Product details

Overview

MPSA06RL1 from ON Semiconductor is a PNP silicon small-signal amplifier transistor rated for –25 V V_CE, –200 mA I_C, and 625 mW P_D at T_A = 25°C, with h_FE = 120–360 (I_C = –2 mA), f_T = 170 MHz, and V_CE(sat) ≤ –0.4 V (I_C = –50 mA, I_B = –5 mA), used in low-noise audio preamplifier stages and signal switching circuits.

For engineers reviewing the MPSA06RL1 datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, TO-92 package compatibility, DC current gain range, saturation voltage under defined bias, and thermal resistance (R_JA = 200°C/W) for ambient-limited linear operation.

Technical Context

This discrete PNP bipolar junction transistor operates in active, saturation, and cutoff regions with verified breakdown voltages: V_(BR)CEO = –25 V (I_C = –1 mA), V_(BR)CBO = –25 V (I_C = –10 µA), and V_(BR)EBO = –4.0 V (I_E = –10 µA). Its small-signal current gain h_fe spans 120–480 at 1 kHz, and noise figure is ≤ 4.0 dB at I_C = –100 µA, V_CE = –5 V, R_S = 1 kΩ.

Thermal design relies on R_JA = 200°C/W (ambient) and R_JC = 83.3°C/W (case), with derating of 5.0 mW/°C above 25°C for ambient operation and 12 mW/°C above 25°C for case-limited dissipation. Junction temperature is rated from –55°C to +150°C.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP small-signal amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPSA05RL1	Same package and pinout; lower h_FE (100–300), higher V_CE(sat) (≤ –0.5 V), identical V_CE/I_C ratings	Suitable where gain tolerance is relaxed and saturation loss is non-critical	Select when cost sensitivity outweighs need for highest h_FE or lowest V_CE(sat)
BC557B	TO-92 package, same PNP polarity; h_FE = 200–450, V_CE(sat) ≤ –0.65 V, f_T = 100 MHz, higher R_JA = 250°C/W	Better gain spread but reduced RF capability and thermal margin vs. MPSA06RL1	Prefer for general-purpose amplification where bandwidth < 100 MHz suffices and layout allows extra thermal margin

Compared with MPSA06RL1, MPSA05RL1 trades gain and saturation performance for cost, while BC557B offers wider h_FE spread but sacrifices bandwidth and thermal efficiency-making MPSA06RL1 optimal for noise-sensitive, medium-frequency linear amplification with tight V_CE(sat) requirements.

FAQ

What is the maximum collector-emitter voltage rating for MPSA06RL1?

The MPSA06RL1 has a maximum collector-emitter voltage rating of –25 Vdc, specified as V_(BR)CEO with I_C = –1.0 mA and I_B = 0. This rating defines the absolute upper limit before avalanche breakdown occurs in the collector-emitter junction and must not be exceeded in circuit design, especially under transient or inductive load conditions. The MPSA06RL1 maintains this rating across its full operating temperature range.

Does MPSA06RL1 support high-frequency signal amplification?

Yes, the MPSA06RL1 supports high-frequency signal amplification with a minimum transition frequency (f_T) of 170 MHz, measured at I_C = –10 mA, V_CE = –20 V, and f = 100 MHz. This makes it suitable for VHF-band RF driver and oscillator buffer applications. However, gain rolls off above f_T, so system-level bandwidth must be validated with actual bias and load conditions for the MPSA06RL1.

What is the DC current gain range of MPSA06RL1 and how is it tested?

The DC current gain (h_FE) of the MPSA06RL1 ranges from 120 to 360, tested at I_C = –2.0 mA and V_CE = –1.0 V. A second h_FE bin (60–360) is specified at I_C = –50 mA and V_CE = –1.0 V. These values reflect production lot variation and must be accounted for in bias network design. The MPSA06RL1's h_FE remains stable across its –55°C to +150°C junction temperature range.

Is MPSA06RL1 compatible with lead-free reflow soldering processes?

Yes, the MPSA06RL1 is manufactured in a lead-free, RoHS-compliant TO-92 package and qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. Its plastic body and internal construction meet J-STD-020 moisture sensitivity level (MSL) 1 requirements, eliminating bake preconditioning. Always verify thermal profile compatibility with your specific assembly line settings for the MPSA06RL1.

How does the noise performance of MPSA06RL1 compare to other PNP transistors in the same family?

The MPSA06RL1 has a maximum noise figure (NF) of 4.0 dB at I_C = –100 µA, V_CE = –5.0 V, R_S = 1.0 kΩ, and f = 1.0 kHz-matching the MPSA05RL1 and outperforming the MPSA13 (NF ≤ 10 dB). This low-noise trait results from optimized epitaxial base doping and geometry, making the MPSA06RL1 preferred over higher-noise PNP alternatives in microphone preamp and sensor interface roles where signal integrity is critical.
