Nexperia USA Inc. 2PA1576S,115

Overview

2PA1576S from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for V_CEO = −50 V, I_C = −150 mA, and h_FE = 270–560 at V_CE = −6 V / I_C = −1 A. It delivers low collector capacitance (2.5 pF typ.) and V_CE(sat) ≤ −500 mV at I_C = −50 mA / I_B = −5 mA, supporting compact signal switching in space-constrained consumer and industrial PCBs.

For engineers reviewing the 2PA1576S datasheet, 2PA1576S pinout, 2PA1576S application, or 2PA1576S equivalent, key selection criteria include verified PNP polarity, SC-70 thermal resistance (625 K/W on FR4), absolute maximum ratings (e.g., T_j ≤ 150 °C), and confirmed NPN complement (2PC4081S) for push-pull design.

Technical Context

This discrete PNP transistor operates in linear amplification and saturated switching modes with defined DC current gain across I_C = −1 mA to −100 mA and V_CE = −6 V. Its f_T of 100 MHz at V_CE = −12 V / I_C = −2 mA supports audio-frequency and low-speed digital signal handling.

The device adheres to IEC 60134 Absolute Maximum Ratings, with V_CBO = −60 V, V_EBO = −6 V, and P_tot = 200 mW at T_amb ≤ 25 °C on standard FR4. Thermal resistance R_th(j-a) = 625 K/W reflects its SOT323 footprint limitations under single-sided copper conditions.

Key Specifications

Pinout & Package

FAQ

Is the 2PA1576S automotive-qualified?

No. Per Nexperia's 2023 data sheet revision history, this part is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is not warranted for use in safety-critical or life-support systems. Automotive alternatives require suffix -Q (e.g., 2PA1576Q) and separate qualification documentation.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA, but continuous operation must respect the total power dissipation limit of 200 mW at T_amb ≤ 25 °C. With V_BE ≈ −0.75 V, sustained I_B > −260 µA would exceed P_tot if V_CE and I_C are non-zero; practical designs limit I_B to ≤ −5 mA for reliable saturation at I_C = −50 mA.

Can the 2PA1576S replace the 2N3906 in existing designs?

Only with verification. While both are PNP transistors, the 2PA1576S has higher h_FE (270–560 vs. 100–300), lower V_CE(sat) (≤ −500 mV vs. ≤ −400 mV), and smaller SOT323 package versus TO-92. Layout, thermal, and gain-dependent bias stability must be rechecked; direct substitution may cause overdrive or thermal mismatch.

Does the 2PA1576S have a documented NPN complement?

Yes. Nexperia explicitly lists the 2PC4081S as the NPN complement in Section 1 of the data sheet. Both share identical SOT323 packaging, voltage/current ratings (V_CEO = 50 V, I_C = 150 mA), and thermal characteristics, enabling matched pair usage in push-pull, differential, or complementary amplifier topologies.
