Product details

Overview

BCW67A E6327 from Infineon Technologies is a PNP silicon general-purpose audio-frequency bipolar junction transistor in SOT23 package, rated for V_CEO = 32 V, I_C = 800 mA, and P_tot = 330 mW at T_S ≤ 79°C, with h_FE = 35–100 (group A/F) at I_C = 100 µA and V_CE = 10 V, used in low-voltage switching and linear amplification stages of consumer audio and power management circuits.

For engineers reviewing the BCW67A E6327 datasheet, BCW67A E6327 pinout, BCW67A E6327 application, or BCW67A E6327 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 SOT23 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 (A/F: h_FE = 35–100), collector-emitter breakdown voltage of 32 V, and emitter-base breakdown voltage of 5 V. Its thermal resistance R_thJS ≤ 215 K/W enables stable operation up to T_j = 150°C under controlled board-level heatsinking.

The device exhibits low V_CE(sat) (0.3–0.7 V) across I_C = 100–500 mA, enabling efficient switching in low-dropout load control, while its f_T = 200 MHz supports audio-band amplification and moderate-speed digital signal conditioning without external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	32 V - Maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration
I_C	800 mA - Continuous DC collector current rating at T_S ≤ 79°C, defining maximum linear/saturation load handling
h_FE (A/F group)	35–100 - DC current gain range at I_C = 100 µA/V_CE = 10 V, critical for bias stability in amplifier designs
V_CE(sat)	0.3–0.7 V - Collector-emitter voltage drop in saturation at I_C = 100–500 mA, directly impacting conduction loss
f_T	200 MHz - Transition frequency at I_C = 50 mA/V_CE = 5 V, indicating usable bandwidth for AF and low-speed switching
C_cb	6 pF - Collector-base junction capacitance at V_CB = 10 V, limiting high-frequency gain roll-off and Miller effect
R_thJS	≤215 K/W - Thermal resistance from junction to soldering point, governing temperature rise under steady-state power dissipation

Pinout & Package

BCW67A E6327 is housed in a standard SOT23 plastic surface-mount package with 3-pin configuration and gull-wing leads. The package outline complies with JEDEC TO-236AB, with body dimensions 2.9 mm × 1.3 mm × 1.0 mm and 0.95 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (Marked)	Base (B)	Control electrode; requires current-limited drive (I_B ≤ 100 mA) to achieve specified h_FE and V_CE(sat)
2	Emitter (E)	Current source terminal in PNP operation; connected to higher potential rail in typical switch/amplifier topologies
3	Collector (C)	Output current sink terminal; voltage swing limited by V_CEO = 32 V and thermal derating above T_S = 79°C

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive electronics per stress test requirements including HTOL, TC, and HAST, supporting under-hood and infotainment applications
Low V_CE(sat)	0.3 V typical at I_C = 100 mA/I_B = 10 mA, reducing power loss and heat generation in saturated-switch mode
High h_FE consistency	Group A/F guarantees h_FE ≥35 at I_C = 100 µA, enabling predictable biasing in discrete amplifier stages
RoHS-compliant SOT23	Pb-free termination and molding compound meet EU Directive 2011/65/EU, compatible with lead-free reflow profiles (peak 260°C)

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40,215 (Nexperia)	V_CEO = 45 V, h_FE = 250–630 (group 40), SOT23 package, same pinout	Higher gain and voltage rating; less suitable for low-V_CE optimization where BCW67A's 0.3 V V_CE(sat) is critical	Select when higher h_FE stability at I_C > 100 mA is required, but verify thermal margin due to higher P_tot derating
MMBT3906LT1G (ON Semiconductor)	V_CEO = 40 V, h_FE = 100–300, V_CE(sat) = 0.4 V @ I_C/I_B = 10/1 mA, SOT23	Optimized for low-current switching (I_C ≤ 200 mA); not rated for 500 mA continuous operation like BCW67A	Prefer for GPIO-driven logic-level switching; avoid in 500 mA load applications where BCW67A's robustness is validated

Compared with BC807-40 and MMBT3906LT1G, BCW67A E6327 offers superior thermal performance at high I_C (330 mW @ T_S ≤ 79°C vs. 300 mW typical), tighter V_CE(sat) control at 500 mA, and AEC-Q101 qualification-making it preferred for automotive and industrial switching where reliability under sustained load is mandatory.

FAQ

Is BCW67A E6327 pin-compatible with BCW66 series NPN transistors?

No. BCW67A is a PNP transistor with Base-Emitter-Collector pinout (1-2-3), while BCW66 is an NPN complementary type with identical SOT23 mechanical footprint but reversed polarity and opposite current flow direction. Direct substitution without circuit topology revision will cause functional failure.

What is the maximum allowable base current for continuous operation?

The absolute maximum DC base current is 100 mA, but for reliable long-term operation at I_C = 500 mA, design practice limits I_B to ≤50 mA to maintain V_CE(sat) ≤ 0.7 V and avoid thermal runaway. Pulse base current up to 200 mA is permitted only for t_p < 300 µs with duty cycle D < 2%.

Does BCW67A E6327 support lead-free reflow soldering?

Yes. BCW67A E6327 is RoHS-compliant with Pb-free terminations and qualifies for standard lead-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. The SOT23 package withstands JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) without baking.

How does AEC-Q101 qualification impact BCW67A E6327's use in non-automotive applications?

AEC-Q101 qualification certifies enhanced robustness against temperature cycling, humidity, and electrical stress-benefiting any high-reliability application. While not required for consumer gear, it provides measurable margin in industrial controls, medical peripherals, and outdoor equipment exposed to thermal shock or extended service life.
