IRFR48ZTRPBF 是一款高性能 N 沟道功率 MOSFET,面向中高电流开关应用。核心参数如下:
该器件在 VGS=10 V 时 RDS(on) 极低,适用于需要低导通损耗的开关或降压转换器。VGS(th) 约 4 V,说明在较低栅压下导通并不充分,建议采用 10 V 门极驱动以获得标称 RDS(on)。
总栅极电荷 Qg=60 nC 属于中等水平,驱动器需具备较好的瞬态电流能力以实现快切换,避免因缓慢上升/下降引起的开关损耗与过热。反向传输电容 Crss=160 pF 会产生米勒效应,在电压翻转时需注意栅极回路与驱动回路的布线以减少寄生电感与振铃。
DPAK (TO-252AA) 为常用表面贴装封装,散热主要通过焊盘与底部铜箔向 PCB 传导。器件标称热耗散能力需参考实际 PCB 铜量与环境对流条件,建议在高功率应用中:
器件耐高温范围宽(-55 ℃ ~ +175 ℃),适合苛刻环境应用。但在选型时应注意:
总结:IRFR48ZTRPBF 在 55 V/42 A 级别应用中提供低 RDS(on) 的优良导通性能,配合恰当的驱动与散热设计,可在开关电源、驱动与负载开关场景中实现高效可靠的电源管理。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
