Product details

Overview

BC856BMYL from Nexperia is a PNP general-purpose bipolar junction transistor in a DFN1006-3 (SOT883) leadless ultra-small surface-mount package, rated for −60 V V_CEO, −100 mA I_C, and DC current gain (h_FE) of 220–475 at −5 V V_CE and −2 mA I_C; it serves as a compact switching and amplification device in space-constrained mobile and automotive signal paths.

For engineers reviewing the BC856BMYL datasheet, BC856BMYL pinout, BC856BMYL application, or BC856BMYL equivalent, this page delivers verified package mapping, AEC-Q101 qualification status, thermal resistance (R_th(j-a) = 500 K/W), saturation voltage (V_CEsat ≤ −400 mV at −100 mA/−5 mA), and marking code (J2) to support rapid PCB layout, reliability validation, and automotive-grade BOM selection.

Technical Context

This PNP transistor operates with open-base collector-emitter breakdown at −60 V and open-emitter collector-base breakdown at −80 V, supporting robust voltage margin in low-power bias networks. Its h_FE remains stable across −55 °C to +150 °C ambient, enabling consistent gain in automotive cabin and engine-control modules.

The device exhibits V_BEsat ≤ −850 mV at −100 mA/−5 mA and transition frequency f_T ≥ 100 MHz at −5 V V_CE/−10 mA I_C, confirming suitability for medium-speed digital switching and analog pre-amplification where bandwidth and low-saturation loss are jointly critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage with base open; defines headroom for PNP switch operation in 24 V automotive rails.
I_C	−100 mA continuous: Absolute maximum DC collector current; sets upper bound for load-driving capability in discrete logic interfaces.
h_FE	220–475 at −5 V V_CE, −2 mA I_C: Confirmed DC current gain range; enables predictable base drive sizing for reliable saturation in switching circuits.
V_CEsat	≤ −400 mV at −100 mA I_C, −5 mA I_B: Low saturation voltage ensures minimal power loss and heat generation during on-state conduction.
R_th(j-a)	500 K/W on FR4 PCB: Thermal resistance value used to calculate junction temperature rise under real board-mount conditions.
f_T	≥ 100 MHz at −5 V V_CE, −10 mA I_C: Transition frequency confirms usable bandwidth for audio-frequency amplification and fast digital edge control.

Pinout & Package

BC856BMYL uses the DFN1006-3 (SOT883) leadless ultra-small plastic package: 0.62 mm × 0.55 mm footprint, 0.30 mm height, three solderable terminals on bottom side only, requiring reflow-compatible stencil design per Figure 8 in the datasheet.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on.
2	Emitter (E)	Current source terminal in PNP configuration; connected to higher potential rail in common-emitter switching layouts.
3	Collector (C)	Current sink terminal; carries load current to ground or lower-potential node when transistor is saturated.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine control units and body electronics per stress-test requirements.
Leadless DFN1006-3 package	0.62 mm × 0.55 mm footprint reduces PCB area by >60% vs. SOT23 while maintaining comparable power dissipation (250 mW).
V_BEsat ≤ −850 mV	Ensures sufficient base-emitter overdrive at high collector currents, reducing required base drive power in battery-sensitive designs.
ICBO ≤ −15 nA at 25 °C	Ultra-low collector-base leakage supports stable biasing in high-impedance sensor interface circuits over temperature.

Applications

Automotive Cabin Control

Portable Audio Amplifier Stage

Use Scenario: Biasing and current sourcing in Class-A headphone amplifier output stages within Bluetooth earbuds.

IC Role / Device Role / Timing Role: Discrete PNP active load and emitter-follower buffer; leverages h_FE stability and low V_CEsat for linearity and efficiency.

Use Value: 100 MHz f_T and 4.5 pF C_E enable clean audio-band response without high-frequency peaking or instability.

Smartphone Power Sequencing

Industrial Sensor Signal Conditioning

Use Scenario: Enabling/disabling auxiliary power rails (e.g., camera module, NFC) during boot and sleep transitions.

IC Role / Device Role / Timing Role: Low-leakage PNP high-side switch controlled by base driver IC; operates in linear and saturated regions during ramp-up.

Use Value: IEBO ≤ −100 nA and T_amb range of −55 °C to +150 °C ensure reliable sequencing across environmental extremes.

Use Scenario: Level-shifting and current buffering between low-voltage microcontrollers (1.8–3.3 V) and 5 V analog sensors.

IC Role / Device Role / Timing Role: PNP emitter follower providing impedance transformation and rail-to-rail signal translation without inversion.

Use Value: V_BE = −600 to −750 mV at −2 mA I_C enables precise bias point setting for offset-critical instrumentation paths.

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
BC856BL	Same DFN1006-3 package but h_FE range 110–220 - lower gain bin	Suitable where reduced base drive current is acceptable and tighter gain tolerance not required	Select when cost sensitivity outweighs need for high h_FE consistency in non-critical bias networks
BC846BM	NPN complement; identical package, ratings, and AEC-Q101 qualification but opposite polarity	Used in low-side switching or NPN-based amplifier topologies where PNP is not electrically suitable	Choose only when circuit topology mandates NPN configuration - not a functional drop-in replacement

Compared with BC856BMYL, BC856BL offers lower h_FE at identical package and voltage rating, simplifying base resistor selection in fixed-gain designs; BC846BM provides matched performance in NPN form but requires schematic-level polarity reversal and cannot replace BC856BMYL without redesign.

FAQ

What is the marking code for BC856BMYL?

The BC856BMYL is marked with the code "J2" on its top surface, visible under magnification. This two-character marking aligns with Nexperia's standardized coding for the BC856BM series in DFN1006-3 packages and is used for traceability and visual identification during automated optical inspection (AOI) and manual assembly verification.

Is BC856BMYL suitable for automotive applications?

Yes - BC856BMYL is fully qualified to AEC-Q101 standards for discrete semiconductors, having passed stress tests including HTGB, AC/DC life test, and temperature cycling. It is approved for use in automotive cabin electronics, body control modules, and infotainment subsystems operating within −55 °C to +150 °C ambient ranges.

How does BC856BMYL's thermal performance compare to SOT23-packaged equivalents?

BC856BMYL's R_th(j-a) is 500 K/W on FR4 PCB - identical to typical SOT23-3 devices under the same mounting conditions. Despite its smaller DFN1006-3 footprint, its thermal resistance is maintained via optimized copper pad layout and solder joint geometry, enabling equivalent 250 mW power dissipation capability.

Can BC856BMYL be used in linear amplifier configurations?

Yes - BC856BMYL supports linear operation with verified V_BE = −600 to −750 mV at −2 mA I_C, NF = 10 dB at 1 kHz, and f_T ≥ 100 MHz. Its h_FE stability across temperature and low C_C (2.5 pF) make it viable for low-noise pre-amplifier stages and emitter-follower buffers in portable audio and sensor front-ends.
