Nexperia USA Inc. BC807-25LZ

Overview

BC807-25LZ 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 160–400 at V_CE = −1 V and I_C = −100 mA. It delivers 250 mW power dissipation on FR4 PCB and supports automotive-grade operation per AEC-Q101. Used in low-voltage switching and signal amplification circuits such as LED drivers and logic-level translators.

For engineers reviewing the BC807-25LZ datasheet, BC807-25LZ pinout, BC807-25LZ application, or BC807-25LZ equivalent, this page provides verified electrical parameters, thermal behavior, SOT23 pin mapping, real-world use cases, and qualified alternatives - all aligned with Nexperia's Rev. 1 (Jan 2018) product data sheet.

Technical Context

This PNP BJT operates in active and saturation regions with guaranteed h_FE range of 160–400 under pulsed conditions (t_p ≤ 300 μs, duty δ ≤ 0.02), enabling stable current amplification in bias-sensitive analog stages. Its −7 V V_EBO and −50 V V_CBO support robust base-emitter and collector-base reverse blocking in rail-to-rail interface designs.

Thermal resistance R_th(j-a) is 500 K/W when mounted on standard FR4 PCB, limiting continuous I_C to 500 mA only with adequate copper area and ambient derating. Saturation voltage V_CE(sat) remains ≤ −700 mV at I_C = −500 mA / I_B = −50 mA, confirming suitability for low-loss switching below 1 V supply rails.

FAQ

What is the maximum allowable base current for BC807-25LZ in continuous operation?

The absolute maximum peak base current is −200 mA per datasheet Table 6, but continuous operation must respect thermal limits. With I_C = −500 mA and h_FE ≥ 160, required I_B is ≤ −3.125 mA. Derating to ≤ −2 mA ensures long-term reliability and avoids localized heating at the base-emitter junction.

Does BC807-25LZ support operation at −40 °C ambient temperature?

Yes - the specified operating ambient temperature range is −55 °C to +150 °C (Table 5). Electrical characteristics including h_FE and V_CE(sat) are characterized down to −40 °C in Figures 6–9, showing only moderate gain reduction and slightly increased saturation voltage, fully within functional margins for most switching applications.

Can BC807-25LZ be used in linear amplifier configurations?

Yes - its h_FE stability across I_C (Figure 6), low noise profile, and 80 MHz f_T support Class-A and Class-AB small-signal amplification up to ~100 kHz. However, thermal limitations (250 mW P_tot) restrict usable quiescent current; bias networks must ensure junction temperature stays ≤125 °C under worst-case ambient and power dissipation.

Is the SOT23 package of BC807-25LZ compatible with automated optical inspection (AOI)?

Yes - the SOT23 outline (Figure 16) features clearly defined lead geometry, consistent solder mask clearance (0.15 mm side gap), and standardized 0.95 mm height, meeting IPC-A-610 Class 2/3 AOI detectability requirements. Marking code "HM%" (Table 5) is laser-etched with ≥0.15 mm character height, ensuring reliable machine-readability post-reflow.
