Product details

Overview

BC807K-25VL 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 160–400 at V_CE = −1 V and I_C = −100 mA. It delivers −700 mV V_CE(sat) at I_C = −500 mA / I_B = −50 mA and is AEC-Q101 qualified for automotive-grade reliability. It serves as a compact, robust switch or amplifier in low-voltage power control circuits such as LED drivers and load switching in body electronics.

For engineers reviewing the BC807K-25VL datasheet, BC807K-25VL pinout, BC807K-25VL application, or BC807K-25VL equivalent, this page provides verified electrical parameters, thermal derating curves, SOT23 pin mapping, AEC-Q101 qualification status, and direct alternatives with documented h_FE and saturation voltage differences.

Technical Context

The BC807K-25VL operates as a silicon PNP BJT with fixed emitter-base and collector-base junctions optimized for linear amplification and saturated switching. Its h_FE binning (160–400) enables predictable current control across industrial temperature range (−55 °C to +150 °C), and its −5 V V_EBO rating supports safe biasing in common-emitter configurations with moderate base drive.

Thermal performance is defined by R_th(j-a) values ranging from 157 K/W (4-layer PCB, 1 cm² collector pad) to 358 K/W (single-sided FR4), directly linking layout-dependent power handling to ambient conditions. Safe operating area (SOA) curves confirm stable pulsed operation up to 1 A peak with t_p ≤ 1 ms under specified mounting conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum allowable collector-emitter voltage with base open; defines safe blocking capability in switching applications.
I_C	−500 mA - Continuous DC collector current limit; sets maximum steady-state load drive capacity.
h_FE	160–400 at V_CE = −1 V, I_C = −100 mA - Confirmed DC current gain range enabling precise base resistor selection for target switching thresholds.
V_CE(sat)	−700 mV max at I_C = −500 mA, I_B = −50 mA - Verified saturation voltage defining conduction loss and heat generation during on-state operation.
P_tot	800 mW at T_amb ≤ 25 °C on 4-layer FR4 with 1 cm² collector pad - Absolute maximum dissipation under optimal board-level thermal management.
f_T	80 MHz at V_CE = −5 V, I_C = −10 mA - Transition frequency confirming usable bandwidth for audio-frequency amplification and fast-switching control.

Pinout & Package

SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, small-outline, lead-free, RoHS-compliant. Dimensions: 2.9 mm × 1.3 mm × 1.0 mm (L × W × H); standard footprint per Figure 44 (reflow) and Figure 45 (wave).

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires current-limited drive to achieve specified I_C/I_B ratio and avoid thermal runaway.
2	Emitter (E)	Current source node in PNP configuration; connected to higher potential rail; must be routed with low-inductance path for switching stability.
3	Collector (C)	Output current sink node; thermally coupled to PCB copper; requires ≥1 cm² copper pour on 4-layer boards to sustain 800 mW dissipation.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including body control modules and lighting systems per stress test requirements for discrete semiconductors.
Three h_FE bins	BC807K-25 offers mid-range gain (160–400), balancing switching speed and drive sensitivity-ideal for designs requiring tighter I_B tolerance than BC807K-16 but lower gain variation than BC807K-40.
High P_tot capability	800 mW rating on optimized 4-layer PCB enables higher continuous current vs. legacy SOT23 transistors limited to 350–500 mW.
Low V_CE(sat)	−700 mV max ensures <125 mW conduction loss at 500 mA, reducing thermal load in space-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 vehicle body electronics modules.

IC Role / Device Role / Timing Role: PNP switch configured in common-emitter topology, sinking current from 12 V supply through load to ground.

Use Value: AEC-Q101 qualification ensures operational reliability over −40 °C to +125 °C ambient; −45 V V_CEO withstands load-dump transients up to ISO 7637-2 Pulse 5a.

Use Scenario: Level-shifting and buffering analog sensor outputs (e.g., thermistor networks, pressure bridges) into ADC inputs of PLC I/O modules.

IC Role / Device Role / Timing Role: Linear amplifier in emitter-follower configuration, providing low-output-impedance buffering without inversion.

Use Value: 160–400 h_FE ensures stable bias point across temperature; −5 V V_EBO allows safe operation with ±5 V reference rails.

LED Driver Circuit

Power Supply Enable Switch

Use Scenario: Constant-current switching for indicator LEDs in medical device front panels where EMI and thermal density are constrained.

IC Role / Device Role / Timing Role: Saturated switch controlling LED anode connection to regulated 3.3 V/5 V rail; base driven via current-limiting resistor.

Use Value: −700 mV V_CE(sat) limits power loss to <350 µW per LED at 500 mA, minimizing localized heating near optical components.

Use Scenario: Enabling/disabling auxiliary 3.3 V LDO outputs in embedded computing platforms based on system power-good signals.

IC Role / Device Role / Timing Role: High-side enable switch placing the transistor between input rail and LDO input, controlled by active-low logic signal.

Use Value: −500 mA I_C rating supports >200 mA LDO loads with 2.5× safety margin; SOT23 footprint saves board space vs. SO-8 alternatives.

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
BC807-25	Same h_FE (160–400) and V_CEO (−45 V), but not AEC-Q101 qualified; R_th(j-a) 358 K/W (standard FR4) vs. BC807K-25VL's 157 K/W (4-layer optimized).	Acceptable for commercial-grade consumer or industrial control, but unsuitable for automotive production due to missing qualification.	Select BC807-25 only when AEC-Q101 is not required and thermal budget permits higher junction rise.
MMBT3906LT1G	Lower h_FE (100–300), same V_CEO (−40 V), −200 mA I_C, and −400 mW P_tot; no AEC-Q101 rating.	Limited to low-current (<200 mA) switching; insufficient for 500 mA loads or automotive environments.	Use only in cost-sensitive, non-automotive designs with ≤200 mA load and relaxed thermal constraints.

Compared with BC807-25 and MMBT3906LT1G, BC807K-25VL uniquely combines AEC-Q101 qualification, −500 mA current capability, and 800 mW power dissipation on optimized PCBs-making it the only choice for automotive-grade, high-reliability, medium-power PNP switching where gain consistency and thermal headroom are critical.

FAQ

What is the maximum allowable junction temperature for BC807K-25VL?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in Table 6 of the datasheet. Operation beyond this limit risks permanent degradation of h_FE and increased leakage currents. Thermal design must ensure T_j remains ≤150 °C under worst-case ambient and power dissipation conditions, using the appropriate R_th(j-a) value for the actual PCB construction.

Is BC807K-25VL suitable for linear amplification applications?

Yes-its specified h_FE (160–400), f_T (80 MHz), and low V_CE(sat) support stable Class-A and emitter-follower configurations. However, linearity depends on bias point selection; Figure 7 and Figure 19 show h_FE variation with I_C, and Figure 21–22 provide V_BE vs. I_C curves essential for accurate quiescent point setting.

How does the marking code 'HB%' identify BC807K-25VL on the device?

The top-side marking is 'HB%', where 'HB' denotes the BC807K-25 variant and '%' is a placeholder for the manufacturing site code (e.g., 'HBA' for one facility). This matches Table 5 in the datasheet and is laser-etched on the SOT23 package for traceability; no additional date or lot codes are included in the primary marking.

Can BC807K-25VL replace BC807K-16 or BC807K-40 in existing designs?

Direct replacement is possible only if the circuit tolerates the h_FE shift: BC807K-25 (160–400) sits between BC807K-16 (100–250) and BC807K-40 (250–600). Base resistor values may require adjustment to maintain desired I_C/I_B ratio; verify V_CE(sat) and thermal margin remain within spec under full load at elevated temperature.
