IR2114SSPBF Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IR2114SSPBF is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and MOSFET power switches in half-bridge configurations. This device operates with independent channels and provides non-inverting logic inputs. The IR2114SSPBF is classified as Not For New Designs, making identification of active equivalent parts essential for ongoing production and maintenance applications. Substitute parts must maintain functional compatibility while meeting current product availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2114SSPBF is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology
• Number of Drivers: 2 independent channels
• Gate Type: IGBT compatibility
• Voltage - Supply: 11.5V ~ 20V operating range
• Logic Voltage Levels: VIL 0.8V, VIH 2V
• Current - Peak Output: 2A source, 3A sink capability
• Input Type: Non-Inverting logic
• Package / Case: 24-SSOP form factor
• Operating Temperature Range: -40°C ~ 150°C (TJ)

The IR2214SSTRPBF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in High Side Voltage rating (1200V vs. 600V) and product status do not preclude substitution when the application does not require the lower bootstrap voltage specification of the original part.

Parameter Comparison

Engineering Selection Recommendations

The IR2214SSTRPBF is the qualified substitute for the IR2114SSPBF based on the following engineering criteria:

All critical electrical parameters match exactly: supply voltage range, logic voltage thresholds, peak output current ratings, rise/fall times, and operating temperature range remain identical. The package form factor and mounting type are identical, ensuring direct PCB compatibility without layout modifications.

The IR2214SSTRPBF carries Active product status, whereas the IR2114SSPBF is designated Not For New Designs. This status difference reflects manufacturing lifecycle positioning and does not indicate functional incompatibility. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements.

The IR2214SSTRPBF features a higher High Side Voltage rating (1200V vs. 600V bootstrap voltage). This represents an enhanced specification that does not restrict substitution; applications designed for the 600V specification will operate within the 1200V-rated device without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the IR2214SSTRPBF directly replace the IR2114SSPBF on existing PCBs?

A: Yes. Both devices use identical 24-SSOP packaging with matching pin assignments and electrical interfaces. No PCB modifications are required for substitution.

Q: What is the significance of the different High Side Voltage ratings (600V vs. 1200V)?

A: The High Side Voltage specification defines the maximum bootstrap voltage the gate driver can withstand. The IR2214SSTRPBF's 1200V rating exceeds the IR2114SSPBF's 600V rating. Applications designed for 600V operation will function correctly with the higher-rated substitute.

Q: Why is the IR2114SSPBF marked as Not For New Designs?

A: This designation indicates the part has reached end-of-life status in Infineon's product portfolio. The IR2214SSTRPBF represents the active equivalent for new and ongoing production applications.

Q: Are the logic voltage thresholds identical between these parts?

A: Yes. Both the IR2114SSPBF and IR2214SSTRPBF operate with VIL = 0.8V and VIH = 2V, ensuring identical input signal compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant and REACH Unaffected, satisfying equivalent regulatory requirements.

Q: What is the difference between Tube and Cut Tape packaging options?

A: Tube packaging (IR2114SSPBF) and Cut Tape & Digi-Reel packaging (IR2214SSTRPBF) represent different distribution formats. Both contain identical die and electrical specifications. Selection depends on procurement volume and handling requirements.
