SMBJ36CA 产品概述
一、主要参数与特性
SMBJ36CA 是 DOWO（东沃）出品的双向瞬态电压抑制（TVS）二极管，采用玻璃钝化芯片工艺，封装为 SMB（DO-214AA）。主要电气参数如下：
- 极性：双向
- 反向截止电压 Vrwm：36 V
- 击穿电压 VBR：40 V
- 钳位电压（典型）：58.1 V
- 峰值脉冲电流 Ipp：10.33 A
- 峰值脉冲功率 Ppp：600 W（波形 10/1000 μs，重复率 0.01%）
- 反向漏电流 Ir：1 μA
- 工作温度范围：-55 ℃ ～ +150 ℃
此外具备低泄漏、极快响应和优秀钳位能力，符合 RoHS 要求。
二、性能详解
SMBJ36CA 在遭受瞬态冲击（如雷击诱导浪涌或开关瞬变）时，能迅速进入导通状态，将过高电压限制在约 58.1 V 的钳位电压，从而保护下游电路。600 W（10/1000 μs）的大能量承受能力，适合较长持续时间的浪涌情形；10.33 A 的峰值脉冲电流指标表示单次冲击下的瞬时抗冲击能力。低至微安级的反向漏电保证在正常工况下对电路影响最小。
三、封装与机械特性
SMB（DO-214AA）封装具备良好的散热与焊接兼容性，适合波峰或回流焊工艺。玻璃钝化芯片提高了 PN 芯片表面的稳定性和可靠性，在高温与高湿环境中表现更佳。适用于密度中等、需要一定能量吸收能力的电路板布局。
四、典型应用场景
- 工业控制与电源系统的输入端浪涌保护
- 通信设备、基站和路由器的端口防护
- 汽车电子对车载浪涌与静电放电的抑制（需满足汽车级要求时另行确认）
- 电力监控、安防和照明驱动的浪涌抑制
五、选型建议
选择 SMBJ36CA 时，应注意：
- 工作电压裕量：Vrwm 36 V 适用于直流或双向交流系统的额定站立电压接近该值的场合，应留足安全余量。
- 双向与单向：本型号为双向，适合交流或正负反转可能的环境；若仅需单向保护可考虑单向型号。
- 能量需求：若可能遇到更高能量或更频繁冲击，应选用更大功率或并联/级联方案。
- 环境与寿命：高温工作场合需关注封装散热与额定结温。
六、安装与使用注意事项
- 遵循标准焊接曲线，避免过热导致封装或内部焊点损伤。
- PCB 布局上尽量将 TVS 靠近被保护端口，减小引线电感以提高响应效果。
- 对地/对称回路应保证良好接地，以便把能量及时泄放。
- 储存时避免潮湿、高温环境，开封后按常规元件防潮处理。
七、可靠性与合规
玻璃钝化工艺和 SMB 封装带来较好的长期稳定性与机械强度。产品通过 RoHS 要求，适用于广泛的商业与工业级应用。针对特殊行业（如汽车、医疗），请参考厂商完整可靠性测试报告与资格认证。
总结：SMBJ36CA 提供高能量吸收、快速响应与低泄漏特性，适合多种需要中高能量浪涌保护的场景。选择时结合系统电压、冲击能量与安装条件，可发挥其最佳保护效果。

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.
