Product details

Overview

MPS3563 from onsemi is an NPN silicon small-signal transistor in TO-92 package, rated for 12 V_CEO, 30 V_CBO, 2.0 V_EBO, 50 mA continuous collector current, and 350 mW power dissipation at T_A = 25°C - used in low-power RF amplification, oscillator circuits, and general-purpose switching in consumer audio and signal conditioning stages.

For engineers reviewing the MPS3563 datasheet, pinout, applications, or equivalent options, key selection considerations include its 1500 MHz f_T, 1.7 pF C_obo at 10 V_CB, h_fe range of 20–250 at 8 mA/10 V, and TO-92 mechanical compatibility with legacy through-hole designs requiring stable gain and low-noise small-signal operation.

Technical Context

The MPS3563 operates as a discrete NPN bipolar junction transistor optimized for RF amplifier and oscillator functions up to 500 MHz, with verified small-signal current gain (h_fe) of 20–250 and transition frequency (f_T) of 1500 MHz under 8 mA I_C/10 V V_CE conditions. Its 1.7 pF output capacitance and 2.0 V emitter-base breakdown support stable high-frequency biasing in tuned circuits.

Thermal design is constrained by R_JA = 357°C/W and R_JC = 147°C/W, with maximum junction temperature rated from −55°C to +150°C. The device uses standard TO-92 leadframe construction with Pb-free plating options (MPS3563G, MPS3563RLRAG) and is specified for DC and small-signal AC operation only - not intended for power switching or linear regulator applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	12 Vdc - maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration.
f_T	1500 MHz - usable small-signal amplification bandwidth limit at I_C = 8 mA, V_CE = 10 V, critical for VHF oscillator and RF preamp design.
h_fe	20–250 - small-signal current gain range at I_C = 8 mA, V_CE = 10 V, 1 kHz; determines base drive requirements and stage gain stability.
C_obo	1.7 pF - output capacitance at V_CB = 10 V, IE = 0, f = 1 MHz; directly impacts impedance matching and tuning in resonant circuits.
P_D @ T_A	350 mW - maximum power dissipation at ambient 25°C; derates 2.8 mW/°C above 25°C, limiting usable DC bias in compact enclosures.
V_EBO	2.0 Vdc - maximum reverse-biased emitter-base voltage before conduction; constrains base bias network headroom in low-voltage designs.

Pinout & Package

Package: TO-92 (Case 29-11, Style 17), 3-lead through-hole plastic package with standardized lead spacing (2.54 mm pitch), JEDEC-compliant outline, and Pb-free plating available per MPS3563G and MPS3563RLRAG variants.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink terminal; connects to ground or low-impedance return path; polarity-sensitive for proper BJT biasing.
2	Base	Control input; requires current-limited drive (typically ≤1 mA) to achieve saturation or linear operation.
3	Collector	Current source terminal; connects to supply rail or load; carries full output current and dissipates majority of device power.

Key Features

Feature	Design Value
High f_T	1500 MHz enables stable amplification and oscillation up to 500 MHz without external neutralization.
Low C_obo	1.7 pF minimizes loading on tank circuits and improves Q-factor in LC-based RF stages.
Wide h_fe range	20–250 supports consistent gain across production lots when used with emitter degeneration or feedback.
Pb-free variants	MPS3563G and MPS3563RLRAG meet RoHS compliance without performance trade-offs or requalification.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2N3904	Lower f_T (300 MHz), higher V_EBO (6 V), same TO-92 package and pinout (E-B-C).	Less suitable for >200 MHz oscillator use; better for general-purpose switching where V_EBO margin is critical.	Select 2N3904 only if RF performance is not required and higher emitter-base voltage tolerance is needed.
BC547B	Higher h_fe (200–450), lower V_CEO (45 V), same f_T range (~300 MHz), TO-92 package with E-B-C pinout.	Better DC gain stability but limited high-frequency response; preferred for audio amplification over RF.	Choose BC547B for low-frequency analog gain stages where bandwidth beyond 100 MHz is unnecessary.

Compared with MPS3563, the 2N3904 offers wider V_EBO margin but lacks RF capability, while BC547B delivers higher DC gain yet falls short in VHF oscillator applications due to lower f_T; MPS3563 remains optimal where 500 MHz operation and low C_obo are essential.

FAQ

What is the maximum operating frequency of the MPS3563?

The MPS3563 has a transition frequency (f_T) of 1500 MHz under test conditions of I_C = 8 mA and V_CE = 10 V. This specifies the frequency at which small-signal current gain drops to unity. Practical stable amplification is confirmed up to 500 MHz in oscillator and RF amplifier applications per functional test data in the official datasheet for MPS3563.

Is the MPS3563 pin-compatible with the MPS918?

No - the MPS3563 and MPS918 share the same TO-92 package and Style 17 pinout (Emitter-Base-Collector), but differ in electrical ratings: MPS3563 has V_CEO = 12 V and V_EBO = 2.0 V, while MPS918 specifies V_CEO = 15 V and V_EBO = 3.0 V. Substitution requires verification of voltage margins in the target circuit.

Does the MPS3563 support Pb-free assembly processes?

Yes - the MPS3563G and MPS3563RLRAG variants are explicitly designated as Pb-free in the official ordering information. Both comply with RoHS Directive 2011/65/EU and support standard reflow soldering profiles per onsemi's Soldering and Mounting Techniques Reference Manual.

What is the thermal resistance junction-to-ambient for the MPS3563?

The MPS3563 has a thermal resistance R_JA of 357°C/W when mounted on a typical printed circuit board, as measured per JEDEC JESD51-2. This value assumes standard PCB copper area and no heatsinking; actual thermal performance depends on board layout, airflow, and adjacent heat sources.

Can the MPS3563 be used in linear regulator pass transistor applications?

No - the MPS3563 is characterized and qualified only for small-signal amplification and switching. Its maximum power dissipation is 350 mW at 25°C ambient, and it lacks Safe Operating Area (SOA) curves or linear regulation-specific parameters such as SOA-limited V_CE/I_C combinations. Use dedicated power transistors for linear regulator designs.
