IXDD408PI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDD408PI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT, N-Channel, and P-Channel MOSFET devices in power management applications. This component operates with a non-inverting input configuration and is packaged in an 8-DIP through-hole format. The IXDD408PI is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IXDD408PI is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Criteria:

• Driven Configuration: Low-Side (must match exactly)
• Channel Type: Single (must match exactly)
• Number of Drivers: 1 (must match exactly)
• Gate Type: IGBT, N-Channel, P-Channel MOSFET (must match exactly)
• Input Type: Non-Inverting (must match exactly)
• Package / Case: 8-DIP (0.300", 7.62mm) (must match exactly)
• Mounting Type: Through Hole (must match exactly)

Allowable Parameter Variations for Substitution:

• Voltage - Supply: May be equal to or exceed the original specification
• Logic Voltage - VIL, VIH: May be equal to or more permissive than the original
• Current - Peak Output (Source, Sink): May be equal to or exceed the original specification
• Rise / Fall Time (Typ): May be equal to or faster than the original
• Operating Temperature: May be equal to or exceed the original range

The IXDD609PI meets all mandatory compatibility criteria and demonstrates allowable parameter enhancements across supply voltage, output current, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The IXDD609PI is a direct functional substitute for the obsolete IXDD408PI based on matching driven configuration, channel topology, gate type compatibility, and physical package specifications. The IXDD609PI is currently in active production status, ensuring long-term availability and supply chain continuity.

The IXDD609PI provides enhanced electrical performance characteristics: extended supply voltage range (4.5V ~ 35V versus 4.5V ~ 25V), increased peak output current capability (9A versus 8A), and expanded operating temperature range (-55°C ~ 150°C versus -40°C ~ 150°C). These parameter enhancements are backward-compatible with applications designed for the IXDD408PI.

The IXDD609PI carries RoHS3 compliance certification and maintains REACH unaffected status, consistent with modern regulatory requirements. Both devices share identical 8-DIP through-hole packaging, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the IXDD609PI directly replace the IXDD408PI in existing designs?

A: Yes. The IXDD609PI maintains identical driven configuration (low-side), channel type (single), gate type support (IGBT, N-Channel, P-Channel MOSFET), input type (non-inverting), and 8-DIP through-hole package specifications. The substitute part provides equal or enhanced electrical performance across all critical parameters.

Q: What are the key differences between these two parts?

A: The IXDD609PI offers extended supply voltage range (35V maximum versus 25V), higher peak output current (9A versus 8A), and broader operating temperature range (-55°C to 150°C versus -40°C to 150°C). Rise time is slightly slower (22ns versus 14ns), while fall time remains identical at 15ns.

Q: Is the IXDD609PI available in the same package as the IXDD408PI?

A: Yes. Both parts use 8-DIP (0.300", 7.62mm) through-hole packaging with identical pinout and footprint compatibility.

Q: Why is the IXDD408PI listed as obsolete?

A: The IXDD408PI has been discontinued by IXYS. The IXDD609PI represents the active production equivalent, ensuring continued availability for new designs and legacy system support.

Q: Are there any compliance differences between these parts?

A: The IXDD609PI carries RoHS3 compliance certification, meeting current regulatory standards. Both parts maintain REACH unaffected status and share identical ECCN and HTSUS classifications.
