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
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 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. |
| fT | 170 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-Q101 | Qualified - 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/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink node; connected to ground or low-impedance return path in common-emitter configurations. |
| 2 (Base) | B | Control input; requires current-limited drive (e.g., via series resistor) to achieve target hFE-dependent collector current. |
| 3 (Collector) | C | Current source node; ties to load or higher-potential rail; handles up to 500 mA continuous with thermal derating. |
Key Features
| Feature | Design Value |
|---|---|
| High current gain group | hFE = 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 qualification | Validated for automotive environments - ensures reliability under thermal shock, humidity, and vibration stress per industry standard. |
| SOT-23 footprint | Standardized 3-pin leaded package - compatible with legacy pick-and-place equipment and IPC-7351B land patterns. |
Applications
| Automotive Door Module Driver | Industrial PLC Input Isolation |
|---|---|
Use Scenario: Driving 12 V solenoid locks and LED status indicators in vehicle door control units. IC Role / Device Role / Timing Role: NPN switch controlling load current with logic-level base drive from microcontroller GPIO. Use Value: Low VCE(sat) limits heat generation during repeated actuation; AEC-Q101 rating ensures long-term field reliability. | Use Scenario: Optocoupler input stage isolation for 24 V DC digital inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Signal-level transistor amplifying weak opto-output current to drive Schmitt-trigger input buffers. Use Value: Stable hFE over temperature ensures consistent threshold crossing; SOT-23 saves board space in multi-channel I/O modules. |
| Consumer Appliance Power Sequencing | Medical Sensor Biasing Circuit |
Use Scenario: Enabling sequential power-up of auxiliary rails (e.g., display backlight, fan control) in smart home appliances. IC Role / Device Role / Timing Role: Low-side enable switch activated by MCU after primary rail stabilization. Use Value: 45 V VCEO headroom accommodates transient spikes on 24 V supplies; RthJS ≤ 70 K/W supports sustained 300 mA loads. | Use Scenario: Providing stable bias current to photodiode or thermistor front-end amplifiers in portable diagnostic devices. 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 Part | Technical Difference | Application Difference | Selection 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.
