P4SMAJ15A_R1_00001 产品概述
一、产品简介
P4SMAJ15A_R1_00001 为 PANJIT（强茂）系列单向瞬态抑制二极管（TVS），封装为 SMA（DO-214AC）。器件针对脉冲浪涌和瞬态过压事件提供高能量吸收能力，额定脉冲功率可达 400W（10/1000µs），适用于对中短脉冲防护有较高要求的电路保护场景。
二、主要电气参数
- 极性：单向（适合对地单向保护电路）
- 反向截止电压 Vrwm：15V（建议工作电压接近但不超过此值）
- 击穿电压 Vbr：18.5V
- 钳位电压 Vcl：24.4V（在 Ipp=16.4A，10/1000µs 条件下）
- 峰值脉冲电流 Ipp：16.4A（10/1000µs）
- 峰值脉冲功率 Ppp：400W（10/1000µs）
- 反向电流 Ir：1µA（常温、额定电压下）
- 工作温度范围：-55℃ ~ +150℃
三、封装与热性能
SMA（DO-214AC）小型封装兼顾较好的热散能力与紧凑占板面积，适用于表面贴装工艺。器件在高温环境下仍能保持稳定的防护性能，但在长时高能量冲击下需要考虑 PCB 散热设计与热循环应力。
四、应用场景
- 12V/15V 电源系统的瞬态浪涌保护（例如汽车电子、车载子系统）
- 工业控制与电源接口输入保护
- 防止开关瞬变、浪涌及雷击耦合引起的过压伤害
- 通信接口、电源模块、充电设备等需要中等能量抑制的场合
五、设计与选型建议
- 将 TVS 尽量靠近被保护的引脚或连接点布置，缩短走线以降低感抗与延迟。
- 对于持续出现的大电流浪涌场合，应评估是否需要并联更高能量器件或增加熔断/限流元件。
- 选择 Vrwm 应不低于正常工作电压，但留有裕量；本器件 Vrwm=15V，适配 12V 类系统较为合适。
- 注意钳位电压在大电流时对下游器件的承受能力，必要时配合吸收型元件或滤波电路共同保护。
六、可靠性与包装
器件适配商业及工业等级温度范围，反向漏电小，长期稳定性好。PANJIT 提供卷带或盘装交付，便于 SMT 产线贴装与批量生产管理。
七、总结
P4SMAJ15A_R1_00001 以其 400W（10/1000µs）的高脉冲吸收能力、24.4V 的钳位性能及广泛的工作温度范围，适合用于 12V/15V 级别电源和信号线路的瞬态浪涌防护。针对具体应用建议结合实际工作电压、最大浪涌能量与 PCB 布局进行验证，以保证最佳保护效果与系统可靠性。若需更多详细规范参数或封装尺寸图，可参考 PANJIT 官方资料或联系供应商获取数据手册。

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.
