Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IR21365SPBF is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Channel Type: 3-Phase operation
• Number of Drivers: 6 drivers
• Gate Type: IGBT and N-Channel MOSFET compatibility
• Package / Case: 28-SOIC form factor (0.295", 7.50mm Width)
• Input Type: Inverting logic
• High Side Voltage - Max (Bootstrap): 600V rating
• Operating Temperature Range: -40°C to 150°C (TJ)
• Compliance Standards: ROHS3 and REACH requirements

The IR2136SPBF qualifies as a substitute based on matching all critical parameters. Minor variations in supply voltage range (10V ~ 20V versus 12V ~ 20V) and product status do not affect functional compatibility in applications designed for the IR21365SPBF.

Parameter Comparison

Engineering Selection Recommendations

The IR2136SPBF serves as the direct substitute for the IR21365SPBF in applications requiring half-bridge gate driver functionality for 3-phase IGBT and N-Channel MOSFET systems. Both devices maintain identical electrical performance characteristics, including output current ratings, timing specifications, and thermal operating ranges. Both parts comply with ROHS3 and REACH regulatory requirements.

The IR2136SPBF offers expanded supply voltage compatibility (10V minimum versus 12V minimum), providing additional operational flexibility in systems with lower supply rails. The identical 28-SOIC package ensures direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the IR2136SPBF replace the IR21365SPBF in existing designs?

A: Yes. The IR2136SPBF maintains functional equivalence across all critical parameters: half-bridge configuration, 3-phase channel type, 6-driver count, identical gate type support, matching output current ratings, identical timing specifications, and equivalent thermal operating range. The 28-SOIC package is identical, enabling direct substitution without PCB modifications.

Q: What is the difference in supply voltage range between these parts?

A: The IR21365SPBF operates from 12V to 20V, while the IR2136SPBF operates from 10V to 20V. The IR2136SPBF supports lower minimum supply voltages, making it suitable for applications with reduced supply rails. Both maintain identical performance within their respective operating ranges.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the IR21365SPBF and IR2136SPBF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the product status difference?

A: The IR21365SPBF is classified as obsolete, indicating discontinued manufacturing and limited availability. The IR2136SPBF is classified as "Not For New Designs," indicating it remains available but is not recommended for new product development. For ongoing support of existing systems using the IR21365SPBF, the IR2136SPBF provides functional continuity.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 28-SOIC package with identical dimensions of 0.295" × 7.50mm width, ensuring direct PCB compatibility without layout modifications.
