P3500SC 是 TECH PUBLIC(台舟电子)推出的一款功率晶闸管(可控硅),采用 SMB(DO-214AA)表面贴装封装。该器件针对中小功率交流与脉冲开关应用设计,具有较低的断态电容、较小的漏电流和较高的脉冲承受能力,适合用于交流控制、电源保护和固态继电器等场景。
注:上述参数基于提供的数据列出。具体测试条件(如电流、温度、波形)会影响典型值与极限值,请以正式规格书为准进行最终设计。
特别提示:断态峰值电压 Vdrm = 320 V,在直接用于 230 VAC(峰值约 325 V)系统时,裕量有限,应慎重选择或采用额外保护电路(如 RC 吸收、浪涌抑制器)以提高可靠性;若系统存在较大浪涌或长期过压风险,建议选用额定电压更高的器件或采取电压分担措施。
SMB(DO-214AA)为常见的 SMD 功率封装,便于自动贴装与回流焊接。由于器件在导通时可能产生较大的功耗(若 Vt 表示导通压降,P ≈ Vt × It),例如在 2.2 A 连续导通且导通压降为数伏时,器件热耗不可忽视。设计时应注意:
如果需要,我可以根据您具体的应用电压等级、负载类型和驱动条件,给出更详细的热设计建议、驱动电路原理图与 PCB 布局要点。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
