Product details

Overview

2N3416_D26Z from Fairchild Semiconductor is an NPN general-purpose bipolar junction transistor (BJT) designed for amplification and switching applications with continuous collector current up to 500 mA and V_CEO = 50 V. It features h_FE = 75–225 at I_C = 2.0 mA, V_CE = 4.5 V, and is housed in a TO-92 package with emitter-first tape-and-reel configuration (EOL code D26Z). It is commonly used in low-voltage DC-DC converter drivers and signal buffering stages.

For engineers reviewing the 2N3416_D26Z datasheet, pinout, applications, or equivalent options, key selection criteria include verified h_FE range, V_CEO/V_CBO breakdown ratings, thermal resistance (R_θJA = 200 °C/W), saturation voltage (V_CE(sat) ≤ 0.3 V @ I_C = 50 mA), and TO-92 mechanical compatibility for through-hole prototyping and production.

Technical Context

The 2N3416_D26Z operates as a silicon NPN BJT fabricated on Fairchild's Process 10, optimized for linear amplification and saturated switching. Its DC current gain (h_FE) is specified between 75 and 225 under standardized conditions (V_CE = 4.5 V, I_C = 2.0 mA), and small-signal current gain (h_fe) matches this range at 1 kHz.

It supports continuous operation from −55°C to +150°C junction temperature, with thermal limits defined by R_θJC = 83.3 °C/W and R_θJA = 200 °C/W. Absolute maximum ratings include V_CEO = V_VCBO = 50 V and I_C = 500 mA, making it suitable for medium-current, low-to-mid voltage analog and digital interface circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum allowable collector-emitter voltage before breakdown; defines safe operating voltage headroom in switching designs.
I_C (continuous)	500 mA - Sustained collector current capability; supports relay drivers and medium-power amplifier stages.
h_FE	75–225 - DC current gain range at V_CE = 4.5 V, I_C = 2.0 mA; determines base drive requirements for saturation.
V_CE(sat)	≤ 0.3 V @ I_C = 50 mA, I_B = 3.0 mA - Low saturation voltage minimizes power loss and heating in switch-mode operation.
R_θJA	200 °C/W - Junction-to-ambient thermal resistance; informs heatsinking needs for >100 mW dissipation in still-air environments.
T_J range	−55°C to +150°C - Full operational junction temperature span; enables use in industrial and automotive under-hood environments.

Pinout & Package

2N3416_D26Z is supplied in a standard TO-92 plastic package with straight leads and no lead clip. The device uses emitter-first orientation in tape-and-reel packaging (EOL code D26Z), where the first wire off the reel is the emitter terminal.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (E)	Current exit path for majority carriers	Reference node for biasing; connected to ground or low-impedance return in common-emitter configurations.
Base (B)	Control electrode for carrier injection	Receives low-current drive to modulate collector current; requires current-limiting resistor in most applications.
Collector (C)	Current entry path for majority carriers	Connected to load or supply rail; carries amplified/saturated output current up to 500 mA.

Key Features

Feature	Design Value
General-purpose NPN architecture	Enables dual-use in both linear amplification (e.g., preamp stages) and digital switching (e.g., logic-level translators).
Verified h_FE spread (75–225)	Supports robust design margining across production lots without requiring individual gain binning.
V_CEO = V_VCBO = 50 V	Allows direct replacement of legacy 2N2222A-class devices in 24 V and 36 V industrial control systems.
TO-92 mechanical standardization	Ensures compatibility with automated insertion equipment, wave soldering profiles, and hand-soldering fixtures.

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
PN2222A	Higher h_FE min (100 vs. 75), identical V_CEO/I_C, same TO-92 package	Slightly better gain consistency in low-noise preamp designs; otherwise functionally interchangeable	Select PN2222A when tighter h_FE distribution is required; 2N3416_D26Z remains optimal for cost-sensitive volume production.
BC547B	Lower V_CEO (45 V), higher h_FE (200–450), same TO-92 footprint but different pinout (E-C-B vs. E-B-C)	Not pin-compatible; requires PCB layout revision; preferred in European industrial designs due to Pro Electron compliance	Choose BC547B only if redesign is acceptable and higher gain at lower voltage is prioritized; 2N3416_D26Z avoids layout change and supports 50 V systems.

Compared with PN2222A and BC547B, the 2N3416_D26Z offers balanced performance for mid-range gain and voltage requirements in legacy-compatible TO-92 layouts, with documented thermal behavior (R_θJA = 200 °C/W) and process-controlled saturation characteristics ideal for cost-driven industrial control modules.

FAQ

What is the pin configuration of the 2N3416_D26Z?

The 2N3416_D26Z uses the standard TO-92 package with Emitter-Base-Collector (E-B-C) pinout when viewed with the flat side facing forward and leads pointing downward. Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector. This configuration is confirmed in Fairchild's 2N3416/2N3417 datasheet Rev B and applies specifically to the D26Z tape-and-reel variant of the 2N3416_D26Z.

Does the 2N3416_D26Z support pulsed operation beyond its continuous ratings?

Yes - the 2N3416_D26Z supports pulsed operation per Fairchild's note: "Pulse Test: Pulse Width ≤ 300 µs, Duty Cycle ≤ 2.0%." Under these conditions, peak collector current may exceed 500 mA, but users must consult Fairchild's application guidance for derating curves and thermal transient analysis to avoid junction overheating in the 2N3416_D26Z.

Is the 2N3416_D26Z RoHS compliant?

The 2N3416_D26Z was manufactured prior to full RoHS enforcement and is not certified RoHS compliant. It contains lead in the die attach and lead frame plating. For new designs requiring RoHS compliance, consider modern alternatives such as the NSS20201MR6T1G or MMBT2222ALT1G, but verify pinout and gain matching before substitution in the 2N3416_D26Z footprint.

What is the maximum power dissipation for the 2N3416_D26Z at 70°C ambient?

At 70°C ambient, the 2N3416_D26Z has a derated power dissipation of 412.5 mW. This is calculated from its 625 mW rating at 25°C and 5.0 mW/°C derating factor: 625 mW − (5.0 mW/°C × (70 − 25)°C) = 412.5 mW. Exceeding this limit risks exceeding the 150°C maximum junction temperature in the 2N3416_D26Z.

Can the 2N3416_D26Z replace the 2N2222 in existing designs?

Yes - the 2N3416_D26Z is a functional and pin-compatible replacement for the 2N2222 in most applications. Both share TO-92 packaging, E-B-C pinout, and similar V_CEO (50 V) and I_C (500 mA) ratings. However, the 2N3416_D26Z has a lower minimum h_FE (75 vs. 100 for 2N2222), so verify gain margin in high-fidelity amplifier stages before substituting the 2N3416_D26Z.
