Product details

Overview

2N7052 from onsemi is a small-signal NPN bipolar junction transistor (BJT) rated for 60 V V_CEO, 100 mA I_C, and 350 mW P_D at T_A = 25 °C, optimized for general-purpose amplification and switching in low-power analog and digital circuits.

For engineers reviewing the 2N7052 datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain (h_FE = 100–300 at I_C = 10 mA), transition frequency (f_T = 250 MHz), and complementary PNP pairing with 2N7051 in discrete amplifier stages.

Technical Context

The 2N7052 operates as a silicon planar epitaxial NPN transistor with a grounded-emitter configuration, supporting linear amplification up to 250 MHz and saturated switching with typical V_CE(sat) = 0.25 V at I_C = 10 mA and I_B = 1 mA.

Its base-emitter junction exhibits V_BE(on) ≈ 0.75 V at I_C = 10 mA, and its thermal resistance R_θJA is 357 °C/W, indicating suitability for surface-mount or through-hole PCB layouts without forced airflow in ambient-temperature environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - maximum collector-emitter voltage before breakdown under open-base condition
I_C	100 mA - continuous collector current rating defining safe linear/saturated operation
P_D	350 mW - total power dissipation at 25 °C ambient, derating linearly above that temperature
h_FE	100–300 - DC current gain range at I_C = 10 mA, V_CE = 1 V, critical for bias stability
f_T	250 MHz - transition frequency where current gain drops to unity, limiting high-frequency amplification bandwidth
V_CE(sat)	0.25 V (typ.) - low saturation voltage enabling efficient switching in logic-level interfaces

Pinout & Package

2N7052 is housed in a TO-92 plastic package with standard through-hole mounting and three-terminal lead configuration.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (E)	Current sink terminal	Reference node for biasing; connects to ground or low-impedance return path in common-emitter amplifiers
Base (B)	Control input terminal	Receives forward-bias current to modulate collector current; requires series resistor for stable DC bias
Collector (C)	Current source terminal	Delivers amplified output current; connects to load or next-stage input in multi-stage designs

Key Features

Feature	Design Value
High f_T	250 MHz enables RF preamplifier and broadband signal conditioning up to VHF band
Low V_CE(sat)	0.25 V typical ensures minimal conduction loss in digital switching and level-shifting applications
Wide h_FE range	100–300 supports robust bias design across manufacturing lots without individual trimming
TO-92 compatibility	Standard footprint allows drop-in replacement in legacy designs using industry-common 3-pin through-hole layout

Equivalent & Alternatives

The following parts are listed as comparable options for similar small-signal NPN transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC547B	V_CEO = 45 V, h_FE = 200–450, f_T = 300 MHz	Lower voltage rating limits use in 60 V rail systems; higher f_T supports wider bandwidth	Select when higher gain and frequency response are prioritized over voltage headroom
MPSA18	V_CEO = 45 V, h_FE = 100–300, f_T = 600 MHz	Higher f_T enables RF amplifier use beyond 250 MHz; same gain range but lower voltage tolerance	Prefer for VHF oscillator or tuned amplifier where 45 V suffices and speed is critical

Compared with BC547B and MPSA18, the 2N7052 provides superior 60 V V_CEO headroom for industrial control and automotive body electronics, while maintaining sufficient f_T and h_FE for general-purpose analog and switching roles without requiring layout changes.

FAQ

What is the maximum collector-emitter voltage rating for the 2N7052?

The 2N7052 has a maximum collector-emitter voltage (V_CEO) rating of 60 V under open-base conditions. This specification defines the upper limit of voltage the device can withstand between collector and emitter without breakdown, making it suitable for circuits operating up to 48 V nominal rails with safety margin. Exceeding this voltage risks permanent damage to the 2N7052 junction structure.

Does the 2N7052 have a specified transition frequency (f_T)?

Yes, the 2N7052 has a typical transition frequency (f_T) of 250 MHz, measured at I_C = 10 mA and V_CE = 10 V. This parameter indicates the frequency at which the transistor's small-signal current gain drops to unity, directly influencing usable bandwidth in amplifier and RF applications. The 2N7052's f_T supports stable operation in audio and low-VHF signal paths.

What is the DC current gain (h_FE) range for the 2N7052?

The 2N7052 exhibits a DC current gain (h_FE) range of 100 to 300 when tested at I_C = 10 mA and V_CE = 1 V. This wide but controlled spread allows reliable bias design across production lots without individual calibration. Designers should use the minimum value (100) for worst-case saturation analysis and the maximum (300) for linear-mode gain margin assessment in the 2N7052.

Is the 2N7052 available in surface-mount packaging?

No, the standard 2N7052 is offered exclusively in the through-hole TO-92 package. onsemi does not list an SMD variant (e.g., SOT-23 or SC-70) for this specific part number. For surface-mount alternatives with similar electrical characteristics, engineers should evaluate parts such as MMBT3904 or PN2222A, verifying pin compatibility and thermal performance against the 2N7052 requirements.

How does the 2N7052 compare to the 2N7051 in circuit design?

The 2N7052 (NPN) and 2N7051 (PNP) form a complementary pair with matched voltage, current, and gain specifications-both rated for 60 V V_CEO, 100 mA I_C, and h_FE = 100–300. This symmetry enables balanced Class-A or AB amplifier stages, differential pairs, and H-bridge driver topologies where matched turn-on thresholds and gain profiles are essential for minimizing distortion in the 2N7052/2N7051 combination.
