P4SMA13CA 产品概述
一、产品简介
P4SMA13CA 为 Littelfuse（美国力特）出品的双向瞬态电压抑制二极管（TVS），采用 SMA（DO-214AC）封装，2 引脚设计，适用于对称正反向的瞬态浪涌抑制。器件标称反向截止电压（Vrwm）11.1V，钳位电压（Vc）18.2V，能够在工业、通信和汽车电子等领域为敏感器件提供高效的瞬态保护。
二、主要性能参数
- 极性：双向（Bi-Dir）
- 反向截止电压 Vrwm：11.1 V
- 击穿电压（典型）：13.7 V
- 钳位电压 Vc（脉冲条件）：18.2 V
- 峰值脉冲电流 Ipp：22.5 A（10/1000 μs 波形）
- 峰值脉冲功率 Ppp：400 W（10/1000 μs）
- 反向漏电流 Ir：≤1 μA（常温）
- 工作温度范围：-65 ℃ 至 +150 ℃
- 防护等级：满足 IEC 61000-4-4（纹波/快速瞬变）与 IEC 61000-4-2（静电放电）测试标准
三、特点与优势
- 高能量吸收能力：400 W（10/1000 μs）允许器件吸收短时大能量冲击，适合配合线路级、防雷和电源浪涌保护。
- 双向保护：对正负极性瞬态均可有效钳位，适用于交流或双向传输线。
- 低漏电流：Ir ≤1 μA，保证对待保护电路的微弱信号影响极小。
- 宽工作温度：-65 ℃ 至 +150 ℃，适应严苛环境与高温应用场景。
- 标准封装：SMA 封装便于自动化贴装和替换，兼顾散热与耐冲击能力。
四、典型应用场景
- 汽车 12V/24V 电源系统及车载电子模块的瞬态抑制
- 工业控制设备、PLC 接口、继电器驱动线路的浪涌保护
- 通信设备、交换机、电源模块的端口防护（符合 IEC 静电与快速瞬变等级）
- 电池管理、逆变器输入/输出端的过压吸收
五、布板与散热建议
- 贴近受保护引脚或接口布置，缩短导线与走线长度以降低串联电感与回路阻抗。
- 对高能量冲击线路，可配合熔断器、限流电阻或电感使用，分担能量并避免过热。
- 保持良好铜箔散热、必要时在焊盘下方或旁侧增加散热铺铜，确保在重复冲击工况下温升可控。
- 设计时考虑钳位电压与被保护器件耐压裕量，确保在最大脉冲条件下不超过下游器件极限。
六、封装与可靠性
P4SMA13CA 使用 DO-214AC（SMA）封装，适配标准 SMT 工艺与回流焊流程。产品通过相关工业标准测试，满足 IEC 61000-4-2 与 IEC 61000-4-4 的抗扰度要求，具备良好的长期可靠性和环境适应能力。包装形式通常为带卷（T/R），便于批量生产使用。
如需在特定应用中验证钳位效果或进行热仿真，建议结合实际电路工况（线长、寄生电感、重复脉冲频率）进行样机测试，以确定最佳保护方案。

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.
