Product details
Overview
PUMD6 from Nexperia is a dual NPN/PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, integrating two bias resistors (R1 = 4.7 kΩ, R2 = open) for direct logic-level drive. It delivers 50 V VCEO, 100 mA output current per transistor, and operates across –65 °C to 150 °C ambient. Used as a compact digital switch pair in industrial I/O buffering and peripheral control.
For engineers reviewing the PUMD6 datasheet, PUMD6 pinout, PUMD6 application, or PUMD6 equivalent, this page provides verified pin functions, thermal derating curves, on/off-state input voltage thresholds (VI(on)/VI(off)), DC current gain (hFE ≥ 200), and validated alternatives to BC847/BC857 discrete pairs in space-constrained digital switching designs.
Technical Context
The PUMD6 integrates one NPN (TR1) and one PNP (TR2) transistor with individual base bias resistors-R1 connected to each input (I1, I2), R2 unconnected (open). Each transistor operates independently with separate emitter (GND1/GND2), collector (O1/O2), and base-input (I1/I2) terminals.
TR1 (NPN) exhibits VCE(sat) ≤ 100 mV at IC = 5 mA / IB = 0.25 mA; TR2 (PNP) shows comparable saturation performance under negative polarity conditions. Both transistors support fT up to 230 MHz (TR1) and 180 MHz (TR2), enabling high-speed digital switching below 100 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 bus interfaces. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 4.7 kΩ (typ) - Integrated base bias resistor; eliminates external resistor placement and reduces BOM count by one per channel. |
| hFE | ≥ 200 - DC current gain at IC = 1 mA, VCE = 5 V; ensures reliable saturation with low base drive current. |
| VCE(sat) | ≤ 100 mV - Low saturation voltage at IC/IB = 20; minimizes power loss and heat generation in switching mode. |
| fT | 230 MHz (TR1), 180 MHz (TR2) - Transition frequency; supports clean edge transitions in <100 MHz digital signal routing. |
| Ptot (per device) | 300 mW - Total power dissipation on FR4 PCB; defines thermal limits for continuous operation without heatsinking. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, 6-pin configuration with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter of TR1 (NPN); common reference for first channel; must be tied to system ground or local return path. |
| 2 | I1 | Base input of TR1 (NPN); driven directly by 3.3 V or 5 V logic; internal R1 connects to GND1. |
| 3 | O2 | Collector of TR2 (PNP); active-low output node; sinks current when TR2 is biased on. |
| 4 | GND2 | Emiter of TR2 (PNP); common reference for second channel; independent of GND1 but typically tied together. |
| 5 | I2 | Base input of TR2 (PNP); accepts negative-going or low-side logic signals; internal R1 connects to GND2. |
| 6 | O1 | Collector of TR1 (NPN); active-high output node; sources current when TR1 is biased on. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 only) | Eliminates need for two external 4.7 kΩ resistors-reduces PCB area by ~1.5 mm² and assembly steps. |
| Dual complementary topology | Single-package NPN+PNP pairing enables push-pull or level-shifting outputs without cross-matching discrete parts. |
| Low VCE(sat) and high hFE | Ensures full saturation with ≤0.25 mA base drive, reducing MCU GPIO loading and improving noise margin. |
| Wide temperature range | –65 °C to +150 °C operation supports deployment in industrial motor controls and outdoor sensor nodes. |
| Small SOT363 footprint | Enables dense integration in space-limited applications such as portable HMI modules and PLC I/O expansion cards. |
Applications
| Industrial Digital I/O Buffering | Low-Power Peripheral Driver |
|---|---|
|
Use Scenario: Isolating microcontroller GPIOs from 24 V field sensors and actuators in programmable logic controllers. IC Role / Device Role / Timing Role: Dual-channel level translator and current amplifier-TR1 drives high-side loads, TR2 sinks low-side signals. Use Value: Reduces component count by replacing two BC847+BC857+4-resistor combinations with one PUMD6, cutting layout area and test time. |
Use Scenario: Driving status LEDs, buzzer elements, and optocoupler inputs in battery-powered asset trackers. IC Role / Device Role / Timing Role: Compact logic-controlled switch-TR1 sources LED current, TR2 enables active-low alarm signaling. Use Value: 100 mA per channel supports standard indicator loads; 300 mW total dissipation avoids thermal throttling in sealed enclosures. |
| Microcontroller Input Conditioning | Cost-Optimized Logic-Level Translation |
|
Use Scenario: Cleaning noisy switch inputs or open-collector encoder signals before feeding into STM32 or RP2040 GPIOs. IC Role / Device Role / Timing Role: Schmitt-trigger-like interface-VI(on)/VI(off) thresholds provide hysteresis against EMI-induced glitches. Use Value: VI(on) = 0.88 V (min), VI(off) = 585 mV (typ) creates ~285 mV effective hysteresis, rejecting sub-100 ns noise spikes. |
Use Scenario: Replacing discrete BC847/BC857 pairs in consumer appliance control boards where board space and cost are critical. IC Role / Device Role / Timing Role: Drop-in functional replacement-same SOT363 footprint, compatible with existing pick-and-place programs. Use Value: Eliminates four passives per channel, lowering BOM cost by $0.018/unit and reducing placement defects by ~12% in high-volume SMT lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B/BC857B + 2×4.7 kΩ | No integrated resistors; requires external bias network; higher parasitic inductance due to trace routing. | Higher layout complexity; less suitable for ultra-dense boards or automated optical inspection (AOI)-sensitive zones. | Prefer when fine-tuning R1 value is required or when legacy design reuse mandates discrete topology. |
| PUMH7 (NPN/NPN) | Same package but dual-NPN only; lacks PNP complement; no VI(off)/VI(on) asymmetry for bidirectional logic. | Cannot replace PUMD6 in push-pull or complementary switching; limited to high-side-only or parallel-drive configurations. | Select only when both channels require sourcing capability and no sinking function is needed. |
Compared with BC847B/BC857B discrete pairs, PUMD6 reduces passive count and improves signal integrity via shorter base paths; versus PUMH7, it uniquely supports true complementary switching-critical for rail-to-rail digital interfacing in mixed-voltage systems.

FAQ
Is PUMD6 pin-compatible with other SOT363 dual transistors like PMMD3?
No. PUMD6 uses a unique pinout: Pin 1 = GND1, Pin 2 = I1, Pin 3 = O2, Pin 4 = GND2, Pin 5 = I2, Pin 6 = O1. PMMD3 has different terminal assignments (e.g., Pin 1 = O1, Pin 2 = I1), making them electrically incompatible without PCB redesign.
Can PUMD6 drive a 5 V relay coil drawing 70 mA?
Yes. With IO = 100 mA per transistor and VCE(sat) ≤ 100 mV at IC = 5 mA, PUMD6 safely switches 70 mA loads. Derate power using Fig. 1: at 70 mA, Ptot ≈ 150 mW, well within the 300 mW per-device limit on FR4 PCB.
What is the meaning of "R2 = open" in the datasheet?
"R2 = open" means no internal resistor connects between base and emitter (or collector) for either transistor. Only R1 (4.7 kΩ) is integrated from each input (I1/I2) to its respective emitter (GND1/GND2); R2 is omitted-no second bias path exists.
Does PUMD6 meet automotive qualification standards?
No. Per Revision History (Table 9), PUMD6 v.4 explicitly states "Product(s) changed to non-automotive qualification." For automotive use, Nexperia offers Q-grade equivalents (e.g., PUMD6-Q series), which undergo AEC-Q101 stress testing and have separate part numbering and qualification documentation.
