Product details
Overview
PEMH30 from Nexperia (formerly Philips Semiconductors) is an NPN/NPN double resistor-equipped transistor (RET) in SOT666 package, integrating two matched NPN transistors with built-in 2.2 kΩ input bias resistors (R1), rated for 50 V VCEO, 100 mA output current per transistor, and used as low-current peripheral drivers in digital logic interface circuits.
For engineers reviewing the PEMH30 datasheet, PEMH30 pinout, PEMH30 application, or PEMH30 equivalent, key selection considerations include dual-transistor integration, open-collector output capability, thermal resistance (416 K/W per device), bias resistor tolerance (±30%), and compatibility with reflow-only assembly on FR4 PCBs.
Technical Context
This dual RET implements two independent NPN transistors sharing no internal connection between collectors or emitters-each has dedicated base-input (with integrated R1 = 2.2 kΩ), emitter-GND, and collector-output terminals. The R2 resistor is open, confirming single-bias-resistor topology per transistor.
It operates as a logic-level interface device: input voltage applied to pin 2 or pin 5 switches the corresponding transistor into saturation (VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA), enabling direct drive of IC inputs or LED loads without external base resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with base open; defines maximum load supply rail compatibility. |
| IO | 100 mA per transistor - Continuous DC output current rating; supports driving small-signal loads like logic gates or indicator LEDs. |
| R1 | 2.2 kΩ (±30%) - Integrated base bias resistor; eliminates need for discrete pull-up/pull-down components and reduces BOM count. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - Total power dissipation limit for both transistors; constrains simultaneous high-current operation. |
| Rth(j-a) | 416 K/W - Junction-to-ambient thermal resistance in free air; determines temperature rise under load without heatsinking. |
| hFE | 30 min at VCE = 5 V, IC = 20 mA - Minimum DC current gain; ensures reliable saturation with standard logic-level base drive. |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage enables efficient switching and minimal voltage drop in active-low outputs. |
Pinout & Package
SOT666 plastic surface-mounted package (6-pin, 1.7 × 1.5 mm footprint); moisture sensitivity level (MSL) 1, reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Emitter terminal of first transistor; common reference node for input/output biasing and current return path. |
| 2 | input (base) TR1 | Base input of TR1 with integrated 2.2 kΩ resistor to VIN; accepts TTL/CMOS logic signals directly. |
| 3 | output (collector) TR2 | Collector output of second transistor; open-collector configuration enables wired-OR logic or level shifting. |
| 4 | GND (emitter) TR2 | Emitter terminal of second transistor; electrically isolated from Pin 1 but functionally identical GND reference. |
| 5 | input (base) TR2 | Base input of TR2 with integrated 2.2 kΩ resistor; independently controllable from TR1 for dual-channel logic interfacing. |
| 6 | output (collector) TR1 | Collector output of first transistor; complements Pin 3 to provide two independent open-collector outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET integration | Two fully independent resistor-equipped transistors in one SOT666 package-reduces PCB area by ~40% vs. discrete BC847BS pairs. |
| Built-in 2.2 kΩ bias resistors | Eliminates four external base resistors per pair; cuts pick-and-place cycle time and improves assembly yield. |
| Open-collector outputs | Enables direct interface with 3.3 V or 5 V microcontroller GPIOs and supports wired-AND/wired-OR bus topologies. |
| Reflow-only assembly support | Qualified for lead-free reflow per JEDEC J-STD-020; no wave soldering allowed-ensures reliability in automated SMT lines. |
| 150 °C junction temperature rating | Supports operation in industrial ambient environments up to +105 °C with appropriate derating per thermal data. |
Applications
| Logic Level Translation | LED Driver Interface |
|---|---|
|
Use Scenario: Converting 1.8 V FPGA I/O signals to 5 V-compatible control lines for legacy peripherals. IC Role / Device Role / Timing Role: Dual RET acts as bidirectional level-shifting buffer with independent enable control per channel. Use Value: Eliminates need for dedicated level translators; leverages existing 2.2 kΩ R1 to match input impedance requirements of downstream 5 V receivers. |
Use Scenario: Driving status LEDs from low-power MCU GPIO pins with current limiting handled internally. IC Role / Device Role / Timing Role: Each transistor functions as a saturated switch controlling LED anode/cathode current path. Use Value: Achieves 10–20 mA LED current using only VCC, GPIO, and LED-no external current-setting resistors required. |
| Microcontroller Input Conditioning | Pushbutton Debounce Circuit |
|
Use Scenario: Cleaning noisy mechanical switch inputs before feeding into interrupt-capable MCU pins. IC Role / Device Role / Timing Role: One RET stage provides Schmitt-trigger-like hysteresis via resistor feedback; second stage buffers signal to MCU. Use Value: Reduces firmware debounce overhead; built-in R1 sets consistent input threshold across temperature (−40 °C to +105 °C). |
Use Scenario: Generating clean, glitch-free clock edges from tactile button presses in real-time systems. IC Role / Device Role / Timing Role: First transistor conditions raw switch signal; second provides edge-triggered output synchronized to system clock domain. Use Value: Enables hardware-based debouncing with <5 µs propagation delay-critical for deterministic interrupt latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BS | Discrete dual NPN transistor pair without bias resistors; requires four external 2.2 kΩ resistors. | Higher component count and layout area; suitable when design requires adjustable base bias or higher hFE (>110). | Select when fine-tuned gain or thermal separation between transistors is required; not drop-in compatible. |
| PUMH30 | Same electrical specs but in SC-88 (SOT363) package; smaller footprint (2.0 × 1.25 mm), higher thermal resistance (625 K/W per device). | Better suited for space-constrained portable designs; lower power handling due to reduced Ptot (200 mW per device). | Choose for ultra-dense layouts where board area savings outweigh thermal derating needs. |
Compared with BC847BS and PUMH30, PEMH30 offers optimal balance of thermal performance (300 mW Ptot, 416 K/W Rth) and standardized SOT666 assembly compatibility-making it preferred for industrial control modules requiring long-term reliability and process consistency.

FAQ
Is PEMH30 RoHS compliant and halogen-free?
Yes, PEMH30 meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The SOT666 package uses lead-free matte tin plating, and all materials comply with Nexperia's Eco Plan requirements effective from 2006 manufacturing lots.
Can PEMH30 be used in linear amplifier configurations?
No-PEMH30 is characterized and qualified exclusively for switching operation. Its hFE is specified only at IC = 20 mA and VCE = 5 V, and no linearity, frequency response, or noise parameters are provided in the datasheet. It lacks bias stability for analog amplification.
What is the maximum allowable peak current per transistor?
The absolute maximum peak collector current is 100 mA for single pulses ≤1 ms (per Table 6). This limit applies regardless of duty cycle or ambient temperature and must not be exceeded to prevent irreversible junction damage.
Does PEMH30 support reverse-voltage protection on its inputs?
No. The base-emitter junction has a maximum reverse voltage rating of 5 V (VEBO). Applying negative voltage beyond this-such as −0.3 V on pin 2 or pin 5 relative to pin 1 or pin 4-can cause permanent degradation of hFE or leakage increase.
