Nexperia USA Inc. PIMT1,115

Overview

PIMT1 from Nexperia is a PNP general-purpose double transistor in a SOT457 (TSOP6) surface-mount package, configured as two independent PNP transistors sharing no internal connection. It supports V_CEO = −40 V, I_C = −100 mA per device, h_FE = 120 (at V_CE = −6 V, I_C = −1 mA), and is AEC-Q101 qualified for automotive-grade reliability. It is used in compact dual-switching circuits such as LED driver pairs or complementary logic-level translators.

For engineers reviewing the PIMT1 datasheet, PIMT1 pinout, PIMT1 application, or PIMT1 equivalent, key selection criteria include dual-PNP topology in a 6-pin TSOP6 footprint, low-voltage/low-current switching capability, thermal resistance of 208 K/W on FR4, and automotive qualification status - all critical for space-constrained, thermally managed, and automotive-compliant designs.

Technical Context

The PIMT1 integrates two electrically isolated PNP bipolar junction transistors in a single monolithic die housed in a SOT457 plastic package. Each transistor operates independently with identical absolute maximum ratings: V_CEO = −40 V, I_C = −100 mA, and P_tot = 300 mW at T_amb ≤ 25 °C.

Its DC current gain h_FE is specified at 120 (min) under V_CE = −6 V and I_C = −1 mA, while V_CE(sat) reaches −200 mV at I_C = −50 mA / I_B = −5 mA (pulsed). Transition frequency f_T is 100 MHz at V_CE = −12 V, I_C = −2 mA, confirming suitability for low-frequency switching and audio amplification.

FAQ

Is the PIMT1 pin-compatible with other dual-transistor packages like SOT363?

No. The PIMT1 uses the SOT457 (TSOP6) package with a unique 1–2–3–4–5–6 pin order: E1–B1–C2–E2–B2–C1. SOT363 has different pin mapping (e.g., E–B–C for each transistor in sequence) and smaller dimensions. Mechanical and electrical incompatibility means direct replacement requires PCB redesign.

What is the maximum allowable continuous power dissipation per transistor?

The PIMT1 has a total P_tot rating of 300 mW at T_amb ≤ 25 °C on FR4 with a 1 cm² collector pad. Since it contains two independent transistors, each can dissipate up to 150 mW continuously under balanced loading - assuming equal current distribution and no thermal coupling beyond datasheet test conditions.

Does the AEC-Q101 qualification cover both transistors simultaneously under stress?

Yes. Nexperia's AEC-Q101 qualification applies to the entire PIMT1 device, including both transistors operating concurrently under temperature cycling, humidity bias, and HTRB stress tests. The qualification report confirms functionality and parametric stability for the full dual-transistor structure, not just individual elements.

Can the PIMT1 be used in linear amplification mode with stable bias?

Yes. With h_FE ≥ 120 at I_C = −1 mA and f_T = 100 MHz, the PIMT1 supports stable Class-A or AB biasing in audio preamplifier stages. Designers must ensure V_CE remains > −1 V and I_C stays within −100 mA to avoid second breakdown, using the provided thermal resistance to manage junction temperature.
