onsemi P2N2907ARL1

Overview

P2N2907ARL1 from onsemi is a PNP silicon bipolar junction transistor (BJT) designed for general-purpose amplification and switching in low-power analog and digital circuits. It features −60 V V_CEO, −600 mA I_C, 625 mW power dissipation at T_A = 25°C, 200 MHz f_T, and TO-92 package - used in discrete amplifier stages, level shifters, and relay drivers.

For engineers reviewing the P2N2907ARL1 datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, −60 V breakdown rating, saturation voltage under −150 mA/−15 mA drive, thermal resistance (R_JA = 200°C/W), and Pb-free TO-92 packaging compliance.

Technical Context

The P2N2907ARL1 operates as a medium-speed, medium-current PNP BJT with DC current gain (h_FE) ranging from 75 to 300 depending on collector current (−0.1 mA to −150 mA). Its small-signal performance includes f_T = 200 MHz at I_C = −50 mA and V_CE = −20 V, with C_obo = 8.0 pF and C_ibo = 30 pF.

Switching behavior is characterized by t_on ≤ 50 ns, t_off ≤ 110 ns, and t_s ≤ 80 ns under specified test conditions (V_CC = −30 V, I_C = −150 mA, I_B1 = −15 mA). Saturation is defined at V_CE(sat) = −0.4 V (I_C = −150 mA, I_B = −15 mA) and −1.6 V (I_C = −500 mA, I_B = −50 mA).

FAQ

What is the maximum collector-emitter voltage rating for the P2N2907ARL1?

The P2N2907ARL1 has a maximum collector-emitter voltage rating (V_CEO) of −60 Vdc, verified per the onsemi datasheet under test condition I_C = −10 mA and I_B = 0. This rating defines the absolute upper limit for reverse bias applied between collector and emitter before breakdown occurs, and must not be exceeded in design.

Is the P2N2907ARL1 compatible with lead-free soldering processes?

Yes, the P2N2907ARL1 is a Pb-free device compliant with RoHS Directive 2011/65/EU. Its TO-92 package is qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C, as confirmed in onsemi's Soldering and Mounting Techniques Reference Manual.

What is the typical DC current gain (h_FE) of the P2N2907ARL1 at 150 mA collector current?

At I_C = −150 mA and V_CE = −10 Vdc, the P2N2907ARL1 exhibits a minimum h_FE of 100 and a maximum of 300 per the onsemi datasheet. This wide gain range reflects process variation and must be accounted for in bias network design to ensure consistent operation across production lots.

Does the P2N2907ARL1 have the same pinout as the PN2907A?

Yes, the P2N2907ARL1 uses the identical TO-92 pinout as the PN2907A: Pin 1 = Collector, Pin 2 = Base, Pin 3 = Emitter. Both parts share identical mechanical drawings (Style 17), electrical specifications, and thermal characteristics, enabling direct substitution in existing layouts.

What is the thermal resistance from junction to ambient (R_JA) for the P2N2907ARL1 in free-air conditions?

The P2N2907ARL1 has a thermal resistance from junction to ambient (R_JA) of 200°C/W when mounted in still air on a standard PCB per JEDEC JESD51-2. This value assumes no added heatsinking and defines the temperature rise per watt of dissipated power - critical for reliability in continuous conduction mode.
