NXP Semiconductors MPSA06,116

Overview

MPSA06,116 from Nexperia (formerly Philips Semiconductors) is an NPN general-purpose bipolar junction transistor in a TO-92 (SOT54) package, rated for 80 V V_CEO, 500 mA I_C, and 625 mW P_tot, commonly used in low-power switching and linear amplification circuits in consumer electronics and industrial control interfaces.

For engineers reviewing the MPSA06,116 datasheet, MPSA06,116 pinout, MPSA06,116 application, or MPSA06,116 equivalent, key selection criteria include its DC current gain (h_FE ≥ 100 at 10–100 mA), low saturation voltage (V_CEsat ≤ 250 mV), transition frequency (f_T ≥ 100 MHz), and compatibility with through-hole PCB assembly.

Technical Context

The MPSA06,116 operates as a standard NPN BJT with fixed emitter-base and collector-base junctions optimized for DC and low-frequency AC operation. Its h_FE remains stable across 10–100 mA collector current, and V_CEsat is specified under forced β = 10 (I_C/I_B = 10), confirming suitability for saturated switching.

Thermal performance is defined for mounting on FR4 PCB (R_th(j-a) = 200 K/W); maximum junction temperature is 150 °C, and storage ambient range spans −65 °C to +150 °C - supporting industrial-grade reliability without heatsinking at moderate loads.

FAQ

What is the maximum collector-emitter voltage rating for MPSA06,116?

The MPSA06,116 has a maximum collector-emitter voltage (V_CEO) rating of 80 V under open-base conditions. This rating applies at T_amb ≤ 25 °C and must be derated linearly above that temperature per the datasheet thermal curves. Exceeding 80 V risks avalanche breakdown and permanent device failure. The MPSA06,116 is therefore appropriate for 24 V and 48 V system rails but not for 100 V+ applications.

Is MPSA06,116 suitable for linear amplification applications?

Yes, the MPSA06,116 is explicitly characterized for linear amplification, with h_FE guaranteed ≥ 100 at both 10 mA and 100 mA collector current and V_CE = 1 V. Its f_T ≥ 100 MHz and low noise profile support audio-frequency pre-amplifier stages. However, thermal stability must be verified in continuous bias configurations due to its 625 mW power limit and 200 K/W junction-to-ambient resistance.

What is the pin configuration of MPSA06,116 when viewed from the flat side with leads pointing downward?

When viewing the MPSA06,116 TO-92 package from the flat side with leads pointing downward, the pin order from left to right is: Pin 1 (Collector), Pin 2 (Base), Pin 3 (Emitter). This matches the official Nexperia pinning diagram and is consistent across all SOT54-marked units. Misalignment during PCB layout can cause functional failure, so orientation verification before assembly is essential for the MPSA06,116.

Does MPSA06,116 have a PNP complement, and is it available from Aetrix Electronics?

Yes, the PNP complement of the MPSA06,116 is the MPSA56, which shares identical packaging (TO-92/SOT54), voltage ratings (80 V), and current capability (500 mA), enabling complementary push-pull or differential pair designs. The MPSA56 is also stocked by Aetrix Electronics and cross-referenced in the same product family documentation as the MPSA06,116 for matched pair sourcing.

What is the thermal resistance junction-to-ambient for MPSA06,116, and how does it affect PCB layout?

The MPSA06,116 has a junction-to-ambient thermal resistance (R_th(j-a)) of 200 K/W when mounted on a standard FR4 PCB with minimal copper area. This means a 125 mW power dissipation raises junction temperature by ~25 °C above ambient. To maintain T_j < 150 °C at 70 °C ambient, keep average power below ~400 mW - achievable via increased copper pour or thermal vias. This thermal behavior is documented in the official MPSA06,116 datasheet.
