Product details
Overview
2SA1576ART1G from onsemi is a PNP general-purpose amplifier transistor in SC-70 (SOT-323) package, rated for V(BR)CEO = 50 V, IC = 100 mA continuous, hFE = 180–390 at 2 mA/6 V, and PD = 200 mW - used in low-power audio preamplifier stages and signal switching circuits in portable electronics.
For engineers reviewing the 2SA1576ART1G datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed hFE range at low IC, VCE(sat) ≤ 0.5 V at 100 mA/10 mA drive, ESD-safe SC-70 packaging, and Pb-free compliance per J-STD-020 Level 1.
Technical Context
This PNP bipolar junction transistor operates in linear amplification and active switching modes with specified breakdown voltages (V(BR)CBO = 60 V, V(BR)EBO = 7.0 V) and cutoff leakage limits (ICBO ≤ 0.1 µA, ICEO ≤ 0.1 µA at 10 V). Its thermal rating supports operation up to TJ = 150°C with derated power above 25°C ambient.
The device uses epitaxial planar construction with base-emitter junction optimized for stable DC current gain across production lots. It is not designed for RF or high-speed switching; maximum fT is not characterized in the provided documentation and therefore omitted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CEO | 50 V - Maximum collector-emitter voltage before avalanche breakdown under open-base condition; defines safe operating voltage headroom in amplifier bias networks. |
| IC (cont.) | 100 mA - Continuous collector current limit; sets upper bound for quiescent bias and small-signal output swing capability. |
| hFE | 180–390 - DC current gain at VCE = 6 V, IC = 2 mA; enables predictable base drive sizing for Class-A amplifiers and switch saturation. |
| VCE(sat) | ≤ 0.5 V - Collector-emitter saturation voltage at IC = 100 mA, IB = 10 mA; ensures low conduction loss in saturated-switch applications. |
| PD | 200 mW - Maximum power dissipation at TA = 25°C; determines thermal design margin for PCB copper area and ambient temperature derating. |
| TJ max | 150°C - Absolute maximum junction temperature; constrains thermal interface design and long-term reliability in sealed enclosures. |
Pinout & Package
Package: SC-70 (SOT-323), 3-pin surface-mount plastic case, moisture sensitivity level 1, Pb-free compliant (indicated by "G" suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control electrode; requires current-limited drive to achieve target IC; polarity-sensitive for PNP operation (reverse-biased relative to emitter). |
| 2 | Emitter | Current source terminal; connected to higher potential in PNP circuits; serves as reference node for bias network return path. |
| 3 | Collector | Output current sink terminal; connected to load and supply rail; voltage swing limited by V(BR)CEO and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free SC-70 package | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 MSL Level 1 - eliminates post-reflow moisture sensitivity concerns and supports lead-free assembly. |
| Guaranteed hFE range | 180–390 at 2 mA/6 V - enables consistent gain matching across production batches without binning or trimming in discrete amplifier designs. |
| Low VCE(sat) | ≤ 0.5 V at 100 mA/10 mA - reduces power loss and self-heating during switching, improving efficiency in battery-powered logic-level translators. |
| High V(BR)CBO | 60 V - provides robustness against transient voltage spikes in automotive body electronics and industrial sensor interfaces. |
Applications
| Audio Preamp Stage | Level-Shifting Switch |
|---|---|
Use Scenario: Low-voltage single-supply audio front-end in portable media players and headset amplifiers. IC Role / Device Role / Timing Role: PNP small-signal amplifier configured in common-emitter topology for voltage gain and impedance transformation. Use Value: Stable hFE and low noise enable clean gain of weak microphone signals without requiring feedback compensation. |
Use Scenario: Converting 3.3 V logic outputs to drive 5 V or 12 V loads in microcontroller-based control modules. IC Role / Device Role / Timing Role: Saturated PNP switch translating logic-high (low-side grounded) to active-low output referenced to higher rail. Use Value: VCE(sat) ≤ 0.5 V minimizes voltage drop and heat generation during sustained ON-state operation. |
| Sensor Signal Conditioning | LED Current Sink Driver |
Use Scenario: Amplifying millivolt-level outputs from thermistors and bridge sensors in HVAC and industrial monitoring systems. IC Role / Device Role / Timing Role: Linear-mode PNP amplifier in transimpedance or differential pair configuration for analog signal scaling. Use Value: Tight V(BR)CEO = 50 V and ICBO ≤ 0.1 µA ensure accuracy and stability over temperature and time. |
Use Scenario: Driving indicator LEDs in space-constrained IoT nodes and medical handheld devices. IC Role / Device Role / Timing Role: Constant-current sink using emitter resistor biasing, leveraging precise hFE for predictable LED brightness control. Use Value: SC-70 footprint allows integration into dense PCB layouts while maintaining thermal safety at 200 mW dissipation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose amplifier transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SA1015KT146 | Higher V(BR)CEO = 50 V (same), but hFE = 70–400 at 10 mA/6 V; larger SOT-23 package (PD = 250 mW). | Broader hFE spread increases gain variation risk in precision bias networks; larger footprint may require layout revision. | Select when higher power margin or legacy SOT-23 compatibility is required; verify hFE binning for critical gain stability. |
| MMBT2907ALT1G | Same SC-70 package, but V(BR)CEO = 60 V, hFE = 100–300 at 10 mA/1 V; lower VCE(sat) = 0.4 V typical at 150 mA/15 mA. | Higher voltage rating suits wider supply ranges; reduced saturation voltage improves efficiency in high-duty-cycle switching. | Prefer for new designs needing extended voltage headroom or lower conduction loss; confirm gain tolerance fits system linearity requirements. |
Compared with 2SA1576ART1G, the 2SA1015KT146 offers higher power handling but looser hFE control, while the MMBT2907ALT1G delivers superior voltage margin and saturation performance at the cost of reduced minimum gain - both require validation of bias point stability in the target circuit.

FAQ
What is the maximum operating temperature for the 2SA1576ART1G?
The 2SA1576ART1G has a maximum junction temperature (TJ) of 150°C and a storage temperature range of −55°C to +150°C. Derating of power dissipation begins above 25°C ambient, with linear reduction to zero at 150°C case temperature. Thermal design must account for PCB copper area and airflow to maintain TJ within this limit during continuous operation of the 2SA1576ART1G.
Is the 2SA1576ART1G pin-compatible with other SC-70 PNP transistors?
The 2SA1576ART1G uses Style 7 pinout: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector. This matches standard SC-70 PNP orientation per onsemi's mechanical drawings. However, pin compatibility does not guarantee electrical equivalence - always verify V(BR)CEO, hFE, and VCE(sat) before substituting other SC-70 PNP parts for the 2SA1576ART1G.
Does the 2SA1576ART1G support lead-free reflow soldering?
Yes, the 2SA1576ART1G is Pb-free and qualified for lead-free reflow per J-STD-020. Its moisture sensitivity level is 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly. The "G" suffix confirms compliance with RoHS Directive 2011/65/EU and JEDEC standards for the 2SA1576ART1G.
What is the typical DC current gain (hFE) of the 2SA1576ART1G at low collector current?
The 2SA1576ART1G is specified with hFE = 180–390 at VCE = 6.0 V and IC = 2.0 mA. This range reflects production lot variation and ensures predictable base drive requirements in low-current amplifier and bias circuits. Gain decreases at higher IC and lower VCE, so design margins should be based on the minimum value for the 2SA1576ART1G.
Can the 2SA1576ART1G be used in switching applications?
Yes, the 2SA1576ART1G is suitable for low-frequency switching (≤100 kHz) due to its guaranteed VCE(sat) ≤ 0.5 V at IC = 100 mA and IB = 10 mA. It is not characterized for switching speed (tf, tr) or high-frequency operation. For fast switching, consult onsemi's dedicated switching transistor portfolio instead of relying on the 2SA1576ART1G.
