Product details
Overview
PUMD3 from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated bias resistors R1 = R2 = 10 kΩ. It functions as a dual-channel digital switch for level translation and load control in compact automotive and industrial PCBs.
For engineers reviewing the PUMD3 datasheet, PUMD3 pinout, PUMD3 application, or PUMD3 equivalent, this device serves as a space- and BOM-optimized replacement for discrete BC847/BC857 pairs in low-voltage digital interface circuits requiring matched NPN+PNP switching with built-in base biasing.
Technical Context
The PUMD3 integrates two complementary bipolar transistors - TR1 (NPN) and TR2 (PNP) - each with dedicated on-chip bias resistors (R1 = 10 kΩ, R2 = 10 kΩ, ratio = 1.0). Its dual-transistor topology enables push-pull or complementary switching without external base resistors.
It operates within ±10 V input voltage range per channel, supports 50 V collector-emitter breakdown, and delivers 100 mA continuous output current per transistor. Thermal resistance is 417 K/W (per device, FR4 PCB), enabling stable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; defines rail compatibility with 3.3 V/5 V/12 V logic and power domains. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs without external current amplification. |
| R1 / R2 | 10 kΩ / 10 kΩ - Matched on-die base bias resistors eliminate need for external components and ensure consistent turn-on behavior across temperature. |
| hFE (TR1) | 30 min - DC current gain of NPN transistor at VCE = 5 V, IC = 5 mA; ensures reliable saturation with ≤0.5 mA base drive. |
| VCE(sat) | 100 mV max - Low saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes power loss and heating in switching applications. |
| fT (TR1/TR2) | 230 MHz / 180 MHz - Transition frequency confirms suitability for digital switching up to ~10–20 MHz edge rates, not RF amplification. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, optimized for high-density routing and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by logic-level signal with internal R1 biasing. |
| 3 | O2 | Collector output for TR2 (PNP); active-low switching node referenced to VCC. |
| 4 | GND2 | Emiter connection for TR2 (PNP); common reference for second transistor channel, isolated from GND1. |
| 5 | I2 | Base input for TR2 (PNP); accepts negative-going or low-side logic signals with internal R1 biasing. |
| 6 | O1 | Collector output for TR1 (NPN); active-high switching node referenced to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary RET topology | Single-package integration of matched NPN+PNP transistors eliminates layout mismatch and reduces board area by >40% vs. discrete pair. |
| Built-in 10 kΩ bias resistors | Removes four external resistors per channel, cutting BOM count, placement cost, and potential solder joint failure points. |
| 100 mA per transistor rating | Supports direct driving of medium-current loads (e.g., optocoupler LEDs, small solenoids) without additional driver stages. |
| Low VCE(sat) (≤100 mV) | Reduces conduction loss to <1 mW at 10 mA, enabling thermally efficient operation in sealed or high-ambient environments. |
| SC-88 (SOT363-3) package | Enables 0.65 mm pitch routing on 2-layer PCBs and compatibility with standard TSSOP reflow profiles (J-STD-020). |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Level-shifting 3.3 V microcontroller GPIO to drive 12 V lamp control lines in door module PCBs. IC Role / Device Role / Timing Role: Dual-channel switch translating logic states while providing galvanic separation between MCU and load side. Use Value: Eliminates need for separate NPN+PNP drivers and four bias resistors, reducing component count by six parts per channel. |
Use Scenario: Converting 24 V sinking/sourcing field inputs into clean 3.3 V CMOS-compatible signals for ARM-based controller inputs. IC Role / Device Role / Timing Role: Bidirectional interface buffer with configurable polarity via independent NPN/PNP channels. Use Value: Enables single-component solution for both high- and low-side input conditioning, cutting layout complexity and test time. |

|
Use Scenario: Driving multiple LED status indicators and buzzer elements from a battery-powered SoC with limited GPIO drive strength. IC Role / Device Role / Timing Role: Current-boosting digital output stage with integrated biasing for consistent brightness and audible tone generation. Use Value: Delivers 100 mA per LED/buzzer without external transistors, extending battery life via low VCE(sat) and minimal quiescent current. |
Use Scenario: Controlling power-up sequence of auxiliary rails (e.g., 5 V → 3.3 V → 1.8 V) using microcontroller GPIO with open-drain emulation. IC Role / Device Role / Timing Role: Programmable enable switch with fast turn-on (<100 ns propagation delay implied by fT) and precise timing margin. Use Value: Ensures deterministic power sequencing without RC delays or extra timing ICs, improving system reliability during cold start. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH11 | NPN/NPN configuration; identical R1/R2 values and SOT363-3 package. | Used where dual-sourcing or parallel switching is required instead of complementary control. | Select when both outputs must sink current (e.g., driving common-anode displays or dual low-side switches). |
| PUMB11 | PNP/PNP configuration; same bias resistor values and thermal specs as PUMD3. | Preferred for high-side switching stacks or inverted logic interfaces requiring dual sourcing capability. | Choose for applications needing two active-high outputs referenced to VCC, such as bus termination or pull-up networks. |
Compared with PUMD3, PUMH11 offers dual-NPN functionality ideal for sinking-heavy loads, while PUMB11 provides dual-PNP sourcing for high-side control - neither matches the complementary NPN/PNP pairing essential for push-pull or bidirectional interface roles.

FAQ
What is the maximum operating temperature for PUMD3?
The PUMD3 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. When mounted on a standard FR4 PCB with single-sided 35 µm copper, its thermal resistance is 417 K/W per device, allowing full 100 mA operation up to +85 °C ambient with proper layout.
Can PUMD3 replace BC847 and BC857 transistors directly?
Yes - PUMD3 serves as a functional drop-in replacement for BC847 (NPN) + BC857 (PNP) pairs in digital switching applications. Its integrated 10 kΩ bias resistors eliminate four external components, and its SOT363-3 footprint aligns with common dual-transistor land patterns, though pin mapping differs and requires schematic update.
Does PUMD3 support 5 V logic interfacing without level shifters?
Yes - the PUMD3's VI(on) is 1.8–2.5 V (TR1) and −1.8 to −2.5 V (TR2), and VI(off) is ±0.8–1.1 V, making it fully compatible with standard 5 V TTL and CMOS logic families. No external level-shifting circuitry is needed for direct GPIO connection.
How does the R2/R1 ratio affect switching performance?
The R2/R1 ratio of 0.8–1.2 (typ. 1.0) ensures matched base current division between input and feedback paths, stabilizing DC bias point and minimizing variation in VCE(sat) and switching thresholds across temperature and process corners - critical for consistent digital behavior in production units.
