Product details
Overview
PN2484_D27Z from Fairchild Semiconductor is an NPN general-purpose amplifier transistor in TO-92 package, rated for 60 V VCEO, 100 mA IC, and 350 mW PD at TA = 25°C, optimized for low-noise, high-gain amplification at collector currents from 1 µA to 50 mA in analog signal conditioning circuits.
For engineers reviewing the PN2484_D27Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 6.0 pF Cobo, 3.0 dB noise figure at 1 kHz, hFE range of 30–800, VCE(sat) ≤ 0.35 V, and thermal resistance RθJA = 357 °C/W on FR-4 PCB.
Technical Context
The PN2484_D27Z implements a silicon planar epitaxial NPN structure fabricated in Fairchild's Process 07, sharing electrical characteristics with the 2N5088 family. It operates across –55°C to +150°C junction temperature range and supports stable DC amplification with hFE ≥ 200 at IC = 100 µA and VCE = 5.0 V.
Its small-signal performance includes 6.0 pF output capacitance (Cobo) and 6.0 pF input capacitance (Cibo) at specified bias conditions, enabling predictable frequency response in audio and low-frequency amplifier stages where noise and gain linearity are critical.
Key Specifications

| VCEO | 60 V - maximum safe collector-emitter voltage before breakdown under open-base condition |
| IC (max) | 100 mA - continuous collector current limit defining linear operation ceiling |
| PD | 350 mW - total power dissipation on FR-4 PCB at 25°C ambient, derating 2.8 mW/°C above |
| hFE | 30–800 - DC current gain range across IC = 1 µA to 10 mA, supporting wide bias flexibility |
| NF | 3.0 dB - noise figure at IC = 10 µA, VCE = 5.0 V, RS = 10 kΩ, 1 kHz, BW = 200 Hz |
| Cobo | 6.0 pF - output capacitance at VCB = 5.0 V, f = 140 kHz, limiting high-frequency gain roll-off |
Pinout & Package
PN2484_D27Z is supplied in TO-92 through-hole package with standard lead configuration: Collector (C), Base (B), Emitter (E) arranged left-to-right when flat side faces viewer and leads point downward.
| Pin/Terminal | Circuit Role | Design Meaning |

| B (Base) | Control input terminal | Accepts bias current to modulate collector current; requires VBE(on) ≈ 0.5–0.7 V for turn-on |
| E (Emitter) | Current return path | Serves as common reference node; carries sum of base and collector currents; grounded or biased via resistor |
Key Features

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 |
|---|---|---|---|
| 2N5088 | Identical absolute maximum ratings and electrical characteristics per Fairchild documentation; same Process 07 fabrication | No functional difference; used interchangeably in all published designs referencing PN2484/MMBT2484 | Select 2N5088 when requiring legacy part number continuity or distributor stock alignment |
| MMBT2484 | SOT-23 surface-mount variant with identical electrical specs but different thermal resistance (RθJA = 200 °C/W vs. 357 °C/W) and pinout (Emitter-Base-Collector) | Requires PCB redesign for SMT assembly; better suited for space-constrained, high-density layouts | Choose MMBT2484 only when migrating from through-hole to surface-mount and thermal management permits lower power dissipation |
Compared with 2N5088 and MMBT2484, PN2484_D27Z offers identical core amplification performance in TO-92 packaging with documented 357 °C/W RθJA on FR-4, making it optimal for prototyping, repair, and low-volume through-hole production where thermal margin and mechanical robustness are prioritized over board density.

FAQ
What is the pin configuration of PN2484_D27Z?
PN2484_D27Z uses the standard TO-92 pinout: when viewing the flat side with leads pointing downward, the left-to-right order is Collector (C), Base (B), Emitter (E). This matches the marking "1U" on the device body and is confirmed in Fairchild's PN2484/MMBT2484 Rev B datasheet Figure 1.0.
Does PN2484_D27Z support operation at elevated temperatures?
Yes, PN2484_D27Z is rated for junction temperatures from –55°C to +150°C. Its thermal resistance RθJA is 357 °C/W on FR-4 PCB, meaning it can sustain full 350 mW dissipation only below ~50°C ambient unless heatsinking is applied-critical for use in enclosed industrial enclosures or automotive under-dash locations.
What is the typical noise performance of PN2484_D27Z?
PN2484_D27Z achieves a noise figure of 3.0 dB at IC = 10 µA, VCE = 5.0 V, RS = 10 kΩ, f = 1.0 kHz, and BW = 200 Hz. This low-noise capability makes PN2484_D27Z especially suitable for microphone preamplifiers and precision sensor front-ends where signal-to-noise ratio is critical.
Can PN2484_D27Z replace 2N5088 in existing designs?
Yes, PN2484_D27Z is electrically and mechanically interchangeable with 2N5088: both share identical absolute maximum ratings, electrical characteristics, TO-92 package, and pinout. Fairchild explicitly states "See 2N5088 for characteristics" in the PN2484 datasheet, confirming functional equivalence and direct substitution.
What packaging option does PN2484_D27Z use?
PN2484_D27Z is supplied in tape-and-reel format per EOL code D27Z, with 2,000 units per reel, configured for machine Option "E" (J), where the first wire off is the Emitter and the flat side of the transistor is on the bottom-matching standard TO-92 orientation for automated insertion.
