Product details
Overview
RJK0348DPA-00#J0 from Renesas Electronics is a silicon N-channel power MOSFET designed for high-efficiency DC-DC conversion and motor drive switching, featuring 30 V VDSS, 40 A continuous drain current (ID), 2.6 mΩ typical RDS(on) at VGS = 10 V, and LFPAK (PTZZ0005DA-A) surface-mount package optimized for thermal performance in compact power stages.
For engineers reviewing the RJK0348DPA-00#J0 datasheet, RJK0348DPA-00#J0 pinout, RJK0348DPA-00#J0 application, or RJK0348DPA-00#J0 equivalent, this device supports 4.5 V gate drive compatibility, delivers low conduction loss in synchronous buck converters, and enables high-density mounting in automotive body control modules and industrial PLC output stages.
Technical Context
This MOSFET employs a trench-gate process to achieve low RDS(on) and fast switching with 5.8 ns turn-on delay and 45 ns turn-off delay under standard test conditions. Its 3380 pF input capacitance (Ciss) and 190 pF reverse transfer capacitance (Crss) support stable gate drive design in hard-switched topologies.
The integrated body diode exhibits 0.82 V forward voltage (VDF) at 40 A and 30 ns reverse recovery time (trr), enabling efficient freewheeling in H-bridge motor drives. Thermal resistance θch-c is rated at 2.5 °C/W, confirming suitability for direct heatsink mounting in thermally constrained environments.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRL3803PBF | RDS(on) = 3.0 mΩ @ 10 V; TO-220 package; higher θJA (62 °C/W vs. 2.5 °C/W case-to-chip) | Limited to lower-power, non-automotive applications due to thermal limitations and larger footprint | Select when through-hole mounting or legacy board compatibility is required, not for space-constrained automotive PCBs |
| DMT3006LPS-13 | RDS(on) = 2.7 mΩ @ 10 V; PowerDI 5060 package; Ciss = 2900 pF (vs. 3380 pF) | Lower gate charge improves high-frequency efficiency but reduced avalanche energy (25 mJ vs. 40 mJ) | Prefer for >1 MHz switching in consumer adapters where avalanche robustness is secondary to EMI reduction |
Compared with IRL3803PBF and DMT3006LPS-13, RJK0348DPA-00#J0 offers superior thermal performance via LFPAK packaging, higher avalanche energy tolerance for inductive load reliability, and tighter RDS(on) distribution-making it optimal for automotive-grade 12 V power stages where board area, thermal margin, and surge resilience are co-constrained.

FAQ
What is the maximum gate-to-source voltage rating for RJK0348DPA-00#J0?
The absolute maximum gate-to-source voltage (VGSS) for RJK0348DPA-00#J0 is ±20 V. Exceeding this rating risks permanent gate oxide damage. Designers must ensure gate drive circuits include clamping or limiting to stay within this range, especially during transient events or hot-swap conditions. The RJK0348DPA-00#J0 datasheet specifies this limit under Ta = 25°C with no derating.
Does RJK0348DPA-00#J0 support logic-level gate drive?
Yes, RJK0348DPA-00#J0 is fully compatible with 4.5 V logic-level gate drive, delivering 3.5 mΩ max RDS(on) at VGS = 4.5 V. This allows direct interface with 3.3 V or 5 V microcontrollers without external level shifters. The RJK0348DPA-00#J0 gate threshold voltage range (1.2–2.5 V) ensures robust turn-on margin across process and temperature variation.
What is the thermal resistance from channel to case for RJK0348DPA-00#J0?
The channel-to-case thermal resistance (θch-c) of RJK0348DPA-00#J0 is 2.5 °C/W, measured at Tc = 25°C. This value reflects direct conduction from the silicon die to the exposed drain pad in the LFPAK package. It enables accurate junction temperature estimation when mounted on a thermally optimized PCB, and is critical for validating RJK0348DPA-00#J0 operation under sustained 40 A loads.
Can RJK0348DPA-00#J0 be used in avalanche mode?
Yes, RJK0348DPA-00#J0 is rated for repetitive avalanche operation with IAP = 20 A and EAR = 40 mJ at Tch = 25°C. These parameters are validated using the specified test circuit with Rg ≥ 50 Ω. Designers must observe the derating curve in the RJK0348DPA-00#J0 datasheet and avoid exceeding the safe operating area during unclamped inductive switching events.
Is RJK0348DPA-00#J0 compliant with automotive qualification standards?
RJK0348DPA-00#J0 is manufactured to Renesas' "Standard" quality grade per their internal classification, intended for applications including automotive body electronics (e.g., lighting, window lifts, seat controls). While not explicitly AEC-Q101 certified in the provided datasheet, its construction, testing, and thermal robustness align with automotive subsystem requirements. Customers requiring formal AEC-Q101 validation should consult Renesas for qualified variants or additional qualification reports for RJK0348DPA-00#J0.
