Functional Architecture: Half-bridge configuration with synchronous dual N-channel MOSFET gate driving capability and RC input circuit topology.

Electrical Specifications: Supply voltage range of 10V to 15.6V, bootstrap voltage rating of 600V, and timing characteristics (rise/fall times of 80ns and 45ns respectively).

Physical Form Factor: 8-SOIC surface mount package with 0.154" (3.90mm) width specification.

Regulatory Compliance: ROHS3 compliance and MSL 2 rating for moisture sensitivity.

The IR25603STRPBF meets all substitution criteria across these parameters while offering enhanced operating temperature range and active product status.

Parameter Comparison

Engineering Selection Recommendations

The IR25603STRPBF qualifies as a direct substitute for the IR2153STRPBF based on functional equivalence across all critical electrical and mechanical parameters. Both devices share identical supply voltage specifications, bootstrap voltage ratings, timing characteristics, and package form factors.

The IR25603STRPBF offers two significant advantages: active product status from Infineon Technologies ensures ongoing availability and technical support, and an extended operating temperature range (-40°C to 150°C versus -40°C to 125°C) provides additional thermal margin for demanding applications. Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

Selection of the IR25603STRPBF is appropriate for applications requiring long-term supply chain stability and enhanced thermal performance within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: What makes the IR25603STRPBF a valid substitute for the IR2153STRPBF?

A: Both devices implement identical half-bridge gate driver architecture with synchronous dual N-channel MOSFET configuration, RC input circuit topology, 10V to 15.6V supply voltage range, 600V bootstrap voltage rating, and 8-SOIC package form factor.
