Product details
Overview
PEMD30 from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT666 package, rated for 50 V VCEO, 100 mA output current per transistor, with built-in 2.2 kΩ input bias resistor (R1) and open R2 configuration-used for compact dual-polarity switching in space-constrained peripheral driver circuits.
For engineers reviewing the PEMD30 datasheet, PEMD30 pinout, PEMD30 application, or PEMD30 equivalent, this device serves as a verified drop-in alternative to BC847BVN in low-current digital interface control, offering integrated biasing to eliminate external resistors and reduce PCB footprint in dual-signal path designs.
Technical Context
This dual RET integrates one NPN (TR1) and one PNP (TR2) transistor sharing no internal connection between bases or collectors-each channel operates independently with dedicated input (I1/I2), output (O1/O2), and emitter-ground (GND1/GND2) terminals. Bias resistors are connected only to base inputs, with R1 = 2.2 kΩ confirmed and R2 unconnected (open).
The device targets logic-level interfacing where complementary polarity drive is required without discrete bias networks-enabling direct microcontroller GPIO control of both high-side (PNP) and low-side (NPN) loads while maintaining thermal separation (Tj ≤ 150 °C) and FR4-compatible power dissipation (300 mW per device).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage for both transistors under open-base conditions. |
| IO | 100 mA - Continuous DC output current capability per transistor, defining load-driving capacity. |
| R1 | 2.2 kΩ - Integrated base-input bias resistor enabling direct logic-level drive without external components. |
| Ptot (per device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C on standard FR4 PCB, guiding thermal layout. |
| hFE | 30 min - DC current gain at VCE = 5 V, IC = 20 mA, ensuring predictable switching saturation. |
| VCE(sat) | 150 mV max - Low saturation voltage at IC = 10 mA / IB = 0.5 mA, minimizing conduction loss. |
| Cc (TR1/TR2) | 2.5 pF / 3 pF - Collector capacitance at 1 MHz, influencing high-frequency switching response. |
Pinout & Package
SOT666 is a 6-lead ultra-small flat lead surface-mount plastic package (1.6 mm × 1.2 mm × 0.55 mm body, 0.5 mm pitch), optimized for automated placement and reflow soldering on dense PCBs.
| 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); internally connected to 2.2 kΩ resistor R1. |
| 3 | O2 | Collector output for TR2 (PNP); active-high switching node when TR2 is enabled. |
| 4 | GND2 | Emiter connection for TR2 (PNP); independent ground return for second transistor channel. |
| 5 | I2 | Base input for TR2 (PNP); internally connected to 2.2 kΩ resistor R1 (same value, separate path). |
| 6 | O1 | Collector output for TR1 (NPN); active-low switching node when TR1 is enabled. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-polarity integration | Single SOT666 package contains functionally independent NPN and PNP transistors-eliminates pairing mismatch and saves board area. |
| Built-in bias network | 2.2 kΩ R1 resistor per base input enables direct 3.3 V/5 V logic drive without external pull-up/down components. |
| Reduced BOM count | Replaces two discrete transistors + four bias resistors, cutting component count by ≥66% in dual-switch applications. |
| Thermally robust packaging | 416 K/W junction-to-ambient thermal resistance (per device) supports sustained 100 mA operation on standard FR4. |
Applications
| Low-Current Peripheral Driver | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving LED indicators, small relays, or optocoupler inputs in IoT edge nodes with limited PCB space and low power budget. IC Role / Device Role / Timing Role: Dual RET acts as level-shifting switch pair-TR1 sinks current (low-side), TR2 sources current (high-side) from same logic signal. Use Value: Enables bidirectional signal control from a single GPIO pin while maintaining <150 mV saturation loss and <2.5 pF capacitive loading. |
Use Scenario: Extending limited MCU I/O count to manage multiple enable/disable lines for sensors, regulators, or communication peripherals. IC Role / Device Role / Timing Role: Functions as dual-channel digital buffer-accepts TTL/CMOS logic levels and delivers rail-to-rail switched outputs with defined hFE ≥30. Use Value: Reduces need for discrete transistor arrays; simplifies firmware by allowing simultaneous NPN+PNP activation with inverted logic states. |
| Cost-Sensitive Load Switch | IC Input Control Interface |
Use Scenario: Replacing BC847BVN in consumer electronics power sequencing circuits where dual polarity switching is required at sub-$0.05 BOM cost. IC Role / Device Role / Timing Role: Provides matched NPN/PNP switching with identical R1 values-ensures symmetrical turn-on behavior across both channels. Use Value: Achieves 50 V blocking and 100 mA drive within 1.92 mm² footprint, lowering assembly cost via reduced pick-and-place cycles. |
Use Scenario: Conditioning noisy or floating signals before feeding into sensitive analog or digital IC inputs (e.g., ADC reference enable, reset line conditioning). IC Role / Device Role / Timing Role: Acts as noise-immune digital gate-uses built-in bias to ensure clean logic thresholds and suppress false triggering. Use Value: Eliminates external pull resistors while maintaining <100 nA leakage (ICBO), preserving signal integrity in battery-powered systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-polarity resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMH30 | NPN/NPN configuration (not NPN/PNP); identical R1 = 2.2 kΩ, same SOT666 package and ratings. | Suitable only where dual low-side switching is needed-not interchangeable for complementary drive. | Select when driving two grounded loads from separate control lines. |
| PEMB30 | PNP/PNP configuration; same R1 value and package, but no NPN channel. | Applicable only for dual high-side switching; lacks low-side capability of PEMD30. | Choose for redundant high-side control or mirrored sourcing paths. |
Compared with PEMH30 and PEMB30, PEMD30 uniquely provides mixed-polarity switching in one package-enabling single-GPIO complementary drive that neither alternative supports, making it irreplaceable in space-constrained push-pull or level-shifting topologies.

FAQ
What is the function of R2 in PEMD30?
R2 is open (unconnected) in the PEMD30-only R1 (2.2 kΩ) is implemented per transistor base. This configuration allows direct logic-level drive without pull-down requirements, distinguishing it from dual-resistor RET variants like PEMD20 where R2 is populated.
Can PEMD30 replace BC847BVN in existing designs?
Yes-PEMD30 is explicitly cited as a cost-saving alternative to BC847BVN for low-current peripheral drivers. Its integrated R1 eliminates two external resistors, and its SOT666 footprint is compatible with modified land patterns; electrical parameters (VCEO, IO, hFE) meet or exceed BC847BVN specifications.
Is PEMD30 qualified for automotive applications?
No-this device is non-automotive qualified. The datasheet revision history confirms removal of automotive qualification in the 2023 update. It is intended for industrial, computing, and consumer applications only; use in automotive systems requires formal qualification and is not supported by Nexperia.
How does thermal performance differ between per-transistor and per-device ratings?
Per-transistor Ptot is 200 mW; per-device (both transistors combined) is 300 mW. This indicates shared thermal path-simultaneous full-load operation of both transistors must stay within 300 mW total, requiring derating if both channels conduct continuously at >100 mA.
