Product details
Overview
2SJ245L-E from Renesas Electronics (formerly Hitachi) is a silicon P-channel enhancement-mode MOSFET designed for high-speed power switching in DC-DC converters and switching regulators. It features –60 V VDSS, –5 A continuous drain current, 0.25 Ω RDS(on) at VGS = –10 V, 4 V gate threshold compatibility with 5 V logic, and 20 W channel dissipation at TC = 25°C.
For engineers reviewing the 2SJ245L-E datasheet, 2SJ245L-E pinout, 2SJ245L-E application, or 2SJ245L-E equivalent, key selection criteria include its low on-resistance at low gate drive, fast switching times (td(on) = 12 ns, tf = 90 ns), body diode recovery performance (trr = 160 ns), and DPAK-1 package thermal capability for compact power stage layouts.
Technical Context
This P-channel MOSFET operates as a high-side switch in non-synchronous buck and flyback topologies. Its –2.0 V maximum VGS(off) ensures reliable turn-off with standard 5 V microcontroller outputs, while the 0.28 Ω RDS(on) at VGS = –4 V enables efficient operation without level-shifting circuitry.
The device integrates a built-in body diode with –1.1 V forward voltage at –5 A and 160 ns reverse recovery time, supporting freewheeling paths in inductive switching applications. Its Ciss = 610 pF and Crss = 95 pF support stable gate drive design with minimal Miller-induced oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | –60 V - supports input rails up to 48 V DC-DC systems with margin |
| ID (continuous) | –5 A - handles typical mid-power converter output stages |
| RDS(on) @ VGS = –10 V | 0.25 Ω - delivers ≤0.625 W conduction loss at 5 A |
| RDS(on) @ VGS = –4 V | 0.38 Ω - enables direct 5 V MCU gate drive without boost |
| tr/tf | 45 ns / 90 ns - supports >1 MHz switching in optimized layouts |
| trr | 160 ns - limits diode recovery losses in hard-switched topologies |
| Pch @ TC = 25°C | 20 W - allows 2.5× derating to 8 W at 100°C case temperature |
Pinout & Package
2SJ245L-E uses the surface-mount DPAK-1 (TO-252-1) package with exposed drain pad for thermal management. Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source, Pin 4 = Drain (common drain connection between pins 2 and 4).

|---|---|---|
| 1 (G) | Gate | Control terminal; accepts –4 V to –20 V drive for full enhancement |
| 2 (D) | Drain | Main high-side power path; electrically tied to pin 4 |
| 3 (S) | Source | Reference node for gate drive; connects to input rail in high-side config |
| 4 (D) | Drain (redundant) | Secondary drain connection; improves current sharing and thermal spreading |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4 V drive | 0.38 Ω enables direct interface with 5 V logic without gate driver ICs |
| Fast switching speed | 12 ns turn-on delay + 90 ns fall time supports >1 MHz operation |
| Integrated body diode | –1.1 V VDF at –5 A and 160 ns trr reduces external component count |
| Thermally robust package | DPAK-1 with exposed drain pad achieves θJC = 6.25 °C/W |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF9540NPBF | Higher RDS(on) (0.2 Ω @ –10 V but 0.55 Ω @ –5 V); TO-220 package; slower tr = 120 ns | Requires heatsink in same power class; unsuitable for space-constrained SMT designs | Select when through-hole mounting and higher voltage margin (–100 V) are prioritized over size and speed |
| Si2305DS-T1-E3 | Lower voltage rating (–30 V); smaller SOT-23 package; RDS(on) = 0.055 Ω @ –4.5 V but only rated for –4.1 A | Limited to sub-10 W loads; not suitable for 48 V input systems | Select for ultra-compact low-power applications where board area is critical and voltage stress is <30 V |
Compared with IRF9540NPBF and Si2305DS-T1-E3, the 2SJ245L-E uniquely balances –60 V rating, DPAK-1 SMT footprint, 0.38 Ω on-resistance at 5 V drive, and 160 ns body diode recovery-making it optimal for mid-power, space-constrained, high-efficiency DC-DC stages.

FAQ
What is the gate threshold voltage range for the 2SJ245L-E?
The 2SJ245L-E has a gate-to-source cutoff voltage (VGS(off)) ranging from –1.0 V to –2.0 V, measured at ID = –1 mA and VDS = –10 V. This ensures full turn-on with standard 5 V logic-level signals and provides noise immunity against false triggering in noisy industrial environments. The 2SJ245L-E reliably conducts at VGS ≤ –2.0 V and remains fully off above –1.0 V under typical operating conditions.
Can the 2SJ245L-E be used with 3.3 V microcontroller GPIOs?
No-the 2SJ245L-E requires a minimum of –4 V gate drive to achieve specified RDS(on) (0.38 Ω), and its VGS(off) upper limit is –1.0 V. A 3.3 V MCU output cannot produce sufficient negative gate-source potential; level-shifting or gate driver circuitry is required. The 2SJ245L-E is optimized for 5 V logic interfaces, not 3.3 V systems.
What is the maximum continuous drain current for the 2SJ245L-E at 100°C case temperature?
At TC = 100°C, the 2SJ245L-E's channel dissipation derates to approximately 8 W (from 20 W at 25°C), limiting continuous drain current to about –3.2 A assuming 0.25 Ω RDS(on). This value is derived from the published power vs. temperature derating curve and must be validated with actual PCB thermal design. The 2SJ245L-E datasheet specifies –5 A only at TC = 25°C.
Does the 2SJ245L-E have avalanche rating information in its datasheet?
No-avalanche energy rating (EAS) is not specified in the official 2SJ245L-E datasheet. The device is characterized for repetitive unclamped inductive switching only within its Safe Operating Area (SOA) limits. Designers must ensure voltage transients remain within the –60 V VDSS rating using snubbers or clamping circuits, as the 2SJ245L-E lacks guaranteed avalanche ruggedness.
How does the body diode performance of the 2SJ245L-E compare to Schottky alternatives?
The 2SJ245L-E body diode has VDF = –1.1 V at –5 A and trr = 160 ns-higher forward drop and slower recovery than discrete Schottky diodes (e.g., ~0.45 V, <10 ns). However, it eliminates external component count and layout area. For high-frequency, low-loss designs, a Schottky parallel diode may be added-but the 2SJ245L-E's integrated diode suffices for ≤500 kHz flyback or buck applications where efficiency trade-offs are acceptable.
