Product details
Overview
PIMN32-QX from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT457 (SC-74/TSOP6) package, rated for 50 V VCEO, 500 mA per transistor output current, with integrated R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors. It functions as a compact, AEC-Q101-qualified digital switching pair for automotive control logic and IC input driving.
For engineers reviewing the PIMN32-QX datasheet, PIMN32-QX pinout, PIMN32-QX application, or PIMN32-QX equivalent, this device serves as a drop-in replacement for BC817-based dual-transistor circuits where space, BOM count, and automotive-grade reliability are critical.
Technical Context
The PIMN32-QX integrates two matched NPN transistors with on-die base bias networks-R1 connected between input and base, R2 between base and emitter-enabling single-resistor drive per channel. Each transistor operates independently with open-base VCEO = 50 V and IO = 500 mA rating.
Its SC-74 package supports high-density SMT placement and delivers Rth(j-a) = 298 K/W (per device) on FR4 PCBs. Thermal derating begins at Tamb > 25 °C, with full power (420 mW) only at ambient ≤25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe switching range for 24 V automotive loads. |
| IO | 500 mA - Continuous DC output current per transistor; supports relay coils, LED strings, and logic-level MOSFET gates. |
| R1 | 2.2 kΩ ±30% - Input bias resistor enabling direct microcontroller GPIO drive without external components. |
| R2/R1 | 4.55 - Fixed internal ratio setting base current division; ensures stable saturation under varying temperature. |
| hFE | 70 min - DC current gain at IC = 50 mA, VCE = 5 V; sufficient for robust digital switching with margin. |
| VCE(sat) | 100 mV max - Low saturation voltage at IC = 50 mA, IB = 2.5 mA; minimizes conduction loss and self-heating. |
| fT | 225 MHz typ - Transition frequency of internal transistors; supports fast edge rates in digital signal routing. |
Pinout & Package
SOT457 (SC-74/TSOP6) 6-pin surface-mount plastic package, 3.0 mm × 1.7 mm footprint, 0.95 mm height, lead pitch 0.65 mm. Designed for reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference for first transistor's output path. |
| 2 | I1 | Input terminal for TR1 base; accepts logic-level drive (VI(on) = 0.95 V typ). |
| 3 | O2 | Collector output of TR2; switches load referenced to GND2 or floating supply rail. |
| 4 | GND2 | Emiter connection for TR2; independent ground node enabling dual isolated switching paths. |
| 5 | I2 | Input terminal for TR2 base; electrically isolated from I1 but shares same bias topology. |
| 6 | O1 | Collector output of TR1; complements O2 for dual-channel load control with separate emitters. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two independent, resistor-equipped NPN transistors in one 6-pin package-replaces two discrete BC817 + four resistors. |
| AEC-Q101 qualification | Qualified for automotive applications including engine control modules and body electronics per stress test standard. |
| Integrated R1/R2 network | Eliminates need for external base resistors; reduces PCB area by ≥40% and assembly steps by two placements per channel. |
| Thermal performance | Per-device Ptot = 420 mW at Tamb = 25 °C with Rth(j-a) = 298 K/W-supports sustained operation in sealed enclosures. |
| Input voltage tolerance | VI input range −5 V to +12 V enables compatibility with 3.3 V, 5 V, and 12 V logic families without level-shifting. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC817-16DW | Discrete dual NPN in SOT363; no built-in resistors-requires four external bias resistors. | Higher BOM count and layout complexity; not AEC-Q101 qualified. | Select when design requires adjustable base current or non-standard R1/R2 values. |
| PIMN32-Q | Same die and package; identical electrical specs-QX is the tape-and-reel variant of Q. | No functional difference; QX denotes packaging format (reel), not performance. | Choose PIMN32-QX for automated SMT production; PIMN32-Q for sample evaluation or manual prototyping. |
Compared with BC817-16DW, PIMN32-QX reduces component count by 4× and qualifies for automotive use; versus PIMN32-Q, it offers identical performance with optimized reel packaging for high-volume placement.

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) is 150 °C per the datasheet limiting values table. Operation above this threshold risks permanent degradation. Derating is required above Tamb = 25 °C per the published power derating curve-e.g., at 85 °C ambient, maximum per-device power drops to ~220 mW.
Can PIMN32-QX drive inductive loads directly?
Yes-each transistor supports 500 mA DC current and has VCEO = 50 V, making it suitable for relays, solenoids, and small motors. However, an external flyback diode must be placed across the inductive load to clamp reverse EMF and prevent VCE overshoot beyond 50 V.
Is there crosstalk between the two transistors?
No measurable functional crosstalk exists-the transistors share only substrate and package thermal mass. Electrical isolation is maintained: GND1 and GND2 are separate terminals, and inputs I1/I2 have independent bias networks. Measured inter-transistor leakage is <100 nA at VCB = 50 V.
What does the marking '4G' indicate on the device top?
The marking '4G' is the manufacturer's traceable code for PIMN32-QX per Table 4 of the datasheet. It identifies the specific wafer lot, assembly site, and date code-enabling full traceability for automotive PPAP and quality audits. It is not a functional or parametric identifier.
