Product details
Overview
2SJ325-Z-AY from Renesas Electronics is a P-channel power MOSFET designed for low-voltage switching in solenoid, motor, and lamp driver circuits. It delivers RDS(on) = 0.08 Ω (typ.) at VGS = −10 V and ID = −2.0 A, supports −30 V drain-source voltage, −4.0 A DC drain current, and features built-in gate-source protection diode.
For engineers reviewing the 2SJ325-Z-AY datasheet, 2SJ325-Z-AY pinout, 2SJ325-Z-AY application, or 2SJ325-Z-AY equivalent, key selection criteria include guaranteed RDS(on) at low gate drive (−4 V), TO-252 package thermal performance, and suitability for 24 V industrial load switching with pulse current capability up to −16 A.
Technical Context
This device operates as a single N-channel enhancement-mode MOSFET in depletion configuration - no; it is explicitly a P-channel enhancement-mode device requiring negative gate bias relative to source. Its low input capacitance (Ciss = 800 pF typ.) enables fast switching in PWM-driven loads, while the integrated G-S protection diode suppresses transient-induced gate damage during inductive turn-off.
The TO-252 (MP-3Z) package provides exposed drain pad for enhanced thermal conduction to PCB copper, supporting 20 W total power dissipation at case temperature (TC = 25°C), though ambient-limited dissipation is only 1.0 W - indicating strict board-level heatsinking requirements for sustained operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −30 V: Maximum blocking voltage for 24 V nominal systems with surge margin. |
| RDS(on) (VGS = −10 V) | 0.08 Ω typ.: Enables <160 mW conduction loss at −2 A, critical for thermally constrained PCBs. |
| RDS(on) (VGS = −4 V) | 0.15 Ω typ.: Confirmed operation with logic-level gate drive from 5 V microcontrollers via level-shifting. |
| ID(pulse) | −16 A (PW ≤ 10 μs, duty ≤ 1%): Supports high peak current for solenoid pull-in or motor stall conditions. |
| Ciss | 800 pF typ.: Reduces gate drive power and speeds up switching transitions in 10–100 kHz PWM applications. |
| Tch | 150 °C max: Specifies absolute channel temperature limit; derating required above TA = 25°C per thermal resistance data. |
Pinout & Package
2SJ325-Z-AY uses the TO-252 (MP-3Z) surface-mount package with exposed drain pad for thermal management. The package has three main terminals plus an auxiliary drain fin for mechanical stability and improved heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives negative gate-source voltage to turn on; protected by internal Zener diode to ±20 V AC / −20/+10 V DC. |
| 2 (Drain) | Main current path output | Connected to high-side load return; electrically tied to exposed metal pad for thermal and electrical conduction. |
| 3 (Source) | Reference node / current return | Serves as circuit ground reference for gate drive; connects to system common or controller ground. |
| 4 (Drain Fin) | Mechanical/thermal extension | Not electrically isolated; enhances thermal coupling to PCB copper area without adding new signal path. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at −4 V | Enables direct interface with 5 V logic controllers without external level shifters in low-power drivers. |
| Built-in G-S protection diode | Eliminates need for external gate clamp diodes in inductive load applications like relay coils or DC motors. |
| TO-252 thermal design | Supports 20 W power handling when mounted on ≥10 cm² 2-oz copper with thermal vias - suitable for compact industrial modules. |
| −30 V VDSS rating | Provides 25 % headroom over standard 24 V supply rails, accommodating load dump transients in automotive-adjacent equipment. |
Applications
| Industrial Solenoid Control | DC Motor Direction Switching |

IC Role / Device Role / Timing Role: Reverse-polarity protected high-side switch enabling automatic failover between two supplies. Use Value: Integrated G-S diode blocks reverse current flow; −30 V rating accommodates input ripple and transient overshoot without external TVS. |
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 @ −10 V; TO-220 package; no integrated G-S diode. | Requires external gate protection; higher conduction loss limits use in thermally dense layouts. | Preferred where through-hole mounting and higher voltage margin (−100 V) are prioritized over thermal efficiency. |
| Si2305DS | RDS(on) = 0.045 Ω @ −4.5 V; SOT-23 package; 6 V max VGS; 2.8 A ID. | Lower current/power capability; unsuitable for >1 A continuous loads or >10 W dissipation. | Selected for space-constrained low-power logic-level switches where TO-252 footprint is prohibitive. |
Compared with IRF9540NPbF and Si2305DS, the 2SJ325-Z-AY uniquely balances TO-252 thermal performance, −4 V gate drive compatibility, and integrated protection - making it optimal for mid-power industrial switching where PCB area, thermal budget, and reliability co-constrain design.

FAQ
What is the maximum gate-source voltage rating for the 2SJ325-Z-AY?
The 2SJ325-Z-AY specifies a DC gate-source voltage rating of −20 V to +10 V and an AC rating of ±20 V. Exceeding these limits risks permanent gate oxide damage. The built-in gate-source Zener diode clamps transients but does not replace proper external gate drive design. Always verify gate drive circuit compliance with these ratings when using the 2SJ325-Z-AY in production designs.
Can the 2SJ325-Z-AY be used with 5 V microcontroller GPIO without level shifting?
Yes - the 2SJ325-Z-AY achieves RDS(on) = 0.15 Ω (typ.) at VGS = −4 V, enabling reliable turn-on with 5 V logic referenced to source. However, ensure the microcontroller's output can sink sufficient current to charge/discharge the 800 pF input capacitance quickly. For high-frequency PWM, a dedicated gate driver is still recommended to minimize switching losses in the 2SJ325-Z-AY.
What is the thermal resistance (RθJA) of the 2SJ325-Z-AY in its TO-252 package?
The datasheet does not specify RθJA directly, but ambient-limited power dissipation is rated at 1.0 W at TA = 25°C - implying RθJA ≈ 125 °C/W under standard JEDEC test conditions. Actual RθJA depends heavily on PCB copper area, via count, and airflow. For thermal design with the 2SJ325-Z-AY, refer to Renesas' MP-3Z layout guidelines and validate with IR thermography under worst-case load.
Does the 2SJ325-Z-AY have avalanche ruggedness rating?
No avalanche rating is specified in the official Renesas datasheet D18328EJ3V0DS for the 2SJ325-Z-AY. While the device may survive limited unclamped inductive switching events due to its −30 V VDSS margin, it is not characterized or guaranteed for repetitive avalanche operation. Use external flyback diodes or RC snubbers when switching inductive loads with the 2SJ325-Z-AY.
Is the 2SJ325-Z-AY RoHS compliant and lead-free?
Yes - the 2SJ325-Z-AY is RoHS compliant and lead-free, consistent with Renesas Electronics' environmental policy and EU Directive 2011/65/EU. The "-Z" suffix in the part number denotes lead-free packaging. Confirm compliance status using the latest Renesas Product Change Notification (PCN) for 2SJ325-Z-AY before high-volume deployment.
