Product details
Overview
PEMB2 from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT666 package, rated for −50 V VCEO, −100 mA output current per transistor, with integrated 47 kΩ input bias resistors (R1 = R2 = 47 kΩ). It functions as a dual digital switching element for low-current logic interfacing and peripheral control in space-constrained PCBs.
For engineers reviewing the PEMB2 datasheet, PEMB2 pinout, PEMB2 application, or PEMB2 equivalent, this device is selected for compact dual-PNP switching where built-in biasing eliminates discrete resistors, reduces BOM count, and supports fast digital signal translation in industrial I/O and microcontroller interface circuits.
Technical Context
The PEMB2 integrates two matched PNP transistors with monolithically embedded base bias resistors-R1 (input resistor) and R2 (base-emitter feedback resistor)-configured to enable direct TTL/CMOS-level input drive without external components. Each transistor operates independently with open-base VCEO = −50 V and IO = −100 mA rating.
Its SOT666 package provides six leads in 0.5 mm pitch, with GND pins assigned to both emitters (Pin 1 and Pin 4), enabling independent grounding of each transistor's emitter path. The internal resistor ratio R2/R1 = 1.0 ±0.2 ensures consistent saturation behavior across temperature (−40 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage with base open; defines high-side switching headroom in negative-rail applications. |
| IO | −100 mA - Continuous DC output current per transistor; supports driving LEDs, small relays, or logic inputs directly. |
| R1 / R2 | 47 kΩ / 47 kΩ - Integrated base-input and base-emitter resistors; eliminate need for 4 external resistors in dual-transistor switch design. |
| VCE(sat) | −150 mV @ IC = −10 mA, IB = −0.5 mA - Low saturation voltage enables efficient switching with minimal power loss and heat generation. |
| hFE | 80 min @ VCE = −5 V, IC = −5 mA - Minimum DC current gain ensures reliable turn-on under worst-case bias conditions. |
| Ptot (per device) | 300 mW @ Tamb ≤ 25 °C - Total thermal dissipation limit on FR4 PCB; derates linearly above 25 °C per 417 K/W junction-to-ambient resistance. |
Pinout & Package
SOT666 ultra-small flat-lead plastic package: 1.6 mm × 1.2 mm × 0.55 mm body, 6-pin, 0.5 mm pitch, lead-free and RoHS-compliant. Designed for reflow soldering only on standard FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; must be tied to local ground reference for proper biasing and current return path. |
| 2 | I1 | Base input for TR1; accepts logic-level signals (e.g., 0 V or −1.6 V typical ON-state); internally pulled through R1 to GND1. |
| 3 | O2 | Collector output for TR2; active-low switching node; sinks current when TR2 is ON. |
| 4 | GND2 | Emiter connection for TR2; independent ground terminal allows separate current return paths or isolation between channels. |
| 5 | I2 | Base input for TR2; functionally identical to I1; driven by second logic signal with same voltage thresholds. |
| 6 | O1 | Collector output for TR1; active-low switching node; electrically isolated from O2 except via shared PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with matched R1/R2 values simplify dual-channel level-shifting and reduce footprint vs. discrete solutions. |
| Integrated bias network | Eliminates four external resistors per channel, cutting component count, placement time, and potential solder joint failure points. |
| Low VCE(sat) and high hFE | Ensures deep saturation at low drive currents (e.g., −0.5 mA base), minimizing power loss and enabling use with weak MCU outputs. |
| SOT666 thermal performance | 417 K/W junction-to-ambient resistance on FR4 allows 300 mW total dissipation-sufficient for sustained 100 mA switching at ambient ≤ 50 °C. |
Applications
| Industrial I/O Expansion | Microcontroller GPIO Buffering |
|---|---|
|
Use Scenario: Driving optocoupler inputs or LED status indicators from PLC output modules operating at −24 V rail. IC Role / Device Role / Timing Role: Dual active-low switch translating 0 V / −24 V logic levels while providing current gain and isolation. Use Value: Replaces two discrete PNP+resistor pairs, saving >2.5 mm² PCB area and eliminating resistor placement errors in high-volume assembly. |
Use Scenario: Interfacing 3.3 V or 5 V microcontroller GPIOs to −5 V or −12 V analog front-end circuitry requiring inverted enable signals. IC Role / Device Role / Timing Role: Level-shifting and polarity-inverting buffer with sub-microsecond turn-off delay due to low Cc (3 pF). Use Value: Enables direct drive from MCU pins without external pull-up resistors or level translators-reducing BOM cost by $0.018/unit at volume. |
| Low-Power Sensor Interface | Legacy Logic Signal Conditioning |
|
Use Scenario: Enabling/disabling analog sensor bias rails (e.g., −3.3 V reference) based on system sleep/wake state in battery-powered edge nodes. IC Role / Device Role / Timing Role: Low-quiescent-current switch controlling power domain sequencing with <100 nA leakage (ICEO ≤ −1 µA). Use Value: Achieves <1 µA total standby current per channel-critical for multi-year battery life in IoT endpoint designs. |
Use Scenario: Converting legacy −5 V TTL logic outputs to modern 0 V/3.3 V compatible inputs in retrofitted instrumentation systems. IC Role / Device Role / Timing Role: Active-low translator with VI(on) = −1.6 V and VI(off) = −1.2 V, ensuring noise margin against −0.8 V threshold. Use Value: Provides deterministic switching without external hysteresis components-eliminating timing jitter in critical control loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMD12 | NPN/PNP complement; single NPN + single PNP pair; different pinout (SOT666, but I/O assignment differs); R1 = 10 kΩ, R2 = 47 kΩ. | Used where mixed-polarity switching (e.g., push-pull driver stage) is required instead of dual-sink configuration. | Select PEMD12 only when complementary output polarity (one sourcing, one sinking) is needed-PEMB2 is not pin-compatible. |
| PEMH2 | NPN/NPN version; same SOT666 package; R1 = R2 = 47 kΩ; VCEO = +50 V, IO = +100 mA. | Required for positive-rail switching (e.g., 5 V or 12 V logic domains), not negative-rail applications like PEMB2. | Choose PEMH2 for +VCC referenced loads; PEMB2 remains optimal for −VEE/ground-referenced sink drivers. |
Compared with PEMD12 and PEMH2, PEMB2 uniquely delivers matched dual-PNP functionality with symmetrical −50 V ratings and identical biasing-making it the sole choice for compact, high-reliability negative-rail digital switching where channel matching and layout symmetry matter.

FAQ
What is the maximum allowable continuous current per channel?
The PEMB2 supports −100 mA DC output current per transistor under Tamb ≤ 25 °C with proper PCB copper area. Derating applies above 25 °C: power dissipation drops linearly at 2.4 mW/°C beyond 25 °C, based on 417 K/W thermal resistance. At 70 °C ambient, max usable current is ~75 mA per channel to stay within 300 mW total device limit.
Can PEMB2 be used in automotive applications?
No. The PEMB2 is explicitly marked as non-automotive qualified in its revision history and legal disclaimers. It has not undergone AEC-Q101 stress testing or qualification for automotive temperature ranges (−40 °C to +125 °C junction), nor does it meet automotive PPAP or reliability requirements. Use only in industrial, consumer, or commercial environments.
How does the built-in R2 resistor affect switching behavior?
R2 provides base-emitter feedback that stabilizes the transistor in saturation and improves turn-off speed by actively discharging the base charge. With R2 = 47 kΩ and R1 = 47 kΩ, the R2/R1 ratio of 1.0 ensures predictable VI(on) (−1.6 V typ.) and VI(off) (−1.2 V typ.), giving ≥0.4 V noise margin-critical for robust operation in noisy industrial settings.
Is there a recommended PCB footprint for SOT666?
Yes. Nexperia specifies a reflow-optimized footprint with 0.55 mm pad length, 0.3 mm pad width, 0.6 mm spacing between inner pads, and 2.75 mm × 2.45 mm overall land pattern. Thermal relief is advised for GND pads (Pins 1 and 4) to ensure even solder melting during reflow. Full dimensions and stencil recommendations are in Figure 11 of the official datasheet.
