Nexperia USA Inc. PMP4201Y/DG/B3X

Overview

PMP4201Y/DG/B3X from NXP Semiconductors is a matched dual NPN transistor in SOT363 (SC-88) package, designed for precision analog functions requiring tight parameter matching. It delivers h_FE matching ratio ≥0.98, V_BE mismatch ≤2 mV, and individual transistor V_CEO = 45 V, I_C = 100 mA, h_FE = 200–450 (V_CE = 5 V, I_C = 2 mA), enabling high-accuracy current mirroring and differential amplification in compact PCB layouts.

For engineers reviewing the PMP4201Y datasheet, PMP4201Y pinout, PMP4201Y application, or PMP4201Y equivalent, this device is selected where matched gain and base-emitter voltage are critical-especially in bias generation, active load circuits, and low-noise front-end stages where thermal tracking and unit-to-unit consistency directly impact DC operating point stability and common-mode rejection.

Technical Context

The PMP4201Y integrates two fully isolated NPN transistors on a single die within a 6-pin SOT363 package, supporting independent emitter and collector connections per device. Its internal isolation eliminates crosstalk and enables true differential operation without shared substrate paths.

Designed for DC-critical analog topologies, it specifies h_FE1/h_FE2 matching at 0.98 (typical) and V_BE1−V_BE2 ≤ 2 mV under identical bias (V_CE = 5 V, I_C = 2 mA), with thermal resistance R_th(j-a) = 416 K/W per device-enabling stable matching across temperature gradients in surface-mount implementations.

FAQ

What is the maximum allowable junction temperature for PMP4201Y?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in Table 6 of the NXP datasheet. Operation above this limit risks permanent degradation of h_FE matching and V_BE characteristics. Derating is required above ambient temperatures of 85 °C, given the specified R_th(j-a) = 416 K/W per device under standard FR4 PCB conditions.

Can PMP4201Y be used in a common-base configuration?

Yes-each transistor has fully independent base, emitter, and collector terminals, enabling common-base, common-emitter, or common-collector configurations. The SOT363 pinout (Pins 1/2 bases, 5/4 emitters, 6/3 collectors) supports direct routing for common-base setups without signal path interference between devices.

Is the h_FE matching guaranteed across the full operating temperature range?

No-the h_FE1/h_FE2 ≥ 0.98 specification is tested at T_amb = 25 °C per Table 2. While monolithic integration improves thermal tracking, h_FE drift with temperature is not matched; actual ratio may degrade to ~0.95 at −40 °C or +125 °C based on typical h_FE vs. temperature curves in Figure 2 of the datasheet.

Does PMP4201Y support wave soldering?

No-NXP explicitly states in Section 11 that reflow soldering is the only recommended method. Wave soldering is not characterized for this device and may cause thermal stress-induced parameter shift or delamination due to the SOT363 package construction and internal die attachment methodology.
