Product details
Overview
BC816-16HR from Nexperia is an NPN general-purpose transistor in SOT23 (TO-236AB) package, rated for 80 V VCEO, 500 mA continuous collector current, and DC current gain (hFE) of 100–250 at VCE = 1 V, IC = 100 mA. It operates reliably up to 175 °C junction temperature and serves as a robust switching element in 48 V automotive board nets and industrial control logic.
For engineers reviewing the BC816-16HR datasheet, BC816-16HR pinout, BC816-16HR application, or BC816-16HR equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternatives for high-reliability discrete switching designs.
Technical Context
This transistor uses epitaxial planar silicon technology with optimized base doping and geometry to achieve stable hFE across temperature (−55 °C to +175 °C) and low VCE(sat) ≤ 400 mV at IC = 500 mA / IB = 50 mA. Its 80 V VCEO rating supports operation in 48 V systems with margin against transients.
The device exhibits low parasitic capacitance-Cc = 2 pF at VCB = 10 V and Ce = 42 pF at VEB = 0.5 V-enabling use in medium-speed switching (fT = 100 MHz) without excessive Miller effect or delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 48 V board net surges with ≥1.6× safety margin under open-base condition. |
| IC (continuous) | 500 mA - Supports load switching up to ~24 W at 48 V with appropriate heatsinking. |
| hFE | 100–250 - Enables reliable saturation with base drive ≤5 mA at 500 mA collector load. |
| VCE(sat) | ≤400 mV @ IC/IB = 10 - Limits conduction loss to <200 mW, reducing thermal stress in compact layouts. |
| Tj(max) | 175 °C - Permits operation in under-hood automotive environments and sealed industrial enclosures. |
| Rth(j-a) | 500 K/W (standard footprint) - Requires PCB copper area management for >150 mW power dissipation. |
| fT | 100 MHz - Suitable for PWM frequencies up to ~10 MHz with acceptable gain roll-off. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads; 1.3 mm profile height, 2.9 mm × 1.3 mm body, and standard reflow-compatible footprint per Figure 29.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input; requires current-limited drive (max 200 mA pulsed) to avoid secondary breakdown. |
| 2 | Emitter (E) | Reference node for biasing; connected to ground or low-side return path in common-emitter switches. |
| 3 | Collector (C) | High-side load connection; electrically isolated from PCB pad in standard mounting (no thermal pad). |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage capability | 80 V VCEO enables direct use in 48 V automotive and industrial power rails without series stacking. |
| High-temperature operation | Rated to 175 °C Tj with no derating required up to 125 °C ambient-ideal for engine-control modules. |
| Precision hFE binning | 100–250 range ensures predictable base drive requirements across production lots. |
| Low saturation voltage | VCE(sat) ≤ 400 mV at full 500 mA load minimizes self-heating and improves efficiency in linear-regulator pass elements. |
| Fast transition frequency | fT = 100 MHz supports clean edge integrity in digital logic interface and PWM gate driving applications. |
Applications
| Automotive 48 V Board Net Switching | Industrial PLC Input Stage |
|---|---|
Use Scenario: Controlling solenoid valves and LED arrays on 48 V vehicle chassis networks. IC Role / Device Role / Timing Role: NPN switch in common-emitter configuration, driven by microcontroller GPIO with base resistor. Use Value: 80 V VCEO withstands load-dump transients; 175 °C rating avoids thermal shutdown during extended duty cycles. |
Use Scenario: Level-shifting and isolation between 24 V field sensors and 3.3 V/5 V controller inputs. IC Role / Device Role / Timing Role: Discrete NPN translator providing galvanic separation and current gain for optocoupler drivers. Use Value: Low VCE(sat) ensures minimal voltage drop across sensor interface; hFE stability maintains signal fidelity over temperature. |
| DC-DC Converter Feedback Loop | Power Supply Enable Circuit |
Use Scenario: Amplifying error amplifier output to drive optocoupler LED in isolated flyback feedback paths. IC Role / Device Role / Timing Role: Linear-mode current amplifier operating below fT limit with fixed bias. Use Value: 100 MHz fT preserves loop bandwidth; low Cc (2 pF) prevents phase lag in compensation network. |
Use Scenario: Enabling high-current PMICs or LDOs via microcontroller-controlled enable line. IC Role / Device Role / Timing Role: Low-side enable switch sinking enable pin current (typically 1–10 µA to 100 µA). Use Value: High hFE allows single GPIO to control multiple enables; 500 mA IC headroom ensures long-term reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC816-25H | hFE = 160–400 (vs. 100–250); otherwise identical ratings and package. | Better suited for low-base-drive designs where precise gain matching is less critical than drive margin. | Select when higher hFE reduces MCU GPIO loading or simplifies base resistor selection. |
| MMBT3904LT1G | VCEO = 40 V (vs. 80 V); Ptot = 310 mW (vs. 415 mW); hFE = 100–300. | Not suitable for 48 V systems due to insufficient voltage margin; limited to ≤24 V applications. | Choose only for cost-sensitive ≤24 V consumer electronics where 80 V rating is unnecessary. |
Compared with BC816-25H, BC816-16HR offers tighter hFE control for predictable base drive; versus MMBT3904LT1G, it provides essential 80 V surge tolerance for automotive-grade 48 V net compliance.

FAQ
Is BC816-16HR qualified for automotive applications?
No. Per Nexperia's revision history (Rev. 2, 30 September 2025), BC816-16HR is explicitly non-automotive qualified. It lacks AEC-Q101 testing and qualification. For automotive use, Nexperia recommends its -Q qualified variants such as BC816-16Q, which undergo full stress testing per AEC standards.
What is the maximum allowable base current for continuous operation?
The absolute maximum pulsed base current is 200 mA (tp ≤ 1 ms), but continuous base current must be limited by thermal design. At IC = 500 mA and hFE = 100, nominal IB = 5 mA. Derating is required above 25 °C ambient; Rth(j-a) = 500 K/W implies >100 mW base power dissipation risks exceeding Tj(max).
Can BC816-16HR replace BC846B in existing designs?
No. BC846B has VCEO = 65 V and hFE = 200–450, but its SOT23 pinout is emitter-collector swapped (E-C-B vs. B-E-C). Physical insertion would reverse polarity, causing immediate failure. Electrical replacement requires circuit redesign and layout modification.
Does BC816-16HR have a thermal pad or exposed collector?
No. The SOT23 package used for BC816-16HR has no thermal pad or exposed collector terminal. Thermal performance relies entirely on PCB copper area under pins 2 (emitter) and 3 (collector), with documented derating curves assuming standard FR4 footprint (1 cm² collector pad improves Ptot to 415 mW).
