Product details

Overview

2N4410_D75Z from Fairchild Semiconductor is an NPN general-purpose amplifier transistor in TO-92 package, rated for V_CEO = 80 V, I_C = 200 mA continuous, and h_FE = 60–400 at I_C = 1.0–10 mA. It serves as a low-power linear amplifier or switching element in signal conditioning, interface logic, and small-signal load control circuits.

For engineers reviewing the 2N4410_D75Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 80 V V_CEO, 200 mA I_C rating, TO-92 mechanical compatibility, thermal resistance of 200 °C/W (R_θJA), and verified h_FE range across operating current.

Technical Context

The 2N4410_D75Z operates as a silicon NPN bipolar junction transistor fabricated on Fairchild's Process 16. Its design supports both analog amplification (with h_fe ≥ 2.0 at 30 MHz) and digital switching (V_CE(sat) ≤ 0.2 V at I_C = 1.0 mA, I_B = 0.1 mA).

It features low output capacitance (C_ob = 12 pF at V_CB = 10 V) and input capacitance (C_ib = 50 pF at V_EB = 0.5 V), enabling stable performance in audio-frequency and low-MHz switching applications without unintended resonance or bandwidth limitation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions; defines upper rail limit in amplifier or switch designs.
I_C (continuous)	200 mA - Absolute maximum DC collector current; usable up to 50 mA per original application intent without thermal derating.
h_FE	60–400 - DC current gain range at V_CE = 1.0 V; enables predictable biasing for Class-A amplifiers or saturated switches.
R_θJA	200 °C/W - Junction-to-ambient thermal resistance in free-air; requires heatsinking or layout derating above ~125 mW dissipation.
C_ob	12 pF - Output capacitance at V_CB = 10 V; limits high-frequency gain roll-off and affects stability in RF-adjacent stages.
V_BE(sat)	0.8 V - Base-emitter saturation voltage at I_C = 1.0 mA, I_B = 0.1 mA; determines minimum drive voltage needed for full turn-on.

Pinout & Package

2N4410_D75Z is supplied in TO-92 plastic package with straight leads and no lead clip. Per Fairchild's D75Z ammo packaging specification, the flat side faces upward and the first wire off the package is the collector.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (E)	Current sink terminal	Reference node for bias networks; connects to ground or low-impedance return path in common-emitter configurations.
Base (B)	Control input	Receives current-limited drive to regulate collector current; requires series resistor to limit I_B and prevent thermal runaway.
Collector (C)	Current source terminal	Delivers amplified or switched output current; connects to load and supply rail in active or saturated operation.

Key Features

Feature	Design Value
High V_CEO rating	80 V enables use in 24–48 V industrial control rails without additional protection circuitry.
Wide h_FE range	60–400 allows robust bias design across process variation while maintaining gain stability in linear stages.
Low V_CE(sat)	≤0.2 V at I_C/I_B = 10 ensures minimal conduction loss and heat generation in switching applications.
TO-92 mechanical standardization	Compatible with legacy through-hole PCB footprints and automated insertion equipment used for PN2222A/2N3904 families.

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	V_CEO = 40 V (vs. 80 V); h_FE min = 100 at I_C = 10 mA; same TO-92 package.	Not suitable for >40 V collector rails; preferred where higher minimum h_FE improves bias stability at 10 mA.	Select PN2222A when supply voltage ≤ 30 V and tighter h_FE tolerance is needed; avoid if V_CC > 40 V.
2N3904	I_C = 200 mA (same); V_CEO = 40 V; h_FE = 100–300; lower C_ob = 8 pF.	Better HF response but insufficient for 80 V applications; widely available in tape-and-reel.	Choose 2N3904 for high-frequency signal switching below 40 V; retain 2N4410_D75Z for 48–80 V industrial interfaces.

Compared with PN2222A and 2N3904, the 2N4410_D75Z provides unique 80 V V_CEO headroom while retaining TO-92 compatibility-critical for upgrading legacy 24/48 V control boards without footprint changes or voltage derating.

FAQ

What is the pinout configuration of the 2N4410_D75Z?

The 2N4410_D75Z uses standard TO-92 pinout: viewed with flat side facing up and leads downward, left-to-right pins are Emitter (E), Base (B), Collector (C). This matches Fairchild's D75Z ammo packaging specification where the flat side is up and first wire off is collector.

Does the 2N4410_D75Z support switching applications?

Yes, the 2N4410_D75Z supports switching applications with V_CE(sat) ≤ 0.2 V at I_C = 1.0 mA and I_B = 0.1 mA, and a maximum continuous collector current of 200 mA. Its 80 V V_CEO rating allows reliable operation in 24–48 V DC control circuits without snubbing.

What is the maximum operating temperature for the 2N4410_D75Z?

The 2N4410_D75Z has a specified operating junction temperature range of –55 °C to +150 °C. At ambient temperatures above 25 °C, power dissipation must be linearly derated at 5.0 mW/°C, based on its 625 mW total device dissipation rating.

How does the 2N4410_D75Z compare to the 2N5551?

The 2N4410_D75Z shares process and characterization methodology with the 2N5551 per Fairchild documentation, but differs in absolute ratings: 2N5551 offers V_CEO = 160 V and I_C = 600 mA, while 2N4410_D75Z is optimized for lower-current, cost-sensitive applications with tighter h_FE spread and TO-92 packaging.

Is the 2N4410_D75Z RoHS compliant?

Yes, the 2N4410_D75Z manufactured under Fairchild's post-2006 production standards meets RoHS Directive 2011/65/EU requirements, with lead-free finish and halogen-free molding compound confirmed in Fairchild's material declarations for TO-92 packaged transistors bearing D75Z reel/ammo codes.
