IRG4BC30S-STRLP IGBT Equivalent & Substitute Parts

Part Overview

The IRG4BC30S-STRLP is a 600V, 34A IGBT manufactured by Infineon Technologies in D2PAK surface mount packaging. This component is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. The part operates across an industrial temperature range of -55°C to 150°C and is suitable for switching applications requiring 100W maximum power dissipation. Substitute parts must maintain electrical compatibility within the 600V voltage class while accommodating variations in current rating, power handling, and thermal characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRG4BC30S-STRLP is determined by the following critical parameters:

Voltage Class: All substitute parts must maintain 600V collector-emitter breakdown voltage to ensure safe operation in the same circuit topology.

Current Rating: The main part specifies 34A maximum collector current. Substitute parts with equal or higher current ratings (30A minimum) are acceptable, as they provide equivalent or superior current handling capacity.

Power Dissipation: Maximum power rating of 100W establishes the thermal envelope. Substitute parts with equal or higher power ratings ensure thermal compatibility.

Mounting Technology: The main part uses surface mount D2PAK packaging. Parametric equivalents must use identical or compatible D2PAK packaging. Functional equivalents may use alternative through-hole packages (TO-220-3) when circuit board layout permits.

Gate Charge and Switching Characteristics: Gate charge (50nC) and switching delays (Td on/off) influence driver circuit design. Substitute parts with similar or lower gate charge reduce driver stress.

Product Status and Compliance: Active status parts with ROHS3 compliance and REACH unaffected designation ensure long-term availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

AUIRG4BC30SSTRL (Parametric Equivalent): This part is the direct parametric equivalent to the IRG4BC30S-STRLP. It maintains identical electrical specifications including 34A collector current, 1.6V Vce(on), 50nC gate charge, and 22ns/540ns switching delays. The primary difference is packaging format: AUIRG4BC30SSTRL is supplied in Tape & Reel (TR) format versus the original part's unspecified packaging. Both use D2PAK surface mount technology. AUIRG4BC30SSTRL carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. This part is the preferred direct replacement for the obsolete IRG4BC30S-STRLP in existing designs without circuit modification.

STGB19NC60KDT4 (MFR Recommended - STMicroelectronics): This STMicroelectronics part operates at 600V with 35A collector current, exceeding the main part's 34A rating by 1A. Power rating increases to 125W. The part uses D2PAK surface mount packaging, maintaining mechanical compatibility. Gate charge is 55nC, slightly higher than the 50nC specification. Switching characteristics differ: Td(on) is 30ns versus 22ns, and Td(off) is 105ns versus 540ns, indicating faster switching behavior. This part is suitable for applications where higher current capacity and improved switching speed provide design margin. Active product status and ROHS3 compliance confirm availability and regulatory compliance.

IGP15N60TXKSA1 (MFR Recommended - Infineon Technologies): This Infineon part represents a functional equivalent with different packaging and thermal characteristics. Operating voltage remains 600V, but collector current is 30A, below the main part's 34A specification. Power rating increases to 130W, and operating temperature range extends to 175°C maximum. The part uses TO-220-3 through-hole packaging rather than surface mount D2PAK, requiring circuit board redesign. Gate charge is 87nC, significantly higher than the 50nC specification, affecting driver circuit design. Switching delays are faster: 17ns/188ns. This part is suitable for applications where through-hole mounting is preferred and higher thermal capability is beneficial, provided circuit board layout can accommodate TO-220-3 footprint and driver circuits support higher gate charge.

Frequently Asked Questions (FAQ)

Q: Can AUIRG4BC30SSTRL directly replace IRG4BC30S-STRLP without circuit modification?

A: Yes. AUIRG4BC30SSTRL is a parametric equivalent with identical electrical specifications: 600V voltage rating, 34A collector current, 1.6V Vce(on), 50nC gate charge, and 22ns/540ns switching delays. Both use D2PAK surface mount packaging. The only difference is packaging format (Tape & Reel versus unspecified). No circuit modification is required.

Q: What are the key differences between STGB19NC60KDT4 and the main part?

A: STGB19NC60KDT4 is manufactured by STMicroelectronics rather than Infineon. It provides 35A collector current (1A higher), 125W power rating (25W higher), and faster switching delays (30ns/105ns versus 22ns/540ns). Gate charge is 55nC versus 50nC. D2PAK packaging is maintained. These differences allow operation in higher-current applications with improved switching performance.

Q: Why does IGP15N60TXKSA1 have lower collector current than the main part?

A: IGP15N60TXKSA1 is rated for 30A collector current, 4A below the main part's 34A specification. This part is positioned as a functional equivalent rather than a direct parametric replacement. It compensates with higher power rating (130W), extended temperature range (-40 to 175°C), and faster switching characteristics (17ns/188ns). The TO-220-3 through-hole package requires circuit board redesign.

Q: Can I use IGP15N60TXKSA1 in a design requiring 34A continuous current?

A: No. IGP15N60TXKSA1 is rated for 30A maximum collector current. Using it in a 34A application exceeds its electrical rating and creates reliability risk. AUIRG4BC30SSTRL or STGB19NC60KDT4 are appropriate for 34A or higher current requirements.

Q: What is the impact of higher gate charge in IGP15N60TXKSA1?

A: IGP15N60TXKSA1 specifies 87nC gate charge versus 50nC in the main part. Higher gate charge requires the driver circuit to supply more charge to switch the IGBT on and off. This increases driver current demand and switching losses. Driver circuits must be verified to support 87nC gate charge before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: AUIRG4BC30SSTRL, STGB19NC60KDT4, and IGP15N60TXKSA1 are all ROHS3 compliant. The main part IRG4BC30S-STRLP does not specify RoHS status. All substitute parts meet current regulatory requirements for hazardous substance restrictions.

Q: What packaging considerations apply to each substitute?

A: AUIRG4BC30SSTRL and STGB19NC60KDT4 both use D2PAK surface mount packaging, maintaining mechanical compatibility with the main part's footprint. IGP15N60TXKSA1 uses TO-220-3 through-hole packaging, requiring circuit board redesign and different mounting hardware. Surface mount parts are suitable for automated assembly; through-hole parts require manual or selective soldering.

Q: Which substitute part has the fastest switching speed?

A: IGP15N60TXKSA1 has the fastest switching delays at 17ns turn-on and 188ns turn-off. STGB19NC60KDT4 is intermediate at 30ns/105ns. AUIRG4BC30SSTRL matches the main part at 22ns/540ns. Faster switching reduces switching losses but may increase electromagnetic interference (EMI) in the circuit.
