Nexperia USA Inc. BC806-16HVL

Overview

BC806-16HVL from Nexperia is a PNP general-purpose bipolar junction transistor in SOT23 package, rated for −80 V V_CEO, −500 mA I_C, 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 robust switching or amplification device in 48 V automotive board nets and industrial control interfaces.

For engineers reviewing the BC806-16HVL datasheet, BC806-16HVL pinout, BC806-16HVL application, or BC806-16HVL equivalent, key selection criteria include its −80 V breakdown voltage, thermal stability at 175 °C, SOT23 footprint compatibility, and verified performance under pulsed 1 A I_CM conditions with low V_CEsat (≤ −400 mV at I_C = −500 mA, I_B = −50 mA).

Technical Context

This PNP BJT features a silicon planar epitaxial structure optimized for high-voltage switching and linear amplification. Its absolute maximum ratings include −80 V V_CEO and −80 V V_CBO, with guaranteed operation across −55 °C to +175 °C ambient range. The device exhibits low base-emitter saturation voltage (V_BEsat ≤ −1.2 V) and transition frequency f_T = 80 MHz at V_CE = −5 V, I_C = −50 mA.

Thermal design is supported by documented R_th(j-a) values: 500 K/W on standard FR4 PCB and 363 K/W with 1 cm² collector pad. Its emitter capacitance (C_e = 47 pF) and collector capacitance (C_c = 5 pF) are specified at 1 MHz, enabling predictable high-frequency behavior in switching waveforms.

FAQ

Is BC806-16HVL qualified for automotive applications?

No. Per Nexperia's revision history (Rev. 2, 30 September 2025), BC806H_SER explicitly states "Product(s) changed to non-automotive qualification." Automotive use requires Nexperia's −Q qualified variants (e.g., BC806-16Q), which undergo AEC-Q101 testing and have different traceability and screening protocols.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −200 mA (single pulse, tp ≤ 1 ms). For continuous DC operation, base current must be limited to ensure junction temperature remains ≤175 °C. At I_C = −500 mA and h_FE = 100, I_B ≈ −5 mA is typical; sustained I_B > −10 mA requires thermal evaluation using R_th(j-a) = 500 K/W.

Can BC806-16HVL replace BC806-16 in existing designs?

Yes. BC806-16HVL is a direct replacement for BC806-16, sharing identical electrical specifications, SOT23 package dimensions, pinout, and marking (QN%). The "HVL" suffix denotes enhanced process control and tighter parameter distribution per Nexperia's HVL (High Voltage Low leakage) series designation.

How does thermal derating affect power dissipation at 100 °C ambient?

At T_amb = 100 °C, P_tot must be reduced from 300 mW (25 °C) using the derating curve in Figure 1. With R_th(j-a) = 500 K/W, allowable P_tot ≈ 150 mW (ΔT = 75 K × 0.002 W/K = 150 mW), confirming safe operation at I_C = −300 mA with V_CEsat ≈ −300 mV (P ≈ 90 mW).
