Product details
Overview
2SJ495-S12-AZ from Renesas Electronics is a P-channel enhancement-mode power MOSFET designed for high-current DC switching in industrial power supplies and motor control circuits. It delivers RDS(on) = 30 mΩ max at VGS = –10 V and ID = –15 A, supports –60 V drain-source voltage, and features integrated gate protection diode. Its MP-45F (isolated TO-220) package enables robust thermal management in 24 V/48 V bus systems.
For engineers reviewing the 2SJ495-S12-AZ datasheet, 2SJ495-S12-AZ pinout, 2SJ495-S12-AZ application, or 2SJ495-S12-AZ equivalent, key selection criteria include verified RDS(on) at –4 V gate drive, body diode reverse recovery charge (Qrr = 400 nC), safe operating area under pulsed load conditions, and thermal resistance Rth(ch-c) = 3.57 °C/W for heatsink-limited designs.
Technical Context
This device operates as a low-side switch in buck converters, H-bridge half-bridges, and battery protection circuits. Its negative threshold voltage (VGS(off) = –1.0 to –2.0 V) ensures reliable turn-off with standard logic-level gate drivers, while its high input capacitance (Ciss = 4120 pF typ.) necessitates careful gate driver sizing for <220 ns rise time.
The built-in gate-source ESD protection diode reduces external component count but does not eliminate need for external transient suppression. Its forward transfer admittance |yfs| = 12–24 S confirms strong transconductance for fast current regulation, and QG = 140 nC at ID = –30 A defines minimum gate driver peak current requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | –60 V - Maximum blocking voltage in high-side or synchronous rectifier configurations |
| RDS(on)1 | 30 mΩ max @ VGS = –10 V, ID = –15 A - Enables <0.7 W conduction loss at rated DC current |
| ID(DC) | –30 A - Continuous drain current rating with case temperature ≤ 25°C and adequate heatsinking |
| QG | 140 nC - Total gate charge defining minimum driver energy per switching cycle |
| Rth(ch-c) | 3.57 °C/W - Channel-to-case thermal resistance enabling 35 W dissipation with 125°C channel limit |
| Qrr | 400 nC - Reverse recovery charge of intrinsic body diode affecting cross-conduction losses in bridge topologies |
| VF(S-D) | 0.8–1.5 V @ IF = 30 A - Forward voltage drop of source-drain body diode during freewheeling |
Pinout & Package
2SJ495-S12-AZ uses the MP-45F package - an isolated TO-220 variant with electrically insulated tab, allowing direct mounting to heatsinks without insulating washers. The package complies with JEDEC TO-220AB mechanical standards and provides 15.0 mm × 12.0 mm footprint with 13.5 mm minimum height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives negative gate voltage relative to source to modulate channel conductivity; requires ESD-safe handling |
| 2 (Drain) | High-side current terminal | Connected to negative rail or load return path; electrically isolated from tab in MP-45F package |
| 3 (Source) | Reference terminal | Serves as common reference for gate drive and current sensing; tied to system ground in low-side switch configuration |
Key Features
| Feature | Design Value |
|---|---|
| Super low RDS(on) at –4 V drive | RDS(on)2 = 56 mΩ max enables compatibility with 5 V logic-level controllers without level-shifting |
| Built-in gate protection diode | Integrated Zener-rated gate-source diode suppresses ±20 V AC transients, reducing external TVS count |
| High pulsed current capability | ID(pulse) = –120 A (PW ≤ 10 µs) supports short-circuit withstand in motor stall or overload events |
| Low output capacitance | COSS = 1750 pF typ. minimizes Miller-effect-induced switching delay in high-frequency PWM stages |
| Robust SOA at elevated temperature | Forward bias SOA curve validated up to Tch = 150°C supports operation in sealed industrial enclosures |
Applications

Use Scenario: Cell-balancing discharge switch in 16-cell Li-ion battery pack for material handling equipment. IC Role / Device Role / Timing Role: Precision-controlled shunt path activated during constant-voltage charging phase to equalize cell voltages. Use Value: RDS(on) stability over –55 to +150°C ensures consistent balancing current across environmental extremes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTP10P60P | RDS(on) = 550 mΩ @ –10 V; higher VDSS = –600 V; TO-220 non-isolated | Designed for high-voltage flyback snubbers, not optimized for low-VDS conduction efficiency | Select when >400 V blocking required; avoid for 48 V systems due to excessive conduction loss |
| IRF9540NPBF | RDS(on) = 200 mΩ @ –10 V; same MP-45F package; no built-in gate protection diode | Legacy industrial replacement with lower cost but requires external gate clamping | Acceptable where gate drive is well-regulated and layout minimizes ringing; verify ESD robustness in final assembly |
Compared with IXTP10P60P and IRF9540NPBF, the 2SJ495-S12-AZ offers superior conduction efficiency below 60 V and integrated gate protection - critical for field-replaceable modules where layout constraints limit external protection components.

FAQ
What is the maximum continuous drain current rating for the 2SJ495-S12-AZ under real-world PCB heatsinking conditions?
The 2SJ495-S12-AZ is rated for ID(DC) = –30 A at TC = 25°C with infinite heatsink. Under typical 2-layer PCB with 10 cm² copper pour and 1 mm thermal via array, derating to –18 A is recommended to maintain Tch ≤ 125°C. Actual current depends on ambient temperature, airflow, and heatsink interface resistance - the 2SJ495-S12-AZ datasheet provides SOA curves for precise boundary calculation.
Does the 2SJ495-S12-AZ have a built-in body diode, and what are its key conduction parameters?
Yes, the 2SJ495-S12-AZ integrates a source-drain body diode with VF(S-D) = 0.8–1.5 V at IF = 30 A and reverse recovery time trr = 160 ns. Its Qrr = 400 nC at di/dt = 100 A/µs defines switching loss contribution in synchronous rectification or freewheeling paths - critical for evaluating efficiency in buck or half-bridge topologies using the 2SJ495-S12-AZ.
Can the 2SJ495-S12-AZ be driven directly from a 3.3 V microcontroller GPIO without level shifting?
No. The 2SJ495-S12-AZ requires VGS ≤ –4 V for guaranteed RDS(on) ≤ 56 mΩ and full enhancement. A 3.3 V GPIO cannot produce negative gate voltage relative to source. Driving the 2SJ495-S12-AZ directly would result in weak conduction (RDS(on) > 200 mΩ) and thermal runaway. A dedicated negative gate driver or level-shifting circuit is mandatory for proper 2SJ495-S12-AZ operation.
What is the meaning of "S12-AZ" suffix in the 2SJ495-S12-AZ part number?
The "S12-AZ" suffix denotes Renesas' internal packaging and marking variant: "S12" specifies MP-45F (isolated TO-220) leadframe plating and mold compound, while "AZ" indicates tape-and-reel packaging per JIS C 0806 with 50 pcs/reel and RoHS-compliant finish. This distinguishes it from bulk-packaged or non-isolated variants like 2SJ495-Z.
How does the gate protection diode in the 2SJ495-S12-AZ function, and what external protection is still required?
The 2SJ495-S12-AZ includes an internal Zener diode between gate and source rated for ±20 V AC and –20 V DC. It clamps ESD transients but does not protect against sustained overvoltage or fast-rising inductive spikes. External gate resistors (10–47 Ω), RC snubbers, and TVS diodes remain necessary for robust operation in motor drive or relay-switching applications where the 2SJ495-S12-AZ may experience >10 V/ns dv/dt.
