Product details

Overview

SMBTA06E6327HTSA1 from Infineon Technologies is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio frequency amplification and switching applications. It features V_CEO = 80 V, I_C = 500 mA continuous, h_FE ≥ 100 at I_C = 10 mA, V_CE(sat) ≤ 0.25 V at I_C = 100 mA / I_B = 10 mA, and operates up to T_j = 150 °C. It is used in low-voltage power supply control circuits and signal buffering stages.

For engineers reviewing the SMBTA06E6327HTSA1 datasheet, SMBTA06E6327HTSA1 pinout, SMBTA06E6327HTSA1 application, or SMBTA06E6327HTSA1 equivalent, key selection criteria include DC current gain linearity across I_C, thermal resistance R_thJS ≤ 215 K/W, saturation voltage under defined drive conditions, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This NPN BJT operates in linear or saturated mode depending on base drive and collector load. Its h_FE remains stable from −50 °C to +125 °C, with typical f_T = 100 MHz at I_C = 20 mA / V_CE = 5 V, supporting mid-frequency signal amplification. C_cb = 7 pF at V_CB = 10 V enables predictable high-frequency response.

The device uses a planar epitaxial structure with emitter ballasting for current uniformity. Its SOT-23 package provides defined thermal path to PCB copper, enabling P_tot = 330 mW at T_S ≤ 79 °C. Complementary PNP SMBTA56 is specified for push-pull configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before breakdown under open-base condition
I_C (continuous)	500 mA - Continuous collector current rating defining steady-state power handling
h_FE @ I_C=10 mA	≥100 - Minimum DC current gain ensuring reliable base drive sizing for switching
V_CE(sat)	≤0.25 V @ I_C=100 mA/I_B=10 mA - Low saturation voltage minimizing conduction loss in switch mode
f_T	100 MHz @ I_C=20 mA/V_CE=5 V - Transition frequency indicating usable bandwidth for AF amplification
R_thJS	≤215 K/W - Junction-to-soldering-point thermal resistance guiding PCB copper area design

Pinout & Package

Supplied in SOT-23 (TO-236AB) plastic surface-mount package with gull-wing leads. Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector (viewed from top, marking side up, notch left).

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input terminal	Receives forward-biased current to enable conduction between collector and emitter
2 (Emitter)	Current return path	Common reference node for biasing; connected to ground or low-side rail in common-emitter configuration
3 (Collector)	Output current terminal	Delivers amplified or switched current to load; requires proper voltage headroom relative to emitter

Key Features

Feature	Design Value
Low V_CE(sat)	≤0.25 V ensures <125 mW conduction loss at 100 mA, reducing thermal load in compact layouts
High h_FE consistency	h_FE ≥100 at 10 mA and ≥100 at 100 mA supports stable gain across operating range
Thermal robustness	T_j = 150 °C max and R_thJS ≤215 K/W allow operation in sealed enclosures without forced cooling

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBTA06-7-F	Same die, identical electrical specs; differs only in tape-and-reel packaging (7-inch reel vs. 180 mm)	No functional difference; suitable for same PCB footprints and thermal designs	Select based on assembly line feeder compatibility and volume order requirements
BC846B,215	Lower V_CEO = 65 V, higher h_FE = 200–450, but not AEC-Q101 qualified	Limited to non-automotive consumer/industrial use; unsuitable for automotive modules requiring stress validation	Choose only where automotive qualification is unnecessary and higher gain is prioritized

Compared with MMBTA06-7-F, SMBTA06E6327HTSA1 offers identical performance in a different reel format; versus BC846B,215, it trades higher voltage rating and automotive qualification for lower h_FE spread, making it preferable for safety-critical or high-V_CE applications.

FAQ

Is SMBTA06E6327HTSA1 RoHS compliant?

Yes, SMBTA06E6327HTSA1 is Pb-free and fully compliant with EU RoHS Directive 2011/65/EU. The SOT-23 package contains no lead-based solder or plating, and all materials meet restricted substance thresholds per Annex II.

What is the maximum allowable base current for continuous operation?

The absolute maximum continuous base current is I_B = 100 mA, as specified in the Absolute Maximum Ratings table. Exceeding this risks metallization failure or bond wire degradation, even if V_BE remains within limits.

Can SMBTA06E6327HTSA1 replace BC547 in existing designs?

Not directly: BC547 has V_CEO = 45 V and I_C = 100 mA, while SMBTA06E6327HTSA1 offers 80 V and 500 mA. Substitution requires verifying layout clearance, thermal margin, and drive circuit compatibility-especially base resistor recalculations due to differing h_FE curves.

Does this part support pulsed operation beyond its DC ratings?

Yes, pulse operation is permitted up to I_CM = 1 A for t_p ≤ 10 ms with duty cycle D ≤ 2%, provided peak power does not exceed P_tot(max) limits shown in Figure 5 of the datasheet and thermal mass prevents junction overheating.
