NPN Silicon Power Darlington High Voltage Autoprotected

The BU323Z is a planar, monolithic, high–voltage power Darlington with a built–in active zener clamping circuit. This device is specifically designed for unclamped, inductive applications such as Electronic Ignition, Switching Regulators and Motor Control, and exhibit the following main features:

• Integrated High–Voltage Active Clamp
• Tight Clamping Voltage Window (350 V to 450 V) Guaranteed Over the –40°C to +125°C Temperature Range
• Clamping Energy Capability 100% Tested in a Live Ignition Circuit
• High DC Current Gain/Low Saturation Voltages Specified Over Full Temperature Range
• Design Guarantees Operation in SOA at All Times
• Offered in Plastic SOT–93/TO–218 Type or TO–220 Packages
