SMAJ36A 产品概述
SMAJ36A 是 CJ（江苏长电/长晶）出品的一款单向 TVS 晶体管，专为抑制瞬态过压（雷击、浪涌、静电放电等）设计。器件具有高能量吸收能力和宽工作温度范围，适用于电源线与信号线的浪涌保护。
一、主要特性
- 极性：单向（单向导通，反向截止）
- 类型：瞬态电压抑制二极管（TVS）
- 高峰值脉冲吸收能力：Ppp = 400 W（10/1000 µs）
- 峰值脉冲电流：Ipp = 6.9 A（10/1000 µs）
- 工作温度范围：-55 ℃ ～ +150 ℃
- 封装：SMAG（SMA 封装型）
二、电气参数（典型/标称）
- 反向截止电压 Vrwm：36 V
- 击穿电压 Vbr：44.2 V
- 钳位电压 Vcl：58.1 V（在规定脉冲条件下）
- 反向泄漏电流 Ir：5 µA（在 Vrwm 条件下或典型测试电压） 说明：以上数值为典型/标称值，具体设计时请参考厂方完整 datasheet 及测试条件。
三、典型应用
- 36 V 级电源线上对浪涌保护（如汽车电子、工业电源）
- 通信设备、逆变器、充电桩的供电/控制回路保护
- 工业控制、测量仪表与嵌入式系统的输入/输出防护
四、封装与安装建议
- SMAG（SMA）封装便于自动贴装与回流焊工艺；建议遵循 PCB 布局的接地环和低阻抗接地回路，以提升泄放能量能力和抑制共模噪声。
- TVS 近源放置效果最佳：靠近被保护端口与接地侧放置，焊盘和走线尽量短、粗。
五、选型与可靠性建议
- 当系统最大可能冲击电流接近或超过 Ipp 时，应选用更高能量等级的 TVS 或并联使用并经热、冲击试验验证。
- 钳位电压需小于被保护器件允许的最大耐压；SMAJ36A 的钳位约 58.1 V，适用于需限制在此电平的场合。
- 注意器件在高温下的功耗与热阻，长期吸能会降低寿命。
六、注意事项
- 采购时确认 CJ 厂家/代理商与完整型号（SMAJ36A）及批次，避免规格差异。
- 焊接建议按厂方回流曲线，避免超时高温导致性能退化。
- 设计中保留适当的安全裕度并进行实际浪涌试验以验证整机保护效果。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
