Product details
Overview
BC847BL3E6327XTMA1 from Infineon Technologies is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver circuits. It features a minimum DC current gain (hFE) of 220 at IC = 2 mA, VCE = 5 V; VCEO = 45 V; VCE(sat) ≤ 250 mV at IC = 10 mA, IB = 0.5 mA; and is qualified to AEC-Q101 for automotive applications.
For engineers reviewing the BC847BL3E6327XTMA1 datasheet, BC847BL3E6327XTMA1 pinout, BC847BL3E6327XTMA1 application, or BC847BL3E6327XTMA1 equivalent, key selection criteria include its SOT23-3 package footprint, low-noise performance (F ≤ 4 dB at 1 kHz), high fT = 250 MHz, and guaranteed hFE group B/C grading for consistent amplification in signal conditioning paths.
Technical Context
This transistor operates as a linear amplifier or saturated switch in low-power analog and digital interface stages. Its design emphasizes stable hFE across temperature (150 °C max junction), low VCE(sat) for efficient switching, and low Ccb (0.95 pF typ.) and Ceb (9 pF typ.) to support wideband AF signal integrity up to 15 kHz.
The BC847BL3 variant uses the TSLP-3-1 package with lead-free (RoHS-compliant) terminations and meets AEC-Q101 stress testing requirements for automotive under-hood and infotainment subsystems. Its thermal resistance RthJS = 60 K/W enables reliable operation at Ptot = 250 mW when TS ≤ 135 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Supports rail voltages up to 36 V in automotive 12 V systems with safety margin. |
| hFE (min) | 220 @ IC = 2 mA - Ensures predictable small-signal gain stability in preamplifier bias networks. |
| VCE(sat) | ≤ 250 mV @ IC = 10 mA - Minimizes power loss and self-heating in switching applications. |
| fT | 250 MHz - Enables use in RF front-end buffers and fast digital logic interfaces up to ~100 MHz. |
| Ccb | 0.95 pF - Reduces Miller effect, improving high-frequency stability in common-emitter configurations. |
| Noise figure | ≤ 4 dB @ 1 kHz - Meets low-noise requirements for microphone preamps and sensor signal chains. |
| RthJS | 60 K/W - Allows direct PCB copper pour thermal coupling for sustained 250 mW dissipation at TS ≤ 135 °C. |
Pinout & Package
BC847BL3E6327XTMA1 is housed in the TSLP-3-1 surface-mount package (2.1 × 1.3 × 0.9 mm, 0.45 mm pitch), optimized for high-density automotive PCB layouts and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Connected to ground or low-impedance return path; defines reference for VBE and IC control. |
| 2 (Base) | Control input | Receives bias current to regulate collector current; requires series resistor for stable DC operating point. |
| 3 (Collector) | Current source terminal | Drives load toward positive supply; voltage swing limited by VCEO = 45 V rating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per ISO 10605. |
| Low VCE(sat) | 250 mV max ensures <1% voltage drop across transistor in saturated switching mode at 10 mA. |
| High hFE consistency | Group B/C grading guarantees hFE ≥ 220–480, reducing need for individual circuit trimming. |
| Low-noise AF performance | F ≤ 4 dB at 1 kHz enables use in precision analog front-ends without added noise filtering. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU and automotive ELV requirements for hazardous substance restriction. |

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 SOT23-3 package; hFE min = 200 (vs. 220); RthJS = 240 K/W (vs. 60 K/W). | Limited to lower-power AF stages due to higher thermal resistance; not AEC-Q101 qualified. | Select when cost sensitivity outweighs automotive qualification and thermal performance needs. |
| MMBT3904LT1G (ON Semiconductor) | VCEO = 40 V (vs. 45 V); hFE min = 100; fT = 300 MHz; Pb-free but not AEC-Q101 certified. | Higher fT supports faster digital switching, but lower VCEO restricts use in 36 V automotive rails. | Prefer for non-automotive high-speed logic interfacing where VCEO margin is less critical. |
Compared with BC847B,315 and MMBT3904LT1G, BC847BL3E6327XTMA1 delivers superior thermal performance (RthJS = 60 K/W), guaranteed higher hFE, and full AEC-Q101 compliance-making it the only choice for space-constrained, thermally demanding automotive modules requiring long-term reliability.

FAQ
What is the maximum junction temperature for BC847BL3E6327XTMA1?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in the Infineon datasheet. Operation above this limit risks permanent degradation of hFE and increased leakage. Derating is required above TS = 135 °C to maintain Ptot ≤ 250 mW, based on the measured RthJS = 60 K/W.
Is BC847BL3E6327XTMA1 pin-compatible with standard SOT23-3 transistors?
No-it uses the TSLP-3-1 package, which has identical pin numbering (E-B-C) but smaller dimensions (2.1 × 1.3 mm vs. 2.9 × 1.3 mm) and tighter 0.45 mm lead pitch. PCB footprints must be updated to avoid solder bridging or insufficient pad coverage.
Does BC847BL3E6327XTMA1 support pulsed operation beyond its DC power rating?
Yes-pulse operation up to Ptot(max)/Ptot(DC) = 10× is permitted for tp ≤ 10 ms (duty cycle ≤ 2%), per the permissible pulse load curve. This enables short-duration surge handling in motor drive gate buffers or LED strobe drivers without thermal runaway.
How does the AEC-Q101 qualification impact design validation for BC847BL3E6327XTMA1?
AEC-Q101 qualification confirms successful completion of accelerated stress tests-including HTGB, HTRB, temperature cycling, and ESD-specifically for discrete semiconductors. Designers may omit redundant qualification testing for automotive end-products, provided the device is used within its rated electrical and thermal limits as defined in the official Infineon datasheet.
