PSOT12C 产品概述 — TVS/ESD 静电与浪涌保护（二极管）
一、产品简介
PSOT12C（品牌：TECH PUBLIC / 台舟电子）为面向12V工作电压系统的瞬态抑制二极管（TVS/ESD），采用SOT-23小封装。器件专为抑制静电放电（ESD）、电快速瞬变（EFT）及雷击/浪涌瞬态而设计，在工业、通讯、汽车电子及消费类设备中提供可靠的线对地/线对线过压保护。
二、主要参数
- 反向截止电压 Vrwm：12 V
- 击穿电压 Vbr：15 V（典型）
- 钳位电压 Vc：30 V（在 Ipp 条件下）
- 峰值脉冲电流 Ipp：15 A（8/20 µs）
- 峰值脉冲功率 Ppp：450 W（8/20 µs）
- 反向电流 Ir：≤100 nA（常温）
- 工作温度：-55 ℃ ~ +125 ℃
- 结电容（Cj）：提供约 100 pF 与 40 pF 两种版本，适配不同速率信号
- 防护等级：符合 IEC 61000-4-2（ESD）、IEC 61000-4-4（EFT）、IEC 61000-4-5（浪涌）
三、产品特性与优势
- 小体积 SOT-23 封装，便于空间受限的 PCB 布局与自动贴装；
- 低漏电流（≤100 nA），适合对静态功耗敏感的系统；
- 高能量吸收能力（450 W@8/20µs），能有效钳位短时大幅度浪涌；
- 两档结电容选择：100 pF 适用于电源或低速信号保护；40 pF 则更适合高速数据线路，降低信号失真；
- 同时满足 ESD、EFT、浪涌三类工业级抗扰度标准，可靠性高。
四、典型应用场景
- 12V 电源输入与供电轨保护；
- 串行通讯接口保护（UART、CAN、LIN，选用低 Cj 型号更佳）；
- 工业控制器、PLC、传感器模块的接口防护；
- 消费电子与车载电子的局部浪涌与静电防护。
五、设计与使用建议
- 推荐将 TVS 器件尽可能靠近被保护器件或外部接口焊盘放置，走线最短、最粗；
- 对高速差分信号优先选用 40 pF 低电容版本以降低带宽影响；
- 对大电流浪涌或需要更高能量吸收时，可并联合适的气体放电管或串联限流（熔断器/电阻）共同保护；
- 注意焊盘与接地回路设计，确保有效将浪涌能量导入系统地。
六、封装与采购提示
- 封装：SOT-23，适配常用贴片工艺；
- 规格可选：根据应用选择 100 pF 或 40 pF 版本；
- 订购或样品需求建议注明：型号（PSOT12C）、结电容规格、数量及封装要求，以便快速匹配库存。
如需针对此器件的典型能量曲线、钳位特性曲线或 PCB 布局参考样例，可提供更详细的电气与布局资料以支持设计验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
