IKWH70N65WR6XKSA1

Overview

The IKWH70N65WR6XKSA1 is a TRENCHSTOP™ 5 WR6 IGBT with an integrated monolithic diode, housed in a PG-TO247-3-STD-NN4.8 package. It features a collector-emitter voltage of 650 V and a continuous collector current of 122 A at 25°C. The device offers low saturation voltage (VCEsat typ. 1.55 V) and optimized switching energy (Eon typ. 2.2 mJ, Eoff typ. 1.07 mJ). Key reliability enhancements include pin-to-pin creepage distance exceeding 4.8 mm and clearance distance over 3.4 mm.

Feature Summary

• Enhanced package design providing improved reliability against contamination through increased creepage and clearance distances.
• Monolithic anti-parallel diode specifically optimized for Power Factor Correction (PFC) and welding applications.
• Positive temperature coefficient of VCEsat enabling easy parallel switching capability without thermal runaway risks.

Applications

• Power Factor Correction (PFC) circuits
• Welding power supplies
• Zero Current Switching (ZCS) applications

Procurement Notes

Verify the specific ordering suffix XKSA1 to confirm the enhanced creepage and clearance package variant. Ensure the application environment does not exceed the maximum junction temperature of 175°C. Confirm that the mounting torque remains within the specified limit of 0.6 Nm for M3 screws. Validate that the operating conditions do not surpass 80% of the maximum ratings for optimal lifetime.

Selection Notes

Select this component when high reliability in contaminated environments is required due to its enhanced insulation distances. It is suitable for designs needing stable temperature behavior and low switching losses. Consider the 122 A DC current rating at 25°C case temperature for thermal management planning. Verify compatibility with standard TO-247 footprints while accounting for the specific NN4.8 package dimensions.

Part Context

This part belongs to Infineon's TRENCHSTOP™ 5 WR6 family, which focuses on industrial-grade reliability. Unlike standard TO-247 packages, this variant utilizes a specialized mold compound and lead frame configuration to achieve superior electrical isolation between pins. It serves as a robust discrete solution for medium-power industrial converters where long-term stability under harsh conditions is critical.

Replacement Considerations

Direct substitutes must match the 650V/70A+ rating and the specific PG-TO247-3-STD-NN4.8 package with >4.8mm creepage. Standard TO-247-3 replacements lacking the enhanced clearance may not fit or meet reliability requirements in contaminated environments. Check datasheets for equivalent VCEsat and switching energy characteristics to ensure circuit performance parity.

FAQ
