晶导微(JINGDAO) TVS 二极管 SMCJ45CA BFV SMC(DO-214AB) 双向参数资料详解

晶导微(JINGDAO) 是一家专注于半导体器件研发的公司,其产品线涵盖TVS二极管、肖特基二极管、整流二极管等多种类型。SMCJ45CA BFV SMC(DO-214AB) 是一款双向 TVS 二极管,专门用于保护电子设备免受瞬态电压的损坏。本文将深入分析该款 TVS 二极管的特性,并提供详细的参数资料。

# 一、产品概述

SMCJ45CA BFV SMC(DO-214AB) 是一款表面贴装型双向 TVS 二极管,采用 DO-214AB 封装,具备以下特性:

* 双向保护: 该器件能够同时承受正向和负向瞬态电压,为电子设备提供全面的保护。

* 高压钳位: 拥有 45V 的钳位电压,能够有效抑制瞬态电压,防止其对设备造成损坏。

* 快速响应: 响应时间短,能够快速响应瞬态电压,有效保护敏感元件。

* 高功率处理能力: 能够承受高功率瞬态冲击,确保设备在恶劣环境下的安全运行。

* 低漏电流: 漏电流小,保证设备在正常工作状态下的低功耗。

* 符合RoHS标准: 符合环境保护标准,符合环保要求。

# 二、主要参数

| 参数 | 符号 | 数值 | 单位 |

|---|---|---|---|

| 钳位电压 | Vclamp | 45 | V |

| 峰值脉冲功率 | Ppk | 200 | W |

| 反向漏电流 | Ir | 10 | μA |

| 电容 | C | 2 | pF |

| 工作温度 | Top | -55°C ~ +150°C | °C |

| 封装 | Package | DO-214AB | |

参数解读:

* 钳位电压 (Vclamp): 该参数指 TVS 二极管在承受瞬态电压时所能承受的最大电压,超过该电压,TVS 二极管将进入导通状态,将瞬态电压钳位至安全范围内。

* 峰值脉冲功率 (Ppk): 指 TVS 二极管所能承受的瞬态功率的最大值,该参数反映了 TVS 二极管的保护能力。

* 反向漏电流 (Ir): 指 TVS 二极管在反向偏置状态下的漏电流,该参数反映了 TVS 二极管的性能指标。

* 电容 (C): 指 TVS 二极管的寄生电容,该参数会影响电路的性能,需要在设计电路时进行考虑。

* 工作温度 (Top): 指 TVS 二极管能够正常工作的温度范围,该参数需要在实际应用中进行参考。

# 三、应用领域

SMCJ45CA BFV SMC(DO-214AB) 广泛应用于各种电子设备中,主要包括以下领域:

* 通信设备: 如基站、交换机、路由器等,可以有效保护设备免受雷击、静电放电等瞬态电压的损坏。

* 工业控制: 如PLC、伺服电机、传感器等,可以有效保护设备免受电源波动、电磁干扰等瞬态电压的损坏。

* 消费电子: 如手机、平板电脑、笔记本电脑等,可以有效保护设备免受静电放电、电源波动等瞬态电压的损坏。

* 汽车电子: 如车载导航、车载娱乐系统等,可以有效保护设备免受汽车电路的干扰、雷击等瞬态电压的损坏。

# 四、电路应用

电路原理:

TVS 二极管在电路中的作用是提供瞬态电压的保护。当瞬态电压超过其钳位电压时,TVS 二极管会迅速进入导通状态,将瞬态电压钳位至安全范围内,并将瞬态能量吸收,从而保护电路中的其他敏感元件。
