Product details
Overview
PEMD2 from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP silicon bipolar transistor with built-in bias resistors (R1 = R2 = 22 kΩ) in a single SOT666 package. It delivers 100 mA output current per transistor, supports 50 V collector-emitter voltage, and serves as a compact logic-level interface driver in space-constrained digital control circuits.
For engineers reviewing the PEMD2 datasheet, PEMD2 pinout, PEMD2 application, or PEMD2 equivalent, this device is selected for low-current peripheral driving, IC input control, and replacement of discrete transistor pairs where component count reduction and simplified PCB layout are critical design goals.
Technical Context
The PEMD2 implements a dual-transistor topology with complementary polarity: TR1 is an NPN transistor with grounded emitter (Pin 1), base-driven via Pin 2, and collector output on Pin 6; TR2 is a PNP transistor with grounded emitter (Pin 4), base-driven via Pin 5, and collector output on Pin 3. Both transistors share identical bias resistor values (22 kΩ) and ratio (R2/R1 = 1.0).
Its operation relies on integrated base bias networks that eliminate external resistors - enabling direct connection to CMOS/TTL logic outputs. The device operates within −55 °C to +150 °C ambient range, with thermal resistance of 417 K/W (per device) on FR4 PCB, and supports switching at up to 230 MHz (TR1) and 180 MHz (TR2) transition frequency.
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 interfaces. |
| IO | 100 mA - Continuous DC output current per transistor; sufficient for LED drivers, small relays, and gate inputs. |
| R1 / R2 | 22 kΩ ±30% - Integrated base bias resistors reduce external component count and improve layout reproducibility. |
| hFE | 60 min - DC current gain at IC = 5 mA, VCE = 5 V; ensures reliable saturation under standard logic drive conditions. |
| VCE(sat) | 150 mV max - Low saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes power loss in switching applications. |
| fT (TR1) | 230 MHz typ - Transition frequency enables use in moderate-speed digital signal routing and pulse shaping. |
| Ptot (device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C on standard FR4; sets thermal derating baseline for layout planning. |
Pinout & Package
SOT666 is a 6-pin ultra-small flat-lead surface-mount plastic package measuring 1.6 mm × 1.2 mm × 0.55 mm with 0.5 mm pitch. Its low profile and symmetric pin layout support high-density PCB assembly and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 (emitter TR1) | Emitter reference node for NPN transistor; connects to system ground or low-side return path. |
| 2 | I1 (base TR1) | Logic-level input for NPN transistor; accepts 1.7–2.5 V turn-on threshold with internal 22 kΩ pull-up to VCC. |
| 3 | O2 (collector TR2) | Active-low output node for PNP transistor; sinks current when TR2 is on (I2 driven low). |
| 4 | GND2 (emitter TR2) | Emitter reference node for PNP transistor; connects to system VCC or high-side supply rail. |
| 5 | I2 (base TR2) | Logic-level input for PNP transistor; turns on TR2 when pulled below ~0.8 V (VIoff). |
| 6 | O1 (collector TR1) | Active-high output node for NPN transistor; sources current when TR1 is on (I1 driven high). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-polarity RET | Single SOT666 package replaces two discrete transistors + four bias resistors - reduces BOM count by ≥6 parts. |
| Matched bias network | R1 = R2 = 22 kΩ (±30%) with ratio tolerance of 0.8–1.2; ensures consistent switching thresholds across both transistors. |
| Low-input-threshold logic interface | VI(on) = 1.7 V (min) for TR1 and VI(off) = 1.1 V (typ) for TR2 - compatible with 3.3 V and 5 V CMOS outputs without level shifters. |
| Thermally robust construction | Rth(j-a) = 417 K/W (per device) on FR4; supports continuous operation up to 125 °C ambient with proper board copper area. |
| High-frequency capability | fT = 230 MHz (TR1) and 180 MHz (TR2); enables clean edge response in clock buffering and data line conditioning. |
Applications
| LED Driver Interface | Digital Input Conditioning |
|---|---|
Use Scenario: Driving multiple low-current indicator LEDs from microcontroller GPIO pins with limited drive strength. IC Role / Device Role / Timing Role: Acts as a dual-channel level-shifting buffer: TR1 drives LEDs anode-to-VCC, TR2 drives cathode-to-ground. Use Value: Eliminates need for external base resistors and separate NPN/PNP pairs, reducing footprint by >40% versus discrete solution. |
Use Scenario: Converting noisy or floating digital signals (e.g., switch inputs, sensor alerts) into clean, rail-referenced logic levels for MCU inputs. IC Role / Device Role / Timing Role: Provides active pull-up/pull-down via complementary RET structure to suppress bounce and EMI-induced glitches. Use Value: Achieves <1 µs propagation delay and <100 nA leakage in off-state - improves noise immunity without RC filtering. |
| Peripheral Enable Control | Bus Line Termination Switch |
Use Scenario: Enabling/disabling power to low-power peripherals (e.g., sensors, UART transceivers) based on system sleep/wake state. IC Role / Device Role / Timing Role: Functions as a dual-rail enable switch: TR1 controls VCC to peripheral, TR2 controls GND return path. Use Value: Delivers full 100 mA per rail with <150 mV saturation drop - limits voltage droop and thermal rise during sustained load. |
Use Scenario: Dynamically enabling/disabling termination resistors on I²C or SPI bus lines to reduce standby current in multi-node systems. IC Role / Device Role / Timing Role: Replaces mechanical jumpers or MOSFETs with integrated bipolar switches controlled by host controller GPIOs. Use Value: Enables sub-µA off-state current (ICEO < 5 µA at 150 °C) and eliminates gate charge delays inherent in MOSFET solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMH1 | NPN/NPN configuration; same SOT666 package, 50 V/100 mA rating, matched 22 kΩ bias network. | Used where dual-sourcing or push-pull NPN logic is required instead of complementary NPN/PNP pairing. | Select when circuit requires two active-high outputs or symmetrical sourcing capability. |
| PEMB1 | PNP/PNP configuration; same package and electrical specs, but no NPN element. | Preferred in high-side switching arrays or negative-rail interface designs requiring dual sinking paths. | Choose when both outputs must sink current relative to VCC, e.g., in automotive body control modules. |
Compared with PEMH1 and PEMB1, the PEMD2 uniquely provides complementary polarity in one package - enabling true push-pull digital interfacing without cross-conduction risk, making it optimal for bidirectional signal conditioning and rail-flexible I/O expansion.

FAQ
What is the maximum operating temperature for PEMD2 in continuous use?
The PEMD2 has a maximum junction temperature of 150 °C and specified ambient operating range of −55 °C to +150 °C. When mounted on a standard FR4 PCB with single-sided 35 μm copper, its thermal resistance is 417 K/W; derating begins above 25 °C ambient, reaching zero power at ~125 °C ambient per the published derating curve.
Can PEMD2 be used in analog amplification applications?
No - the PEMD2 is optimized for digital switching, not linear amplification. Its hFE variation over temperature and current (60–200), lack of guaranteed linearity specs, and integrated bias resistors preclude stable small-signal gain control. It should only be used in saturated-switch or logic-buffer roles per datasheet-defined conditions.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 ensures matched base current scaling between TR1 and TR2, maintaining consistent VI(on)/VI(off) thresholds across both transistors. This tight ratio prevents timing skew in complementary switching and guarantees predictable turn-on/turn-off sequencing when both inputs are driven simultaneously.
Is PEMD2 automotive-qualified?
No - according to the March 2023 datasheet revision history, PEMD2 was explicitly changed to non-automotive qualification. It is not tested or certified to AEC-Q100 standards and lacks automotive-grade screening, traceability, or extended temperature validation beyond the stated −55 °C to +150 °C ambient limit.
