Product details
Overview
PEMD14 from Nexperia is a dual NPN/PNP resistor-equipped transistor (RET) in SOT666 package, integrating one 47 kΩ input bias resistor per transistor with R2 open, rated for 50 V VCEO and 100 mA output current per channel. It functions as a compact, pre-biased switching pair for digital logic interfacing and low-current peripheral control in space-constrained PCBs.
For engineers reviewing the PEMD14 datasheet, PEMD14 pinout, PEMD14 application, or PEMD14 equivalent, this device is selected for its integrated biasing, reduced external component count, and verified performance in IC input control and discrete transistor replacement within 5 V–30 V digital systems.
Technical Context
The PEMD14 integrates two complementary transistors-TR1 (NPN) and TR2 (PNP)-each with a dedicated 47 kΩ input bias resistor (R1), while R2 is unconnected. Its dual-channel configuration enables push-pull or complementary switching without external base resistors.
Each transistor operates under independent biasing: TR1 supports VCE up to 50 V and IO up to 100 mA with hFE ≥100 at IC = 1 mA; TR2 delivers matching PNP capability with VEBO = 5 V and VI(on) = 2.5 V typical, enabling direct TTL/CMOS-level drive compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage for both NPN and PNP transistors under open-base conditions. |
| IO | 100 mA - Continuous DC output current rating per transistor, defining maximum load drive capability. |
| R1 | 47 kΩ (typical) - Integrated base bias resistor value, eliminating need for external pull-up/down components. |
| hFE | ≥100 - Minimum DC current gain at VCE = 5 V, IC = 1 mA, ensuring reliable saturation with low base drive. |
| VCE(sat) | ≤150 mV - Max collector-emitter saturation voltage at IC = 10 mA, IB = 0.5 mA, minimizing conduction loss. |
| fT | 230 MHz (TR1), 180 MHz (TR2) - Transition frequency confirming suitability for high-speed digital switching up to ~50 MHz. |
Pinout & Package
SOT666 ultra-small flat-lead surface-mount package: 6-pin, 0.5 mm pitch, 1.6 mm × 1.2 mm × 0.55 mm body height. Designed for reflow soldering only on FR4 PCBs with standard footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1 (NPN); common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1 (NPN); internally connected to 47 kΩ resistor R1 to GND1. |
| 3 | O2 | Collector output for TR2 (PNP); active-high switching node when TR2 is enabled. |
| 4 | GND2 | Emitter connection for TR2 (PNP); independent ground reference for second transistor channel. |
| 5 | I2 | Base input for TR2 (PNP); internally connected to 47 kΩ resistor R1 to GND2. |
| 6 | O1 | Collector output for TR1 (NPN); active-low switching node when TR1 is enabled. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | 47 kΩ R1 per transistor eliminates need for two external base resistors, reducing BOM count by ≥2 parts. |
| Dual complementary topology | NPN/PNP pairing enables single-package push-pull or level-shifting without cross-coupling or layout mismatch. |
| Ultra-compact SOT666 footprint | 1.6 mm × 1.2 mm area saves >60% board space vs. two discrete SOT23 transistors with external resistors. |
| Verified thermal performance | 416 K/W junction-to-ambient (per device) ensures stable operation up to 125 °C ambient with no derating below 200 mW. |
Applications
| Low-Current Peripheral Driver | IC Input Control |
|---|---|
|
Use Scenario: Driving LED indicators, small solenoids, or optocoupler inputs in microcontroller-based systems with limited GPIO drive strength. IC Role / Device Role: Dual-channel switch providing active-low (TR1) and active-high (TR2) outputs from shared logic-level inputs. Use Value: Eliminates need for separate NPN and PNP drivers and their associated base resistors, cutting PCB area and assembly cost. |
Use Scenario: Conditioning signals between mixed-voltage ICs (e.g., 3.3 V MCU controlling 5 V logic inputs). IC Role / Device Role: Level translator and current amplifier, converting weak logic outputs into robust, rail-to-rail compatible inputs. Use Value: Built-in 47 kΩ biasing ensures correct turn-on thresholds across temperature, avoiding marginal switching behavior. |
| General-Purpose Transistor Replacement | Compact Logic Interface |
|
Use Scenario: Upgrading legacy designs using discrete BC847/BC857 pairs where space or assembly yield is constrained. IC Role / Device Role: Drop-in functional replacement with identical electrical behavior but integrated bias network. Use Value: Maintains existing signal timing and voltage thresholds while reducing placement errors and solder joint count. |
Use Scenario: Implementing enable/disable control for multiple subsystems (e.g., sensors, regulators) from a single microcontroller port. IC Role / Device Role: Dual independent switch enabling concurrent activation of complementary loads (e.g., power ON/OFF sequencing). Use Value: Pin 2 (I1) and Pin 5 (I2) accept independent logic inputs, allowing asynchronous control of O1 and O2 outputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMB14 | PNP/PNP dual RET (no NPN channel); same SOT666 package and 47 kΩ R1. | Used where two high-side switches are required instead of complementary switching. | Select when circuit requires dual sourcing rather than push-pull or bidirectional control. |
| PEMH14 | NPN/NPN dual RET; identical package, R1 = 47 kΩ, but no PNP channel. | Suitable for parallel load driving or dual-sinking configurations, not level translation. | Choose for redundant low-side switching or when both outputs must sink current simultaneously. |
Compared with PEMB14 and PEMH14, the PEMD14 uniquely provides matched NPN/PNP characteristics in one package-enabling true complementary operation, rail-to-rail signal conditioning, and simplified interface design where both sourcing and sinking capability is required per control line.

FAQ
What is the function of R2 being 'open' in the PEMD14?
R2 is unconnected (open) in the PEMD14, meaning only R1 (47 kΩ) is integrated per transistor channel. This configuration provides fixed-base biasing without feedback or divider networks, simplifying drive requirements and ensuring predictable turn-on behavior with standard logic levels.
Can PEMD14 be used in analog amplification applications?
No-the PEMD14 is characterized and specified exclusively for switching operation. Its hFE variation, saturation voltage, and built-in resistor values are optimized for digital on/off control, not linear gain stability or low-noise analog signal amplification.
Is the SOT666 package lead-free and RoHS compliant?
Yes-Nexperia confirms the PEMD14 SOT666 package meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound, compliant with JEDEC J-STD-020 moisture sensitivity level 1.
How does thermal derating apply to the PEMD14 at elevated ambient temperatures?
Per device total power dissipation is rated at 300 mW at Tamb ≤ 25 °C, derating linearly to zero at 150 °C. The per-transistor derating curve shows usable power down to 100 mW at 125 °C ambient, validated on FR4 PCB with single-sided 35 µm copper.
