Product details
Overview
PIMP31-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 = 1 kΩ and R2/R1 = 10 bias resistors; used for digital switching and IC input control in automotive ECUs and body electronics.
For engineers reviewing the PIMP31-QX datasheet, PIMP31-QX pinout, PIMP31-QX application, or PIMP31-QX equivalent, this page delivers verified electrical parameters, validated AEC-Q101 qualification status, confirmed thermal derating behavior on FR4 PCB, and precise dual-transistor bias network configuration for direct circuit integration.
Technical Context
The PIMP31-QX integrates two matched PNP transistors with monolithically embedded base bias resistors-R1 (1 kΩ) connected between input and base, R2 (10 kΩ) between base and emitter-enabling single-resistor drive logic-level switching without external bias components. Each transistor operates independently with open-base VCEO = −50 V and IO = −500 mA rating.
It supports automotive-grade operation across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C and qualified per AEC-Q101. Thermal resistance is 298 K/W (per device, junction-to-ambient on FR4), enabling stable performance in space-constrained modules with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with base open; defines high-side switch blocking capability in 24 V automotive systems. |
| IO | −500 mA: Continuous DC output current per transistor; supports driving relays, LEDs, or logic inputs without external current amplification. |
| R1 | 1 kΩ (0.7–1.3 kΩ): Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL logic levels. |
| R2/R1 | 10 (9–11): Fixed feedback ratio; ensures stable saturation and prevents thermal runaway during sustained conduction. |
| Ptot (per device) | 420 mW at Tamb ≤ 25 °C: Total power dissipation limit on standard FR4 PCB; enables compact layout without forced air cooling. |
| hFE | 70 min at VCE = −5 V, IC = −50 mA: Minimum DC current gain; guarantees reliable saturation under worst-case load conditions. |
| VCE(sat) | −100 mV max at IC = −50 mA, IB = −2.5 mA: Low saturation voltage; minimizes power loss and heat generation in high-duty-cycle switching. |
Pinout & Package
SOT457 (SC-74/TSOP6) surface-mount plastic package: 6-pin, 3.0 mm × 1.7 mm footprint, 0.65 mm pitch, 0.95 mm height; optimized for reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter of TR1; common reference node for first transistor's current path. |
| 2 | I1 | Input (base) of TR1; accepts logic-level signal through internal R1 resistor. |
| 3 | O2 | Collector of TR2; active-high switched output node for second transistor. |
| 4 | GND2 | Emiter of TR2; independent ground return for second transistor's load current. |
| 5 | I2 | Input (base) of TR2; driven separately from I1, enabling dual independent switching control. |
| 6 | O1 | Collector of TR1; primary high-side switched output with low VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully isolated PNP transistors with dedicated bias networks-enables compact dual-channel switching without discrete resistor placement. |
| AEC-Q101 qualification | Stress-tested for automotive use including temperature cycling, HTRB, and ESD; supports deployment in engine control, lighting, and ADAS modules. |
| Integrated R1/R2 bias network | R1 = 1 kΩ ±30 %, R2/R1 = 10 ±10 %; eliminates external bias components and reduces BOM count by up to 4 parts per channel. |
| Low VCE(sat) | ≤ −100 mV at IC = −50 mA; reduces conduction loss by >60 % versus standard BC807-Q series in same application. |
| Thermal robustness | Rth(j-a) = 298 K/W (per device on FR4); sustains full 500 mA load at 85 °C ambient without derating in typical PCB 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 |
|---|---|---|---|
| BC807-Q-16 | Single PNP transistor; no integrated bias resistors; requires external R1/R2 for each channel. | Higher component count and layout area; not qualified to AEC-Q101. | Select when cost sensitivity outweighs space constraints and automotive qualification is unnecessary. |
| PIMN31 | NPN/NPN complement; identical package and bias ratios but opposite polarity; VCEO = +50 V, IO = +500 mA. | Used where low-side switching or inverted logic is required; incompatible for high-side PNP configurations. | Select for complementary NPN-based designs or mixed-signal boards requiring both polarities in same footprint. |
Compared with BC807-Q-16, PIMP31-QX reduces bill-of-materials and layout complexity while adding AEC-Q101 reliability; compared with PIMN31, it provides native high-side switching capability essential for automotive power domain isolation.

FAQ
What is the maximum continuous current per transistor in the PIMP31-QX?
The PIMP31-QX supports −500 mA continuous DC output current per transistor under Tamb ≤ 25 °C with standard FR4 PCB mounting. Derating begins at 2.8 mW/°C above 25 °C ambient, reaching zero at 175 °C per the published power derating curve.
Can the two transistors be used with independent control signals?
Yes - pins I1 (pin 2) and I2 (pin 5) are electrically isolated inputs, each feeding its own transistor's base through dedicated R1 resistors. GND1 (pin 1) and GND2 (pin 4) are separate emitter returns, enabling fully independent switching of two loads with no shared current path.
Is the PIMP31-QX pin-compatible with the PIMN31 or PIMC31?
No - although all three share the SOT457 package and 6-pin layout, their internal connectivity differs: PIMP31-QX has dual PNP topology with GND1/I1/O1/GND2/I2/O2 pin order, while PIMN31 (NPN/NPN) and PIMC31 (NPN/PNP) assign different functions to pins 1–6 and require schematic redesign for substitution.
Does the PIMP31-QX require external pull-down resistors on its input pins?
No - the internal R2 resistor (10 kΩ) connects each transistor's base to its emitter, providing inherent pull-down functionality. This ensures defined OFF-state behavior when I1 or I2 is left floating or driven high-impedance, eliminating need for external pull-downs in most digital interface applications.
