onsemi MPS2907ARLRP

Overview

MPS2907ARLRP 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. It delivers h_FE ≥ 100 at I_C = –1.0 mA and supports switching applications with t_on ≤ 45 ns and f_T = 200 MHz.

For engineers reviewing the MPS2907ARLRP datasheet, pinout, applications, or equivalent options, key selection criteria include its –60 V breakdown rating, TO-92 leaded package compatibility, low V_CE(sat) (–0.4 V at I_C = –150 mA), and verified performance across –55°C to +150°C junction temperature range.

Technical Context

The MPS2907ARLRP is a discrete PNP bipolar junction transistor optimized for linear amplification and medium-speed switching. Its design features a V_(BR)CEO of –60 V, V_BE(sat) of –1.3 V at I_C/I_B = 10, and C_obo = 8.0 pF - enabling stable operation in bias networks and low-noise preamp stages.

Thermal performance is defined by R_θJA = 200°C/W and R_θJC = 83.3°C/W, supporting reliable power dissipation up to 625 mW at ambient and 1.5 W at case. The device operates across –55°C to +150°C, with h_FE maintained ≥ 50 even at I_C = –500 mA.

FAQ

What is the maximum junction temperature rating for the MPS2907ARLRP?

The MPS2907ARLRP has a specified operating and storage junction temperature range of –55°C to +150°C. This wide range allows deployment in under-hood automotive environments and industrial enclosures without forced cooling. The device maintains electrical performance across this full span, with h_FE and V_CE(sat) characterized at both extremes in the official datasheet. Thermal derating begins above 25°C ambient at 5.0 mW/°C for ambient-limited operation.

Is the MPS2907ARLRP pin-compatible with the 2N3906?

No, the MPS2907ARLRP is not pin-compatible with the 2N3906. While both use TO-92 packages, the MPS2907ARLRP follows Style 1 pinout (1 = Emitter, 2 = Base, 3 = Collector), whereas the 2N3906 uses Style 2 (1 = Emitter, 2 = Collector, 3 = Base). Swapping them without PCB revision will result in incorrect biasing and circuit failure. Always verify pin assignment using the marking diagram and package outline in the MPS2907ARLRP datasheet.

What is the typical noise figure of the MPS2907ARLRP at 1 kHz?

The MPS2907ARLRP exhibits a typical noise figure of 2.0 dB at f = 1.0 kHz, V_CE = 10 Vdc, and I_C = –1.0 mA with R_s = 430 Ω. This value is confirmed in Figure 8 of the official datasheet and makes the MPS2907ARLRP suitable for low-noise preamplifier stages in sensor signal chains where SNR preservation is critical. Noise performance degrades slightly at lower collector currents, reaching 8.0 dB at I_C = –50 µA.

Can the MPS2907ARLRP be used in linear regulator pass transistor applications?

Yes, the MPS2907ARLRP can serve as a PNP pass transistor in linear regulators, particularly in low-dropout configurations where V_CE(sat) ≤ –0.4 V at I_C = –150 mA reduces dropout voltage. Its h_FE ≥ 100 at light loads ensures stable loop gain, and R_θJC = 83.3°C/W supports heatsink-assisted operation up to 1.5 W. However, due to its 625 mW ambient-rated dissipation, continuous >300 mA operation requires careful thermal design and is not recommended without case-mounting.

Does the MPS2907ARLRP meet RoHS and REACH compliance standards?

Yes, the MPS2907ARLRP is RoHS-compliant and meets REACH SVHC requirements per onsemi's published environmental documentation. The device uses lead-free terminations and halogen-free molding compound, consistent with onsemi's "Green" initiative. Compliance status is verified per JESD22-A112 and IEC 62321-2:2017 testing protocols, and material declarations are available via onsemi's Product Change Notification (PCN) portal for the MPS2907A family.
