Product details

Overview

BC807-40LR 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 250–600 at V_CE = −1 V and I_C = −100 mA. It operates across −55 °C to +150 °C ambient, supports automotive-grade reliability per AEC-Q101, and is used in low-voltage load switching and signal amplification circuits.

For engineers reviewing the BC807-40LR datasheet, BC807-40LR pinout, BC807-40LR application, or BC807-40LR equivalent, this page delivers verified electrical parameters, thermal limits, package dimensions, real-world use cases, and validated alternative transistors - all aligned with Nexperia's official product data sheet Rev. 1 (2018).

Technical Context

This PNP BJT features a silicon planar epitaxial structure optimized for stable DC current gain across temperature (250–600 at I_C = −100 mA), low V_CE(sat) (≤ −700 mV at I_C = −500 mA / I_B = −50 mA), and robust breakdown ratings: −45 V V_CEO, −50 V V_CBO, and −7 V V_EBO. Its pulsed operation capability supports peak collector current up to −1 A (t_p ≤ 1 ms).

Thermal resistance from junction-to-ambient is 500 K/W when mounted on standard FR4 PCB (single-sided copper), enabling reliable operation up to T_j = 150 °C. The device is qualified to AEC-Q101, confirming suitability for automotive body electronics and industrial control modules requiring long-term bias stability.

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 high-side switch designs.
I_C	−500 mA continuous: Rated collector current under steady-state conditions; supports medium-power load driving.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA: High and tightly binned DC current gain enables precise biasing in amplifier and linear regulator feedback paths.
V_CE(sat)	≤ −700 mV at I_C = −500 mA, I_B = −50 mA: Low saturation voltage minimizes conduction loss in switching applications.
P_tot	250 mW (SOT23): Maximum power dissipation on standard FR4 PCB; sets thermal derating boundary for continuous operation.
T_j max	+150 °C: Maximum junction temperature; allows deployment in engine bay or industrial enclosures without active cooling.
AEC-Q101	Qualified: Validated for automotive applications including lighting control, sensor interface, and power management subsystems.

Pinout & Package

SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, compact footprint (2.9 mm × 1.3 mm × 1.0 mm), designed for reflow and wave soldering per IPC-7095 guidelines.

Pin	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires −50 mA drive for full saturation at −500 mA collector load.
2	Emitter (E)	Common terminal for PNP topology; connected to higher potential rail (e.g., +12 V) in high-side switch configurations.
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	BC807-40L offers 250–600 h_FE, enabling predictable gain matching in production amplifiers and current mirrors.
AEC-Q101 qualification	Validated for automotive temperature cycling, humidity bias, and mechanical shock - suitable for under-hood ECUs.
Low V_BE	≤ −1.2 V at I_C = −500 mA ensures minimal base drive voltage overhead in 3.3 V or 5 V logic-controlled switches.
High I_CM	−1 A peak (t_p ≤ 1 ms) supports inrush current handling in relay drivers and solenoid interfaces.
SC-70-compatible variant	BC807-40LW shares identical electrical specs in smaller SOT323 package - enables layout flexibility without performance trade-off.

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
BC807-40,115 (Nexperia)	Same electrical specs and SOT23 package; differs only in tape-and-reel packaging (10,000 pcs/reel vs. 3,000 pcs/reel for BC807-40LR).	No functional difference; identical use in circuit design and layout.	Select BC807-40,115 for high-volume automated assembly where reel size impacts feeder setup time.
MMBT4403 (ON Semiconductor)	−40 V V_CEO, −600 mA I_C, h_FE = 100–300; slightly lower voltage rating and narrower gain range than BC807-40LR.	Acceptable for non-automotive 5 V/12 V logic-level switching but lacks AEC-Q101 validation.	Choose MMBT4403 only for cost-driven consumer applications where automotive qualification is unnecessary.

Compared with BC807-40LR, BC807-40,115 offers identical performance with optimized packaging for SMT lines, while MMBT4403 trades AEC-Q101 compliance and higher V_CEO for broader availability and lower unit cost in non-automotive contexts.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA (single pulse, t_p ≤ 1 ms), but for continuous DC operation, the recommended limit is −50 mA - derived from the I_C/I_B = 10 condition used in saturation testing and confirmed by thermal derating curves in the datasheet.

Can BC807-40LR replace BC807-25L in an existing design?

Yes, BC807-40LR can directly replace BC807-25L in most cases: both share identical package, pinout, voltage/current ratings, and thermal characteristics. The key difference is h_FE (250–600 vs. 160–400), which may increase base current margin but requires verification of base drive capability in high-gain-critical circuits.

Is the SOT23 footprint compatible with automated optical inspection (AOI)?

Yes - the SOT23 outline (2.9 mm × 1.3 mm) and pad layout defined in Figure 18 (Reflow soldering footprint) meet IPC-7351B Class B standards, supporting reliable AOI detection of solder joint integrity, tombstoning, and misalignment in high-speed SMT lines.

Does BC807-40LR support pulsed operation beyond its DC ratings?

Yes - it supports −1 A peak collector current (I_CM) for pulses ≤ 1 ms with duty cycle ≤ 2%, as specified in Table 6. This enables short-duration surge handling in relay coil drivers and ESD protection clamping circuits without thermal runaway.
