Product details
Overview
BC806-25HVL from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 package, rated for −80 V VCEO, −500 mA IC, and DC current gain (hFE) of 160–400 at VCE = −1 V and IC = −100 mA. It operates up to 175 °C junction temperature and serves as a robust switching or linear amplification device in 48 V automotive board nets and industrial control circuits.
For engineers reviewing the BC806-25HVL datasheet, BC806-25HVL pinout, BC806-25HVL application, or BC806-25HVL equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternative transistors for high-voltage PNP switching designs requiring stable hFE across temperature and load conditions.
Technical Context
This PNP BJT features a planar epitaxial die structure optimized for high-voltage blocking (−80 V VCEO/VCBO) and reliable saturation performance with VCE(sat) ≤ −400 mV at IC = −500 mA and IB = −50 mA. Its hFE range (160–400) supports consistent biasing in both linear and saturated switching modes.
Thermal design is enabled by two defined mounting configurations: standard SOT23 footprint (Rth(j-a) = 500 K/W) and enhanced collector pad (Rth(j-a) = 363 K/W), supporting operation from −55 °C to +175 °C ambient with pulsed ICM up to −1 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Maximum safe collector-emitter voltage with base open; enables use in 48 V automotive systems with margin. |
| IC | −500 mA - Continuous DC collector current rating; supports medium-power switching loads without forced cooling. |
| hFE | 160–400 - DC current gain at VCE = −1 V, IC = −100 mA; ensures predictable base drive requirements in amplifier and switch designs. |
| VCE(sat) | ≤ −400 mV - Collector-emitter saturation voltage at IC = −500 mA, IB = −50 mA; minimizes conduction loss in high-current on-state operation. |
| Tj(max) | +175 °C - Maximum junction temperature; allows deployment in under-hood automotive or high-ambient industrial environments. |
| fT | 80 MHz - Transition frequency at VCE = −5 V, IC = −50 mA; supports audio-frequency and low-speed digital switching applications. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads; 1.3 mm × 2.9 mm footprint, 1.1 mm height, and tin-plated terminations compatible with standard reflow and wave soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control terminal; requires negative bias relative to emitter to forward-bias base-emitter junction and enable conduction. |
| 2 | Emitter (E) | Current source terminal in PNP configuration; connected to higher potential rail (e.g., +48 V) in high-side switch topologies. |
| 3 | Collector (C) | Current sink terminal; routed to load and ground reference; thermally coupled to PCB pad for enhanced power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | −80 V VCEO and VCBO - Enables direct interface with 48 V battery rails and transient-tolerant industrial supplies. |
| High-temperature operation | Rated to +175 °C Tj - Supports under-hood automotive and high-ambient industrial deployments without derating. |
| Two hFE grades | BC806-25H offers 160–400 hFE - Reduces base drive variability in production batches versus lower-gain BC806-16H (100–250). |
| Pulsed current capability | −1 A ICM (tp ≤ 1 ms) - Allows short-duration surge handling in motor drive or solenoid control applications. |
Applications
| Automotive 48 V Board Net | Industrial Power Sequencing |
|---|---|
|
Use Scenario: Switching power distribution in 48 V mild-hybrid vehicle subsystems (e.g., HVAC actuators, ADAS sensors). IC Role / Device Role / Timing Role: High-side PNP switch controlling load connection to 48 V rail; driven by microcontroller GPIO via base resistor. Use Value: −80 V VCEO provides 20 V margin over nominal 48 V bus, while −500 mA IC supports typical actuator coil currents. |
Use Scenario: Enabling/disabling auxiliary power rails during system boot-up or fault recovery in PLC backplanes. IC Role / Device Role / Timing Role: Discrete PNP switch in discrete power-OR or sequencing circuit; used where integrated PMICs lack required voltage or current rating. Use Value: Stable hFE across −55 °C to +125 °C ambient ensures reliable turn-on timing without active feedback compensation. |
| Linear Voltage Regulation | Signal-Level Amplification |
|
Use Scenario: Pass element in low-noise, adjustable linear regulator for analog sensor supply (e.g., precision current loops). IC Role / Device Role / Timing Role: PNP emitter-follower configured as series pass transistor; base driven by error amplifier output. Use Value: Low VCE(sat) (≤ −400 mV) minimizes dropout voltage, while 80 MHz fT supports loop stability up to ~100 kHz bandwidth. |
Use Scenario: Small-signal preamplifier stage for thermocouple or bridge sensor outputs in data acquisition modules. IC Role / Device Role / Timing Role: Common-emitter amplifier biased in active region; configured for fixed-gain, low-distortion signal conditioning. Use Value: Tight hFE spread (160–400) and low Cc (5 pF) ensure predictable gain and minimal high-frequency roll-off in DC–100 kHz band. |
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 |
|---|---|---|---|
| BC806-16H | Lower hFE range (100–250) at same test conditions; otherwise identical VCEO, IC, and package. | Suitable where reduced base drive sensitivity is acceptable and tighter hFE tolerance is not required. | Select when cost optimization is prioritized and circuit tolerates wider base current variation. |
| MMBT3906LT1G | Same SOT23 package but lower VCEO (−40 V), lower IC (−200 mA), and hFE 100–300; RoHS-compliant, automotive-grade option available. | Limited to ≤24 V systems; unsuitable for 48 V automotive net due to insufficient voltage margin. | Choose only for legacy 24 V designs or space-constrained consumer electronics where −40 V rating suffices. |
Compared with BC806-16H, BC806-25HVL provides higher and more consistent hFE for stable base drive in production; versus MMBT3906LT1G, it delivers critical −80 V rating and −500 mA current capacity essential for next-generation 48 V automotive and industrial power control.

FAQ
Is BC806-25HVL automotive-qualified?
No. Per Nexperia's revision history (Rev. 2, 30 September 2025), BC806H_SER is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is not warranted for safety-critical automotive use. For automotive applications, Nexperia offers separate −Q qualified variants such as BC806-25H-Q.
What is the maximum allowable power dissipation at 100 °C ambient?
At Tamb = 100 °C, the maximum power dissipation is 225 mW when mounted on an FR4 PCB with standard footprint (Rth(j-a) = 500 K/W). This is derived from the linear derating curve in Figure 1: Ptot = 300 mW − [(100 − 25) × 1 mW/°C] = 225 mW.
Can BC806-25HVL replace BC806-16H in existing designs?
Yes, BC806-25HVL is a direct drop-in replacement for BC806-16H in the same SOT23 package with identical pinout and absolute maximum ratings. Its higher hFE (160–400 vs. 100–250) may reduce required base drive current but does not affect voltage or thermal limits.
What is the emitter-base breakdown voltage (VEBO) specification?
VEBO is −8 V minimum at IE = −100 µA and Tamb = 25 °C. This defines the maximum reverse voltage permissible across the base-emitter junction before breakdown, critical for ensuring safe operation in circuits with negative base transients or ESD events.
