Product details

Overview

BSV52_D87Z from ON Semiconductor is an NPN switching transistor in SOT-23 package, rated for 12 V V_CEO, 200 mA I_C, and 400 MHz f_T, optimized for high-speed saturated switching at 10–100 mA collector currents in digital logic interfaces and signal routing applications.

For engineers reviewing the BSV52_D87Z datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal limits, switching timing data, and real-world use context - all confirmed against ON Semiconductor's official BSV52 documentation and Fairchild legacy specifications.

Technical Context

The BSV52_D87Z employs a silicon planar epitaxial process (Process 21) with optimized base doping and geometry to achieve fast storage time (13 ns), low V_CE(sat) (0.25 V at I_C=10 mA/I_B=1.0 mA), and stable h_FE across -55°C to +125°C ambient.

Its small-signal characteristics include C_cb = 4.0 pF and C_eb = 4.5 pF at specified bias conditions, supporting clean edge integrity in 10–100 MHz switching waveforms, while its thermal resistance R_θJA = 556°C/W reflects FR-4 PCB mounting constraints.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	12 V - Maximum safe collector-emitter voltage before breakdown under open-base condition.
I_C (continuous)	200 mA - Continuous DC collector current limit without derating at 25°C ambient.
f_T	400 MHz - Transition frequency defining usable bandwidth for small-signal amplification or high-speed switching.
t_s (storage)	13 ns - Time required for minority carriers to clear base region during turn-off; critical for pulse fidelity.
V_CE(sat)	0.25 V at I_C=10 mA/I_B=1.0 mA - Low saturation voltage minimizes power loss in on-state switching.
R_θJA	556°C/W - Junction-to-ambient thermal resistance on standard 40 mm × 40 mm × 1.5 mm FR-4 board.
P_D (max)	225 mW at 25°C - Total power dissipation limit before thermal shutdown or reliability degradation.

Pinout & Package

SOT-23 plastic surface-mount package with 3-pin configuration, marked "B2" on top surface. Designed for automated pick-and-place assembly and reflow soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
E (Emitter)	Current sink terminal	Reference node for base drive; connects to ground or low-side return path in common-emitter switches.
B (Base)	Control input	Accepts current-limited drive (e.g., via 56 Ω or 91 Ω resistor) to saturate or cut off the transistor.
C (Collector)	Current source terminal	Delivers switched load current; requires external pull-up or active driver depending on topology.

Key Features

Feature	Design Value
High-speed switching	13 ns storage time and 12 ns turn-on enable >10 MHz digital signal routing without distortion.
Low V_CE(sat)	0.25 V at I_C/I_B = 10/1 mA reduces conduction loss by ~40% vs. standard general-purpose transistors.
Wide temperature range	-55°C to +150°C operating junction range supports automotive under-hood and industrial control environments.
Small-signal linearity	400 MHz f_T and 4.0 pF C_cb support clean 100 MHz clock buffering with minimal phase shift.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT2222ALT1G	Higher V_CEO (40 V), lower f_T (300 MHz), higher V_CE(sat) (0.3 V typical at same bias).	Better suited for higher-voltage logic interfaces (>15 V), less optimal for >20 MHz signal routing.	Select when robustness at >20 V operation outweighs speed requirements.
BC847BW	Similar SOT-323 package, 450 MHz f_T, but lower I_C rating (100 mA continuous) and tighter h_FE spread.	Preferred for ultra-compact layouts where board space is constrained and current demand ≤50 mA.	Choose for space-constrained designs requiring marginally faster switching at reduced current capacity.

Compared with MMBT2222ALT1G and BC847BW, the BSV52_D87Z offers the best balance of speed (400 MHz f_T), low saturation voltage (0.25 V), and 200 mA current capability in the industry-standard SOT-23 footprint - making it ideal for mid-frequency digital switching where thermal and timing margins are tight.

FAQ

What is the maximum operating temperature for the BSV52_D87Z?

The BSV52_D87Z has a specified operating junction temperature range of -55°C to +150°C. Its storage temperature matches this range. The device's thermal resistance (R_θJA = 556°C/W) means that at 25°C ambient and full 225 mW dissipation, junction temperature reaches ~145°C - well within safe limits. Always verify actual board-level thermal performance using the BSV52_D87Z's published power derating curve.

Does the BSV52_D87Z support 5 V logic interfacing?

Yes, the BSV52_D87Z supports 5 V logic interfacing: its V_CEO = 12 V and V_CES = 20 V exceed 5 V rail requirements, and its V_BE(sat) = 0.7–0.85 V ensures reliable turn-on with standard 5 V TTL or CMOS drivers. At I_B = 1.0 mA and I_C = 10 mA, the BSV52_D87Z achieves V_CE(sat) = 0.25 V - confirming robust saturation under 5 V drive conditions.

What is the pin configuration of the BSV52_D87Z in SOT-23?

The BSV52_D87Z uses standard SOT-23 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed from top, marking side up, leads pointing downward). This matches JEDEC MO-178AB and is confirmed by Fairchild's original BSV52 datasheet diagrams and ON Semiconductor's cross-reference documentation for legacy Fairchild parts.

Can the BSV52_D87Z replace the MMBT2222A in high-speed applications?

The BSV52_D87Z can replace the MMBT2222A in high-speed applications where speed and low V_CE(sat) are prioritized over higher voltage rating: BSV52_D87Z offers 400 MHz f_T vs. 300 MHz and 0.25 V V_CE(sat) vs. 0.3 V at matched bias. However, its 12 V V_CEO is lower than MMBT2222A's 40 V - so verify voltage margins before substitution in the BSV52_D87Z design.

Is the BSV52_D87Z RoHS compliant and halogen-free?

Yes, the BSV52_D87Z is RoHS compliant and halogen-free. As a post-Fairchild-integration ON Semiconductor part, it conforms to ON Semiconductor's environmental policy and meets JEDEC JS709E and IEC 61249-2-21 standards. The "D87Z" suffix aligns with ON Semiconductor's packaging and compliance coding convention for green-compliant SOT-23 devices.
