Product details

Overview

BC807-40LWF from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) 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 delivers low V_CE(sat) of −700 mV at I_C = −500 mA / I_B = −50 mA and supports automotive-grade operation per AEC-Q101. It is used in discrete load switching and signal amplification stages in power management modules.

For engineers reviewing the BC807-40LWF datasheet, BC807-40LWF pinout, BC807-40LWF application, or BC807-40LWF equivalent, this page provides verified electrical parameters, thermal resistance (625 K/W), SOT323 pin mapping, AEC-Q101 qualification status, and direct alternatives with documented h_FE and package differences.

Technical Context

This PNP BJT operates in linear or saturation mode with guaranteed h_FE ≥250 at I_C = −100 mA and exhibits stable gain across −40 °C to +150 °C ambient range. Its V_BE is −1.2 V at I_C = −500 mA, enabling predictable base drive requirements in high-current switching circuits.

The device features an absolute maximum V_CBO of −50 V and V_EBO of −7 V, supporting robust reverse-bias tolerance in bidirectional interface protection and level-shifting applications. Thermal resistance R_th(j-a) is 625 K/W in free air, defining its derating behavior on minimal copper PCBs.

Key Specifications

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
BC807-40LT	SOT23 package (TO-236AB); R_th(j-a) = 500 K/W; P_tot = 250 mW	Higher power handling but larger footprint; less suitable for ultra-dense layouts	Select when board space permits and thermal margin >50 mW is required beyond SOT323 limits
MMBT4403	h_FE = 100–300; V_CEO = −40 V; not AEC-Q101 qualified	Limited gain range and no automotive qualification; lower cost for non-automotive consumer use	Choose only for cost-sensitive, non-automotive applications where h_FE ≥250 is not required

Compared with BC807-40LWF, BC807-40LT offers 25% higher power dissipation but occupies 40% more PCB area, while MMBT4403 trades AEC-Q101 compliance and gain headroom for lower unit cost in commercial-grade systems.

FAQ

What is the maximum continuous collector current for BC807-40LWF?

The maximum continuous collector current (I_C) is −500 mA at T_amb ≤ 25 °C on FR4 PCB with single-sided copper. At elevated ambient temperatures, derating applies per the 200 mW total power dissipation limit and 625 K/W thermal resistance.

Is BC807-40LWF suitable for automotive applications?

Yes - BC807-40LWF is AEC-Q101 qualified for discrete semiconductors, validated for temperature cycling, humidity testing, and mechanical shock per automotive reliability standards, making it suitable for under-hood and body-control modules.

How does the SOT323 package affect thermal performance compared to SOT23?

The SOT323 package has higher junction-to-ambient thermal resistance (625 K/W) than SOT23 (500 K/W), resulting in ~25% greater temperature rise per watt. This requires stricter layout rules - such as increased copper pour - to maintain safe junction temperatures at full rated current.

What is the typical V_BE at I_C = −500 mA?

The typical base-emitter voltage (V_BE) is −1.2 V at V_CE = −1 V and I_C = −500 mA, measured under pulsed conditions (t_p ≤ 300 μs, duty cycle ≤ 0.02). This value defines minimum base drive voltage needed for full saturation in high-current switching.
