Product details

Overview

BC806-16HR from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −80 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 100–250 at V_CE = −1 V and I_C = −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 BC806-16HR datasheet, BC806-16HR pinout, BC806-16HR application, or BC806-16HR equivalent, this page delivers verified electrical parameters, thermal derating behavior, saturation voltage under defined drive conditions, and validated alternative parts for design continuity and sourcing flexibility.

Technical Context

This PNP BJT supports high-voltage switching in off-board and distributed power rail applications, with guaranteed breakdown voltages of −80 V V_CEO and V_CBO, and low saturation performance: V_CE(sat) ≤ −400 mV at I_C = −500 mA and I_B = −50 mA. Its h_FE range (100–250) enables predictable base drive sizing across temperature.

Thermal design is supported by two distinct power dissipation ratings: 300 mW on standard FR4 footprint and 415 mW with 1 cm² collector pad, reflecting R_th(j-a) values of 500 K/W and 363 K/W respectively. The device is non-automotive qualified per Rev. 2 (2025), intended for industrial and commercial use only.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V - Maximum safe collector-emitter voltage with base open; defines upper limit for 48 V net switching margin.
I_C	−500 mA - Continuous DC collector current rating at 25 °C ambient; usable up to 175 °C junction with derating.
h_FE	100–250 - DC current gain at V_CE = −1 V, I_C = −100 mA; determines base resistor selection for reliable saturation.
V_CE(sat)	≤ −400 mV - Collector-emitter saturation voltage at I_C = −500 mA, I_B = −50 mA; ensures <0.2 W conduction loss at full load.
T_j(max)	175 °C - Maximum junction temperature; enables operation in high-ambient environments like engine bays or enclosed power modules.
C_c	5 pF - Collector capacitance at V_CB = −10 V; limits high-frequency switching speed and affects EMI filtering requirements.
R_th(j-a)	500 K/W - Junction-to-ambient thermal resistance on standard FR4 PCB; informs heatsinking needs for sustained 300 mW dissipation.

Pinout & Package

SOT23 (TO-236AB) plastic surface-mount package with 3 leads, 1.3 mm max height, and standardized reflow/wave solder footprints per Figures 29–30 in the datasheet.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires current-limited drive to achieve target I_C; polarity-sensitive for PNP turn-on (negative bias relative to emitter).
2	Emitter (E)	Current source terminal; connected to higher potential rail in high-side switch configurations; must be referenced to system ground or supply return.
3	Collector (C)	Load connection terminal; sinks current from external load to emitter; thermally coupled to PCB pad for power dissipation management.

Key Features

Feature	Design Value
High-voltage capability	−80 V V_CEO/V_CBO enables direct interface with 48 V automotive and industrial bus systems without level-shifting.
High-temperature operation	Rated to 175 °C T_j supports deployment in under-hood, motor-drive, and power-conversion environments with minimal derating.
Two h_FE grades	BC806-16H (100–250) and BC806-25H (160–400) allow precise base drive optimization for either efficiency or noise immunity.
Low V_CE(sat)	≤ −400 mV at full 500 mA load reduces conduction losses and self-heating in continuous-duty switching applications.
Standardized SOT23 footprint	Compatible with automated pick-and-place and reflow processes; supports high-volume manufacturing with proven yield and reliability.

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
BC807-16H	Same SOT23 package and h_FE grade (100–250), but NPN polarity; V_CEO = 45 V, I_C = 500 mA.	Requires circuit topology change from high-side to low-side switching; unsuitable for 48 V rail where emitter is tied to battery positive.	Select only when redesign permits NPN placement and lower voltage margin is acceptable.
MMBT3906	Same PNP polarity, SOT23 package, but lower V_CEO = −40 V and h_FE = 100–300; T_j(max) = 150 °C.	Limited to ≤36 V systems; derates faster above 100 °C ambient due to lower thermal ceiling and power handling.	Acceptable for cost-sensitive 24 V commercial designs where 48 V transient immunity is not required.

Compared with BC806-16HR, BC807-16H offers identical gain but reversed polarity and reduced voltage rating, while MMBT3906 trades 40 V headroom and 25 °C thermal margin for broader legacy availability-neither is drop-in compatible without schematic or layout revision.

FAQ

Is BC806-16HR qualified for automotive applications?

No. Per Revision 2 (2025), BC806-16HR is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and is intended for industrial and commercial use only. For automotive designs, Nexperia offers separate −Q qualified variants such as BC806-16Q.

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 continuous operation requires limiting I_B to ensure junction temperature stays within 175 °C. At I_C = −500 mA and h_FE = 100, I_B = −5 mA is sufficient for saturation; typical design uses −10 mA to guarantee margin.

How does thermal performance change with PCB copper area?

R_th(j-a) improves from 500 K/W (standard footprint) to 363 K/W when the collector pad is enlarged to 1 cm² on single-sided FR4. This 27 % reduction in thermal resistance allows 38 % more power dissipation (415 mW vs. 300 mW) before reaching T_j = 175 °C at 25 °C ambient.

Can BC806-16HR replace BC806-25H in existing designs?

Yes, electrically-both share identical voltage, current, and package ratings-but h_FE is lower (100–250 vs. 160–400). Circuits relying on minimum h_FE > 160 may require base resistor adjustment to maintain saturation; verify V_CE(sat) under worst-case I_C and temperature conditions.
