FAQ
What is the maximum gate-to-source voltage rating for RJK0392DPA-WS#J53?
The RJK0392DPA-WS#J53 has a maximum gate-to-source voltage rating of ±20 V, as specified in its Absolute Maximum Ratings table. Exceeding this voltage risks permanent gate oxide damage. This rating applies across the full operating temperature range and must be respected during both static handling and dynamic switching events, including voltage overshoots caused by parasitic inductance in gate drive loops.
Does RJK0392DPA-WS#J53 support logic-level gate drive?
Yes, the RJK0392DPA-WS#J53 supports logic-level gate drive: its RDS(on) is guaranteed at 4.8 mΩ max with VGS = 4.5 V, and VGS(th) ranges from 1.2 V to 2.5 V. This allows direct interfacing with 3.3 V or 5 V microcontroller GPIOs or dedicated low-voltage gate drivers without level-shifting circuitry.
What is the thermal resistance from channel to case for RJK0392DPA-WS#J53?
The channel-to-case thermal resistance (θch–c) of the RJK0392DPA-WS#J53 is 2.78°C/W, measured under Tc = 25°C conditions. This value reflects the intrinsic thermal path from the silicon channel to the bottom thermal pad and is critical for calculating junction temperature rise when mounted on a properly designed copper pour or heatsink.
Is RJK0392DPA-WS#J53 rated for avalanche operation?
Yes, the RJK0392DPA-WS#J53 is explicitly rated for repetitive avalanche operation: it specifies IAP = 17 A and EAR = 28.9 mJ at Tch = 25°C with Rg ≥ 50 Ω. This ruggedness enables reliable operation in inductive switching applications such as motor drives where voltage spikes exceed VDSS.
What package type does RJK0392DPA-WS#J53 use and what are its key mechanical features?
RJK0392DPA-WS#J53 uses the WPAK(3F) package (RENESAS code PWSN0008DE-A), a leadless surface-mount package measuring 5.9 × 4.9 mm with an exposed drain pad. Key features include three source terminals (pins 1–3), one gate (pin 4), and four drain terminals (pins 5–8), plus stand-off height ≤0.05 mm for solder joint reliability and thermal interface consistency.
