Product details

Overview

BC807-40W/MIF from Nexperia is a PNP bipolar junction transistor (BJT) in SOT323 (SC-70) package, rated for −45 V V_CEO, −500 mA continuous collector current, and DC current gain (h_FE) of 250–600 at V_CE = −1 V and I_C = −100 mA. It serves as a general-purpose switching and amplification device in low-power analog and digital interface circuits.

For engineers reviewing the BC807-40W/MIF datasheet, BC807-40W/MIF pinout, BC807-40W/MIF application, or BC807-40W/MIF equivalent, key selection criteria include guaranteed h_FE range, SOT323 thermal derating behavior, V_CEsat ≤ −700 mV at I_C = −500 mA/I_B = −50 mA, and compatibility with reflow-soldered high-density PCB layouts.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with defined absolute maximum ratings: −45 V V_CEO, −500 mA I_C, and 290 mW P_tot on FR4 PCB with 1 cm² collector pad. Its pulsed h_FE (250–600) and low V_CEsat support reliable switching in logic-level interfacing and load control.

Thermal resistance R_th(j-a) is 431 K/W under optimized mounting (1 cm² collector pad), enabling stable operation up to 150 °C junction temperature. Base-emitter voltage is −1.2 V at I_C = −500 mA, with −2 mV/K temperature coefficient confirmed in characteristics data.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V - Maximum safe collector-emitter voltage with base open; defines off-state blocking capability in switching applications.
I_C	−500 mA - Continuous DC collector current rating; sets upper limit for steady-state load drive without thermal runaway.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA - Guaranteed DC current gain range ensures predictable base drive sizing for saturation.
V_CEsat	≤ −700 mV at I_C = −500 mA, I_B = −50 mA - Low saturation voltage minimizes power loss and heating in switched-mode operation.
P_tot	290 mW on FR4 PCB with 1 cm² collector pad - Thermal power limit determines maximum dissipation before derating applies.
f_T	80 MHz at V_CE = −5 V, I_C = −10 mA - Transition frequency supports small-signal amplification up to mid-VHF band.

Pinout & Package

BC807-40W/MIF is housed in a SOT323 (SC-70) surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density PCB assembly and reflow soldering per JEDEC standard footprint.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; requires −12 mA typical base drive to saturate at I_C = −500 mA (IC/IB = 42).
2	Emitter (E)	Current source terminal; connected to higher potential rail in PNP switching configurations.
3	Collector (C)	Current sink terminal; routed to load or ground reference; thermally coupled to PCB pad for heat dissipation.

Key Features

Feature	Design Value
Three h_FE variants in same package	Enables precise gain matching across designs without layout change-BC807-40W offers highest gain (250–600) for low-base-drive applications.
Optimized for SMT reflow	SOT323 outline meets JEDEC MO-203-DA; solder footprint (2.65 mm × 2.35 mm) supports automated placement and IPC Class 3 reliability.
Low V_CEsat at high current	≤ −700 mV at I_C = −500 mA ensures <150 mW conduction loss, critical for battery-powered and thermally constrained systems.
High f_T with low C_c	80 MHz f_T and 5 pF collector capacitance enable stable small-signal amplification without external compensation.

Applications

LED Driver Circuit

Microcontroller GPIO Interface

Use Scenario: Driving 20 mA indicator LEDs from 3.3 V microcontroller outputs via common-emitter switch.

IC Role / Device Role / Timing Role: PNP current sink switch controlled by inverted GPIO signal; provides level translation and current gain.

Use Value: Guaranteed h_FE ≥ 250 ensures ≤ 80 µA base current required, minimizing GPIO loading and preserving drive strength for other peripherals.

Use Scenario: Inverting logic signals between 5 V legacy peripherals and 3.3 V MCU inputs.

IC Role / Device Role / Timing Role: Active-low level shifter with fast turn-off due to low C_c (5 pF) and high f_T (80 MHz).

Use Value: V_CEsat ≤ −700 mV guarantees output low-level < 0.7 V, meeting 3.3 V logic '0' threshold with margin.

Power Supply Enable Switch

Audio Signal Amplifier Stage

Use Scenario: Enabling/disabling a 12 V auxiliary rail using MCU-controlled high-side switch.

IC Role / Device Role / Timing Role: High-side PNP pass transistor with base resistor network; operates in saturation for minimal dropout.

Use Value: −45 V V_CEO rating provides 3× safety margin over 12 V rail, preventing breakdown during load dump transients.

Use Scenario: Low-noise preamplifier stage for electret microphone biasing and signal buffering.

IC Role / Device Role / Timing Role: Common-emitter amplifier with emitter degeneration; configured for 20 dB voltage gain at audio frequencies.

Use Value: 80 MHz f_T and flat h_FE response up to 10 kHz ensure distortion-free amplification across full voiceband (300 Hz–3.4 kHz).

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	Same electrical specs but in larger SOT23 package; R_th(j-a) = 625 K/W vs. 431 K/W for BC807-40W.	Less suitable for space-constrained, high-density layouts where SC-70 footprint is mandatory.	Select BC807-40W/MIF when board area is limited and thermal performance on FR4 with 1 cm² pad is required.
MMBT3906LT1G	Lower h_FE range (100–300); V_CEsat = −400 mV max at I_C = −100 mA (not −500 mA); same SOT23 package.	Not recommended for 500 mA switching loads due to unspecified V_CEsat and power derating at high current.	Choose BC807-40W/MIF for designs requiring guaranteed −500 mA operation with ≤ −700 mV saturation voltage.

Compared with BC807-40 and MMBT3906LT1G, BC807-40W/MIF delivers superior thermal performance in ultra-compact layout, verified h_FE ≥ 250 at full rated current, and tighter V_CEsat specification-making it optimal for miniaturized industrial controls and portable electronics.

FAQ

What is the maximum allowable junction temperature for BC807-40W/MIF?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in Table 6 of the Nexperia datasheet. Operation above this temperature risks permanent parametric shift or failure. Derating begins at ambient temperatures exceeding 25 °C, with total power dissipation reduced linearly per the curve in Figure 1.

Does BC807-40W/MIF support wave soldering?

Yes-Nexperia provides a dedicated wave soldering footprint (Figure 18) with 3.65 mm × 2.1 mm land pattern and 2.575 mm preferred transport direction. The SOT323 package is qualified for both reflow and wave processes, though reflow is preferred for consistent thermal profile control and void minimization.

How does the h_FE of BC807-40W/MIF vary with temperature?

h_FE increases with rising junction temperature: Figure 12 shows typical values of ~600 at T_amb = 150 °C versus ~400 at 25 °C for I_C = −100 mA. This positive temperature coefficient must be considered in bias-stable amplifier designs to avoid thermal runaway in un-compensated configurations.

Is BC807-40W/MIF automotive-qualified?

No-per Section 14 of the datasheet, BC807W series devices are explicitly non-automotive qualified. They lack AEC-Q101 stress testing and are not warranted for use in safety-critical or life-support systems. For automotive applications, Nexperia recommends the BC807W-Q series with documented qualification evidence.
