Nexperia USA Inc. PIMD2,125

Overview

PIMD2 from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP silicon bipolar transistor with built-in bias resistors (R1 = R2 = 22 kΩ) in a single TSOP6 (SOT457) package. It delivers 100 mA output current per transistor, supports ±50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal-level switching applications such as digital I/O buffering and low-current peripheral control.

For engineers reviewing the PIMD2 datasheet, PIMD2 pinout, PIMD2 application, or PIMD2 equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in logic-level interface circuits where simplified biasing, reduced pick-and-place count, and automotive-grade reliability are required.

Technical Context

The PIMD2 integrates two complementary bipolar transistors-TR1 (NPN) and TR2 (PNP)-each with monolithically integrated base bias resistors (R1, R2), enabling direct connection to CMOS/TTL logic without external bias networks. Its dual-transistor topology supports push-pull or complementary switching configurations.

Each transistor operates independently with separate emitter (GND1/GND2), base (I1/I2), and collector (O1/O2) terminals. The built-in resistors provide fixed current gain setting (hFE ≈ 60 at IC = 5 mA) and ensure stable on/off behavior across −40 °C to +150 °C junction temperature range.

FAQ

What is the maximum operating temperature for PIMD2 in continuous use?

The PIMD2 has a maximum junction temperature (T_j) of 150 °C and is rated for ambient temperatures from −55 °C to +150 °C. When mounted on a standard FR4 PCB with 35 μm copper, its thermal resistance is 313 K/W, allowing continuous operation up to +105 °C ambient at full 100 mA load without exceeding T_j limits.

Can PIMD2 be used in a push-pull output stage without additional components?

Yes. With independent NPN (TR1) and PNP (TR2) sections, each with dedicated base inputs (I1, I2) and collectors (O1, O2), the PIMD2 supports true complementary push-pull operation. Driving I1 high and I2 low simultaneously activates both transistors for rail-to-rail output swing, requiring no external bias resistors or level shifters.

How does the built-in resistor ratio affect switching performance?

The R2/R1 ratio of 1.0 ±0.2 ensures matched base current injection for both transistors, resulting in symmetrical turn-on/turn-off timing and consistent V_CE(sat). This ratio stabilizes h_FE across temperature and process variation, reducing timing skew in dual-edge-sensitive applications like clock distribution or data strobing.

Is PIMD2 pin-compatible with other TSOP6 RETs like PEMD2 or PUMD2?

No. While all share the TSOP6 (SOT457) footprint, PIMD2 has unique pin assignment: GND2–I2–O1–GND1–I1–O2. PEMD2 uses GND–I1–O1–I2–O2–GND, and PUMD2 differs further. Direct substitution requires PCB layout revision; functional equivalence must be verified per circuit role, not pinout.
