Product details

Overview

BC806-16WX from Nexperia is a PNP bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −80 V V_CEO, −500 mA I_C, and offering h_FE = 100–250 at V_CE = −1 V, I_C = −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 BC806-16WX datasheet, BC806-16WX pinout, BC806-16WX application, or BC806-16WX equivalent, this page delivers verified electrical parameters, thermal derating behavior, AEC-Q101 qualification status, and real-world use context for discrete PNP transistor selection in space-constrained, high-reliability designs.

Technical Context

This transistor operates as a current-controlled switch or linear amplifier with fixed polarity: base-emitter forward bias enables collector-emitter conduction, supporting active-region amplification or saturated switching. Its −80 V V_CEO rating supports operation across 48 V automotive supply rails with margin, while −500 mA continuous collector current accommodates medium-power load switching.

Thermal performance is defined by R_th(j-a) = 625 K/W on standard FR4 PCB and 431 K/W with 1 cm² collector pad - critical for sustained pulse operation up to 1 A peak (t_p ≤ 1 ms). AEC-Q101 qualification confirms suitability for automotive under-hood environments with T_amb from −55 °C to +150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V: Maximum safe collector-emitter voltage with open base; enables robust operation in 48 V automotive systems with transient margin.
I_C	−500 mA: Continuous DC collector current; supports medium-power switching in sensor interfaces and logic-level translators.
h_FE	100–250 at V_CE = −1 V, I_C = −100 mA: Predictable DC current gain for stable biasing in amplifier and switch driver circuits.
V_CE(sat)	≤ −400 mV at I_C = −500 mA, I_B = −50 mA: Low saturation voltage minimizes power loss and heating during switching.
P_tot	290 mW at T_amb ≤ 25 °C (with 1 cm² collector pad): Defines maximum steady-state power dissipation before thermal derating applies.
f_T	80 MHz at V_CE = −5 V, I_C = −50 mA: Supports high-speed switching up to ~10 MHz square-wave operation with adequate gain margin.

Pinout & Package

SOT323 (SC-70) is a 3-pin, surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm (L × W × H), optimized for high-density PCB layouts and reflow soldering per IPC-7095 guidelines.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal: Forward-biased relative to emitter to enable conduction; requires current-limited drive for predictable switching speed.
2	Emiter (E)	Current source terminal: Connected to higher potential in PNP configuration; forms common reference for base drive and load return path.
3	Collector (C)	Output terminal: Carries switched load current; thermally coupled to PCB pad to manage 290 mW dissipation under ambient conditions.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine control modules and body electronics per stress test requirements.
Two h_FE bins (16W/25W)	BC806-16WX offers 100–250 h_FE; enables precise gain matching in differential pairs or consistent switching thresholds across production lots.
High-voltage capability	−80 V V_CEO and V_CBO support operation in 48 V battery systems with ISO 7637-2 pulse margin and reverse-polarity protection circuits.
Low V_CE(sat)	≤ −400 mV at full rated current ensures <100 mW conduction loss, reducing thermal load in compact enclosures.

Applications

Automotive 48 V Board Net

Industrial Sensor Interface

Use Scenario: Switching of solenoid drivers and LED arrays in 48 V vehicle architectures with transient voltage spikes up to ±100 V.

IC Role / Device Role / Timing Role: PNP switch controlling ground-referenced loads via microcontroller GPIO with level-shifting base resistor network.

Use Value: −80 V rating provides 20 V margin against load-dump transients; AEC-Q101 qualification ensures reliability over 15-year vehicle lifetime.

Use Scenario: Amplifying low-level analog signals from RTDs or bridge sensors in programmable logic controllers (PLCs).

IC Role / Device Role / Timing Role: Linear-mode PNP amplifier stage providing current gain and impedance transformation before ADC input.

Use Value: Stable h_FE = 100–250 across −40 °C to +125 °C enables accurate gain calibration without temperature compensation circuitry.

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 same V_CEO (−45 V), I_C (500 mA), and h_FE bin; not polarity-compatible.	Requires circuit topology change (low-side vs. high-side switching); unsuitable for direct replacement in PNP-configured designs.	Select only when redesigning for NPN-based topology or complementary pair usage.
MMBT3906LT1G	Same SOT23 package but lower V_CEO (−40 V), lower I_C (−200 mA), and h_FE = 100–300; no AEC-Q101 qualification.	Limited to 24 V systems and non-automotive industrial use; insufficient voltage margin for 48 V board net compliance.	Acceptable for cost-sensitive consumer-grade 5–24 V applications where automotive qualification is unnecessary.

Compared with BC806-16WX, BC807-16W requires schematic revision due to opposite polarity, while MMBT3906LT1G sacrifices 40 V headroom and automotive reliability - making BC806-16WX the sole choice for AEC-compliant 48 V switching with validated thermal derating.

FAQ

Is BC806-16WX pin-compatible with BC806-25W?

Yes - both share identical SOT323 (SC-70) pinout (1: Base, 2: Emitter, 3: Collector) and mechanical footprint. The only difference is DC current gain: BC806-16WX has h_FE = 100–250, while BC806-25W offers 160–400. Substitution is electrically permissible if gain tolerance allows.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA (single pulse, t_p ≤ 1 ms), but for DC operation, base current must be limited to ensure I_C ≤ −500 mA and V_CE(sat) remains within spec. With h_FE ≥ 100, I_B ≤ −5 mA suffices for full conduction - typical design uses 5–10 kΩ base resistors from 3.3 V/5 V logic.

Does BC806-16WX support wave soldering?

Yes - Nexperia provides dedicated wave soldering footprint data (Fig. 14) with 3.65 mm × 2.1 mm land pattern and preferred transport direction. Thermal profile must respect max T_j = 150 °C and avoid exceeding 260 °C peak for >10 s; preheat ramp rate ≤ 3 °C/s is recommended.

How does thermal derating affect power handling above 25 °C?

At T_amb > 25 °C, total power dissipation linearly derates from 290 mW: slope is −2.32 mW/°C (based on 431 K/W R_th(j-a)). At 85 °C ambient, usable P_tot drops to ~155 mW - requiring reduced I_C or increased PCB copper area to maintain safe junction temperature.
