Product details

Overview

IKP40N65H5XKSA1 from Infineon is a 650V, 40A high-speed TRENCHSTOP™ 5 IGBT copacked with a RAPID 1 fast and soft antiparallel diode in PG-TO220-3 package. It delivers 1.65V V_CE(sat) at 40A/25°C, 95nC gate charge, and 175°C max junction temperature, enabling high-efficiency hard-switching and resonant topologies in solar converters and UPS systems.

For engineers reviewing the IKP40N65H5XKSA1 datasheet, IKP40N65H5XKSA1 pinout, IKP40N65H5XKSA1 application, or IKP40N65H5XKSA1 equivalent, key selection criteria include its low switching energy (0.14 mJ total at 5A), fast diode recovery (30 ns trr at 5A), and validated thermal resistance (0.60 K/W j-c) for industrial power control designs requiring stable 650V IGBT performance.

Technical Context

This IGBT employs TRENCHSTOP™ 5 trench-gate field-stop structure with optimized carrier lifetime control to achieve best-in-class conduction–switching trade-off. Its integrated RAPID 1 diode features soft reverse recovery (700 A/µs |dirr/dt| at 5A) and low Q_rr (0.22 µC), minimizing voltage overshoot and EMI in bridge-leg configurations.

The device operates with ±20V gate-emitter rating and supports gate drive voltages ≥7.5V for reliable saturation. Its 0.60 K/W junction-to-case thermal resistance enables 250W dissipation at 25°C case temperature, while JEDEC qualification ensures robustness in industrial environments up to 175°C junction operation.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed 650V IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IKW40N65H5	Same die, PG-TO247-3 package with lower R_th(j-c) (0.50 K/W) and higher L_E (13 nH).	Better thermal performance but larger footprint; preferred for >100W continuous conduction.	Select when heatsink interface area allows TO247 mounting and thermal budget demands <0.55 K/W j-c resistance.
FGH40N60UFD	Fairchild (ON Semi) 600V IGBT with 1.8V V_CE(sat), 110nC Q_G, no integrated diode.	Requires external ultrafast diode; higher conduction loss but wider gate voltage tolerance (±30V).	Choose when gate drive robustness against transients is prioritized over integration and efficiency.

Compared with IKW40N65H5, IKP40N65H5XKSA1 offers identical electrical specs in a smaller TO220 footprint ideal for space-constrained designs, while FGH40N60UFD trades integration and efficiency for higher gate ruggedness and legacy compatibility in retrofit upgrades.

FAQ

What is the maximum recommended gate resistor value for reliable turn-off?

A 15Ω gate resistor is validated in the datasheet for 400V/40A operation with 15V gate drive. Increasing beyond 22Ω risks extending td(off) beyond 200ns and elevating E_off by >15%, especially at 150°C junction temperature. For 100 kHz designs, keep R_G(off) ≤ 18Ω to maintain safe SOA margins.

Does the integrated RAPID 1 diode require separate gate control?

No - the RAPID 1 diode is uncontrolled and functions solely as an antiparallel freewheeling path. Its behavior is fully determined by the IGBT's switching state and load current polarity. No external gate signal or bias is needed, and it shares the same thermal mass as the IGBT die.

Can IKP40N65H5XKSA1 replace IKP40N65H3 in existing designs?

Yes - it is a documented plug-and-play replacement per Infineon's migration guide. Identical pinout, voltage/current ratings, and thermal footprint allow direct substitution. Key improvements include 25% lower E_off and 30% faster diode trr, which reduce heatsink size and improve light-load efficiency without layout changes.

What is the safe operating area (SOA) limitation at 100°C case temperature?

At T_C = 100°C, the DC collector current is limited to 46A per datasheet maximum ratings. The forward-bias SOA (Fig. 1) shows pulse capability up to 120A for t_p ≤ 100µs, but sustained operation above 46A requires active cooling or derating to maintain T_vj ≤ 175°C.
