Even in severe bonding systems used in the construction of power rectifiers. applications, such as catch diodes for switching regulators and In this stress test, the case of the device is not heat sunk. Full rated output rectifiers for high frequency square wave inverters, these forward current is supplied to force a case temperature increase at devices switch many times faster than the fastest associated least 75C, at which time, the current is removed and the case transistors. Thus, the stresses on and powers dissipated in the allowed to cool. The cycle is repeated a minimum of 5,000 times to switching transistors are substantially less than when using other simulate equipment being turned on and off. Extended power cycling rectifiers. tests demonstrate a product capability in excess of 25,000 cycles.
