Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2135STRPBF is determined by strict equivalence across the following critical parameters:

• Half-bridge driven configuration with 3-phase, 6-driver topology
• Gate drive capability for IGBT and N-Channel MOSFET devices
• Supply voltage range of 10V to 20V
• Logic threshold levels (VIL = 0.8V, VIH = 2.2V)
• Peak output current specifications (250mA source, 500mA sink)
• Inverting input logic
• Bootstrap voltage rating of 600V maximum
• Switching characteristics (90ns rise time, 40ns fall time)
• Maximum junction temperature of 125°C

The IR2135JTRPBF qualifies as a substitute based on identical electrical performance across all specified parameters. The primary difference is packaging format: the substitute uses a 44-PLCC (J-Lead) package with 32 leads, compared to the original 28-SOIC package. This packaging change requires PCB layout modification but does not affect functional compatibility.

Engineering Selection Recommendations

The IR2135JTRPBF is a direct functional substitute for the IR2135STRPBF based on identical electrical specifications across all critical gate driver parameters. The substitute part is classified as active product status, ensuring ongoing availability and supply chain support compared to the obsolete status of the original part.

Selection of the IR2135JTRPBF requires PCB redesign to accommodate the 44-PLCC package footprint in place of the original 28-SOIC package. Pin mapping and signal routing must be verified against the respective datasheets to ensure correct gate driver connections to the power stage.

Both parts maintain ROHS3 compliance and equivalent moisture sensitivity levels, supporting environmental and regulatory requirements for industrial and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the IR2135JTRPBF directly replace the IR2135STRPBF without circuit modification?

A: The IR2135JTRPBF provides identical electrical functionality and gate drive performance. However, the package change from 28-SOIC to 44-PLCC requires PCB layout modification. Pin assignments must be cross-referenced between datasheets to ensure correct signal routing to the gate driver inputs and outputs.

Q: What is the primary reason for substitution?

A: The IR2135STRPBF is classified as obsolete. The IR2135JTRPBF is an active product with equivalent electrical specifications, providing supply chain continuity and long-term availability.

Q: Are there differences in thermal performance between the two packages?

A: Thermal performance characteristics are not provided in the input parameters. Thermal analysis must be conducted using manufacturer datasheets and thermal modeling specific to each package type and application environment.

Q: Do both parts support the same gate drive voltage and current specifications?

A: Yes. Both parts operate with identical supply voltage (10V to 20V), logic thresholds (VIL = 0.8V, VIH = 2.2V), and peak output current (250mA source, 500mA sink). Bootstrap voltage rating and switching characteristics are also identical at 600V maximum and 90ns/40ns rise/fall times respectively.

Q: What compliance certifications apply to both parts?

A: The IR2135STRPBF is ROHS3 compliant with MSL 3 rating. The IR2135JTRPBF compliance status is not specified in the provided data and must be confirmed through the manufacturer datasheet.
