The PJT138K-AU_R1_000A1 is a 50V N-Channel Enhancement Mode MOSFET manufactured by Panjit International Inc. It features an SOT-363 package and supports surface mount installation. Key electrical parameters include a drain-source voltage (Vds) of 50V, continuous drain current (Id) of 360mA at Ta, and a maximum power dissipation (Pd) of 236mW at Ta. The device exhibits a typical on-resistance (Rds(on)) of 1.6 Ohms at 500mA and 10V gate-source voltage. Gate threshold voltage (Vgs(th)) is specified at 1.5V with 250µA current. Input capacitance is 50pF at 25V, and gate charge is 1nC at 4.5V. Operating temperature ranges from -55°C to +150°C TJ. It holds AEC-Q101 qualification for automotive applications.
Verify the specific suffix R1_000A1 against official Panjit documentation to confirm package type and reel specifications. Ensure compatibility with SOT-363 footprint requirements in your PCB layout. Confirm AEC-Q101 certification status if deploying in automotive environments. Cross-reference datasheet revisions to ensure parameter consistency. Validate thermal management capabilities given the 236mW power dissipation limit.
Select this component when a 50V N-channel MOSFET with integrated ESD protection is required in space-constrained designs. The SOT-363 package offers a compact solution compared to standard SOT-23 variants. Consider the 360mA current rating and 1.6 Ohm on-resistance for load matching. Verify that the -55°C to 150°C operating range meets environmental conditions. Check gate charge requirements for driving speed needs.
