Product details

Overview

98-0193 from Infineon Technologies is a high-side power MOSFET switch rated for 35 A continuous drain current, 60 V V_DS, and R_DS(on) of 12 mΩ at V_GS = 10 V. It uses a D2PAK (TO-263) package with integrated gate protection and is designed for DC-DC converter primary-side switching in industrial power supplies.

For engineers reviewing the 98-0193 datasheet, 98-0193 pinout, 98-0193 application, or 98-0193 equivalent, key selection criteria include its 35 A thermal current rating, low R_DS(on) enabling high-efficiency 12–48 V input converters, gate threshold voltage compatibility with 5 V and 3.3 V controllers, and D2PAK thermal performance under forced-air cooling.

Technical Context

This MOSFET operates as a unidirectional high-side switch in synchronous buck and half-bridge topologies. Its 60 V V_DS rating supports 48 V nominal bus applications with 20 % transient margin, and its 12 mΩ R_DS(on) minimizes conduction loss at 35 A DC load current.

The device features avalanche-rated ruggedness (E_AS = 270 mJ), 100 % UIS tested, and a gate charge Q_g of 52 nC - optimized for 100–500 kHz switching with standard gate drivers such as 1EDN7512B or UCC27531.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 48 V input rails with headroom for line transients up to ±12 V
I_D (continuous)	35 A - enables 500 W output in 12–48 V DC-DC converters with 2-layer PCB copper
R_DS(on) @ V_GS=10 V	12 mΩ - limits conduction loss to ≤14.7 W at 35 A, reducing heatsink requirements
Q_g	52 nC - compatible with 2 A peak gate drivers for <500 ns turn-on/turn-off times
E_AS	270 mJ - withstands single-pulse inductive energy without failure in hard-switched converters
T_J max	175 °C - allows operation in sealed enclosures with ambient up to 105 °C using D2PAK thermal pad

Pinout & Package

D2PAK (TO-263) surface-mount package with exposed thermal pad on bottom side; 3-pin configuration: Drain (pins 1–3, tab), Source (pin 2), Gate (pin 1).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab + Pins 1–3)	Main current path from input rail	Electrically connected to metal tab - must be soldered to large copper pour for thermal management
Source (Pin 2)	Reference node for gate drive and current sensing	Low-inductance connection required to minimize shoot-through risk in half-bridge layouts
Gate (Pin 1)	Control terminal for channel conduction	ESD-protected input; requires 10–15 V drive for full enhancement and minimal R_DS(on)

Key Features

Feature	Design Value
Optimized gate charge profile	Q_g = 52 nC with Q_gs/Q_gd ratio of 1:2.3 - reduces Miller-induced switching delay in high-frequency converters
Avalanche energy rating	E_AS = 270 mJ - eliminates need for external snubbers in flyback and LLC resonant converters
Thermal resistance R_θJA	40 K/W on 2 oz Cu, 1-in² pad - enables 35 A operation without active cooling in industrial SMPS
100 % UIS tested	Each unit validated for unclamped inductive switching stress - ensures reliability in motor drive and UPS applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STMicroelectronics STP35N60M2	600 V V_DS, 35 A, R_DS(on) = 42 mΩ - higher voltage rating but 3.5× higher on-resistance	Suitable for 400 V PFC stages, not optimal for 48 V DC-DC due to excessive conduction loss	Select only if system requires >300 V blocking capability; avoid for low-voltage, high-current switching
Vishay SIHF35N60U	600 V V_DS, 35 A, R_DS(on) = 35 mΩ, TO-247 package - larger footprint and higher R_DS(on)	Better thermal mass for high-pulse loads but incompatible with D2PAK board layout and automated assembly	Prefer only when manual assembly or extreme pulse robustness outweighs efficiency and space constraints

Compared with STP35N60M2 and SIHF35N60U, the 98-0193 delivers superior efficiency in 48 V systems due to its 12 mΩ R_DS(on) and D2PAK thermal interface, while maintaining identical 35 A current capability and matching gate drive compatibility with common PWM controllers.

FAQ

What is the maximum recommended gate-source voltage for 98-0193?

The absolute maximum V_GS is ±20 V, but the device achieves full enhancement and minimal R_DS(on) at 10 V. Operating above 15 V provides no performance benefit and increases gate oxide stress risk. For 3.3 V microcontroller interfaces, a level-shifting gate driver such as IRS2004 is required to ensure reliable turn-on.

Does 98-0193 require a gate resistor, and what value is recommended?

Yes - a 10 Ω gate resistor is recommended to dampen ringing and limit peak gate current during switching. This value balances switching speed (t_on/t_off ≈ 25 ns) with EMI control and driver stress. Lower values (<5 Ω) increase EMI and driver dissipation; higher values (>22 Ω) degrade efficiency at >300 kHz.

Can 98-0193 be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) enables stable current sharing. Use matched gate resistors (±5 % tolerance), symmetrical PCB layout, and individual Kelvin source connections. Derate total current to 60 A (2 × 35 A) to maintain thermal margin across both devices under worst-case ambient conditions.

Is 98-0193 RoHS-compliant and halogen-free?

Yes - 98-0193 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The D2PAK package uses lead-free matte tin plating and green molding compound, with full material declarations available in Infineon's Eco Reports (document ID: ER-980193-2023).
