IC = f(VCE) Curve Shape Figure 2. Basic Energy Test Circuit By design, the BU323Z has a built−in avalanche diode and a special high voltage driving circuit. During an auto−protect cycle, the transistor is turned on again as soon as a voltage, determined by the zener threshold and the network, is reached. This prevents the transistor from going into a Reverse Bias Operating limit condition. Therefore, the device will have an extended safe operating area and will always appear to be in “FBSOA.” Because of the built−in zener and associated network, the IC = f(VCE) curve exhibits an unfamiliar shape compared to standard products as shown in Figure 1. The bias parameters, VCLAMP, IB1, VBE(off), IB2, IC, and the inductance, are applied according to the Device Under Test (DUT) specifications. VCE and IC are monitored by the test system while making sure the load line remains within the limits as described in Figure 4. Note: All BU323Z ignition devices are 100% energy tested, per the test circuit and criteria described in Figures 2 and 4, to the minimum guaranteed repetitive energy, as specified in the device parameter section. The device can sustain this energy on a repetitive basis without degrading any of the specified electrical characteristics of the devices. The units under test are kept functional during the complete test sequence for the test conditions described: IC(peak) = 7.0 A, ICH = 5.0 A, ICL = 100 mA, IB = 100 mA, RBE = 100 Ω, Vgate = 280 V, L = 8.0 mH 10 IC, COLLECTOR CURRENT (AMPS) 300μs 1 1ms TC = 25°C 10ms 250ms 0.1 0.01 0.001 10 THERMAL LIMIT SECOND BREAKDOWN LIMIT CURVES APPLY BELOW RATED VCEO 100 340V VCE, COLLECTOR-EMITTER VOLTAGE (VOLTS) Figure 3. Forward Bias Safe Operating Area http://onsemi.com 3 1000 BU323Z IC The shaded area represents the amount of energy the device can sustain, under given DC biases (IC/IB/VBE(off)/ RBE), without an external clamp; see the test schematic diagram, Figure 2. The transistor PASSES the Energy test if, for the inductive load and ICPEAK/IB/VBE(off) biases, the VCE remains outside the shaded area and greater than the VGATE minimum limit, Figure 4a.

This assures that hot spots and uncontrolled avalanche are not being generated in the die, and the transistor is not damaged, thus enabling the sustained energy level required.
