Product details
Overview
PIMP32-QX from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT457 (SC-74/TSOP6) package, rated for −50 V VCEO, −500 mA output current per transistor, with integrated R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors. It functions as a compact, AEC-Q101-qualified switching pair for digital load control and IC input driving in automotive body electronics.
For engineers reviewing the PIMP32-QX datasheet, PIMP32-QX pinout, PIMP32-QX application, or PIMP32-QX equivalent, this device serves as a drop-in replacement for BC807-Q series in space-constrained digital switching circuits requiring reduced BOM count, simplified base drive, and automotive-grade reliability.
Technical Context
The PIMP32-QX integrates two matched PNP transistors with on-chip base bias networks-R1 (2.2 kΩ) connected between input and base, R2 (10 kΩ) between base and emitter-enabling single-resistor logic-level drive without external components. Each transistor operates independently with open-base VCEO = −50 V and IO = −500 mA rating.
Its thermal design supports 420 mW total power dissipation at Tamb ≤ 25 °C on FR4 PCB, with Rth(j-a) = 298 K/W (per device) and Rth(j-sp) = 105 K/W, enabling stable operation in ambient temperatures from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | −500 mA - Continuous output current per transistor; sufficient for driving relays, LEDs, or logic inputs directly. |
| R1 | 2.2 kΩ - Input bias resistor value; sets base current for predictable turn-on with 3.3 V or 5 V logic. |
| R2/R1 ratio | 4.55 - Ensures stable saturation and low VCE(sat) ≤ −100 mV at IC = −50 mA / IB = −2.5 mA. |
| hFE | 70 min - DC current gain at VCE = −5 V, IC = −50 mA; guarantees reliable switching across −40 °C to +100 °C. |
| Ptot (device) | 420 mW - Total power dissipation limit on standard FR4 PCB; defines thermal headroom for dual-transistor operation. |
| AEC-Q101 qualified | Yes - Validated for automotive applications including engine control modules, lighting, and body control units. |
Pinout & Package
Package: SOT457 (SC-74 / TSOP6), 6-pin surface-mount plastic package with 0.95 mm pitch, 3.0 × 1.7 mm footprint, and exposed pad-compatible layout per Fig. 12–13.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter of TR1; common reference node for first transistor's current path. |
| 2 | I1 | Base input of TR1; driven through internal R1; accepts logic-level signals directly. |
| 3 | O2 | Collector of TR2; active-high sink output when TR2 is switched on. |
| 4 | GND2 | Emiter of TR2; independent ground return for second transistor. |
| 5 | I2 | Base input of TR2; isolated from I1; enables independent control of both transistors. |
| 6 | O1 | Collector of TR1; active-high sink output; complements O2 for dual-load switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with dedicated bias networks eliminate need for 4 external resistors in typical switch designs. |
| Automotive qualification | AEC-Q101 certified for temperature cycling, humidity, and mechanical stress-validated for under-hood and cabin modules. |
| Logic-compatible input threshold | VI(on) = −0.95 V typ. at IC = −20 mA ensures robust turn-on with 3.3 V CMOS outputs without level-shifting. |
| Low saturation voltage | VCE(sat) ≤ −100 mV at IC/IB = 20 guarantees minimal power loss and heat generation during conduction. |
| Thermal performance | Rth(j-sp) = 105 K/W enables efficient heat transfer to PCB copper, supporting sustained 500 mA operation in compact layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN32-Q | NPN/NPN complement; same package, R1/R2 values, and ratings but opposite polarity. | Required where active-high sourcing (vs. sinking) is needed for pull-up or high-side driver configurations. | Select when interfacing with open-collector logic or driving N-channel MOSFET gates. |
| BC807-Q-16 | Single PNP transistor; no integrated bias resistors; requires external RB and RBE; lower IO = −100 mA. | Used in lower-current, non-automotive applications where discrete tuning of bias is preferred. | Choose only if design requires adjustable base current or operates outside AEC-Q101 scope. |
Compared with PIMN32-Q, PIMP32-QX offers complementary polarity for bidirectional signal conditioning; versus BC807-Q-16, it delivers 5× higher current, integrated biasing, and automotive qualification-making it superior for compact, high-reliability dual-switching nodes.

FAQ
What is the maximum junction temperature and how does it affect continuous operation?
The PIMP32-QX has a maximum junction temperature (Tj) of 150 °C. With Rth(j-a) = 298 K/W on FR4 PCB, continuous operation at full 500 mA per transistor requires ambient temperature ≤ 65 °C to stay within thermal limits. Derating curves in Figure 1 confirm 420 mW total device dissipation at 25 °C ambient, decreasing linearly above that point.
Can PIMP32-QX drive inductive loads like relays or solenoids directly?
Yes-each transistor supports −500 mA continuous current and −50 V VCEO, making it suitable for driving 12 V/24 V automotive relays and small solenoids. For inductive loads, a flyback diode must be placed externally across the load; the device itself does not integrate clamp protection.
How does the R2/R1 ratio of 4.55 impact switching behavior?
The R2/R1 ratio determines base-emitter feedback strength: a ratio of 4.55 ensures deep saturation (VCE(sat) ≤ −100 mV) while maintaining fast turn-off via R2-assisted charge removal. This ratio balances low conduction loss with reliable cutoff-critical for PWM-driven loads and noise-immune digital interfaces.
Is the marking code "4J" unique to PIMP32-QX and verifiable on the physical package?
Yes-Table 4 confirms "4J" is the official top-side marking for PIMP32-QX. This 2-character code is laser-etched on the package body and matches Nexperia's standardized marking scheme for SC-74 RET devices; it is used for traceability and counterfeit prevention in automotive supply chains.
