Nexperia USA Inc. BC807-25HVL

Overview

BC807-25HVL from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 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. It operates reliably up to 175 °C junction temperature and serves as a low-voltage switching or linear amplification device in power management, signal conditioning, and discrete logic interface circuits.

For engineers reviewing the BC807-25HVL datasheet, BC807-25HVL pinout, BC807-25HVL application, or BC807-25HVL equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternatives for industrial control, automotive body electronics, and consumer power stage design.

Technical Context

The BC807-25HVL implements a silicon planar epitaxial PNP BJT structure optimized for stable DC current gain across wide temperature ranges (−55 °C to +175 °C) and robust safe operating area (SOA) under pulsed conditions (I_CM = −1 A, t_p ≤ 1 ms). Its base-emitter saturation voltage remains ≤ −1.2 V at I_C = −500 mA / I_B = −50 mA, enabling efficient drive in low-side switch configurations.

Thermal performance is defined by R_th(j-a) values ranging from 280 K/W (4-layer PCB, 1 cm² collector pad) to 470 K/W (single-sided FR4), with transient impedance curves confirming suitability for repetitive pulse loads. The device exhibits f_T = 80 MHz at V_CE = −5 V / I_C = −10 mA, supporting moderate-frequency amplification tasks.

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, base current must be limited to ensure I_C ≤ −500 mA and junction temperature stays within +175 °C. Using h_FE(min) = 160, maximum recommended I_B is −3.125 mA at I_C = −500 mA to maintain saturation without overdriving.

Does BC807-25HVL meet automotive qualification standards?

BC807-25HVL itself is qualified for industrial temperature range (−55 °C to +175 °C) and is not AEC-Q101 certified. However, Nexperia offers the pin-compatible BC807-25Q variant, which carries full AEC-Q101 qualification and is intended for automotive body electronics applications where stress testing and failure rate validation are mandatory.

How does PCB layout affect its power dissipation capability?

Power dissipation varies significantly with PCB construction: 320 mW on single-sided FR4 with standard footprint, rising to 540 mW on 4-layer FR4 with 1 cm² collector pad. Thermal resistance R_th(j-a) drops from 470 K/W to 280 K/W under optimized layout, directly impacting allowable continuous current in thermally constrained designs.

Can BC807-25HVL replace BC807-16H in an existing design?

Yes - BC807-25HVL is a direct upgrade with higher minimum h_FE (160 vs 100), identical V_CEO, I_C, and package. No layout or biasing changes are needed. Higher gain may reduce required base drive current, lowering MCU GPIO loading or enabling smaller base resistors, but verify saturation margin at worst-case h_FE(max) = 400.
