Product details

Overview

IRLMS6802TR from Infineon Technologies is a P-channel enhancement-mode HEXFET® Power MOSFET in Micro6™ (SOT-23-6) package, rated for -20 V V_DS, 0.050 Ω R_DS(on) at V_GS = -4.5 V and I_D = -5.1 A, with -45 A pulsed drain current capability. It serves as a low-side load switch in portable battery-powered systems requiring compact, high-efficiency power control.

For engineers reviewing the IRLMS6802TR datasheet, IRLMS6802TR pinout, IRLMS6802TR application, or IRLMS6802TR equivalent, key selection criteria include verified R_DS(on) at -4.5 V, thermal resistance of 62.5 °C/W, avalanche energy rating of 31 mJ, and Micro6™ package compatibility with space-constrained PCB layouts.

Technical Context

This device operates as a voltage-controlled unidirectional switch with integrated body diode, optimized for synchronous rectification and reverse-polarity protection. Its gate threshold voltage range (-0.6 to -1.2 V) enables direct logic-level drive from 3.3 V microcontrollers without level-shifting.

The Micro6™ package features a custom leadframe that reduces R_DS(on) by 60% versus standard SOT-23 while increasing current-handling capacity by nearly 300%. Thermal performance is validated via junction-to-ambient resistance of 62.5 °C/W on FR-4 board.

E_AS	31 mJ - Withstands single-pulse inductive switching transients up to 3.0 A in 6.8 mH loads
Q_g	11–16 nC - Low gate charge allows fast turn-on with minimal driver current demand
R_θJA	62.5 °C/W - Limits junction temperature rise to ≤75°C under 2 W dissipation on standard FR-4
V_GS(th)	-0.6 to -1.2 V - Ensures reliable turn-on from 3.3 V GPIO without external biasing

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SI2305DS-T1-E3	R_DS(on) = 0.055 Ω @ -4.5 V; higher Q_g (18 nC); R_θJA = 110 °C/W	Lower thermal performance limits continuous current to ~3.5 A on FR-4	Prefer when cost sensitivity outweighs thermal margin requirements
DMN2011UFG-7	R_DS(on) = 0.045 Ω @ -4.5 V; lower V_GS(th) (-0.5 to -1.0 V); same Micro6™ footprint	Improved gate threshold consistency enables tighter timing control in fast-switching designs	Choose for higher efficiency and tighter V_GS(th) tolerance in precision power gating

Compared with SI2305DS-T1-E3 and DMN2011UFG-7, the IRLMS6802TR offers balanced R_DS(on), gate charge, and thermal resistance-making it optimal for mid-range current battery switches where reliability and layout simplicity are prioritized over marginal efficiency gains.

FAQ

What is the maximum continuous drain current at 70°C ambient?

The IRLMS6802TR supports -4.5 A continuous drain current at T_A = 70°C with V_GS = -4.5 V. This derating reflects thermal limitations of the Micro6™ package on standard FR-4 PCBs, where power dissipation drops from 2.0 W at 25°C to 1.3 W at 70°C due to linear derating factor of 0.016 W/°C.

Does this MOSFET require a gate resistor for stability?

A gate resistor (typically 10–100 Ω) is recommended to dampen ringing caused by gate-drain capacitance (C_rss = 152 pF) and PCB trace inductance during fast switching. While not mandatory for DC operation, it improves EMI performance and prevents unintended oscillation when driven by high-speed microcontroller GPIOs.

Can the body diode conduct continuously in reverse direction?

Yes-the integrated body diode supports continuous reverse current up to -1.6 A at 25°C (V_SD = -1.2 V), with pulse capability up to -45 A. However, sustained conduction generates heat in the diode junction; thermal design must account for both MOSFET channel and diode losses when used in freewheeling or OR-ing topologies.

Is the Micro6™ package compatible with standard SOT-23-6 reflow profiles?

Yes-the IRLMS6802TR's Micro6™ package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C). Its thermal pad layout matches industry-standard SOT-23-6 footprints, though optimal thermal performance requires soldering all four drain pads to a dedicated copper pour.
