Overview

BC214L_D26Z from Fairchild Semiconductor is a PNP general-purpose bipolar junction transistor (BJT) designed for amplification and switching in low-to-medium power analog and digital circuits, with V_CEO = −30 V, I_C = −500 mA continuous, h_FE = 100–400 at I_C = −10 µA to −100 mA, f_T = 200 MHz, and TO-92 package - used in audio preamplifiers, relay drivers, and level-shifting interfaces.

For engineers reviewing the BC214L_D26Z datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, guaranteed V_CEO/V_CBO ratings, DC current gain consistency across operating currents, thermal resistance (R_θJA = 200 °C/W), and TO-92 mechanical compatibility for through-hole prototyping and industrial control PCBs.

Technical Context

This PNP BJT operates with emitter as input, collector as output, and base as control terminal in common-emitter configuration. Its design supports linear amplification (V_CE = −5 V, I_C = −2 mA) and saturated switching (V_CE(sat) = −0.25 V at I_C = −10 mA / I_B = −0.5 mA), with noise figure NF = 2.0 dB at 15.7 kHz and output capacitance C_OB = 10 pF at V_CB = −10 V.

Thermal performance is defined by R_θJA = 200 °C/W and P_D = 625 mW at T_A = 25 °C, derating 5.0 mW/°C above ambient. Junction temperature range is −55 °C to +150 °C, enabling use in extended-temperature industrial environments without forced cooling.
