Nexperia USA Inc. PMP3906AYS-QZ

Overview

PMP3906AYS-Q from Nexperia is a matched dual PNP bipolar transistor in SOT363-3 (TSSOP6) package, designed for precision analog functions requiring tight parameter matching. It delivers ±2 mV base-emitter voltage matching and 0.98–1.00 DC current gain ratio per device at V_CE = −5 V, I_C = −2 mA, and supports automotive-grade operation up to 150 °C junction temperature.

For engineers reviewing the PMP3906AYS-Q datasheet, PMP3906AYS-Q pinout, PMP3906AYS-Q application, or PMP3906AYS-Q equivalent, key selection criteria include matched h_FE tracking across temperature, AEC-Q101 qualification, low V_BE mismatch for current mirror accuracy, and thermal performance on FR4 PCBs with 357 K/W per-device R_th(j-a).

Technical Context

This matched double PNP transistor integrates two electrically symmetric transistors optimized for differential pair and current mirror topologies. Its design enforces tight matching of h_FE (ratio ≥0.98) and V_BE (Δ ≤2 mV) under identical bias conditions, achieved via monolithic die layout and process-controlled emitter geometry.

The device operates with V_CEO = −40 V and I_C = −200 mA per transistor, supporting stable biasing in high-reliability analog signal paths. Thermal resistance is specified at 357 K/W (per device, FR4 PCB), enabling predictable power derating up to 125 °C ambient without exceeding 150 °C T_j.

FAQ

Is PMP3906AYS-Q pin-compatible with standard SOT363 dual transistors?

Yes-PMP3906AYS-Q uses the SOT363-3 (TSSOP6) package with identical mechanical dimensions and 0.65 mm lead pitch as industry-standard SOT363. Pin 1 (B1) aligns with the index mark, and the pinout matches the graphic symbol in Figure 10 of the datasheet, ensuring drop-in replacement in existing footprints.

What is the maximum allowable power dissipation at 105 °C ambient temperature?

At 105 °C ambient, the per-device power dissipation must be limited to 225 mW. This is derived from the 357 K/W R_th(j-a) and 150 °C T_j max: (150 − 105) °C ÷ 357 K/W = 0.126 W. Derating follows the linear curve in Figure 1, confirming 225 mW at 105 °C.

Does the h_FE matching specification apply across the full operating temperature range?

No-the h_FE1/h_FE2 ≥ 0.98 specification is tested at Tamb = 25 °C per Table 4. However, Figure 3 shows h_FE curves for −55 °C, 25 °C, and 150 °C, indicating consistent tracking behavior across temperature; actual matching at extremes is not guaranteed by datasheet limits.

Can PMP3906AYS-Q be used in AC-coupled amplifier stages?

Yes-its f_T of 250 MHz and low capacitances (C_c = 4.5 pF, C_e = 10 pF) support stable operation up to ~50 MHz in common-emitter configurations. NF = 4 dB at 1 kHz confirms suitability for low-noise audio and sensor front-end amplification when biased appropriately.
