Nexperia USA Inc. 2PB709BSL,215

Overview

2PB709BSL from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 (TO-236AB) package, rated for −50 V V_CEO, −200 mA I_C, and DC current gain (h_FE) of 290–460 (Group S), qualified to AEC-Q101 for automotive use, and commonly deployed in low-power switching circuits such as LED drivers and signal-level amplification stages.

For engineers reviewing the 2PB709BSL datasheet, 2PB709BSL pinout, 2PB709BSL application, or 2PB709BSL equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated automotive-grade alternatives - all grounded in Nexperia's official product data sheet Rev. 1 (28 June 2010).

Technical Context

This discrete PNP BJT operates with open-base collector-emitter breakdown voltage of −50 V and supports continuous collector current up to −200 mA at T_amb ≤ 25 °C. Its h_FE group S (290–460) ensures predictable current amplification under V_CE = −10 V and I_C = −2 mA conditions, enabling stable biasing in linear and saturated switching modes.

The device exhibits V_CE(sat) ≤ −250 mV at I_C = −100 mA / I_B = −10 mA, and f_T ≥ 100 MHz at V_CE = −6 V / I_C = −10 mA / f = 100 MHz, confirming suitability for medium-speed digital switching and audio-frequency amplification where low saturation loss and moderate bandwidth are required.

FAQ

What is the maximum allowable junction temperature for 2PB709BSL?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in Table 6 of the Nexperia datasheet. Operation beyond this limit risks permanent degradation of h_FE and increased leakage currents. Derating begins at T_amb > 25 °C using R_th(j-a) = 500 K/W, reducing P_tot by 0.5 mW/°C above ambient.

Is 2PB709BSL suitable for linear amplifier applications?

Yes - its h_FE stability across −55 °C to +150 °C (Fig 6), low V_CE(sat), and f_T ≥ 100 MHz support Class-A and Class-AB audio preamplifier stages and DC-coupled sensor signal conditioning, provided biasing avoids saturation and power dissipation remains within 250 mW derated limits.

How does the marking code 'MP*' identify 2PB709BSL on the device?

The top-side marking 'MP*' (where * indicates manufacturing location: p = Hong Kong, t = Malaysia, W = China) is the standardized Nexperia identification for 2PB709BSL in SOT23 package, distinct from 2PB709BRL's 'MN*' marking - enabling visual verification during assembly and inspection.

Can 2PB709BSL replace BC807-40 in existing designs?

No - while both are SOT23 PNP transistors, BC807-40 has V_CEO = −45 V and h_FE = 250–630, differing in breakdown margin and gain distribution. 2PB709BSL's −50 V rating and tighter 290–460 h_FE group S offer improved transient robustness but require validation of base drive and thermal margins before substitution.
