SMBJ16CA 产品概述
一、产品简介
SMBJ16CA 是江苏长电/长晶（CJ）提供的一款双向瞬态电压抑制二极管（TVS），封装为 SMBG（SMBJ 型封装）。器件设计用于在瞬态过电压事件（如雷击浪涌、开关瞬变、电磁干扰）发生时快速夹断并吸收能量，保护下游电路元件。其稳态工作反向截止电压（Vrwm）为 16V，典型击穿电压约 19.7V，钳位电压约 26V（在 10/1000µs 波形测试下），非常适合中低压电源和信号线的浪涌保护。
二、主要性能参数
- 极性：双向（Bidirectional），适用于极性可变或交流线路的保护
- 反向截止电压 Vrwm：16 V
- 击穿电压 Vbr（典型）：19.7 V
- 钳位电压 Vc（10/1000µs）：约 26 V
- 峰值脉冲电流 Ipp（10/1000µs）：23.1 A
- 峰值脉冲功率 Ppp（10/1000µs）：600 W
- 反向漏电流 Ir：≤ 5 µA（在 Vrwm 下）
- 类型：瞬态抑制二极管（TVS）
- 品牌/产地：CJ（江苏长电 / 长晶）
- 封装：SMBG（SMBJ）
三、典型应用场景
- 工业电源总线、直流供电系统的浪涌保护
- 交流或双向信号线、接口保护（例如通讯端口、控制线）
- 电源模块输入端、DC-DC 转换器防护
- 交通、仪表、楼宇自动化等需要抗浪涌能力的场合
四、使用与可靠性要点
- 选型时注意 Vrwm 应高于电路正常工作电压并留有余量，避免常态触发。
- 峰值脉冲参数基于 10/1000µs 波形，实际应用中需评估浪涌能量与器件吸收能力的匹配。
- 反向漏电流低（≈5µA），适合对泄漏敏感的电源/信号线路，但长期高温下漏电可能上升，应考虑温度影响。
- 封装为 SMBG，具有良好散热及可焊性；安装时应保证良好散热路径并遵循焊接温度曲线以避免热损伤。
- 推荐在电路板布局时将 TVS 靠近被保护端口放置，缩短导线长度以提高有效保护性能。
五、封装与标识
SMBJ16CA 采用 SMBG/SMBJ 体积尺寸，便于手工或回流焊装配，封装上通常印有型号或批次代码。常见封装优势包括较高的功率吸收能力和较好的机械强度。
SMBJ16CA 以其 16V 工作电压、26V 钳位和 600W 峰值功率的组合，适合需要稳定钳位并能承受短时高能浪涌的中低压保护场合。在实际设计中，应综合考虑线路额定电压、浪涌类型与频率、环境温度及散热条件，确保器件长期可靠工作。

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.
