SVF3878PN 是士兰微(SILAN)出品的一款高压 N 沟增强型场效应管,适用于高压开关场合。器件额定漏源电压 Vdss = 900V,连续漏极电流 Id = 9A,耗散功率 Pd = 150W(注意受散热条件限制),在 Vgs = 10V 时 RDS(on) ≈ 1Ω。器件工作温度范围为 -55℃ 到 +150℃,封装为 TO-3P-3,适合需要良好散热的功率应用。
TO-3P-3 封装利于与散热片直接安装与良好导热,适合大功率应用。建议在 PCB 侧增加散热铜箔并使用热过孔连通多层铜层,以降低结壳热阻;安装时注意机械与热界面处理以保证长期可靠性。
SVF3878PN 以 900V 耐压与 9A 连续电流能力,结合 TO-3P-3 的散热特性,适合高压开关电源与 PFC 等场合。设计时需特别注意较大的栅极电荷与开关损耗、合理的栅极驱动和完善的热与过压保护,参考厂方完整数据手册并据此做电路与散热设计可获得可靠的长期运行表现。

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.
