Product details

Overview

IPU60R950C6AKMA1 from Infineon Technologies is a 600 V, 4.4 A (T_C = 25°C) superjunction N-channel MOSFET in PG-TO251 (IPAK) package, featuring R_DS(on) = 0.95 Ω (max), Q_g = 13 nC (typ), and E_oss = 1.3 µJ @ 400 V. It delivers high commutation ruggedness (di/dt = 500 A/µs), low switching losses, and industrial-grade reliability for hard-switching PFC and resonant SMPS stages.

For engineers reviewing the IPU60R950C6AKMA1 datasheet, IPU60R950C6AKMA1 pinout, IPU60R950C6AKMA1 application, or IPU60R950C6AKMA1 equivalent, key selection criteria include its 600 V V_DSS, 0.95 Ω R_DS(on), 13 nC gate charge, 500 A/µs body diode di/dt rating, and IPAK thermal resistance of 3.41 °C/W (junction-to-case).

Technical Context

This CoolMOS™ C6 device implements a superjunction structure optimized for high-voltage, medium-power switching applications. Its 600 V breakdown voltage (V_DS = 600 V), 0.95 Ω R_DS(on), and 13 nC total gate charge enable efficient operation in continuous conduction mode (CCM) PFC and LLC resonant converters.

The MOSFET integrates a fast, robust body diode with t_rr = 220 ns and Q_rr = 1.5 µC, supporting high di/dt (500 A/µs) commutation without failure. Its dv/dt ruggedness is rated at 50 V/ns (low-side) and 15 V/ns (reverse diode), ensuring stable operation in noisy high-frequency topologies.

Pinout & Package

IPU60R950C6AKMA1 uses the PG-TO251 (IPAK) surface-mount package with exposed drain pad for enhanced thermal performance. The package features three terminals: Drain (pin 2), Gate (pin 1), and Source (pin 3), with pin 2 electrically connected to the heatsink-compatible metal tab.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; requires 10 V drive for full enhancement; gate resistance R_G = 16 Ω (1 MHz).
Pin 2	Drain	Main high-voltage current path; electrically tied to exposed metal tab for direct PCB thermal coupling.
Pin 3	Source	Reference node for gate drive and current sensing; forms common return path with gate driver ground.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPU60R1K0C6AKMA1	R_DS(on) = 1.0 Ω (max), Q_g = 11.5 nC - Higher on-resistance but lower gate charge.	Better suited for higher-frequency (>200 kHz), lower-current (<3 A) PFC where switching loss dominates.	Select when prioritizing reduced driver loss over conduction loss in compact adapter designs.
IPU60R750C6AKMA1	R_DS(on) = 0.75 Ω (max), Q_g = 15.5 nC - Lower on-resistance but higher gate charge and cost.	Preferred for high-current, lower-frequency (<100 kHz) server PSUs requiring <0.8 Ω R_DS(on).	Choose when thermal budget is tight and average current exceeds 5 A in continuous conduction mode.

Compared with IPU60R950C6AKMA1, the 1.0 Ω variant trades conduction loss for easier drive and lower EMI, while the 0.75 Ω variant improves thermal headroom at the expense of gate drive complexity and cost-making the 0.95 Ω version the balanced choice for 4–5 A industrial PFC stages.

FAQ

What is the maximum junction temperature for continuous operation?

The IPU60R950C6AKMA1 is rated for continuous operation up to T_j = 150°C, validated per JEDEC JESD22-A108. At this temperature, R_DS(on) rises to 2.22 Ω, and pulsed drain current remains limited to 12 A. Derating curves in the datasheet define safe operating area boundaries for T_C > 25°C.

Is the body diode suitable for synchronous rectification?

No-the body diode is not optimized for synchronous rectification. Its reverse recovery time (t_rr = 220 ns) and Q_rr = 1.5 µC are designed for commutation in PFC and resonant topologies, not low-loss freewheeling. Dedicated SR controllers with external MOSFETs are recommended for secondary-side rectification.

Does this part require a negative gate voltage for reliable turn-off?

No. The gate threshold voltage range (2.5–3.5 V) and positive-only gate drive compatibility allow reliable turn-off with 0 V gate potential. Negative bias is unnecessary and not specified in the datasheet; standard 0 V to 10 V gate drive suffices for all operating conditions.

How does the IPAK package compare thermally to TO-220 or DPAK?

The PG-TO251 (IPAK) package offers R_thJC = 3.41 °C/W-comparable to DPAK (≈3.0–3.5 °C/W) and significantly better than standard TO-220 (≈1.5–2.0 °C/W for isolated versions). Its exposed drain pad enables direct thermal coupling to copper pours, making it ideal for space-constrained SMD layouts without through-hole mounting.
