Product details
Overview
PIMC32X from Nexperia is a dual NPN/PNP resistor-equipped transistor (RET) in SOT457 (SC-74/TSOP6) package, integrating two complementary bipolar transistors with built-in bias resistors R1 = 2.2 kΩ and R2 = 10 kΩ. It delivers 500 mA per transistor, supports 50 V VCEO, and serves as a compact, low-component-count switching solution for digital logic interfacing and load control in space-constrained PCBs.
For engineers reviewing the PIMC32X datasheet, PIMC32X pinout, PIMC32X application, or PIMC32X equivalent, this device is selected for its integrated bias network, dual-polarity output capability, thermal performance on FR4 (Rth(j-a) = 298 K/W per device), and direct replacement suitability for BC807/BC817-based digital switch designs requiring reduced BOM count and simplified layout.
Technical Context
The PIMC32X integrates one NPN (TR1) and one PNP (TR2) transistor sharing a common bias-resistor architecture: R1 connects each base to its input, while R2 provides base-emitter feedback. Each transistor operates independently with separate collector and emitter terminals, enabling push-pull or complementary switching without external bias components.
It supports bidirectional logic-level drive: TR1 (NPN) switches loads referenced to ground with VI(on) = 0.95 V (typ) at IC = 20 mA; TR2 (PNP) switches high-side loads with VI(on) = −0.95 V (typ) under symmetric conditions. Both transistors maintain hFE ≥ 70 at IC = 50 mA and exhibit fT of 225 MHz (TR1) and 140 MHz (TR2), confirming suitability for medium-speed digital switching up to ~50 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial logic and 3.3/5 V microcontroller I/O buffering. |
| IO | 500 mA - Continuous DC output current per transistor; supports driving relays, LEDs, small solenoids, or logic inputs directly. |
| R1 | 2.2 kΩ ±30% - Input bias resistor value; sets base current for predictable turn-on without external resistor calculation. |
| R2/R1 ratio | 4.55 (typ) - Feedback resistor ratio ensuring stable saturation and consistent VI(on)/VI(off) thresholds across temperature. |
| Ptot (per device) | 420 mW at Tamb ≤ 25 °C - Total power dissipation limit; defines thermal derating envelope for dual-transistor operation on standard FR4 PCB. |
| hFE | ≥70 at VCE = 5 V, IC = 50 mA - Minimum DC current gain; guarantees reliable saturation with ≤2.5 mA base drive for 50 mA collector load. |
| VCE(sat) | ≤100 mV at IC = 50 mA, IB = 2.5 mA - Low saturation voltage ensures minimal conduction loss and heat generation in switching applications. |
Pinout & Package
SOT457 (SC-74/TSOP6) surface-mount plastic package: 6-pin, 1.7 mm × 2.5 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering with standardized land pattern (3.45 mm × 1.95 mm).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); must be tied to system ground for proper NPN operation. |
| 2 | I1 | Base input for TR1 (NPN); accepts positive logic signal to enable low-side switching. |
| 3 | O2 | Collector output for TR2 (PNP); connects to load's high-side terminal for sourcing current. |
| 4 | GND2 | Emiter connection for TR2 (PNP); ties to system VCC rail to complete PNP current path. |
| 5 | I2 | Base input for TR2 (PNP); accepts inverted or negative logic to enable high-side switching. |
| 6 | O1 | Collector output for TR1 (NPN); connects to load's low-side terminal for sinking current. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-polarity integration | Single SOT457 package contains matched NPN + PNP transistors with shared resistor network-eliminates discrete pairing mismatch and saves 5 mm² board area. |
| Built-in bias network | R1 = 2.2 kΩ and R2 = 10 kΩ resistors are laser-trimmed on-die-removes need for 4 external resistors and reduces placement error risk in automated assembly. |
| Thermal robustness | Rth(j-a) = 298 K/W (per device) on standard FR4-supports sustained 300 mW dissipation without heatsink in ambient ≤70 °C environments. |
| Logic-compatible thresholds | VI(on) = 0.65 V (typ) for TR1 and −0.65 V (typ) for TR2-ensures clean turn-on with 3.3 V and 5 V CMOS/TTL outputs without level-shifting. |
| Low saturation loss | VCE(sat) ≤ 100 mV at 50 mA-limits power loss to <5 mW per transistor, critical for battery-powered or thermally constrained modules. |
Applications
| Industrial Digital I/O Expansion | Microcontroller GPIO Buffering |
|---|---|
Use Scenario: Adding isolated sink/source capability to PLC I/O modules using limited PCB real estate. IC Role / Device Role / Timing Role: Dual RET acts as compact, resistorless interface between MCU GPIO and 24 V field devices (sensors, indicators). Use Value: Reduces component count by 4 resistors and 1 transistor per channel versus discrete BC817+BC807 pair, cutting BOM cost by ~$0.015/unit at volume. |
Use Scenario: Protecting low-current MCU pins from overcurrent when driving LED arrays or small relays. IC Role / Device Role / Timing Role: TR1 sinks LED current; TR2 sources current to active-low logic inputs-enabling bidirectional signal conditioning. Use Value: VI(on) ≤ 0.95 V ensures full turn-on with 3.3 V MCU outputs; VCE(sat) ≤ 100 mV limits self-heating during continuous LED drive. |
| Consumer Appliance Control Panel | Automated Test Equipment (ATE) Signal Switching |
Use Scenario: Driving tactile feedback LEDs and buzzer drivers in white-goods control boards where EMI and layout density matter. IC Role / Device Role / Timing Role: PIMC32X replaces two separate RETs (e.g., PIMN32 + PIMP32), reducing routing congestion near front-panel connectors. Use Value: Integrated R1/R2 matching ensures symmetrical rise/fall times (<100 ns typical) across both transistors-minimizing audible buzz in piezo drivers. |
Use Scenario: Multiplexing test signals between DUT and measurement instruments in modular ATE fixtures. IC Role / Device Role / Timing Role: Functions as a fast, low-leakage analog switch driver-TR1/TR2 jointly control MOSFET gates or relay coils in sequence. Use Value: ICEO ≤ 0.5 µA and ICBO ≤ 100 nA ensure <1 µA leakage in off-state-critical for precision leakage current testing of semiconductor DUTs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-polarity resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN32 | NPN/NPN configuration only; no PNP element; identical R1/R2 values and SOT457 package. | Limited to low-side switching only; cannot replace PIMC32X in push-pull or high-side load circuits. | Select only when dual NPN functionality suffices and high-side drive is unnecessary. |
| BC807-40/BC817-40 pair | Discrete transistors requiring four external bias resistors; no integrated R1/R2 network; same hFE grade but higher layout overhead. | Higher assembly cost and larger footprint; requires careful resistor matching to replicate PIMC32X's VI(on)/VI(off) consistency. | Choose only if legacy design reuse or parametric fine-tuning (e.g., custom R1/R2 values) is required. |
Compared with PIMN32, PIMC32X adds essential PNP functionality for high-side control; compared with discrete BC807/BC817 pairs, it cuts PCB area by 40%, eliminates 4 passives, and guarantees resistor matching-making it optimal for new designs prioritizing miniaturization and assembly yield.

FAQ
What is the maximum operating temperature for continuous use of PIMC32X?
The PIMC32X has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. For continuous operation at full 500 mA per transistor, ambient temperature must remain ≤70 °C on standard FR4 PCB due to thermal derating-power dissipation drops linearly above 25 °C per Fig. 1 (420 mW → 0 mW at 175 °C).
Can PIMC32X replace BC807 and BC807-25 in existing designs without layout changes?
No-PIMC32X uses SOT457 (6-pin TSOP6) while BC807 variants use SOT23 (3-pin). Pin compatibility is not maintained; redesign is required to accommodate the 6-pin footprint and revised pin functions (e.g., separate GND1/GND2, dual outputs). However, schematic-level substitution is straightforward: connect I1/O1 for NPN function and I2/O2/GND2 for PNP function.
How does the built-in R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 4.55 (typ) establishes fixed base-emitter feedback that stabilizes VI(on) at 0.95 V and VI(off) at 0.65 V across temperature, ensuring consistent turn-on threshold and preventing partial conduction. This eliminates sensitivity to VBE drift and removes need for external feedback tuning-critical for reliable operation in wide-temperature industrial environments.
Is PIMC32X qualified for automotive applications?
No-PIMC32X is not AEC-Q101 qualified and is explicitly designated for industrial and consumer applications per Nexperia's legal disclaimers. It lacks automotive-grade screening, extended temperature validation beyond 150 °C ambient, and zero-defect manufacturing controls required for automotive use. For automotive designs, consult Nexperia's AEC-Q101-certified RET portfolio (e.g., PUMD12).
