Product details

Overview

SUP28N15-52-E3 from Vishay Siliconix is a logic-level N-channel power MOSFET in TO-220AB package, rated for 150 V V_DS, 28 A continuous drain current at T_C = 25 °C, and 0.042 Ω R_DS(on) at V_GS = 10 V. It features repetitive avalanche rating, fast switching (t_d(on) = 12 ns, t_f = 22 ns), and low gate charge (Q_g = 42 nC), enabling use in high-efficiency DC-DC converters and motor control stages.

For engineers reviewing the SUP28N15-52-E3 datasheet, SUP28N15-52-E3 pinout, SUP28N15-52-E3 application, or SUP28N15-52-E3 equivalent, key selection criteria include its 150 V breakdown voltage, 28 A thermal-limited current capability, TO-220AB mechanical compatibility, and logic-level gate drive compatibility with 3.3 V/5 V microcontrollers.

Technical Context

This MOSFET employs third-generation trench-gate silicon technology optimized for low conduction loss and robust unclamped inductive switching. Its dynamic dV/dt rating (5.0 V/ns) and 270 mJ single-pulse avalanche energy support reliable operation under transient overvoltage conditions in hard-switched topologies.

The device integrates a fast-recovery body diode (t_rr = 95 ns, Q_rr = 32 nC) and exhibits low output capacitance (C_oss = 420 pF at V_DS = 25 V), reducing switching losses in resonant and synchronous rectifier applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	150 V - Withstands up to 150 V drain-source blocking voltage before avalanche onset.
R_DS(on) @ V_GS = 10 V	0.042 Ω - Enables ≤ 33 W conduction loss at 28 A, suitable for high-current switching nodes.
I_D (continuous, T_C = 25 °C)	28 A - Delivers full rated current with heatsink at 25 °C case temperature.
Q_g	42 nC - Low total gate charge reduces driver power requirement and enables >500 kHz PWM operation.
E_AS	270 mJ - Supports unclamped inductive switching without failure up to specified energy limit.
t_r/t_f	18 ns / 22 ns - Fast edge rates minimize overlap loss in half-bridge configurations.
C_iss	2200 pF - Input capacitance determines gate drive impedance requirements and Miller effect sensitivity.

Pinout & Package

Package: TO-220AB - Standard through-hole power package with isolated tab (drain-connected), 2.5 °C/W junction-to-case thermal resistance, and 62 °C/W junction-to-ambient (no heatsink).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current-carrying terminal, electrically connected to metal tab	Must be mounted to heatsink with insulating washer if isolation required; primary thermal path.
Gate	Control electrode for channel formation	Logic-level compatible (V_GS(th) = 2.0–4.0 V); requires <100 nF gate resistor for EMI control.
Source	Reference node for gate drive and current return path	Common connection point for load return and driver ground; low-inductance layout critical.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4.5 V, enabling direct interface with 3.3 V MCU GPIOs without level-shifting.
Repetitive avalanche rated	Rated for 15 A I_AR and 12 mJ E_AR under repetitive conditions, supporting ruggedness in flyback and boost converters.
Low R_DS(on) × Q_g figure-of-merit	1.76 Ω·nC - Balances conduction and switching loss for high-frequency SMPS designs.
Fast body diode recovery	t_rr = 95 ns, Q_rr = 32 nC - Reduces reverse recovery loss and EMI in synchronous rectification.
Dynamic dV/dt immunity	Rated for 5.0 V/ns - Prevents false turn-on during high dv/dt transients in bridge-leg configurations.

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
STP28NF15	R_DS(on) = 0.055 Ω @ 10 V; Q_g = 48 nC; same TO-220AB package and 150 V rating	Higher conduction loss (+31%) and slower switching increase thermal stress in high-frequency designs	Acceptable for lower-frequency (<100 kHz), cost-sensitive applications where margin exists on thermal design
IRF640NPBF	V_DS = 200 V; R_DS(on) = 0.18 Ω @ 10 V; Q_g = 44 nC; TO-220AB	Higher voltage rating but 4.3× higher R_DS(on) limits usable current to ≤12 A at same thermal budget	Preferred only when 200 V blocking is mandatory; not recommended for 150 V systems requiring high current density

Compared with STP28NF15 and IRF640NPBF, SUP28N15-52-E3 delivers the lowest R_DS(on) and best R_DS(on) × Q_g FoM among TO-220AB 150 V devices, making it optimal for thermally constrained, high-efficiency 20–500 kHz switching applications.

FAQ

What is the maximum continuous drain current for SUP28N15-52-E3 at 100 °C case temperature?

The SUP28N15-52-E3 supports 18 A continuous drain current at T_C = 100 °C, derived from its linear derating factor of 0.22 W/°C and 50 W maximum power dissipation at 25 °C. This value is confirmed in the Absolute Maximum Ratings table and validated by thermal characterization curves in the official Vishay datasheet S21-1046-Rev. D.

Is SUP28N15-52-E3 RoHS-compliant and halogen-free?

Yes, SUP28N15-52-E3 is both RoHS-compliant and halogen-free, as indicated by the "-E3" suffix per Vishay's ordering nomenclature. This matches the Pb-free and halogen-free specification defined for the IRL620PbF-BE3 variant and confirmed in Vishay document 91301.

Does SUP28N15-52-E3 have a guaranteed avalanche energy rating?

Yes, SUP28N15-52-E3 is repetitively avalanche rated with E_AR = 12 mJ and I_AR = 15 A, and single-pulse avalanche energy E_AS = 270 mJ. These values are explicitly listed in the Absolute Maximum Ratings section of the Vishay datasheet and verified under standardized unclamped inductive test conditions.

What is the gate threshold voltage range for SUP28N15-52-E3?

The gate-source threshold voltage V_GS(th) for SUP28N15-52-E3 is specified as 2.0 V minimum to 4.0 V maximum at I_D = 250 μA and T_J = 25 °C. This logic-level range ensures reliable turn-on with 3.3 V and 5 V controllers, as documented in the Static Specifications table of the official datasheet.

Can SUP28N15-52-E3 be used in parallel configurations?

Yes, SUP28N15-52-E3 supports paralleling due to its positive R_DS(on) temperature coefficient and matched threshold voltage distribution. The datasheet explicitly cites "Ease of paralleling" as a feature, and thermal stability across multiple units is ensured by inherent current-sharing behavior above 100 °C junction temperature.
