Overview

Description

IRLR3103TR is a logic-level N-channel enhancement-mode power MOSFET from International Rectifier (now Infineon). It’s intended for switching and power‑control tasks in compact, low‑voltage/high‑current circuits such as DC–DC converters, motor drivers, and load switches.
Key points:
- Logic-level gate drive: can be driven from standard 4.5–10 V logic signals.
- Low on-resistance for efficient conduction.
- Suitable for surface-mount use; “TR” typically indicates Tape & Reel packaging.
What to check in the datasheet:
- Vds (drain‑to‑source voltage) and Id (continuous drain current) ratings.
- Rds(on) at your gate drive voltage (e.g., 4.5 V and 10 V).
- Vgs,max, thermal resistance, and avalanche energy rating.
Design notes:
- Provide adequate heat sinking or copper area.
- Use proper gate protection, gate resistor, and flyback protection for inductive loads.
- Ensure operation within the safe operating area and device limits.
For exact specs and packaging, consult the latest Infineon/IR datasheet.

Equivalent

Exact equivalents depend on package and specs. The IRLR3103TR is a 30 V, logic‑level N‑channel MOSFET. Please provide: package (SO‑8 or D‑PAK), required Id (A), target Rds(on), and gate drive (4 V or 10 V). With those, I’ll give cross‑references (Infineon/ST/ON Semiconductor) that match the specs.

Features

IRLR3103TR is an N-channel logic-level HEXFET power MOSFET. Key features:
- 30 V maximum drain–source voltage (VDS)
- Logic-level gate drive (ON with modest VGS; suitable for 4.5–10 V drive)
- Very low on-resistance (low conduction losses)
- High current capability for switching/regulation apps
- Fast switching characteristics with low gate charge
- Robust avalanche energy tolerance for rugged operation
- Suitable for switching power supplies, motor drivers, and DC-DC converters
- Tape & Reel (TR) packaging for automated assembly
- Pb-free, RoHS compliant
Note: exact RDS(on), ID rating, and switching specs are in the datasheet.

Pinout

- Pin count: 3 pins (Gate, Drain, Source). The package also has a drain tab connected to Drain.
- Function: N-channel enhancement-mode power MOSFET used for switching DC loads (logic-level gate drive).

Manufacturer

Manufacturer: International Rectifier (IR), a semiconductor company that specializes in power management devices (e.g., power MOSFETs, IGBTs, drivers). IR is now part of Infineon Technologies, a German multinational semiconductor company.

Application
