Infineon Technologies BCW68FE6327HTSA1

Overview

BCW68FE6327HTSA1 from Infineon Technologies is a PNP silicon general-purpose audio-frequency bipolar junction transistor in SOT-23 package, rated for V_CEO = 45 V, I_C = 800 mA, and P_tot = 330 mW at T_S ≤ 79°C, with h_FE = 180 (min) at I_C = 10 mA and V_CE = 1 V, used in low-voltage switching and linear amplification stages of automotive body control modules and industrial sensor interface circuits.

For engineers reviewing the BCW68FE6327HTSA1 datasheet, BCW68FE6327HTSA1 pinout, BCW68FE6327HTSA1 application, or BCW68FE6327HTSA1 equivalent, key selection criteria include verified V_CE(sat) ≤ 0.7 V at I_C = 500 mA/I_B = 50 mA, f_T ≥ 200 MHz, C_cb = 6 pF, RoHS-compliant SOT-23 footprint, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with defined DC current gain groups (h_FE-grp.F), supports pulse operation up to 1 A peak collector current, and maintains stable gain across I_C = 100 µA to 500 mA at V_CE = 1–2 V. Its low V_CE(sat) and high h_FE enable efficient low-side switching and analog signal buffering in space-constrained PCB layouts.

Thermal resistance R_thJS ≤ 215 K/W ensures reliable junction temperature management under continuous 330 mW dissipation at soldering-point-limited board conditions. The device exhibits negligible leakage (I_CBO ≤ 0.02 µA at V_CB = 45 V, T_A = 25°C) and robust high-temperature performance up to T_j = 150°C.

FAQ

Is BCW68FE6327HTSA1 pin-compatible with BCW66 series NPN transistors?

No. BCW68FE6327HTSA1 is a PNP transistor with E-B-C pinout (1=E, 2=B, 3=C) in SOT-23, while BCW66-series NPN devices have C-B-E pinout (1=C, 2=B, 3=E). Direct substitution would reverse polarity and cause circuit failure. Use only complementary types like BCW66F for NPN pairing.

What is the maximum allowable PCB temperature (T_S) for full-rated power dissipation?

The datasheet specifies P_tot = 330 mW only when soldering-point temperature T_S ≤ 79°C. Exceeding this temperature linearly derates power capability; at T_S = 100°C, maximum dissipation drops to approximately 220 mW based on the published P_tot vs. T_S curve.

Does BCW68FE6327HTSA1 support pulsed operation beyond its DC current rating?

Yes. It supports peak collector current I_CM = 1 A under pulsed conditions (t_p < 300 µs, duty cycle D < 2%), enabling short-duration surge handling in motor drive or relay coil snubbing applications without thermal runaway.

How does the "F" suffix in BCW68F relate to h_FE performance?

The "F" denotes h_FE group F: minimum h_FE = 180 at I_C = 10 mA/V_CE = 1 V, rising to 350 at I_C = 500 mA. This grouping ensures predictable gain across operating current range, critical for consistent base drive sizing in production designs.
