Product details
Overview
PN2907ARLRAG from onsemi is a PNP silicon general-purpose transistor in TO-92 package, rated for –60 V VCEO, –600 mA IC, and 625 mW PD at TA = 25°C, commonly used in low-power switching and linear amplification circuits such as LED drivers and signal inversion stages.
For engineers reviewing the PN2907ARLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCEO/IC ratings, hFE range across operating currents, thermal resistance (RθJA = 200°C/W), saturation voltage behavior, and TO-92 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
The PN2907ARLRAG operates as a medium-current PNP bipolar junction transistor with DC current gain (hFE) ranging from 75 to 300 depending on collector current - 75 min at IC = –0.1 mA, 100 min at IC = –1.0 mA and –10 mA, and 50 min at IC = –500 mA. Its fT of 200 MHz supports high-speed switching applications up to tens of MHz.
It exhibits VCE(sat) ≤ –0.4 V at IC = –150 mA/IB = –15 mA and ≤ –1.6 V at IC = –500 mA/IB = –50 mA, with VBE(sat) ≤ –1.3 V and ≤ –2.6 V under same conditions. Input and output capacitances are Cibo ≤ 30 pF and Cobo ≤ 8.0 pF, enabling predictable RC time constants in switching nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | –60 Vdc - maximum safe collector-emitter reverse bias before breakdown in common-emitter configuration |
| IC | –600 mAdc - continuous collector current limit defining usable load drive capability |
| PD @ TA = 25°C | 625 mW - power dissipation limit at ambient temperature, derated by 5.0 mW/°C above 25°C |
| hFE | 75–300 - DC current gain range supporting stable biasing from microamp to 500 mA loads |
| fT | 200 MHz - unity-gain frequency confirming suitability for fast-switching and RF pre-driver roles |
| RθJA | 200°C/W - junction-to-ambient thermal resistance indicating need for heatsinking above ~300 mW dissipation |
| ton/toff | 45 ns / 100 ns - turn-on and turn-off times measured under standardized test conditions for timing-critical logic interfaces |
Pinout & Package
PN2907ARLRAG is housed in a TO-92 (Case 29, Style 1) plastic package with 3 leads, designed for through-hole mounting and manual prototyping. Lead spacing matches standard 0.1" pitch breadboards and PCB footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Current exit node in PNP operation; connects to higher potential rail in switch configurations |
| 2 | Base | Control terminal requiring negative base current relative to emitter to enable conduction |
| 3 | Collector | Current entry node; typically tied to load and supply rail in common-emitter switching topologies |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | –60 V enables use in 48 V industrial control rails and automotive battery-sensed circuits without derating |
| Wide hFE range | 75–300 supports robust bias design across production lots and temperature extremes (–55°C to +150°C) |
| Low VCE(sat) | ≤ –0.4 V at 150 mA reduces conduction loss and self-heating in relay drivers and power logic inverters |
| TO-92 mechanical standardization | Pin-compatible with legacy PN2907A variants and widely supported by automated assembly equipment |
| Specified switching speed | 45 ns ton and 100 ns toff allow reliable operation in 5–10 MHz digital clock buffering and pulse shaping |
Applications
| LED Driver Circuit | Signal Level Inversion |
|---|---|
Use Scenario: Driving 20–100 mA indicator LEDs from 3.3 V or 5 V microcontroller GPIO pins with active-low logic control. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter mode, sinking current from LED anode to ground when base is pulled low. Use Value: Low VCE(sat) minimizes voltage drop across PN2907ARLRAG, preserving forward voltage margin for red/green/blue LEDs. |
Use Scenario: Converting TTL/CMOS logic-high signals to active-low outputs for reset lines, enable controls, or interrupt generation. IC Role / Device Role / Timing Role: Digital inverter stage where input applied to base via current-limiting resistor, output taken from collector. Use Value: Verified ton/toff ensures sub-100 ns propagation delay, maintaining timing integrity in synchronous logic interfaces. |
| Relay Coil Driver | Linear Amplifier Stage |
Use Scenario: Switching 12 V or 24 V electromagnetic relays with coil currents up to 500 mA in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Saturated PNP switch controlling relay coil current path between supply rail and ground return. Use Value: –600 mA IC rating and –60 V VCEO accommodate back-EMF spikes during relay de-energization without snubber diodes. |
Use Scenario: Low-noise audio preamplifier or sensor signal conditioning stage operating at IC = –100 µA to –1 mA. IC Role / Device Role / Timing Role: Common-emitter amplifier biased in linear region with fixed emitter resistor and collector load. Use Value: Specified noise figure (NF ≈ 4–6 dB at 1 kHz) and stable hFE support consistent small-signal gain in analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA92 | Higher VCEO (–300 V), lower IC (–500 mA), TO-92 package, hFE 25–200 | Better suited for high-voltage flyback or CRT deflection circuits; less optimal for high-current switching | Select MPSA92 only when >–100 V blocking is required; PN2907ARLRAG preferred for cost-sensitive 60 V systems |
| BC557 | Lower VCEO (–45 V), same IC (–100 mA), TO-92, hFE 110–800, faster fT (≥300 MHz) | Optimized for low-power signal amplification and high-frequency switching below 100 mA | Choose BC557 for low-current, high-speed designs; PN2907ARLRAG remains appropriate for 150–500 mA loads at 60 V |
Compared with MPSA92 and BC557, PN2907ARLRAG delivers balanced performance across voltage, current, and gain - making it the preferred choice for mid-range PNP switching where –60 V/–600 mA capability and proven thermal reliability in TO-92 are critical.

FAQ
What is the maximum collector current rating for PN2907ARLRAG?
The PN2907ARLRAG has a maximum continuous collector current (IC) rating of –600 mAdc at TA = 25°C. Derating applies above this temperature - consult the thermal resistance RθJA = 200°C/W and PD derating curve to determine safe operating current at elevated ambient temperatures. The PN2907ARLRAG must not exceed this limit in sustained operation to avoid thermal runaway or parametric shift.
Is PN2907ARLRAG pin-compatible with the original PN2907A?
Yes, PN2907ARLRAG uses the identical TO-92 package (Case 29, Style 1) with pin 1 = Emitter, pin 2 = Base, pin 3 = Collector - matching the mechanical and electrical pinout of the legacy PN2907A. No PCB layout changes are needed when substituting PN2907ARLRAG into existing designs qualified for PN2907A, provided tape-and-reel handling requirements are accommodated.
What is the typical DC current gain (hFE) of PN2907ARLRAG at 150 mA collector current?
At IC = –150 mAdc and VCE = –10 Vdc, the PN2907ARLRAG exhibits a minimum hFE of 100 and a typical value near 200. This gain level ensures stable saturation in switching applications while allowing sufficient margin for temperature variation and process spread across manufacturing lots of the PN2907ARLRAG.
Does PN2907ARLRAG support operation at elevated junction temperatures?
Yes, PN2907ARLRAG is rated for junction temperatures from –55°C to +150°C. Its electrical characteristics - including leakage current (ICBO ≤ –10 µAdc at 150°C) and hFE stability - are specified across this full range. Designers must ensure thermal design limits RθJA and power dissipation to keep TJ within this envelope during operation of the PN2907ARLRAG.
What is the storage time (ts) specification for PN2907ARLRAG in switching applications?
The PN2907ARLRAG has a maximum storage time (ts) of 80 ns under standard test conditions: VCC = –30 Vdc, IC = –150 mAdc, IB1 = IB2 = 15 mAdc, and TJ = 25°C. This parameter directly impacts turn-off delay in saturated switching; designers should account for ts when calculating minimum off-time in PWM or digital logic interfacing using the PN2907ARLRAG.
