Product details
Overview
BC807-25-7-F from Diodes Incorporated is a 45V PNP small-signal transistor in SOT23 package, with DC current gain (hFE) of 160–250 at IC = −100 mA, VCE = −1.0 V, VCE(sat) ≤ −0.7 V at IC = −500 mA/IB = −50 mA, and fT = 100 MHz. It serves as a general-purpose switching and audio-frequency amplifier device in compact consumer and industrial control circuits.
For engineers reviewing the BC807-25-7-F datasheet, BC807-25-7-F pinout, BC807-25-7-F application, or BC807-25-7-F equivalent, key selection criteria include guaranteed hFE binning (−25 variant), SOT23 thermal performance (RθJA = 403°C/W on minimum pad layout), ESD robustness (HBM 4 kV), and automotive-grade alternatives (e.g., BC807-40Q).
Technical Context
This PNP bipolar junction transistor uses epitaxial planar die construction for stable gain and low leakage. Its −45 V VCEO, −50 V VCBO, and −5.0 V VEBO ratings support operation in moderate-voltage bias networks, while its 310 mW power dissipation (on FR4) and 100 MHz fT enable use in both DC-coupled switching and mid-band amplification up to ~10 MHz.
The device is fully lead-free, halogen- and antimony-free ("Green"), and rated to −55°C to +150°C operating temperature. Its SOT23 package features matte tin-plated leads compliant with MIL-STD-202 Method 208, and moisture sensitivity level 1 per J-STD-020 - enabling standard reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −45 V: Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| hFE (IC = −100 mA) | 160–250: Guaranteed DC current gain range for reliable base drive sizing in linear or saturated switch design. |
| VCE(sat) | ≤ −0.7 V at IC/IB = −500/−50 mA: Low saturation voltage ensures minimal conduction loss in high-current switching. |
| fT | 100 MHz: Gain-bandwidth product confirms usable frequency response up to ~10 MHz in amplifier configurations. |
| PD (TA = 25°C) | 310 mW on min-pad FR4: Defines maximum continuous power under standard PCB layout conditions. |
| ESD HBM | 4,000 V: Robustness against human-body electrostatic discharge supports handling in non-EPA environments. |
Pinout & Package
Package: SOT23 - surface-mount plastic package with 3 terminals, 0.008 g mass, UL 94V-0 flammability rating, and JEDEC-standard footprint (2.9 mm × 1.3 mm × 1.0 mm max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal for PNP operation | Connected to higher potential (e.g., VCC) in common-emitter switches; polarity-sensitive for correct biasing. |
| 2 (Base) | Control input for minority-carrier injection | Requires negative current relative to emitter to turn on; resistor value selected using hFE bin and IC target. |
| 3 (Collector) | Current sink terminal | Typically connected to load and ground; voltage swing limited by VCEO and thermal derating above 25°C. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed hFE bin (−25) | 160–250 at −100 mA ensures predictable base drive requirements across production lots. |
| Low VCE(sat) | ≤ −0.7 V at high IC/IB ratio minimizes power loss and self-heating in saturated switching. |
| Automated insertion compatibility | SOT23 tape-and-reel packaging (3,000 pcs/reel, 8 mm tape) supports high-speed pick-and-place assembly. |
| "Green" compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) meets global environmental directives without performance trade-offs. |
Applications
| LED Driver Circuit | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V logic rails using MCU output pins with limited sink capability. IC Role / Device Role / Timing Role: PNP switch configured in common-emitter mode to source current to LED anode while sinking through cathode to ground. Use Value: Guaranteed hFE ≥160 ensures full saturation with ≤200 µA base drive, preserving GPIO current budget and reducing board-level component count. | Use Scenario: Level-shifting and signal inversion between 1.8 V/3.3 V microcontrollers and 5 V peripherals (e.g., legacy sensors or displays). IC Role / Device Role / Timing Role: Single-transistor inverter with pull-up resistor, providing rail-to-rail logic inversion and voltage translation. Use Value: VCEO = −45 V and low VCE(sat) allow clean 5 V output swing with sub-100 ns propagation delay in digital interface paths. |
| Power Supply Enable Control | Audio Pre-amplifier Stage |
Use Scenario: Enabling/disabling 12 V auxiliary rails in embedded systems via low-side MCU output controlling PNP gate/base. IC Role / Device Role / Timing Role: High-side switch driver where BC807-25 enables PMOS or PNP pass transistors in LDO or DC-DC enable paths. Use Value: −500 mA IC rating and 310 mW PD support direct drive of enable inputs drawing up to 100 µA, eliminating need for additional buffer stages. | Use Scenario: Low-noise pre-amplification of microphone or sensor signals in portable audio devices operating from single 3.3 V supply. IC Role / Device Role / Timing Role: Common-emitter amplifier biased at IC ≈ −1 mA, leveraging 100 MHz fT and low CCBO (12 pF) for flat 20 Hz–20 kHz response. Use Value: hFE consistency and low VBE(on) (≤ −1.2 V) simplify bias network design and improve gain stability over temperature. |
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 | No "-F" suffix; same electrical specs but unspecified halogen/antimony status per datasheet notes. | Not certified "Green"; may not meet latest environmental compliance requirements for EU/Asia shipments. | Select only if RoHS 3/halogen-free certification is not required and cost is primary constraint. |
| BC807-40-7-F | Higher hFE bin (250–600); otherwise identical absolute max ratings, package, and thermal specs. | Better suited for ultra-low-base-drive applications (e.g., battery-powered sensors), but may exhibit greater gain variation at low IC. | Choose when base current must be minimized below 50 µA, accepting wider hFE spread and slightly higher cost. |
Compared with BC807-25-7 and BC807-40-7-F, the BC807-25-7-F delivers optimal balance of guaranteed gain, ESD robustness, and environmental compliance - making it preferred for volume production in industrial controls and consumer electronics where consistent drive and regulatory adherence are critical.

FAQ
What is the marking code for BC807-25-7-F on the SOT23 package?
The top-side marking for BC807-25-7-F is "K5B", as specified in the Diodes ordering information table. This 3-character code identifies the device variant, with "K5" indicating the BC807 family and "B" denoting the −25 hFE bin. The date code follows adjacent to this marking per Diodes' standard format.
Does BC807-25-7-F support reflow soldering per JEDEC J-STD-020?
Yes - BC807-25-7-F has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to unlimited floor life and standard Pb-free reflow profiles (peak temperature ≤ 260°C) without baking. Its matte tin-plated leads are qualified per MIL-STD-202 Method 208 for solderability.
How does BC807-25-7-F differ from the automotive-grade BC807-40Q?
BC807-40Q is AEC-Q101 qualified, with extended temperature testing (−40°C to +150°C), enhanced process controls, and PPAP documentation support. Electrically, it shares the same −45 V VCEO and 310 mW PD, but is binned to hFE = 250–400 and carries separate qualification data - making it suitable for automotive body electronics, not general industrial use.
Can BC807-25-7-F replace BC857B in existing designs?
Yes - BC807-25-7-F and BC857B share identical SOT23 pinout, VCEO = −45 V, and hFE range (200–450 for BC857B vs. 160–250 for BC807-25). However, BC807-25-7-F has lower fT (100 MHz vs. 300 MHz) and higher VCE(sat) (−0.7 V vs. −0.55 V), so verify switching speed and conduction loss in high-frequency or low-voltage applications.
