Product details

Overview

IPLK70R1K2P7ATMA1 from Infineon Technologies is a 700 V, 1.2 Ω R_DS(on) CoolMOS™ P7 superjunction MOSFET in PG-TDSON-8 package, rated for 5.5 A continuous drain current at T_C = 100°C, with 1000 h HTRB and HTGB qualification at 150°C - deployed in industrial AC-DC SMPS primary-side switching.

For engineers reviewing the IPLK70R1K2P7ATMA1 datasheet, IPLK70R1K2P7ATMA1 pinout, IPLK70R1K2P7ATMA1 application, or IPLK70R1K2P7ATMA1 equivalent, key selection criteria include high-voltage ruggedness (700 V), low conduction loss (1.2 Ω @ V_GS = 10 V), MSL-1 reflow compatibility, and JEDEC-qualified reliability for 1000 h high-temperature bias stress.

Technical Context

This device implements a charge-compensated superjunction structure optimized for hard-switched and quasi-resonant flyback and PFC topologies. Its gate threshold voltage (V_GS(th)) is 3.5 V (min), and total gate charge (Q_G) is 14 nC (typ) at V_GS = 10 V, enabling fast turn-on while maintaining EMI control.

The MOSFET features an integrated body diode with reverse recovery charge (Q_rr) of 120 nC (typ) and soft recovery behavior, reducing snubber losses in discontinuous conduction mode (DCM) operation. It is qualified per JEDEC JESD22-A108 (HTRB/HTGB) and JESD22-A104 (TC -55°C to +150°C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	700 V - supports universal-input offline SMPS up to 380 V_AC rectified peak without derating.
R_DS(on) max	1.2 Ω @ V_GS = 10 V, T_J = 100°C - enables <5 W conduction loss at 5.5 A in compact heatsink designs.
I_D cont	5.5 A @ T_C = 100°C - defines maximum steady-state current under standard thermal mounting conditions.
Q_G	14 nC (typ) @ V_GS = 10 V - determines gate drive power and switching speed in 65–100 kHz flyback converters.
E_oss	29 nJ (typ) @ V_DS = 400 V - quantifies output capacitance energy loss during turn-off, critical for ZVS design margin.
Q_rr	120 nC (typ) @ I_F = 5.5 A, dI/dt = 100 A/µs - sets diode recovery loss and EMI in DCM PFC stages.

Pinout & Package

Package: PG-TDSON-8 (exposed drain pad, 5 mm × 6 mm footprint, 1.0 mm height), MSL Level 1 (260°C reflow compatible).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 7, 8	Drain (D)	High-side switching node connected to bulk capacitor and transformer primary; electrically tied to exposed thermal pad.
5	Source (S)	Reference node for gate drive and current sensing; connects to ground plane via low-inductance trace.
6	Gate (G)	Control input requiring 10 V drive; Miller plateau at ~4.5 V enables robust noise immunity in noisy SMPS environments.

Key Features

Feature	Design Value
Superjunction architecture	Enables 700 V rating with 1.2 Ω R_DS(on), reducing conduction loss by 35% vs. planar MOSFETs at same voltage class.
Soft body diode recovery	Q_rr = 120 nC with low dI/dt sensitivity - minimizes voltage overshoot and snubber dissipation in DCM flyback.
JEDEC-qualified reliability	1000 h HTRB/HTGB at 150°C - validates stable operation in industrial ambient temperatures up to 85°C system level.
MSL-1 packaging	Zero bake requirement before SMT reflow - eliminates moisture-related popcorning risk in high-volume manufacturing.

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
IPW65R099C7	650 V rating, 0.99 Ω R_DS(on), higher Q_G (21 nC)	Better conduction loss below 300 V_AC input; less margin above 350 V_AC	Prefer for 230 V-only systems where efficiency >1% gain justifies reduced voltage headroom.
IPP65R1K4C7	650 V, 1.4 Ω R_DS(on), lower Q_rr (85 nC), same PG-TDSON-8	Lower recovery loss in high-dI/dt PFC; higher conduction loss at full load	Choose when EMI reduction outweighs thermal penalty in space-constrained telecom rectifiers.

Compared with IPW65R099C7 and IPP65R1K4C7, IPLK70R1K2P7ATMA1 delivers optimal balance of 700 V ruggedness, 1.2 Ω conduction loss, and soft-recovery diode behavior - making it preferred for universal-input industrial SMPS where both surge immunity and efficiency matter.

FAQ

What is the maximum junction temperature rating for IPLK70R1K2P7ATMA1?

The device is rated for T_J(max) = 150°C, validated through 1000-hour high-temperature reverse bias (HTRB) and gate bias (HTGB) testing at 150°C ambient per JEDEC JESD22-A108. This allows full-rated operation in industrial enclosures up to 85°C ambient with appropriate PCB copper area and airflow.

Does IPLK70R1K2P7ATMA1 require a negative gate turn-off voltage?

No. The gate threshold voltage is 3.5 V (min), and the device is fully enhanced with 0 V gate-source voltage. A negative turn-off voltage is not required or recommended; standard 0 V to 10 V gate drive suffices for reliable switching and avoids unnecessary gate driver complexity.

Can IPLK70R1K2P7ATMA1 be used in synchronous rectification configurations?

No - this is a unidirectional N-channel high-side switch only. Its body diode is not optimized for bidirectional conduction, and it lacks the low forward voltage and fast reverse recovery needed for SR FETs. Use dedicated synchronous rectifier MOSFETs like IRFR3710Z or SiR626DP instead.

Is the PG-TDSON-8 package lead-free and RoHS compliant?

Yes. The IPLK70R1K2P7ATMA1 uses lead-free solderable terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The "ATMA1" suffix confirms tape-and-reel packaging with RoHS-compliant finish and MSL-1 handling.
