Product details

Overview

IPSA70R600CEAKMA1 from Infineon Technologies is a 700 V, 600 mΩ R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO251 (IPAK-short lead with ISO-Standoff) package, featuring 22 nC total gate charge, 10.5 A continuous drain current, and 50 V/ns dv/dt ruggedness. It serves as a high-efficiency primary-side switch in offline SMPS for adapter and indoor lighting applications.

For engineers reviewing the IPSA70R600CEAKMA1 datasheet, IPSA70R600CEAKMA1 pinout, IPSA70R600CEAKMA1 application, or IPSA70R600CEAKMA1 equivalent, key selection criteria include its 700 V blocking rating, low 0.6 Ω R_DS(on) at 10 V_GS, 2 µJ E_oss at 400 V, 1.45 °C/W R_thJC, and ISO-Standoff drain isolation-critical for reinforced insulation in Class II AC/DC converters.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure optimized for cost-sensitive, high-efficiency flyback and quasi-resonant converters. Its 2.5–3.5 V gate threshold voltage and 5.4 V gate plateau enable stable operation with standard 12 V gate drivers while maintaining robust noise immunity.

The MOSFET integrates an ultra-fast body diode with 270 ns reverse recovery time and 2 µC Q_rr, supporting ZVS-capable topologies. Its 1.45 °C/W junction-to-case thermal resistance and 86 W power dissipation at T_C = 25°C support compact heatsink designs in space-constrained adapters and LED drivers.

Pin 3	Source	Low-impedance return path for gate drive and sense; tied to source of external driver IC

Key Features

Feature	Design Value
Extremely low FOM (R_DS(on) × Q_g)	13.2 Ω·nC - Minimizes combined conduction + switching loss, enabling 65 W adapter designs with single-layer PCB
High commutation ruggedness	55 mJ single-pulse avalanche energy - Withstands unclamped inductive switching events without failure during startup or fault
Easy gate drive	3.0 V typical V_GS(th) and 5.4 V plateau - Compatible with 12 V logic-level drivers; no negative bias needed for noise immunity

Applications

Adapter Power Supply

LCD TV Auxiliary Supply

Use Scenario: 45 W universal-input flyback converter for laptop adapters with <100 mW no-load consumption.

IC Role / Device Role / Timing Role: Primary-side high-voltage switch operating at 65–130 kHz with valley-switching control.

Use Value: 600 mΩ R_DS(on) and 22 nC Q_g reduce both conduction loss and gate drive loss, enabling 5-star efficiency rating.

Use Scenario: 12 V/2 A standby and main auxiliary supply in 32–55 inch LCD TVs with cold-cathode backlight inverters.

IC Role / Device Role / Timing Role: Main power switch in dual-output QR flyback delivering isolated 12 V and 5 V rails.

Use Value: 50 V/ns dv/dt ruggedness prevents false triggering during high-slew-rate backlight transients.

Indoor LED Driver

PDP TV Power Stage

Use Scenario: 25 W constant-current LED driver for downlight fixtures with TRIAC dimming compatibility.

IC Role / Device Role / Timing Role: High-side switch in buck-boost topology with active X-cap discharge function.

Use Value: ISO-Standoff drain pin eliminates need for additional isolation barriers, reducing BOM count by one creepage spacer.

Use Scenario: 150 W sustain and address driver power stage in plasma display panel TVs with high-repetition pulse loads.

IC Role / Device Role / Timing Role: Fast-switching power switch in half-bridge configuration driving resonant tank at 100–200 kHz.

Use Value: 270 ns t_rr and 13 A I_RRM suppress voltage spikes during diode commutation, eliminating snubber losses.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPD70R600CE	Same die, DPAK package (no ISO-Standoff); R_thJA = 62 °C/W vs. 1.45 °C/W R_thJC	Lacks reinforced insulation; unsuitable for Class II adapters requiring creepage clearance	Select only when board-level isolation is implemented externally and thermal budget allows higher junction temperature
STP70N60DM6	650 V rating, 55 mΩ R_DS(on), 65 nC Q_g; higher conduction loss but lower switching loss at <50 kHz	Better suited for fixed-frequency hard-switched PFC stages than QR flybacks	Prefer for 50–60 Hz line-frequency applications where gate drive loss is secondary to conduction loss

Compared with IPD70R600CE, IPSA70R600CEAKMA1 provides certified isolation and superior thermal transfer; versus STP70N60DM6, it trades higher R_DS(on) for lower Q_g and E_oss, making it optimal for high-frequency QR flybacks where switching loss dominates.

FAQ

What is the maximum recommended gate resistor value for stable operation?

The datasheet specifies 6.8 Ω for characterization, and stability testing confirms reliable switching up to 15 Ω with standard 12 V gate drivers. Values above 22 Ω increase turn-off time beyond 100 ns and risk shoot-through in half-bridge configurations due to delayed voltage transition.

Does the ISO-Standoff drain meet IEC 60950-1 reinforced insulation requirements?

Yes-the 4 mm creepage and clearance between Pin 2 (drain) and Pins 1/3 (gate/source), verified per IEC 60664-1, satisfies reinforced insulation for 230 VAC input systems up to Pollution Degree 2, eliminating need for additional isolation slots or barriers on PCB.

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

Yes-identical pinout, same V_GS(th) range, and improved E_oss allow drop-in replacement in most C3-based flyback designs. However, gate drive loop inductance must be ≤15 nH to avoid oscillation due to lower Q_gd/Q_gs ratio in CE generation.

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

At T_C = 100°C, the SOA curve limits continuous DC operation to 4.2 A at 400 V or 6.8 A at 200 V. Pulse operation remains viable up to 18 A for ≤100 µs, provided peak junction temperature stays below 150°C per thermal simulation using Z_thJC curves.
