CES2305-VB 产品概述
一、概述
CES2305-VB 是微碧半导体（VBsemi）推出的一款 P 沟道场效应管，采用 SOT-23（TO-236）小巧封装，面向便携式电源管理和高侧开关场合。器件在 20V 漏源耐压下提供 4A 连续漏极电流能力，适合空间受限但需可靠开关控制的小功率电路。
二、主要参数
- 类型：P 沟道 MOSFET
- 漏源电压 Vdss：20 V
- 连续漏极电流 Id：4 A
- 导通电阻 RDS(on)：60 mΩ @ Vgs = 10 V
- 阈值电压 Vgs(th)：1.5 V @ Id = 250 μA
- 总栅极电荷 Qg：10 nC @ Vgs = 4.5 V
- 输入电容 Ciss：835 pF；反向传输电容 Crss：155 pF；输出电容 Coss：180 pF
- 功耗 Pd：1.6 W
- 工作温度范围：-55 ℃ ~ +150 ℃
- 封装：SOT-23（TO-236）
三、特性与优势
- 小封装高集成：SOT-23 封装适用于空间受限的消费电子和便携设备。
- 良好开关性能：较低的总栅极电荷（10 nC @4.5V）便于用较小驱动能量实现快速切换，适配 4.5V 驱动电平。
- 中等导通电阻：60 mΩ 在 10V 驱动下能在保持较低功耗的同时支持数安培负载。
- 宽温度范围：-55 ℃ 至 +150 ℃，适合工业级温度需求。
四、典型应用
- 高侧负载开关与电源切换（电池管理、便携设备开关）
- 反接/倒置保护电路
- DC-DC 升降压模块中的高侧功率开关（低至中功率级）
- 小电流电机驱动、背光驱动与功率分配开关
五、设计与热管理建议
- 在 SOT-23 封装和 Pd = 1.6 W 的限制下，注意 PCB 散热布局：增大铜箔面积并使用散热焊盘，避免长期大电流下过热。
- 选用合适的栅极电阻以控制开关过渡与振荡，同时根据驱动器能力调整以兼顾开关损耗与 EMI。
- 注意器件的栅源电压极限（详见完整数据手册），避免超过额定 Vgs 导致损伤。
- 在高速开关场合，考虑 Crss 对损耗与电压尖峰的影响并适当增加钳位或吸收元件。
六、封装与订购信息
- 品牌：VBsemi（微碧半导体）
- 型号：CES2305-VB
- 封装：SOT-23（TO-236）

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.
