onsemi MPS2907ARLRAG

Overview

MPS2907ARLRAG from onsemi is a PNP silicon small-signal transistor designed for general-purpose amplification and switching in low-power analog and digital circuits, with DC current gain (h_FE) of 100 at I_C = 10 mA, V_CE = -1 V; maximum collector-emitter voltage (V_CEO) of -60 V; continuous collector current (I_C) rating of -600 mA; and power dissipation (P_D) of 625 mW at 25°C ambient. It is commonly used in discrete logic inverters, level shifters, and bias networks in industrial control modules.

For engineers reviewing the MPS2907ARLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include verified DC current gain consistency across production lots, guaranteed V_CEO derating above 25°C, thermal resistance (R_θJA) of 200°C/W in TO-92 package, and compatibility with legacy through-hole PCB layouts requiring lead-forming tolerance.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with defined base-emitter turn-on voltage (V_BE(on)) of -0.85 V at I_C = -10 mA and I_B = -1 mA. Its complementary NPN counterpart is the MPS2222A, enabling push-pull configurations in Class-A amplifier stages.

The device features uniform current gain distribution (h_FE = 100–300) across the specified test conditions, and its TO-92 package supports manual soldering and wave soldering per J-STD-020C, with junction-to-ambient thermal resistance confirmed at 200°C/W under standard mounting conditions.

FAQ

What is the maximum operating temperature for the MPS2907ARLRAG?

The MPS2907ARLRAG has a maximum junction temperature (T_J) of 150°C. Operation above this limit risks permanent degradation of h_FE and increased leakage current. Derating is required above 25°C ambient per R_θJA = 200°C/W; for example, at 75°C ambient, maximum allowable power dissipation drops to 312.5 mW. Always verify thermal design using actual board layout and airflow conditions before finalizing the MPS2907ARLRAG in high-temperature environments.

Is the MPS2907ARLRAG pin-compatible with the MPS2222A?

No, the MPS2907ARLRAG is not pin-compatible with the MPS2222A. While both are TO-92 packaged transistors, the MPS2222A is an NPN device with emitter-base-collector (E-B-C) pin order, whereas the MPS2907ARLRAG is a PNP device with collector-base-emitter (C-B-E) pin order when viewed from the flat side with leads down. Swapping them without board revision will result in incorrect biasing and functional failure. Always confirm pinout using the official onsemi MPS2907ARLRAG datasheet before layout reuse.

Does the MPS2907ARLRAG support lead-free soldering processes?

Yes, the MPS2907ARLRAG is qualified for lead-free soldering per J-STD-020C. Its TO-92 package withstands peak reflow temperatures up to 260°C for 10 seconds, and the device meets MSL-1 (moisture sensitivity level 1) requirements with unlimited floor life at ≤30°C/60% RH. The lead finish is matte tin, fully compatible with SAC305 and other common lead-free alloys. No pre-bake is required prior to reflow, simplifying manufacturing for the MPS2907ARLRAG in RoHS-compliant production lines.

What is the typical V_BE for the MPS2907ARLRAG at I_C = -1 mA?

The typical base-emitter voltage (V_BE) for the MPS2907ARLRAG at I_C = -1 mA and V_CE = -1 V is -0.65 V, per onsemi's published characterization data. This value is 0.2 V lower than the -0.85 V specified at I_C = -10 mA, reflecting the logarithmic relationship between V_BE and collector current. Accurate bias network design for the MPS2907ARLRAG must account for this variation-especially in low-current applications like sensor interfaces or standby logic-where even small V_BE shifts affect quiescent point stability.

Can the MPS2907ARLRAG be used in avalanche mode?

No, the MPS2907ARLRAG is not rated or characterized for avalanche operation. Its absolute maximum V_CEO rating of -60 V applies only under normal forward-active or saturated switching conditions. Exceeding this voltage-even briefly-may cause irreversible junction breakdown due to lack of controlled avalanche energy rating (E_AS) or ruggedness testing. For transient protection or clamping applications requiring controlled avalanche behavior, select purpose-built devices such as onsemi's PZTA44 or dedicated TVS diodes instead of relying on the MPS2907ARLRAG.
