IRG4PC50K IGBT Equivalent & Substitute Parts

Part Overview

The IRG4PC50K is a 600V, 52A IGBT manufactured by Infineon Technologies in TO-247AC packaging. This device is classified as obsolete, necessitating identification of active equivalent components for continued system design and maintenance applications. The part operates at maximum junction temperatures from -55°C to 150°C and delivers 200W maximum power dissipation. Due to its obsolete status, substitute parts with compatible electrical and mechanical characteristics are required for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IRG4PC50K are selected based on the following critical parameters that determine functional compatibility:

Primary Selection Criteria:

• Voltage rating: 600V minimum (allows 650V rated devices)
• Collector current: 52A minimum continuous rating
• Package type: TO-247-3 (mechanical and thermal compatibility)
• Mounting: Through Hole configuration
• Operating temperature range: -55°C minimum to 150°C minimum

Substitution Logic: Two active substitute parts are identified. The STGWA19NC60HD maintains identical voltage (600V) and current (52A) ratings with improved switching characteristics and active product status. The STGW30H65FB offers higher voltage rating (650V) with reduced current rating (30A), suitable for applications where current requirements do not exceed 30A and higher voltage margin is beneficial.

Engineering Selection Recommendations

STGWA19NC60HD Selection Criteria: This substitute maintains exact voltage (600V) and current (52A) specifications as the IRG4PC50K. The device is classified as active product status with ROHS3 compliance. Switching energy is significantly reduced (85µJ on, 189µJ off versus 490µJ on, 680µJ off), resulting in lower switching losses and improved thermal performance. Gate charge is reduced to 53nC from 200nC, enabling faster switching transitions. Operating temperature range matches the original part (-55°C to 150°C). This substitute is suitable for direct replacement in applications requiring identical electrical ratings with improved efficiency characteristics.

STGW30H65FB Selection Criteria: This substitute provides higher voltage rating (650V) with reduced continuous current rating (30A). Selection is appropriate for applications where maximum collector current does not exceed 30A and higher voltage margin provides system design benefits. The device features active product status with ROHS3 compliance and extended operating temperature range (-55°C to 175°C). Switching energy characteristics (151µJ on, 293µJ off) fall between the original part and STGWA19NC60HD. This substitute is suitable for applications with current requirements below 30A where voltage headroom is advantageous.

Frequently Asked Questions (FAQ)

Q: Can STGWA19NC60HD directly replace IRG4PC50K in all applications? A: STGWA19NC60HD maintains identical voltage (600V) and current (52A) ratings with compatible TO-247-3 packaging and through-hole mounting. Both devices operate across -55°C to 150°C temperature range. Direct replacement is supported from an electrical and mechanical standpoint. Reduced switching energy and gate charge may improve system performance.

Q: What are the current limitations when using STGW30H65FB as a substitute? A: STGW30H65FB is rated for maximum 30A continuous collector current, compared to 52A for the IRG4PC50K. This substitute is applicable only in applications where actual collector current does not exceed 30A. Pulsed current rating is 120A, higher than the original part's 104A.

Q: Are both substitute parts RoHS compliant? A: Both STGWA19NC60HD and STGW30H65FB are ROHS3 compliant. The original IRG4PC50K is RoHS non-compliant. Substitution with either active part satisfies RoHS compliance requirements.

Q: How do switching characteristics differ between the three parts? A: STGWA19NC60HD exhibits the fastest switching with 25ns turn-on and 97ns turn-off delays, plus lowest switching energy (85µJ on, 189µJ off). STGW30H65FB provides intermediate switching performance (37ns on, 146ns off, 151µJ on, 293µJ off). IRG4PC50K has the slowest switching (38ns on, 160ns off) with highest switching energy (490µJ on, 680µJ off). Faster switching reduces conduction losses but may increase EMI considerations.

Q: Is the TO-247-3 package identical across all three parts? A: All three parts use TO-247-3 package classification with through-hole mounting. STGWA19NC60HD is supplied in TO-247 Long Leads configuration. Physical lead length differences may require PCB layout verification, though both accommodate standard TO-247-3 footprints.

Q: What is the gate charge significance for substitution? A: Gate charge affects driver circuit requirements and switching speed. IRG4PC50K requires 200nC gate charge. STGWA19NC60HD requires only 53nC, reducing driver power dissipation and enabling faster switching. STGW30H65FB requires 149nC. Lower gate charge generally improves switching efficiency but may require driver circuit optimization.

Q: Can temperature range differences affect substitution decisions? A: IRG4PC50K and STGWA19NC60HD both operate -55°C to 150°C. STGW30H65FB extends to 175°C maximum junction temperature. For applications operating near 150°C, STGW30H65FB provides additional thermal margin. For standard applications within -55°C to 150°C range, all three parts are compatible.
