IR2136PBF Equivalent & Substitute Parts

Part Overview

The IR2136PBF is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in 3-phase applications. This component operates with a supply voltage range of 10V to 20V and features a maximum bootstrap voltage of 600V, making it suitable for power management and motor control applications.

The IR2136PBF is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for systems utilizing this gate driver topology.

Substitute Part Grouping Explanation

Substitution of the IR2136PBF is determined by functional equivalence across the following critical parameters:

• Driven Configuration & Channel Type: Half-bridge, 3-phase topology with 6 drivers
• Gate Type Compatibility: IGBT and N-Channel MOSFET support
• Electrical Specifications: Supply voltage (10V ~ 20V), logic levels (0.8V / 3V), peak output current (200mA source / 350mA sink), bootstrap voltage (600V maximum), and switching characteristics (125ns rise / 50ns fall time)
• Input Polarity: Inverting input configuration
• Operating Temperature Range: -40°C to 150°C junction temperature
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The IR2136STRPBF maintains identical electrical and functional specifications to the IR2136PBF. The primary difference is packaging format: the original part uses through-hole 28-DIP mounting, while the substitute employs surface-mount 28-SOIC technology. Both parts share the same base product number (IR2136) and are manufactured by Infineon Technologies.

Parameter Comparison

Engineering Selection Recommendations

The IR2136STRPBF is the active-status equivalent substitute for the obsolete IR2136PBF. Both components are manufactured by Infineon Technologies and maintain identical electrical specifications, functional behavior, and regulatory compliance (ROHS3 compliant, REACH unaffected).

Selection between these parts is determined by PCB assembly requirements:

• IR2136PBF (Through-Hole 28-DIP): Suitable for through-hole assembly processes and legacy board designs. Obsolete status limits future availability.
• IR2136STRPBF (Surface-Mount 28-SOIC): Recommended for new designs and ongoing production. Active product status ensures long-term supply chain availability. Surface-mount packaging enables higher-density PCB layouts and automated assembly processes.

The IR2136STRPBF carries a higher moisture sensitivity level (MSL 3 vs. MSL 1), requiring controlled storage conditions (168-hour maximum exposure at specified humidity levels) compared to the unlimited storage capability of the through-hole variant.

Frequently Asked Questions (FAQ)

Q: Can the IR2136STRPBF directly replace the IR2136PBF in existing designs?

A: Electrical and functional specifications are identical. PCB layout and assembly process modifications are required due to packaging differences (surface-mount 28-SOIC versus through-hole 28-DIP). Pin configuration and signal functionality remain unchanged.

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

A: The primary differences are mounting technology (surface-mount versus through-hole), package dimensions, product status (active versus obsolete), and moisture sensitivity level (MSL 3 versus MSL 1). All electrical parameters, gate driver specifications, and operating characteristics are identical.

Q: Why is the IR2136PBF classified as obsolete?

A: The IR2136PBF is an older through-hole package variant. Infineon Technologies has transitioned to the surface-mount IR2136STRPBF as the active product line, reflecting industry-wide movement toward compact, automated assembly technologies.

Q: Are there any compatibility concerns when switching from IR2136PBF to IR2136STRPBF?

A: No electrical or functional compatibility concerns exist. The components are functionally equivalent. Design changes are limited to PCB layout modifications to accommodate the different package footprint and assembly process adjustments for surface-mount technology.

Q: What is the moisture sensitivity level (MSL) difference, and why does it matter?

A: The IR2136PBF has MSL 1 (unlimited storage), while the IR2136STRPBF has MSL 3 (168-hour maximum exposure at specified humidity). For the IR2136STRPBF, storage conditions must be controlled to prevent moisture absorption, which can affect soldering reliability. Proper handling and baking procedures are required before assembly.

Q: Is the IR2136STRPBF suitable for new product designs?

A: Yes. The IR2136STRPBF is the active product variant and is recommended for all new designs. Active status ensures ongoing manufacturer support, long-term availability, and compliance with current regulatory standards.
