SMBJ30CA 产品概述
一、产品简介
SMBJ30CA 为 Leiditech（雷卯电子）出品的双向瞬态电压抑制二极管（TVS），用于抑制开关浪涌、雷击和电磁干扰引起的瞬态过压保护。该器件在典型工业与通信电源线上提供可靠的瞬态吸收能力，适配24V~30V等级电源系统。
二、主要参数
- 极性：双向（Bidirectional）
- 反向截止电压 Vrwm：30V（工作钳位/稳压点）
- 击穿电压 Vbrmin：33.3V
- 钳位电压 Vc：48.4V（通常在峰值脉冲电流下测得）
- 峰值脉冲电流 Ipp：12.4A（10/1000μs波形）
- 峰值脉冲功率 Ppp：600W（10/1000μs）
- 反向电流 Ir：≤1μA（Vrwm条件下）
- 封装：DO-214AA（SMB）
三、性能特点
- 高能量吸收：600W（10/1000μs）能量级别，可应对较强的瞬态浪涌。
- 低漏电流：在工作电压下漏电小于1μA，适合对静态功耗敏感的系统。
- 快速响应：TVS器件响应时间极短，能在瞬态初期迅速钳位，保护后级电路。
- 双向保护：适合交流或可正反向出现过压的线路，使用更灵活。
四、应用场景
- 24V/30V 工业控制电源、PLC接口保护；
- 通信设备电源和信号线防雷防浪涌；
- 控制模块、驱动电路、继电器接口、电源输入端的过压保护；
- 一般电子设备的瞬态抑制场合（非汽车AEC-Q认证专用场景需注意确认）。
五、封装与机械特性
封装为 DO-214AA（SMB），适合自动贴装与回流焊工艺。封装尺寸与业界通用 SMB 足以保证良好的散热与机械强度。推荐在PCB上靠近被保护器件或入线处布局，缩短引线和回路长度以降低寄生电感。
六、使用建议与注意事项
- 该器件为脉冲能量吸收元件，不能作为持续限压使用，长时间超额功率会导致损坏。
- 布局时保证接地面短而粗，以利热量和脉冲电流回流。
- 焊接遵循SMB封装常规回流温度曲线，避免超过封装允许的最高温度。
- 对于关键或高可靠性应用，建议做实际浪涌测试以确认系统裕量。
七、品牌与采购
产品型号：SMBJ30CA，品牌：Leiditech（雷卯电子），常见封装：SMB（DO-214AA）。采购时请确认参数一致性（尤其是钳位电压和脉冲功率条件），并索取器件数据手册与样品进行评估。

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.
