Product details
Overview
PEMH2 from Nexperia is an NPN/NPN 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 in compact logic interface and peripheral driver circuits.
For engineers reviewing the PEMH2 datasheet, PEMH2 pinout, PEMH2 application, or PEMH2 equivalent, this device is selected for space-constrained digital signal conditioning where reduced BOM count, simplified base drive, and matched dual-transistor behavior are required - especially in low-voltage I/O buffering and microcontroller GPIO expansion.
Technical Context
The PEMH2 integrates two identical NPN transistors, each with on-chip base-emitter bias network (R1 = 47 kΩ, R2 = 47 kΩ), enabling direct TTL/CMOS-level input drive without external resistors. Its R2/R1 ratio of 1.0 ensures consistent saturation behavior across temperature.
Designed for surface-mount operation on FR4 PCBs, it delivers 200 mW per transistor (300 mW per device) at Tamb = 25 °C, with thermal resistance Rth(j-a) = 625 K/W per transistor and 417 K/W per device under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with open base; defines rail compatibility up to 5 V logic with margin. |
| IO | 100 mA - Continuous DC output current per transistor; supports driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 47 kΩ / 47 kΩ - Integrated base bias resistors eliminate need for external pull-up/pull-down; enables direct MCU GPIO connection. |
| hFE | 80 min - DC current gain at VCE = 5 V, IC = 5 mA; ensures reliable saturation with ≤0.5 mA base drive. |
| VCE(sat) | 150 mV max - Low saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes power loss in switching mode. |
| fT | 230 MHz typ - Transition frequency at VCE = 5 V, IC = 10 mA; supports fast digital switching up to ~10–20 MHz. |
Pinout & Package
SOT666 plastic surface-mount package: 6-lead, 0.5 mm pitch, 1.6 mm × 1.2 mm × 0.55 mm body height. Ultra-flat profile suitable for high-density PCB layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for transistor TR1; common reference node for first channel. |
| 2 | I1 | Base input for TR1; internally connected to R1 (47 kΩ) and R2 (47 kΩ) network. |
| 3 | O2 | Collector output for TR2; active-high switching node for second channel. |
| 4 | GND2 | Emiter connection for transistor TR2; independent reference for second channel. |
| 5 | I2 | Base input for TR2; identical internal bias network as I1. |
| 6 | O1 | Collector output for TR1; primary switching node for first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two matched, resistor-equipped transistors in one ultra-small SOT666 package - reduces footprint by >40% vs discrete equivalents. |
| Integrated bias network | R1 = R2 = 47 kΩ with ±22 kΩ tolerance (33–61 kΩ); eliminates 4 external resistors per pair and associated layout area. |
| Low VCE(sat) and high hFE | 150 mV max saturation voltage and ≥80 DC gain ensure robust turn-on with minimal base current - ideal for 3.3 V/5 V MCU outputs. |
| Thermal performance | 417 K/W per-device Rth(j-a) on FR4 PCB enables sustained 100 mA operation without heatsinking in ambient ≤75 °C. |
Applications
| Microcontroller GPIO Expander | LED Driver Interface |
|---|---|
Use Scenario: Driving multiple low-current loads (e.g., status LEDs, optocoupler inputs) from limited GPIO pins on an ARM Cortex-M0+ MCU. IC Role / Device Role / Timing Role: Dual-channel level-shifting switch translating 3.3 V logic to 5 V LED anode control with current limiting via VCE(sat). Use Value: Eliminates 4 discrete resistors and 2 transistors per channel, reducing BOM cost by $0.018/unit and saving 2.2 mm² PCB area. |
Use Scenario: Controlling bi-color LED indicators in industrial HMI panels where space and component count are constrained. IC Role / Device Role / Timing Role: Dual NPN sink driver enabling independent on/off control of red/green segments using common-anode configuration. Use Value: Matched hFE and VCE(sat) ensure uniform brightness; integrated R1/R2 prevent ghosting during rapid state transitions. |
| Digital Logic Level Translator | Peripheral Enable Switch |
Use Scenario: Interfacing 1.8 V FPGA I/O banks to 5 V legacy peripherals requiring clean enable/disable signaling. IC Role / Device Role / Timing Role: Voltage-tolerant input stage (VI(on) = 1.6–3.0 V) driving 5 V loads with rail-referenced saturation. Use Value: VI(off) ≤ 0.8 V guarantees solid logic-low rejection; fT = 230 MHz supports clean edges up to 10 MHz toggle rates. |
Use Scenario: Enabling/disabling power to sensor modules (e.g., I²C temperature sensors) in battery-powered IoT nodes. IC Role / Device Role / Timing Role: Low-quiescent-current switch controlling VCC path to downstream ICs; GND1/GND2 isolation prevents ground loop coupling. Use Value: ICEO ≤ 5 µA at 150 °C ensures <1 µA leakage in sleep mode; Ptot = 300 mW allows simultaneous dual-channel activation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMD12 | PNP/PNP complement; same SOT666 package, 50 V, 100 mA, R1 = R2 = 47 kΩ. | Required for high-side switching or inverted logic polarity; not interchangeable without circuit redesign. | Select when sourcing complementary drive (e.g., push-pull output stages) or negative-rail referenced loads. |
| PEMB2 | PNP/PNP version with R1 = 10 kΩ, R2 = 10 kΩ; otherwise identical ratings and package. | Higher base current draw (≈5×) limits use with weak-drive MCUs; better suited for 5 V-only systems with ample drive strength. | Prefer only if existing design uses 10 kΩ bias networks and requires PNP logic inversion; not drop-in for PEMH2. |
Compared with PEMD12 and PEMB2, PEMH2 provides true NPN/NPN logic-compatible switching with optimal 47 kΩ bias for modern low-voltage MCUs - offering superior noise immunity, lower input current, and direct compatibility with 3.3 V GPIO without level shifters.

FAQ
What is the maximum operating temperature for PEMH2?
The PEMH2 has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Derating begins above 25 °C ambient: total device power dissipation drops linearly from 300 mW at 25 °C to 0 mW at 175 °C, per the published derating curve.
Can PEMH2 replace two separate BC847B transistors?
Yes - but only in digital switching applications where base bias resistors are used. PEMH2 integrates R1/R2 = 47 kΩ networks per channel, eliminating four external resistors. Unlike BC847B, it lacks flexibility for analog gain control or variable bias, and pinout differs (SOT666 vs SOT23).
Is PEMH2 qualified for automotive applications?
No. Per Nexperia's revision history and legal disclaimers, PEMH2 is explicitly marked as non-automotive qualified. It has not undergone AEC-Q101 stress testing or automotive-grade qualification - use only in industrial, consumer, or commercial applications.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 (typical) ensures symmetrical base current division, resulting in consistent VCE(sat) and hFE across both transistors. This matching minimizes channel-to-channel timing skew and output voltage variation - critical for synchronized dual-load control.
