SMF24CA(CBZ)SOD-123FL — 产品概述

一、产品简介

SMF24CA(CBZ)为晶导微电子推出的一款高能瞬态抑制二极管(TVS),封装为SOD-123FL。其反向截止电压Vrwm为24V,击穿电压约29.5V,钳位电压为38.9V,能在10/1000μs波形下承受200W峰值脉冲功率,峰值脉冲电流Ipp为5.1A,静态反向漏电流仅1μA。工作温度范围宽:-55℃至+150℃,适合苛刻环境下长期可靠工作。

二、主要性能特点

  • 高能量吸收能力:10/1000μs下Ppp=200W,适合线路级浪涌保护。
  • 有效钳位:Vc=38.9V,可把高幅度脉冲限制在安全电压范围。
  • 低漏电流:Ir≈1μA,适用于对静态功耗敏感的系统。
  • 宽温区:-55℃~+150℃,满足工业及部分汽车等级温度要求。
  • 紧凑封装:SOD-123FL,利于密集PCB布局与自动贴装。

三、典型电气参数说明

  • 反向截止电压(Vrwm):24V,推荐用于24V系统的稳态保护。
  • 击穿电压(Vbr):29.5V,表征进入击穿导通区的起始电压。
  • 钳位电压(Vc):38.9V,在指定脉冲条件下的稳态最大电压。
  • 峰值脉冲功率/电流:200W / 5.1A(10/1000μs),适合雷击或开关瞬态能量吸收。

四、应用场景

  • 24V供电总线及工业控制设备保护;
  • 通信接口、电源端子防雷浪涌与开关冲击抑制;
  • 汽车电子(非关键安全回路)、车载辅助电源保护;
  • 工业传感器、变送器及I/O端口瞬态保护。

五、封装与布局建议

SOD-123FL体积小、焊接方便。建议将器件尽量靠近被保护端口或连接器放置,缩短走线;在焊盘周围留足铜箔以增强散热;必要时在器件地端加宽地铜或采用热沉垫,提高脉冲能量下的散热能力;若系统有更高能量需求,可并联或选用更大封装器件。

六、选型注意事项

选择时应以系统稳态电压匹配Vrwm为先,确认钳位电压是否对下游器件安全;评估脉冲能量谱与10/1000μs规格的适配性;关注封装对PCB空间与散热的影响。如需双向保护或更高功率等级,可考虑系列其他型号或更大封装替代。

总结:SMF24CA(CBZ)以其24V级的稳态匹配、200W脉冲吸收能力、低漏电与宽温区特性,是工业与通信类24V线路瞬态抑制的实用选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
