Product details

Overview

P2N2907AZL1 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 delivers −60 V V_CEO, −600 mA I_C, 200 MHz f_T, and operates across −55°C to +150°C junction temperature. It is commonly used in discrete amplifier stages, level shifters, and relay drivers in industrial control modules.

For engineers reviewing the P2N2907AZL1 datasheet, pinout, applications, or equivalent options, key selection criteria include its TO-92 package compatibility, verified −1.6 V V_CE(sat) at −500 mA, guaranteed h_FE ≥ 50 at high current, and Pb-free compliance per J-STD-609.

Technical Context

The P2N2907AZL1 is a medium-speed, low-voltage PNP BJT optimized for linear amplification and saturated-switching operation. Its f_T = 200 MHz supports audio-frequency gain and fast digital switching with t_on ≤ 50 ns and t_off ≤ 110 ns under defined bias conditions.

It features low leakage (I_CEO ≤ −10 nA), stable DC current gain across temperature (h_FE = 75–300 at I_C = −0.1 to −150 mA), and thermal resistance R_JA = 200°C/W enabling operation without heatsinking in ambient-limited PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum collector-emitter voltage before breakdown; enables use in −48 V telecom bias rails and industrial −24 V logic interfaces.
I_C	−600 mA - Continuous collector current rating; supports driving small relays, LEDs, or logic-level translators without external buffering.
f_T	200 MHz - Current-gain bandwidth product; ensures usable gain up to ~10–20 MHz in common-emitter amplifier configurations.
V_CE(sat)	−1.6 V @ I_C = −500 mA, I_B = −50 mA - Low saturation voltage reduces power loss in switching applications and improves efficiency in discrete H-bridge half-bridges.
h_FE	50–300 - DC current gain range across operating currents; allows predictable base drive design from microamp bias to 50 mA switching drive.
R_JA	200°C/W - Junction-to-ambient thermal resistance; permits 625 mW dissipation at 25°C ambient without forced airflow or heatsink.

Pinout & Package

Package: TO-92 (Case 29-11, Style 17), molded plastic with axial leads. Standard through-hole mounting; compatible with legacy wave-solder and hand-solder processes.

Pin/Terminal	Circuit Role	Design Meaning
1	Collector	Main current sink node; connects to load or supply rail in common-emitter or common-base topologies.
2	Base	Control terminal; requires current-limited drive (typically via series resistor) to bias transistor into active or saturation region.
3	Emitter	Current source node; tied to ground or positive rail depending on circuit configuration; defines reference for V_EB and V_CE.

Key Features

Feature	Design Value
Pb-free construction	Complies with J-STD-609 Class 3 moisture sensitivity and RoHS Directive 2011/65/EU; suitable for lead-free reflow profiles (peak 260°C).
Wide temperature range	Rated for −55°C to +150°C operation; validated for automotive under-hood and industrial motor-control environments.
Low leakage performance	I_CEO ≤ −10 nA at V_CE = −10 V; minimizes standby current in battery-powered sensor nodes and sleep-mode logic interfaces.
Fast switching capability	t_off ≤ 110 ns with I_C/I_B = 10; enables reliable operation in 1–5 MHz pulse-width modulation (PWM) circuits and digital signal inversion.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP BJT switching and amplification applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPSA92	Higher V_CEO (−300 V), lower f_T (50 MHz), same TO-92 package and pinout.	Better suited for high-voltage flyback snubbers and CRT deflection circuits; less optimal for >1 MHz switching.	Select MPSA92 only when >−100 V blocking is required; not recommended for high-frequency amplification due to reduced bandwidth.
PN2907A	Identical electrical specs and pinout; differs only in marking and packaging format (bulk vs. tape-and-reel); manufactured by same fab process.	No functional difference; interchangeable in all designs where tape-and-reel feed is not required.	PN2907A is functionally identical but supplied in bulk; P2N2907AZL1 offers tape-and-reel convenience for automated assembly.

Compared with MPSA92 and PN2907A, the P2N2907AZL1 provides optimal balance of speed (200 MHz f_T), saturation performance (−1.6 V V_CE(sat)), and Pb-free compliance-making it preferred for modern industrial control and audio signal-path designs requiring both reliability and manufacturability.

FAQ

What is the maximum continuous collector current rating for the P2N2907AZL1?

The P2N2907AZL1 has a maximum continuous collector current (I_C) rating of −600 mA at T_A = 25°C. Derating applies above 25°C at 5.0 mW/°C for free-air operation. This rating is confirmed in the "Maximum Ratings" table of the official onsemi datasheet (Rev. 4, March 2006), and supports reliable operation in relay driver and LED load-switching applications without thermal runaway.

Is the P2N2907AZL1 pin-compatible with the PN2907A?

Yes, the P2N2907AZL1 is pin-compatible with the PN2907A: both use TO-92 (Style 17) packaging with identical pin 1 (collector), pin 2 (base), pin 3 (emitter) assignment. The datasheet explicitly confirms identical marking diagrams and mechanical dimensions. No PCB layout changes are needed when substituting P2N2907AZL1 for PN2907A in tape-and-reel assembly lines.

Does the P2N2907AZL1 meet RoHS requirements?

Yes, the P2N2907AZL1 is Pb-free and RoHS-compliant per EU Directive 2011/65/EU. The "G" suffix variant (P2N2907AZL1G) explicitly denotes Pb-free packaging, and the base part number P2N2907AZL1 is documented in onsemi's Pb-Free Packaging Reference Manual as compliant with J-STD-609 Class 3 moisture sensitivity and lead-free reflow standards.

What is the typical DC current gain (h_FE) of the P2N2907AZL1 at −150 mA collector current?

The P2N2907AZL1 exhibits h_FE ≥ 100 at I_C = −150 mA, V_CE = −10 V, and T_A = 25°C, per the "Electrical Characteristics" table. This value is critical for designing base drive resistors in saturated-switch applications, ensuring sufficient gain margin to maintain V_CE(sat) ≤ −0.4 V under worst-case temperature and process variation.

Can the P2N2907AZL1 be used in linear amplifier configurations?

Yes, the P2N2907AZL1 is qualified for linear amplifier use, with verified noise figure < 6 dB at 1 kHz and stable h_FE across collector currents from −0.1 mA to −150 mA. Its f_T = 200 MHz supports bandwidth-limited audio and instrumentation amplifier stages, and the datasheet includes typical gain-vs-frequency and distortion curves confirming suitability for Class-A and AB biasing.
