Nexperia USA Inc. PMP4201Y,115

Overview

PMP4201Y from Nexperia is an AEC-Q101-qualified NPN/NPN matched double transistor in SOT363-3 (TSSOP6) package, rated for 45 V V_CEO, 100 mA I_C, and featuring h_FE matching ratio ≥0.98 and V_BE matching ≤2 mV at 2 mA/5 V - optimized for precision current mirroring and differential amplification in automotive signal conditioning circuits.

For engineers reviewing the PMP4201Y datasheet, PMP4201Y pinout, PMP4201Y application, or PMP4201Y equivalent, this device delivers verified transistor pair matching, automotive-grade reliability, and application-optimized pinout for compact high-fidelity analog front-ends requiring minimal thermal drift and inter-device parameter correlation.

Technical Context

This dual NPN transistor integrates two electrically matched silicon epitaxial planar transistors on a single die, with tightly controlled h_FE ratio (0.98–1.0) and base-emitter voltage difference (≤2 mV) under identical bias conditions (V_CE = 5 V, I_C = 2 mA, T_amb = 25 °C). Its monolithic construction ensures consistent thermal coupling and tracking across temperature.

The device operates within absolute maximum ratings of 45 V V_CEO, 100 mA continuous I_C, and 150 °C junction temperature, with total device power dissipation up to 300 mW on FR4 PCB. It exhibits f_T ≥100 MHz at I_C = 10 mA and low noise figure (≤3.3 dB at 1 kHz), supporting stable small-signal amplification and mirror accuracy in feedback-sensitive topologies.

FAQ

What is the maximum allowable junction temperature for PMP4201Y?

The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of h_FE matching and V_BE tracking. Derating is required above 25 °C ambient - at 100 °C ambient, maximum continuous power must be reduced to ≤120 mW per transistor to maintain T_j ≤ 150 °C.

Is PMP4201Y pin-compatible with older PMP4201V or PMP4201G variants?

Yes - all share identical SOT363-3 (TSSOP6) pinout and mechanical footprint. The revision change from PMP4201V_G_Y_4 to PMP4201Y reflects updated package definition (SOT363 → SOT363-3) and enhanced process control, but electrical pin functions (B1/B2/C1/C2/E1/E2) and physical dimensions remain unchanged.

How does the h_FE matching ratio of 0.98 translate to actual circuit performance?

A ratio of 0.98 means the smaller h_FE value divided by the larger equals 0.98 - i.e., ≤2% gain mismatch. In a current mirror biased at 2 mA, this yields output current error <±20 µA, directly limiting offset in precision reference generators and reducing calibration steps in production test.

Can PMP4201Y be used in linear regulator pass elements?

No - its 100 mA I_C rating and 300 mW total power dissipation limit safe linear operation to <300 mW at ≤150 °C junction temperature. It lacks the SOA robustness and thermal mass required for sustained pass-element duty; intended instead for signal-level matching, not power regulation.
