XP202A0003PR-G 产品概述

XP202A0003PR-G 为 TOREX(特瑞仕) 推出的 P 沟道功率 MOSFET,适用于中低压、高效率的高侧开关与保护电路。器件采用 SOT-89 封装、具有较低导通电阻与适度开关特性,适配便携式与工业控制等对体积和成本敏感的场景。

一、主要参数

  • 类型:P 沟道 MOSFET
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:5 A
  • 导通电阻 RDS(on):59 mΩ @ Vgs = 10 V
  • 功耗 Pd:1.5 W
  • 阈值电压 Vgs(th):1.2 V
  • 总栅极电荷 Qg:10 nC @ Vgs = 10 V
  • 输入电容 Ciss:450 pF;反向传输电容 Crss:80 pF;输出电容 Coss:110 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-89

二、核心特性说明

  • 低 RDS(on):59 mΩ 在 Vgs=10V 条件下保证较低导通损耗,适合要求较低导通压降的高侧开关应用。
  • 适度驱动能耗:总体栅极电荷 10 nC 与 Ciss/Crss 指标,使得在中低频率开关时驱动损耗可控。
  • 高温适应性:宽工作温度范围满足工业与车载类环境要求(但需考虑封装散热限制)。
  • P 沟道优势:便于作为正电源(高侧)直接开关,省去升压栅极驱动电路,简化设计。

三、封装与热管理

SOT-89 在体积上优于 TO-252 等大封装,但热阻相对较高。器件额定耗散功率为 1.5 W(一般在良好散热条件下),实际应用中应:

  • 在 PCB 上使用大面积铜箔散热(下方与周边敷铜)以降低结到环境热阻;
  • 在连续大电流场景下按温升曲线对电流进行降额;
  • 考虑使用热过载保护与温度监测以保证可靠性。

四、典型应用场景

  • 电池供电设备的高侧开关与负载断开;
  • 电源管理与反向保护电路;
  • 低压直流电机驱动中的方向/保护电路(需注意功耗与散热);
  • 信号电源隔离与多路电源切换。

五、使用建议

  • 驱动逻辑:P 沟道 MOSFET 在导通时 Vgs 需为负值(例如源电压为 +12V,要使其充分导通,门极需拉至约 +2V 左右以产生约 -10V 的 Vgs)。关断时将栅极拉到与源同电位。
  • 开关速度控制:为避免振铃与降低 EMI,建议在栅极串联小电阻(10–100 Ω),并根据 Crss 采用合适的缓冲或斜率控制。
  • 热降额:当环境温度升高或散热受限时,应按 Pd 与热阻进行电流或占空比降额。
  • 保护措施:并联整流二极管、RC 缓冲或 TVS,可抑制开关瞬态与防止瞬态过压。

六、注意事项与可靠性

  • 虽然 Id 标称 5A,但 SOT-89 封装的持续大电流受限于 PCB 散热设计,应避免长时间满载运行;
  • Vgs 最大允许值与绝对极限请参照器件手册,避免超越以免击穿栅氧;
  • 在高 dV/dt 场合,Crss(Miller 电容)会影响栅极电压,可能引起意外开/关,需通过门极电阻或阻尼网络处理。

总结:XP202A0003PR-G 在小体积封装下提供可靠的 30V、5A 级 P 沟道开关能力,适合用于空间受限且需高侧开关的电源管理场合。合理的驱动与散热设计是发挥其性能与保证长期可靠性的关键。

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
