Nexperia USA Inc. PIMD3,115

Overview

PIMD3 from Nexperia is a dual-channel resistor-equipped transistor (RET) in a single SOT457 (SC-74/TSOP6) package, integrating one NPN and one PNP silicon transistor with built-in 10 kΩ input bias resistors (R1 = R2 = 10 kΩ). It delivers 100 mA output current per channel, supports ±50 V collector-emitter breakdown voltage, and is AEC-Q101 qualified for automotive signal-level switching applications such as I/O buffering and logic-level translation.

For engineers reviewing the PIMD3 datasheet, PIMD3 pinout, PIMD3 application, or PIMD3 equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in digital control interfaces, low-power peripheral drivers, and bidirectional level-shifting circuits where bias resistor matching and thermal coupling matter.

Technical Context

The PIMD3 integrates two complementary RETs-TR1 (NPN) and TR2 (PNP)-in monolithic die configuration within a thermally coupled SOT457 package. Each transistor features matched on-chip base-emitter resistors (R1 = 10 kΩ, R2/R1 = 1.0 typ), enabling direct TTL/CMOS-compatible drive without external bias networks.

It operates across −40 °C to +150 °C junction temperature, with 50 V V_CEO, 100 mA I_O, and typical f_T of 230 MHz (NPN) and 180 MHz (PNP), supporting high-speed digital switching up to ~10 MHz with predictable VI(on)/VI(off) thresholds (1.8–2.5 V on, 0.8–1.1 V off).

FAQ

What is the maximum operating junction temperature for PIMD3?

The absolute maximum junction temperature (T_j) is 150 °C, validated per AEC-Q101 stress testing. Derating begins above 25 °C ambient, with total device power dissipation limited to 400 mW at T_amb ≤ 25 °C on standard FR4 PCB. Thermal resistance R_th(j-a) is 313 K/W under those conditions.

Can PIMD3 replace discrete NPN+PNP transistor pairs in existing designs?

Yes-PIMD3 directly replaces two discrete transistors plus four bias resistors in complementary switching circuits. Pin mapping matches common SOT-363 layouts with functional equivalence: pins 1/2/6 replicate NPN operation; pins 3/4/5 replicate PNP operation. Layout adaptation is minimal due to identical SOT457 footprint.

Is the R1/R2 resistor ratio tightly controlled across temperature?

R2/R1 ratio is specified 0.8–1.2 at 25 °C, and process-matched resistors track within ±15% over −40 °C to +125 °C per characterization data. This ensures consistent VI(on)/VI(off) hysteresis and switching symmetry between TR1 and TR2 across full automotive temperature range.

Does PIMD3 support 1.8 V logic-level input drive?

No-VI(on) is 1.8–2.5 V (TR1) and −1.8 to −2.5 V (TR2), making it compatible with 3.3 V and 5 V logic families but not guaranteed for reliable turn-on with 1.8 V CMOS outputs. For 1.8 V systems, a logic buffer or level shifter is recommended before the PIMD3 inputs.
