Product details
Overview
RJK4512DPP-00#T2 from Renesas Electronics is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and motor drives, featuring 450 V VDSS, 14 A continuous drain current (ID), 0.43 Ω typical RDS(on) at VGS = 10 V, and 25 ns rise time - enabling efficient 400 V industrial power supplies.
For engineers reviewing the RJK4512DPP-00#T2 datasheet, RJK4512DPP-00#T2 pinout, RJK4512DPP-00#T2 application, or RJK4512DPP-00#T2 equivalent, key selection criteria include avalanche energy rating (0.5 mJ), body-diode reverse recovery time (280 ns), gate charge (29 nC), and TO-220FN package thermal resistance (θch-c = 4.17 °C/W).
Technical Context
This MOSFET employs a planar vertical DMOS structure optimized for fast switching with low conduction loss. Its gate threshold voltage range (3.0–4.5 V) ensures reliable turn-on under standard 10 V gate drive while maintaining noise immunity.
The integrated body diode supports freewheeling in inductive loads, with specified VDF = 0.89 V (typ.) at 14 A and trr = 280 ns under di/dt = 100 A/µs - critical for synchronous rectification and flyback snubberless designs.

|---|---|
| VDSS | 450 V - supports 400 V DC bus applications with 12.5% margin against transient overvoltage |
| ID (continuous) | 14 A at Tc = 25°C - enables 200 W+ power stages with forced-air cooling |
| RDS(on) | 0.43 Ω (typ.) at VGS = 10 V - yields ≤ 85 W conduction loss at full load in 14 A switch mode |
| Qg | 29 nC - determines gate driver power requirement and switching loss trade-off at 100 kHz+ |
| tr/tf | 25 ns / 17 ns - allows <500 ns total switching transition, minimizing overlap loss in hard-switched topologies |
| θch-c | 4.17 °C/W - enables 30 W channel dissipation with ≤125°C case temperature rise above ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP14NK45ZFP | 450 V, 14 A, RDS(on) = 0.42 Ω (typ.), but higher Qg = 45 nC and slower tr = 45 ns | Higher gate drive loss and reduced max frequency capability in high-efficiency SMPS | Prefer RJK4512DPP-00#T2 where gate drive power budget is constrained or >150 kHz operation required |
| IXTH12N45P | 450 V, 12 A, RDS(on) = 0.55 Ω (typ.), lower Ciss = 850 pF, but no specified trr or avalanche rating | Lacks body-diode recovery spec and avalanche ruggedness - unsuitable for inductive freewheeling or unclamped switching | Select RJK4512DPP-00#T2 for designs requiring guaranteed diode recovery performance or repetitive avalanche stress handling |
Compared with STP14NK45ZFP and IXTH12N45P, the RJK4512DPP-00#T2 delivers superior switching speed (25 ns rise), lower gate charge (29 nC), and documented avalanche energy (0.5 mJ), making it optimal for high-frequency, high-reliability 400 V industrial power conversion where diode recovery and thermal margin are critical.

FAQ
What is the maximum continuous drain current rating for RJK4512DPP-00#T2?
The RJK4512DPP-00#T2 has a maximum continuous drain current (ID) of 14 A at case temperature Tc = 25°C. This rating assumes proper heatsinking and derates linearly with increasing case temperature - at 100°C case temperature, the usable ID drops to approximately 7.5 A per the Safe Operating Area curve in the official datasheet.
Does RJK4512DPP-00#T2 have an integrated body diode, and what are its key parameters?
Yes, the RJK4512DPP-00#T2 includes an integrated body-drain diode with forward voltage VDF = 0.89 V (typ.) at 14 A and reverse recovery time trr = 280 ns under di/dt = 100 A/µs. These values are measured with VGS = 0 and are critical for designing snubberless flyback or freewheeling paths in inductive switching circuits.
What is the gate threshold voltage range for RJK4512DPP-00#T2, and how does it affect drive requirements?
The RJK4512DPP-00#T2 has a gate-to-source cutoff voltage (VGS(off)) range of 3.0–4.5 V at ID = 1 mA. This ensures full enhancement with standard 10 V gate drive while providing noise margin against spurious turn-on - unlike logic-level MOSFETs, it is not intended for direct 3.3 V or 5 V MCU GPIO drive without level shifting.
Is RJK4512DPP-00#T2 suitable for avalanche-rated applications, and what is its rated avalanche energy?
Yes, the RJK4512DPP-00#T2 is characterized for single-pulse avalanche operation with an energy rating EAR = 0.5 mJ at Tch ≤ 150°C. This makes it suitable for unclamped inductive switching in relay drivers or solenoid controls, provided pulse conditions meet the datasheet's STch = 25°C test condition and current limits.
What package type does RJK4512DPP-00#T2 use, and what are its thermal characteristics?
The RJK4512DPP-00#T2 uses the TO-220FN package (RENESAS code PRSS0003AB-A), featuring an insulated tab and 4.17 °C/W channel-to-case thermal impedance. This allows 30 W channel dissipation with ≤125°C temperature rise from case to channel - essential for sustained high-current operation in compact industrial power modules.
