P4SMA Series 瞬态抑制二极管（P4SMA Series TVS Diodes）
2023-04-23
●概述:
■瞬态抑制二极管 (TVS) 是一种电路保护元件，它可以削弱或过滤突增的瞬态电压(过压)，在浪涌到来瞬间几纳秒时间内发生雪崩击穿，将浪涌电流引至接地端，并将电压箝位在安全范围内，从而实现了高效能的电压保护。
●Description:
■Transient Voltage Suppressor (TVS) is a circuit protection component that either attenuates (reduces) or filters a transient voltage spike (overvoltage), TVS diodes provide critical protection by going into avalanche breakdown within no more than a few nanoseconds after a strike, clamping the transient voltage, and routing its current to the ground
●特性:
■浪涌电阻
■优异的箝位性能
■小型化紧凑封装，内部结构去应力设计
■12 V以上电压规格对应漏电典型值低于1.0 μA
■重复率0.01% 的10/1000 μS 波形对应峰值脉冲功率400 W
■表贴应用，节约空间
■典型的故障模式为电压或电流超过额定而导致的短路
■IEC 61000-4-2 ESD 30 kV(空气)，30 kV(接触)
■数据线EFT保护符合IEC 61000-4-4
■快速响应时间
■玻璃钝化保护或平面芯片(< 10 V ）
■回流焊高温保证:260 °C/30 s
■温度系数典型值0.1%
■密封材料阻燃等级V-0
■湿度敏感等级符合MSL 等级1
■引脚镀雾锡
■无卤素，符合RoHS要求
■无铅E3：二级互连引线无铅，端子镀锡(Sn) (IPC/JEDEC J-STD -609A.01)
●FEATURES:
■Low incremental surge resistance
■Excellent clamping capability
■Low profile package with built-in strain relief
■Typical IR less than 1.0 μA above 12 V
■400 W peak pulse power capability with a 10/1000 μS Wave-form, repetition rate (duty cycle): 0.01%
■For surface mounted applications to optimize board space
■Typical failure mode is short from over-specified voltage or current
■IEC 61000-4-2 ESD 30 kV (Air), 30 kV (Contact)
■EFT protection of data lines in accordance with IEC 61000-4-4
■Very fast response time
■Glass passivated chip junction or Planar chip (< 10 V )
■High temperature to reflow soldering guaranteed: 260 °C/40sec
■VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25))(αT:Temperature Coefficient, typical value is 0.1%)
■Plastic package is flammability rated V-0 per Underwriters Laboratories
■Meet MSL level1, per J-STD-020
■Matte tin lead–free plated
■Halogen free and RoHS compliant
■Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD-609A.01)
