Product details
Overview
FJV992PMTF from ON Semiconductor is a PNP epitaxial silicon transistor optimized for audio-frequency low-noise amplification, with -120 V collector-emitter breakdown voltage (BVCEO), -50 mA continuous collector current (IC), 300 mW power dissipation, 50 MHz current gain bandwidth product (fT), and 40 mV noise voltage (NV) at 10 Hz–1 kHz - deployed in compact SOT-23 packages for space-constrained analog front-ends.
For engineers reviewing the FJV992PMTF datasheet, pinout, applications, or equivalent options, key selection criteria include its low-noise performance in small-signal amplification, complementary pairing with FJV1845, hFE2 classification range (200–400), SOT-23 terminal mapping, and suitability for battery-powered audio preamplifiers and sensor signal conditioning circuits.
Technical Context
The FJV992PMTF operates as a general-purpose PNP bipolar junction transistor with fixed-emitter biasing capability, designed for linear amplification rather than switching. Its hFE2 classification (200–400) ensures predictable DC current gain across production lots, while fT = 50 MHz supports stable operation up to mid-audio frequencies without phase inversion or gain collapse.
Thermal derating begins at 25°C ambient, with linear reduction to zero power dissipation at 150°C junction temperature. The device exhibits low output capacitance (Cob = 3 pF at VCB = -30 V), enabling high-impedance node isolation and minimal Miller effect in cascode or common-emitter configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| BVCEO | -120 V - Supports rail-to-rail operation in ±60 V supply systems without breakdown. |
| IC | -50 mA - Enables sufficient drive for line-level audio stages and low-power sensor interfaces. |
| fT | 50 MHz - Ensures flat gain response through 20 kHz with margin for harmonic content. |
| NV | 40 mV (10 Hz–1 kHz) - Meets low-noise requirements for microphone preamps and instrumentation amplifiers. |
| VCE(sat) | -300 mV @ IC = -10 mA, IB = -1 mA - Minimizes voltage headroom loss in emitter-follower buffers. |
| hFE2 | 200–400 - Guarantees consistent bias point stability across temperature and unit-to-unit variation. |
| Cob | 3 pF @ VCB = -30 V - Reduces capacitive loading on preceding gain stages in multi-stage amplifiers. |
Pinout & Package
SOT-23 plastic surface-mount package with gull-wing leads; 1.90 mm × 1.30 mm footprint, 1.14 mm max height, and JEDEC-compliant thermal pad layout for reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Current-controlled input node | Receives reverse-biased base current to modulate collector-emitter conduction; requires external bias network for stable Q-point. |
| 2 (Emitter) | Common reference terminal | Connected to higher-potential rail in PNP configuration; serves as current source output in emitter-follower topologies. |
| 3 (Collector) | Output current terminal | Delivers amplified current to load; polarity must be negative relative to emitter for active-region operation. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise amplification | 40 mV noise voltage over 10 Hz–1 kHz band enables clean signal recovery in mic/ECG front-ends. |
| Complementary pairing | Designed as direct complement to NPN FJV1845 for push-pull and differential amplifier designs. |
| High BVCEO | -120 V rating allows use in industrial analog signal chains with elevated supply rails or transient immunity. |
| SOT-23 footprint | Standardized 3-pin package enables automated placement and compatibility with legacy PCB layouts. |
| hFE2 classification | 200–400 DC gain binning reduces need for post-production gain trimming in production assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT992 | Same die, identical electrical specs, but marked per ON Semiconductor nomenclature; no underscore in part number. | No functional difference; used interchangeably where updated ordering system is required. | Select MMBT992 when sourcing from ON Semiconductor's current ERP system or distributor catalogs aligned with post-Fairchild branding. |
| BC807-40 | Lower BVCEO (-45 V), lower fT (100 MHz but tested at IC = -100 mA), hFE range 250–630, same SOT-23 package. | Not suitable for >±45 V rails; higher gain spread increases need for circuit trimming. | Choose BC807-40 only for cost-sensitive, low-voltage (<30 V) consumer audio where noise spec is secondary. |
Compared with MMBT992 and BC807-40, the FJV992PMTF delivers superior high-voltage robustness and tighter hFE2 binning for precision analog designs, while maintaining full SOT-23 compatibility and proven low-noise behavior in audio-frequency signal paths.

FAQ
What is the maximum collector-emitter voltage rating for FJV992PMTF?
The FJV992PMTF has a guaranteed minimum collector-emitter breakdown voltage (BVCEO) of -120 V at IC = -1 mA with base open. This rating allows safe operation in circuits with up to ±60 V supply rails and provides margin against transient voltage spikes in industrial analog signal paths. Derating applies above 25°C ambient per the published power derating curve.
Is FJV992PMTF pin-compatible with FJV1845?
No - FJV992PMTF is a PNP transistor while FJV1845 is an NPN device; they share complementary electrical characteristics but opposite polarity and pinout orientation. In SOT-23, FJV992PMTF uses pin 1=Base, 2=Emitter, 3=Collector, whereas FJV1845 uses pin 1=Base, 2=Collector, 3=Emitter. Direct substitution without board revision is not possible.
What does the 'P' suffix in FJV992PMTF indicate?
The 'P' in FJV992PMTF denotes the hFE2 classification bin (200–400), per Fairchild's original marking convention. It is not a package code - the 'MTF' suffix confirms the SOT-23 package with tape-and-reel packaging. This binning ensures predictable DC current gain for production consistency in bias-critical analog designs.
Can FJV992PMTF be used in switching applications?
The FJV992PMTF is characterized and optimized for linear amplification, not switching. While it can operate in saturation, its VCE(sat) = -300 mV and relatively slow turn-off behavior (due to minority-carrier storage) make it less suitable for high-speed digital switching. For switching, ON Semiconductor recommends dedicated small-signal switches like NSS12201MR6T1.
Where is the official datasheet for FJV992PMTF hosted?
The official datasheet for FJV992PMTF is hosted on ON Semiconductor's website under document number FJV992-D, Rev. C (August 2004), accessible via www.onsemi.com/part/FJV992PMTF. It remains valid for technical specifications, absolute maximum ratings, and typical characteristics - including noise voltage, fT, and hFE2 classification data.
