SI2301DS-ES 产品概述

一、产品简介

SI2301DS-ES 是 ElecSuper(静芯微)推出的一款 P 沟道场效应管(P-MOSFET),封装为 SOT-23,面向低压高侧开关与便携设备的功率控制场景。器件额定漏源电压 Vdss 为 20V,连续漏极电流 Id 标称 2.3A,适合在 20V 及以下系统中替代小功率开关元件。

二、主要电气参数

  • 类型:P 沟道 MOSFET(P-channel)
  • Vdss(漏源电压):20 V
  • Id(连续漏极电流):2.3 A
  • RDS(on)(导通电阻):约 90 mΩ(VGS = 4.5 V 条件下)
  • Pd(耗散功率):1.4 W(SOT-23,实际热性能依 PCB 散热而定)
  • Vgs(th)(栅极阈值):0.7 V(在 IG = 250 μA 测试条件)
  • Qg(总栅极电荷):约 3.3 nC(在 VGS = 2.5 V 条件下)
  • Ciss / Coss / Crss:405 pF / 75 pF / 55 pF
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 封装:SOT-23

三、电气与热性能要点

  • 导通电阻 90 mΩ 是在 VGS = 4.5 V 条件下测得;在较低栅压(如 2.5V 或 3.3V)驱动时,RDS(on) 会显著增大,需在选型时评估导通损耗。
  • 栅极电荷量较小(3.3 nC @2.5V)且 Ciss 约 405 pF,便于 MCU 或小功率驱动器直接驱动,开关损耗和驱动功耗较低。
  • 封装耗散功率为 1.4 W,但实际允许电流受 PCB 铜箔面积与环境温度影响较大,建议做热仿真或按经验增加散热铜箔以保证可靠工作。

四、典型应用场景

  • 低压系统的高侧开关(电源选择、负载开关)
  • 电池供电设备的电流切换与反向保护
  • 便携式与消费电子中小功率开关与路由
  • 需要小体积封装(SOT-23)的功率控制电路

五、设计与使用建议

  • 使用前确认目标电路中 VGS 的最大幅值(确保不超过器件额定值);在高侧开关应用中,注意源极电位变化对 VGS 的影响。
  • 若在 3.3V 或 2.5V 驱动条件下使用,应验证实际 RDS(on) 和结温升,以避免过热;若需要更低导通阻抗,考虑提升栅极驱动电压或采用并联器件(需评估共享电流能力)。
  • 驱动感性负载时,应配置合适的续流或吸收回路,避免器件承受过大的反向恢复应力。
  • PCB 设计时在器件下方和铜箔上安排合理散热区,必要时增加过孔与底层散热层。

六、封装与可靠性

SOT-23 小尺寸封装适合空间受限的设计,工作温度覆盖 -55 ℃ 到 +150 ℃,适应较宽的工业与消费类环境。常规布局与焊接工艺即可满足大多数应用,但对于连续大电流场合应重点考虑热管理与长时间可靠性测试。

总结:SI2301DS-ES 以其低栅极电荷、适中的导通阻抗与小体积封装,适用于 20V 以下系统的高侧开关和电源管理场景。设计时需关注栅极驱动电压与热耗散,以发挥其最佳性能。

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
