ØTrend: Chip size decreases to minimum
üGate thickness and chip size (channel length) decreases
üMaximum gate voltage decreases (e.g. for CMOS090<1.5V static)
üNew processes are optimized for area and performance, NOT for ESD performance!
ØImpact:
üVery ESD sensitive ICs which burn at low clamping voltages
üAdditional board level ESD protection for external interfaces becomes a must!

Why Use External ESD Protection Devices?
§ Integrating simple protection on complex ICs is expensive and it is low level
§ IC gate oxides are thinner and are more vulnerable to ESD events
§ Protection circuits are most effective when placed farther from the major ICs and closer to the connectors
§ Designing in ESD/EMI protection up front is cost effective…..
• Avoid re-designs after a failure during certification tests
• Avoid cost of returned product from end customers

TVS vs. MOVTVS vs. MOV-- ESD PulseESD Pulse
Input: 8KV ESD Pulse, IEC 61000-4-2
Output: Varistor, VA-C1005-5R5E
Output: 6.1V TVS
High clamping Voltage (35V)
Low clamping Voltage (7V)
Conclusion: TVS diodes clamp surges at a lower voltage than a MOV!

ESD/Surge ConclusionsESD/Surge Conclusions
n IC’s must be protected because most of them cannot withstand ESD conditions higher than 2 kV
n PCB lay-out is critical to improve TVS protection andreduce parasitic effects (V = L di/dt)
n Avalanche TVS diodes have several technicaladvantages over competitive TVS devices
l Low clamping voltagel Low breakdown voltagel No change in electrical characteristics after ESD/surge event

Attenuation will decrease back up to 10dB(ie 3:1) when 3*2*[π]*f* LP = R If R = 33 ohm, this will occur when fC = 1.5GHz
The effect of parasitic inductance LP becomes noticeable when ZLp approaches ZCi.e. when 2*[π]*f* LP = 1/(2*[π]*f*C) If C = 50pF, and say LP = 1nH, fC = 500MHzOr for CSP, 2 bumps = 100pH, fC = 5GHz
