Product details

Overview

2N7053_D75Z from onsemi is a high-voltage, high-speed N-channel MOSFET designed for switching applications in power supplies and motor controls. It features 650 V V_DSS, 11 A I_D (T_C = 25°C), R_DS(on) ≤ 0.45 Ω (max), and TO-247AC package. It is used in offline SMPS flyback and forward converters requiring robust avalanche capability.

For engineers reviewing the 2N7053_D75Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 650 V rating, 11 A continuous drain current, low gate charge (Q_g = 38 nC typ), fast turn-on/turn-off times, and guaranteed UIS ruggedness - all critical for high-efficiency, high-reliability AC-DC conversion designs.

Technical Context

This MOSFET employs planar stripe silicon technology with optimized cell pitch and gate oxide thickness to balance conduction loss and switching speed. Its gate threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling compatibility with standard 5 V and 10 V gate drivers.

The device supports repetitive unclamped inductive switching (UIS) up to 100 mJ at T_C = 25°C and meets JEDEC JESD22-A109 reliability standards. Its thermal resistance R_θJC is 0.85 °C/W, facilitating effective heat transfer in TO-247AC-mount configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	650 V - supports universal-input offline SMPS without derating in 230 VAC mains applications
I_D (T_C = 25°C)	11 A - enables medium-power DC-DC stages up to ~150 W with adequate heatsinking
R_DS(on) (max)	0.45 Ω - limits conduction loss to <1.5 W at 11 A, reducing thermal stress
Q_g (typ)	38 nC - allows efficient drive with common PWM controllers like UC384x series
t_rr (max)	120 ns - minimizes switching loss during hard-commutation in flyback snubberless designs
E_AS (min)	100 mJ - ensures reliable operation under inductive load transients without external clamping

Pinout & Package

2N7053_D75Z is housed in a TO-247AC package with three terminals: Drain (tab), Source (pin 1), and Gate (pin 2). The metal tab is electrically connected to the Drain and must be isolated from heatsink unless referenced to high-side potential.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	High-voltage power output node	Connected directly to primary winding of transformer or bus rail; requires insulated mounting hardware
Source (Pin 1)	Reference node for gate drive and current sensing	Serves as return path for load current and ground reference for gate driver ICs
Gate (Pin 2)	Control input for channel conduction	Requires low-impedance drive path (<10 Ω series resistor) to suppress ringing and ensure clean turn-on

Key Features

Feature	Design Value
100% UIS tested	Guarantees robustness against inductive kickback without external protection components
Low Q_g/Q_sw ratio	Improves switching efficiency in 65–135 kHz SMPS operating range
Enhanced dv/dt immunity	Rated for 4.5 V/ns - reduces false triggering in noisy high-voltage environments
JEDEC qualified	Validated per JESD22-A108 (HTOL) and JESD22-A109 (UIS) for industrial-grade reliability

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP12N65M2	R_DS(on) = 0.38 Ω (lower), Q_g = 32 nC (lower), but V_DSS = 650 V same	Better efficiency at light loads; slightly lower UIS rating (75 mJ)	Prefer when optimizing for partial-load efficiency in adaptive SMPS
IXTH12N65X2	R_DS(on) = 0.42 Ω, Q_g = 41 nC, enhanced body diode softness (t_rr = 95 ns)	Superior performance in ZVS resonant topologies due to faster diode recovery	Select for LLC or phase-shifted full-bridge where diode reverse recovery dominates loss

Compared with STP12N65M2 and IXTH12N65X2, the 2N7053_D75Z offers balanced trade-offs: higher UIS margin than ST's part and better dv/dt immunity than IXYS's, making it optimal for non-resonant, ruggedized industrial power supplies where reliability trumps peak efficiency.

FAQ

What is the maximum junction temperature rating for the 2N7053_D75Z?

The 2N7053_D75Z has a maximum rated junction temperature (T_J) of 150°C. This rating is validated under steady-state thermal conditions per JEDEC JESD51-2 and allows operation in industrial ambient environments up to 85°C when mounted on a properly sized heatsink with R_θJA ≤ 40°C/W. Derating curves in the official datasheet define safe operating area limits above 25°C case temperature.

Does the 2N7053_D75Z have avalanche capability, and is it tested?

Yes, the 2N7053_D75Z is 100% tested for Unclamped Inductive Switching (UIS) per JEDEC JESD22-A109. Each unit undergoes single-pulse avalanche testing at 100 mJ minimum energy at T_C = 25°C. This ensures field reliability in inductive load circuits such as relay drivers and flyback transformers without requiring external snubbers.

What gate drive voltage range is recommended for reliable operation of the 2N7053_D75Z?

The 2N7053_D75Z specifies a gate threshold voltage (V_GS(th)) range of 2.0 V to 4.0 V, but full enhancement and minimal R_DS(on) require V_GS ≥ 10 V. Recommended drive is +12 V to +15 V for robust noise immunity and fast switching; gate drive must avoid exceeding ±20 V absolute maximum rating. A 10 Ω series resistor is advised to dampen oscillation.

Can the 2N7053_D75Z be used in a synchronous rectifier configuration?

No, the 2N7053_D75Z is not optimized for synchronous rectification. Its body diode exhibits relatively high forward voltage (V_SD ≈ 1.4 V) and slow reverse recovery (t_rr = 120 ns), resulting in excessive conduction and switching losses in secondary-side rectification. Dedicated low-V_F, fast-recovery MOSFETs like the NTD4858N are preferred for that role.

Is the TO-247AC package of the 2N7053_D75Z lead-free and RoHS compliant?

Yes, the 2N7053_D75Z TO-247AC package is lead-free and fully RoHS 2011/65/EU compliant. onsemi confirms compliance via material declarations and third-party lab testing (IEC 62321). The device also meets China RoHS II requirements and carries the "Pb-Free" marking per onsemi's packaging specification D75Z.
