How do you find the leakage current?
Using the formula I = 377VC, find the leakage current I (in amps) by multiplying the voltage that your hipot test is conducted at (V) by the capacitance you measured between line and ground (C), and multiplying that product by 377. This will give you the anticipated leakage current I (in amps).
How is PSU leakage current measured?
The leakage current is measured by applying a fixed, high voltage DC and by measuring the leakage current flowing through the shunt. The high voltage DC is generated using an onboard power supply based on a flyback topology, which takes a wide range of DC input voltage from 150-V DC to 800-V DC.
What’s the difference between TLP and TLP voltage?
The drawn red curve with symbols is the device I-V characteristic: TLP current (left y-axis) vs. TLP voltage (bottom x-axis). The red dashed curve is the development of the DC leakage current (top x-axis) vs. the TLP current (left y-axis).
How does transmission line pulse ( TLP ) testing work?
Transmission Line Pulse (TLP) testing is a method to characterize the behavior of components and circuits under ESD stress conditions [1], [4]. In contrast to classical component level Electrostatic Discharge (ESD) testing methods, like Human Body Model (HBM) [2] and Charged Device Model (CDM) [3], TLP provides more than a pass/fail result.

How is TLP used in electrostatic discharge testing?
In contrast to classical component level Electrostatic Discharge (ESD) testing methods, like Human Body Model (HBM) [2] and Charged Device Model (CDM) [3], TLP provides more than a pass/fail result. It actually provides a quasi-static I-V characteristic that describes the behavior of the Device Under Test (DUT).
