Product details
Overview
BC817-16B5000 from Nexperia is an NPN silicon general-purpose audio-frequency transistor in SOT23 package, rated for 45 V VCEO, 500 mA IC, and 330 mW Ptot at TS ≤ 79 °C, with hFE = 100–160 (IC = 100 mA, VCE = 1 V), VCE(sat) ≤ 0.7 V (IC = 500 mA, IB = 50 mA), and fT = 170 MHz - used in low-voltage switching and signal amplification stages of power supply control circuits.
For engineers reviewing the BC817-16B5000 datasheet, BC817-16B5000 pinout, BC817-16B5000 application, or BC817-16B5000 equivalent, key selection criteria include guaranteed hFE group 16 performance across temperature, low VCE(sat) under high-current drive, RoHS-compliant SOT23 footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a medium-power NPN bipolar junction transistor optimized for linear amplification and saturated switching in DC-coupled or capacitively coupled AF signal paths. Its design emphasizes stable current gain over temperature (hFE maintained ≥60 at IC = 300 mA, VCE = 1 V) and low saturation voltage to minimize conduction losses in driver stages.
The BC817-16B5000 shares pinout and thermal characteristics with BC817-16 variants but is specifically marked "B5000" per Nexperia's tape-and-reel packaging code for 5,000-unit reels. It is not a logic-level or RF-optimized transistor - its fT and Ccb/Ceb values confirm suitability for ≤100 MHz applications only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - supports operation in 24 V and 36 V rail systems with 2× safety margin against transients. |
| IC | 500 mA continuous - drives small relays, LED strings, or MOSFET gates without external heat sinking below 79 °C board temperature. |
| hFE (100 mA) | 100–160 - enables predictable base current sizing (e.g., ~3–5 mA for 500 mA collector load) in Class-A amplifier or switch designs. |
| VCE(sat) | ≤0.7 V @ IC = 500 mA, IB = 50 mA - limits power dissipation to ≤350 mW during saturation, compatible with 330 mW derated Ptot. |
| fT | 170 MHz - sufficient for audio preamp gain stages and PWM frequency modulation up to 50 kHz with phase margin. |
| RthJS | ≤215 K/W - requires PCB copper area ≥25 mm² for thermal relief when operating near max Ptot at ambient >50 °C. |
Pinout & Package
BC817-16B5000 uses the standard SOT23 surface-mount package (3.0 × 1.4 × 1.1 mm), with plastic body, gull-wing leads, and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires series resistor to limit IB and prevent thermal runaway under VBE > 1.2 V. |
| 2 | Emitter (E) | Reference terminal for biasing; connected to ground or negative rail in common-emitter configurations. |
| 3 | Collector (C) | Output current sink node; routed to load (e.g., relay coil or pull-up resistor) with trace width ≥0.3 mm for 500 mA. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTOL, TC, and ESD-HBM ≥2 kV. |
| hFE group 16 binning | Guaranteed 100–160 gain range ensures consistent bias point setting across production lots without recalibration. |
| Low VCE(sat) | ≤0.7 V at full rated current reduces power loss by ≥30% versus generic BC817-25/40 in saturated switch applications. |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU with <1000 ppm lead content; compatible with lead-free reflow profiles (peak 260 °C). |
Applications
| Power Supply Enable Switch | Microcontroller GPIO Driver |
|---|---|
Use Scenario: Enabling/disabling a 12 V DC-DC converter output stage using MCU logic-level signal. IC Role / Device Role / Timing Role: NPN switch controlling high-side PMOS gate via open-collector configuration with pull-up resistor. Use Value: VCE(sat) ≤0.7 V ensures <8.4 mW dissipation at 500 mA, eliminating need for heatsink in space-constrained SMPS modules. |
Use Scenario: Driving a 20 mA indicator LED from a 3.3 V microcontroller I/O pin with current limiting. IC Role / Device Role / Timing Role: Low-gain current amplifier converting weak GPIO output into robust LED sink path. Use Value: hFE ≥100 allows 200 µA base drive to achieve 20 mA LED current - preserving MCU drive capability for other peripherals. |
| Automotive Door Lock Actuator | Industrial Sensor Signal Conditioning |
Use Scenario: Controlling solenoid-based door lock mechanism in 12 V vehicle electrical system. IC Role / Device Role / Timing Role: Medium-current switch interfacing CAN/LIN controller outputs to inductive load. Use Value: AEC-Q101 qualification and 150 °C Tj rating ensure reliable operation inside door modules exposed to cabin temperature extremes. |
Use Scenario: Amplifying low-level analog output (e.g., 0–100 mV) from strain gauge bridge before ADC sampling. IC Role / Device Role / Timing Role: Fixed-bias common-emitter amplifier with emitter degeneration resistor for linearity. Use Value: Stable hFE vs. temperature (±15% from −40 °C to 105 °C) maintains gain accuracy across industrial ambient ranges. |
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 |
|---|---|---|---|
| BC817-16,115 (Nexperia) | Same die, identical hFE group and ratings; differs only in tape-and-reel packaging (115 = 3,000 pcs/reel vs. B5000 = 5,000 pcs/reel). | No functional difference; suitable for same PCB layouts and thermal designs. | Select based on procurement volume and reel size alignment with SMT line feeder capacity. |
| MMBT3904LT1G (onsemi) | Lower VCEO (40 V), higher VCE(sat) (≤0.3 V @ IC = 10 mA but ≤0.8 V @ IC = 200 mA), hFE = 100–300 (wider spread). | Not AEC-Q101 qualified; unsuitable for automotive environments requiring stress validation. | Prefer for cost-sensitive consumer electronics where AEC-Q101 is unnecessary and tighter hFE tolerance is not required. |
Compared with BC817-16B5000, BC817-16,115 offers identical electrical behavior with different packaging logistics, while MMBT3904LT1G trades automotive qualification and hFE consistency for broader gain range and lower unit cost in non-automotive use cases.

FAQ
Is BC817-16B5000 pin-compatible with BC847 or 2N3904?
No. BC817-16B5000 uses SOT23 package with Base-Emitter-Collector pin order (1-2-3), while BC847 and 2N3904 in SOT23 follow Emitter-Base-Collector (1-2-3) layout. Physical insertion into same footprint will reverse polarity and cause immediate failure. Always verify pin configuration using manufacturer-provided diagrams.
What is the maximum safe operating current at 85 °C ambient?
At 85 °C ambient, derated Ptot is approximately 220 mW (per RthJS ≤215 K/W and Tj(max) = 150 °C). With VCE(sat) ≈0.65 V, this limits continuous IC to ~340 mA. For sustained 500 mA operation, board temperature must remain ≤79 °C per datasheet thermal curve.
Does BC817-16B5000 support pulsed operation above 500 mA?
Yes - peak collector current ICM is rated at 1000 mA for pulse widths ≤300 µs and duty cycle ≤2%. Pulse operation must respect the Ptotmax/PtotDC vs. tp curve (Fig. 7); at 100 µs pulse width, allowable peak power is ~4× DC rating, enabling short-duration surge handling in motor commutation or solenoid kickback suppression.
Can BC817-16B5000 replace BC817-25 in existing designs?
Only if circuit gain requirements align: BC817-16B5000 has hFE = 100–160, whereas BC817-25 specifies 160–250. Substituting may reduce base drive margin or cause incomplete saturation in high-current switches. Verify actual hFE usage in your bias network before replacement; no change is needed for linear amplifier stages with feedback.
