5.0SMDJ22CA 瞬态抑制二极管 产品概述
一、产品简介
5.0SMDJ22CA 是东沃（DOWO）推出的一款双向 TVS 瞬态抑制二极管，封装为 SMC（DO‑214AB）。器件专为抗雷击、浪涌和开关瞬变设计，用于在脉冲能量注入时迅速钳位电压，保护后端电路免受损坏。
二、主要电气参数
- 类型：双向 TVS
- 反向截止电压 Vrwm：22 V（反向工作电压）
- 击穿电压（Vbr）：24.4 V
- 钳位电压（Vclamp）：35.5 V
- 峰值脉冲功率 Ppp：5 kW（按 10/1000 µs 波形）
- 峰值脉冲电流 Ipp：140.8 A
- 反向泄漏电流 Ir：≤ 5 µA
- 封装：SMC (DO‑214AB)
- 品牌：DOWO（东沃）
三、关键特性与优势
- 高能量吸收：5 kW（10/1000µs）能量处理能力，适合直流和低频电力线路的雷击/浪涌防护。
- 低钳位电压：35.5 V 钳位可在越过 Vrwm 时迅速限制电压峰值，保护后续器件。
- 双向设计：对称钳位，适用于正负极性瞬变（如双向电源与交流耦合电路）。
- 低漏电：工作状态下漏电低（≤5 µA），不影响正常电路工作。
四、典型应用场景
- 24 V 工业电源与控制系统浪涌保护
- 通信与基站电源防护
- 电机驱动及工业现场总线接口
- 需要双向防护的交流耦合或可逆电路
五、使用与布板建议
- 靠近被保护端（输入或接口）放置，最短走线连接至地/回流端，以保证钳位回路低阻抗。
- 对于重复冲击或长时间运行场景，应配合熔断器或限流元件进行保护与能量分流。
- 在高浪涌环境，按规范考虑器件热耗散与间歇时间，避免超频繁冲击引起失效。
六、封装与可靠性注意事项
- SMC（DO‑214AB）封装支持常规回流焊工艺，但请参考厂商的回流曲线与防潮等级（MSL）要求进行贴装与回流。
- 器件额定能量为单次或短时冲击能力，重复能量需按应用环境做热与电气裕量评估。
- 推荐在器件选择和系统设计时，结合实际浪涌特性（波形、次数）进行仿真与验证，以确保长期可靠性。

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.
