Nexperia USA Inc. BCW61D,215

Overview

BCW61D,215 from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −32 V V_CEO, −100 mA I_C, and featuring h_FE = 380–630 at I_C = −2 mA, used in low-power switching and amplification circuits for consumer and industrial signal conditioning.

For engineers reviewing the BCW61D,215 datasheet, BCW61D,215 pinout, BCW61D,215 application, or BCW61D,215 equivalent, key selection criteria include its verified PNP polarity, SOT23 footprint compatibility, DC current gain range at multiple bias points, saturation voltage under defined drive conditions, and thermal resistance of 500 K/W on FR4 PCB.

Technical Context

The BCW61D,215 operates as a silicon PNP BJT with epitaxial planar construction, optimized for linear amplification and saturated switching in low-voltage analog and digital interface stages. Its f_T of 100 MHz supports audio-frequency and low-speed digital signal handling.

It exhibits low noise figure (2–6 dB at 1 kHz), tight h_FE distribution across grades (B/C/D), and stable cutoff currents (ICBO ≤ −20 nA at −32 V), enabling predictable biasing in temperature-sensitive amplifier designs.

FAQ

What is the maximum continuous collector current for BCW61D,215?

The BCW61D,215 has a maximum continuous collector current (I_C) of −100 mA at T_amb ≤ 25 °C, derated linearly above that temperature per its thermal resistance of 500 K/W. Peak pulsed current is rated at −200 mA with duty cycle ≤ 2%.

Is BCW61D,215 pin-compatible with BCW60 series?

Yes - BCW61D,215 (PNP) and BCW60 (NPN) share identical SOT23 pinout (1=base, 2=emitter, 3=collector), but polarity reversal means external circuitry must be adapted for complementary operation; they are not functional drop-in replacements.

What is the typical transition frequency (f_T) of BCW61D,215?

The BCW61D,215 has a guaranteed minimum f_T of 100 MHz at I_C = −10 mA, V_CE = −5 V, and f = 100 MHz, confirmed in the official Nexperia datasheet; this supports reliable operation in audio and low-speed digital signal paths.

Does BCW61D,215 require heatsinking in standard SOT23 mounting?

No - with P_tot = 250 mW and R_{th j-a} = 500 K/W on FR4, junction temperature rise remains below 125 K at full-rated power, well within its 150 °C max rating; no heatsink is needed for ≤100 mA DC operation at ambient ≤ 50 °C.
