SMBJ16CA (SMB) TVS 二极管 产品概述
一、主要特性
SMBJ16CA 是晶导微电子出品的双向瞬态电压抑制器（TVS），采用SMB封装，适用于对电源及信号线进行浪涌和浪涌尖峰保护。主要参数包括：钳位电压（Vc）26V、反向工作电压（Vrwm）16V、击穿电压（Vbr）19.7V、峰值脉冲功率Ppp 600W（10/1000μs），对应峰值脉冲电流Ipp 23.1A；结电容Cj≈390pF，反向漏电流Ir≈1μA；工作温度范围-65℃～+150℃。
二、典型电气说明
- Vrwm=16V 表示器件在正常反向工作时的耐受电压上限，适配常见12V/15V系统的稳态条件。
- Vbr=19.7V 为击穿起始电压，超过此值进入导通，随电流上升至钳位电压26V以限制过压。
- Ppp=600W（10/1000μs）为脉冲能量能力，26V×23.1A≈600W，表明器件能吸收一次高能浪涌脉冲（非连续功率）。
- Cj=390pF 较大，适合电源线或低频信号保护，但对高速差分/高频接口可能产生显著影响。
三、典型应用场景
- 汽车电源系统（12V/24V 降压/保护，需注意浪涌等级与车规环境匹配）
- 工业控制、逆变器及电源模块的输入端浪涌吸收
- 电源线、交流/直流接口的双向过压保护
（不推荐用于对传输速率和低电容要求严格的高速数据线）
四、封装与热管理
SMB 封装便于表面贴装与散热。推荐布板要点：器件靠近需保护的输入端，走线尽量短且宽以降低寄生电感和热阻；必要时在器件附近增加散热铜箔或过孔。注意脉冲能量不可长期承受，连续稳态功耗需严格按规格控制。
五、使用建议与注意事项
- 对高能雷击或反复浪涌场合，应配合保险丝、限流电阻或多级保护方案，避免单器件超载。
- 结电容较大，不适合高速信号通道；对接口敏感的应用考虑低Cj型号。
- 存储与回流焊遵循封装温度规范，避免超温和机械应力。
- 设计时留意工作环境温度范围及泄漏电流对电路待机功耗的影响。

Send RFQ
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.
