Product details
Overview
BC807-25W-QX from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for −45 V VCEO, −500 mA IC, and DC current gain (hFE) of 160–400 at VCE = −1 V and IC = −100 mA. It serves as a compact, AEC-Q101-qualified switching and amplification device in space-constrained automotive and industrial control circuits.
For engineers reviewing the BC807-25W-QX datasheet, BC807-25W-QX pinout, BC807-25W-QX application, or BC807-25W-QX equivalent, this page delivers verified electrical parameters, thermal derating behavior, automotive qualification status, and real-world use context for reliable component selection and PCB layout planning.
Technical Context
This PNP BJT operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, supporting robust operation in negative-rail bias configurations. Its pulsed hFE range (160–400) and low VCE(sat) of −700 mV at IC = −500 mA / IB = −50 mA enable efficient low-voltage switching in discrete logic-level interfaces.
Thermal resistance Rth(j-a) is 625 K/W on standard FR4 PCB and improves to 431 K/W with enhanced 1 cm² collector pad, directly informing power budgeting in thermally constrained modules. The device's 80 MHz fT and 5 pF Cc support stable performance up to mid-frequency analog and digital signal conditioning tasks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V - Maximum safe collector-emitter voltage under open-base condition; defines rail compatibility in negative-supply switching stages. |
| IC | −500 mA - Continuous DC collector current rating; sets maximum load drive capability in linear or saturated operation. |
| hFE | 160–400 - DC current gain at VCE = −1 V, IC = −100 mA; determines required base drive for predictable saturation in switching designs. |
| VCE(sat) | −700 mV - Collector-emitter saturation voltage at IC = −500 mA / IB = −50 mA; directly impacts conduction loss and thermal rise in high-current switches. |
| fT | 80 MHz - Transition frequency at VCE = −5 V, IC = −10 mA; confirms suitability for audio-frequency amplification and fast digital edge shaping. |
| Cc | 5 pF - Collector capacitance at VCB = −10 V; limits high-frequency bandwidth and affects stability in RF-coupled or fast-switching applications. |
| Ptot | 200 mW - Total power dissipation on standard FR4 PCB; constrains usable IC×VCE product in ambient-temperature-limited layouts. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: ultra-compact 3-lead outline measuring 2.2 mm × 1.35 mm × 0.95 mm (L × W × H), optimized for high-density automotive PCBs and portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Current-controlled input node; requires ≥13 mA peak base drive to saturate at 500 mA collector load per datasheet Fig. 11. |
| 2 | Emitter (E) | Common reference terminal for PNP topology; connected to higher potential rail (e.g., +VCC) in typical switch configurations. |
| 3 | Collector (C) | Output current path; sinks load current to ground or lower-potential node when base is driven low relative to emitter. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standards; validated for under-hood temperature cycling, humidity, and mechanical shock in production vehicles. |
| Three hFE selections | BC807-25W-QX provides mid-range 160–400 gain-enabling precise base resistor sizing without overdesign or marginal turn-on in sensor interface or LED driver stages. |
| Low VCE(sat) | −700 mV at full 500 mA load ensures ≤350 mW conduction loss, reducing thermal stress in sealed enclosures and extending reliability in continuous-duty applications. |
| High fT and low Cc | 80 MHz transition frequency with only 5 pF collector capacitance supports clean square-wave response in PWM dimming and motor gate drive buffering. |
Applications
| Automotive Door Module Switching | Industrial PLC Input Buffer |

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 |
|---|---|---|---|
| BC807-25-7-F (Diodes Inc.) | Same SOT323 package, identical −45 V/−500 mA ratings, but hFE range 160–320 (narrower upper bound); no AEC-Q101 certification. | Lacks automotive qualification; suitable for commercial-grade industrial controls but not safety-critical vehicle subsystems. | Select when cost sensitivity outweighs automotive compliance requirements and gain tolerance of ±20% is acceptable. |
| MMBT3906LT1G (ON Semiconductor) | Same package and polarity, but lower −40 V VCEO, −200 mA IC, and hFE 100–300; higher VCE(sat) (−400 mV @ −100 mA). | Insufficient for 500 mA loads or 45 V transient protection; limited to low-power signal inversion or biasing. | Choose only for space-constrained non-automotive designs where <200 mA switching suffices and 40 V margin is adequate. |
Compared with BC807-25W-QX, BC807-25-7-F offers identical electrical specs but lacks AEC-Q101 validation, while MMBT3906LT1G trades current capacity and voltage headroom for broader availability-making the Nexperia part optimal for automotive-grade 500 mA switching where qualification and thermal margin are mandatory.

FAQ
What is the maximum allowable junction temperature for BC807-25W-QX?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in Table 6 of the Nexperia datasheet. This limit applies under all operating conditions, including pulsed and continuous modes. Exceeding this value risks permanent parametric shift or catastrophic failure, especially during transient overload events.
Does BC807-25W-QX support wave soldering?
Yes-Nexperia provides a dedicated wave soldering footprint (Fig. 18) with 3.65 mm × 2.1 mm land pattern and 2.575 mm preferred transport direction. The device is qualified for lead-free wave processes per J-STD-020, with peak temperature ≤260 °C and dwell time ≤10 seconds, provided solder mask and pad geometry match the recommended layout.
How does the hFE of BC807-25W-QX vary with temperature?
hFE increases with rising junction temperature: Fig. 8 shows typical gain rising from ~250 at −55 °C to ~350 at 25 °C and ~400 at 150 °C (at IC = −100 mA). Designers must account for this positive thermal coefficient when sizing base resistors for stable bias in wide-temperature applications like engine control units.
Is BC807-25W-QX pin-compatible with BC807-16W-Q or BC807-40W-Q?
Yes-all BC807W-Q variants share identical SOT323 package, pin 1 (base), pin 2 (emitter), pin 3 (collector) assignment, and mechanical footprint. Only hFE ranges differ (160–400 vs. 100–250 vs. 250–600), allowing direct substitution where gain tolerance permits without layout changes.
