Product details
Overview
RJK4512DPP-K0#T2 from Renesas is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and motor drive circuits, featuring 450 V VDSS, 0.43 Ω typical RDS(on) at VGS = 10 V, 14 A continuous drain current, and TO-220FN package with isolated heatsink tab.
For engineers reviewing the RJK4512DPP-K0#T2 datasheet, RJK4512DPP-K0#T2 pinout, RJK4512DPP-K0#T2 application, or RJK4512DPP-K0#T2 equivalent, key selection criteria include avalanche energy rating (0.5 mJ), fast switching times (td(off) = 78 ns), body-diode reverse recovery time (280 ns), and thermal impedance (θch-c = 4.17 °C/W).
Technical Context
This MOSFET employs planar vertical DMOS structure optimized for ruggedness in hard-switched topologies. Its gate threshold voltage range (3.0–4.5 V) ensures reliable turn-on with standard 10 V gate drivers while maintaining low leakage (IDSS ≤ 1 µA at 450 V).
The device integrates a co-packaged body diode with VDF = 0.89 V (typ.) at 14 A and trr = 280 ns under specified di/dt conditions, enabling use in freewheeling paths without external diode addition in moderate-frequency SMPS designs.
Key Specifications

|---|---|
| VDSS | 450 V - supports 380 V AC rectified bus applications with 15% margin |
| RDS(on) | 0.43 Ω (typ.) at ID = 7 A, VGS = 10 V - enables <1.5 W conduction loss at 7 A |
| Qg | 29 nC - determines gate drive power requirement and switching loss trade-off |
| td(off) | 78 ns - sets minimum off-time limit in PWM controllers operating above 1 MHz |
| θch-c | 4.17 °C/W - defines heatsink sizing for 30 W Pch dissipation at Tc = 25°C |
| trr | 280 ns - constrains maximum operating frequency in discontinuous conduction mode flyback |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP4NK50ZFP | 500 V VDSS, 1.5 Ω RDS(on), TO-220FP package (non-isolated tab) | Higher RDS(on) increases conduction loss; non-isolated tab requires insulator | Preferred where higher voltage margin is critical and thermal budget allows higher on-resistance |
| IXTH12N50L | 500 V VDSS, 0.55 Ω RDS(on), TO-247 package, lower Qg (22 nC) | Larger footprint; lower gate charge improves high-frequency efficiency | Selected when layout space permits TO-247 and switching frequency exceeds 300 kHz |
Compared with STP4NK50ZFP and IXTH12N50L, the RJK4512DPP-K0#T2 offers optimal balance of 450 V rating, 0.43 Ω on-resistance, and TO-220FN isolation-making it especially suitable for space-constrained industrial SMPS where thermal interface simplicity and mid-frequency efficiency are prioritized.

FAQ
What is the maximum continuous drain current rating for RJK4512DPP-K0#T2?
The RJK4512DPP-K0#T2 has a continuous drain current (ID) rating of 14 A at Tc = 25°C, limited by its safe operating area and thermal resistance. This rating assumes proper heatsinking to maintain channel temperature below 150°C. At elevated case temperatures, derating is required per the datasheet's ID vs. Tc curve.
Does RJK4512DPP-K0#T2 have an integrated body diode, and what are its key parameters?
Yes, the RJK4512DPP-K0#T2 includes an integral body-drain diode with forward voltage VDF = 0.89 V (typ.) at 14 A and reverse recovery time trr = 280 ns under specified test conditions (diF/dt = 100 A/µs). This diode supports freewheeling in inductive switching applications but is not optimized for high-frequency synchronous rectification.
What is the gate-to-source voltage rating for RJK4512DPP-K0#T2, and why does it matter?
The RJK4512DPP-K0#T2 specifies ±30 V for VGS, meaning the gate can tolerate up to +30 V for turn-on and –30 V for active pull-down without damage. Exceeding this risks oxide breakdown. This rating informs gate driver selection-especially in noisy environments where negative voltage clamping may be needed to prevent spurious turn-on.
How does the TO-220FN package of RJK4512DPP-K0#T2 differ from standard TO-220?
The TO-220FN package used by RJK4512DPP-K0#T2 features an electrically isolated metal tab, unlike standard TO-220. This allows direct mounting to a grounded heatsink without insulating hardware, reducing thermal resistance and assembly complexity. The "FN" suffix denotes this isolation feature per Renesas' package coding system.
Can RJK4512DPP-K0#T2 be used in avalanche-mode operation, and what is its rated energy?
Yes, the RJK4512DPP-K0#T2 is rated for single-pulse avalanche operation with EAR = 0.5 mJ at Tch = 25°C. This capability allows controlled energy dissipation during inductive switching transients, such as those occurring in relay driving or unclamped inductive loads-but repeated avalanche stress is not recommended and must be validated per application conditions.
