Nexperia USA Inc. BC807K-16R

Overview

BC807K-16R from Nexperia is a PNP general-purpose bipolar junction transistor (BJT) in SOT23 (TO-236AB) package, rated for −45 V collector-emitter voltage and −500 mA continuous collector current, with DC current gain (h_FE) of 100–250 at V_CE = −1 V and I_C = −100 mA. It serves as a low-voltage switching or linear amplification device in automotive body control modules, industrial sensor interfaces, and power supply enable circuits.

For engineers reviewing the BC807K-16R datasheet, BC807K-16R pinout, BC807K-16R application, or BC807K-16R equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, SOT23 footprint details, and validated alternative transistors for automotive-grade discrete design.

Technical Context

This PNP BJT operates in active, saturation, and cutoff regions with defined breakdown limits: V_CEO = −45 V, V_CBO = −50 V, and V_EBO = −5 V. Its pulsed operation supports peak collector current up to −1 A (t_p ≤ 1 ms), and base-emitter saturation voltage is −1.2 V max at I_C = −500 mA / I_B = −50 mA.

Thermal performance varies by PCB construction: R_th(j-a) ranges from 157 K/W (4-layer FR4, 1 cm² collector pad) to 358 K/W (single-sided FR4, standard footprint). Transition frequency f_T is 80 MHz at V_CE = −5 V, I_C = −10 mA, enabling moderate-speed switching in <10 MHz digital logic interfaces.

FAQ

What is the maximum allowable junction temperature for BC807K-16R?

The absolute maximum junction temperature (T_j) is 150 °C per IEC 60134 limiting values. Operation above this temperature risks permanent degradation of h_FE and increased leakage. Derating begins at 25 °C ambient, with R_th(j-a) ranging from 157 K/W (optimized 4-layer PCB) to 358 K/W (basic single-sided board).

Is BC807K-16R pin-compatible with BC807-16?

Yes - both use identical SOT23 (TO-236AB) package with pin 1 (base), pin 2 (emitter), pin 3 (collector) assignment. However, BC807K-16R features tighter h_FE binning (100–250 vs. 100–250 for BC807-16), improved thermal resistance, and AEC-Q101 qualification not present in the legacy BC807 series.

Can BC807K-16R be used in linear amplification mode?

Yes - its specified h_FE, V_BE, and f_T characteristics support common-emitter and emitter-follower configurations. At I_C = −10 mA and V_CE = −1 V, h_FE is stable between 160–220, and f_T remains ≥60 MHz, enabling audio-frequency and low-speed signal buffering up to ~100 kHz.

What is the meaning of the 'K' suffix in BC807K-16R?

The 'K' denotes Nexperia's enhanced version: improved thermal performance (lower R_th(j-a)), tighter h_FE distribution, AEC-Q101 qualification, and optimized die attach for higher reliability. The 'R' suffix indicates tape-and-reel packaging (standard for SMT assembly), not a functional variant.
