Product details

Overview

BC807K-40VL from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 (TO-236AB) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 250–600 at V_CE = −1 V and I_C = −100 mA. It delivers low V_CE(sat) (−700 mV max at I_C = −500 mA / I_B = −50 mA) and is AEC-Q101 qualified for automotive-grade reliability. It serves as a compact, high-gain switching or linear amplification device in power management and signal conditioning circuits.

For engineers reviewing the BC807K-40VL datasheet, BC807K-40VL pinout, BC807K-40VL application, or BC807K-40VL equivalent, this page provides verified technical context, validated pin functions, real-world use cases in automotive and industrial systems, and confirmed alternative parts with documented parameter differences.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with defined absolute maximum ratings: −45 V collector-emitter voltage, −500 mA continuous collector current, and 150 °C junction temperature. Its h_FE spread (250–600) enables precise biasing in analog amplifiers and robust switching in digital logic interfaces.

Thermal performance varies by PCB layout: R_th(j-a) ranges from 157 K/W (4-layer copper, 1 cm² collector pad) to 358 K/W (single-sided FR4, standard footprint). Safe operating area (SOA) curves confirm stable operation up to 1 A peak current for 1 ms pulses at V_CE ≤ −10 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum allowable collector-emitter voltage before breakdown; defines safe voltage headroom in high-side switch configurations.
I_C	−500 mA - Continuous DC collector current rating; supports load switching up to ~500 mA in compact SMT designs.
h_FE	250–600 @ V_CE = −1 V, I_C = −100 mA - High and tightly binned current gain enables stable biasing with minimal base drive current.
V_CE(sat)	−700 mV max @ I_C = −500 mA, I_B = −50 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications.
P_tot	800 mW @ T_amb ≤ 25 °C on 4-layer FR4 with 1 cm² collector pad - Enables higher power handling than standard SOT23 variants when thermally optimized.
f_T	80 MHz @ V_CE = −5 V, I_C = −10 mA - Supports high-frequency small-signal amplification up to mid-VHF range.
AEC-Q101	Qualified - Meets automotive stress test requirements for temperature cycling, HTRB, and ESD, enabling use in under-hood and body-control modules.

Pinout & Package

SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.9 mm × 1.3 mm footprint, 1.1 mm height, and gull-wing lead form for reflow compatibility.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input terminal; requires ~50 mA base drive for full saturation at 500 mA collector load.
2	Emitter (E)	Common reference terminal for PNP operation; connected to higher potential (e.g., V_CC) in high-side switch topologies.
3	Collector (C)	Output current path; sinks load current to ground or lower-potential node; thermally coupled to PCB pad for enhanced power dissipation.

Key Features

Feature	Design Value
Three h_FE bins	BC807K-16 (100–250), BC807K-25 (160–400), BC807K-40 (250–600) - Enables design-specific gain selection without circuit redesign.
AEC-Q101 qualification	Validated for automotive environments including −40 °C to +125 °C ambient operation and 1000-cycle temperature cycling - eliminates need for additional qualification testing.
High P_tot capability	Up to 800 mW on optimized 4-layer PCB - doubles thermal margin vs. legacy SOT23 transistors with same footprint.
Low V_BE(sat)	−1.2 V max @ I_C = −500 mA, I_B = −50 mA - Reduces base drive power and simplifies driver stage design in high-current switches.

Applications

Automotive Body Control Module

Industrial Sensor Signal Conditioning

Use Scenario: Driving LED indicators, relays, and solenoids in door modules and lighting control units.

IC Role / Device Role / Timing Role: PNP high-side switch controlling 12 V loads with microcontroller-compatible base drive.

Use Value: −45 V V_CEO withstands automotive load-dump transients; AEC-Q101 ensures long-term reliability in vibration-prone environments.

Use Scenario: Amplifying low-level analog outputs from pressure or temperature sensors before ADC sampling.

IC Role / Device Role / Timing Role: Linear amplifier configured in common-emitter topology with stable h_FE binning.

Use Value: 250–600 h_FE range allows predictable gain calibration; low V_CE(sat) preserves dynamic range in rail-to-rail sensor interfaces.

Consumer Power Management

Medical Diagnostic Equipment

Use Scenario: Enabling/disabling auxiliary power rails in portable medical monitors and handheld devices.

IC Role / Device Role / Timing Role: Low-power PNP pass transistor in discrete LDO-like regulators or enable logic.

Use Value: SOT23 footprint saves board space; 800 mW P_tot supports 300–500 mA loads without heatsinking.

Use Scenario: Isolating and buffering analog front-end signals in ECG/EEG acquisition circuits.

IC Role / Device Role / Timing Role: Low-noise, low-capacitance (C_e = 37 pF) PNP amplifier stage minimizing signal distortion.

Use Value: 37 pF emitter capacitance at V_EB = −0.5 V reduces high-frequency roll-off; AEC-Q101 grade implies high process consistency critical for diagnostic accuracy.

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
BC807-40	Same electrical specs but non-AEC-Q101; SOT23 package with identical pinout and marking (HC%); no automotive qualification documentation.	Not suitable for automotive production; acceptable for industrial or consumer prototypes where qualification isn't mandated.	Select BC807K-40VL when AEC-Q101 compliance is required; choose BC807-40 only for cost-sensitive non-automotive designs.
MMBT3906LT1G	Lower h_FE (100–300), same V_CEO (−40 V), slightly higher V_CE(sat) (−800 mV), and no AEC-Q101 certification.	Limited to non-automotive signal switching; insufficient gain stability for precision analog amplification.	Use MMBT3906LT1G only if footprint compatibility is critical and automotive qualification is unnecessary; avoid where h_FE > 250 is required.

Compared with BC807-40 and MMBT3906LT1G, BC807K-40VL uniquely combines AEC-Q101 qualification, 250–600 h_FE binning, and 800 mW thermal capability-making it the only option among the three qualified for automotive production and high-reliability industrial signal paths.

FAQ

What is the maximum continuous collector current for BC807K-40VL?

The maximum continuous collector current (I_C) is −500 mA at T_amb ≤ 25 °C on a 4-layer FR4 PCB with optimized thermal pad. Derating applies above 25 °C ambient per Figure 1; at 85 °C, usable I_C drops to approximately −350 mA due to thermal limits.

Is BC807K-40VL pin-compatible with BC807-40?

Yes-both use identical SOT23 (TO-236AB) package with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. Mechanical dimensions, solder footprint (Figure 44), and marking layout match exactly; only qualification status and h_FE binning differ.

What does the 'K' suffix in BC807K-40VL signify?

The 'K' denotes Nexperia's automotive-qualified variant: it indicates AEC-Q101 qualification, tighter h_FE binning (250–600), and enhanced process controls for automotive production. The 'VL' suffix specifies tape-and-reel packaging per EIA-481-D standards with 3000 units per reel.

Can BC807K-40VL replace BC807K-25 in an existing design?

Yes, with verification: both share identical V_CEO, I_C, and package, but BC807K-40VL offers higher minimum h_FE (250 vs. 160). This may reduce base drive requirements or improve gain stability-but verify saturation behavior at target I_C/I_B ratios to avoid overdrive or unintended linear-region operation.
