Nexperia USA Inc. BC807-25LWF

Overview

BC807-25LWF from Nexperia is a PNP general-purpose 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 160–400 at V_CE = −1 V and I_C = −100 mA; used for low-voltage switching and linear amplification in automotive body control modules.

For engineers reviewing the BC807-25LWF datasheet, BC807-25LWF pinout, BC807-25LWF application, or BC807-25LWF equivalent, this page delivers verified electrical parameters, thermal limits, AEC-Q101 qualification status, and real-world use context for automotive-grade discrete selection.

Technical Context

This PNP BJT operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −7 V, supporting robust operation in reverse-biased configurations. Its pulsed h_FE range (160–400) is specified under short-pulse conditions (t_p ≤ 300 μs, duty δ ≤ 0.02), ensuring stable gain behavior in switching waveforms.

Thermal resistance from junction to ambient is 625 K/W in free air (SOT323), requiring careful PCB copper layout for power dissipation up to 200 mW. Saturation performance is characterized at I_C = −500 mA / I_B = −50 mA, delivering V_CE(sat) ≤ −700 mV and V_BE(sat) ≤ −1.2 V - critical for low-loss driver stages.

FAQ

What is the maximum allowable junction temperature for BC807-25LWF?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Limiting Values table. Operation above this threshold risks permanent device degradation. Derating is required above 25 °C ambient - for example, at 85 °C ambient, maximum usable power drops to ~120 mW based on R_th(j-a) = 625 K/W.

Is BC807-25LWF suitable for linear amplification applications?

Yes - its DC current gain (h_FE) is specified from −100 mA to −500 mA at V_CE = −1 V, and Figure 6 shows stable gain vs. collector current across temperature. For low-distortion analog use, bias must maintain V_CE ≥ −1 V and avoid saturation; typical small-signal β remains within 160–400 range.

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

SOT323 has higher thermal resistance: 625 K/W versus 500 K/W for SOT23. This means BC807-25LWF (SOT323) reaches junction temperature faster under identical power dissipation. At 200 mW, ΔT_j-a = 125 °C - so ambient must stay ≤ 25 °C for safe 150 °C T_j. PCB copper area and airflow significantly influence real-world performance.

Does BC807-25LWF support pulse operation beyond its DC ratings?

Yes - peak collector current (I_CM) is rated at −1 A for single pulses ≤ 1 ms, and h_FE is tested under pulsed conditions (t_p ≤ 300 μs, δ ≤ 0.02). Pulse operation allows brief overloads in motor startup or surge suppression, provided average power stays within 200 mW and junction temperature remains ≤ 150 °C.
