Product details
Overview
2SJ325-AZ from Renesas Electronics is a P-channel enhancement-mode power MOSFET designed for low-frequency switching in solenoid, motor, and lamp driver circuits. It features RDS(on) = 0.08 Ω (typ, VGS = −10 V, ID = −2.0 A), −30 V VDSS, 4.0 A continuous drain current, TO-252 (MP-3Z) surface-mount package, and built-in gate-source protection diode.
For engineers reviewing the 2SJ325-AZ datasheet, 2SJ325-AZ pinout, 2SJ325-AZ application, or 2SJ325-AZ equivalent, this page provides verified electrical parameters, terminal mapping, real-world use cases in industrial load control, and validated alternative parts with documented functional differences.
Technical Context
The 2SJ325-AZ operates as a single N-channel depletion-mode device - correction: it is a P-channel enhancement-mode MOSFET with voltage-controlled conduction requiring negative gate bias relative to source. Its low Ciss of 800 pF (typ) supports moderate-speed switching up to ~100 kHz in non-resonant topologies.
Designed for DC/low-frequency AC load switching, it lacks integrated thermal shutdown or current limiting. Gate drive must supply ≥−10 V for full enhancement, and its 1.0 W ambient-rated power dissipation mandates external heatsinking above ~0.5 A continuous operation at room temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −30 V - Maximum reverse drain-source blocking voltage; defines safe operating range for 24 V DC systems with transient margin. |
| RDS(on) (VGS = −10 V) | 0.08 Ω typ - Enables ≤160 mW conduction loss at −2.0 A, suitable for thermally constrained PCB layouts. |
| ID(DC) | −4.0 A - Continuous DC current rating at TC = 25°C; derates to zero at TC = 150°C per SOA curve. |
| Ciss | 800 pF typ - Low input capacitance reduces gate drive power and enables simpler RC-based turn-on/turn-off timing. |
| PT2 (TA = 25°C) | 1.0 W - Ambient-limited power dissipation; requires copper pour or heatsink for >500 mA sustained loads. |
| Package | TO-252 (MP-3Z) - Surface-mount, 3-pin power package with exposed drain pad for thermal conduction to PCB. |
Pinout & Package
2SJ325-AZ uses the TO-252 (MP-3Z) package: a 3-terminal surface-mount outline with an exposed drain tab (pin 2 and 4 electrically connected). The package provides mechanical robustness and thermal path efficiency via soldered drain pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives negative gate-source voltage to enhance channel; requires ESD-safe handling and series gate resistor (10–100 Ω) for ringing suppression. |
| 2 & 4 (Drain) | High-side current return path | Electrically common terminals tied to exposed metal tab; must be connected to ground or low-impedance return plane for thermal and electrical performance. |
| 3 (Source) | Reference node for gate drive | Serves as return path for load current and reference for VGS; connects to positive rail in high-side switch configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at −10 V | 0.08 Ω typ enables <170 mW conduction loss at −2 A, reducing thermal stress in compact drivers. |
| Built-in G-S protection diode | Integrated Zener clamps gate-source voltage to ±20 V (AC) / −20 V +10 V (DC), eliminating need for external gate protection in basic designs. |
| Low input capacitance | 800 pF Ciss minimizes gate charge (Qg ≈ 12 nC, inferred from Ciss/VGS trend) and eases drive requirements from microcontroller GPIOs. |
| TO-252 thermal design | Exposed drain pad allows direct thermal coupling to PCB copper; achieves ~60°C/W junction-to-ambient with 1-in² 2-oz copper pour. |
Applications
| Automotive Interior Lighting Control | Industrial Solenoid Actuation |

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 |
|---|---|---|---|
| IRF9540NPbF | RDS(on) = 0.20 Ω (VGS = −10 V); TO-220 package; higher Ciss (1,200 pF) | Requires heatsink for >1.5 A; unsuitable for space-constrained SMT designs | Choose when board-level heatsinking is available and leaded assembly is preferred. |
| DMG2305UVT | RDS(on) = 0.045 Ω (VGS = −4.5 V); WDFN-6 package; no integrated G-S diode | Lower gate threshold enables 3.3 V MCU direct drive but requires external gate protection | Choose for ultra-low RDS(on) and 3.3 V logic compatibility; add 12 V Zener if gate voltage may exceed ±12 V. |
Compared with IRF9540NPbF and DMG2305UVT, the 2SJ325-AZ offers balanced RDS(on), integrated gate protection, and TO-252 thermal performance - making it optimal for cost-sensitive, medium-current industrial switching where SMT assembly and reliability under transient stress are priorities.

FAQ
What is the maximum continuous drain current rating for the 2SJ325-AZ?
The 2SJ325-AZ has a continuous drain current rating of −4.0 A at case temperature TC = 25°C. This rating decreases linearly with increasing case temperature, reaching zero at TC = 150°C. For ambient-operated conditions (TA = 25°C), the practical limit is 1.0 A due to its 1.0 W ambient power dissipation rating. Derating curves in the official Renesas datasheet D18328EJ3V0DS must be consulted for precise thermal design of the 2SJ325-AZ.
Does the 2SJ325-AZ include integrated gate protection?
Yes, the 2SJ325-AZ incorporates a built-in gate-source Zener diode for electrostatic discharge (ESD) protection. It limits gate-source voltage to ±20 V (AC) and −20 V/+10 V (DC), eliminating the need for external gate clamping components in most standard applications. This feature enhances system robustness during handling and operation, particularly in industrial environments where voltage transients are common - a key reliability attribute of the 2SJ325-AZ.
What package type does the 2SJ325-AZ use, and how is thermal management handled?
The 2SJ325-AZ uses the TO-252 (MP-3Z) surface-mount package, featuring an exposed drain pad (pins 2 and 4) that serves as the primary thermal conduction path. Effective thermal management requires soldering this pad to a large copper area on the PCB - typically ≥1 in² of 2-oz copper - achieving ~60°C/W junction-to-ambient. Without such layout, the 2SJ325-AZ's 1.0 W ambient power rating limits usable current well below its −4.0 A case-rated capability.
Can the 2SJ325-AZ be driven directly by a 3.3 V microcontroller GPIO?
No, the 2SJ325-AZ cannot be fully enhanced with 3.3 V gate drive. Its RDS(on) specification assumes VGS = −10 V, and at −4 V it rises to 0.15 Ω (typ). A 3.3 V GPIO lacks sufficient negative swing to achieve low-loss operation. To drive the 2SJ325-AZ reliably, a dedicated gate driver or level-shifter generating ≥−8 V is required - especially critical in high-current or thermally constrained applications where the 2SJ325-AZ's performance depends on proper gate bias.
Is the 2SJ325-AZ suitable for automotive applications?
The 2SJ325-AZ is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, and industrial robots - not automotive safety-critical systems. While it may function in non-safety automotive interior lighting, Renesas does not guarantee AEC-Q101 qualification or extended temperature operation (−40°C to +125°C) for the 2SJ325-AZ. For qualified automotive use, consult Renesas' AEC-Q101-compliant P-channel MOSFET portfolio instead of relying on the 2SJ325-AZ.
