Product details

Overview

BC806-16WF from Nexperia is a PNP general-purpose transistor in SOT323 (SC-70) package, rated for −80 V V_CEO, −500 mA I_C, and 100–250 h_FE at −100 mA/−1 V. It serves as a compact, AEC-Q101-qualified switching or amplification device in space-constrained automotive and industrial control circuits.

For engineers reviewing the BC806-16WF datasheet, BC806-16WF pinout, BC806-16WF application, or BC806-16WF equivalent, this page delivers verified electrical parameters, thermal derating behavior, junction-to-ambient resistance, saturation voltage under load, and automotive-grade reliability context - all critical for discrete BJT selection in 48 V board nets and low-power logic interface stages.

Technical Context

This PNP bipolar junction transistor operates with open-base collector-emitter breakdown of −80 V and emitter-base breakdown of −8 V, supporting robust operation in negative-rail switching topologies. Its pulsed peak collector current reaches −1 A (t_p ≤ 1 ms), enabling brief overload tolerance in relay drivers and LED sink stages.

The device exhibits temperature-stable DC current gain across −55 °C to +150 °C ambient, with h_FE maintaining ≥100 at −500 mA/−2 V and ≥30 at high-current saturation conditions. Thermal resistance R_th(j-a) is 625 K/W on standard FR4 PCB and improves to 431 K/W with 1 cm² collector pad - directly informing layout-driven power handling limits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V: Maximum safe collector-emitter voltage with base open; defines rail compatibility in −48 V systems.
I_C	−500 mA continuous: Sustained current-handling capability for signal-level switching and small-signal amplification.
h_FE	100–250 at −100 mA/−1 V: Predictable current amplification range enabling stable bias design in linear and saturated modes.
V_CE(sat)	≤ −400 mV at −500 mA/−50 mA: Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switch applications.
P_tot	290 mW at T_amb ≤ 25 °C: Absolute maximum dissipation on FR4 PCB with optimized collector pad; derates linearly above 25 °C.
R_th(j-a)	625 K/W (standard footprint): Junction-to-ambient thermal resistance determines required board copper area for thermal management.

Pinout & Package

SOT323 (SC-70) plastic surface-mount package: 1.35 mm × 2.2 mm footprint, 0.95 mm height, 3-terminal configuration with gull-wing leads. Optimized for reflow soldering per IPC-7095 guidelines.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires series resistor to limit I_B ≤ −200 mA peak and ensure reliable turn-on at target I_C.
2	Emitter (E)	Common reference terminal tied to negative rail; carries full I_C + I_B; must connect to low-impedance ground plane.
3	Collector (C)	Output current path; connects to load between negative supply and collector; requires thermal pad for >150 mW operation.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive temperature cycling, humidity, and mechanical stress - suitable for under-hood and body-control modules.
Two h_FE bins (16W/25W)	BC806-16WF offers 100–250 h_FE for predictable gain control; avoids overdesign in feedback-critical amplifier stages.
−80 V V_CEO rating	Supports direct use in 48 V automotive board nets without external clamping, reducing component count in power distribution nodes.
Low V_CE(sat)	≤ −400 mV at −500 mA enables <100 mW conduction loss in saturated switching - critical for thermally constrained PCB layouts.

Applications

Automotive Body Control

Industrial Sensor Interface

Use Scenario: Driving resistive loads (e.g., door lock solenoids, HVAC actuators) from microcontroller GPIO pins in 48 V vehicle architectures.

IC Role / Device Role / Timing Role: PNP switch sinking current from load to ground; provides level-shifted, rail-referenced control with fast turn-off via base pull-up.

Use Value: −80 V rating eliminates need for external TVS; AEC-Q101 qualification ensures long-term reliability in vibration-prone environments.

Use Scenario: Amplifying low-level analog signals from pressure or temperature sensors before ADC sampling in PLC I/O modules.

IC Role / Device Role / Timing Role: Small-signal common-emitter amplifier with fixed bias network; sets gain and output impedance for sensor signal conditioning.

Use Value: Stable h_FE (100–250) across −40 °C to +125 °C enables consistent gain calibration without software compensation.

LED Indicator Driver

Power Supply Enable Switch

Use Scenario: Controlling multi-color status LEDs on front-panel displays in medical equipment and test instruments.

IC Role / Device Role / Timing Role: Low-side current sink switching LED anodes tied to positive rails; handles up to −500 mA per channel.

Use Value: ≤ −400 mV V_CE(sat) at full current ensures >95% power efficiency and minimal self-heating in dense LED arrays.

Use Scenario: Enabling/disabling auxiliary 3.3 V or 5 V LDO outputs in embedded computing platforms using processor-controlled enable lines.

IC Role / Device Role / Timing Role: High-side switch controller (driving N-channel MOSFET gate) or direct low-side enable path for regulator GND return.

Use Value: −1 A pulsed I_CM supports inrush current limiting during power-up sequencing without latch-up or thermal shutdown.

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
BC807-16W	NPN complement with +80 V V_CEO, +500 mA I_C, same h_FE bin; not electrically interchangeable due to polarity reversal.	Used in high-side sourcing configurations where NPN topology matches system grounding scheme.	Select only when circuit topology requires NPN polarity and complementary gain matching is needed.
ZTX753	Higher V_CEO (+100 V), higher I_C (+1 A), TO-92 package; h_FE 100–300 but lacks AEC-Q101 qualification.	Suitable for non-automotive industrial power supplies requiring higher voltage margin and through-hole assembly.	Choose for cost-sensitive non-automotive designs needing extended voltage headroom and no SMT constraints.

Compared with BC806-16WF, BC807-16W enables NPN-based high-side drive but cannot replace it directly in PNP circuits, while ZTX753 trades automotive qualification for higher voltage/current ratings and through-hole mounting - making BC806-16WF the optimal choice for space-limited, AEC-compliant SMT designs.

FAQ

What is the maximum allowable base current for BC806-16WF?

The absolute maximum pulsed base current is −200 mA (t_p ≤ 1 ms), per IEC 60134 limiting values. For continuous operation, base current should be limited to maintain I_C ≤ −500 mA and junction temperature below 150 °C - typically requiring I_B ≤ −50 mA at saturation to ensure reliable turn-on without thermal runaway.

Is BC806-16WF suitable for linear amplification applications?

Yes - its DC current gain (100–250) and low distortion characteristics at V_CE = −1 V make it suitable for Class-A audio preamplifiers and sensor signal conditioning. However, thermal derating must be applied: at 85 °C ambient, maximum continuous power drops to ~180 mW, limiting usable output swing in high-gain stages.

How does the SOT323 package affect thermal performance?

The SOT323 package delivers 625 K/W R_th(j-a) on standard FR4 PCB, rising to 431 K/W with a 1 cm² copper pad under the collector lead. This means at 25 °C ambient and 200 mW dissipation, junction temperature reaches ~150 °C without the pad - confirming that thermal pad implementation is mandatory for sustained >150 mW operation.

Does BC806-16WF require external protection in automotive 48 V systems?

No external transient protection is required for nominal 48 V operation due to its −80 V V_CEO rating, which exceeds ISO 7637-2 Pulse 1 (−100 V) and Pulse 2a (−150 V) requirements. However, for systems exposed to load-dump events (>60 V), a parallel TVS diode remains recommended to clamp transients beyond −80 V.
