Product details
Overview
BC807-40-7-F from Diodes Incorporated is a 45V PNP small-signal transistor in SOT23 package, rated for −50V VCBO, −45V VCEO, and −0.5A continuous collector current, with DC current gain (hFE) of 250–600 at IC = −100mA and VCE = −1.0V, used in low-power switching and audio-frequency amplifier stages.
For engineers reviewing the BC807-40-7-F datasheet, BC807-40-7-F pinout, BC807-40-7-F application, or BC807-40-7-F equivalent, key selection criteria include guaranteed hFE binning (−40 variant), SOT23 thermal resistance (RθJA = 403°C/W on minimum pad layout), ESD robustness (4kV HBM), RoHS/Green compliance, and automotive-grade alternative (BC807-40Q).
Technical Context
This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with verified gain-bandwidth product (fT) of 100MHz at VCE = −5.0V and IC = −10mA, supporting AF amplification up to ~10MHz and fast-switching applications with VCE(sat) ≤ −0.7V at IC = −500mA/IB = −50mA.
Its epitaxial planar die construction ensures stable hFE across temperature (−55°C to +150°C), low leakage (ICES ≤ −5.0µA at VCE = −25V, TJ = +150°C), and compatibility with automated insertion and reflow soldering per J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| hFE (min–max) | 250–600 - Guaranteed DC current gain range at IC = −100mA/VCE = −1.0V, enabling predictable bias design. |
| VCE(sat) | ≤ −0.7V - Low saturation voltage at high drive (IC/IB = 10), minimizing power loss in switching mode. |
| fT | 100MHz - Gain-bandwidth product confirming usable frequency response up to mid-MHz range for AF amplifiers. |
| RθJA | 403°C/W - Thermal resistance on minimal FR4 PCB, defining maximum power dissipation (310mW) at +25°C ambient. |
| ESD HBM | 4,000V - Human Body Model rating ensuring robustness during handling and board assembly. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3-pin configuration, 0.008g mass, UL 94V-0 flammability rating, and matte tin-plated leads compliant with MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal in PNP operation | Connected to higher potential node; defines reference for base control and collector current direction. |
| 2 (Base) | Control input for minority-carrier injection | Receives negative bias current to turn on device; requires current-limiting resistor in linear/switching use. |
| 3 (Collector) | Current source terminal in PNP operation | Supplies load current when saturated; tied to lower-potential rail (e.g., ground) in typical switch topology. |
Key Features
| Feature | Design Value |
|---|---|
| hFE binning (−40 variant) | Guaranteed 250–600 gain range enables consistent bias point setting without post-manufacture sorting. |
| SOT23 footprint | Standardized 3-pin surface-mount outline supports high-density PCB layouts and automated assembly. |
| Lead-free & Green compliance | Halogen- and antimony-free formulation (<900ppm Br/Cl, <1000ppm Sb) meets RoHS 3 and automotive environmental requirements. |
| High-temperature operation | Rated for −55°C to +150°C junction temperature, supporting industrial and under-hood automotive environments. |
Applications
| LED Driver Circuit | Audio Pre-amplifier Stage |
|---|---|
Use Scenario: Driving discrete LEDs in indicator or backlight circuits with PWM dimming. IC Role / Device Role / Timing Role: PNP switch controlling current path from supply rail to LED anode. Use Value: Low VCE(sat) (≤ −0.7V) minimizes voltage drop and heat generation at 100–500mA loads. | Use Scenario: First-stage amplification of microphone or sensor signals in portable audio devices. IC Role / Device Role / Timing Role: Common-emitter small-signal amplifier with fixed bias network. Use Value: High hFE (250–600) ensures stable gain and low input current demand from weak signal sources. |
| Power Supply Enable Switch | Level Translation Interface |
Use Scenario: Enabling/disabling auxiliary rails (e.g., 3.3V or 5V) in multi-rail embedded systems. IC Role / Device Role / Timing Role: High-side switch controlled by microcontroller GPIO. Use Value: Verified −0.5A continuous rating and −1.0A peak capability support reliable rail sequencing. | Use Scenario: Translating logic levels between 5V microcontrollers and 3.3V peripherals. IC Role / Device Role / Timing Role: Inverting level shifter using emitter-follower or common-base configuration. Use Value: fT = 100MHz ensures clean edge transitions up to ~10MHz clock/data rates. |
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 |
|---|---|---|---|
| BC807-40-7 (non-F) | Same electrical specs but lacks "fully RoHS 3" and "Green" certification (halogen/antimony content not controlled). | Not suitable for automotive or strict green-compliance programs requiring halogen-free materials. | Select BC807-40-7-F when full RoHS 3 and Green compliance are mandatory. |
| BC807-40Q | Automotive-qualified version with AEC-Q101 stress testing, same SOT23 package and pinout. | Required for under-hood or safety-critical automotive modules; includes extended temperature validation and PPAP support. | Choose BC807-40Q for automotive production; BC807-40-7-F suffices for industrial/commercial designs. |
Compared with BC807-40-7 and BC807-40Q, the BC807-40-7-F delivers identical electrical performance with certified halogen/antimony-free materials-making it optimal for green-compliant industrial designs where automotive qualification is unnecessary.

FAQ
What is the difference between BC807-40-7-F and BC807-40-7?
The BC807-40-7-F is fully RoHS 3 and "Green" compliant (halogen- and antimony-free), while BC807-40-7 meets basic RoHS but lacks controlled halogen/antimony limits. Both share identical electrical specs, SOT23 package, and marking "K5C", but only the -7-F variant satisfies strict environmental mandates like automotive or EU green procurement policies.
Can BC807-40-7-F replace BC807-25-7-F in a circuit?
Yes, but only if the design tolerates higher hFE: BC807-40-7-F has hFE = 250–600 vs. BC807-25-7-F's 160–400. This may cause overdrive in bias networks optimized for lower gain, potentially increasing power dissipation or reducing switching speed. Verify operating point stability under worst-case hFE extremes before substitution.
Is BC807-40-7-F suitable for automotive applications?
No-BC807-40-7-F is not AEC-Q101 qualified. For automotive use, Diodes offers the BC807-40Q variant, which undergoes extended temperature cycling, humidity testing, and failure analysis per AEC standards. The -7-F part is approved for industrial and commercial applications only.
What is the maximum safe operating current for BC807-40-7-F at 85°C ambient?
At TA = 85°C, derating reduces maximum continuous collector current from −0.5A (at 25°C) to approximately −0.33A, based on the 403°C/W RθJA and 310mW PD limit. This assumes minimum recommended PCB copper area; actual current must be validated against measured junction temperature in the target layout.
