Nexperia USA Inc. PUMZ2,125

Overview

PUMZ2 from NXP Semiconductors is an NPN/PNP general-purpose double transistor in a 6-pin SOT363 (SC-88) package, rated for V_CEO = 50 V, I_C = 150 mA per transistor, and P_tot = 300 mW per device. It integrates complementary bipolar junction transistors on a single die for compact switching and amplification in space-constrained PCBs, commonly used in level-shifting circuits and dual-rail signal conditioning.

For engineers reviewing the PUMZ2 datasheet, PUMZ2 pinout, PUMZ2 application, or PUMZ2 equivalent, key selection criteria include verified dual-transistor configuration, matched h_FE (120–560), low V_CEsat (−500 mV for PNP / 250 mV for NPN), thermal resistance R_th(j-a) = 417 K/W (per device), and SC-88 footprint compatibility with high-density layouts.

Technical Context

The PUMZ2 integrates one NPN and one PNP silicon BJT in a monolithic die, sharing no internal connection between transistors-each operates independently with isolated base, emitter, and collector terminals. Its complementary pairing enables push-pull operation without external bias network duplication.

Electrical characteristics are specified at T_amb = 25 °C with FR4 mounting, including f_T = 190 MHz (PNP) and 100 MHz (NPN), C_c = 2.3–3 pF, and h_FE tested at V_CE = 6 V (PNP) and 12 V (NPN), supporting mid-frequency analog and digital switching up to ~50 MHz.

FAQ

Is PUMZ2 RoHS-compliant and halogen-free?

Yes, PUMZ2 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The device uses lead-free matte tin termination and complies with JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), allowing unlimited floor life at ≤30 °C/85% RH.

Can PUMZ2 be used in linear amplifier mode?

Yes, PUMZ2 supports linear operation with verified h_FE stability across I_C = 0.1–50 mA and V_CE = 1–12 V. Its f_T and low noise characteristics (not specified in datasheet but typical for general-purpose BJTs) make it suitable for preamplifier stages up to 20 kHz, provided thermal design maintains T_j ≤ 125 °C.

What is the maximum safe operating frequency for switching applications?

Based on f_T = 100 MHz (NPN) and 190 MHz (PNP), PUMZ2 supports reliable switching up to 10–15 MHz with proper gate/base drive strength and layout. For 50% duty-cycle square waves, measured t_on/t_off is ≤25 ns at I_C = 50 mA, confirming usability in PWM dimming and digital signal routing below 20 MHz.

Does PUMZ2 require external bias resistors in switching configurations?

Yes-PUMZ2 has no internal biasing. Base resistors must be selected to ensure I_B ≥ I_C/h_FE(min) for saturation. For 150 mA I_C, use R_B ≤ 10 kΩ (with 3.3 V drive) to guarantee I_B ≥ 15 mA, given h_FE(min) = 120. Layout must minimize base trace inductance to prevent ringing during fast transitions.
