Product details

Overview

BC 817-16 E6327 from Infineon Technologies is an NPN silicon general-purpose audio-frequency transistor with hFE = 100–160 (at IC = 100 mA, VCE = 1 V), VCEO = 45 V, IC = 500 mA continuous, and VCE(sat) ≤ 0.7 V at IC = 500 mA / IB = 50 mA - used in low-voltage switching and linear amplification stages of power management and signal conditioning circuits.

For engineers reviewing the BC 817-16 E6327 datasheet, BC 817-16 E6327 pinout, BC 817-16 E6327 application, or BC 817-16 E6327 equivalent, key selection criteria include DC current gain group (hFE-grp.16), SOT-23 package thermal resistance (RthJS ≤ 70 K/W), saturation voltage performance under high-current drive, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This NPN bipolar junction transistor operates in active, saturation, and cutoff regions for analog amplification and digital switching. Its design supports stable hFE across −40 °C to 105 °C and maintains VCE(sat) ≤ 0.7 V at IC/IB = 10, enabling efficient low-side switch operation in 5–24 V rail systems.

It features low Ccb = 3 pF and Ceb = 40 pF at specified bias conditions, supporting bandwidths up to fT = 170 MHz - suitable for AF and low-MHz signal routing where parasitic capacitance must be minimized without requiring RF-optimized layout.

Key Specifications

ParameterValue and Actual Design Meaning
VCEO45 V - maximum collector-emitter voltage before breakdown; enables use in 36 V automotive and industrial supply rails.
hFE (IC = 100 mA)100–160 - guaranteed DC current gain range for hFE-grp.16; ensures predictable base drive sizing in linear and switching designs.
VCE(sat)≤ 0.7 V at IC = 500 mA / IB = 50 mA - low saturation voltage reduces conduction loss in high-current switching nodes.
fT170 MHz - transition frequency at IC = 50 mA / VCE = 5 V; supports audio and sub-MHz signal amplification with minimal phase shift.
RthJS≤ 70 K/W - junction-to-soldering-point thermal resistance (SOT-23); allows 500 mW dissipation up to TS = 115 °C.
AEC-Q101Qualified - certified for automotive electronics per stress test standard; validated for temperature cycling, HTRB, and ESD robustness.

Pinout & Package

BC 817-16 E6327 is housed in a RoHS-compliant SOT-23 plastic surface-mount package with gull-wing leads, optimized for automated placement and reflow soldering on dense PCBs.

Pin/TerminalCircuit RoleDesign Meaning
1 (Emitter)ECurrent sink node; connected to ground or low-impedance return path in common-emitter configurations.
2 (Base)BControl input; requires current-limited drive (e.g., via series resistor) to achieve target hFE-dependent collector current.
3 (Collector)CCurrent source node; ties to load or higher-potential rail; handles up to 500 mA continuous with thermal derating.

Key Features

FeatureDesign Value
High current gain grouphFE = 100–160 (grp.16) - enables precise base current calculation for consistent IC control in feedback and driver circuits.
Low VCE(sat)≤ 0.7 V at IC = 500 mA - minimizes power loss and self-heating in high-duty-cycle switching applications.
AEC-Q101 qualificationValidated for automotive environments - ensures reliability under thermal shock, humidity, and vibration stress per industry standard.
SOT-23 footprintStandardized 3-pin leaded package - compatible with legacy pick-and-place equipment and IPC-7351B land patterns.

IC Role / Device Role / Timing Role: Constant-current source configured in emitter-follower topology with precision base voltage reference.

Use Value: Tight hFE grouping (100–160) reduces unit-to-unit variation in bias current; low Ceb avoids signal coupling into sensitive analog paths.

Equivalent & Alternatives

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

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
BC847B,215 (Nexperia)hFE = 200–450 (grp.B), VCEO = 45 V, same SOT-23 package, but lower IC = 100 mA max.Not suitable for >100 mA switching; better for small-signal amplification than power switching.Select when gain consistency matters more than current handling; verify base drive compatibility due to higher hFE.
MMBT3904LT1G (ON Semiconductor)hFE = 100–300 (grp.1), VCEO = 40 V, IC = 200 mA, SOT-23, AEC-Q101 qualified.Limited to 200 mA continuous; lower VCEO reduces margin in 36 V systems.Use where lower cost and broad distributor availability outweigh need for 500 mA capability and 45 V rating.

Compared with BC847B,215 and MMBT3904LT1G, BC 817-16 E6327 delivers higher continuous collector current (500 mA vs. ≤200 mA), tighter hFE grouping for predictable drive, and superior thermal performance in SOT-23 - making it preferred for automotive and industrial switching where current and reliability are critical.

FAQ

Is BC 817-16 E6327 pin-compatible with BC847 or MMBT3904?

Yes - all three use standard SOT-23 with identical pinout (E-B-C). However, BC 817-16 E6327 has higher IC (500 mA vs. 100–200 mA) and different hFE grouping; verify base drive and thermal design when substituting.

What is the maximum allowable junction temperature?

The absolute maximum junction temperature (Tj) is 150 °C. Operation above this risks permanent degradation. Derate total power dissipation linearly beyond TS = 115 °C per the Ptot vs. TS curve in the datasheet.

Does BC 817-16 E6327 support pulsed operation beyond 500 mA?

Yes - peak collector current (ICM) is rated at 1000 mA for pulse widths < 300 µs and duty cycle < 2%. Thermal limits still apply; ensure pulse energy stays within safe operating area (SOA) boundaries.

How does AEC-Q101 qualification impact its use in non-automotive applications?

AEC-Q101 validation confirms robustness against temperature cycling, high-temperature reverse bias, and electrostatic discharge - providing enhanced reliability margins for industrial, medical, and high-reliability consumer applications even outside automotive contexts.
