Product details

Overview

BC847CE6327HTSA1 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 (SOT-23) package; used as a low-power switch or amplifier in signal routing, LED biasing, and logic-level translation circuits.

For engineers reviewing the BC847CE6327HTSA1 datasheet, BC847CE6327HTSA1 pinout, BC847CE6327HTSA1 application, or BC847CE6327HTSA1 equivalent, key selection criteria include DC current gain (h_FE = 420–800 at I_C = 2 mA), low saturation voltage (V_CE(sat) ≤ 0.6 V @ I_C/I_B = 10 mA/0.5 mA), and SOT-23 thermal performance in space-constrained PCB layouts.

Technical Context

This transistor operates in active or saturation mode with guaranteed h_FE range of 420–800 at 2 mA collector current and 5 V V_CE; base-emitter voltage is specified at 0.7 V typical under forward bias. It supports switching speeds with t_ON ≤ 5 ns and t_OFF ≤ 30 ns at I_C = 10 mA.

Designed for surface-mount assembly, it complies with AEC-Q101 stress testing for automotive-grade reliability and features Pb-free termination per RoHS Directive 2011/65/EU. Junction-to-ambient thermal resistance is 350 K/W in standard FR-4 layout.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom in 24 V rail switching.
I_C	100 mA - continuous collector current rating; supports LED drivers and small-signal relay coils.
P_D	300 mW - power dissipation limit at T_A = 25 °C; requires derating above 25 °C ambient.
h_FE	420–800 @ I_C = 2 mA - DC current gain range ensures predictable base drive sizing across production lots.
V_CE(sat)	≤ 0.6 V @ I_C/I_B = 10 mA/0.5 mA - low saturation voltage minimizes conduction loss in switching applications.
f_T	300 MHz - transition frequency enables stable amplification up to VHF band edge in RF detector stages.

Pinout & Package

Package: PG-SOT23 (JEDEC TO-236AB), 3-pin surface-mount plastic case with gull-wing leads; footprint compatible with IPC-7351B SOIC-3 land pattern.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-side return path; determines common-emitter reference point.
2 (Base)	Control input	Receives current-limited drive signal; requires series resistor to limit I_B per h_FE and I_C target.
3 (Collector)	Current source terminal	Connects to load and supply rail; carries full switched current with minimal V_CE(sat) drop.

Key Features

Feature	Design Value
High h_FE binning	Guaranteed 420–800 range enables consistent base drive design without margin overdesign.
AEC-Q101 qualified	Validated for automotive electronics including body control modules and sensor interfaces.
Low V_CE(sat)	Reduces power loss and self-heating in high-duty-cycle switching (e.g., PWM dimming).
SOT-23 thermal resistance	350 K/W allows operation up to 125 °C junction temperature with minimal copper pour.

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,315 (Nexperia)	Same h_FE bin (200–450), lower max V_CEO (45 V same), but no AEC-Q101 certification.	Not qualified for automotive environments; suitable for industrial/commercial PCBs only.	Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs.
MMBT3904LT1G (ON Semiconductor)	Lower h_FE (100–300), higher V_CE(sat) (0.2–0.3 V @ 10 mA), identical SOT-23 package.	Less gain margin for low-base-drive designs; may require larger base resistors.	Choose where tighter V_CE(sat) tolerance is prioritized over h_FE consistency.

Compared with BC847B and MMBT3904LT1G, BC847CE6327HTSA1 provides the widest h_FE range and automotive qualification-critical for designs requiring robust base-current predictability and extended temperature reliability.

FAQ

What is the maximum junction temperature for BC847CE6327HTSA1?

The absolute maximum junction temperature is 150 °C. Operation beyond this limit risks permanent degradation of h_FE and increased leakage current. Derating curves in the official Infineon datasheet specify allowable power dissipation versus ambient temperature, with full 300 mW rating valid only at T_A ≤ 25 °C.

Is BC847CE6327HTSA1 pin-compatible with BC847C variants from other manufacturers?

Yes-BC847CE6327HTSA1 uses standard SOT-23 pinout (E-B-C), matching industry-standard BC847C devices. However, h_FE binning (420–800) and AEC-Q101 qualification are unique to this Infineon variant; electrical behavior under transient conditions may differ from non-automotive equivalents.

Can BC847CE6327HTSA1 be used in linear amplifier configurations?

Yes-it is characterized for active-mode operation with guaranteed h_FE and f_T = 300 MHz, supporting stable small-signal amplification up to ~100 MHz. Bias networks must ensure V_CE > 1 V and I_C within 1–10 mA for optimal linearity and gain flatness.

Does BC847CE6327HTSA1 support lead-free reflow soldering?

Yes-its PG-SOT23 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 10 seconds. The device meets RoHS Directive 2011/65/EU and has no exemptions applied to its termination finish.
