Nexperia USA Inc. 2PB710ASL-QR

Overview

2PB710ASL-QR from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 package, rated for −50 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 170–340 at −150 mA. It operates as a low-voltage switching or linear amplification device in automotive control modules, power management stages, and sensor interface circuits.

For engineers reviewing the 2PB710ASL-QR datasheet, 2PB710ASL-QR pinout, 2PB710ASL-QR application, or 2PB710ASL-QR equivalent, key selection criteria include its AEC-Q101 qualification, −600 mV V_CEsat at −300 mA, thermal resistance of 500 K/W, and dual h_FE binning for consistent gain matching in parallel or feedback configurations.

Technical Context

This PNP BJT uses silicon planar epitaxial technology with optimized base doping and emitter geometry to deliver stable h_FE across temperature (−55 °C to 150 °C) and support pulsed operation up to 1 ms peak collector current (−1 A). Its −5 V V_EBO and −60 V V_CBO enable robust biasing in negative-rail signal conditioning paths.

The device is characterized under pulsed conditions (t_p ≤ 300 µs, duty δ ≤ 0.02) to minimize self-heating, ensuring specified h_FE and V_CEsat values reflect real-world switching performance. Its 140 MHz f_T supports audio-frequency amplification and moderate-speed digital switching up to ~10 MHz.

FAQ

What is the maximum allowable base current for continuous operation?

The datasheet specifies −200 mA as the peak base current (I_BM) for single pulses ≤1 ms. For continuous DC operation, base current must be limited to ensure junction temperature stays ≤150 °C. Using the 250 mW total power dissipation limit and typical V_BEsat of −1.5 V, maximum continuous I_B is approximately −160 mA - but practical designs use ≤−30 mA to maintain safe thermal margin and avoid gain degradation.

Can 2PB710ASL-QR replace an NPN transistor in the same circuit?

No - it cannot be used as a direct replacement for an NPN transistor due to reversed polarity: the 2PB710ASL-QR is PNP, requiring base voltage *lower* than emitter to turn on, whereas NPNs require base *higher* than emitter. Circuit topology (e.g., high-side vs low-side switching), bias network polarity, and signal inversion must all be redesigned to accommodate PNP operation.

Is the SOT23 footprint compatible with automated optical inspection (AOI)?

Yes - the SOT23 package has standardized 1.9 mm pitch and clearly defined solder pad geometry (per Fig. 2 and Fig. 3 in the datasheet), supporting reliable AOI detection of solder bridging, tombstoning, and insufficient paste volume. The "SD%" top marking provides sufficient contrast for post-reflow verification of part orientation and placement accuracy.

Does the −500 mW power rating apply at 125 °C ambient?

No - the 250 mW P_tot rating applies only at T_amb ≤ 25 °C on an FR4 PCB with single-sided copper. At 125 °C ambient, derating is required: using R_th(j-a) = 500 K/W, maximum allowable power drops to zero at T_j = 150 °C. At 125 °C ambient, safe continuous power is ~50 mW - confirmed by linear derating curves in Nexperia's thermal application notes.
