Product details
Overview
BC807-25W-7 from Diodes Incorporated is a 45V PNP small-signal transistor in SOT323 package, rated for -500mA continuous collector current, with DC current gain (hFE) of 160–400 at -100mA/-1.0V, and VCE(sat) ≤ -700mV at -500mA/-50mA. It serves as a general-purpose switching and audio-frequency amplifier device in compact board-level power control circuits.
For engineers reviewing the BC807-25W-7 datasheet, BC807-25W-7 pinout, BC807-25W-7 application, or BC807-25W-7 equivalent, key selection criteria include its PNP polarity, SOT323 thermal resistance (RθJA = 625°C/W), guaranteed hFE binning, ESD robustness (HBM 4kV), and automotive-grade manufacturing capability under IATF 16949.
Technical Context
This PNP bipolar junction transistor uses epitaxial planar die construction to deliver stable DC current gain across temperature (-65°C to +150°C) and consistent saturation performance under pulsed conditions (pulse width ≤ 300µs, duty cycle ≤ 2%). Its complementary NPN counterpart is BC817-25W-7.
The device operates with VCEO = -45V, VCB0 = -50V, and VEB0 = -6V, supporting reliable cutoff and conduction in low-voltage logic-level interface and load-switching topologies where base drive is sourced from microcontroller GPIO or level-shifted signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -45 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| IC (cont.) | -500 mA - Continuous collector current rating defining usable load-driving capacity at ambient temperature |
| hFE | 160–400 - DC current gain range at -100mA/-1.0V, enabling predictable base resistor sizing for switch saturation |
| VCE(sat) | ≤ -700 mV - Low saturation voltage at -500mA/-50mA, minimizing power loss in high-current switching |
| fT | 100 MHz - Gain-bandwidth product confirming suitability for audio-frequency amplification and fast digital switching |
| RθJA | 625 °C/W - Junction-to-ambient thermal resistance on minimum FR4 pad layout, guiding PCB copper area requirements |
| ESD HBM | 4,000 V - Human Body Model robustness level, reducing risk of handling damage during assembly |
Pinout & Package
Package: SOT323 - ultra-compact surface-mount plastic package (2.15 × 2.10 × 0.95 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current exit terminal in PNP operation; connected to higher potential rail in high-side switch configurations |
| 2 (Base) | B | Control input requiring negative bias relative to emitter to turn on; typical RB calculated using hFE min |
| 3 (Collector) | C | Current entry terminal; tied to load and ground return path in common-emitter switch applications |
Key Features
| Feature | Design Value |
|---|---|
| Epitaxial planar die construction | Ensures tight parameter distribution and stable hFE over temperature and lifetime |

| Lead-free, halogen- and antimony-free "Green" compound | Meets RoHS 3 (2015/863/EU) and automotive change-control requirements without compromising solderability |
| Automotive qualification readiness | Manufactured in IATF 16949-certified facilities with PPAP capability for AEC-Q101-compliant derivative variants |
Applications
| LED Driver Circuit | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving 20–100mA indicator LEDs from 3.3V/5V logic rails with current limiting via base resistor. IC Role / Device Role / Timing Role: PNP switch controlling LED anode connection to VCC, sinking current through cathode to ground. Use Value: Low VCE(sat) ensures ≥95% efficiency at 50mA, while hFE binning allows precise base resistor selection without margin overdesign. |
Use Scenario: Level-shifting and inverting logic signals between 1.8V MCU outputs and 5V peripheral inputs. IC Role / Device Role / Timing Role: Active-low buffer providing signal inversion and voltage translation with minimal propagation delay. Use Value: fT = 100MHz supports clean edge transitions up to ~10MHz, and ESD HBM = 4kV protects against field-induced gate oxide stress. |
| Low-Voltage Power Switch | Audio Pre-amplifier Stage |
Use Scenario: Enabling/disabling 3.3V or 5V subsystems (e.g., sensors, radios) using MCU-controlled high-side power gating. IC Role / Device Role / Timing Role: High-side PNP switch with emitter tied to supply, collector to load, base driven via pull-up/pull-down network. Use Value: VCEO = -45V provides 10× headroom over 5V systems, and RθJA = 625°C/W enables thermal safety margin on standard 1oz FR4. |
Use Scenario: Single-stage common-emitter pre-amplifier for electret microphone output (10–20mV AC) into ADC input. IC Role / Device Role / Timing Role: Linear-mode PNP amplifier biased at -100mA, delivering voltage gain via RC load and emitter degeneration. Use Value: hFE stability across -50°C to +150°C ensures consistent gain in industrial enclosures, and low noise figure supports SNR > 60dB. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC807-25-7 (SOT23) | SOT23 package (larger footprint, RθJA = 350°C/W), same electrical specs, different marking and tape width | Less space-constrained boards where thermal dissipation priority exceeds miniaturization | Select when PCB layout allows larger pad area and higher power derating is required |
| MMBT2907ALT1G (SOT23) | Higher VCEO (-60V), lower hFE (100–300), same SOT23 footprint, ON Semiconductor branding | High-reliability industrial controls needing extended voltage margin and legacy supply chain support | Choose when system voltage may transiently exceed 45V or long-term vendor diversification is mandated |
Compared with BC807-25W-7, the SOT23 alternatives offer better thermal performance but sacrifice board-area efficiency; MMBT2907ALT1G trades hFE consistency for wider voltage tolerance, making it preferable in overvoltage-prone environments but less optimal for precision gain-critical bias networks.

FAQ
What is the maximum operating temperature for BC807-25W-7?
The BC807-25W-7 has an operating junction temperature range of -65°C to +150°C. Its thermal resistance (RθJA = 625°C/W) means that at 200mW power dissipation on a standard FR4 board, junction temperature rise is approximately 125°C above ambient-so maximum ambient must be limited to +25°C for full-rated operation. Derating is required above that point.
Is BC807-25W-7 suitable for automotive applications?
BC807-25W-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While the base part is not AEC-Q101 qualified, Diodes offers automotive-grade variants (e.g., BC807-25WQ-7) with full qualification, traceability, and change control-contact Diodes or Aetrix for qualified part numbers and test reports.
How does the SOT323 package affect PCB layout?
The SOT323 footprint (2.15 × 2.10 mm) requires precise stencil aperture design and reflow profile tuning due to its small lead pitch (0.65 mm). Recommended pad dimensions are C = 0.65 mm, G = 1.30 mm, X = 0.47 mm, Y = 0.60 mm, and Y1 = 2.50 mm per Diodes' suggested layout-critical to avoid tombstoning and ensure solder joint integrity.
What is the meaning of the "K5B" marking on BC807-25W-7?
"K5B" is the top-side product marking: "K5" identifies the BC807-25W series, and "B" denotes the hFE grade (160–400). The date code follows (e.g., "N9" = 2026, September). This marking enables visual verification of gain bin and production traceability without requiring electrical test at incoming inspection.
