Product details
Overview
BC183_D75Z from Fairchild Semiconductor is an NPN general-purpose bipolar junction transistor (BJT) designed for low-power amplification and switching in analog and digital circuits. It features a 45 V collector-base voltage, 30 V collector-emitter voltage, 100 mA DC collector current, 350 mW power dissipation at 25°C, and a current gain bandwidth product of 150 MHz - enabling use in audio preamplifiers, signal conditioning stages, and low-speed logic interface circuits.
For engineers reviewing the BC183_D75Z datasheet, pinout, applications, or equivalent options, key selection considerations include its TO-92 package compatibility, guaranteed hFE range (40–80 at IC = 100 mA), VCE(sat) ≤ 0.6 V under high-current saturation, noise figure of 10 dB at 1 kHz, and thermal stability across –55°C to +150°C junction temperature.
Technical Context
The BC183_D75Z operates as a standard NPN BJT with fixed emitter-base and collector-base junction structures optimized for linear amplification and saturated switching. Its hFE exhibits strong current dependence - ranging from 125 to 900 at IC = 2 mA but narrowing to 40–80 at IC = 100 mA - indicating design intent for both small-signal gain and medium-current switching roles.
It delivers VBE(on) between 0.55 V and 0.7 V at IC = 2 mA and VCE = 5 V, supports low-noise operation (NF = 10 dB @ RG = 2 kΩ, f = 1 kHz), and maintains COB = 5 pF at VCE = 10 V, f = 1 MHz - confirming suitability for RF-coupled amplifier stages up to ~150 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCBO | 45 V - maximum reverse bias voltage the collector-base junction can withstand without breakdown |
| VCEO | 30 V - maximum collector-emitter voltage before avalanche conduction in open-base configuration |
| IC (DC) | 100 mA - continuous DC collector current rating defining safe linear/switching operating envelope |
| PC (Ta=25°C) | 350 mW - thermal power limit at ambient temperature, requiring derating above 25°C |

Pinout & Package
BC183_D75Z is housed in a through-hole TO-92 plastic package with standardized lead orientation: flat side facing viewer, leads downward, left-to-right pin order is Collector (1), Base (2), Emitter (3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Collector) | Main current output terminal | Carries amplified load current; connected to supply rail or pull-up resistor in common-emitter configurations |

|---|---|
| Guaranteed hFE range at high current | 40–80 at IC = 100 mA ensures predictable saturation behavior in switching applications |
| Low VCE(sat) | ≤ 0.6 V at IC = 100 mA / IB = 5 mA minimizes conduction loss in active-low switch designs |
| Stable noise performance | 10 dB NF at 1 kHz supports low-noise preamplifier stages in sensor interfaces |
| Wide junction temperature range | –55°C to +150°C operation enables deployment in industrial and automotive under-hood environments |
| TO-92 mechanical compatibility | Standardized footprint allows drop-in replacement with BC107, BC108, BC109, and other legacy NPN transistors |

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 |
|---|---|---|---|
| BC107 | Slightly lower fT (120 MHz), identical TO-92 package and pinout, hFE min 110 at IC = 2 mA | Better small-signal gain uniformity but less consistent high-current hFE | Select BC107 when prioritizing low-noise small-signal amplification over high-current switching linearity |
| BC547 | Higher IC rating (100 mA same), higher PC (500 mW), improved hFE spread (110–800), same pinout | Enhanced thermal margin and broader gain range for wider operating conditions | Select BC547 when extended power handling or wider hFE variability is required in production designs |
Compared with BC107 and BC547, the BC183_D75Z offers tighter high-current hFE control (40–80) and lower VCE(sat) at 100 mA, making it preferable for cost-sensitive switching applications where predictable saturation voltage matters more than ultra-low noise or wide gain spread.

FAQ
What is the maximum collector-emitter voltage rating for BC183_D75Z?
The BC183_D75Z has a maximum collector-emitter voltage (VCEO) rating of 30 V at TC = 25°C. This rating applies under open-base conditions and must be derated linearly with increasing junction temperature per the device's thermal characteristics. Exceeding this voltage risks avalanche breakdown and permanent damage to the BC183_D75Z.
Does BC183_D75Z have a specified noise figure, and under what conditions?
Yes, the BC183_D75Z specifies a noise figure (NF) of 10 dB at 1 kHz, measured with VCE = 5 V, IC = 200 mA, and a source resistance (RG) of 2 kΩ. This value reflects its suitability for low-frequency analog amplification tasks, and the BC183_D75Z maintains this performance across its rated temperature range.
What is the pin configuration of BC183_D75Z in its TO-92 package?
The BC183_D75Z uses a standard TO-92 package with pin 1 as Collector, pin 2 as Base, and pin 3 as Emitter - viewed with the flat side facing the user and leads pointing downward. This pinout matches industry-standard NPN transistors like BC107 and BC547, ensuring direct PCB layout compatibility for BC183_D75Z.
Can BC183_D75Z be used in switching applications, and what saturation performance does it offer?
Yes, the BC183_D75Z is qualified for switching use with VCE(sat) ≤ 0.6 V at IC = 100 mA and IB = 5.0 mA. Its guaranteed hFE range of 40–80 at that current ensures reliable saturation, and the BC183_D75Z achieves fast turn-on/turn-off times due to its 150 MHz fT, supporting operation up to several hundred kHz.
What is the storage and junction temperature range for BC183_D75Z?
The BC183_D75Z supports a storage and junction temperature range of –55°C to +150°C. This wide thermal specification allows deployment in harsh environments such as automotive engine compartments or industrial control cabinets, and the BC183_D75Z retains electrical performance within datasheet limits across this full range.
