Product details

Overview

PN2484_D75Z from Fairchild Semiconductor is an NPN general-purpose amplifier transistor optimized for low-noise, high-gain signal amplification at collector currents from 1 µA to 50 mA. It features V_CEO = 60 V, h_FE = 800 (at I_C = 10 mA), NF = 3.0 dB (at I_C = 10 µA), and is packaged in TO-92 with collector-first orientation per D75Z tape-and-reel specification.

For engineers reviewing the PN2484_D75Z datasheet, pinout, applications, or equivalent options, key selection criteria include noise figure at microamp bias, DC current gain linearity across 1 µA–10 mA, thermal resistance (R_θJA = 357 °C/W on FR-4), and TO-92 mechanical compatibility with D75Z reel packaging.

Technical Context

This device belongs to Fairchild's Process 07 bipolar transistor family, sharing core electrical characteristics with the 2N5088 but optimized for general-purpose amplification rather than ultra-low-noise RF use. Its h_FE spans 30 to 800 across I_C = 1 µA–10 mA, supporting wide dynamic range biasing.

The PN2484_D75Z operates within a junction temperature range of −55°C to +150°C and exhibits V_CE(sat) = 0.35 V (I_C = 1 mA, I_B = 0.1 mA) and V_BE(on) = 0.5–0.7 V (I_C = 100 µA), enabling stable Class-A small-signal stage design in discrete analog circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum safe collector-emitter voltage before breakdown; defines headroom for single-supply amplifier stages.
h_FE	800 at I_C = 10 mA - High DC current gain enables low-base-drive designs in preamplifier and sensor interface circuits.
Noise Figure	3.0 dB at I_C = 10 µA - Low intrinsic noise supports precision microamp-biased amplification in instrumentation front-ends.
P_D	350 mW - Power dissipation limit at 25°C; derates 2.8 mW/°C above ambient, constraining continuous output swing in linear operation.
R_θJA	357 °C/W - Thermal resistance on FR-4 PCB; dictates maximum allowable power under ambient conditions without heatsinking.
C_obo	6.0 pF at V_CB = 5 V - Output capacitance affects high-frequency gain roll-off and stability in tuned amplifier designs.

Pinout & Package

PN2484_D75Z is supplied in TO-92 package with collector-first orientation per D75Z tape-and-reel specification: flat side up, adhesive tape on top, first wire off is collector. Pin configuration is standardized as C–B–E (top view, leads down).

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Output current sink node	Primary current path for amplified signal; connects to load resistor or next stage input; highest voltage rating (60 V).
Base (B)	Control electrode	Receives input bias current; requires precise current sourcing to maintain h_FE-dependent operating point.
Emitter (E)	Current return path	Common reference for input and output; typically tied to ground or emitter degeneration resistor for stability.

Key Features

Feature	Design Value
Low-noise amplification	3.0 dB noise figure at 1 kHz enables high-SNR signal conditioning in sensor interfaces and audio preamps.
Wide h_FE range	30–800 across 1 µA–10 mA collector current supports flexible biasing for varying gain and linearity requirements.
High V_CEO/V_CBO	60 V rating allows operation in 24 V and 48 V industrial supply rails without derating.
TO-92 D75Z reel compliance	Standardized tape-and-reel packaging (2000 units/reel, P-style) ensures automated SMT placement compatibility.

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
MMBT2484	Identical die and electrical specs; differs only in SOT-23 packaging and marking (1U), no TO-92 mechanical compatibility.	Preferred for space-constrained PCBs where TO-92 footprint is prohibitive; not suitable for through-hole assembly or legacy socketed designs.	Select MMBT2484 when board real estate is limited and reflow-compatible SMT placement is available.
2N5088	Same Process 07 origin; higher h_FE min (40 vs. 30) at I_C = 1 µA, otherwise identical V_CEO, NF, and thermal specs.	Used in ultra-low-current amplifier designs requiring guaranteed gain >40 at sub-µA bias; slightly tighter h_FE distribution.	Choose 2N5088 when minimum h_FE at microamp bias is critical and TO-92 packaging is required.

Compared with MMBT2484 and 2N5088, PN2484_D75Z offers identical core amplification performance in TO-92 form with D75Z reel packaging-ideal for automated through-hole insertion and legacy-compatible designs where SOT-23 or tighter h_FE tolerance are not required.

FAQ

What is the pin configuration of PN2484_D75Z?

PN2484_D75Z uses standard TO-92 pinout with collector-first orientation per D75Z specification: flat side up, adhesive tape on top, and leads arranged C–B–E (left-to-right, viewed from bottom). This matches JEDEC TO-92 mechanical dimensions and ensures compatibility with standard through-hole tooling and sockets.

Does PN2484_D75Z support low-current biasing below 10 µA?

Yes, PN2484_D75Z is characterized down to I_C = 1 µA, with h_FE ≥ 30 and noise figure = 3.0 dB at that condition. Its low cutoff currents (I_CBO ≤ 10 nA) and stable V_BE(on) make it suitable for micropower amplifier stages in battery-operated instrumentation.

Is PN2484_D75Z RoHS compliant?

PN2484_D75Z was manufactured under Fairchild's pre-2016 environmental compliance program. While original documentation does not carry explicit "RoHS compliant" labeling, its lead content and halogen-free status align with early RoHS-5 requirements; full compliance verification requires lot-specific test reports from certified labs.

How does PN2484_D75Z differ from MMBT2484?

PN2484_D75Z and MMBT2484 share identical die and electrical specifications-including V_CEO, h_FE, and noise figure-but differ in package: PN2484_D75Z is TO-92 with D75Z tape-and-reel orientation, while MMBT2484 is SOT-23 with "1U" marking. They are not mechanically interchangeable.

What is the maximum operating temperature for PN2484_D75Z?

PN2484_D75Z has a specified junction temperature range of −55°C to +150°C. Its R_θJA = 357 °C/W on FR-4 means sustained operation at +150°C requires ambient temperature ≤ 50°C with no additional heatsinking or airflow.
