Nexperia USA Inc. PMP4201G,115

Overview

PMP4201G from Nexperia is a matched NPN/NPN double transistor in SOT353 (SC-88A) package, designed for precision analog functions requiring tight h_FE matching (0.98 min) and V_BE matching (≤2 mV). It supports 45 V V_CEO, 100 mA I_C, and AEC-Q101 qualification, enabling use in automotive current mirrors and differential amplifiers.

For engineers reviewing the PMP4201G datasheet, PMP4201G pinout, PMP4201G application, or PMP4201G equivalent, key selection criteria include per-transistor DC current gain (200–450), matched pair performance (h_FE1/h_FE2 ≥ 0.98), common-emitter configuration, and thermal resistance (416 K/W for full device).

Technical Context

This dual NPN transistor integrates two fully isolated transistors in a single TSSOP5 footprint, sharing only the emitter terminal (Pin 2). Its design enables precise current mirroring and differential signal processing without cross-coupling.

The device operates with matched h_FE and V_BE under identical bias conditions (V_CE = 5 V, I_C = 2 mA, T_amb = 25 °C), and supports reflow-only soldering on FR4 PCBs with defined thermal resistance (R_th(j-a) = 416 K/W for the device).

FAQ

Is PMP4201G suitable for wave soldering?

No. The datasheet explicitly states that reflow soldering is the only recommended method. Wave soldering is not qualified due to thermal profile constraints and potential damage to the SOT353 package. Reflow profiles must follow JEDEC J-STD-020 guidelines for MSL1 devices.

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature is 150 °C. For continuous operation, derating is required above 25 °C ambient: total device power must be reduced linearly beyond 25 °C using R_th(j-a) = 416 K/W, reaching zero dissipation at 100.7 °C ambient.

How is h_FE1/h_FE2 matching measured and guaranteed?

Matching is measured per transistor at V_CE = 5 V, I_C = 2 mA, T_amb = 25 °C; the ratio uses the smaller h_FE as numerator. The 0.98 minimum is production-tested and guaranteed across the full operating temperature range per AEC-Q101 qualification.

Can Pin 2 (E1/E2) be left unconnected?

No. Pin 2 is the common emitter terminal for both transistors and must be externally connected to establish the reference node. Leaving it floating invalidates bias conditions and prevents proper operation of either transistor.
