What are the differences between electrostatic diodes and TVS diodes?

The differences between electrostatic diodes and TVS diodes in circuits are reflected in their power, packaging, and applications.
1、 Power
The working principle of an electrostatic diode is the same as that of an electrostatic diode, but there is still a significant difference in power between the two. ESD diodes typically have power levels of 50W, 90W, 100W, 200W, 350W, 400W, 450W, 500W, etc. The power of ESD diodes is generally low. The power of TVS diodes includes 200W, 400W, 500W, 600W, 1000W, 1500W, 3000W, 3600W, 4600W, 5000W, 6000W, 6600W, 15000W, 30000W, and even ultra-high power TVS diodes.
2、 Encapsulation
The packaging of electrostatic diodes and TVS diodes is completely different. ESD diode packages include SOT-23, SOD-523, DFN0603-D, DFN1006-2L, SOD-323F, DFN-2L, SOD-323, SOT-353, DFN0603-2L, DFN2010-8L, and so on. TVS diode packages include DO-218AB, SMA/DO-214AC, SMB/DO-214AA, SMC/DO-214AB, SOD-123, DO-41, DO-15, DO-201, R-6/P600, NA, and more.
3、 Application
The function of ESD diode is anti-static, and the prerequisite for electrostatic protection requires its capacitance value to be sufficiently low, generally between 1PF-3.5PF, mainly used for board level protection. The function of TVS diode is to prevent surge overvoltage, mainly used for primary and secondary protection. When choosing ESD electrostatic protection diodes, more emphasis is placed on ESD rating (HBM/MM), IEC61000-4-2 LEVEL, and junction capacitance. When choosing TVS transient suppression diodes, more emphasis is placed on breakdown voltage, clamping voltage, operating voltage, packaging, and power.
