PTVSHC1TF24VBH 产品概述
一、概述
PTVSHC1TF24VBH 是 Prisemi（芯导）推出的一款表面贴装型瞬态电压抑制器（TVS），用于对抗静电放电（ESD）和瞬态浪涌（Surge）侵扰。器件设计用于在电路遭受高能脉冲时迅速箝位电压，保护后端敏感元件正常工作，广泛适用于通讯接口、接口板、末端设备与工业控制场合的浪涌与静电防护。
二、主要参数
- 钳位电压（Vc）：38 V
- 击穿电压（Vbr）：30 V
- 反向截止电压（Vrwm）：24 V
- 峰值脉冲功率（Ppp）：6.5 kW @ 8/20 μs
- 峰值脉冲电流（Ipp）：185 A @ 8/20 μs
- 结电容（Cj）：315 pF
- 反向漏电流（Ir）：1 μA
- 防护等级：符合 IEC 61000-4-4（快速瞬变）与 IEC 61000-4-2（静电放电）
- 封装：SOD-123FL（低剖面表面贴装）
三、产品特性
- 强劲的瞬态承受能力：在标准 8/20 μs 波形下能吸收高达 6.5 kW 的脉冲能量，适用于中大能量浪涌场景。
- 有效箝位：38 V 钳位电压在保护器件与被保护电路之间提供可靠电压压制。
- 低漏电和可控结电容：1 μA 低反向电流利于降低静态功耗，但 315 pF 的结电容对极高速或高频信号链路需评估影响。
- 紧凑封装：SOD-123FL 适合表面贴装工艺，占板面积小，便于自动化生产。
四、典型应用场景
- 串行接口与数据线保护（UART、CAN、RS‑485 等需评估结电容影响）
- 电源输入端浪涌抑制与端口保护
- 工业控制设备、楼宇自控与安防设备的输入输出保护
- 消费电子与通信终端的静电防护
五、封装与布局建议
- 将 TVS 尽量靠近被保护端口或接口焊盘放置，缩短导线与走线长度以降低感抗。
- 接地端采用宽铜箔或大面积接地平面以利热量扩散与脉冲回流路径，焊盘与走线应短而粗。
- 对于高频或高速数据信号，需评估 315 pF 结电容对信号完整性的影响，必要时考虑在保护前使用串联电阻或采用低电容型 TVS。
六、选型与使用注意事项
- 确认工作电压：Vrwm 为 24 V，应高于电路正常工作电压并留有裕量。
- 根据最大冲击能量和系统可能遭受的浪涌等级选择适当 Ppp 能力；本器件适合中高能量脉冲防护。
- 结电容对高速接口影响不可忽视，若用于 GHz 级或差分高速信号应进行信号完整性验证。
- 封装热性能有限，若频繁遭受大能量脉冲，应评估 PCB 散热和并联多只器件的策略。
Prisemi（芯导）PTVSHC1TF24VBH 提供了兼顾抽屉式浪涌防护能力与 SMT 制程便利性的解决方案，适合需要中高能量脉冲耐受且对封装尺寸有要求的保护场合。如需样片、详细封装图或典型电路建议，可联系供应商获取完整资料与应用参考。

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.
