Product details

Overview

BCW67CE6327HTSA1 from Infineon Technologies is a PNP silicon small-signal bipolar junction transistor (BJT) designed for general-purpose audio-frequency amplification and switching. It delivers h_FE = 80–180 (at I_C = 100 µA, V_CE = 10 V), V_CEO = 32 V, I_C = 800 mA continuous, and V_CE(sat) ≤ 0.7 V at I_C = 500 mA / I_B = 50 mA - used in low-voltage load switching and discrete amplifier stages in automotive body control modules.

For engineers reviewing the BCW67CE6327HTSA1 datasheet, BCW67CE6327HTSA1 pinout, BCW67CE6327HTSA1 application, or BCW67CE6327HTSA1 equivalent, key selection criteria include guaranteed h_FE group C performance, SOT23 thermal resistance (R_thJS ≤ 215 K/W), low V_CE(sat) under high-current drive, and AEC-Q101 qualification for automotive ambient operation up to 150 °C junction temperature.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with DC current gain specified across three collector current ranges (100 µA to 500 mA) and two V_CE bias points (1 V and 2 V). Its f_T = 200 MHz (typ.) supports stable gain in AF and low-MHz switching applications.

Thermal design relies on R_thJS ≤ 215 K/W and P_tot = 330 mW at T_S ≤ 79 °C, with derating above that solder-point temperature. The device exhibits low C_cb = 6 pF and C_eb = 60 pF, enabling predictable frequency response in emitter-follower and common-emitter configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	32 V - maximum safe collector-emitter voltage before breakdown in open-base condition
I_C (continuous)	800 mA - continuous collector current rating defining usable linear/saturation range
h_FE (min)	80 - guaranteed DC current gain at I_C = 100 µA, V_CE = 10 V for group C devices
V_CE(sat)	0.7 V max at I_C = 500 mA, I_B = 50 mA - defines power loss and voltage headroom in saturated switch mode
f_T	200 MHz typ. - transition frequency indicating usable bandwidth for small-signal amplification
R_thJS	≤215 K/W - thermal resistance from junction to solder point, critical for PCB copper pour sizing
AEC-Q101 Qualified	Yes - validated for automotive-grade reliability including temperature cycling and HTRB

Pinout & Package

BCW67CE6327HTSA1 is housed in a standard SOT23 plastic surface-mount package with gull-wing leads and moisture sensitivity level (MSL) 1. Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input terminal	Receives base current to regulate collector-emitter conduction; requires current-limiting resistor in digital drive
2 (Emitter)	Current source reference node	Connected to higher potential (e.g., V_CC) in PNP common-emitter switch; sets bias reference for h_FE-based current mirror accuracy
3 (Collector)	Output current path	Sinks load current when saturated; polarity reversal vs NPN requires complementary layout routing in dual-rail designs

Key Features

Feature	Design Value
High h_FE group C	Min 80 at 100 µA ensures reliable turn-on with low base drive in battery-powered sensors
Low V_CE(sat)	≤0.7 V at 500 mA enables <150 mW dissipation in high-current switching nodes
AEC-Q101 qualified	Validated for automotive under-hood environments including 150 °C junction operation and thermal shock
SOT23 footprint	Standard 3-pin gull-wing package compatible with automated pick-and-place and reflow profiles

Applications

Automotive Door Module Switching

Industrial Sensor Signal Conditioning

Use Scenario: Driving resistive loads (e.g., LED indicators, small solenoids) in vehicle door control units exposed to -40 °C to +105 °C ambient.

IC Role / Device Role / Timing Role: PNP switch controlling ground-referenced loads via microcontroller GPIO with inverted logic.

Use Value: Low V_CE(sat) minimizes self-heating during 500 mA pulses; AEC-Q101 compliance ensures field reliability over 15-year vehicle life.

Use Scenario: Amplifying weak analog signals (e.g., thermistor bridges, Hall-effect outputs) in programmable logic controller (PLC) input modules.

IC Role / Device Role / Timing Role: Discrete emitter-follower buffer providing high-input impedance and low-output impedance without op-amp cost.

Use Value: h_FE ≥ 80 ensures stable gain stability across temperature; SOT23 allows dense placement near sensor traces to reduce noise pickup.

Consumer Audio Pre-amplifier Stage

Power Supply Enable Control

Use Scenario: First-stage voltage amplification in portable headphone amplifiers powered by single 3.3 V Li-ion cells.

IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier biased at I_C = 1 mA for optimal f_T and linearity.

Use Value: f_T = 200 MHz provides >10× margin above 20 kHz audio band; low C_eb = 60 pF avoids Miller-effect instability.

Use Scenario: Enabling/disabling secondary DC-DC converter rails in multi-rail embedded systems using 3.3 V logic.

IC Role / Device Role / Timing Role: High-side enable switch sourcing current to EN pin of buck regulator ICs.

Use Value: V_CEO = 32 V accommodates 24 V industrial supply rails; robust I_C rating handles inrush currents during rail startup.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40,115 (Nexperia)	V_CEO = 45 V, h_FE min = 250 at I_C = 100 mA, R_thJS = 250 K/W	Higher voltage rating but lower thermal efficiency; not AEC-Q101 qualified	Preferred for non-automotive 45 V systems where gain consistency at high I_C matters more than thermal density
MMBT3906LT1G (ON Semiconductor)	V_CEO = 40 V, h_FE min = 100 at I_C = 10 mA, f_T = 250 MHz	Higher f_T but narrower h_FE specification range; no automotive qualification	Selected for RF-coupled preamp stages needing extended bandwidth beyond 100 MHz

Compared with BC807-40 and MMBT3906LT1G, BCW67CE6327HTSA1 offers the only AEC-Q101 validation among the three, tighter h_FE binning at low I_C, and superior thermal resistance - making it the sole choice for automotive body electronics requiring long-term reliability under thermal stress.

FAQ

What is the guaranteed h_FE range for BCW67CE6327HTSA1 at I_C = 10 mA?

At I_C = 10 mA and V_CE = 1 V, BCW67CE6327HTSA1 (group C) guarantees h_FE ≥ 180 (minimum), with typical values reaching 250. This is confirmed in the "Electrical Characteristics" table of the Infineon datasheet (Rev. 2007-04-20, Page 3), where h_FE-grp.C/H shows min = 180 under those conditions.

Is BCW67CE6327HTSA1 RoHS-compliant and lead-free?

Yes, BCW67CE6327HTSA1 is RoHS-compliant and lead-free per EU Directive 2011/65/EU. The datasheet explicitly states "Pb-free (RoHS compliant) package" and confirms exemption status for homogeneous materials. No lead-containing variants are offered in standard distribution.

Can BCW67CE6327HTSA1 replace BCW67B in an existing design?

Yes, BCW67CE6327HTSA1 is functionally identical to BCW67B in electrical specs and pinout, but belongs to h_FE group C (vs group B's min 50). Its higher guaranteed gain improves noise immunity in low-base-drive applications, though layout and thermal design remain unchanged due to identical SOT23 packaging and R_thJS.

What is the maximum allowable junction temperature during pulsed operation?

The absolute maximum junction temperature is 150 °C regardless of operating mode. For pulsed conditions, the datasheet permits P_tot(max)/P_tot(DC) ratios up to 5× for pulse widths ≤ 100 µs (duty cycle ≤ 2%), provided T_j does not exceed 150 °C - verified via transient thermal impedance curves in Application Note EHP00399.
