IPS0551T Equivalent & Substitute Parts

Part Overview

The IPS0551T is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, classified as a Power Switch/Driver with 1:1 N-Channel configuration. This component functions as a low-side N-channel switch rated for 35A maximum output current in a SUPER-220™ (TO-273AA) through-hole package. The product is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar switching capabilities.

Substitute Part Grouping Explanation

The substitute parts identified for the IPS0551T are STMicroelectronics thyristor devices: AVS08CB and AVS10CB. These components are classified as TRIACs (Triode for Alternating Current) with internal trigger functionality, representing a different device category than the original N-channel power switch. Substitution logic is based on the following criteria provided in the input parameters:

• Through-hole mounting configuration (TO-220 package family)
• Active product status with current manufacturing availability
• RoHS3 compliance for modern supply chain requirements
• Voltage and current handling capabilities within operational ranges

The AVS08CB operates at 500V off-state voltage with 5A on-state current maximum. The AVS10CB operates at 600V off-state voltage with 8A on-state current maximum. Both devices feature internally triggered TRIAC configuration and single-channel output.

Parameter Comparison

Engineering Selection Recommendations

Selection between AVS08CB and AVS10CB should be based on system voltage and current requirements:

The AVS08CB is suitable for applications requiring 500V off-state voltage rating with maximum 5A on-state current. This device operates across -10°C to 125°C temperature range and carries ROHS3 compliance certification.

The AVS10CB is suitable for applications requiring 600V off-state voltage rating with maximum 8A on-state current. This device operates across 0°C to 125°C temperature range and carries ROHS3 compliance certification.

Both substitute parts are manufactured by STMicroelectronics with active product status, ensuring ongoing availability and supply chain support. Both devices meet REACH compliance requirements and carry EAR99 export classification identical to the original IPS0551T.

Frequently Asked Questions (FAQ)

Q: Why are the substitute parts classified as Thyristors rather than Power Switches?

A: The substitute parts provided (AVS08CB and AVS10CB) are TRIAC devices, which represent a different semiconductor category than the original N-channel power switch. Substitution is based on the parameters explicitly provided in the input specification.

Q: Are the TO-220-3 packages compatible with the original TO-273AA package?

A: Both package types are through-hole mounted variants within the TO-220 family. Physical compatibility requires verification of pin configuration and PCB layout specifications for your specific application.

Q: What is the temperature operating range difference between the main part and substitutes?

A: The IPS0551T operates from -40°C to 150°C (TJ), while AVS08CB operates from -10°C to 125°C (TJ) and AVS10CB operates from 0°C to 125°C (TJ). Applications requiring extended low-temperature operation below -10°C may not be suitable for these substitutes.

Q: Do the substitute parts meet modern compliance requirements?

A: Both AVS08CB and AVS10CB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original IPS0551T is listed as RoHS non-compliant.

Q: What are the current handling differences?

A: The IPS0551T is rated for 35A maximum output current. The AVS08CB is rated for 5A on-state current (RMS) maximum, and the AVS10CB is rated for 8A on-state current (RMS) maximum. Applications requiring currents above 8A cannot use these substitutes.
