Product details
Overview
PIMC32PA from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in a DFN2020-6 (SOT1118) leadless SMD package, rated for 50 V VCEO and 500 mA output current per transistor, with integrated R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors. It serves as a compact, dual-polarity switching element for digital control interfaces and load switching in space-constrained PCBs.
For engineers reviewing the PIMC32PA datasheet, PIMC32PA pinout, PIMC32PA application, or PIMC32PA equivalent, this device offers verified dual-transistor functionality with built-in biasing-enabling direct drive of logic inputs, level translation between 3.3 V/5 V domains, and complementary switching without external resistors.
Technical Context
The PIMC32PA integrates one NPN (TR1) and one PNP (TR2) transistor sharing no internal connection between their collectors or emitters-each operates independently with dedicated base resistors. TR1 exhibits fT = 210 MHz and hFE ≥ 70 at IC = 50 mA; TR2 delivers fT = 150 MHz and comparable DC gain under negative polarity conditions.
Its resistor network enables fixed-current drive: R1 sets base current while R2/R1 = 4.55 provides stable bias ratio across temperature (−40 °C to 150 °C). The device supports bidirectional signal conditioning-TR1 sinks current from high-side logic, TR2 sources current to low-side loads-with VCE(sat) ≤ 100 mV at IC/IB = 20.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 3.3/5 V logic interfacing with margin. |
| IO | 500 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic gate inputs without heatsinking. |
| R1 | 2.2 kΩ ±30% - Input bias resistor for each transistor; sets base current directly from MCU GPIO or logic output. |
| R2/R1 | 4.55 - Fixed bias ratio ensuring stable saturation under varying temperature and process variation. |
| VCE(sat) | ≤100 mV at IC = 50 mA, IB = 2.5 mA - Low saturation voltage minimizes power loss and heat generation during switching. |
| fT (TR1) | 210 MHz - Transition frequency enabling reliable operation up to ~20 MHz digital switching with controlled edge rates. |
| Package | DFN2020-6 (SOT1118) - 2 mm × 2 mm × 0.65 mm thermally enhanced leadless package with 0.65 mm pitch; compatible with standard reflow profiles. |
Pinout & Package
DFN2020-6 (SOT1118) is a 6-terminal, leadless, thermally enhanced ultra-thin plastic package with exposed thermal pad (not electrically connected), optimized for high-density routing and improved power dissipation on FR4 PCBs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter terminal of TR1 (NPN); common reference for first transistor's current path. |
| 2 | I1 | Base input of TR1 (NPN); driven through R1; accepts logic-high signals to activate sink path. |
| 3 | O2 | Collector output of TR2 (PNP); provides sourcing capability when TR2 is active. |
| 4 | GND2 | Emitter terminal of TR2 (PNP); independent ground return for second transistor. |
| 5 | I2 | Base input of TR2 (PNP); driven through R1; activated by logic-low or open-drain pull-down. |
| 6 | O1 | Collector output of TR1 (NPN); provides sinking capability when TR1 is active. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-polarity RET integration | Single-package NPN + PNP pair eliminates discrete pairing errors and layout mismatch in complementary circuits. |
| Pre-biased input network | R1 = 2.2 kΩ and R2 = 10 kΩ reduce BOM count by removing four external resistors per channel. |
| Thermally robust DFN2020-6 | Rth(j-a) = 125 K/W (4-layer PCB, 1 cm² pad) enables 500 mA operation without forced air or heatsink. |
| Low VCE(sat) and fast fT | 100 mV saturation and 210 MHz fT support clean 10–20 MHz digital switching with minimal propagation delay. |
| Wide operating temperature | Rated from −55 °C to +150 °C junction temperature; suitable for industrial and automotive under-hood auxiliary modules. |
Applications
| Logic-Level Translation | Dual-Supply Load Switching |
|---|---|
|
Use Scenario: Interfacing 3.3 V microcontroller outputs to 5 V or 12 V peripheral inputs requiring TTL-compatible thresholds. IC Role / Device Role: TR1 (NPN) sinks current from 5 V line when MCU GPIO is high; TR2 (PNP) pulls up when GPIO is low-enabling bidirectional level shift without external resistors. Use Value: Eliminates need for discrete resistor-divider networks or dedicated level translators, reducing footprint by >40% and component count by 4 parts per channel. |
Use Scenario: Controlling dual-rail loads such as half-bridge gate drivers or dual-voltage sensors where one side requires sourcing and the other sinking. IC Role / Device Role: TR1 switches ground path (low-side) while TR2 switches VCC path (high-side), both driven from shared control signal with inverted logic polarity. Use Value: Enables true complementary switching in <1.5 mm² area-critical for motor driver pre-driver stages and isolated I/O modules. |
| GPIO Expansion Interface | Cost-Optimized Signal Inversion |
|
Use Scenario: Expanding limited MCU GPIO count to drive multiple LED indicators, optocoupler inputs, or small solenoids in consumer IoT hubs. IC Role / Device Role: Each transistor acts as independent switch: TR1 drives cathode-connected LEDs; TR2 drives anode-connected loads-both share same control net via logic inversion. Use Value: Delivers two fully functional, resistor-biased switches per 2 mm × 2 mm footprint-replacing two BC846/BC856 pairs and eight resistors. |
Use Scenario: Generating inverted logic copies for clock enable, reset distribution, or status feedback in battery-powered sensor nodes. IC Role / Device Role: TR1 inverts active-high signal; TR2 inverts active-low signal-providing matched delay and drive strength without skew-sensitive RC networks. Use Value: Achieves sub-10 ns propagation skew between channels with guaranteed VOH/VOL compliance across temperature, unlike passive inverters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-transistor switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN32PA | NPN/NPN configuration only; identical R1/R2 values and package; no PNP section. | Suitable only for dual-sink or parallel-drive topologies-not for complementary or level-shifting use cases. | Select when both channels require sinking behavior and no sourcing capability is needed. |
| BC846B/BC856B pair | Discrete transistors without integrated bias resistors; requires four external 2.2 kΩ/10 kΩ resistors per pair. | Higher assembly cost and larger footprint (≥3× area); susceptible to resistor tolerance stacking and thermal drift. | Choose only if legacy design reuse or extreme cost sensitivity outweighs board space and reliability benefits. |
Compared with PIMN32PA, the PIMC32PA adds PNP functionality enabling true complementary operation; versus discrete BC846/BC856, it reduces layout area by 65%, eliminates 4 passives per channel, and guarantees matched R1/R2 tracking across temperature and voltage.

FAQ
What is the maximum continuous current per transistor in PIMC32PA?
The PIMC32PA supports 500 mA continuous output current per transistor under specified thermal conditions (Tamb ≤ 25 °C, 4-layer PCB with 1 cm² copper pad). Derating applies above 25 °C ambient: power dissipation drops linearly to zero at 150 °C junction temperature, per Figure 1 in the datasheet.
Can PIMC32PA be used in analog amplifier configurations?
No-PIMC32PA is not characterized or specified for linear amplification. Its built-in resistors fix base biasing for saturated switching only; hFE and VCE(sat) are specified under switching conditions (IC/IB = 20), and no small-signal parameters like gm or noise figure are provided in the datasheet.
How does the pinout support PCB layout efficiency?
The DFN2020-6 pinout places GND1 (Pin 1) and GND2 (Pin 4) on opposite corners, allowing separate ground returns for each transistor to minimize crosstalk. O1 (Pin 6) and O2 (Pin 3) are positioned diagonally to simplify routing of complementary load paths without layer jumps or vias in dense layouts.
Is PIMC32PA automotive-qualified?
No-PIMC32PA is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 15 and confirms no AEC-Q101 stress testing or automotive-specific screening has been performed. It is intended for industrial, consumer, and computing applications only.
