Renesas 2SJ605-ZJ-E1-AZ

Overview

2SJ605-ZJ-E1-AZ from Renesas Electronics is a P-channel power MOSFET designed for high-current industrial switching applications, featuring R_DS(on)1 = 20 mΩ max at V_GS = –10 V and I_D = –33 A, avalanche energy rating E_AS = 203 mJ, and TO-263 (MP-25ZJ) surface-mount package with integral drain-fin thermal path. It serves as a main-side switch in DC-DC converters, motor drive H-bridge high-side legs, and battery protection circuits.

For engineers reviewing the 2SJ605-ZJ-E1-AZ datasheet, 2SJ605-ZJ-E1-AZ pinout, 2SJ605-ZJ-E1-AZ application, or 2SJ605-ZJ-E1-AZ equivalent, key selection criteria include guaranteed low R_DS(on) at –4 V gate drive, built-in gate protection diode, single-pulse avalanche capability up to –45 A, and thermal resistance R_th(ch–C) = 1.25 °C/W for high-power density board designs.

Technical Context

This device employs a vertical double-diffused MOS (VDMOS) structure optimized for low conduction loss and robust unclamped inductive switching (UIS) performance. Its gate threshold voltage V_GS(off) ranges from –1.5 V to –2.5 V, enabling reliable turn-on with standard logic-level negative gate drivers.

The integrated body diode exhibits t_rr = 53 ns and Q_rr = 110 nC under I_F = 65 A, supporting synchronous rectification and freewheeling in hard-switched topologies. The 4600 pF input capacitance (C_iss) and 87 nC total gate charge (Q_G) define its drive strength requirements for <100 ns switching transitions.

FAQ

What is the maximum continuous drain current rating for the 2SJ605-ZJ-E1-AZ at case temperature of 100°C?

The 2SJ605-ZJ-E1-AZ supports I_D(DC) = –65 A at T_C = 25°C, but derates linearly above that temperature. At T_C = 100°C, the maximum continuous drain current is approximately –35 A, based on the derating curve in Figure 2 of the datasheet D14650EJ2V0DS. This value assumes proper PCB copper area and thermal via design per the TO-263 footprint recommendations. Always verify thermal performance in final layout using the 2SJ605-ZJ-E1-AZ's R_th(ch–C) = 1.25 °C/W.

Does the 2SJ605-ZJ-E1-AZ have a specified avalanche energy rating, and how is it tested?

Yes, the 2SJ605-ZJ-E1-AZ has a single-pulse avalanche energy rating E_AS = 203 mJ, measured under conditions of V_DD = –30 V, R_G = 25 Ω, and starting channel temperature T_ch = 25°C, with gate drive transitioning from –20 V to 0 V. This rating is validated per JEDEC JESD24-1 and confirms the device's ability to absorb inductive energy without failure during unclamped inductive switching events. The 2SJ605-ZJ-E1-AZ's E_AS is explicitly listed in the Absolute Maximum Ratings table.

Can the 2SJ605-ZJ-E1-AZ be driven directly by a microcontroller GPIO pin?

No - the 2SJ605-ZJ-E1-AZ requires a negative gate-source voltage (V_GS) up to –10 V for full enhancement and has a gate threshold range of –1.5 V to –2.5 V. A standard 3.3 V or 5 V microcontroller GPIO cannot provide the necessary negative bias or sufficient current (Q_G = 87 nC). Driving the 2SJ605-ZJ-E1-AZ requires a dedicated negative gate driver IC or level-shifting circuit capable of sinking ≥2 A peak current and delivering –10 V to ensure reliable, fast switching without shoot-through.

What is the thermal resistance from channel to case (R_th(ch–C)) for the 2SJ605-ZJ-E1-AZ, and how does it impact heatsinking?

The 2SJ605-ZJ-E1-AZ has R_th(ch–C) = 1.25 °C/W when mounted per the TO-263 (MP-25ZJ) package recommendations - including full-solder coverage of the drain fin to ≥2 oz copper with thermal vias. This low value means a 50 W power dissipation raises the channel temperature only 62.5°C above case temperature. Effective heatsinking relies on minimizing the interface resistance between the PCB copper and external heatsink; the 2SJ605-ZJ-E1-AZ's design eliminates the need for mechanical mounting hardware typical of TO-220 devices.

Is the body diode of the 2SJ605-ZJ-E1-AZ suitable for synchronous rectification in a buck converter?

The 2SJ605-ZJ-E1-AZ's body diode has t_rr = 53 ns and Q_rr = 110 nC at I_F = 65 A, indicating moderately fast and soft recovery - acceptable for ≤200 kHz buck converters with careful gate timing. However, its forward voltage V_F(S–D) = 1.0 V at 65 A is higher than discrete Schottky diodes, resulting in greater conduction loss during freewheeling. For optimal efficiency, the 2SJ605-ZJ-E1-AZ is best used in complementary high-side switching roles rather than relying solely on its body diode for rectification.
