Product details
Overview
BC806-16R from Nexperia is a PNP general-purpose bipolar junction 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 and IC = −100 mA. It is AEC-Q101 qualified and used in automotive 48 V board net switching and low-power amplification.
For engineers reviewing the BC806-16R datasheet, BC806-16R pinout, BC806-16R application, or BC806-16R equivalent, this page delivers verified electrical parameters, thermal derating behavior, base-emitter saturation voltage under load, and validated automotive-grade reliability data - all critical for discrete BJT selection in space-constrained, thermally demanding designs.
Technical Context
The BC806-16R operates as a medium-voltage, medium-current PNP switch with fixed-gain binning (hFE = 100–250), optimized for linear amplification and saturated switching in low-to-moderate power stages. Its −80 V VCEO rating supports operation across 48 V automotive rails with margin, while its −500 mA continuous collector current enables drive capability for small relays and LED arrays.
Thermal performance is defined by two mounting conditions: 500 K/W Rth(j-a) on standard FR4 footprint and 363 K/W with 1 cm² collector pad. The device exhibits −1.2 V VBE(sat) at IC = −500 mA and −10.5 mA IB, confirming robust base drive efficiency in high-current saturation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Maximum safe collector-emitter voltage before breakdown; enables use in 48 V systems with 66 % voltage headroom. |
| IC | −500 mA continuous: Supports driving loads such as small solenoids, logic-level interface buffers, or sensor bias networks. |
| hFE | 100–250 at VCE = −1 V, IC = −100 mA: Predictable current amplification for stable biasing in amplifier or switch configurations. |
| VCE(sat) | −400 mV max at IC = −500 mA, IB = −50 mA: Low saturation voltage minimizes conduction loss and self-heating during switching. |
| Ptot | 345 mW at Tamb ≤ 25 °C with 1 cm² collector pad: Defines maximum steady-state power dissipation under optimized PCB layout. |
| Tj(max) | 150 °C: Junction temperature limit enabling operation in under-hood automotive environments with proper thermal design. |
Pinout & Package
SOT23 (TO-236AB) surface-mount plastic package with 3 leads, 1.9 mm × 1.3 mm footprint, 0.95 mm height, and tin-plated terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires −10.5 mA typical base current to saturate at −500 mA collector load. |
| 2 | Emiter (E) | Current source terminal; connected to higher potential rail in PNP configuration (e.g., +48 V). |
| 3 | Collector (C) | Output terminal; sinks current to load and PCB ground; thermally coupled to mounting pad for heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including 48 V board net switching, with full stress-test compliance per discrete semiconductor standard. |
| Two hFE bins | BC806-16R (100–250) and BC806-25R (160–400) enable precise gain matching in analog circuits or consistent switching thresholds in digital interfaces. |
| High VCEO rating | −80 V allows reliable operation in transient-prone 48 V systems without clamping components, reducing BOM count. |
| Low VBE(sat) | −1.2 V max at IC = −500 mA ensures efficient base drive with standard logic-level microcontrollers or gate drivers. |
Applications
| Automotive 48 V Board Net Switching | Industrial Sensor Biasing |
|---|---|
Use Scenario: Controlling power delivery to auxiliary modules (e.g., HVAC actuators, lighting controllers) on 48 V vehicle architectures. IC Role / Device Role / Timing Role: PNP switch providing high-side current control with fast turn-on/turn-off response and low saturation loss. Use Value: −400 mV VCE(sat) at −500 mA reduces power loss to < 200 mW, minimizing thermal stress in compact ECU enclosures. |
Use Scenario: Supplying stable bias current to precision analog sensors (e.g., pressure transducers, RTD interfaces) in factory automation PLCs. IC Role / Device Role / Timing Role: Constant-current source configured in emitter-follower topology for low-noise, temperature-stable excitation. Use Value: hFE range of 100–250 enables predictable current mirroring accuracy within ±5 % over −40 °C to +125 °C ambient. |
| Consumer Power Management | Medical Diagnostic Instrumentation |
Use Scenario: Enabling/disabling power rails in portable ultrasound or infusion pump subsystems requiring low quiescent current and fail-safe shutdown. IC Role / Device Role / Timing Role: High-side load switch with integrated base resistor network (in companion variants) or discrete base drive for safety-critical sequencing. Use Value: −8 V VEBO rating ensures immunity to reverse-battery transients up to −8 V, supporting robust front-end protection schemes. |
Use Scenario: Isolating signal paths between patient-connected analog front-ends and digital processing units in ECG or EEG devices. IC Role / Device Role / Timing Role: Signal-level amplifier stage providing galvanic isolation and gain stability across medical-grade temperature ranges. Use Value: 80 MHz fT supports bandwidth-critical amplification of bio-signals up to 10 kHz with minimal phase shift and distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-16 | Same package and hFE bin, but NPN polarity; VCEO = +45 V, IC = +500 mA. | Requires circuit redesign for low-side switching or inverted logic interface; not drop-in for high-side PNP roles. | Select only when NPN topology is preferred and supply polarity permits. |
| MMBT3906 | Same PNP polarity, but lower VCEO (−40 V), lower IC (−200 mA), and hFE = 100–300. | Not suitable for 48 V automotive net; limited to ≤24 V industrial or consumer applications. | Choose only for cost-sensitive, non-automotive designs where voltage and current demands are reduced. |
Compared with BC806-16R, BC807-16 offers complementary NPN functionality but cannot replace high-side PNP switching in 48 V systems, while MMBT3906 lacks the voltage headroom and current capacity required for automotive-grade reliability - making BC806-16R the only option qualified and rated for AEC-Q101-compliant 48 V board net use.

FAQ
Is BC806-16R suitable for high-frequency signal amplification?
No. While its transition frequency (fT) is 80 MHz, the BC806-16R is optimized for switching and low-to-mid-frequency amplification (≤10 kHz). Its gain-bandwidth trade-off and thermal limitations make it unsuitable for RF or broadband analog applications above 1 MHz.
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, the recommended IB is ≤ −50 mA - sufficient to saturate the device at −500 mA IC with margin, while maintaining thermal stability on standard FR4 PCBs.
Does BC806-16R require external base resistors in switching applications?
Yes. As a bare transistor, BC806-16R has no integrated base resistor. External base resistance must be selected to deliver −10.5 mA to −50 mA depending on target IC and drive voltage, ensuring saturation without exceeding IB(max) or inducing excessive power dissipation in the driver stage.
How does thermal derating affect power handling at 85 °C ambient?
At Tamb = 85 °C, the total power dissipation must be reduced to ~200 mW (from 345 mW at 25 °C) using the 363 K/W Rth(j-a) curve. This corresponds to a maximum continuous IC of ~350 mA at VCE(sat) ≈ −400 mV, assuming optimal PCB copper area and airflow.
