Product details
Overview
PIMC31PA from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in a DFN2020-6 (SOT1118) package, rated for 50 V VCEO and 500 mA output current per transistor, with integrated bias resistors R1 = 1 kΩ and R2/R1 = 10, used for digital switching and IC input control in space-constrained PCBs.
For engineers reviewing the PIMC31PA datasheet, PIMC31PA pinout, PIMC31PA application, or PIMC31PA equivalent, this device serves as a compact, resistor-integrated alternative to discrete BC807/BC817 pairs in level-shifting, load switching, and logic interface circuits where board area and assembly cost are critical.
Technical Context
The PIMC31PA integrates two complementary transistors - TR1 (NPN) and TR2 (PNP) - each with monolithically embedded base bias resistors (R1 = 1 kΩ, R2 = 10 kΩ), enabling direct logic-level drive without external bias networks. It operates across −55 °C to 150 °C ambient temperature with 50 V breakdown ratings on both VCBO and VCEO.
Each transistor delivers hFE ≥ 70 at IC = 50 mA and VCE = 5 V (TR1) or −5 V (TR2), with VCE(sat) ≤ 100 mV at IC = 50 mA / IB = 2.5 mA (TR1) and ≤ −100 mV under symmetric PNP conditions, supporting efficient low-voltage switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - supports rail-to-rail switching up to 48 V logic or supply domains. |
| IO | 500 mA per transistor - enables direct driving of moderate-current loads like LEDs, relays, or gate inputs. |
| R1 | 1 kΩ ±30% - sets base current for predictable turn-on with standard 3.3 V/5 V logic outputs. |
| R2/R1 ratio | 10 ±10% - ensures stable bias network gain for consistent saturation and noise immunity. |
| hFE | ≥70 at 50 mA - guarantees reliable current amplification without marginal conduction in digital switch mode. |
| VCE(sat) | ≤100 mV (NPN), ≤−100 mV (PNP) - minimizes power loss and voltage drop in high-duty-cycle switching. |
| fT | 210 MHz (NPN), 150 MHz (PNP) - supports fast edge rates in signal routing and pulse-width modulation. |
Pinout & Package
DFN2020-6 (SOT1118) leadless plastic package: 2 mm × 2 mm × 0.65 mm body, 0.65 mm pitch, thermal-enhanced ultra-thin outline optimized for high-density routing and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 (emitter TR1) | NPN emitter reference - connects to system ground or low-side return path for TR1. |
| 2 | I1 (base TR1) | NPN input - accepts logic-high signal directly; internal R1 limits base current. |
| 3 | O2 (collector TR2) | PNP collector output - sinks current when TR2 is active; used for high-side or inverted switching. |
| 4 | GND2 (emitter TR2) | PNP emitter reference - ties to positive rail or high-side common for TR2 operation. |
| 5 | I2 (base TR2) | PNP input - driven low to activate TR2; internal R1–R2 network provides pull-up bias. |
| 6 | O1 (collector TR1) | NPN collector output - sources current when TR1 is active; standard low-side switch node. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates 4 external resistors per pair, reducing BOM count and layout area by >60% vs. discrete BC807+BC817. |
| 500 mA per transistor rating | Supports direct drive of 20 mA LED strings (25×), small solenoids, or microcontroller I/O expansion without buffer stages. |
| DFN2020-6 thermal performance | 125 K/W Rth(j-a) on 4-layer FR4 - enables 700 mW total dissipation at 25 °C ambient, suitable for continuous 300 mA switching. |
| Complementary NPN/PNP topology | Enables push-pull, level-shifting, and bidirectional signal control in single-package footprint - no matching or pairing required. |
| −55 °C to 150 °C operating range | Validated for industrial automation, automotive body electronics (non-safety), and outdoor IoT nodes without derating. |
Applications
| LED Driver Interface | Microcontroller I/O Expander |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN31PA | NPN/NPN configuration only - lacks PNP complement for push-pull or high-side sinking. | Suitable only for dual low-side switching; cannot replace PIMC31PA in level-shifting or bidirectional interfaces. | Select when two independent NPN switches are needed and polarity inversion is unnecessary. |
| PIMP31PA | PNP/PNP configuration only - no NPN section for standard low-side drive or logic-compatible inputs. | Limited to dual high-side or inverted-output applications; incompatible with direct MCU GPIO sourcing. | Choose only for dual high-side load control where both outputs must sink current relative to VCC. |
Compared with PIMN31PA and PIMP31PA, the PIMC31PA uniquely combines complementary NPN/PNP functionality in one die, enabling true push-pull, level translation, and bidirectional signal conditioning without inter-device timing skew or layout mismatch.

FAQ
What is the maximum continuous current per transistor in the PIMC31PA?
The PIMC31PA supports 500 mA continuous output current per transistor under specified thermal conditions (Tamb ≤ 25 °C, 4-layer FR4 PCB). Derating applies above 25 °C ambient, with full 500 mA maintained up to 75 °C using the 1 cm² collector pad layout per Table 5.
Can PIMC31PA replace BC807 and BC817 transistors in existing designs?
Yes - the PIMC31PA is explicitly positioned as a cost-saving alternative to BC807/BC817 pairs in digital applications. Its integrated R1/R2 network replicates typical bias configurations, and its pinout allows direct substitution in new layouts, though PCB footprint differs (DFN2020-6 vs. SOT23).
How does the internal resistor ratio affect switching behavior?
The R2/R1 = 10 ±10% ratio ensures stable base bias division, maintaining consistent VI(on) (0.4–1.4 V) and VI(off) (0.3–1 V) across temperature. This prevents unintended turn-on during logic transitions and improves noise margin in noisy industrial environments.
Is thermal pad connection required for reliable operation?
No thermal pad is present - the DFN2020-6 (SOT1118) package relies on copper pour under terminals 3 and 6 (O2 and O1) for heat dissipation. For 700 mW total power handling, a 1 cm² mounting pad on inner layers is recommended per Table 5 condition [5].
