The NGB18N40CLBT4G is a logic-level insulated gate bipolar transistor (IGBT) from onsemi, designed for high-voltage and high-current switching applications. It features monolithic circuitry integrating ESD and over-voltage clamped protection. The device operates with a collector-emitter voltage of 430 VDC and supports continuous collector currents up to 18 A at 25°C, with pulsed capability reaching 50 A. Total power dissipation is rated at 115 W at 25°C. It utilizes a D2PAK surface-mount package (CASE 418B) and functions within an operating temperature range of -55°C to +175°C.
Verify the component status as discontinued by checking official manufacturer documentation. Confirm that the 'G' suffix indicates a lead-free package compliant with relevant environmental standards. Ensure the ordering information matches the specific tape and reel specifications required for automated assembly processes.
Select this component for applications requiring robust unclamped inductive switching energy per area. Consider the low saturation voltage and high pulsed current capability when designing circuits for harsh environments. Verify thermal management requirements against the junction-to-case thermal resistance values provided in the datasheet.
This IGBT belongs to the NGB18N series, which focuses on ignition-specific performance. It is part of onsemi's portfolio of power semiconductors optimized for automotive and industrial switching loads. The D2PAK package provides a compact solution for surface-mount technology implementations.
