Product details
Overview
BC 817-16 E6433 from Nexperia 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, and VCE(sat) ≤ 0.7 V at IC = 500 mA / IB = 50 mA. It is used in low-voltage switching and linear amplification stages of power supply control circuits, LED drivers, and signal buffering in automotive body electronics.
For engineers reviewing the BC 817-16 E6433 datasheet, BC 817-16 E6433 pinout, BC 817-16 E6433 application, or BC 817-16 E6433 equivalent, key selection criteria include DC current gain group (hFE-grp.16), SOT23 package thermal resistance (RthJS ≤ 70 K/W), 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 hFE group 16 ensures predictable current amplification across IC = 10 mA to 500 mA at VCE = 1 V, and its low VCE(sat) supports efficient on-state conduction in 5–12 V logic-level drive applications.
The device features a maximum collector-emitter voltage of 45 V and collector-base voltage of 50 V, enabling use in intermediate-voltage DC-DC feedback paths and relay driver stages. Its fT = 170 MHz (IC = 50 mA, VCE = 5 V) confirms suitability for audio-band and low-speed digital signal conditioning-not RF or high-speed switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| hFE (IC = 100 mA) | 100–160 - Predictable DC current gain for stable biasing in amplifier and switch designs. |
| VCE(sat) | ≤ 0.7 V at IC = 500 mA / IB = 50 mA - Low on-state loss for efficient power switching. |
| fT | 170 MHz - Transition frequency confirming usable bandwidth up to ~10 MHz for small-signal amplification. |
| RthJS | ≤ 70 K/W - Junction-to-solder-point thermal resistance enabling 500 mW dissipation at TS ≤ 115 °C. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive electronic components including temperature cycling and HTRB. |
Pinout & Package
BC 817-16 E6433 is housed in a standard SOT23 plastic surface-mount package with gull-wing leads, rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink node; connects to ground or low-side return path in common-emitter configurations. |
| 2 (Base) | B | Control input; requires ~50 mA base drive to saturate at 500 mA collector current. |
| 3 (Collector) | C | Current source node; interfaces with load (e.g., relay coil, LED string, or next-stage transistor). |
Key Features
| Feature | Design Value |
|---|---|
| High hFE group consistency | hFE = 100–160 at IC = 100 mA enables accurate bias design without trimming resistors. |
| Low VCE(sat) | ≤ 0.7 V reduces power loss and self-heating in continuous 500 mA switching applications. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling and humidity exposure. |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C). |
Applications
| Automotive Body Control Module | Industrial Power Supply Feedback |
|---|---|
Use Scenario: Driving 12 V relay coils and status LEDs in door module PCBs. IC Role / Device Role / Timing Role: NPN switch controlling load current with TTL/CMOS-compatible base drive. Use Value: VCEO = 45 V provides margin against load-dump transients; AEC-Q101 ensures field reliability. | Use Scenario: Amplifying error signal from optocoupler in isolated flyback controller feedback loop. IC Role / Device Role / Timing Role: Linear amplifier stage converting photocurrent to voltage for PWM comparator input. Use Value: hFE = 100–160 ensures stable gain over temperature; fT = 170 MHz supports <100 kHz loop bandwidth. |
| LED Driver for Smart Lighting | Signal Level Shifting |
Use Scenario: Switching 350 mA white LED strings in DALI-enabled luminaires. IC Role / Device Role / Timing Role: Constant-current switch with base resistor network defining IC. Use Value: VCE(sat) ≤ 0.7 V limits heat rise in thermally constrained aluminum-core PCBs. | Use Scenario: Translating 3.3 V microcontroller GPIO to 5 V logic for legacy peripherals. IC Role / Device Role / Timing Role: Active pull-up level shifter using common-emitter topology. Use Value: High hFE allows low base current draw (<1 mA), preserving MCU drive capability. |
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 | Lower IC = 100 mA max; hFE = 200–450 (group B); VCEO = 45 V same. | Not suitable for 500 mA loads; better for low-power signal amplification. | Select when bias stability at µA–mA levels is prioritized over high-current switching. |
| MMBT3904LT1G | Same IC = 200 mA (not 500 mA); VCEO = 40 V; hFE = 100–300; RthJS = 200 K/W (SOT-23). | Limited to ≤200 mA continuous; higher thermal resistance restricts power handling. | Choose only for non-automotive, low-duty-cycle signal switching where cost is critical. |
Compared with BC847B,215 and MMBT3904LT1G, BC 817-16 E6433 uniquely supports 500 mA continuous collector current with automotive qualification and lower saturation voltage-making it the only option among the three qualified for AEC-Q101-compliant 12 V relay and LED driver designs.

FAQ
Is BC 817-16 E6433 pin-compatible with BC847 or MMBT3904?
Yes-BC 817-16 E6433 uses the standard SOT23 package with E-B-C pinout (1=E, 2=B, 3=C), matching BC847 and MMBT3904. However, its 500 mA IC rating exceeds both alternatives, so layout current-carrying capacity must be verified for full-load operation.
What is the maximum operating temperature for continuous 500 mA operation?
At IC = 500 mA and VCE(sat) ≈ 0.7 V, power dissipation is ~350 mW. With RthJS ≤ 70 K/W and TS ≤ 115 °C, junction temperature remains below 150 °C-within spec. Derating is required above 115 °C solder-point temperature.
Does BC 817-16 E6433 support pulse operation beyond 500 mA?
Yes-peak collector current ICM is 1000 mA for pulse widths < 300 µs and duty cycle < 2%. Pulse capability enables short-duration inrush current handling in relay and solenoid drivers without thermal runaway.
How does hFE group 16 differ from group 25 or 40 in practical circuit design?
hFE-grp.16 guarantees minimum hFE = 100 at IC = 100 mA, ensuring conservative base resistor sizing for reliable saturation. Group 25 (160–250) and 40 (250–400) allow smaller base resistors but increase sensitivity to hFE variation across temperature and unit-to-unit spread.
