Product details
Overview
BC806-25VL from Nexperia is a PNP bipolar junction transistor (BJT) in SOT23 package, rated for -80 V VCEO, -500 mA IC, and 160–400 hFE at VCE = -1 V / IC = -100 mA. It serves as a general-purpose switching and amplification device in automotive 48 V board nets and industrial control signal stages.
For engineers reviewing the BC806-25VL datasheet, BC806-25VL pinout, BC806-25VL application, or BC806-25VL equivalent, this page delivers verified electrical parameters, thermal derating behavior, AEC-Q101 qualification status, and real-world use context for reliable component selection in high-reliability discrete designs.
Technical Context
The BC806-25VL operates as a silicon PNP BJT with open-base collector-emitter breakdown voltage of -80 V and peak pulsed collector current capability of -1 A. Its DC current gain range (160–400) targets mid-to-high gain switching applications where precise base drive control and stable gain across temperature are required.
Thermal resistance Rth(j-a) is 363 K/W when mounted on FR4 PCB with 1 cm² collector pad, enabling sustained operation up to 150 °C junction temperature. The device meets AEC-Q101 stress test requirements for automotive discrete semiconductors, confirming suitability for under-hood and chassis-mounted electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration |
| IC | -500 mA - Continuous DC collector current rating at Tamb ≤ 25 °C |
| hFE | 160–400 - DC current gain at VCE = -1 V, IC = -100 mA, defining base drive efficiency |
| VCE(sat) | -400 mV - Collector-emitter saturation voltage at IC = -500 mA, IB = -50 mA, indicating low conduction loss |
| Ptot | 345 mW - Total power dissipation limit on FR4 PCB with 1 cm² collector pad, governing thermal design margin |
| Tj(max) | 150 °C - Absolute maximum junction temperature, constraining ambient and layout thermal management |
| AEC-Q101 | Qualified - Validated per Automotive Electronics Council stress test standard for discrete semiconductors |
Pinout & Package
SOT23 (TO-236AB) surface-mount plastic package: 3-pin, small-outline, lead-free, RoHS-compliant. Dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H), with 0.95 mm pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | Emitter (E) | Current source terminal in PNP operation; connected to higher potential rail in typical high-side switch configurations |
| 3 | Collector (C) | Current sink terminal; carries load current to ground or lower-potential node when transistor is saturated |
Key Features

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 |
|---|---|---|---|
| BC806-16VL | Lower hFE range (100–250) and same VCEO/IC ratings | Better suited for high-speed switching where lower gain reduces storage time and improves turn-off response | Select when faster switching speed is prioritized over base current efficiency |
| BC856B | Same SOT23 package but NPN polarity; VCEO = -65 V, hFE = 220–475 | Requires inverted control logic and different biasing; not drop-in compatible for high-side PNP roles | Choose only for low-side switching or complementary pair designs where NPN topology is mandated |
Compared with BC806-16VL and BC856B, the BC806-25VL offers the highest guaranteed hFE among SOT23 PNP transistors in its voltage class, reducing base drive burden in space-constrained automotive modules without sacrificing ruggedness or thermal performance.

FAQ
Is BC806-25VL pin-compatible with BC806-16VL?
Yes - both share identical SOT23 (TO-236AB) package and pinout (1: Base, 2: Emitter, 3: Collector). They differ only in hFE binning, allowing direct substitution where gain tolerance permits. No layout or footprint changes are needed.
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, base current must be limited to ensure IC ≤ -500 mA and junction temperature remains ≤ 150 °C. At IC = -500 mA and hFE = 160, IB ≈ -3.1 mA is sufficient.
Does BC806-25VL support wave soldering?
Yes - Nexperia provides validated wave soldering footprints (Fig. 14) and thermal profiles. Recommended process uses preheat ≤ 100 °C, peak temperature ≤ 260 °C, and contact time ≤ 5 seconds. Solder mask-defined pads and proper conveyor orientation are critical for void-free joints.
How does thermal derating affect power handling at 85 °C ambient?
At Tamb = 85 °C, the 345 mW Ptot rating derates linearly per Fig. 1: approximately 220 mW maximum dissipation is allowed. This corresponds to ~450 mA IC at VCE(sat) = -400 mV, assuming no additional heatsinking beyond the standard FR4 pad.
