瞬态电压抑制器二极管（也称为瞬态抑制二极管——TVSDiode）专门用于保护电子电路，以防受到瞬变和过压的危害，例如：EFT（电气快速瞬变）以及ESD（静电放电）。瞬态抑制二极管是采用硅雪崩技术的器件，因其具有反应时间快（低钳位电压）、电容值较低和漏电流低等特点而被选用。以下是各ESD保护管常用型号和参数PARTNO#VRM(V)VRR(Min)(V)VC(V)CJ(pF)IR(μA)CurrentIPP@8/20ms(A)Power_@8/20us_(WATT)PackageLESD8D5.0CT5G55.618.6150.59.4174SOD882LESD8D3.3CT5G3.3514.125111.2158SOD882LESD8D5.0T5G56.212.36518.7107SOD882LESD8D3.3T5G3.3512.3802.58.7102SOD882LESD8D12T5G1213.323.73015.9140SOD882LESD8B5.0ST5G55.812.5151--SOD882LESD8L5.0CT5G55.412.90.51--SOD882LESD8L3.3CT5G3.34.8100.51--SOD882LESD8L5.0T5G55.49.80.51--SOD882LESD8L3.3T5G3.34.8120.51--SOD882LESD9D3.3T5G3.3510.4802.59.8102SOD-923LESD9D5.0T5G56.212.36518.7107SOD-923LESD9D12T5G1213.523.73015.9140SOD-923LESD9D3.3CT5G3.3514.125111.2150SOD-923LESD9L3.3CT5G3.34.8100.51--SOD923LESD9L3.3T5G3.34.8120.51--SOD-923LESD9D5.0CT5G55.618.61519.4150SOD-923LESD9B5.0ST5G55.812.5151--SOD-923LESD9L5.0CT5G55.412.90.51--SOD-923LESD9L5.0T5G55.49.80.51--SOD-923LESD7D3.3T5G3.3510.4802.59.8102SOD-723LESD7D5.0T5G56.212.36518.7107SOD-723LESD5Z2.5T1G2.5410.9145611200SOD-523LESD5Z3.3T1G3.3514.1105111.2200SOD-523LESD5L3.3T1G3.359.50.51--SOD523LESD5Z5.0T1G56.218.68019.4200SOD-523LESD5D5.0CT1G55.618.61519.4174SOD-523LESD5L5.0CT1G55.412.90.51--SOD-523LESD5L5.0T1G55.49.80.51--SOD-523LESD5Z6.0T1G66.820.57018.8200SOD-523LESD5Z7.0T1G77.522.76518.8200SOD-523LESD5Z12T1G1213.5255519.6200SOD-523LESD5Z5.0CT1G55.618.62519.4200SOD-523LESD3Z5.0T1G569.8350105350SOD-323LESD3Z5.0CMT1G55.611.62519.4174SOD-323LSD05T1G5614.53501024350SOD-323LSD12T1G1213.325150115350SOD-323LESDA5V3LT1G35.32202-300SOT-23LESDA6V1LT1G5.256.114020-300SOT-23LESDA14V2LT1G1214.2905-300SOT-23LESDA25VLT1G2425501-300SOT-23LGSOT05CLT1G569.82202017300SOT-23LGSOT12CLT1G1213.31990112300SOT-23LESD6V8T1G56.4401-75SC-89LESDA5VAW6T1G56.4101512.525SC-88LESDA6V1W6T1G56.1501-100SC-88LESD6A5V6W6T1G3.35.2451-75SC-88LESD6A6V8W6T1G56.4401-75SC-88LESDA6V1W5T1G56.1901-150SC-88ALESDA6V8AW5T1G4.36.4131211.620SC-88ALESDA12AW5T1G1214.6151-25SC-88ALRC099-04AT1G560.3515150TSOP-6LRC099-04BT1G560.3515150SC-88LRC099-04DT1G560.3515150DFN-10LRC099MC-04AT1G5615150TSOP-6LRC199-04AT1G560.715150TSOP-6LRC199-04BT1G560.715150SC-88LRC399-04AT1G560.8110300TSOP-6)
