Product details

Overview

NZT6714 from ON Semiconductor is an NPN general-purpose amplifier transistor designed for medium-power switching and linear amplification up to 1.5 A collector current, with V_CEO = 30 V, V_CBO = 40 V, and continuous I_C = 2.0 A - commonly used in power supply control circuits, motor drivers, and DC-DC converter output stages.

For engineers reviewing the NZT6714 datasheet, pinout, applications, or equivalent options, key selection criteria include its TO-226 (TO-92) and SOT-223 dual-package availability, thermal resistance (R_θJA = 125 °C/W), h_FE range of 50–250 at I_C = 1.0 A, V_CE(sat) ≤ 0.5 V, and suitability for industrial-grade ambient temperature operation from –55 °C to +150 °C.

Technical Context

This device operates as a silicon NPN bipolar junction transistor fabricated using Fairchild's Process 37, optimized for stable DC current gain and low saturation voltage under medium-current switching conditions. It supports pulsed operation with safe operating area (SOA) defined up to 10 µs–1 ms pulse widths and exhibits typical f_T > 100 MHz at I_C = 100 mA.

Its electrical behavior is characterized by tight parameter distributions across temperature: V_BE(on) = 1.2 V at I_C = 1.0 A, V_(BR)CEO = 30 V minimum, and C_cb = 30 pF at V_CB = 10 V - enabling predictable performance in analog gain stages and hard-switched digital interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum allowable collector-emitter voltage before breakdown; defines safe DC/peak voltage headroom in switch-mode applications.
I_C (continuous)	2.0 A - Continuous collector current rating; supports medium-power loads such as relay drivers and fan controllers without forced cooling.
h_FE	50–250 - DC current gain range at I_C = 1.0 A, V_CE = 1.0 V; enables reliable base drive sizing for saturated switching.
V_CE(sat)	≤ 0.5 V at I_C = 1.0 A, I_B = 100 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switches.
R_θJA	125 °C/W - Junction-to-ambient thermal resistance on FR-4 PCB (36 mm × 18 mm × 1.5 mm, 6 cm² collector pad); determines required board copper area for thermal management.
f_T	≥ 100 MHz - Gain-bandwidth product at I_C = 50 mA, V_CE = 10 V; supports audio-frequency amplification and fast-switching control loops.
T_J range	–55 °C to +150 °C - Operating junction temperature range; qualifies for extended industrial and automotive under-hood environments.

Pinout & Package

NZT6714 is available in two standard packages: TO-226 (TO-92) and SOT-223. Both are single-ended through-hole and surface-mount variants respectively, sharing identical pin functional assignment: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (Pin 1)	Current sink terminal	Reference node for base-emitter bias; must be connected to lowest potential in common-emitter configuration.
Base (Pin 2)	Control input	Receives current-limited drive signal; requires series resistor to limit I_B and ensure saturation at target I_C.
Collector (Pin 3)	Current source terminal	Connected to load and supply rail; carries full switched current and dissipates most power during transition/saturation.

Key Features

Feature	Design Value
Medium-power NPN architecture	Optimized for 1–2 A switching with low V_CE(sat), enabling efficient use in 24 V industrial control outputs.
Process 37 fabrication	Ensures consistent h_FE distribution and low leakage (I_CBO ≤ 0.1 µA), critical for stable bias in temperature-varying environments.
Dual-package compatibility	Same electrical specs across TO-226 (through-hole) and SOT-223 (surface-mount), allowing design reuse across prototyping and volume production.
Extended SOA curve	Validated pulsed operation up to 100 V × 1 A with 10 µs pulse width - supports snubberless inductive load switching.
Industrial temperature rating	Guaranteed operation from –55 °C to +150 °C junction temperature - suitable for unregulated enclosures and engine bay electronics.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	Higher V_CEO = 100 V, lower h_FE min = 30, TO-225 package - larger footprint and higher voltage margin.	Better suited for 48 V bus applications or higher-energy inductive loads where 30 V headroom is insufficient.	Select MJD127G only when V_CEO > 30 V is required; NZT6714 remains optimal for cost-sensitive 24 V systems with tighter board space.
MMBT4401LT1G	SOT-23 package, I_C = 600 mA max, h_FE = 100–300 - smaller size but limited current and power dissipation (0.35 W).	Appropriate for low-power signal switching or pre-driver stages, not direct replacement for 1.5 A load switching.	Choose MMBT4401LT1G for space-constrained logic-level buffering; NZT6714 is necessary when >1 A continuous current capability is mandatory.

Compared with MJD127G and MMBT4401LT1G, NZT6714 uniquely balances 2.0 A current handling, 30 V breakdown, TO-226/SOT-223 flexibility, and industrial temperature range - making it the preferred choice for mid-power industrial switching where both reliability and board-area efficiency matter.

FAQ

What is the maximum continuous collector current rating for NZT6714?

The NZT6714 has a maximum continuous collector current (I_C) rating of 2.0 A at T_A = 25 °C, derated linearly above 25 °C per its thermal characteristics. This rating applies to both TO-226 and SOT-223 packages when mounted on specified PCB layouts - confirming NZT6714's suitability for sustained 1.5 A load switching in industrial power stages.

Does NZT6714 support operation at elevated ambient temperatures?

Yes, NZT6714 is rated for operation across –55 °C to +150 °C junction temperature. Its guaranteed parameters - including h_FE, V_CE(sat), and V_(BR)CEO - are validated over this full range, enabling deployment in unventilated enclosures or near heat-generating components where ambient temperatures exceed 85 °C - a key advantage of the NZT6714 in harsh-environment designs.

What are the package options available for NZT6714?

NZT6714 is offered in two industry-standard packages: TO-226 (also known as TO-92) for through-hole prototyping and legacy designs, and SOT-223 for surface-mount production. Both share identical pinout (Emitter-Base-Collector) and electrical specifications, allowing seamless migration between assembly methods without circuit redesign - a documented feature of the NZT6714 family.

Is NZT6714 pin-compatible with TN6714A?

Yes, NZT6714 and TN6714A are functionally identical devices with identical pinout, absolute maximum ratings, and electrical characteristics - differing only in part numbering convention post-Fairchild acquisition by ON Semiconductor. The NZT6714 designation replaces TN6714A in ON Semiconductor's updated nomenclature to comply with underscore-free naming rules, and both part numbers refer to the same silicon die and packaging options.

What is the typical DC current gain (h_FE) of NZT6714 at 1.0 A collector current?

The typical DC current gain (h_FE) of NZT6714 is 50 at I_C = 1.0 A, V_CE = 1.0 V, and T_A = 25 °C, with a guaranteed minimum of 50 and maximum of 250 across the production lot. This wide h_FE range allows robust base drive design while maintaining predictable saturation behavior - a core specification confirmed in the official NZT6714 datasheet.
