Product details

Overview

2PA1015GR,126 from Nexperia (formerly Philips Semiconductors) is a PNP general-purpose bipolar junction transistor in TO-92 (SOT54) package, rated for −50 V V_CEO, −150 mA I_C, and 500 mW P_tot, used in low-voltage switching and linear amplification circuits such as signal buffering in consumer audio preamps and power management enable logic.

For engineers reviewing the 2PA1015GR,126 datasheet, 2PA1015GR,126 pinout, 2PA1015GR,126 application, or 2PA1015GR,126 equivalent, key selection criteria include its guaranteed h_FE range of 200–400 at −2 mA, −6 V, saturation voltage ≤−300 mV at −100 mA/−10 mA drive, and thermal resistance of 250 K/W on FR4 PCB - all critical for thermally constrained discrete gain stages and level-shifting switches.

Technical Context

This PNP BJT operates with emitter-follower or common-emitter topology in DC-coupled or capacitively coupled configurations. Its f_T of 80 MHz supports audio-frequency amplification and low-speed digital switching up to ~10 MHz, while C_c = 4–7 pF ensures minimal Miller effect in high-gain stages.

Designed for through-hole mounting on standard FR4 boards, it relies on ambient convection cooling with no heatsink; R_th(j-a) = 250 K/W limits continuous dissipation to 500 mW only at T_amb ≤25 °C, requiring derating above that temperature per the linear derating curve defined in the datasheet.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V: Maximum collector-emitter blocking voltage in open-base configuration; defines safe operating voltage in switching applications.
I_C (DC)	−150 mA: Continuous collector current limit; sets maximum load drive capability in saturated switch mode.
h_FE @ −2 mA	200–400: DC current gain range at low bias; enables predictable base drive sizing for amplification or switching.
V_CE(sat)	≤−300 mV @ −100 mA/−10 mA: Low saturation voltage reduces conduction loss and self-heating in on-state operation.
P_tot	500 mW @ T_amb ≤25 °C: Total power dissipation limit on FR4 board; requires thermal derating above ambient temperature.
f_T	80 MHz: Transition frequency at −1 mA, −10 V; confirms usable bandwidth for audio and low-speed digital signals.
R_th(j-a)	250 K/W: Junction-to-ambient thermal resistance on standard FR4; determines temperature rise under steady-state bias.

Pinout & Package

2PA1015GR,126 is housed in a plastic through-hole TO-92 package (JEDEC TO-92, Philips SOT54, EIAJ SC-43A), with 3 leads and standardized lead spacing (e = 2.54 mm). The package is optimized for manual soldering and wave-solder compatibility on double-sided PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Current-controlled input node; requires series resistor to limit I_B and ensure proper h_FE-based gain or saturation.
2	Collector	Main current sink terminal; connected to higher potential (e.g., V_CC) in PNP switch configurations.
3	Emitter	Current source terminal; typically tied to supply rail in common-emitter or grounded-emitter switching topologies.

Key Features

Feature	Design Value
Guaranteed h_FE range	200–400 at −2 mA/−6 V ensures consistent base drive requirements across production lots.
Low V_CE(sat)	≤−300 mV at −100 mA/−10 mA minimizes voltage drop and power loss in saturated switching.
Controlled noise figure	10 dB at −200 µA/−5 V/1 kHz enables use in low-noise preamplifier front-ends without added filtering.
High f_T	80 MHz supports stable gain up to mid-audio frequencies and fast edge response in pulse applications.
TO-92 mechanical standardization	Compatible with legacy through-hole assembly tooling and hand-soldering workflows.

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
BC807-40,115	SMD SOT-23 package; h_FE = 250–630 at −100 mA; V_CEO = −45 V; P_tot = 310 mW.	Not suitable for through-hole prototyping or wave-soldered legacy designs; better for space-constrained PCBs.	Select when board area is limited and reflow assembly is available.
2N3906RLRPG	TO-92 package; h_FE = 100–300 at −10 mA; V_CEO = −40 V; V_CE(sat) = −400 mV @ −10 mA.	Lower gain and higher saturation voltage reduce drive efficiency in high-current switching.	Select only if lower cost outweighs performance trade-offs in non-critical bias networks.

Compared with BC807-40,115 and 2N3906RLRPG, the 2PA1015GR,126 offers superior h_FE consistency at low currents and lower V_CE(sat), making it preferable for precision gain-setting and low-loss switching where through-hole mounting is required.

FAQ

What is the maximum continuous collector current for 2PA1015GR,126?

The 2PA1015GR,126 has a maximum DC collector current (I_C) rating of −150 mA, specified under steady-state conditions with ambient temperature ≤25 °C and proper PCB thermal management. Exceeding this value risks thermal runaway or permanent degradation of h_FE and V_CE(sat) performance in the 2PA1015GR,126.

Does 2PA1015GR,126 have a guaranteed minimum h_FE at low collector current?

Yes, the 2PA1015GR,126 guarantees h_FE ≥200 at V_CE = −6 V and I_C = −2 mA, ensuring predictable base drive design for small-signal amplification and bias networks. This specification is explicitly confirmed in the Philips/Nexperia datasheet and distinguishes the 2PA1015GR,126 from lower-gain variants like the 2PA1015Y.

Can 2PA1015GR,126 be used as a direct replacement for 2N3906 in existing designs?

No - while both are PNP TO-92 transistors, the 2PA1015GR,126 has higher h_FE (200–400 vs. 100–300), lower V_CE(sat) (≤−300 mV vs. −400 mV), and higher V_CEO (−50 V vs. −40 V). These differences may alter bias point stability or switching speed; redesign verification is required before substituting 2PA1015GR,126 for 2N3906.

What is the thermal resistance junction-to-ambient for 2PA1015GR,126?

The 2PA1015GR,126 has a thermal resistance R_th(j-a) of 250 K/W when mounted on a standard FR4 printed-circuit board per datasheet note 1. This value assumes no copper pour or heatsinking; actual thermal performance depends on PCB layout, copper area, and airflow - critical for sustained operation near its 500 mW P_tot limit in the 2PA1015GR,126.

Is there an NPN complement to 2PA1015GR,126?

Yes, the NPN complement to 2PA1015GR,126 is the 2PC1815, which shares identical package (TO-92/SOT54), voltage ratings (V_CEO = +50 V), current capability (+150 mA), and thermal characteristics. This pairing enables complementary-symmetry amplifier stages and push-pull output drivers using the 2PA1015GR,126 and 2PC1815 together.
