Product details

Overview

2SK2869-92STR from Renesas is an N-channel enhancement-mode MOSFET designed for high-speed power switching in DC-DC converters and motor drivers. It features 60 V V_DSS, 20 A continuous drain current, 0.033 Ω typical R_DS(on) at V_GS = 10 V, and 4 V gate threshold compatibility with 5 V logic systems.

For engineers reviewing the 2SK2869-92STR datasheet, 2SK2869-92STR pinout, 2SK2869-92STR application, or 2SK2869-92STR equivalent, key selection criteria include avalanche energy rating (34 mJ), body diode reverse recovery time (40 ns), and DPAK(S) package thermal resistance for high-current pulsed operation.

Technical Context

This MOSFET employs a planar silicon process optimized for low conduction loss and fast switching transients. Its gate charge profile supports efficient drive with standard 5 V microcontroller outputs, and its body diode exhibits controlled reverse recovery behavior suitable for synchronous rectification.

The device operates within a channel temperature range of –55°C to +150°C and is rated for repetitive avalanche energy up to 34 mJ at T_ch = 25°C with R_g ≥ 50 Ω - enabling robustness in inductive load switching without external snubbers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFZ44NPBF	R_DS(on) = 0.028 Ω at V_GS = 10 V; V_DSS = 55 V; TO-220 package	Larger footprint and higher thermal resistance (θ_JC = 1.5°C/W); no avalanche rating specified	Prefer when lower R_DS(on) is critical and board space allows through-hole mounting
STP20NK60ZFP	V_DSS = 600 V; R_DS(on) = 0.33 Ω; SuperMESH™ technology; TO-220FP package	Designed for high-voltage SMPS, not optimized for 24–48 V switching; higher conduction loss	Select only if system requires >100 V blocking capability and can tolerate higher R_DS(on)

Compared with IRFZ44NPBF and STP20NK60ZFP, the 2SK2869-92STR uniquely balances 60 V rating, 0.033 Ω R_DS(on), 34 mJ avalanche capability, and DPAK(S) thermal performance - making it optimal for compact, high-reliability 24–48 V industrial switching where layout area and transient robustness are constrained.

FAQ

What is the gate threshold voltage range for the 2SK2869-92STR?

The 2SK2869-92STR has a gate-to-source cutoff voltage (V_GS(off)) of 1.5–2.5 V at I_D = 1 mA and V_DS = 10 V. This ensures reliable enhancement with standard 4–5 V logic-level gate drive, and the device achieves full conduction at V_GS = 4 V with R_DS(on) = 0.055 Ω typ. The 2SK2869-92STR is therefore well-suited for direct interface with 5 V microcontrollers without level-shifting circuitry.

Does the 2SK2869-92STR have avalanche capability, and how is it rated?

Yes, the 2SK2869-92STR is rated for repetitive avalanche operation with E_AR = 34 mJ at T_ch = 25°C and R_g ≥ 50 Ω. This rating is measured under standardized avalanche test conditions (V_DD = 25 V, I_AP = 20 A, duty < 0.1 %) and allows the 2SK2869-92STR to safely absorb inductive energy during switching transients - eliminating the need for external clamping components in relay or motor drive designs.

What package type does the 2SK2869-92STR use, and what are its thermal characteristics?

The 2SK2869-92STR uses the DPAK(S) surface-mount package (RENESAS code PRSS0004ZD-C, JEITA SC-63), with an exposed drain tab for thermal conduction. Its junction-to-case thermal resistance θ_JC is 4.17°C/W, enabling 30 W channel dissipation at T_c = 25°C. The 2SK2869-92STR's 0.28 g mass and compact 6.5 mm × 3.1 mm footprint support high-density PCB layouts in space-constrained power stages.

How does the body diode performance of the 2SK2869-92STR compare to standard MOSFETs?

The 2SK2869-92STR features a fast body diode with reverse recovery time t_rr = 40 ns at I_F = 20 A and di_F/dt = 50 A/µs. Its forward voltage V_DF is 1.0 V at I_F = 20 A, indicating low conduction loss during freewheeling. This performance makes the 2SK2869-92STR suitable for synchronous rectification and half-bridge topologies where diode recovery impacts efficiency and EMI - unlike many general-purpose MOSFETs lacking characterized t_rr.

Can the 2SK2869-92STR be driven directly from a 5 V microcontroller GPIO pin?

Yes, the 2SK2869-92STR is explicitly characterized for 4 V gate drive, achieving R_DS(on) = 0.055 Ω typ. at V_GS = 4 V and I_D = 10 A. With a gate threshold range of 1.5–2.5 V and low gate charge (Q_g ≈ 30 nC per datasheet curves), it can be switched efficiently by most 5 V MCUs - though a dedicated gate driver is recommended for >50 kHz operation to minimize switching losses. The 2SK2869-92STR thus simplifies drive circuitry in cost-sensitive industrial controls.
