Nexperia USA Inc. PIMZ2,125

Overview

PIMZ2 from NXP Semiconductors is an NPN/PNP general-purpose double transistor in SOT457 (SC-74) package, integrating complementary bipolar junction transistors on a single die. It delivers V_CEO = 50 V, I_C = 150 mA per transistor, and h_FE = 120–560 (TR1 PNP at V_CE = 6 V, I_C = 1 mA), enabling compact dual-polarity switching and amplification in space-constrained PCBs.

For engineers reviewing the PIMZ2 datasheet, PIMZ2 pinout, PIMZ2 application, or PIMZ2 equivalent, this device supports simplified BOM consolidation for discrete logic-level translation, push-pull output stages, and bidirectional signal conditioning where matched thermal tracking and shared substrate benefits are required.

Technical Context

The PIMZ2 integrates one PNP (TR1) and one NPN (TR2) transistor sharing a common thermal environment and substrate, enabling precise complementary operation without inter-device thermal drift. TR1 exhibits V_CEsat = −500 mV at I_C = −50 mA / I_B = −5 mA; TR2 achieves V_CEsat = 250 mV at I_C = 50 mA / I_B = 5 mA - supporting low-loss switching in totem-pole configurations.

Its f_T of 190 MHz (TR1) and 100 MHz (TR2), combined with C_c ≤ 3 pF (TR2) and ≤ 5 pF (TR1), supports stable small-signal amplification up to VHF range. The device operates across T_amb = −65 °C to +150 °C and maintains h_FE consistency due to monolithic construction.

FAQ

What is the maximum continuous collector current per transistor in the PIMZ2?

The PIMZ2 supports a maximum DC collector current of 150 mA per transistor under normal operating conditions (T_amb ≤ 25 °C). At elevated ambient temperatures, derating applies per the thermal resistance R_th(j-a) = 417 K/W (per device), limiting usable current to ~100 mA at 70 °C ambient.

Can the PIMZ2 replace discrete PNP and NPN transistors in existing push-pull designs?

Yes - the PIMZ2 is designed as a direct functional replacement for discrete complementary pairs. Its pinout maps TR1 (PNP) and TR2 (NPN) collectors/emitters/bases to dedicated pins, enabling drop-in substitution in schematics that assign separate transistors to high-side and low-side roles.

Does the PIMZ2 require external base resistors when driven by a 3.3 V MCU GPIO?

Yes - base resistors are required to limit I_B and ensure saturation. For TR2 (NPN), a 2.2 kΩ resistor limits I_B to ~1.2 mA at 3.3 V, sufficient for 50 mA I_C. For TR1 (PNP), a 2.2 kΩ resistor from GPIO to base yields ~1.2 mA I_B when GPIO is low (0 V), enabling full turn-on with V_EB ≈ 0.7 V.

Is the PIMZ2 suitable for automotive under-hood applications?

No - while rated for T_j = 150 °C and T_amb = −65 °C to +150 °C, the PIMZ2 is not AEC-Q101 qualified. It lacks automotive-specific stress testing (e.g., HTOL, temperature cycling) and is intended for industrial, consumer, and commercial applications per NXP's product status documentation.
