The thermal mass connected to the tie point is normally large enough so that it will not significantly respond to heat surges generated in the diode as a result of pulsed operation once steady−state conditions are achieved. Using the measured value of TL, the junction temperature may be determined by: TJ = TL + DTJL ZqJL(t) = RqJL • r(t) DTJL = Ppk RqJL[r(t)] where: DTJL = the increase in junction temperature above the lead temperature r(t) = normalized value of transient thermal resistance at time, t from this figure. For example, r(tp) = normalized value of transient resistance at time tp. TIME tp Figure 6. Typical Breakover Voltage Figure 7. Typical Holding Current Figure 8.
