Analysis: Leiditech SMC24 replaces NXP PESD1CAN SMC24: IEC61000-4-2 (ESD) ±30kV (air), ±30kV (contact) Paskage:SOT-23 Vrwm: 24v IPP:8A VC:48V Double way, two roads protection Application: Protect CANBUS port Pin configuration as below: PESD1CAN: IEC 61000-4-2, level 4 (ESD) Paskage:SOT-23 Vrwm: 24v IPP:3A VC:70V Double way, two roads protection Application: Protect CANBUS port Pin configuration as below: To Judge the ESD protection device by checking into below parameters: 1. All can reach IEC 61000-4-2, level 4 (ESD) 2. Check the capacity of ESD anti-surge ( IPP), Thru the test 8/20us, SMC24 IPP is 8A, NXP’s IPP is 3A. 3. It would be fine if value difference is not big between VRWM,VB and VC. Leiditech SMC24 ‘s VC is 48V, NXP PESD1CAN’s IC is 70V To meet the market’s demand, Leiditeh will produce low IPP value to lower the cost. The IPP is 3A. Also, we will lower the VC to 33V. It is better than NXP’s 70V. Customer should compare and choose the one with better quality and lower price. Leiditech would do the best to support you.
