Product details

Overview

MPSW06 from ON Semiconductor (formerly Fairchild) is an NPN general-purpose amplifier transistor in TO-226 (TO-92) package, rated for 80 V V_CEO, 500 mA I_C, and 1.0 W P_D at 25°C, with DC current gain h_FE ≥100 at 10 mA, used in low-to-medium power linear amplification and switching circuits.

For engineers reviewing the MPSW06 datasheet, pinout, applications, or equivalent options, key selection criteria include its 80 V breakdown rating, 100 MHz f_T, 0.25 V V_CE(sat) at 100 mA/10 mA drive, thermal resistance R_θJA = 50 °C/W on standard FR-4, and compatibility with general-purpose amplifier designs requiring stable h_FE across 10–100 mA.

Technical Context

The MPSW06 is a silicon NPN bipolar junction transistor fabricated using Process 33, optimized for linear amplification up to 300 mA collector current. Its design emphasizes consistent DC current gain (h_FE ≥100 at both 10 mA and 100 mA), low saturation voltage (0.25 V), and reliable operation across −55°C to +150°C junction temperature range.

It exhibits small-signal bandwidth of 100 MHz at 10 mA/2 V, with SPICE model parameters provided for accurate circuit simulation. Thermal performance is specified for two PCB mounting configurations: standard 1.6" × 1.6" FR-4 and larger 36 mm × 18 mm board with 6 cm² collector pad, yielding R_θJA values of 50 °C/W and lower respectively.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before breakdown; defines upper rail limit in amplifier or switch stages.
I_C (continuous)	500 mA - Absolute max continuous collector current; usable up to 300 mA per design intent for stable gain.
h_FE	≥100 at 10 mA & 100 mA - Ensures predictable current amplification across common bias points without gain roll-off.
f_T	100 MHz - Small-signal bandwidth limit; supports audio and low-RF amplification up to ~10 MHz practical gain-bandwidth.
V_CE(sat)	0.25 V at I_C=100 mA, I_B=10 mA - Low saturation loss enables efficient switching and reduces heat in driver stages.
R_θJA	50 °C/W - Junction-to-ambient thermal resistance on standard FR-4; determines required heatsinking for 1 W dissipation.

Pinout & Package

Package: TO-226 (TO-92), molded plastic case with 3 leads. Standard lead configuration viewed from flat side: Emitter (left), Base (center), Collector (right).

Pin/Terminal	Circuit Role	Design Meaning

Key Features

Feature	Design Value

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
MPSA06	Identical die, same Process 33, but rated for 500 mW P_D (vs. 1.0 W for MPSW06); otherwise matching V_CEO, h_FE, f_T.	Lower power dissipation limits use in higher-current or higher-ambient-temperature environments.	Select MPSA06 where thermal constraints permit lower P_D and board space is critical; MPSW06 preferred for sustained 300 mA operation.
BC547B	Lower V_CEO (45 V), lower f_T (300 MHz typical but not guaranteed), h_FE binning varies (110–800); no official SPICE model provided.	Not suitable for 48 V or industrial 24 V systems due to voltage rating; less predictable gain in production.	Choose BC547B only for cost-sensitive consumer-grade 5–12 V circuits where voltage margin and model fidelity are non-critical.

Compared with MPSA06, the MPSW06 offers double the power dissipation headroom while maintaining identical electrical characteristics; versus BC547B, it provides guaranteed 80 V rating, tighter h_FE consistency, and validated SPICE modeling-critical for industrial and automotive-adjacent designs.

FAQ

What is the maximum continuous collector current for the MPSW06?

The MPSW06 has an absolute maximum continuous collector current (I_C) rating of 500 mA at T_A = 25°C. However, the datasheet specifies its intended use up to 300 mA for stable h_FE and thermal performance. At higher currents, derating per the 8.0 mW/°C thermal coefficient must be applied above 25°C ambient to avoid exceeding the 150°C maximum junction temperature.

Is the MPSW06 pin-compatible with the MPSA06?

Yes, the MPSW06 and MPSA06 share identical TO-226 (TO-92) pinout (E-B-C) and identical die characteristics, including V_CEO, h_FE, and f_T. The primary difference is power dissipation: MPSW06 is rated for 1.0 W, while MPSA06 is rated for 500 mW. No PCB layout change is needed when substituting MPSW06 for MPSA06 where thermal headroom permits.

Does the MPSW06 have a documented SPICE model?

Yes, the MPSW06 includes a complete Gummel-Poon SPICE model in its official datasheet, with verified parameters including Is, Bf, Vaf, Cjc, Cje, Tf, Tr, and Rb. This model is validated for accurate DC, AC, and transient simulation in tools such as LTspice, PSpice, and SIMetrix, enabling precise prediction of gain, bandwidth, and switching behavior in circuit designs.

What is the thermal resistance of the MPSW06 on a standard PCB?

The MPSW06 has a junction-to-ambient thermal resistance (R_θJA) of 50 °C/W when mounted on a standard 1.6" × 1.6" × 0.06" FR-4 PCB. This value assumes no additional copper pour; adding a 6 cm² collector pad reduces R_θJA, improving thermal performance for sustained 300 mA operation. Derating begins at 8.0 mW/°C above 25°C ambient.

Can the MPSW06 be used in switching applications?

Yes, the MPSW06 is suitable for medium-speed switching applications, supported by its 100 MHz f_T, 0.25 V V_CE(sat) at 100 mA/10 mA, and fast stored-charge lifetime (Tf = 516 ps, Tr = 72.15 ns). It is commonly used in relay drivers, LED drivers, and low-power DC motor control where switching frequencies remain below 1 MHz and load currents stay within 300 mA.
