SA10CA/B 瞬态抑制二极管(TVS)产品概述

SA10CA/B是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),专为低电压电路的过压防护设计,具备宽温适应性、高脉冲耐受能力,广泛应用于工业控制、通信设备、汽车电子等领域。

一、产品核心定位

SA10CA/B属于双向TVS器件,核心作用是快速抑制电路中的瞬态浪涌电压,防止后级敏感元器件(如MCU、传感器、通信接口)因过压损坏。其针对10V左右工作电压的系统优化,平衡了防护性能与功耗控制,是低电压电路过压防护的高性价比选择。

二、关键电气性能参数详解

SA10CA/B的核心参数围绕“防护能力”与“正常工作兼容性”展开,具体如下:

  1. 反向截止电压(Vrwm):10V
    器件正常工作时(无浪涌),反向偏置下的最大允许电压,即被保护电路的工作电压需≤10V,确保器件不导通、不影响系统正常供电。
  2. 钳位电压:17V
    当电路出现浪涌时,器件快速击穿并将电压钳位在17V以内,这是后级元器件可承受的安全电压上限,避免过压击穿。
  3. 峰值脉冲电流(Ipp):30A
    器件能承受的最大瞬态浪涌电流(10/1000μs波形下),可有效应对静电放电(ESD)、感应雷击、电源瞬变等常见浪涌源。
  4. 峰值脉冲功率(Ppp):500W@10/1000μs
    浪涌功率耐受能力,10/1000μs是行业标准脉冲波形(上升时间10μs,下降至峰值50%的时间1000μs),覆盖大部分实际应用场景的浪涌特性。
  5. 击穿电压:11.1V(典型值)
    反向偏置下器件开始导通的典型电压,介于Vrwm(10V)与钳位电压(17V)之间,确保浪涌来临时快速响应。
  6. 反向漏电流(Ir):3μA
    正常工作时的反向漏电流,数值极小,不会增加系统功耗,对低功耗电路友好。

三、机械与环境适应性

  1. 封装形式:DO-15(轴向引线封装)
    采用标准化轴向引线封装,引脚间距、尺寸符合行业规范,便于PCB布线与插件焊接,适合批量生产。
  2. 工作温度范围:-55℃~+150℃
    宽温范围覆盖工业级、汽车级应用场景,可在极端温度环境下稳定工作(如户外通信设备、汽车发动机舱附近)。

四、品牌与可靠性优势

SA10CA/B由台湾君耀(Brightking)生产,君耀是全球知名的过压防护器件厂商,产品具备:

  • 一致性好:批量生产的参数偏差小,避免因器件差异导致防护性能不稳定;
  • 可靠性高:通过严格的可靠性测试(如温度循环、湿度老化),符合工业级、汽车级标准;
  • 供货稳定:具备成熟的产能与供应链,可满足中大规模应用需求。

五、典型应用场景

SA10CA/B的参数特性使其适配多种低电压过压防护场景:

  1. 通信设备:如10V供电的以太网接口、RS485/RS232通信端口防护;
  2. 工业控制:PLC的数字输入/输出端口、传感器(如温度、压力传感器)的过压防护;
  3. 汽车电子:12V系统中的低电压子模块(如车身控制模块的传感器接口)防护;
  4. 消费电子:部分10V供电的小型设备(如智能穿戴、便携医疗设备)的电源端口防护。

六、选型与使用注意事项

  1. 参数匹配:被保护电路的工作电压需≤10V(Vrwm),浪涌电流需≤30A(Ipp),避免器件过载;
  2. 安装方式:需并联在被保护电路的电源端或信号端,布线应尽量短(减少寄生电感,提升响应速度);
  3. 焊接要求:DO-15封装的焊接温度需控制在260℃以内,焊接时间≤5秒,避免损坏器件;
  4. 极性确认:因是双向TVS,无需区分正负极,安装更便捷。

综上,SA10CA/B是一款性能均衡、适配性强的双向TVS器件,在低电压电路的过压防护中具备显著优势,可有效提升系统的可靠性与抗干扰能力。

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.
