Product details

Overview

BC807-25,235 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 operates across −65 °C to +150 °C ambient temperature and delivers ≤700 mV V_CE(sat) at I_C = −500 mA / I_B = −50 mA, commonly used in low-voltage logic-level switching and signal amplification stages.

For engineers reviewing the BC807-25,235 datasheet, BC807-25,235 pinout, BC807-25,235 application, or BC807-25,235 equivalent, key selection criteria include verified h_FE binning (160–400), thermal resistance (362 K/W on 1 cm² collector pad), SOT23 pin compatibility, and −5 V V_EBO for emitter-base reverse tolerance in level-shifting circuits.

Technical Context

This PNP BJT functions as a current-controlled switch or linear amplifier with fixed polarity and no integrated biasing. Its h_FE range is binned during production to ensure consistent gain behavior across the 160–400 window under pulsed conditions (t_p ≤ 300 μs, δ ≤ 0.02).

Thermal performance is defined for two PCB mounting configurations: standard footprint (R_th(j-a) = 500 K/W) and enhanced 1 cm² collector pad (R_th(j-a) = 362 K/W). Absolute maximum ratings include −50 V V_CBO, −45 V V_CEO, and −5 V V_EBO, all tested at T_amb = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in PNP switch applications.
I_C	−500 mA - Continuous DC collector current rating; sets load-driving capability in relay drivers or LED sinks.
h_FE	160–400 - Verified DC current gain range at V_CE = −1 V, I_C = −100 mA; enables predictable base drive sizing.
V_CE(sat)	≤ −700 mV - Collector-emitter saturation voltage at I_C = −500 mA / I_B = −50 mA; determines conduction loss in saturated switching.
V_EBO	−5 V - Emitter-base breakdown voltage; limits reverse-bias tolerance in level-shift or clamping configurations.
P_tot	345 mW - Max power dissipation with 1 cm² copper pad; defines thermal derating envelope for sustained operation.
f_T	80 MHz - Transition frequency at V_CE = −5 V, I_C = −10 mA; indicates usable bandwidth for small-signal amplification.

Pinout & Package

BC807-25,235 uses the industry-standard SOT23 (TO-236AB) plastic surface-mount package, measuring 2.9 mm × 1.3 mm × 1.0 mm with gull-wing leads and 0.95 mm lead pitch. Thermal design requires either standard footprint (500 K/W R_th(j-a)) or extended collector pad (362 K/W).

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires external resistor network to set operating point and prevent thermal runaway.
2	Emitter (E)	Common terminal for PNP configuration; connected to higher potential rail in high-side switch topologies.
3	Collector (C)	Output current path; sinks load current to ground or lower-potential node when biased on.

Key Features

Feature	Design Value
Three h_FE bins	BC807-25 provides 160–400 h_FE, enabling precise base drive optimization without overdesigning bias networks.
High V_CEO rating	−45 V supports operation in 24 V industrial control rails and automotive 12 V systems with margin for transients.
Low V_CE(sat)	≤ −700 mV at full 500 mA load minimizes power loss and self-heating in continuous switching applications.
SOT23 footprint	Standardized 3-pin SMT package ensures drop-in compatibility with existing layout libraries and reflow processes.
Extended temperature range	−65 °C to +150 °C operation supports deployment in harsh environments including motor control enclosures and outdoor electronics.

Applications

Industrial Relay Driver

Microcontroller GPIO Expander

Use Scenario: Driving 24 V DC coil relays from 3.3 V or 5 V microcontroller outputs via base-resistor interface.

IC Role / Device Role / Timing Role: PNP switch sinking relay coil current to ground while isolating MCU I/O from inductive kickback.

Use Value: −45 V V_CEO withstands relay flyback spikes; 160–400 h_FE allows reliable turn-on with ≤10 mA base drive.

Use Scenario: Level-shifting and current boosting for low-drive GPIO pins controlling LEDs, buzzers, or small solenoids.

IC Role / Device Role / Timing Role: Signal amplifier and current buffer between weak MCU output and higher-current load.

Use Value: ≤700 mV V_CE(sat) ensures minimal voltage drop; SOT23 size fits dense PCB layouts near microcontroller packages.

Automotive Body Control Module

Consumer Appliance Power Sequencing

Use Scenario: Controlling 12 V lamp loads and HVAC actuators in non-safety-critical vehicle subsystems.

IC Role / Device Role / Timing Role: High-side load switch (emitter to battery rail) enabling controlled power delivery.

Use Value: −65 °C to +150 °C rating meets under-hood thermal requirements; −5 V V_EBO tolerates reverse-battery test conditions.

Use Scenario: Enabling/disabling auxiliary power rails (e.g., display backlight, sensor bias) during appliance boot-up or standby.

IC Role / Device Role / Timing Role: Low-power enable switch activated by system controller to gate downstream power paths.

Use Value: 345 mW P_tot with 1 cm² pad supports continuous 200 mA operation; marking code '5B%' enables traceability in mass production.

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
BC807-25,115	Same electrical specs and SOT23 package; differs only in tape-and-reel packaging (115 vs. 235) and reel size (3,000 vs. 10,000 units).	No functional difference; selected based on procurement volume and assembly line feeder compatibility.	Choose 115 for prototyping or low-volume SMT lines; 235 for high-throughput production with larger reels.
BC807-25W,115	Same h_FE bin but in SOT323 (SC-70) package - 2.2 mm × 1.35 mm, 0.65 mm pitch - with 400 mW P_tot and 625 K/W R_th(j-a).	Smaller footprint suits ultra-dense boards but sacrifices thermal performance and peak current handling.	Select W-variant only when board space is critical and load current remains ≤300 mA with active thermal management.

Compared with BC807-25,235, the 115 variant offers identical silicon performance in different packaging for flexible logistics, while the BC807-25W trades thermal robustness and current capacity for miniaturization - making the 235 optimal for thermally constrained yet medium-power applications.

FAQ

What is the marking code for BC807-25,235?

The marking code printed on the device body is '5B%', where '%' represents a placeholder for the manufacturing site identifier. This code is standardized across all BC807-25 variants and enables rapid visual identification on assembled PCBs and during incoming inspection.

Does BC807-25,235 support automotive applications?

No - BC807-25,235 is explicitly designated as non-automotive qualified per Nexperia's revision history (v.8, July 2022). It lacks AEC-Q101 qualification, automotive-grade screening, and guaranteed PPAP documentation. For automotive use, select the BC807-25Q series instead.

How does thermal performance differ between standard and enhanced PCB mounting?

With standard SOT23 footprint (single-sided FR4, tin-plated), R_th(j-a) is 500 K/W; with 1 cm² collector pad, it improves to 362 K/W. This 27% reduction allows 345 mW continuous dissipation versus 250 mW - directly extending safe operating time at 500 mA load current.

Can BC807-25,235 replace BC807-16 in an existing design?

Yes, electrically - both share identical package, pinout, voltage/current ratings, and absolute maxima. However, BC807-25's higher h_FE (160–400 vs. 100–250) may reduce required base drive current by up to 40%, potentially lowering base resistor power dissipation and improving noise immunity in marginal bias conditions.
