Product details
Overview
BC806-16H-Q from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 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 operates up to 175 °C and is AEC-Q101 qualified for automotive board-net switching.
For engineers reviewing the BC806-16H-Q datasheet, BC806-16H-Q pinout, BC806-16H-Q application, or BC806-16H-Q equivalent, this page delivers verified electrical specs, thermal derating behavior, automotive-grade reliability data, and real-world switching use cases in 48 V systems.
Technical Context
This discrete PNP BJT supports high-voltage switching in automotive and industrial power rails, with VCEO = −80 V and VCBO = −80 V enabling robust operation in transient-prone 48 V board nets. Its hFE range (100–250) and low VCE(sat) (−400 mV max at IC = −500 mA, IB = −50 mA) support efficient current amplification and saturation switching.
Thermal performance is defined by Rth(j-a) = 500 K/W on standard FR4 PCB and 363 K/W with 1 cm² collector pad, enabling stable operation up to Tj = 175 °C. The device's fT = 80 MHz ensures adequate bandwidth for medium-speed digital switching and analog amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 48 V automotive systems with margin against load-dump transients. |
| IC | −500 mA - Continuous collector current rating at 25 °C; supports medium-power switching loads like relays and LED drivers. |
| hFE | 100–250 - DC current gain at VCE = −1 V, IC = −100 mA; ensures predictable base drive requirements for reliable saturation. |
| VCE(sat) | −400 mV max - Collector-emitter saturation voltage at IC = −500 mA, IB = −50 mA; minimizes conduction loss in high-current switching paths. |
| Tj(max) | 175 °C - Maximum junction temperature; validated per AEC-Q101 for under-hood automotive environments. |
| fT | 80 MHz - Transition frequency at VCE = −5 V, IC = −50 mA; supports switching frequencies up to ~10 MHz with usable gain. |
| Rth(j-a) | 500 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; informs heatsinking needs for continuous 500 mA operation. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads; compact 2.9 × 1.3 × 1.0 mm footprint optimized for high-density automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires −10 mA typical base drive to saturate at −500 mA collector current. |
| 2 | Emitter (E) | Current source terminal; connected to higher potential rail (e.g., +48 V) in high-side switch configurations. |
| 3 | Collector (C) | Current sink terminal; routed to load (e.g., relay coil or LED string) and grounded reference. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and 48 V board-net switching. |
| High-temperature operation | Junction rated to 175 °C, supporting under-hood placement without derating in ambient up to 125 °C. |
| Two hFE grades | BC806-16H-Q (100–250) and BC806-25H-Q (160–400) allow precise base-drive optimization across production lots. |
| Low VCE(sat) | ≤ −400 mV at full rated current ensures <100 mW conduction loss, reducing thermal stress in space-constrained modules. |
| Robust voltage ratings | VCEO = VCBO = −80 V provides 67 % headroom above nominal 48 V systems, improving surge immunity. |

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 |
|---|---|---|---|
| BC806-25H-Q | Higher hFE (160–400) at same VCEO/IC; identical package and thermal specs. | Better suited for low-base-drive designs (e.g., weak GPIOs); may require resistor recalibration in existing circuits. | Select when base current budget is constrained or tighter hFE consistency is needed across temperature. |
| MMBT3906LT1G | Lower VCEO (−40 V), lower IC (−200 mA), wider hFE spread (30–300), no AEC-Q101 qualification. | Limited to 12 V/24 V non-automotive applications; unsuitable for 48 V transients or under-hood use. | Acceptable only for cost-sensitive consumer or prototyping use where voltage/temperature margins are relaxed. |
Compared with BC806-25H-Q and MMBT3906LT1G, BC806-16H-Q uniquely balances automotive-grade reliability, 48 V system compatibility, and predictable mid-range hFE-making it optimal for production-grade 48 V switching where base drive is well-controlled and transient immunity is mandatory.

FAQ
What is the maximum allowable base current for BC806-16H-Q?
The absolute maximum peak base current is −200 mA per the limiting values table. For continuous operation, design base current to maintain IC/IB ≤ 10–20 to ensure saturation while staying within the 300 mW total power dissipation limit at 25 °C ambient.
Can BC806-16H-Q replace BC806-25H-Q in an existing design?
Yes, but verify base resistor values: BC806-16H-Q's lower hFE (100–250 vs. 160–400) may require reduced RB to maintain saturation at full IC. Also confirm that the circuit does not rely on the tighter hFE distribution of the -25 variant for precision current setting.
Is BC806-16H-Q suitable for linear amplification applications?
It can be used in Class-A or AB amplifier stages where VCE remains > −5 V and IC stays below 100 mA, leveraging its fT = 80 MHz and hFE stability. However, its primary qualification and characterization focus is on switching operation-not small-signal linearity or noise performance.
Does BC806-16H-Q require a heatsink in typical 500 mA switching operation?
No external heatsink is required if mounted on standard FR4 with recommended solder footprint and ambient ≤ 70 °C. At full 500 mA, junction temperature rise is ~250 °C × 500 K/W = 125 K above ambient-well within the 175 °C limit only if ambient stays ≤ 50 °C. For sustained 500 mA at >70 °C ambient, use the enhanced thermal pad layout (Rth(j-a) = 363 K/W).
