Nexperia USA Inc. PUMZ2,115

Overview

PUMZ2 from NXP Semiconductors is an NPN/PNP general-purpose double transistor in SOT363 (SC-88) package, integrating complementary bipolar junction transistors on a single die for compact dual-polarity switching and amplification. It supports 50 V V_CEO, 150 mA I_C per transistor, and delivers h_FE of 120–560 (TR1 PNP) and 100–560 (TR2 NPN), used in discrete logic level translation and push-pull output stages.

For engineers reviewing the PUMZ2 datasheet, PUMZ2 pinout, PUMZ2 application, or PUMZ2 equivalent, key selection criteria include verified dual-transistor thermal coupling in SC-88, matched DC gain across TR1/TR2, low V_CEsat (−500 mV / +250 mV), and compatibility with high-density PCB layouts requiring space-constrained dual-polarity control.

Technical Context

The PUMZ2 integrates one PNP (TR1) and one NPN (TR2) BJT sharing a common substrate, enabling tightly coupled thermal behavior and matched switching timing-critical for complementary emitter-follower or totem-pole driver configurations. Its pinout places base terminals adjacent (pins 2 and 3), facilitating direct gate/base drive routing without cross-coupling traces.

Each transistor operates independently with absolute maximum ratings defined per device: 50 V V_CEO, 150 mA I_C, and 180 mW per-transistor power dissipation at T_amb ≤25 °C. The SOT363 package provides 417 K/W device-level R_th(j-a), supporting stable operation up to 150 °C junction temperature.

FAQ

What is the maximum operating temperature for PUMZ2?

The PUMZ2 has a maximum junction temperature (T_j) of 150 °C and storage temperature range of −65 °C to +150 °C. Its thermal resistance is 417 K/W (device-level) on FR4 PCB at T_amb ≤25 °C, meaning ambient temperature must be limited to ~85 °C to maintain safe junction operation under full 300 mW device dissipation.

Can PUMZ2 be used in linear amplifier mode?

Yes-PUMZ2 supports linear operation with verified h_FE, V_CEsat, and f_T parameters across bias points. Its 120–560 DC gain range and 100–190 MHz transition frequency allow stable Class A or AB amplification up to ~10 MHz, provided thermal design accommodates 180 mW per transistor dissipation.

Is the pinout compatible with other SOT363 double transistors?

No-PUMZ2 uses a unique pin assignment (1: E-TR1, 2: B-TR1, 3: B-TR2, 4: C-TR2, 5: E-TR2, 6: C-TR1). Devices like BC847BDW1T1G use different pinouts (e.g., 1: B-TR1, 2: C-TR1, 3: E-TR1, 4: E-TR2, 5: C-TR2, 6: B-TR2), making them not drop-in replacements without PCB redesign.

Does PUMZ2 support pulsed operation beyond its DC ratings?

Yes-PUMZ2 specifies I_CM = 200 mA peak collector current and I_BM = 100 mA peak base current. These ratings permit short-duration pulses (≤10 μs duty cycle, T_amb ≤25 °C) exceeding DC limits, enabling use in PWM-driven LED dimming or burst-mode power control without derating.
