Product details

Overview

ISC320N12LM6ATMA1 from Infineon Technologies is an N-channel logic-level SuperSO8-packaged MOSFET rated for 120 V drain-source voltage, 32 mΩ max R_DS(on) at V_GS = 10 V, 24 A continuous drain current, and optimized for high-frequency synchronous rectification in DC-DC converters and motor drives.

For engineers reviewing the ISC320N12LM6ATMA1 datasheet, ISC320N12LM6ATMA1 pinout, ISC320N12LM6ATMA1 application, or ISC320N12LM6ATMA1 equivalent, key selection criteria include its 20.3 nC Q_rr at 1000 A/µs, 4.1 nC gate charge (0–4.5 V), 175 °C operating temperature, and internal body diode with 0.86 V forward voltage at 9 A.

Technical Context

This OptiMOSTM 6 device uses trench-gate silicon technology with optimized cell layout to achieve low gate charge × R_DS(on) figure-of-merit (FOM) and reduced reverse recovery charge. Its 120 V V_DS rating supports industrial 48 V and 60 V bus systems while maintaining robust avalanche energy (33 mJ).

The MOSFET features dual thermal paths-3.5 °C/W junction-to-case (bottom) and 20 °C/W (top)-enabling flexible PCB cooling strategies. Gate threshold voltage (1.2–2.2 V) ensures reliable turn-on with 3.3 V and 4.5 V logic drivers, and its 100.0 mΩ R_DS(on) at V_GS = 3.3 V enables partial-load efficiency optimization.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	120 V - Supports 48 V/60 V industrial bus rails with 2× safety margin against transients
R_DS(on), max	32 mΩ @ V_GS = 10 V - Enables <1.5 W conduction loss at 24 A, critical for thermally constrained designs
Q_rr	20.3 nC @ dI/dt = 1000 A/µs - Reduces switching losses and EMI in hard-switched synchronous rectifiers
Q_G (0–4.5 V)	4.1 nC - Allows fast, low-power gate driving with standard 3.3 V microcontrollers or gate drivers
T_j max	175 °C - Permits operation in sealed enclosures or high-ambient environments without derating
I_D, cont	24 A @ T_C = 25 °C - Sustains full load in compact heatsinkless power stages using 6 cm² copper area
C_iss	650 pF max - Limits Miller-induced shoot-through risk in half-bridge configurations

Pinout & Package

ISC320N12LM6ATMA1 is housed in PG-TDSON-8 (SuperSO8), a 5 mm × 6 mm surface-mount package with exposed drain pad on bottom for thermal dissipation. Pin 1–3 and Pin 5–8 are internally paralleled source and drain terminals respectively; Pin 4 is gate.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1–3	Source	Low-inductance parallel connection for return path integrity and Kelvin sensing compatibility
Pin 4	Gate	Single-point control input; requires <1.5 Ω external gate resistor to damp ringing per layout guidelines
Pin 5–8	Drain	Internally paralleled high-current output node tied to exposed thermal pad for PCB heat spreading

Key Features

Feature	Design Value
N-channel logic-level operation	Turns fully on with 3.3 V or 4.5 V gate drive-eliminates need for level-shifting in MCU-based power stages
Low Q_rr / Q_G ratio	20.3 nC Q_rr ÷ 4.1 nC Q_G ≈ 4.9 - Improves light-load efficiency in buck converters vs. legacy MOSFETs
High avalanche energy rating	33 mJ single-pulse E_AS - Withstands inductive kickback in motor gate drivers without snubbers
175 °C junction rating	Enables operation in automotive under-hood or industrial PLC modules without active cooling
Pb-free & halogen-free	RoHS-compliant plating and IEC61249-2-21 compliance - Meets EU and China RoHS requirements for export

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 120 V logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N12F7	R_DS(on) = 28 mΩ @ 10 V, Q_rr = 26.5 nC, PG-TDSON-8, same 120 V rating	Higher Q_rr increases switching loss in >500 kHz designs; lower R_DS(on) benefits conduction-limited cases	Prefer when conduction loss dominates and layout permits higher EMI filtering
IXTP320N12X4	TO-220 package, R_DS(on) = 32 mΩ @ 10 V, Q_rr = 34 nC, 120 V, no logic-level gate	Requires 10 V gate drive; unsuitable for 3.3 V control; superior thermal mass but larger footprint	Select only for retrofit into legacy through-hole designs where board space is unconstrained

Compared with STL220N12F7 and IXTP320N12X4, ISC320N12LM6ATMA1 delivers optimal balance of low Q_rr, logic-level compatibility, and SuperSO8 thermal performance-making it preferred for new high-frequency, space-constrained industrial and telecom power designs.

FAQ

What is the maximum safe operating temperature for ISC320N12LM6ATMA1?

The absolute maximum junction temperature is 175 °C, verified per JEDEC JESD22-A108 qualification. Continuous operation at this temperature requires thermal design ensuring case temperature remains ≤125 °C under worst-case ambient and power dissipation conditions, as defined in the datasheet's de-rating curves.

Does ISC320N12LM6ATMA1 have an integrated body diode, and what are its key parameters?

Yes-it features an internal anti-parallel body diode with 24 A continuous forward current rating at T_C = 25 °C, 0.86 V typical forward voltage at 9 A and 25 °C, and 20.3 nC reverse recovery charge at 1000 A/µs di/dt. These values are measured and specified in Table 7 of the datasheet.

Can ISC320N12LM6ATMA1 be driven directly by a 3.3 V microcontroller GPIO?

Yes-its gate threshold voltage range (1.2–2.2 V) and guaranteed R_DS(on) of 100 mΩ at V_GS = 3.3 V enable direct drive. However, a series gate resistor (≥10 Ω) is recommended to limit peak current and suppress ringing, especially in layouts with >10 nH gate loop inductance.

What is the meaning of "SuperSO8" package designation for this MOSFET?

SuperSO8 is Infineon's trademarked name for PG-TDSON-8: a 5 mm × 6 mm, 1.27 mm height surface-mount package with eight leads and an exposed drain pad on the bottom. It provides enhanced thermal performance over standard SO8 via direct PCB copper contact and low-inductance source/drain terminal paralleling.
