PESD12VS1UB-N 是伯恩半导体(BORN)推出的一款单向静电放电保护器件,采用 SOD-523 小体积封装。器件针对高能脉冲与静电放电事件提供可靠钳位与承受能力,可用于敏感信号线与接口的过压保护。
符合并适用 IEC 61000-4-2(静电放电)、IEC 61000-4-4(快速瞬变/脉冲群)与 IEC 61000-4-5(雷击冲击)相关防护等级要求,能有效应对工业与消费类环境下常见的电磁脉冲与静电事件。
采用 SOD-523 超小型封装,便于在空间受限的移动设备与高密度 PCB 上布局。小封装带来更小的寄生电感,但需注意焊接工艺以保证可靠性。
若目标线路电压 ≤12V 且需单向保护,PESD12VS1UB-N 提供低漏电、快速响应与高能量吸收能力;对极低电容要求的高速差分信号,应评估 55pF 对信号带宽的影响,必要时考虑更低 Cj 的器件。对于更高的连续脉冲能量或更低钳位需求,可与系统级浪涌保护器配合使用。
PESD12VS1UB-N 在体积、响应速度与脉冲承受能力之间取得平衡,适合需要可靠瞬态抑制且 PCB 空间受限的场景。

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.
