Frequently Asked Questions
Q1: Can T5, T6 and EDT3 models be used interchangeably?
A1: No. They have different voltage, current ranges and performance focuses — T5 is for basic industrial scenarios, T6 for high-frequency low-power applications, and EDT3 is automotive-grade. Only replace with the same model.
Q2: Do these IGBTs meet the certification standards of the EU and North American markets?
A2: Yes. All models comply with EU CE certification and North American UL 1557 standards. Just ask your supplier for the certification documents before purchase.
Q3: Why do T5 models sometimes overheat in welding machines?
A3: Mostly because the heatsink is dusty or mismatched. First clean the heatsink; if it still overheats, replace it with one that matches T5's thermal resistance.
Q4: Are T6 models suitable for high-frequency PV inverters?
A4: Yes. T6 models have low electromagnetic interference and a switching frequency of up to 8-30kHz, which is especially suitable for small PV string inverters below 10kW.
Q5: Can EDT3 models be used in non-automotive scenarios?
A5: Technically yes, but not recommended. EDT3 is automotive-grade and more expensive; choose T5 or T6 for industrial and new energy scenarios to save costs.
Q6: What are the common faults of these IGBTs, and how to fix them quickly?
A6: The most common is short-circuit damage (mostly caused by voltage overload). After replacing the IGBT, check if the circuit voltage matches its rated voltage.
Q7: How long is the delivery time for overseas orders?
A7: In-stock models are delivered in 2-4 weeks; out-of-stock models take 6-8 weeks. For urgent needs, contact your local Infineon distributor for consultation.
Q8: Do they need a dedicated driver?
A8: No, they are compatible with most standard IGBT drivers. Just ensure the gate drive voltage matches to avoid damaging the module.
Q9: What is the warranty period for overseas purchases?
A9: 1-year global warranty. For non-human-induced faults, contact the supplier with your order number for free replacement or repair (freight at your own expense).
Q10: Can T5/T6/EDT3 be used in high-temperature outdoor environments?
A10: Yes. T5 and T6 support a junction temperature of 175°C, and EDT3 can reach up to 185°C — all are suitable for harsh outdoor industrial and new energy scenarios.
