Product details

Overview

BC807-25QBZ from Nexperia is a PNP general-purpose bipolar junction transistor in a leadless DFN1110D-3 (SOT8015) 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 serves as a compact, surface-mount switching or amplification device in space-constrained consumer and industrial PCBs.

For engineers reviewing the BC807-25QBZ datasheet, BC807-25QBZ pinout, BC807-25QBZ application, or BC807-25QBZ equivalent, this part is selected for low-profile, AOI-compatible PNP switching where thermal performance on FR4 PCBs and precise h_FE binning are critical design factors.

Technical Context

The BC807-25QBZ operates as a silicon PNP BJT with base-controlled current amplification, optimized for linear amplification and saturated switching. Its DFN1110D-3 package features side-wettable flanks for automated optical inspection and solder-joint reliability verification.

It delivers V_CE(sat) ≤ −700 mV at I_C = −500 mA / I_B = −50 mA and exhibits f_T = 80 MHz at V_CE = −5 V, I_C = −10 mA, enabling use in medium-speed digital logic interfaces and analog signal conditioning up to several megahertz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum safe collector-emitter voltage under open-base conditions; defines upper rail limit in PNP switch configurations.
I_C	−500 mA - Continuous DC collector current rating; supports load switching up to ~0.5 A at ambient temperature.
h_FE	160–400 - Guaranteed DC current gain range at V_CE = −1 V, I_C = −100 mA; enables predictable base drive sizing for saturation.
V_CE(sat)	≤ −700 mV - Collector-emitter saturation voltage at I_C = −500 mA / I_B = −50 mA; ensures low conduction loss in switching applications.
f_T	80 MHz - Transition frequency at V_CE = −5 V, I_C = −10 mA; supports small-signal amplification and fast digital edge handling.
P_tot	350 mW (FR4, 35 μm Cu) - Total power dissipation limit; determines thermal derating in standard PCB layouts.
R_th(j-a)	358 K/W - Junction-to-ambient thermal resistance on standard FR4; informs temperature rise estimation under steady-state bias.

Pinout & Package

DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin plastic package measuring 1.1 × 1.0 × 0.48 mm with side-wettable flanks for reliable reflow solder joint inspection.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires current-limited drive to achieve target I_C; polarity-sensitive for PNP operation.
2	Emitter (E)	Current source terminal; connected to higher potential rail in PNP switch configuration; anchors internal reference.
3	Collector (C)	Current sink terminal; connects to load; voltage swing limited by V_CEO and thermal constraints.

Key Features

Feature	Design Value
Side-wettable flanks	Enables automated optical inspection (AOI) of solder joints without X-ray; improves manufacturing yield in high-volume SMT lines.
Ultra-small footprint	1.1 mm × 1.0 mm body area - reduces PCB real estate by >50% vs. conventional SOT23, critical for wearables and miniaturized modules.
Low profile (0.48 mm height)	Minimizes Z-axis clearance requirements; compatible with stacked-board assemblies and low-clearance enclosures.
Three h_FE bins	BC807-25QBZ provides mid-range gain (160–400), enabling consistent base resistor selection across production lots without recalibration.
Thermal enhancement	Exposed die pad (terminal 2/E) acts as primary thermal path; achieves 350–460 mW power dissipation depending on copper thickness.

Applications

LED Driver Circuit

Microcontroller GPIO Expander

Use Scenario: Driving 20–50 mA indicator LEDs from 3.3 V or 5 V rails in portable instrumentation.

IC Role / Device Role / Timing Role: PNP switch sinking current from LED anode to ground; configured in common-emitter mode with base driven by MCU output.

Use Value: Low V_CE(sat) minimizes forward voltage drop, preserving LED brightness; tight h_FE bin ensures uniform LED intensity across multiple channels.

Use Scenario: Level-shifting and current boosting for legacy 5 V peripherals interfaced with 3.3 V microcontrollers.

IC Role / Device Role / Timing Role: Active-low buffer stage translating logic-high (3.3 V) to 5 V pull-up; used in I²C bus extenders or reset signal conditioners.

Use Value: Fast f_T and low input capacitance (5 pF) preserve signal edge integrity; side-wettable flanks ensure solder joint reliability in mixed-voltage board assemblies.

Power Rail Sequencing

Low-Power Sensor Interface

Use Scenario: Enabling/disabling auxiliary 3.3 V or 2.5 V supply rails during system startup or sleep mode transitions.

IC Role / Device Role / Timing Role: High-side PNP switch controlling PMOS gate or LDO enable pin; base driven via RC-delayed MCU output.

Use Value: −45 V V_CEO provides margin against transient overshoot; 0.5 mm package height avoids interference with adjacent tall components like connectors.

Use Scenario: Amplifying weak analog signals (e.g., thermistor, photodiode) in battery-powered environmental sensors.

IC Role / Device Role / Timing Role: Common-emitter amplifier stage with emitter degeneration; biased in linear region for DC-coupled gain.

Use Value: Stable h_FE over −55 °C to +150 °C ensures calibration retention; low leakage (I_CBO ≤ −100 nA) preserves accuracy in µA-level bias networks.

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
BC807-25W	SOT323 package (2.1 × 1.25 × 0.95 mm); no side-wettable flanks; h_FE same range but higher R_th(j-a) (~400 K/W).	Less suitable for AOI-dependent high-volume production; better suited for prototyping or low-density boards where height is less constrained.	Select when legacy footprint compatibility or hand-soldering is prioritized over automated inspection and miniaturization.
MMBT3906LT1G	SOT23 package; V_CEO = −40 V; h_FE = 100–300; V_CE(sat) = −400 mV @ I_C = −10 mA (not rated at 500 mA).	Lower current capability limits use to <100 mA loads; superior V_CE(sat) only at light loads; not validated for 500 mA continuous operation.	Choose only for low-current signal switching (<100 mA); avoid for power switching due to missing I_C = −500 mA rating and thermal derating data.

Compared with BC807-25W and MMBT3906LT1G, BC807-25QBZ uniquely combines AOI-ready packaging, −500 mA current rating, and guaranteed mid-bin h_FE-making it optimal for space-constrained, high-reliability production of consumer and industrial control modules.

FAQ

What is the maximum continuous collector current for BC807-25QBZ?

The BC807-25QBZ is rated for −500 mA continuous collector current (I_C) at T_amb = 25 °C. This rating assumes proper PCB thermal management-specifically, mounting on FR4 with ≥35 μm copper-and derates linearly above 25 °C per the published power derating curve (350 mW at 25 °C, zero at ~125 °C).

Does BC807-25QBZ support automatic optical inspection (AOI)?

Yes-BC807-25QBZ uses the DFN1110D-3 (SOT8015) package with side-wettable flanks, explicitly designed for reliable AOI of solder joints. The exposed flank geometry allows camera-based systems to verify fillet formation and wetting without requiring X-ray inspection, improving first-pass yield in high-volume SMT lines.

How does the h_FE bin of BC807-25QBZ compare to BC807-16QB and BC807-40QB?

BC807-25QBZ has a guaranteed h_FE range of 160–400 at V_CE = −1 V and I_C = −100 mA, positioning it between BC807-16QB (100–250) and BC807-40QB (250–600). This mid-bin selection balances base drive efficiency and gain stability, reducing sensitivity to process variation while avoiding excessive base current in high-gain designs.

Can BC807-25QBZ be used in automotive applications?

No-BC807-25QBZ is not automotive-qualified. Per Nexperia's revision history, the BC807QB_SER series was explicitly changed to non-automotive qualification in Rev. 2 (July 2023). For automotive use, engineers must select Nexperia's dedicated −Q qualified variants (e.g., BC807-25QB-Q), which undergo extended temperature testing and AEC-Q101 stress validation.
