Product details

Overview

2N4410_D27Z 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 and interface circuits.

For engineers reviewing the 2N4410_D27Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 80 V V_CEO, 12 pF Cob output capacitance, TO-92 mechanical compatibility, thermal resistance of 200 °C/W (R_θJA), and suitability for 50 mA collector-current switching tasks.

Technical Context

The 2N4410_D27Z implements a silicon planar NPN bipolar junction transistor structure optimized for general-purpose amplification and switching up to 50 mA DC load current. Its design targets stable h_FE across I_C = 1–10 mA and low V_CE(sat) = 0.2 V at I_C/I_B = 10/1.

It operates over –55°C to +150°C junction temperature range with 625 mW total power dissipation at 25°C, derating linearly at 5.0 mW/°C above ambient. The device uses Process 16 and shares electrical characteristics with the 2N5551 family but features distinct voltage and gain boundaries.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions
I_C (cont.)	200 mA - Continuous collector current rating defining maximum steady-state load drive capability
h_FE	60–400 - DC current gain range enabling predictable base drive sizing for amplification or saturation
V_CE(sat)	0.2 V - Low saturation voltage ensures minimal power loss when used as a switch
C_ob	12 pF - Output capacitance limiting high-frequency response in amplifier configurations
R_θJA	200 °C/W - Junction-to-ambient thermal resistance indicating required PCB copper area for thermal management
P_D	625 mW - Total power dissipation limit at 25°C ambient, critical for thermal design margining

Pinout & Package

2N4410_D27Z is housed in a standard TO-92 plastic package with straight leads and no lead clip. Pin orientation follows Emitter–Base–Collector (EBC) sequence when viewed with flat side facing outward and leads pointing downward.

Pin/Terminal	Circuit Role	Design Meaning
Lead 1 (left)	Emitter	Current sink terminal; connects to ground or low-side return path in common-emitter configurations
Lead 2 (center)	Base	Control input requiring ~0.8 V forward bias and precise current limiting for reliable turn-on
Lead 3 (right)	Collector	Current source terminal; interfaces with load or pull-up resistor in switching or amplification topologies

Key Features

Feature	Design Value

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
2N2222A	V_CEO = 40 V (lower), h_FE = 100–300, R_θJA = 200 °C/W same	Limited to ≤24 V supply rails; less margin for transient overvoltage	Select when lower cost and tighter h_FE tolerance are prioritized over voltage headroom
PN2222A	Same V_CEO = 40 V, but TO-92 variant with tighter h_FE binning (100–300); identical pinout	Not suitable for 48 V systems; better consistency in batch-sensitive analog designs	Prefer for volume production where h_FE matching across units reduces calibration overhead

Compared with 2N4410_D27Z, both 2N2222A and PN2222A offer lower V_CEO (40 V vs. 80 V), reducing system-level surge protection requirements but restricting use in higher-voltage industrial interfaces; all three share TO-92 packaging and EBC pinout, enabling drop-in substitution only where voltage ratings are verified.

FAQ

What is the pin configuration of the 2N4410_D27Z?

The 2N4410_D27Z uses a standard TO-92 package with Emitter–Base–Collector (EBC) pinout when viewed with the flat side facing outward and leads pointing down. Lead 1 (left) is Emitter, Lead 2 (center) is Base, and Lead 3 (right) is Collector. This matches JEDEC TO-92 mechanical specification and is confirmed in Fairchild's tape-and-reel documentation for D27Z ordering code.

Does the 2N4410_D27Z support switching applications up to 50 mA?

Yes, the 2N4410_D27Z is explicitly characterized for switching applications requiring collector currents up to 50 mA, as stated in its official Fairchild datasheet. Its V_CE(sat) = 0.2 V at I_C = 1.0 mA and I_B = 0.1 mA, and I_C (continuous) = 200 mA confirm robust DC switching capability well beyond 50 mA, provided thermal limits are observed.

What is the maximum operating temperature for the 2N4410_D27Z?

The 2N4410_D27Z has a specified operating junction temperature range of –55°C to +150°C. This allows deployment in harsh environments such as industrial control cabinets or automotive under-dash locations. Ambient temperature limits depend on power dissipation and PCB thermal design, with R_θJA = 200 °C/W defining the thermal gradient from junction to ambient air.

How does the 2N4410_D27Z differ from the 2N5551?

The 2N4410_D27Z and 2N5551 share Process 16 fabrication but differ in key parameters: the 2N4410_D27Z has V_CEO = 80 V and h_FE = 60–400, while the 2N5551 specifies V_CEO = 160 V and h_FE = 80–250. The 2N4410_D27Z is optimized for general-purpose use with broader gain spread; the 2N5551 targets higher-voltage, higher-speed applications.

Is the 2N4410_D27Z RoHS compliant?

The 2N4410_D27Z was manufactured prior to full RoHS enforcement and is not certified RoHS compliant. Fairchild's documentation indicates it contains leaded solder in the die attach and lead frame plating. For new designs requiring RoHS compliance, consider modern alternatives such as the MMBT2222ALT1G or NSS2222LT1G, which maintain functional equivalence with Pb-free construction.
