Nexperia USA Inc. BC807-16HZ

Overview

BC807-16HZ 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 100–250 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 and signal conditioning circuits.

For engineers reviewing the BC807-16HZ datasheet, BC807-16HZ pinout, BC807-16HZ application, or BC807-16HZ equivalent, key selection criteria include its −45 V breakdown rating, thermal robustness to 175 °C, SOT23 footprint compatibility, and verified h_FE range under pulsed and DC conditions per IEC 60134 limiting values.

Technical Context

This transistor implements a silicon planar epitaxial structure optimized for stable DC current gain across wide temperature ranges (−55 °C to +175 °C). Its base-emitter saturation voltage remains ≤ −1.2 V at I_C = −500 mA / I_B = −50 mA, supporting efficient low-side switching in compact DC-DC feedback paths and load control stages.

The device features low parasitic capacitances-C_c = 7 pF at V_CB = −10 V and C_e = 50 pF at V_EB = −0.5 V-enabling operation up to 80 MHz transition frequency (f_T) under specified bias, making it suitable for moderate-speed digital interface buffering and analog pre-amplification where bandwidth exceeds audio range.

FAQ

What is the maximum allowable base current for BC807-16HZ?

The absolute maximum peak base current is −200 mA for single pulses ≤1 ms at 25 °C ambient. For continuous operation, base current must be limited to ensure I_C ≤ −500 mA and junction temperature stays within −55 °C to +175 °C. Designers should apply I_B = I_C/h_FE(min) using the 100 minimum gain value to guarantee saturation under worst-case conditions.

Does BC807-16HZ support wave soldering?

Yes-Nexperia provides dedicated wave soldering footprint data (Fig. 45) specifying 1.4 mm pad width, 2.2 mm pad length, and 2.6 mm center-to-center spacing for reliable through-hole compatible assembly. The device meets JEDEC J-STD-020 moisture sensitivity level 1 and is rated for standard wave profiles without preconditioning.

How does thermal resistance vary with PCB construction?

R_th(j-a) ranges from 470 K/W (single-layer FR4, standard footprint) to 280 K/W (4-layer FR4 with 1 cm² collector pad). This 190 K/W difference directly impacts steady-state temperature rise: at 300 mW dissipation, junction-to-ambient delta-T shifts from 141 °C to 84 °C-necessitating layout-aware derating per Figure 1.

Is BC807-16HZ qualified for automotive applications?

No-Revision 2 explicitly states this part has been changed to non-automotive qualification. Automotive-grade equivalents (e.g., BC807-16Q) are available separately with AEC-Q101 certification, enhanced testing, and different revision history. BC807-16HZ is intended for industrial, medical, and consumer applications meeting standard JEDEC reliability requirements.
