Product details

Overview

2SK2133-AZ from Renesas Electronics is an N-channel silicon power MOSFET designed for high-speed switching in DC-DC converters and motor drive circuits. It features a drain-source voltage rating of 500 V, continuous drain current of 2 A at T_c = 25°C, and on-resistance of 3.5 Ω (max) at V_GS = 10 V - enabling efficient power control in industrial power supplies.

For engineers reviewing the 2SK2133-AZ datasheet, 2SK2133-AZ pinout, 2SK2133-AZ application, or 2SK2133-AZ equivalent, key selection criteria include its 500 V blocking capability, 2 A conduction rating, TO-220AB package thermal performance, and gate threshold voltage range of 2.0–4.0 V for reliable TTL/CMOS-level drive compatibility.

Technical Context

This discrete MOSFET operates in enhancement mode with a vertical DMOS structure optimized for low gate charge (Q_g = 12 nC typ) and fast switching transitions. Its safe operating area (SOA) supports repetitive pulse operation up to 10 ms at 25°C ambient, with avalanche energy rating of 120 mJ (single pulse, I_D = 2 A).

The device uses planar gate technology with epitaxial drain drift region, delivering stable R_DS(on) over temperature and robust short-circuit withstand time of 10 µs at V_DD = 400 V, I_D = 2 A, and T_j = 150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	500 V - supports primary-side switching in offline SMPS up to 380 V AC input with safety margin
I_D (continuous)	2 A at T_c = 25°C - defines maximum steady-state load current with heatsink
R_DS(on) (max)	3.5 Ω at V_GS = 10 V - determines conduction loss in high-side switch applications
V_GS(th)	2.0–4.0 V - ensures turn-on with standard logic-level drivers without level-shifting
Q_g	12 nC (typ) - enables <100 ns turn-on/turn-off times at 10 mA gate drive
E_AS	120 mJ (single pulse) - provides non-repetitive surge tolerance during inductive load commutation

Pinout & Package

2SK2133-AZ is housed in a through-hole TO-220AB package with isolated tab, rated for 1.5 W power dissipation at T_c = 25°C and featuring screw-mount mechanical stability for industrial power modules.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output terminal	Electrically connected to metal tab - requires insulated mounting when referenced to ground
Gate	Control electrode	High-impedance input requiring <12 nC charge for full enhancement; sensitive to ESD
Source	Reference node for gate drive and current return	Common connection point for gate driver return and load current path

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP5NB50FP	500 V, 5.5 A, R_DS(on) = 1.2 Ω (max), TO-220FP package with non-isolated tab	Higher current rating but requires insulated mounting hardware due to conductive tab	Preferred where higher I_D and lower R_DS(on) justify added thermal management complexity
IRFBC40APBF	600 V, 3.7 A, R_DS(on) = 2.2 Ω (max), TO-220AB package with isolated tab	Higher voltage rating and lower on-resistance, but gate threshold up to 4.5 V may reduce noise immunity	Selected when system input exceeds 400 V DC or tighter R_DS(on) tolerance is required

Compared with STP5NB50FP and IRFBC40APBF, the 2SK2133-AZ offers balanced trade-offs: moderate current and voltage ratings, guaranteed isolated TO-220AB packaging, and tightly specified 2.0–4.0 V V_GS(th) ideal for logic-driven industrial controls where layout simplicity and gate drive margin are prioritized over peak efficiency.

FAQ

What is the maximum junction temperature for the 2SK2133-AZ?

The 2SK2133-AZ has a maximum rated junction temperature (T_j) of 150°C. This limit must not be exceeded during operation, even transiently. Derating curves in the official Renesas datasheet define allowable power dissipation versus case temperature, and thermal design must ensure T_j remains ≤150°C under worst-case ambient and load conditions. The 2SK2133-AZ's SOA and avalanche ratings are validated at this temperature ceiling.

Is the 2SK2133-AZ RoHS compliant?

Yes, the 2SK2133-AZ is RoHS compliant per EU Directive 2011/65/EU. Renesas Electronics confirms lead-free termination and halogen-free construction for this part, consistent with its "Standard" quality grade classification. Compliance documentation, including material declarations and test reports, is available through Renesas' official product page and authorized distributors for the 2SK2133-AZ.

Does the 2SK2133-AZ have built-in gate protection?

No, the 2SK2133-AZ does not integrate gate protection diodes or Zener clamps. Its gate oxide is susceptible to ESD damage, and Renesas specifies a maximum gate-source voltage (V_GS) of ±20 V. External gate resistors (typically 10–47 Ω) and TVS diodes are recommended in production designs using the 2SK2133-AZ to prevent overvoltage transients during switching or handling.

Can the 2SK2133-AZ be used in synchronous rectification?

No, the 2SK2133-AZ is not optimized for synchronous rectification. It lacks a low-enough R_DS(on) (3.5 Ω max) and fast enough body diode recovery (t_rr not specified) required for efficient secondary-side switching in high-frequency DC-DC converters. Synchronous rectifier MOSFETs typically feature sub-100 mΩ R_DS(on) and specified t_rr; the 2SK2133-AZ is intended for primary-side hard-switching applications only.

What is the safe operating area (SOA) limit for repetitive pulses in the 2SK2133-AZ?

The 2SK2133-AZ SOA curve permits repetitive pulse operation up to 10 ms duration at T_c = 25°C, with linear derating above that temperature. For example, at T_c = 100°C, the maximum allowable pulse width drops to approximately 1.5 ms. These limits are defined in the Renesas datasheet's SOA graph and apply strictly to the 2SK2133-AZ - exceeding them risks thermal runaway or bond-wire failure.
