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, this page delivers verified electrical parameters, SC-70 terminal mapping, thermal resistance (625 K/W), collector capacitance (2.5 pF), and functional alternatives for discrete PNP switching design validation.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with defined absolute maximum ratings: −60 V V_CBO, −6 V V_EBO, and −200 mA I_CM. Its transition frequency f_T is 100 MHz at −12 V V_CE and −2 mA I_C, supporting RF-capable small-signal amplification up to VHF band.

Thermal performance is characterized by R_th(j-a) = 625 K/W on FR4 PCB with single-sided copper, and leakage currents are tightly specified: ICBO ≤ −100 nA at 25 °C and ≤ −5 µA at 150 °C, ensuring stable operation across industrial temperature range (−65 °C to 150 °C).

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 configurations.
I_C	−150 mA - Continuous collector current rating; sets load drive capability in linear or saturated switching modes.
h_FE	180–390 - DC current gain at −6 V V_CE, −1 A I_C; determines base drive requirement for predictable saturation.
V_CE(sat)	≤ −500 mV - Collector-emitter saturation voltage at −50 mA I_C, −5 mA I_B; impacts conduction loss in switching applications.
C_c	2.5 pF (typ.) - Collector capacitance at −12 V V_CB, 1 MHz; limits high-frequency response and affects stability in amplifier stages.
f_T	100 MHz - Transition frequency under −12 V V_CE, −2 mA I_C; enables use in VHF pre-amplifiers and oscillator bias networks.
R_th(j-a)	625 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; informs derating curves for ambient temperatures above 25 °C.

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 size, optimized for high-density routing and reflow soldering.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on device.
2	Emitter (E)	Current source terminal in PNP configuration; typically connected to higher potential rail in common-emitter switches.
3	Collector (C)	Current sink terminal; carries load current to ground or lower-potential node when device is active or saturated.

Key Features

Feature	Design Value
Low collector capacitance	2.5 pF typical - minimizes Miller effect and improves high-frequency gain stability in amplifier designs.
High DC current gain	h_FE = 180–390 - reduces required base drive current, easing interface with low-output-current logic or microcontroller GPIO.
Compact SOT323 footprint	2.0 mm × 1.25 mm body - enables placement in ultra-dense layouts where board area is constrained, such as wearables or sensor modules.
Industrial temperature range	−65 °C to +150 °C operating/storage - supports deployment in extended-environment industrial controls and power management subsystems.

Applications

LED Driver Circuits

Level-Shifting Interfaces

Use Scenario: Driving indicator LEDs from 3.3 V or 5 V MCU outputs in portable instrumentation.

IC Role / Device Role / Timing Role: PNP switch controlling LED anode connection to supply rail; emitter tied to V_CC, collector to LED cathode.

Use Value: Low V_CE(sat) (≤ −500 mV) ensures minimal voltage drop, preserving LED forward voltage margin and brightness consistency.

Use Scenario: Translating logic signals between 5 V and 3.3 V domains in mixed-voltage digital systems.

IC Role / Device Role / Timing Role: Active-low level shifter using PNP emitter-follower configuration with pull-up resistors.

Use Value: High h_FE and low leakage (< −100 nA ICBO) maintain clean logic thresholds and prevent false triggering during idle states.

Low-Power Sensor Biasing

Power Rail Enable Switches

Use Scenario: Providing stable bias current to analog sensor front-ends (e.g., thermistors, photodiodes) in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: Constant-current source configured in common-emitter mode with emitter resistor feedback.

Use Value: Tight h_FE spread (180–390) and low C_c enable precise, low-noise biasing without oscillation or drift over temperature.

Use Scenario: Enabling/disabling auxiliary power rails (e.g., 3.3 V LDO input) in modular embedded systems with sequenced startup.

IC Role / Device Role / Timing Role: High-side switch controlling V_IN to downstream regulators; base driven by enable signal through current-limiting resistor.

Use Value: −50 V V_CEO and −150 mA I_C support robust rail control across varied input voltages while maintaining low quiescent current.

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	Same SOT323 package; h_FE = 250–630 (higher gain spread); V_CEO = −45 V (5 V lower)	Suitable for higher-gain amplification but less margin in 50 V rail applications	Select when tighter base drive control is needed and V_CEO derating is acceptable
MMBT3906LT1G	Same −40 V V_CEO, −200 mA I_C; h_FE = 100–300; slightly higher C_c (4 pF)	Better current handling but reduced HF performance and lower breakdown margin	Prefer for higher-current switching where 100 MHz f_T is not required

Compared with BC807-40,115 and MMBT3906LT1G, the 2PA1576R offers superior V_CEO margin (−50 V), lower capacitance (2.5 pF), and balanced h_FE for predictable base drive-making it optimal for 50 V-tolerant, space-constrained, and moderate-frequency switching roles.

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-grade screening, and guaranteed operation under automotive temperature or reliability stress profiles. For automotive use, select variants marked with "-Q" suffix.

What is the recommended PCB footprint for reflow soldering?

The official reflow footprint for SOT323 specifies solder land dimensions of 0.6 mm × 0.5 mm (3×), solder resist opening of 0.55 mm × 0.55 mm (3×), and center-to-center pitch of 1.325 mm. These dimensions ensure reliable solder joint formation and mechanical stability during thermal cycling.

Can the 2PA1576R replace the 2PA1576 without modification?

Yes. The "R" suffix denotes a revised version compliant with Nexperia's updated identity guidelines and non-automotive status, but with identical electrical specifications, pinout, package, and marking compatibility. No schematic or layout changes are required for drop-in replacement.

How does thermal resistance change with PCB copper area?

R_th(j-a) = 625 K/W is measured on a standard FR4 board with single-sided 1 oz copper and minimal pad area. Increasing copper pour area or adding thermal vias can reduce this value significantly-Nexperia's application notes show up to 30 % improvement with 25 mm² copper extension per pad-but exact values require thermal simulation or empirical measurement.
