PSD12C-LF-T7 是友台半导体(UMW)推出的一款双向瞬态电压抑制二极管(TVS),专为瞬态过压、静电放电(ESD)以及雷击/浪涌事件的快速钳位保护而设计。器件工作电压为12V(反向工作电压 Vrwm),在面对脉冲冲击时能将电压有效钳位至典型 19V 左右,峰值脉冲功率能力高达 400W(8/20µs 波形),同时保持极低的反向漏电流(Ir ≤ 1µA)和适中的结电容(Cj ≈ 50pF),适用于多种工业、通信与消费电子的输入保护场合。
(注:以上为典型/标称值,应以完整器件数据手册中的条件与曲线为准。)
PSD12C-LF-T7 采用 SOD-323 小型表面贴装封装,适合自动化贴装流程与高密度 PCB 设计。SOD-323 结构薄且焊接面积有限,焊接过程需关注回流曲线以确保焊点可靠性。器件已通过 IEC 61000 系列的 ESD、EFT 与浪涌防护标准验证,能满足多数工业与民用场景的兼容性要求。
PSD12C-LF-T7 是一款针对 12V 级别系统设计的双向 TVS 器件,具备 400W 峰值脉冲能量吸收能力、19V 钳位电压(典型)及符合 IEC 61000-4-2/4-4/4-5 的防护等级。其小尺寸 SOD-323 封装与低漏电流特性,使其在工业接口、电源输入与一般通信端口的瞬态保护中具有较高的实用性。选型时应综合考虑系统电压、重复冲击能量和信号带宽对结电容的敏感度,按厂商数据手册的试验条件进行验证与热管理设计。若需进一步的电气曲线、脉冲耐受循环或焊接推荐,请参阅友台半导体的完整 PSD12C-LF-T7 数据手册。

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.
