5.0SMDJ150A 单向TVS二极管

过压保护器件之一瞬变TVS二极管，是一种高效限压型保护器件，反应速度快（PS级）、瞬态功率大、钳位电压易控制、击穿电压偏差小、小体积、高可靠性，广泛应用于汽车电子、智能家居、照明、仪器仪表、消费电子、办公用品、医疗器械、新能源领域等等。在10/1000us下，瞬变TVS二极管功率能从200W做到30000W，甚至更高；工作电压低至3.3V，高达600V，甚至更高；封装多样，有贴片和直插之分。那么，工作电压150V，功率5000W，SMC封装的瞬变TVS二极管，有哪些型号呢？

 

 

查看东沃电子瞬变TVS二极管产品选型手册可知，能满足“工作电压150V、功率5000W、SMC封装”这三个条件的瞬变TVS二极管型号有：5.0SMDJ150A、5.0SMDJ150CA，其参数详情如下：

最小击穿电压Breakdown Voltage：167.00V

最大击穿电压Breakdown Voltage：185.00V

最大反向电流Maximum Reverse Leakage：5uA

工作电压Working Peak Reverse Voltage：150.00V

峰值脉冲电流Maximum Reverse Surge Current：20.58A

最大钳位电压Maximum Clamping Voltage：243.00V

峰值脉冲功率Peak Pulse Power：5000W

封装Package：SMC (DO-214AB)

丝印标识Marking Code：5PHM (5.0SMDJ150A), 5BHM (5.0SMDJ150CA)

 

 

通过对比发现，瞬变TVS二极管5.0SMDJ150A和5.0SMDJ150CA区别在于前者是单向，后者是双向，在应用方面也有差异，其它参数都是一样的。一般而言，在直流电路中，选用单向瞬变TVS二极管，在交流电路中，选用双向瞬变TVS二极管，具体的话，建议咨询东沃电子产品工程师！
