SMCJ30A TVS 瞬态电压抑制二极管（单向）产品概述
一、产品简介
SMCJ30A 为 GOODWORK（固得沃克）出品的单向 TVS 二极管，基于 GPP 工艺芯片制造，专为抑制线路瞬态过电压设计。器件在高温和恶劣环境下表现稳定，适合对抗雷击、开关瞬变及静电放电等冲击事件，保护下游敏感器件和电源模块。
二、主要性能参数
- 极性：单向
- 反向截止电压 Vrwm：30 V
- 击穿电压 VBR（测试条件）：33.3 V（典型）
- 钳位电压 Vc：48.4 V（于峰值脉冲条件下）
- 峰值脉冲电流 Ipp：31 A
- 峰值脉冲功率 Ppp：1500 W（10/1000 μs 或厂方指定波形）
- 反向电流 Ir：5 μA（常温）
- 通道数：单路
- 工作温度：-55 ℃ ~ +150 ℃
- 封装：SMC (DO-214AB)
三、结构与封装
SMC (DO-214AB) 为中等功率封装，具有良好的热散能力和焊接可靠性，适合波峰或回流焊工艺。封装尺寸适配标准 PCB 布局，便于与熔断器、滤波元件和接地结构结合实现整板防护。
四、主要特性与优势
- 采用 GPP 工艺芯片，具备低漏电、高对档率及优良的高温稳定性；
- 低反向电流（5 μA），降低静态能耗；
- 高峰值功率承受能力（1.5 kW）和较大瞬态电流（31 A），能有效吸收工业级冲击脉冲；
- 单向设计适用于直流供电系统，钳位电压明确，有利于保护电源与半导体器件。
五、典型应用
- 24 V 工业与汽车电源防护；
- 开关电源（SMPS）输入端浪涌抑制；
- 通信设备、电信接口与基站防雷；
- 工业控制设备、仪器仪表及电源模块的浪涌保护。
六、选型与使用建议
- 确认系统工作电压不超过 Vrwm（30 V），并在可能的浪涌工况下钳位电压对被保护元件可接受；
- 留出充分的接地回流路径和散热区域，避免热集中；
- 对于重复或大能量冲击场合，考虑并联合适的限流元件或提升器件功率余量；
- 焊接与存储遵循厂家温度曲线与抗湿防护要求，装配时注意极性标识，避免反向误装。
SMCJ30A 适用于要求中高能量吸收能力与高温稳定性的工业级防护场景，是对 24~30 V 直流系统进行瞬态过压保护的可靠选择。若需详细电气特性曲线与测试波形，请参考 GOODWORK 正式 Datasheet。

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.
