Product details
Overview
BC816-16H-Q from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT23 (TO-236AB) package, rated for 80 V VCEO, 500 mA IC, and DC current gain (hFE) of 100–250 at VCE = 1 V, IC = 100 mA. It operates up to 175 °C junction temperature and serves as a robust switching or amplification device in 48 V automotive board nets.
For engineers reviewing the BC816-16H-Q datasheet, BC816-16H-Q pinout, BC816-16H-Q application, or BC816-16H-Q equivalent, this page delivers verified electrical parameters, thermal derating behavior, automotive qualification status, and real-world use context for high-reliability discrete selection.
Technical Context
This NPN bipolar junction transistor features a planar epitaxial die structure optimized for stable DC current gain across wide temperature ranges (−55 °C to +175 °C) and exhibits low VCE(sat) of ≤400 mV at IC = 500 mA and IB = 50 mA. Its 80 V collector-emitter breakdown voltage supports operation in 48 V automotive systems with margin against transients.
The device uses standard SOT23 footprint with defined reflow and wave soldering land patterns, and its thermal resistance Rth(j-a) is 500 K/W on FR4 PCB with standard footprint-critical for thermal design in space-constrained modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 48 V automotive supply rail transients without breakdown |
| IC | 500 mA continuous - Supports medium-power load switching (e.g., solenoids, LED arrays) |
| hFE | 100–250 @ VCE=1 V, IC=100 mA - Enables predictable base drive sizing for saturation |
| VCE(sat) | ≤400 mV @ IC=500 mA, IB=50 mA - Minimizes conduction loss and self-heating in switching mode |
| Tj(max) | 175 °C - Certified for under-hood automotive environments with no derating below 150 °C |
| Q-grade | AEC-Q101 qualified - Meets stress test requirements for automotive discrete semiconductors |
| Cc | 2 pF @ VCB=10 V - Low collector capacitance supports >100 MHz transition frequency (fT) |
Pinout & Package
BC816-16H-Q is housed in a standard SOT23 (TO-236AB) plastic surface-mount package measuring 2.9 mm × 1.3 mm × 1.0 mm, with gull-wing leads compatible with automated assembly and IPC-7351B footprint standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires ~50 mA drive for full saturation at 500 mA collector current |
| 2 | Emitter (E) | Current return path; internally connected to substrate; must be tied to lowest potential in switch configuration |
| 3 | Collector (C) | High-side load connection; electrically isolated from package tab; rated for 80 V blocking |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage capability | 80 V VCEO enables direct use in 48 V battery architectures without external clamping |
| Automotive qualification | AEC-Q101 compliance ensures reliability for safety-critical non-safety subsystems (e.g., HVAC, lighting control) |
| High-temperature operation | Rated up to 175 °C junction temperature-no derating required for under-dash or engine bay mounting |
| Two hFE grades | BC816-16H-Q (100–250) and BC816-25H-Q (160–400) allow precise gain matching in analog feedback paths |
| Low saturation voltage | VCE(sat) ≤ 400 mV reduces power dissipation by >30% vs. legacy 1 V typical devices at same IC |
Applications
| Automotive Body Control Module | Industrial 48 V DC Power Distribution |
|---|---|
Use Scenario: Driving 12 W incandescent lamp loads in door module logic outputs. IC Role / Device Role / Timing Role: NPN switch controlling ground-return path for lamps; operates in saturated on/off mode with <10 µs turn-on/turn-off. Use Value: 80 V rating absorbs load dump spikes up to 65 V; 175 °C rating prevents thermal shutdown during prolonged lamp-on cycles. |
Use Scenario: Enabling/disabling auxiliary 48 V rails in programmable power supplies. IC Role / Device Role / Timing Role: Medium-current series pass switch in discrete OR-ing or hot-swap circuitry. Use Value: 500 mA IC and 400 mV VCE(sat) limit insertion loss to <200 mW per channel at full load. |
| Consumer Appliance Motor Driver Stage | Medical Portable Equipment Power Sequencing |
Use Scenario: Level-shifting and current amplification for microcontroller-driven brushed DC motor H-bridge enable signals. IC Role / Device Role / Timing Role: Digital interface buffer between 3.3 V logic and 24–48 V motor supply domains. Use Value: 100–250 hFE ensures reliable saturation with minimal GPIO current; SOT23 footprint saves board area in compact enclosures. |
Use Scenario: Controlling power-up sequence of isolated sensor subassemblies in battery-powered diagnostic tools. IC Role / Device Role / Timing Role: Discrete enable switch for regulated 5 V/3.3 V rails with controlled rise time via base resistor. Use Value: AEC-Q101 qualification provides traceable reliability data for medical OEM documentation; 7 V VEBO supports safe biasing from auxiliary LDOs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC816-25H-Q | Higher hFE range (160–400) at same VCEO/IC ratings; identical package and pinout | Better suited for low-base-drive designs (e.g., weak MCU GPIOs); may require adjusted base resistor for same IC | Select when tighter hFE tolerance or lower IB is needed; verify stability under worst-case gain spread |
| MMBT3904LT1G | Lower VCEO (40 V), lower IC (200 mA), wider hFE spread (100–300), same SOT23 package | Not suitable for 48 V systems; limited to 24 V or lower rails; higher thermal resistance (625 K/W) | Acceptable only in non-automotive, low-voltage (<30 V), low-current (<200 mA) applications where AEC-Q101 is not required |
Compared with BC816-25H-Q, the BC816-16H-Q offers tighter hFE control for predictable base drive; compared with MMBT3904LT1G, it delivers 2× voltage headroom and 2.5× current capacity with automotive qualification-making it irreplaceable in 48 V board-net switching.

FAQ
Is BC816-16H-Q suitable for linear amplification applications?
Yes-it maintains stable hFE from −55 °C to +175 °C and exhibits low VBE variation (0.5–1.2 V) across IC = 1 mA to 500 mA, enabling predictable small-signal gain in Class-A amplifier stages. However, its 500 mA IC limit and 415 mW Ptot (with heatsink pad) constrain output power to <100 mW in continuous operation.
What is the maximum allowable base current for continuous operation?
The absolute maximum peak base current is 200 mA (single pulse, tp ≤ 1 ms), but for continuous DC operation, IB must be limited to ensure junction temperature stays ≤175 °C. At IC = 500 mA and hFE = 100, IB = 5 mA is sufficient; sustained IB > 10 mA requires thermal analysis due to internal power dissipation in the base-emitter junction.
Does BC816-16H-Q have a built-in ESD protection diode?
No-the device has no integrated ESD protection. Its ESD rating is unclassified per JESD22-A114 (HBM), and external protection (e.g., 100 Ω series resistor + 10 nF bypass to ground) is recommended for handling and PCB-level transient suppression, especially in automotive assembly lines where static discharge exceeds 2 kV.
Can BC816-16H-Q replace BC846B in existing designs?
Only with circuit validation: BC816-16H-Q has 2× higher VCEO (80 V vs. 65 V) and 2.5× higher IC (500 mA vs. 100 mA), but its hFE min is lower (100 vs. 200) and VCE(sat) is higher (400 mV vs. 300 mV typical). Base resistor values and thermal layout must be re-evaluated to avoid unintended saturation margin loss or overheating.
