onsemi MPSA06RL

Overview

MPSA06RL from ON Semiconductor is a PNP silicon small-signal amplifier transistor in TO-92 package, 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 (at I_C = –2.0 mA), f_T = 170 MHz, and V_CE(sat) ≤ –0.4 V - used in low-noise audio preamplifier stages and discrete gain blocks.

For engineers reviewing the MPSA06RL datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal resistance values (R_JA = 200°C/W), saturation voltage behavior, noise figure (NF ≤ 4.0 dB), and TO-92 terminal mapping to support circuit design, biasing validation, and replacement selection in linear amplification and switching roles.

Technical Context

The MPSA06RL operates as a medium-speed PNP bipolar junction transistor optimized for linear amplification with DC current gain spanning 120–360 across collector currents from –2.0 mA to –50 mA, and maintains f_T ≥ 170 MHz under V_CE = –20 V bias. Its V_BE(sat) ≤ –0.95 V and V_CE(sat) ≤ –0.4 V enable efficient active-region operation in Class-A and emitter-follower configurations.

Thermal performance is defined by R_JA = 200°C/W (free-air) and R_JC = 83.3°C/W, supporting reliable operation across –55°C to +150°C junction temperature range. Cutoff leakage is tightly controlled: I_CBO ≤ –50 nA and I_EBO ≤ –50 nA ensure stable bias in high-impedance input stages.

Compared with MPSA06RL, MPSA05RL trades gain and saturation voltage for cost, while BC557B offers higher h_FE at the expense of bandwidth and noise performance - making MPSA06RL the optimal balance for mid-bandwidth, low-noise linear amplification.

FAQ

What is the maximum collector-emitter voltage rating for MPSA06RL?

The MPSA06RL 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 for reverse-biased operation between collector and emitter terminals. Exceeding –25 V risks avalanche breakdown and permanent device damage. The MPSA06RL must be operated within this limit in all circuit configurations, including transient conditions.

Does MPSA06RL support audio-frequency amplification?

Yes, the MPSA06RL supports audio-frequency amplification with verified performance: f_T ≥ 170 MHz ensures flat gain response up to at least 20 kHz, and NF ≤ 4.0 dB at 1 kHz makes it suitable for microphone preamplifiers and line-level gain stages. Its h_FE range (120–360) and low V_CE(sat) also contribute to low-distortion operation in Class-A audio circuits. The MPSA06RL is widely used in discrete audio designs for these reasons.

What is the thermal resistance from junction to ambient for MPSA06RL?

The thermal resistance from junction to ambient (R_JA) for MPSA06RL is 200°C/W under standard free-air conditions per the ON Semiconductor datasheet. This value assumes no heatsinking and applies to the TO-92 package mounted on a non-copper PCB pad. At T_A = 25°C, the device can dissipate 625 mW; above that ambient temperature, derating is required at 5.0 mW/°C. The MPSA06RL's R_JA directly impacts safe operating area calculations in thermally constrained layouts.

How is the pinout arranged on the MPSA06RL TO-92 package?

The MPSA06RL uses standard TO-92 (Case 29–04, Style 1) pinout: Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector - confirmed by ON Semiconductor's official package drawing and marking orientation (flat side facing viewer, leads down). This arrangement is consistent across the MPSA05/MPSA06 family and differs from NPN counterparts like MPSA13. Correct pin identification is essential to avoid reverse-bias damage during PCB layout or prototyping of the MPSA06RL.

Can MPSA06RL replace MPSA05RL in existing designs?

The MPSA06RL can replace MPSA05RL in most linear amplifier and switching applications due to identical package, voltage/current ratings, and pinout - but with higher minimum h_FE (120 vs. 100) and lower V_CE(sat) (≤ –0.4 V vs. ≤ –0.5 V). These improvements may tighten bias points or reduce conduction loss. However, the MPSA06RL's higher gain could affect stability in poorly compensated circuits. Verify bias stability and thermal margin when substituting MPSA06RL for MPSA05RL.
