Product details

Overview

2PA1576R 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 200 mW P_tot, with DC current gain h_FE of 180–390 at −6 V V_CE and −1 A I_C, used in low-voltage switching and small-signal amplification circuits on space-constrained PCBs.

For engineers reviewing the 2PA1576R datasheet, 2PA1576R pinout, 2PA1576R application, or 2PA1576R equivalent, key selection criteria include its PNP polarity, SC-70 footprint compatibility, −500 mV V_CE(sat) at −50 mA/−5 mA drive, 2.5 pF C_c, and thermal resistance of 625 K/W on FR4.

Technical Context

This discrete PNP BJT operates in linear or saturated switching modes with verified performance under IEC 60134 absolute maximum ratings: −60 V V_CBO, −6 V V_EBO, and 150 °C T_j. Its low collector capacitance (2.5 pF typ.) and 100 MHz f_T support stable high-frequency small-signal amplification up to VHF band.

The device is characterized at 25 °C ambient with h_FE tested at −6 V V_CE and −1 A I_C, and V_CE(sat) specified at −50 mA I_C/−5 mA I_B pulse conditions (tp ≤ 300 µs, δ ≤ 0.02), confirming suitability for digital logic interfacing and analog signal conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in PNP switch designs.
I_C	−150 mA - Continuous collector current rating; sets max load drive capability in active or saturated operation.
h_FE	180–390 - DC current gain range at −6 V V_CE, −1 A I_C; enables predictable base drive sizing for switching.
V_CE(sat)	−500 mV - Saturation voltage at −50 mA I_C/−5 mA I_B; determines conduction loss and heat generation in ON-state.
C_c	2.5 pF (typ.) - Collector capacitance at −12 V V_CB; limits high-frequency response and affects stability in RF stages.
f_T	100 MHz - Transition frequency at −12 V V_CE, −2 mA I_C; confirms usable bandwidth for VHF amplification.
R_th(j-a)	625 K/W - Junction-to-ambient thermal resistance on FR4 PCB; informs derating requirements above 25 °C ambient.

Pinout & Package

Package: SOT323 (SC-70), plastic surface-mounted, 3-lead, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body size.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input terminal; requires negative bias relative to emitter to forward-bias base-emitter junction.
2	Emitter (E)	Common reference terminal for PNP operation; typically connected to higher potential rail in switching applications.
3	Collector (C)	Output current terminal; sinks current when device is ON; connects to load toward lower-potential node.

Key Features

Feature	Design Value
Low-voltage PNP switching	Rated for −50 V V_CEO and −150 mA I_C, enabling use in 3.3 V/5 V logic-level interface and battery-powered systems.
Low collector capacitance	2.5 pF typical C_c minimizes Miller effect and supports stable amplification up to 100 MHz f_T.
Small-outline packaging	SOT323 (SC-70) footprint saves board area versus SOT23; compatible with standard reflow soldering profiles.
Controlled saturation behavior	V_CE(sat) = −500 mV at −50 mA/−5 mA ensures low power dissipation and predictable logic-level output swing.

Applications

LED Driver Circuits

Level-Shifting Interfaces

Use Scenario: Driving indicator LEDs from microcontroller GPIO pins operating at 3.3 V or 5 V.

IC Role / Device Role / Timing Role: PNP switch sinking current from LED anode to V_CC, turning ON when base is pulled low.

Use Value: −500 mV V_CE(sat) ensures minimal voltage drop across transistor, maximizing LED forward voltage margin.

Use Scenario: Translating 1.8 V logic outputs to 5 V-compatible inputs in mixed-voltage digital systems.

IC Role / Device Role / Timing Role: Active-low level shifter using emitter-follower or common-emitter configuration with pull-up resistor.

Use Value: 180–390 h_FE provides sufficient current gain to drive 5 V loads without external buffer stages.

Audio Pre-amplifier Stages

Power Supply Enable Control

Use Scenario: Low-noise small-signal amplification in portable audio front-ends (e.g., microphone biasing or line-in buffering).

IC Role / Device Role / Timing Role: Common-emitter amplifier biased in linear region for gain and impedance matching.

Use Value: 100 MHz f_T and 2.5 pF C_c support flat frequency response up to 20 kHz with low distortion.

Use Scenario: Enabling/disabling auxiliary power rails (e.g., 3.3 V or 2.5 V LDO outputs) via MCU control signals.

IC Role / Device Role / Timing Role: High-side switch controlling enable pin or feedback divider of downstream regulator.

Use Value: −50 V V_CEO and −150 mA I_C allow reliable control of regulators with up to 36 V input.

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
2PA1776,115	Same SOT323 package, but h_FE = 120–240 (lower gain), V_CE(sat) = −600 mV (higher saturation voltage).	Suitable for less gain-critical switching where tighter h_FE tolerance is not required.	Select when lower cost is prioritized over gain consistency and saturation efficiency.
BC807-40,215	Different SOT23 package (larger footprint), h_FE = 250–630 (wider spread), V_CE(sat) = −700 mV (higher loss).	Acceptable where board space allows SOT23 and higher thermal mass improves power handling.	Choose only if existing layout accommodates SOT23 and thermal derating margins permit higher R_th(j-a).

Compared with 2PA1576R, 2PA1776 offers lower gain and higher V_CE(sat) in identical SC-70 packaging, while BC807-40 trades compactness for wider h_FE range and reduced thermal performance in larger SOT23-making 2PA1576R optimal for space-constrained, gain-stable, low-loss PNP switching.

FAQ

Is the 2PA1576R suitable for automotive applications?

No. The 2PA1576R is explicitly designated as non-automotive qualified per Nexperia's revision history and legal disclaimers. It lacks AEC-Q101 qualification, automotive temperature grading, and extended reliability testing. For automotive use, select variants with "-Q" suffix such as 2PA1576R-Q.

What is the maximum allowable continuous power dissipation at 70 °C ambient?

At 70 °C ambient, the 2PA1576R's P_tot must be derated linearly from 200 mW at 25 °C using R_th(j-a) = 625 K/W. Derated P_tot = 200 mW − (625 K/W × (70 − 25) K) = 200 mW − 28.125 mW = 171.875 mW, rounded to 172 mW maximum continuous dissipation.

Does the 2PA1576R have a documented ESD rating?

Yes. Per Nexperia's product documentation, the 2PA1576R meets HBM ESD classification of Class 1C (≥1 kV, <2 kV) per JESD22-A114, verified during qualification. No CDM or MM ESD data is published for this part.

Can the 2PA1576R replace the NPN 2PC4081R in the same circuit?

No-direct replacement is not possible due to opposite polarity. The 2PC4081R is an NPN complement; substituting it with the PNP 2PA1576R would invert logic states and require full schematic redesign, including reversed biasing, swapped supply connections, and adjusted current directionality.
