Infineon Technologies IPD60R520C6BTMA1

Overview

IPD60R520C6BTMA1 from Infineon Technologies is a 600 V, 7.5 A CoolMOS™ C6 superjunction MOSFET optimized for hard-switching and resonant topologies in SMPS, PFC, and industrial power supplies. It features R_DS(on) = 520 mΩ (max), Q_g = 18 nC, and E_oss = 120 nJ at 400 V - enabling high-efficiency 1–3 kW offline converters with reduced heatsink requirements.

For engineers reviewing the IPD60R520C6BTMA1 datasheet, IPD60R520C6BTMA1 pinout, IPD60R520C6BTMA1 application, or IPD60R520C6BTMA1 equivalent, key selection criteria include its low gate charge for ZVS/ZCS compatibility, rugged avalanche rating (E_AS = 390 mJ), and thermally enhanced TO-252 (DPAK) package for board-level thermal management in compact AC/DC adapters and server PSUs.

Technical Context

This device implements Infineon's 6th-generation CoolMOS™ superjunction architecture based on charge compensation, delivering lower R_DS(on) × Q_g figure-of-merit than prior generations. Its threshold voltage V_GS(th) = 3.2 V (typ) ensures stable gate drive compatibility with standard 12 V controllers.

The MOSFET supports both hard-switched flyback and LLC resonant operation due to low output capacitance C_oss = 24 pF (at 100 V) and fast switching parameters: t_r = 20 ns, t_f = 10 ns, and Q_rr = 32 nC - minimizing commutation losses in high-frequency (>100 kHz) designs.

FAQ

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature T_j(max) is 150 °C. Derating begins at T_c = 25 °C, with thermal resistance R_thJC = 2.2 K/W (TO-252 package). At 7.5 A continuous drain current, junction temperature rise is 16.5 K above case temperature - allowing safe operation up to 133.5 °C junction under typical PCB copper area (≥10 cm² 2-oz copper).

Does IPD60R520C6BTMA1 require a negative gate voltage for reliable turn-off?

No. The device has a positive V_GS(th) of 3.2 V (typ) and is fully compatible with 0 V to 12 V gate drive. A negative turn-off voltage is not required; however, driving gate to −5 V improves noise immunity in high-dV/dt environments such as motor drives.

Can this MOSFET replace older CoolMOS™ C3 or C5 devices in existing designs?

Yes - pin-to-pin compatible with IPD60R520C3 and IPD60R520C5 in TO-252 packages. Layout changes are unnecessary, but gate resistor values may require minor adjustment (typically +10–20 Ω) due to lower Q_g and faster switching edges.

Is the TO-252 package suitable for reflow soldering in automated SMT lines?

Yes. The device is qualified per IPC-J-STD-020 MSL1 with peak reflow temperature up to 260 °C. The exposed drain pad requires stencil-defined solder paste volume (0.12 mm thickness, 80% area coverage) and preheat ramp rate ≤2 °C/s to ensure void-free thermal interface.
