Renesas 2SJ599(0)-ZK-E1-AY

Overview

2SJ599(0)-ZK-E1-AY from Renesas Electronics is a P-channel enhancement-mode power MOSFET designed for high-current switching in solenoid, motor, and lamp driver circuits. It delivers R_DS(on)1 = 75 mΩ max at V_GS = –10 V and I_D = –10 A, supports –60 V drain-to-source voltage, handles –20 A DC drain current (T_C = 25°C), and features built-in gate protection diode for ESD robustness.

For engineers reviewing the 2SJ599(0)-ZK-E1-AY datasheet, 2SJ599(0)-ZK-E1-AY pinout, 2SJ599(0)-ZK-E1-AY application, or 2SJ599(0)-ZK-E1-AY equivalent, key selection criteria include low-voltage gate drive capability (R_DS(on)2 = 111 mΩ max at V_GS = –4.0 V), avalanche energy rating (E_AS = 40 mJ), and TO-252 (MP-3Z) surface-mount package suitability for thermally demanding industrial drivers.

Technical Context

This device operates as a single N-channel depletion-mode MOSFET is incorrect - it is a P-channel enhancement-mode device requiring negative gate bias relative to source to conduct. Its gate threshold voltage range (V_GS(off) = –1.5 to –2.5 V) enables reliable turn-on with standard logic-level negative drive, while its 1300 pF input capacitance (C_iss) and 26 nC total gate charge support fast switching up to 100 kHz in hard-switched topologies.

The integrated body diode exhibits V_F(S-D) = 1.0 V at I_F = 20 A and t_rr = 51 ns, making it suitable for freewheeling in inductive loads without external diode supplementation. Its rated single-pulse avalanche capability (I_AS = –20 A, E_AS = 40 mJ) provides design margin against inductive kickback in solenoid and motor control applications.

Key Specifications

Pinout & Package

2SJ599(0)-ZK-E1-AY is packaged in TO-252 (MP-3Z), a surface-mount power package with exposed drain pad for enhanced thermal dissipation. The case outline matches JEDEC TO-252-3 standard, with pin 1 (Gate), pin 2 (Drain), and pin 3 (Source) arranged linearly; the drain tab (pin 2 and fin) is electrically connected to the drain terminal and serves as primary heat path to PCB copper.

FAQ

What is the maximum continuous drain current rating for the 2SJ599(0)-ZK-E1-AY?

The 2SJ599(0)-ZK-E1-AY is rated for –20 A DC drain current at case temperature T_C = 25°C. This rating assumes adequate PCB copper area for heat dissipation; derating applies above 25°C case temperature per the published thermal resistance curve (R_th(j-c) = 3.57°C/W). At elevated temperatures or with limited copper, the usable current must be reduced accordingly to maintain channel temperature below 150°C.

Does the 2SJ599(0)-ZK-E1-AY have built-in ESD protection?

Yes, the 2SJ599(0)-ZK-E1-AY integrates a gate-to-source protection diode explicitly described in the datasheet's equivalent circuit diagram. This diode safeguards the gate oxide from electrostatic discharge events, though Renesas recommends adding external protection if voltages exceeding ±20 V may appear on the gate terminal during system operation.

Can the 2SJ599(0)-ZK-E1-AY be driven directly by a 3.3 V microcontroller GPIO?

No - the 2SJ599(0)-ZK-E1-AY is a P-channel enhancement MOSFET requiring a negative gate-to-source voltage to turn on. A 3.3 V GPIO alone cannot produce the necessary –4.0 V or –10 V bias. It must be paired with a level-shifting circuit (e.g., complementary NPN/PNP driver or dedicated gate driver IC) to generate the required negative gate drive relative to the source node.

What is the avalanche energy rating of the 2SJ599(0)-ZK-E1-AY and how is it tested?

The 2SJ599(0)-ZK-E1-AY is rated for 40 mJ single-pulse avalanche energy (E_AS) under test conditions of V_DD = –30 V, I_AS = –20 A, R_G = 25 Ω, and V_GS transitioning from –20 V to 0 V, starting from T_ch = 25°C. This rating is verified per JEDEC JESD24-1 and enables reliable operation in inductive switching without external snubbers.

Is the 2SJ599(0)-ZK-E1-AY RoHS compliant?

Yes, the 2SJ599(0)-ZK-E1-AY complies with the EU RoHS Directive. Renesas Electronics confirms RoHS compliance for this part in the official product change notices and material declarations associated with the D14644EJ4V0DS00 datasheet revision. Lead-free soldering profiles compatible with Pb-free assembly are supported per JEDEC J-STD-020.
