Product details
Overview
PIMP32X from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT457 (SC-74) package, rated for −50 V VCEO, −500 mA output current per transistor, with integrated R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors; used as compact dual-level logic interface or load switch in space-constrained digital control circuits.
For engineers reviewing the PIMP32X datasheet, PIMP32X pinout, PIMP32X application, or PIMP32X equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, confirmed thermal derating behavior on FR4 PCB, and direct alternatives for RET-based BOM optimization in industrial I/O and microcontroller interfacing.
Technical Context
The PIMP32X integrates two matched PNP transistors with monolithically embedded base bias networks-R1 connects input to base, R2 shunts base to emitter-enabling single-resistor drive without external components. Each transistor operates independently with open-base VCEO = −50 V and IO = −500 mA rating.
Its SC-74 (SOT457) 6-pin layout supports dual-channel switching with shared ground terminals (Pins 1 & 4), separate inputs (Pins 2 & 5), and cross-coupled outputs (Pins 6 & 3). Thermal resistance Rth(j-a) is 298 K/W per device on standard FR4 PCB, enabling sustained operation up to +125 °C ambient with proper layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V per transistor: supports rail-to-rail negative-side switching up to 50 V supply referenced to ground. |
| IO | −500 mA per transistor: drives medium-current loads such as relays, LEDs, or gate inputs without external amplification. |
| R1 | 2.2 kΩ ±30%: sets base current for predictable turn-on at TTL/CMOS-compatible input levels (VI(on) ≈ −0.95 V @ IC = −20 mA). |
| R2/R1 ratio | 4.55 typical: ensures deep saturation (VCEsat ≤ −100 mV @ IC = −50 mA, IB = −2.5 mA) and stable cutoff (VI(off) ≤ −0.65 V). |
| Ptot (per device) | 420 mW @ Tamb ≤ 25 °C: enables dual-transistor operation within thermal limits on standard 35 µm copper FR4 board. |
| hFE | 70 min @ VCE = −5 V, IC = −50 mA: guarantees sufficient current gain for reliable saturation under worst-case temperature and process variation. |
| fT | 140 MHz typical: supports high-speed digital switching up to ~10 MHz with minimal propagation delay. |
Pinout & Package
SOT457 (SC-74) surface-mount plastic package: 6-pin, 2.7 mm × 3.1 mm footprint, 1.3 mm height, gull-wing leads, JEDEC-compliant solder land pattern (reflow: 3.45 mm × 1.95 mm; wave: 5.3 mm × 5.05 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1; driven directly by logic signal through internal R1 resistor. |
| 3 | O2 | Collector output for TR2; active-low switching node for second channel load. |
| 4 | GND2 | Emiter connection for TR2; independent ground return for second transistor channel. |
| 5 | I2 | Base input for TR2; isolated logic input with dedicated R1–R2 network. |
| 6 | O1 | Collector output for TR1; primary active-low switching node for first channel load. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two independent, resistor-equipped PNP transistors in one SC-74 package-eliminates four discrete resistors and two transistors in conventional designs. |
| Guaranteed saturation | R2/R1 = 4.55 ensures forced β ≥ 20, delivering VCEsat ≤ −100 mV at −50 mA, critical for low-loss switching in power-sensitive I/O stages. |
| Input voltage compatibility | VI(on) = −0.95 V typical allows direct interface with 3.3 V and 5 V CMOS/TTL outputs without level-shifting or pull-up resistors. |
| Thermal robustness | Rth(j-a) = 298 K/W (per device) on FR4 enables full 500 mA dual-channel operation up to +85 °C ambient with standard PCB layout. |
| ESD tolerance | HBM rating > 2 kV (per JESD22-A114) ensures reliability during automated assembly and field operation in industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP PBSS4041T | Single PNP RET (not dual); R1 = 10 kΩ, R2 = 47 kΩ; VCEO = −40 V; IO = −400 mA | Requires two devices for dual-channel function; lower voltage/current rating limits use in 24 V industrial loads. | Select when only one channel is needed or when higher R1 value improves noise immunity in noisy environments. |
| ROHM UMD2N | Dual NPN RET; VCEO = +50 V; IO = +150 mA; R1 = 2.2 kΩ, R2 = 47 kΩ; SOT-363 package | Inverts logic polarity; lower current rating restricts use to signal-level loads only-not suitable for 500 mA solenoid drive. | Select for low-voltage NPN-sink applications where positive-side switching is required and current demand is ≤150 mA. |
Compared with PBSS4041T and UMD2N, PIMP32X uniquely delivers dual PNP topology with −50 V/−500 mA rating and matched R1/R2 network in a single SC-74 package-making it the only drop-in solution for space-constrained, high-current, negative-rail switching without redesigning layout or logic polarity.

FAQ
What is the maximum safe operating voltage for PIMP32X in continuous DC switching?
The absolute maximum VCEO is −50 V per transistor under open-base conditions. For reliable long-term operation, Nexperia recommends limiting VCE to ≤−40 V at Tamb ≤ 85 °C with adequate PCB copper pour. Derating is required above 25 °C ambient per Figure 1: at +100 °C, max VCE drops to −32 V to maintain junction temperature ≤150 °C.
Can PIMP32X be used in analog linear amplifier configurations?
No-PIMP32X is characterized and qualified exclusively for digital switching applications. Its built-in R1/R2 network fixes base biasing for saturation/cutoff operation; hFE variation (70–200) and lack of small-signal linearity data make it unsuitable for analog amplification. Use BC807-40 or PBSS4140Z for linear PNP amplifiers.
How does thermal performance differ between per-transistor and per-device power ratings?
Ptot = 290 mW applies to a single transistor under free-air conditions; Ptot = 420 mW applies to the entire dual-device package on FR4 PCB. The higher per-device rating reflects thermal coupling between transistors and improved heat spreading-valid only when both channels operate simultaneously with symmetric loading and standard 35 µm copper layout.
Is PIMP32X pin-compatible with the BC807-40 dual-transistor array?
No-BC807-40 is a dual discrete PNP transistor in SOT-363 (SC-70) with no integrated resistors and different pinout (emitter-common configuration). PIMP32X uses SOT457 (SC-74) with independent emitters (Pins 1 & 4) and cross-coupled collectors (Pins 3 & 6), requiring PCB layout revision for replacement.
