Product details

Overview

2PA1576Q-Q from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for −50 V V_CEO, −150 mA I_C, and 120–270 h_FE at −1 mA collector current; it delivers low collector capacitance (2.5 pF typ.) and is AEC-Q101 qualified for automotive signal switching and amplification.

For engineers reviewing the 2PA1576Q-Q datasheet, 2PA1576Q-Q pinout, 2PA1576Q-Q application, or 2PA1576Q-Q equivalent, this page provides verified electrical parameters, validated SC-70 terminal mapping, automotive-grade reliability context, and direct alternatives with documented functional alignment and packaging compatibility.

Technical Context

This PNP BJT operates in linear amplification and saturated switching modes, with V_CE(sat) ≤ −500 mV at I_C = −50 mA / I_B = −5 mA and f_T = 100 MHz at V_CE = −12 V / I_C = −2 mA - confirming suitability for low-power RF-coupled and digital logic interface functions up to mid-VHF range.

Thermal resistance R_th(j-a) is 625 K/W on FR4 PCB (single-sided copper), and absolute maximum ratings include T_j = 150 °C, V_CB0 = −60 V, and I_CM = −200 mA peak - defining safe operating area boundaries for transient load handling and thermal design margining.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V: Maximum allowable collector-emitter voltage with base open; defines breakdown safety margin in switching applications.
I_C	−150 mA continuous: Rated DC collector current; sets upper limit for steady-state load drive capability.
h_FE	120–270 at V_CE = −6 V, I_C = −1 mA: Confirmed DC current gain range; enables predictable base drive sizing for bias networks.
C_c	2.5 pF typ. at V_CB = −12 V: Low collector capacitance supports stable high-frequency response and minimal Miller effect in amplifier stages.
f_T	100 MHz: Transition frequency confirms usable bandwidth for small-signal amplification up to ~10 MHz with gain >1.
P_tot	200 mW at T_amb ≤ 25 °C: Total power dissipation limit; constrains thermal layout on standard FR4 PCBs.

Pinout & Package

SOT323 (SC-70) plastic surface-mounted package: 3-lead, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body; optimized for space-constrained automotive control modules and portable electronics.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control electrode for forward-active and saturation operation; requires current-limited drive to ensure h_FE-based gain stability.
2	Emitter (E)	Current source terminal in PNP configuration; connected to higher potential rail in common-emitter switching circuits.
3	Collector (C)	Output current sink terminal; carries full load current in saturated switch mode and sets output impedance in active-region amplifiers.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated stress-test compliance for automotive under-hood and infotainment systems requiring extended temperature and reliability assurance.
Low V_CE(sat)	≤ −500 mV at I_C = −50 mA / I_B = −5 mA: Minimizes conduction loss and self-heating during high-duty-cycle switching.
Low C_c	2.5 pF typical: Reduces capacitive loading on driving stages and improves stability in feedback amplifier configurations.
Small footprint	SOT323 package (2.0 × 1.25 mm): Enables high-density placement in compact ECUs, sensor interfaces, and LED driver PCBs.

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
2PA1776Q-Q	Same SOT323 package; h_FE = 180–390 at −1 mA; V_CEO = −50 V; C_c = 2.2 pF	Higher minimum h_FE improves base drive margin in low-current bias networks	Select when tighter h_FE consistency is required for production calibration.
BC807-40W	SOT323 package; V_CEO = −45 V; I_C = −500 mA; h_FE = 250–630 at −100 mA	Higher current rating but wider h_FE spread and non-AEC-Q101 qualification	Acceptable for non-automotive industrial use where cost sensitivity outweighs qualification requirements.

Compared with 2PA1576Q-Q, 2PA1776Q-Q offers enhanced h_FE consistency for precision biasing, while BC807-40W trades automotive qualification for higher current capacity - making the original optimal for AEC-Q101–mandated, low-power, space-constrained switching.

FAQ

Is the 2PA1576Q-Q pin-compatible with its NPN complement 2PC4081Q-Q?

Yes - both devices share identical SOT323 (SC-70) package dimensions and pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This enables symmetrical PCB layout for complementary transistor pairs in push-pull or differential amplifier designs without footprint redesign.

What is the maximum allowable ambient temperature for continuous operation at full rated current?

At I_C = −150 mA, the device reaches thermal limit at T_amb ≈ 75 °C on standard FR4 PCB (R_th(j-a) = 625 K/W). Derating is required above this point; full-rated operation is only guaranteed below 25 °C ambient unless heatsinking or forced airflow is applied.

Does the 2PA1576Q-Q support reflow soldering per JEDEC J-STD-020?

Yes - Nexperia specifies full compliance with JEDEC J-STD-020D for lead-free reflow. The recommended profile includes peak temperature of 260 °C for ≤ 30 seconds, with ramp rates and soak zones aligned to SOT323 thermal mass and FR4 board constraints.

How does the −100 nA I_CBO at 25 °C impact leakage-sensitive applications?

With collector-base leakage ≤ −100 nA at 25 °C and ≤ −5 µA at 150 °C, the device maintains low standby current in always-on automotive modules - enabling microamp-level sleep-mode current budgets without external leakage compensation circuitry.
