虽然 Id 标称 3A，但封装功耗 Pd=700mW 限制了长期大电流能力。例：2A 导通时器件自身发热约 I^2·R ≈0.32W，需通过合理铜箔面积和散热设计保证结温在安全范围内。
- 建议采用较大焊盘、短走线及必要的热过孔以提升散热。
- 栅极驱动采用 4.5V 或更高驱动电压可获得更低 RDS(on)，但请参照器件手册确认最大 Vgs 限制。
- 高频开关时关注 Coss/Crss 对电压和回流的影响，适当缓冲和阻尼以降低电磁干扰。
六、封装与选型注意事项
购买与布局前请查阅完整器件手册确认引脚定义、最大额定值及典型参数曲线；在并联或替换同类器件时务必核对 RDS(on)、Qg 和热阻参数，确保可靠性。若需更高电流或更低导阻，应考虑更大封装或增强型器件。
Request for quote
Send RFQ
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.
