onsemi MPS2907ARLRM

Overview

MPS2907ARLRM from onsemi is a PNP silicon general-purpose transistor in TO-92 package, rated for –60 V V_CEO, –600 mA I_C, and 625 mW P_D at T_A = 25°C, with h_FE ≥ 100 at I_C = –1.0 mA and V_CE = –10 V, used in low-voltage switching and linear amplification circuits such as discrete logic inverters and relay drivers.

For engineers reviewing the MPS2907ARLRM datasheet, pinout, applications, or equivalent options, key selection criteria include its –60 V breakdown rating, TO-92 leaded package compatibility, DC current gain across operating current range, saturation voltage under defined drive conditions, and thermal resistance (R_θJA = 200°C/W).

Technical Context

The MPS2907ARLRM operates as a medium-power PNP bipolar junction transistor optimized for general-purpose analog and digital switching. Its electrical behavior is defined by V_(BR)CEO = –60 V, h_FE = 100–300 (I_C = –0.1 to –150 mA), V_CE(sat) ≤ –0.4 V (I_C = –150 mA, I_B = –15 mA), and f_T = 200 MHz - confirming suitability for audio-frequency amplification and sub-MHz switching.

Thermal design relies on R_θJA = 200°C/W and R_θJC = 83.3°C/W, with maximum junction temperature of +150°C. Its TO-92 package supports through-hole mounting and manual rework, and pin configuration follows Style 1: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector.

FAQ

What is the maximum continuous collector current rating for the MPS2907ARLRM?

The MPS2907ARLRM has a maximum continuous collector current (I_C) rating of –600 mA at T_A = 25°C. This rating decreases with rising ambient temperature due to its 5.0 mW/°C derating factor. The device maintains safe operation up to its maximum junction temperature of +150°C, provided thermal design accounts for R_θJA = 200°C/W. Always verify actual I_C in circuit context using worst-case V_CE and duty cycle.

Does the MPS2907ARLRM have a specified noise figure, and under what conditions?

Yes, the MPS2907ARLRM has a specified noise figure (NF) of 2.0 dB at f = 1.0 kHz, V_CE = 10 Vdc, and I_C = –500 µA, per its typical characteristics curve (Figure 8). This value assumes optimal source resistance (R_s ≈ 560 Ω) and applies to low-frequency small-signal amplification. NF increases at higher frequencies and lower collector currents, so designers should consult Figure 8 for application-specific R_s optimization.

What is the pin configuration for the MPS2907ARLRM in its TO-92 package?

The MPS2907ARLRM uses TO-92 Style 1 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. This matches the standard orientation when viewing the flat side of the package with leads pointing downward and the tab at top. The marking "MPS2907A" appears on the flat face, and date code (YWW) follows below. Confirm orientation before PCB layout or hand assembly to avoid reverse-bias damage.

How does the MPS2907ARLRM's f_T of 200 MHz impact its use in switching applications?

The MPS2907ARLRM's f_T = 200 MHz indicates strong high-frequency current gain, supporting fast switching with measured t_on ≤ 45 ns and t_off ≤ 100 ns under specified test conditions. While not intended for RF amplification, this bandwidth ensures clean edge fidelity in digital logic and PWM-driven loads up to ~10 MHz. For reliable operation, maintain adequate base drive (I_B/I_C ≥ 10) and minimize stray capacitance at the base node.

Is the MPS2907ARLRM suitable for operation at elevated ambient temperatures, and what thermal limits apply?

Yes, the MPS2907ARLRM is rated for operation from –55°C to +150°C junction temperature. At T_A = 85°C, its power dissipation must be derated to 325 mW (625 mW – 5.0 mW/°C × 60°C). Its R_θJA = 200°C/W assumes standard JEDEC test board conditions; real-world PCB copper area and airflow significantly affect thermal performance. For sustained high-temperature use, verify junction temperature using T_J = T_A + (P_D × R_θJA) and ensure margin below +150°C.
