Product details

Overview

NZT560 from onsemi is an NPN low-saturation transistor designed for high-current switching in power management circuits, featuring 60 V V_CEO, 3 A continuous collector current, and 450 mV V_CE(sat) at I_C = 3 A / I_B = 300 mA - used in DC-DC converter output stages and motor driver H-bridge legs.

For engineers reviewing the NZT560 datasheet, pinout, applications, or equivalent options, key selection criteria include saturation voltage at high current, thermal resistance (125 °C/W), DC current gain range (100–300 at 100 mA), junction temperature rating (−55 to +150 °C), and SOT-223 package compatibility with board-level thermal relief.

Technical Context

This device operates as a medium-power NPN bipolar junction transistor optimized for low V_CE(sat) under high-current conduction, with verified h_FE of 100–300 at I_C = 100 mA and 25–80 at I_C = 3 A. Its 80 V V_CBO and 5 V V_EBO support robust base-emitter and collector-base blocking in unidirectional switch configurations.

Thermal performance is defined for FR-4 PCBs (76 mm × 114 mm × 1.57 mm) with R_JA = 125 °C/W and derating of 8 mW/°C above 25 °C. The SOT-223 package integrates a thermally enhanced tab connected internally to the collector, enabling direct heatsinking without isolation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - maximum safe collector-emitter voltage before breakdown in common-emitter configuration
I_C (continuous)	3 A - sustained collector current capability with thermal management per specified PCB layout
V_CE(sat)	450 mV @ I_C = 3 A, I_B = 300 mA - low conduction loss enabling >95% efficiency in 12 V load switches
h_FE	100–300 @ I_C = 100 mA - sufficient DC gain for direct TTL/CMOS drive without external amplification
R_JA	125 °C/W - thermal resistance from junction to ambient on standard 3×4.5 inch FR-4 board
f_T	75 MHz - usable for PWM frequencies up to ~5–10 MHz with acceptable gain roll-off
T_J range	−55 to +150 °C - qualified for industrial and under-hood automotive environments

Pinout & Package

SOT-223 (Case 318H) package with exposed collector tab for thermal conduction; 4-pin configuration where pins 2 and 4 are internally tied to collector, pin 1 is base, and pin 3 is emitter.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Control input requiring ~300 mA drive current to saturate at 3 A collector load
Pins 2 & 4	Collector	Internally shorted; primary power path and thermal interface via exposed copper tab
Pin 3	Emitter	Reference node for load return; must be routed with low-inductance path in high-dI/dt applications

Key Features

Feature	Design Value
Low V_CE(sat)	450 mV max at full 3 A load - reduces power dissipation to ≤1.35 W versus >3 W for standard transistors
High h_FE at mid-current	250–550 for NZT560A variant - enables reduced base drive power and simpler gate driver design
Pb-free SOT-223 package	RoHS-compliant construction with thermal pad optimized for reflow soldering and mechanical reliability
Extended temperature operation	Rated from −55 °C to +150 °C - supports deployment in sealed enclosures without active cooling

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	Higher V_CEO (80 V), lower h_FE (20–120), higher V_CE(sat) (1.1 V @ 3 A)	Better suited for 48 V systems; less efficient at 12 V due to higher conduction loss	Select when higher voltage blocking is required and thermal budget allows >3 W dissipation
ZXTN25050DFH	Lower V_CE(sat) (200 mV @ 3 A), SOT-89 package, no collector tab	Superior efficiency but limited thermal capacity; unsuitable for sustained 3 A without external heatsink	Prefer for space-constrained designs with intermittent duty cycle and active cooling

Compared with MJD127G and ZXTN25050DFH, NZT560 offers balanced voltage rating, proven thermal performance in SOT-223, and predictable saturation behavior across temperature - making it optimal for cost-sensitive, thermally constrained 12–24 V industrial switching.

FAQ

What is the maximum continuous collector current rating for NZT560?

The NZT560 is rated for 3 A continuous collector current at T_A = 25 °C with proper PCB thermal management per the datasheet's FR-4 layout (76 mm × 114 mm). Derating applies above 25 °C at 8 mW/°C, and actual achievable current depends on ambient temperature, airflow, and copper area. NZT560 must not exceed its 150 °C maximum junction temperature under any operating condition.

Does NZT560 have a built-in thermal pad, and how should it be connected?

Yes, the NZT560 in SOT-223 (Case 318H) features an exposed collector tab that serves as both electrical connection and thermal interface. Pins 2 and 4 are internally tied to this tab, so the collector must be connected to a large copper pour or heatsink. Proper soldering of the tab is essential - insufficient thermal land area or voiding will cause junction overheating and premature failure of the NZT560.

How does NZT560 differ from NZT560A in terms of DC current gain?

The NZT560A exhibits higher DC current gain: h_FE = 250–550 at I_C = 500 mA, compared to NZT560's 100–300. This allows lower base drive current for the same collector load, reducing driver-stage power consumption. Both share identical absolute maximum ratings and thermal characteristics, so NZT560A can be substituted where higher gain improves system efficiency - but verify base drive capability remains within spec for the NZT560A.

Is NZT560 suitable for PWM motor control applications?

Yes, NZT560 is widely used in PWM-driven brushed DC motor control, especially in 12–24 V systems. Its 75 MHz f_T, fast turn-on/off times (typical t_on < 50 ns, t_off < 200 ns per typical curves), and low V_CE(sat) enable clean switching up to 20 kHz. For reliable operation, ensure base drive provides ≥300 mA peak current and use snubbers or freewheeling diodes to suppress inductive flyback voltage exceeding 60 V.

What is the lead-free status and marking convention for NZT560?

The NZT560 is Pb-free and RoHS-compliant, marked per the generic SOT-223 scheme: "AYW" followed by "560" (or "560A") - where "A" indicates assembly location, "Y" the year code, and "W" the work week. A microdot or "G" may appear as Pb-free indicator, though its presence is not guaranteed per onsemi's marking specification. The "/D" suffix in ordering code NZT560A/D denotes tape-and-reel packaging (4,000 units).
