Product details

Overview

BC847AE6327HTSA1 from Infineon Technologies is an NPN general-purpose bipolar junction transistor rated for 45 V V_CEO, 100 mA I_C, and 300 mW P_D in PG-SOT23 package, used for low-power switching and amplification in signal conditioning stages of industrial sensor interfaces and portable power management circuits.

For engineers reviewing the BC847AE6327HTSA1 datasheet, BC847AE6327HTSA1 pinout, BC847AE6327HTSA1 application, or BC847AE6327HTSA1 equivalent, key selection criteria include DC current gain (h_FE = 110–220 at I_C = 2 mA), low saturation voltage (V_CE(sat) ≤ 0.6 V @ I_C/I_B = 10 mA/0.5 mA), and thermal resistance (R_thJA = 375 K/W).

Technical Context

This transistor operates in active or saturation mode with a maximum collector-emitter breakdown voltage of 45 V and a continuous collector current limit of 100 mA. Its DC current gain is specified across two test conditions: h_FE = 110–220 at I_C = 2 mA, V_CE = 5 V and h_FE = 200–450 at I_C = 10 mA, V_CE = 5 V.

It features a complementary PNP counterpart (BC857A) and shares the same PG-SOT23 footprint as BC846–BC848 series. The device is qualified per AEC-Q101 for stress-tested reliability in automotive ambient temperature ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum allowable collector-emitter voltage before breakdown under open-base condition.
I_C	100 mA - Continuous collector current rating defining safe linear or switching operation limits.
P_D	300 mW - Maximum power dissipation at T_A = 25 °C, derating linearly above 25 °C.
h_FE (min–max)	110–220 @ I_C = 2 mA, V_CE = 5 V - Ensures predictable small-signal amplification gain in bias-stable configurations.
V_CE(sat)	≤ 0.6 V @ I_C/I_B = 10 mA/0.5 mA - Low saturation voltage minimizes conduction loss in digital switch applications.
R_thJA	375 K/W - Junction-to-ambient thermal resistance determines required PCB copper area for thermal management.

Pinout & Package

BC847AE6327HTSA1 is housed in PG-SOT23 (JEDEC TO-236AB), a surface-mount plastic package with 3 leads and standard lead pitch of 0.95 mm. Thermal pad is not present; mounting relies on solder joint thermal conduction.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-side reference; defines current return path in common-emitter configuration.
2 (Base)	Control input terminal	Receives bias current to regulate collector current; requires current-limiting resistor in discrete driver designs.
3 (Collector)	Current source terminal	Delivers switched or amplified output current; connected to load or next-stage input in amplifier topologies.

Key Features

Feature	Design Value
High h_FE consistency	110–220 range at 2 mA ensures stable bias point across production lots without trim resistors.
Low V_CE(sat)	≤ 0.6 V enables efficient on-state performance in 3.3 V logic-level switching applications.
AEC-Q101 qualified	Qualified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114.
PG-SOT23 footprint	Standardized 3-pin SMT package allows drop-in replacement with BC846/BC847/BC848 family parts.

Applications

Use Scenario: Driving LED backlight segments and tactile feedback indicators in HVAC control panels.

IC Role / Device Role / Timing Role: Low-side switch controlled by 3.3 V microcontroller GPIO pins.

Use Value: V_CE(sat) ≤ 0.6 V limits power loss to <15 mW per channel at 20 mA load current.

Portable Battery Management

Consumer Audio Input Stage

Use Scenario: Enabling/disabling charging path MOSFET gate drivers in USB-C power banks.

IC Role / Device Role / Timing Role: Digital switch isolating enable signals between battery protection IC and external FETs.

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
BC847B (Infineon)	Higher h_FE range: 200–450 @ I_C = 2 mA, otherwise identical ratings and package.	Suitable where tighter gain tolerance is needed for precision bias networks.	Select BC847B when circuit gain stability demands >200 minimum h_FE.
MMBT3904LT1G (ON Semiconductor)	Same V_CEO (40 V), I_C (200 mA), but h_FE = 100–300 @ I_C = 10 mA; slightly higher P_D (350 mW).	Preferred in higher-current switching where 200 mA headroom improves margin.	Choose MMBT3904LT1G if design requires >100 mA peak collector current or higher thermal margin.

Compared with BC847B and MMBT3904LT1G, BC847AE6327HTSA1 offers balanced h_FE consistency and AEC-Q101 qualification, making it optimal for cost-sensitive automotive and industrial signal-path roles where moderate gain and proven reliability are prioritized over extreme current or gain extremes.

FAQ

Is BC847AE6327HTSA1 pin-compatible with BC847B?

Yes - both share identical PG-SOT23 pinout (Emitter-Base-Collector on pins 1–2–3) and mechanical dimensions. Electrical differences are limited to h_FE binning; no layout change is required for substitution in existing designs.

What is the maximum operating junction temperature for BC847AE6327HTSA1?

The absolute maximum junction temperature is 150 °C. Derating begins at 25 °C ambient, with R_thJA = 375 K/W; at 70 °C ambient, maximum continuous power drops to ~160 mW to maintain T_J ≤ 150 °C.

Does BC847AE6327HTSA1 support pulsed operation beyond 100 mA?

Yes - pulse current up to 200 mA is allowed for t_p ≤ 10 ms and duty cycle ≤ 10%, provided average power remains within 300 mW and T_J does not exceed 150 °C. Refer to Infineon's "Pulse Ratings" graph in the official datasheet.

Can BC847AE6327HTSA1 be used in linear amplifier configurations?

Yes - its h_FE stability and low noise characteristics support Class-A and Class-AB small-signal amplification. Use emitter degeneration and proper biasing to maintain linearity; avoid operation near V_CEO or I_C limits to prevent distortion or thermal runaway.
