MGP15N40CL

Overview

The MGP15N40CL is a logic level N-channel Insulated Gate Bipolar Transistor (IGBT) designed for high voltage and high current switching applications. It features monolithic circuitry integrating ESD protection and an over-voltage clamped gate-collector circuit. The device offers a collector-emitter voltage of 440 VDC, a continuous collector current of 15 ADC at 25°C, and a pulsed current capability up to 50 AAC. It operates within a junction temperature range of -55°C to 175°C and provides low saturation voltage with a threshold voltage suitable for direct interface to logic or microprocessor devices.

Feature Summary

• Integrates monolithic ESD and over-voltage clamped protection for inductive coil drivers
• Features temperature compensated gate-collector voltage clamp to limit stress on the load
• Includes integrated ESD diode protection and low threshold voltage for logic interfacing
• Offers optional internal gate resistor configuration

Applications

• Ignition systems including Coil-On-Plug and Distributorless Ignition Systems
• Direct Fuel Injection circuits
• High voltage and high current switching applications requiring inductive coil driving

Procurement Notes

Verify the specific package variant required, as the MGP15N40CL designation corresponds to the TO-220AB package. Confirm if lead-free compliance is necessary, which utilizes the suffix 'G' (MGP15N40CLG). Ensure the ordering information matches the desired shipping quantity format, such as rails for through-hole packages. Cross-reference the datasheet revision to confirm electrical characteristics align with the manufacturing batch.

Selection Notes

Select this component when designing ignition or fuel injection circuits that require robust gate protection against transients. The low threshold voltage facilitates drive from standard logic levels without additional level shifting. Consider the thermal resistance values for heatsinking requirements, noting the difference between junction-to-case and junction-to-ambient ratings. Evaluate the single-pulse avalanche energy capabilities if the application involves significant inductive kickback.

Part Context

This device belongs to the MGP/MGB series of preferred IGBTs from onsemi, specifically engineered for automotive ignition environments. It shares functional similarities with the MGB15N40CL but differs in packaging, with the MGP variant utilizing the TO-220AB form factor. The series emphasizes reliability in high-stress inductive loads common in modern engine management systems.

Replacement Considerations

The MGB15N40CL serves as a pin-compatible alternative available in the D2PAK surface-mount package. Verify that the thermal dissipation characteristics of the replacement package meet the system's cooling requirements. Ensure that any substitute maintains the same logic-level gate threshold and integrated protection features to preserve circuit compatibility.
